The husker roller is a rubber roller used on the husker to husk the rice. As an important accessory on the husking machine, the material of the husking rubber roller will directly affect its performance. Generally, the commonly used husking rubber roller includes five materials: butadiene-styrene rubber roller, polyurethane rubber roller, nitrile rubber roller, high wear-resistant rubber roller and strong wear-resistant rubber roller. Among them, the strong wear-resistant rubber roller has superior performance, but the cost performance is not necessarily high. It is still necessary to select the rubber roller of suitable material according to the production needs.

The basic performance of the husking rubber roller (the amount of grain grinding) depends on the physical and mechanical properties of the external rubber compound, and the performance is as follows

The husking rubber roller is the main accessory on the husker and the key equipment for rice husking. The working principle is that the two rubber rollers rotate at a reverse unequal speed to make the rice enter between the two rollers to play the role of squeezing, tearing, rubbing and peeling, so as to achieve the purpose of shelling into rice. The colors of the outer layer of the husk rubber roller are: brown, black, white, red, yellow, purple, gray, beige, blue, green, etc., the color can be determined according to the demand

The process of grain shelling generally goes through three basic steps: squeezing, rubbing and tearing, and peeling. Among them, rubbing and tearing is the key to shelling. The size of rubbing and tearing depends on two important factors: one is the size of friction, and the size of friction depends on the size of the pressure between the two rollers; The second is the length of the relative action time of this reverse friction on the grain, the length of this action depends on the relative speed of the two rollers, that is, the line speed difference. It is not difficult to see: the pressure between the rollers and the line speed difference is an important process parameter of rice shelling, the choice of its correct or not not only directly affect the shelling rate, but also affect the consumption of rubber rollers.

Tearing strength: MPa 19 (190K/cm2) or more

The classification of rubber rollers, structural forms and extremely models: At present, there are three categories of husking rubber rollers in China and the world, also known as three series, named: wheeled, sleeve, and lap.

Since the rubber roller husker replaced the sand plate husker and iron roller rice mill, it has become a special equipment for rice husking in the rice milling industry, with its large output, high husking rate, low rice crushing rate, less power consumption, convenient operation and other advantages, it is widely used by various rice processing plants. With the increasing development of the rice milling industry, the rubber roller husker is constantly improving and becoming more and more perfect. For example, the emergence of the husker of the single-machine transmission fluid pressure roller of the gear box is undoubtedly a replacement product, but no matter how complicated its structure is and how perfect its performance is, it is always the same. Its basic principle is the same, that is, by means of the reverse unequal speed rotation of the two rubber rollers next to each other, the eight-rolled rice is squeezed, torn and other effects, thus achieving the purpose of shelling. Therefore, the husking rubber roller is an indispensable vulnerable spare part on the husking machine.

Up to now, there are about 400 rubber roller manufacturers in 400 country, but most of them are small workshop-style processing factories in various places. These factories are small in scale, single in product and poor in technology. They are characterized by low price and convenient in supply. Printing rubber roller products can only be matched and renovated for low-grade printing machines, with an output value of only several million yuan. Therefore, the rubber roller industry in our country is still in the backward technical level and production level. However, although China's rubber roller industry still has a great development trend, especially the rise of the printing industry, has accelerated the development of the rubber roller industry. Many printing companies need a lot of rubber rollers

Due to the frequent errors in the measurement of ingredients in the production of rubber products, the problem of low yield of rubber roller products occurs in the production process, which ultimately leads to poor product performance stability. This problem has been plagued by manufacturers, especially with the gradual increase in the yield of product varieties, more and more roller factories are more urgent to solve this problem, strengthen the quality control of the mixture, and improve the internal quality of the product. Recently, this problem has finally been solved, because the first domestic microcomputer automation CNC rubber production line was officially built. The production line is currently the most advanced automated CNC rubber production equipment in the international rubber roller industry, which makes up for China's

Compared with solid silica gel, foamed silica gel has many special and valuable properties due to its special structure, that is, porosity, such as: (1) low apparent density, light weight and material saving; (2), Rich in elasticity and flexibility, with excellent dust, water and gas sealing effect; (3), improved heat insulation performance, with low thermal conductivity; (4), improve the ability to absorb impact load, with excellent cushioning and shock absorption performance; (5), improve sound insulation, sound absorption effect; (6), improve the touch, improve comfort; (7), physical properties change range Large, change the apparent density

The rubber industry uses a large number of fillers as compounding agents, and its dosage is second only to rubber consumption. Reinforced filler used in rubber, not only can improve the strength of rubber products, but also can improve the processing performance of rubber, and give products good wear resistance, tear resistance, heat resistance, cold resistance, oil resistance and other properties, can extend the service life of products. Non-reinforcing filler for rubber, mainly from the role of filling capacity, some varieties also have the role of isolation, demoulding or coloring. Rubber products on the filler requirements 1 general requirements (1) reinforcing filler particle surface to have strong chemical activity, can produce a good combination with rubber, can improve the vulcanization

1, silicone products molding, after a large pressure, due to the elastomer is available within the force can not be eliminated, in the molding away from the mold, often produce very unstable shrinkage (silica gel shrinkage rate, due to different kinds of glue and there are differences), must be after a period of time, in order to slow and stable. Therefore, when a silicone product is designed at the beginning, regardless of the formula or mold, it is necessary to carefully calculate the coordination. If not, it is easy to produce unstable product size and low product quality. 2. Silicone is a hot-soluble thermosetting elastomer, while plastic is hot-soluble and cold-cured. Silica gel due to the different types of sulfide main body, its molding curing temperature range, there are also phases.

Rubber products often require some post-processing after vulcanization to become qualified finished products. This includes: ① trimming of rubber mold products to make the surface of the products smooth and clean and the external dimensions meet the requirements; ② through some special process processing, such as surface treatment of the products, to improve the performance of special purpose products; ③ products containing fabric frames such as adhesive tapes, tires and other products should be cooled under inflation pressure after hot stretching and vulcanization, to ensure product size, shape stability and good performance. Trimming of 1. mold products after vulcanization of rubber mold products during vulcanization
