With this structure, the electric cylinder 27 can push the clamping block 24 to clamp the base tube 1 to be processed, ensuring the stability of the base tube 1 to be processed during the processing. The toothed ring 23 can drive the base tube 1 to be processed clamped inside the toothed ring 23 to rotate during the rotation process, so that the base tube 1 to be processed contacts the grinding sand belt 8 during the rotation process for grinding, realizing the removal of the annular coating on the surface of the base tube 1 to be processed. A plurality of through-holes are provided on the limit frame 21. The toothed ring 23 is rotatably connected to the inner wall of the through-hole. The clamping block 24 is movably connected to the inside of the toothed ring 23. The base tube 1 to be processed is clamped inside the clamping block 24.

One end of the baffle 13 is fixed to the inner wall of the opening of the collection box 12 by glue, and the other end is used for opening and closing. The dust collected inside the collection box 12 can be conveniently collected by separating the collection box 12 from the drive box 9.

[0027] Working principle: When using the edge coating removal device for the surface of the photosensitive drum base tube, first insert the base tube 1 to be processed from one side of the limit frame 21, so that one side of the base tube 1 to be processed is inserted into the processing box 6 and is in contact with the grinding sand belt 8 inside the processing box 6. After observing through the visual window 4 that the base tube 1 to be processed is inserted to an appropriate depth, the electric cylinder 27 is started. The electric cylinder 27 pushes the clamping block 24 to clamp the outer wall of the base tube 1 to be processed. Subsequently, the first motor 3 drives the grinding sand belt 8 to rotate to grind the outer wall of one end of the base tube 1 to be processed. At the same time, the second motor 22 drives the gear 26 to rotate. During the rotation of the gear 26, the base tube 1 clamped inside the toothed ring 23 is pushed to rotate through the toothed ring 23, thereby ensuring the uniformity of the grinding of the outer wall of the base tube 1 to be processed. During the grinding process, the dust is sucked into the collection box 12 for collection under the operation of the negative pressure fan 10. When the negative pressure fan 10 is turned off, the baffle 13 intercepts the opening of the collection box 12 to prevent the dust from escaping.
