[0022] Embodiment 1

[0023] Please refer to Figures 1-3, the present utility model provides a technical solution: a photosensitive drum pressing device, including an overall frame 1 and a support column 2. A cylinder 3 is fixedly installed at the top of the overall frame 1, and an upper pressing table 4 is fixedly installed at the output end of the cylinder 3. A lower pressing table 5 is fixedly installed on the inner surface of the overall frame 1. Slide holes 6 are symmetrically formed through the top of the overall frame 1. Fixed blocks 7 are symmetrically fixedly installed on the outer wall of the upper pressing table 4. A cylinder 8 is fixedly installed at the top of the fixed block 7, a stop block 9 is fixedly installed at the top end of the cylinder 8, and a buffer spring 10 is sleeved on the outer wall of the cylinder 8. The upper pressing table 4 drives the fixed block 7 to fall together. During the falling process of the fixed block 7, the cylinder 8 will be driven to slide downward inside the slide hole 6. During the downward sliding process of the cylinder 8, the stop block 9 will be driven to move downward. During the downward movement of the stop block 9, the buffer spring 10 will be compressed. During the process of compressing the buffer spring 10, the buffering effect when the upper pressing table 4 falls can be achieved, thereby effectively avoiding the sudden fall of the cylinder 3 when it fails and loses pressure and injuring the operating personnel.

[0024] Please refer to Figures 1-3 , the cylinder 8 is slidably connected with the slide hole 6. The sliding connection improves the up-and-down adjustment effect of the cylinder 8. The top end of the buffer spring 10 is fixedly connected with the stop block 9, and the bottom end of the buffer spring 10 is fixedly connected with the overall frame 1. The fixed connection improves the use stability of the buffer spring 10. The number of the support columns 2 is four groups. The four groups of support columns 2 are located at the bottom of the overall frame 1. The four groups of support columns 2 are fixedly connected with the overall frame 1. The fixed connection improves the stability of the overall frame 1 during use. A bottom block 17 is fixedly installed at the bottom end of the support column 2. The bottom block 17 is in a frustum shape. The frustum-shaped bottom block 17 increases the contact area between the support column 2 and the ground, thereby improving the stability of the support column 2 during use.

[0025] Embodiment Two

[0026] Please refer to Figure 1 and Figure 4, a long shell 11 is fixedly installed on the inner surface of the overall frame 1. One end of the long shell 11 is fixedly installed with a driving motor 12. The output end of the driving motor 12 is fixedly installed with a bidirectional lead screw 13. The outer wall of the bidirectional lead screw 13 is symmetrically threadedly connected with L-shaped plates 14. One end of the L-shaped plate 14 is fixedly installed with a clamping ring 15. By starting the driving motor 12 to drive the bidirectional lead screw 13 to rotate, during the rotation of the bidirectional lead screw 13, it will drive two groups of L-shaped plates 14 to slide in the same direction inside the long shell 11. During the sliding process of the L-shaped plates 14, they will drive the clamping rings 15 to move together. After moving a certain distance, the two clamping rings 15 will clamp and fix the photosensitive drum to be pressed, thereby effectively avoiding the offset of the photosensitive drum during pressing and improving the pressing effect of the photosensitive drum. A protective pad 16 is fixedly installed on the inner wall of the clamping ring 15, which improves the protective effect when the clamping ring 15 clamps the photosensitive drum. The L-shaped plate 14 is slidably connected to the long shell 11, and the sliding connection improves the limiting effect during the adjustment of the L-shaped plate 14.

[0027] Working principle: When pressing, first vertically slide the assembled photosensitive drum into the lower pressing table 5. After sliding in, start the driving motor 12. The driving motor 12 drives the bidirectional lead screw 13 to rotate. During the rotation of the bidirectional lead screw 13, it will drive two groups of L-shaped plates 14 to slide in the same direction inside the long shell 11. During the sliding process of the L-shaped plates 14, they will drive the clamping rings 15 to move together. After moving a certain distance, the two clamping rings 15 will clamp and fix the photosensitive drum to be pressed, thereby effectively avoiding the offset of the photosensitive drum during pressing and improving the pressing effect of the photosensitive drum. After clamping and fixing, start the cylinder 3. When the cylinder 3 works, it will drive the upper pressing table 4 to move downward. After moving a certain distance, the upper pressing table 4 will cooperate with the lower pressing table 5 to press the photosensitive drum. When in the process of pressing, if the cylinder 3 fails and the upper pressing table 4 drops, the upper pressing table 4 can drive the fixed block 7 to drop together. During the dropping process of the fixed block 7, it will drive the cylinder 8 to slide downward inside the sliding hole 6. During the downward sliding process of the cylinder 8, it will drive the stopper 9 to move downward. During the downward movement of the stopper 9, it will squeeze the buffer spring 10. During the process of squeezing the buffer spring 10, the buffer effect when the upper pressing table 4 drops can be realized, thereby effectively avoiding the sudden dropping and injuring of the operating personnel when the cylinder 3 fails and loses pressure.
