[0033] One side of the top of the support block 106 is fixedly connected to the drive motor 108. The output end of the drive motor 108 passes through the support block 106 and is fixedly connected to the first roller 109. The outer side of the first roller 109 is closely connected to the belt body 110. Sensors 111 are symmetrically provided on the left and right ends of the belt body 110 close to the first roller 109. The bottom of the sensor 111 is fixedly connected to the workbench 101. One end of the sensor 111 is connected to a controller, which controls whether the cylinder 103 moves.

[0034] The end of the belt body 110 away from the first roller 109 is closely connected to the second roller 112. The front and rear ends of the second roller 112 are rotatably connected to the support block 106. The belt body 110 is installed on the surface of the second roller 112 and the first roller 109.

[0035] The fixing mechanism 2 includes a bracket 201, the bottom of which is fixedly connected to the workbench 101, a groove 202 is formed on one side of the top of the bracket 201, a clamping frame 203 is fixedly connected to the inside of the groove 202, a threaded sleeve 204 is fixedly connected to the top of the clamping frame 203, and a second bolt 205 is connected to the inner thread of the threaded sleeve 204.

When the belt body 110 is offset, the sensor 111 sends a signal to the controller, which starts the cylinder 103 through the controller. The piston rod of the cylinder 103 drives the slider 104 to slide on the outside of the guide rail 105, thereby fine-tuning the angle of the first roller 109 or the second roller 112. The belt body 110 can be reset to avoid the offset of the belt body 110 during operation. The scanning of the triangulated laser profiler 210 can detect whether there is any damage on the belt body 110.
