Background

The belt conveyor mainly comprises a driving roller, a driven roller and a conveying belt. The driving roller and the driven roller of the belt conveyor are respectively arranged at two sides of the belt conveyor, when the driving roller rotates, the surface of the driving roller and the inner side of the belt are rubbed with each other, and the friction force transmits power to the conveying belt; the driven roller plays a role of tensioning a belt, and when the conveying belt rotates, the inner side of the conveying belt and the surface of the driven roller are rubbed with each other, and the friction force transmits power to the driven roller.

The inner sides of the driving roller, the driven roller and the conveying belt are worn after working for a period of time, the surfaces become smooth, the friction force between the driving roller, the driven roller and the conveying belt is reduced, and the phenomenon that the conveying belt, the driving roller and the driven roller mutually slide easily occurs. In addition, the long-term action of the tension and friction causes the conveyor belt to elongate, so that the tension between the driving roller and the driven roller is reduced, and the conveyor belt is caused to slip.
