The movable plate is tightly pressed between the pressing plate and the cross beam, and the pressure between the movable plate and the cross beam and between the movable plate and the pressing plate are increased, so that the friction force between the movable plate and the cross beam and between the movable plate and the pressing plate is increased, and the position of the conveyor belt is prevented from being changed after the conveyor belt is corrected.

Preferably, the outer end thread part of the hinge bolt is provided with two hinge nuts. One of the hinge nuts is screwed with the hinge bolt with proper force, so that the movable plate and the cross beam are fixed, and the movable plate can rotate around the hinge joint through the adjusting mechanism. The two hinged nuts are mutually screwed, so that a locking force can be generated, and the hinged nuts can be effectively prevented from being unexpectedly loosened.

Preferably, two opposite side surfaces between the head of the hinge bolt and the movable plate are respectively provided with a groove matched with the thrust bearing. The matched groove is arranged between the head of the hinge bolt and the movable plate and is used for accommodating the thrust bearing, and the hinge bolt has the following advantages: the height of the head of the bolt is reduced, so that the equipment is convenient to mount; preventing dust from entering the bearing.

The invention has the beneficial effects that: the structure is simple, the detection device does not need to be calibrated, and the manufacturing and maintenance costs are lower.
