[0048] Further, the first adjusting assembly 2 is quickly assembled by installing the first bolt 22 on the horizontal plate 21 through the first nut 23, when adjusting, the first bolt 22 is moved to the required position along the first mounting hole by unscrewing the first nut 23, and the first bolt 22 is fixed by screwing the first nut 23, so that the position of the upper contact block 24 can be quickly adjusted, and the friction torque generated by the friction pair interface between the output end of the first adjusting assembly 2 and the conveying belt can be controlled by adjusting the contact degree between the upper contact block 24 and the conveying belt.

[0049] In fact, the air cylinder or linear driving structure on the market can also achieve this effect and also belongs to the protection range of the utility model, but the present application has two advantages compared with the above device, the first advantage is that when the first bolt 22 or the upper contact block 24 at the bottom is damaged, it can be directly repaired by replacing the first bolt 22. The second advantage is that because the conveying belt has a large vibration amplitude during transportation, the first bolt 22 can well avoid the problem of sudden stop of the conveying belt caused by misjudgment.

[0055] To adjust the inclination of the lower correction unit 32, at least two adjusting modules are required to adjust the height and the connecting effect of the top end of the adjusting module and the bottom plate 321, so that the inclination can be adjusted. When adjusting, firstly, the inclination angle to be adjusted depends on the height difference between the two adjusting modules, so the adjustable angle range is large; secondly, the adjusting module is arranged on the two sides of the bottom of the bottom plate 321, which has high support stability for the bottom plate 321, and the size of the bottom plate 321 is not disturbed. Obviously, when supporting the conveying belt, the larger the contact surface with the conveying belt is, the better the effect is, which can meet the needs of the utility model.
