[0002] The belt conveyor is a continuous transportation machine with a belt that doubles as a traction mechanism and a load-bearing mechanism. The belt conveyor has the advantages of long transportation distance, large transportation capacity, high production efficiency, labor saving, high degree of automation, convenient installation, and low energy consumption. , less mechanical wear, easy maintenance and many other advantages. Belt deviation is one of the most common failures of belt conveyors. It is usually caused by the different weights of the goods transported on the belt, and due to long-term transportation, some belts Due to the deformation due to friction, the belt deviates from the track during operation, and the material is irregularly deflected to any side of the conveyor belt, which makes the gravity of the belt uneven, resulting in different tensions on both sides of the belt, resulting in belt deviation:

[0003] (1) The installation mechanism of the existing deviation correction device cannot change the bearing force of the idler roller during blanking;

[0004] (2) The deviation correction form of the deviation correction mechanism is too simple, and only when the transitional belt deviation is sensed by the radio and television sensor, the deviation can be corrected through the deviation correction device, and the damaged belt cannot be changed
