[0022] Specifically, before adjusting the position of the roller 6 during rotation, the roller 6 is first placed on the inner side of the multiple C-shaped brackets 1, and then the multiple flexible support parts 5 are driven by the driving part to move toward the center of the inner side of the C-shaped bracket 1, so that the wear-resistant blocks 51, springs 52 and dampers 53 on one side of the support plate 50 move toward the outer side of the roller 6, so that the multiple wear-resistant blocks 51 can tightly contact the outer side of the roller 6, increase the contact area between the multiple wear-resistant blocks 51 and the outer side of the roller 6, so that the multiple wear-resistant blocks 51 can effectively limit the roller 6 and avoid derailment during the process of rotating and adjusting the position of the roller 6. When processing the roller 6, the roller 6 can also be buffered by the damper 53 to avoid shaking during the processing of the roller 6, and the buffering effect is further improved by the cooperation of the damper 53.

[0023] Among them, two groups of flexible support parts 5 are provided on each group of C-shaped brackets 1, and the driving part is used to drive the two groups of support plates to move toward or away from each other. The driving part includes a fixed shell 7, a driving motor 72, a threaded rod 73 and two nut blocks 74. The fixed shell 7 is fixedly connected to the side of the C-shaped bracket 1 away from the notch 100, and the driving motor 72 is fixedly installed on one side of the inner wall of the fixed shell 7. One end of the threaded rod 73 is connected to the output shaft of the driving motor, and the other end is rotatably connected to the other side of the inner wall of the fixed shell.
