Professional rubber roller manufacturer professional analysis shows that the professional roller roller manufacturer of silicone roller professional analysis is a silicone roller Looking for the quality of the silicone roller recommended for you to Dongguan Haichang Hardware Rubber, Dongguan Haichang Hardware Rubber Co., Ltd. was established in 2001, is a professional manufacturer of various industrial rubber roller and printing machinery rubber roller. Over the years, relying on strong technical force, advanced machinery and equipment "target=_blank> mechanical equipment, scientific management mode and pragmatic spirit of refinement, with integrity and quality as the purpose, the market share continues to expand, praised by the majority of users . 1) Introduction to silicone roller It is made of metal or other materials and is covered with silicone rubber. It has high temperature resistance, ozone resistance, chemical inertness and non-adhesion to plastics. It is mainly used for processing hot-adhesive products such as polyethylene calendering, embossing and printing. And film and fabric coating adhesive, plastic composite, corona treatment and other machinery, also used as a sugar production and packaging machine on the release roll and non-woven fabric manufacturing. Generally speaking, the silicone roller refers to the rubber roller on the heat transfer machine, which is used for the pattern printing special rubber roller on the thermal transfer of toys, electronics, craft gifts and bronzing products. 2) Heat-resistant silicone roller features 1. Excellent high and low temperature resistance, working temperature range -100 to 350 degrees. Excellent resistance to ozone aging, oxygen aging, photoaging and weathering. There is no change in the performance of the silicone roller in the free state for several years, so it is convenient to use the silicone roller in many industries. 2, excellent electrical insulation properties, the electrical insulation properties of silicone roller changes little when the moisture, frequency changes or temperature rise, the silica formed after combustion is still an insulator, so in some environments requiring insulation, silica gel The roller is also used more frequently. In addition, since the silica gel has a small carbon atom in the molecular structure and does not use carbon black as a filler, scorch is less likely to occur during arc discharge, and thus it is very reliable for use in high pressure applications. Its corona resistance and arc resistance are extremely good, the corona life is 1000 times that of polytetrachloroethylene, and the arc life is 20 times that of fluororubber. 3. The silicone roller has special surface properties and physiological inertness. The surface energy of the silicone roller is lower than that of most organic materials. Therefore, it has low hygroscopicity and is immersed in water for a long time. Its water absorption is only 1%, the physical and mechanical properties are reduced, and the mildew resistance is good. Therefore, silica gel is also used in underwater operations or in a humid environment. In addition, the silicone roller does not stick to many materials and can act as an insulator. 4, silicone rubber tasteless and non-toxic has no adverse effects on the human body, the body reacts slightly, has excellent physiological inertia and physiological aging. 5, high gas permeability, silicone roller and other polymer materials have superior gas permeability, the transmittance in the air at room temperature is 30-40 times that of natural rubber, in addition, the silicone roller also has a gas The selectivity is different for the gas permeability of different gases. 3) Use of silicone roller 1. When starting the heating, check whether the silicone roller rotates normally. When shutting down, please pay attention to whether the residual temperature delay is normal, not directly shut down, and the residual temperature delay is set at 40-50 minutes; 2. When the machine is in operation, if it is suddenly powered off due to power failure or other reasons, immediately put on the glove, remove it and put it away in other places to dissipate heat to avoid heat unevenness and burn the silicone roller; 3. When replacing the rubber roller tightly, the silicone should be locked and fixed when the silica gel is heated to the required temperature, but it should not be too tight; 4, silicone roller should keep the surface clean, try to avoid the transfer film debris and other glue to the surface of the rubber roller, such as the surface has dirt, can be used to add industrial alcohol to clean the surface. If stubborn dirt can be polished with fine sandpaper. 5. Like other printing rubber rollers, when used or stored, the silicone roller should not collide with other hard objects and be squeezed; away from corroded articles; 6. The temperature of the silica gel can be normally transferred after 190 degrees. In the case of qualified product transfer, the pressure and temperature of the silicone roller should be minimized.

In the printing process, due to the repeated contact between the water roller and the printing plate, after a period of time, the ink and other impurities will be detached from the printing plate on the one hand, and the velvet structure on the surface of the water roller will be damaged. In the process of transferring water, the surface velvet structure of the roller will be subject to the same damage; at the same time, the ink on the water roller will be transmitted to the water transfer roller through the hydrophobic roller. Therefore, the water roller fleece must be cleaned or replaced in time to restore and maintain water absorption and water transfer performance. First, prepare cleaning materials and tools (1) cleaning materials: gasoline, water (preferably a pool with a tap); (2) Tool nylon brush and steel sheet. Second, cleaning Put both ends of the removed water roller on the bracket (or wooden pillow) of the water roller, pour the gasoline on the roller surface, and use the plate brush to brush evenly in one direction (the direction of the silk of the water roller velvet); After the ink is dissolved, it is flushed with water until the roller surface is free of dissolved ink. Finally, the excess moisture is scraped off with steel. (a) Cleaning of waterfighting sticks and water roller The more common water roller is chrome plated. In the printing process, the ink stain on the water roller is also transmitted to the hydrophobic roller and the roller roller, which reduces the water transfer. In addition, when the downtime is long, even if the fountain roller and the fountain roller are not contaminated by ink, an oxide film is formed on the surface, and the surface of the roller absorbs oil mist and other impurities in the air, so that they are Some hydrophilic properties have changed. Therefore, the bucket roller and the squeegee roller must be cleaned in a timely and regular manner so as to restore its hydrophilicity and uniform water transfer. Cleaning materials: pumice powder, fountain solution, glue, and wipes. (1) Draw the dampening stock solution, and then pumice powder, and then rub it back and forth on the surface of the hydrophobic roller and the fountain roller. When the ink and oxide film are removed, quickly wipe the surface with a wet cloth. (2) Jog the machine, go to the remaining uncleaned parts, and wipe it according to the appeal method until all the two rollers are cleaned. (3) Use a water cloth to pick up the glue and wipe the surface of the roller. (b) Cleaning of the bucket Bucket is generally made of copper alloy material. The long-term use of the bucket will inevitably fall into the dust and other debris. At the same time, the bucket roller will also bring paper powder, paper hair, and ink stains into the bucket. This will not only reduce the wetting property of the fountain solution. , And will directly affect the printing quality of printed products. 1, cleaning steps (1) Prepare clean water and a cloth, a brush, and a plastic tube. (2) Remove the fountain roller (3) Pour the water into the bucket and use a brush to stir up the contents of the bottom of the bucket. Then use the conduit (the principle of the connected device) to suck out the turbid liquid in the water. While watering, brushing and guiding the water until the bucket is basically clean, the bucket is thoroughly cleaned with a cloth. (4) Install the fountain roller 2, easy to produce problems and precautions (1) When disassembling the water roller, care should be taken to ensure safety. The disassembled water roller should be placed on the water roller bracket if it is not to be used or installed immediately. (2) When cleaning the water transfer roller and the water roller, the direction of brushing and scraping should be consistent with that of the water roller velvet. (3) When cleaning the fountain roller and the hydrophobic roller, the amount of pumice powder should be as small as possible, and pumice powder should be avoided from falling into the surface of the bucket or the water roller. (4) The water roller should be cleaned in time, otherwise it will reduce the water delivery performance of water delivery components, resulting in the production of dirty plates and other ills. The time for cleaning the water roller and the water bucket should be determined by the degree of fouling and the specific conditions. The general rule is: 1) When stopping for a long time or changing fine products, clean the water roller and the water bucket thoroughly before turning on the machine. 2) During the normal printing process, if the ink layer of the layout is thick, the water roller should be cleaned every day; if the layout graphic is thin or the general product is printed, the cleaning frequency can be appropriately reduced. 3) The ink stains on the water roller and the water roller should be cleaned in time, otherwise the local water supply of the printing plate will be insufficient, resulting in the failure of the dirty plate and the like. At the same time, the water roller may be easily stained with ink. 4) When replacing dark ink with light ink, be sure to clean or replace the water roller. 5) Before the new water roller is printed on the machine, apply a clean, wet cloth to wipe gently in the direction of the ridge of the water roller velvet to remove floating fluff on the surface of the water roller. Then, wipe the surface of the water roller with a suitable amount of water or dampening solution with a water wiper, so that the new water roller has a certain amount of water before the machine is on, so as to facilitate printing. The new water roll on the machine, you can make the machine idling for 10 ~ 20min, in order to make up for the water content of the water roller, and then shut down to wipe off the fluff on the water roller and the roller roller. (3) Cleaning of ink fountains and ink paths 1, ink fountain cleaning: (1) Prepare ink knives, containers for remaining ink, gasoline, and two wipes (2) Scooping: Scoop out the ink in the ink fountain with a knife. (3) Remove the ink fountain (4) Cleaning the ink fountain roller: Use a cloth to draw the gasoline, scrub the ink on the ink fountain roller, and completely dissolve the ink. Then wipe the ink fountain cleanly with a clean cloth to make it look shiny. (5) Cleaning ink fountain (6) Return the ink fountain to its original working position. If it is not turned on for a long time, keep the ink fountain and the ink fountain roller separate. 2.Ink roller cleaning (1) daily cleaning In the printing process, when the color change is required, the printing is finished every day or in special cases, the ink roller is often required to be cleaned. (The cleaning process is omitted.) Therefore, cleaning the ink roller is one of the basic contents of daily operations. (2) Special cleaning methods In order to improve the life of the rubber roller and the quality of the product, the rubber roller must be removed periodically and cleaned by the root. This work is especially important when the rubber roller suffers from an ink failure such as oxidized conjunctiva or deinking. 3, roll oxidation conjunctiva Refers to the ink in the connection material and driers and other substances penetrate the rubber roller for a long time, so that the surface of the roller seals the pores, thus forming a smooth oxide film. There are four ways to remove the oxidized conjunctiva of the roller: 1 Put the ink roller on the stand, use a clean cloth to take the appropriate amount of kerosene first, then pumice powder and wipe the surface of the roller firmly until the smooth surface of the roller is wiped off. This method of scrubbing the ink roller is the most common method of periodically scrubbing the ink roller. 2 Scrub the ink roller with about 20% aqueous sodium hydroxide solution, then neutralize with weak acid, then rinse with water and wipe dry. 3 Wet the ink roller with about 10% aqueous sodium hydroxide solution, then wipe it with kerosene and pumice powder with a cloth. Finally, rinse with water and wipe dry. 4 Moisten the ink roller with kerosene and sand it with a finer emery cloth. When operating, the rotating ink roller should be even and the force should be light and consistent so as not to cause the roller to be uneven. This method is more thorough than the above method, but due to the difficulty in mastering, it also has great damage to the ink roller itself. Generally, it must be used with caution. 4, ink roller deinking That is, due to the poor performance of ink emulsification and transfer of ink by the ink roller, a hydrophilic foundation is formed on the surface of the ink roller, and the ink roller does not absorb ink. This phenomenon is common when printing yellow or black, especially on domestic small offset presses. Treatment of deinking of iron (or copper) squeegee roller: Wash the emulsified ink on the roller with gasoline first, then use kerosene and kerosene to clean the roller thoroughly, and then use a clean. The cotton gauze is taken with a copper plating solution (copper sulfate solution) to evenly wipe the surface of the ink roller. After the bright copper layer has formed on the surface of the ink roller, wipe the ink roller again with a piece of gasoline cloth. De-inking of rubber rollers: If used and maintained improperly, the plastic (or nylon) roller and the rubber roller will still be de-inked. The deinking process of the plastic ink roll and the aging process of the rubber roll are basically the same. Wash the roll with gasoline first, then use a cloth to remove 5% sodium hydroxide solution and pumice powder, and wipe the ink roller vigorously. The surface is wiped off until the film layer with the smooth surface of the ink roller is wiped off. Finally, the ink roller is washed with gasoline. However, the best way to prevent deinking is to prevent it, that is, to make appropriate adjustments from the process, such as: reducing the acidity of the fountain solution, reducing the amount of glue, reducing the layout of water and so on. 5, prone to problems and precautions: (1) The ink fountain cannot be cleaned during the operation of the machine. (2) If the ink fountain or the ink path is not cleaned properly, the following problems will occur: 1) When dark ink is replaced with light ink, light ink is seriously affected by dark ink. Therefore, when cleaning light ink, when the ink of the primary ink is cleaned, some light ink should be added to the ink fountain. Clean it with ink. If you still feel it is not washed, repeat it again. 2) The ink is dry on the ink fountain roller, the ink fountain blade and the ink roller, affecting the normal transmission of the ink, and even causing the failure of the rubber roller to deink and produce. 3) The rubber roller should be removed periodically for cleaning. The regular cleaning interval is one week. 4) When cleaning the rubber roller, it is strictly prohibited to use ketone and ester organic solvents for cleaning.

The production process of the rubber roller generally follows several procedures such as preparation of the rubber material, molding of the rubber roller, vulcanization of the rubber roller, and surface treatment. To date, most companies still produce intermittent, unit-based operations that are primarily man-made. In recent years, with the continuous development of techniques such as injection, extrusion and winding, the rubber roller forming and vulcanizing equipment has enabled the production of rubber rollers to gradually embark on the fast track of mechanization and automation. In order to achieve a continuous production from the rubber to the molding and vulcanization process, the production efficiency is exponentially improved, and the working environment and labor intensity are greatly improved. Since the rubber surface of the rubber roller does not allow any impurities, trachoma and air bubbles, but also can not have the phenomenon of scars, defects, grooves, cracks and local sponge and soft and hard. Therefore, only in the entire production process, the rubber roller keeps absolute cleanliness and fine workmanship, realizes the unification of operation and technical standardization, and can guarantee the quality of the batch product. At present, the combination of rubber and metal cores, bonding and injection molding, vulcanization and grinding processes have become high-tech processes. Rubber roller production process rubber preparation For rubber rollers, compounding is the most critical link. The types of rubber used in rubber rollers range from natural rubber and synthetic rubber up to more than 10 kinds of special materials, with a gel content of 25% to 85% and a hardness of 0 to 90 degrees, which spans a very large range. The conventional method is to use an open-type rubber mixer for mixing and processing in the form of a plurality of master batches. The so-called rubber mixing machine is a kind of rubber mixing machine that is used in the rubber factory to prepare mixed rubber or to hot-smelt, plasticate, and form the rubber. However, these are a kind of mixed plastic equipment. In recent years, companies have switched to more intermeshing mixers and made rubber compounds by sub-mixing. After the rubber material is evenly mixed, the filter is used to remove the impurities in the compound. Then use a calender, an extruder, and a laminator to make a film or stripe without bubbles and impurities for molding the roller. Prior to molding, these films and strips are subjected to rigorous visual inspections and fresh surfaces are kept from blocking and squeezing. The rubber on the surface of the film and rubber strip must be free from impurities and air bubbles, otherwise blisters may occur when the surface is ground after vulcanization. Roll forming of rubber roll manufacturing process Roller molding is mainly used to paste coating rubber on metal cores. Common methods include wrapping, extrusion, molding, injection and injection. At present, most domestic companies mainly rely on mechanical or hand-adhesive molding, and most foreign companies have already achieved mechanical automation. Large and medium-sized manufacturing companies basically adopt profiling extrusion methods, which are produced by continuous extrusion molding of extruded film or continuous winding and molding of extruded tape. At the same time, in the molding process, the size and appearance of the machine are automatically controlled by a microcomputer, and some of them can also be formed by a right angle and special extrusion method of the extruder. The use of profile extrusion and automatic computer-controlled molding methods can eliminate possible air bubbles and also minimize labor intensity. In the process of molding by the sticking method, in order to prevent the rubber roll from being deformed in the vulcanization and prevent the generation of air bubbles and sponges, a flexible pressurization method is also adopted outside. Generally, several layers of cotton or nylon cloth are wrapped around the outer surface of the rubber roller, and fixed and pressed with steel wire or fiber rope. For small and micro-rubbers, various manufacturing processes such as manual patching, extrusion nesting, injection molding, injection and casting can be used. In order to increase production efficiency, moulding methods are now mostly used, and the accuracy is much higher than that of non-molding methods. Solid rubber injection, injection and liquid rubber casting have become the most important production methods.

Because it is in use. Examples of fractures from this part, subject to structural and usage limitations, we propose the following solutions: the bearing collar is a hole, the shaft tube is a shaft, and the joint position 0 is welded with a fillet weld, which simplifies the connection cost, while the shaft hole Positioning with tight fit improves the situation in the past where the weld was affected by the weld. The disadvantage is that the bearing sleeve is increased in size, the structural design is not reasonable, and the machining cost is high. The neck sleeve tube is between the shaft shaft holes. Tight fitting, assembly by heat assembly, heating of the sleeve body and the small shirt, easy assembly like the accuracy of the entire connecting shaft depends on 3 parts, the cumulative error increases, there are two bearing welds, the processing of complex high cost The force condition 4 is good and the bearing capacity is weakened. The bearing sleeve is used as the shaft, the shaft tube is the hole, the interference between the hole and the shaft is adopted, the heat assembly is performed, and the welding method of the plant slope is adopted. The slope welding seam is sufficient. Overlapping, welding firm, deep penetration, high efficiency of the museum, and the welding area is small, avoid heat, excessive loss, to ensure the factory welding quality. From the analysis of the force situation of the above scheme, we can see that the first scheme is ideal. In practice, we discovered that the welding art process has a great influence on the welding quality. After repeated practice, we believe that the following welding process is the better solution. 1 with 0 gas shielded welding machine. Select a wire with a diameter of 1.2 and adjust the welding flow to 200 volts to symmetrical spot welding. The spot weldability can be appropriately increased to a height that will uniformly heat the entire weld, adjust the current to 300, and adjust the current to 200 volts to 15, Welded flat can be cooled after mechanical cooling by mechanical knocking.

Functions and Features The rubber coating roller is an important accessory for the production enterprise to carry out the material conveying process in the production process, and it is also an important part of the transportation and transportation system. The rubber coating roller is used for packaging and processing the roller, and according to the production requirements of different production enterprises, the drum body of the roller is wrapped or cast. It is mainly divided into cold vulcanization and hot vulcanization methods, which are commonly referred to as encapsulation and casting. The casting rubber is a uniform layer of rubber material wrapped around the drum, and the production of the hot-glued casting rubber is more effective when used in production operations. However, the production cost of the casting rubber is relatively high. After the wear of the roller rubber surface appears on the production site, the conveyor bolts are exposed and the top tape is broken, and the rubber surface is difficult to repair immediately. The manufacturing process of hot-stick adhesives is relatively complicated. Not only does it take a long time to maintain, but also the intensity and difficulty of production work are high, and the requirements for production workers are also high. Therefore, it is difficult to meet the needs of large-scale production enterprises. The cold-vulcanized casting rubber is exposed between the upper and lower belts of the drive roller, and the selected rubber material is uniformly adhered to the surface of the roller with a normal-temperature-curing adhesive, thereby increasing the friction between the belt and the roller. force. The drum adopting the cold vulcanization rubber packaging method eliminates the heavy work of disassembling the drum and the belt, and the production process is simple. It saves labor and time in production and production, and not only the production cost is relatively low, but also used in production operations. The effect is also better. Cold glue sticking glue In the production operation, if the roller rubber surface appears damaged or worn, the drum can be repaired on the spot. At present, the cold glue sticking process is widely used. Therefore, the drum adopting the cold glue sticking process is one of the most commonly used fittings used by factories and mines in production operations for material transport production. Roller encapsulation can effectively improve the running conditions of the materials during production, prevent slippage of the conveyor belt, protect the metal roller from wear, and effectively prevent the sliding friction between the roller and the belt, thereby reducing the material on the surface of the roller. Bonding, in order to reduce the deviation and wear of the belt, so that the roller and the belt in production and transport to maintain synchronous operation, and to achieve high efficiency production of the belt in the production of transmission operation.
