[0028] The adjusting mechanism plays a key role in gap control during the operation of the device. By arranging a pressure sensor 201 between the card clothing 3 and the rear fixed cover plate 2, the contact pressure between the card clothing 3 and the cylinder 1 can be monitored in real time, and the data can be transmitted to the control panel of the carding machine. According to the pressure data, the operator can further accurately adjust the adjusting mechanism to ensure that the card clothing 3 and the cylinder 1 maintain appropriate contact pressure. When it is necessary to adjust the gap between the rear fixed cover plate 2 and the cylinder 1, the operator rotates the handle 502, which drives the fixed block 501 to rotate and move on the adjusting screw 5. Since the fixed block 501 is threadedly connected with the adjusting screw 5, the movement of the fixed block 501 will push the rear fixed cover plate 2 to slide along the guide rod 6, providing guidance for the movement of the rear fixed cover plate 2 and ensuring the stability and accuracy of the movement. At the same time, the compression spring 601 on the guide rod 6 plays a certain buffering and auxiliary resetting role. In this way, the gap between the rear fixed cover plate 2 and the cylinder 1 can be flexibly and accurately adjusted according to the process requirements of different fiber carding, reducing the friction between the card clothing 3 and avoiding rigid contact, thereby reducing the wear of the card clothing 3 and improving the carding effect.

[0029] In the embodiment one, the damping mechanism is further disclosed, and the specific structure is as follows: the outer wall of the rear fixed cover plate 2 is provided with a damping mechanism, the damping mechanism comprises a damping rod 8 fixedly installed on the outer wall of the rear fixed cover plate 2, and a buffer spring 7 is sleeved on the outer wall of the damping rod 8. The damping rod 8 is distributed at equal intervals on the outer wall of the rear fixed cover plate 2, and one end of the damping rod 8 is connected with the inner wall of the fixed plate 401. One end of the buffer spring 7 is attached to the outer wall of the rear fixed cover plate 2, and the other end of the buffer spring 7 is attached to the inner wall of the fixed plate 401.

[0030] The damping mechanism is mainly used to ensure the stability of the operation of the device. During the high-speed operation of the cylinder 1, vibration and impact force will be generated and transmitted to the rear fixed cover plate 2. At this time, the damping rod 8 and the buffer spring 7 work cooperatively to play a damping role. The damping rod 8 has damping characteristics and can consume vibration energy to reduce the vibration amplitude of the rear fixed cover plate 2. The buffer spring 7 is sleeved on the outer wall of the damping rod 8. When the rear fixed cover plate 2 is subjected to vibration impact, the buffer spring 7 will be compressed or stretched, absorbing part of the impact force through elastic deformation, converting kinetic energy into elastic potential energy. When the vibration impact force is weakened, the buffer spring 7 releases the elastic potential energy, so that the rear fixed cover plate 2 returns to a relatively stable position. The damping rod 8 and the buffer spring 7 cooperate with each other to effectively reduce the shaking of the rear fixed cover plate 2, reduce the friction and collision between the card clothing 3 and the cylinder 1, ensure the stability of the contact between the card clothing 3 and the cylinder 1, and further improve the stability of the operation of the equipment and the quality of fiber carding.
