[0002] Belt conveyors are widely used in industrial fields, such as docks, power plants, metallurgy, railways, stations, coal, grain, cement and other industries. They are important equipment for conveying bulk materials. Generally speaking, belt conveyors consist of a conveyor belt of a certain width and closed in a loop, multiple sets of rollers to support and position the conveyor belt, a power device to drive the conveyor belt, a bracket and other components. Among them, the smooth and reliable operation of the belt determines the operating state and power output efficiency of the conveyor.
