[0002] A belt conveyor is a mechanical device that uses frictional drive during the continuous transportation of materials. It mainly consists of components such as a frame, a conveyor belt, idlers, drums, a tensioning device, and a transmission device. Belt conveyors are widely used in industrial production and can continuously transport materials from the initial feeding point to the final discharging point on a specific conveying line. Among them, idlers are an important part of belt conveyors and can be divided into upper idlers and lower idlers according to the installation position. The upper idlers are located at the top of the conveyor belt and are mainly used to support the conveyor belt and balance the weight of the materials; the lower idlers are located at the bottom of the conveyor belt and are used to support the conveyor belt and materials to ensure their smooth passage through the conveying system.
