Problems solved by technology

However, the permanent magnet deviation correction will affect the working effect due to the reduction of the permanent magnet magnetism. The electromagnetic deviation correction needs to be equipped with a magnetic force coil, which causes the structure to be complicated.

Abstract

The invention provides a device capable of automatically rectifying the deviation of the conveyer belt according to the deviation sensing signals. The device comprises: a deviation sensing device which can detect the deviation of the conveyer belt and send out the deviation signal; a processor which is connected with the deviation sensing device and can receive the deviation signal; a deviation rectification mechanism which is connected with the processor and adjusts the conveyer belt to the proper position according to the deviation signal under the control of the processor. The invention also discloses the automatic deviation rectifying method of the device. The rectifying device can carry out the quantitative detection for the deviation of the conveyer belt, convert the detected deviation into a real-time continuous deviation signal and automatically adjust the conveyer belt to the working position under the control of a controller, without need for stopping the conveyor, so as to improve the work efficiency and reliability of the conveyer greatly.

Description

technical field [0001] The invention generally relates to the field of automatic control, in particular to an automatic deviation correction device and method for a conveyor belt. Background technique [0002] The conveyor belt of the belt conveyor is both a traction object and a load-bearing component, supporting and conveying the load of bulk materials. It is widely used in the loading and unloading of bulk materials such as coal, ore, grain, and cement. When conveying materials, the deviation of the conveyor belt will be caused due to the eccentricity of the shafting of the conveyor roller, the offset of the blanking point, and uneven loading. The deviation of the conveyor belt may cause friction between the edge of the conveyor belt and the frame, which will affect its service life; or directly cause the occurrence of material spilling accidents. [0003] When a deviation accident occurs, the operation of the conveying system must be stopped, and the deviation of the co...
