Analysis of the structural characteristics of the belt conveyor tensioning device

Analysis of the structural characteristics of the belt conveyor tensioning device The belt conveyor is mainly composed of belts, transmission devices, frames, rollers, rollers, and tensioning devices. The chain feeder is an auxiliary equipment in the mechanized storage and transportation system of lime production enterprises. Its main function is to continuously and uniformly feed processed or unprocessed materials from a certain equipment (hoppers, storage bins, etc.) The mesh belt of the dryer in the material receiving equipment or transportation machinery is a kind of machinery that uses static friction to transport materials in a continuous manner by friction drive. Because the platform of this machine needs to be used repeatedly, it is rarely used alone. Instead, it forms a horizontal or vertical circulation system with various special machines such as jacking translator and jacking indexer. Belt conveyor has the advantages of large conveying capacity, simple structure, convenient maintenance, standardized parts, etc. It is widely used in mining, metallurgy, coal and other industries to convey loose materials or finished items. According to the requirements of conveying technology, it can be conveyed by a single unit. It can also be composed of multiple units or combined with other conveying 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 powder, granular, and granular materials with a bulk density of less than 1.67/ton/m3. Small lumps of low-abrasive materials and bagged materials, such as coal, gravel, sand, cement, fertilizer, grain, etc. The temperature of the delivered material is less than 60°C. The captain and assembly form can be determined according to user requirements, and the drive can be an electric drum or a drive device with a drive frame. Logistics conveyor belt belt with traction parts The conveyor belt generally includes: traction parts, load-bearing members, driving devices, tensioning devices, redirecting devices and supports. The traction parts are used to transmit traction, which can be conveyor belts, traction chains or wire ropes; the load-bearing components are used to carry materials, including hoppers, brackets or spreaders, etc.; the driving device powers the conveyor, usually by electric motors, reducers and Brake (stop) and other components; the tensioning device generally has two types of screw type and heavy hammer type, which can maintain a certain tension of the traction part. In addition to pure material transportation, it can also meet the requirements of the production process of various industrial enterprises. Rhythmic running of water transport lines. The transmission device, brake device and tension device are the core components of the belt conveyor, and its manufacturing process is the key to the production of the belt conveyor. In the production of belt conveyors, the tensioning device of the conveyor accessories can be designed according to the needs of users. The tension device roughly undergoes three stages: mechanical tension, semi-automatic tension and automatic tension. Mechanical tension mainly includes two tension modes: fixed winch tension and heavy hammer tension. The tension of the fixed winch can only be adjusted manually, and the constant tension of the conveyor belt cannot be guaranteed. The hammer tension response is slow and the cost is low. Semi-automatic tensioning mainly refers to the hydraulic hoisting tensioning device, which can basically realize the constant tension of the conveyor belt, at the same time, the corresponding speed is faster, the cost is lower, but it also has the characteristics of high energy consumption, serious equipment wear, and high failure rate. . Attraction rate; fully automatic tension mainly refers to hydraulic pressure. The automatic tension control device determines a reasonable tension control model according to the requirements of different belt tensions during the start-up phase and the normal and stable operation phase of the belt conveyor, and uses electronic control to realize the automatic tension control of the belt conveyor. The mechanical-hydraulic integration technology realizes the tension of the belt conveyor during the start, braking and stable operation phases. Stable, greatly increasing the life cycle of the conveyor belt. The belt conveyor accessory tensioning device is an important part. The tensioning device can be used to ensure that the drive roller in the belt conveyor has sufficient tension from this point to prevent the conveyor belt from slipping, and can also compensate the conveyor belt. The plastic deformation generated in the case of overwork maintains the small pulling force required for the normal operation of the conveyor, thereby ensuring the normal operation of the belt conveyor. The performance of the tensioning device directly affects the overall performance of the belt conveyor, which is also particularly important in the belt loading conveyor.
