Description

Technical Field

[0001] The utility model relates to the technical field of deviation rectifying devices, in particular to an adjustable full-automatic deviation rectifying device. Background Technique

[0002] An adjustable full-automatic deviation rectifying device is a device used for a belt conveyor. It can automatically detect the deviation during the operation of the belt and make adjustments to ensure that the belt is always on the predetermined operation track. This device usually includes sensors, controllers, and actuators, and can respond to the signal of the belt deviating from the center, and correct the running direction of the belt by adjusting the position of the deviation rectifying device.

[0003] When the deviation rectifying device is in use, dust will adhere to the outside of the deviation rectifying roller. If it is not cleaned in time, the dust will change the friction coefficient of the surface of the idler roller, resulting in a weakened deviation rectifying force and affecting the accuracy of deviation rectification. Therefore, an adjustable full-automatic deviation rectifying device is proposed. Content of the Utility Model
