METHODS AND CONTROL SYSTEMS FOR PREVENTING TEARED BELT

Abstract

The present invention provides a belt tear prevention control method and system, the belt tear prevention control method includes: S1, obtaining a linear relationship between the load carried by the belt conveyor and the motor current; S2, setting a first current interval, a second current interval, and a third current interval in sequence; S3, when the motor current is within the first current range, maintain the material feeding speed at the starting end of the belt conveyor and continue the operation of the belt conveyor; S4, when the motor current is within the second current range, slow down the material feeding speed at the starting end of the belt conveyor and continue the operation of the belt conveyor; S5, when the motor current is within the third current range, stop the material transfer at the starting end of the belt conveyor and let the belt conveyor continue to run.The belt tear prevention control method provided in the present invention can avoid excessive load on the conveyor belt, effectively prevent belt tearing, and extend the service life of the belt.
