On the basis of fixation, the output end of the second drive motor 7 can drive the photosensitive drum to rotate between the first support block 6 and the second support block 901 through the second plug 17, and it is convenient to cooperate with the moving mechanism 5 to perform the cleaning operation on the photosensitive drum. After cleaning is completed, the output end of the fan 3 blows air through the blowing pipe 4, which can blow air to the photosensitive drum to quickly dry its cleaning liquid;

[0024] The moving mechanism 5 includes an assembly frame 505 and an electric push rod 504. The electric push rod 504 is symmetrically fixedly mounted on the back of the mounting frame 2. The output end of the electric push rod 504 is movable and penetrates the mounting frame 2 and the assembly frame 505 and is fixedly mounted. The inner side of the assembly frame 505 is rotatably connected to the first screw 502. One end of the assembly frame 505 is fixedly mounted with a first drive motor 501. One end of the first screw 502 penetrates the wall of the assembly frame 505 and is fixedly mounted with the output end of the first drive motor 501. The outer side of the first screw 502 is threadedly connected to a moving block 503. A connecting plate 506 is fixedly mounted on the outer side of the moving block 503. A sponge 507 is fixedly connected to the front of the connecting plate 506. A cleaning cloth 508 is fixedly connected to the side of the sponge 507 away from the connecting plate 506.
