Analyze the structural principle of the anti-sticking mechanism of the lower idler roller of the belt conveyor
. The structural principle of the anti-sticking mechanism (gǔn) of the lower idler (gǔn) of the belt conveyor. Technical background: The belt conveyor transports a variety of materials. When transporting the surface particles of the material, the weight of the material and the water content of the material will be seriously affected. Its effect on the conveyor belt will be reduced. A small amount of material will stick to the surface of the conveyor belt, although the use of cleaning devices can greatly reduce the transportation. Adhesion to the surface of the belt, but there is still a small amount of material on the surface of the conveyor belt, which will be reduced when passing through the conveyor belt. The dryer mesh belt is a machine that uses static friction to transport materials in a continuous manner by friction drive. Using it, the material can be formed on a certain conveyor line from the initial feeding point to the final unloading point to form a material conveying process. The chain conveyor is a kind of standard chain plate as the bearing surface, which is driven by a motor. The reducer is a transmission device for power transmission. The chain conveyor is composed of a power unit (motor), a drive shaft, a roller, a tensioning device, a sprocket, a chain, a bearing, a lubricant, a chain plate, etc. The mesh belt conveyor is not only capable of conveying bulk materials , It can also transport finished materials, but depending on the place of use, working environment, and the types of materials to be conveyed, there will be big differences in its design and application. Belt conveyors have large conveying capacity, simple structure, and convenient maintenance. The advantages of component standardization, etc., are extensively used in mining, metallurgy (content: extracting metals or metal compounds from ore), coal and other industries. It is used to transport loose materials or finished items. According to the requirements of the transportation process, it can be transported by a single unit. , It can also be composed of multiple units or combined with other conveying equipment (equipment) to form a horizontal or inclined conveying system to meet the needs of different layout types of operation lines. It is suitable for conveying bulk density (unit: g/cm3 or kg/m3) less than 1.67 /Ton/m3, easy-to-pick powdery, granular, small blocky low-abrasive materials and bagged materials, such as coal, gravel, sand, cement (material: powdery hydraulic inorganic cementitious material) , Chemical fertilizers, grains, etc. The temperature of the delivered material is less than 60°C. The captain and assemble form can be determined according to user requirements. Transmission can be electric drum or drive device with drive frame. The double-speed chain assembly line is usually called: the self-flowing conveyor system double-speed chain conveyor is mainly used for the material transportation in the assembly and processing production (Produce) line. Its transportation principle is to use the speed-increasing function of the double-speed chain to make The tooling plate on which the cargo is supported moves quickly, and stops at the corresponding operating position (position) through the stopper; or through the corresponding instructions to complete the accumulation and release action, shifting, indexing, special line and other functions. Because the platform of this machine needs to be used repeatedly, it is rarely used alone. Instead, it forms a horizontal or vertical continue system with various special machines such as jacking translators and jacking indexers. The effective combination of man and machine in the assembly line fully reflects the flexibility of the equipment. It organically combines the conveying system, the accompanying fixture, the online special machine, and the testing equipment to meet the assembly requirements of multiple varieties (Varieties) products. . Structural form: By solving the defects of the prior art, a belt conveyor lower roller anti-adhesion mechanism can be adopted, which has a simple structure and effectively reduces the adhesion on the lower support roller and the comprehensive protective conveyor belt. The structure includes: a roller ring, a shaft guard ring, and a lower supporting roller, the roller ring is sheathed on the lower supporting roller, the roller ring and the lower supporting roller are kept in relative rotation, and are in place. Shaft retaining rings are installed on both sides of the roller. The outer diameter (outer edge diameter) of the roller should be larger than the outer diameter of the lower support roller, and the cross section of the edge of the roller ring is tapered. Working principle (principle): When the belt with attached material passes through the lower roller, due to the action of the rolling ring, the contact area between the conveyor belt and the lower roller of the conveyor is reduced, which reduces the adhesion of the accessory on the roller ( adhesion) surface. When the conveyor belt with attachments passes, the adhesive force between the parts can fall off by the friction between the belts, and the attachments that are not compacted by the loading conveyor belt can be automatically separated in the subsequent operation, so that the belt can be effectively delete. Reduce the degree of attachment of accessories to the lower idler pulley.
