[0018] A roll-shaped feeding roller damping structure, characterized in that it includes: a fixed component 1-1, a friction component 1-2, a screw 1-4 and an elastic component 1-3, the fixed component 1-1 and the friction component 1-2 are provided with screw holes matching the screw 1-4, the screw 1-4 connects the fixed component 1-1 and the friction component 1-2 together through the screw holes, a gap is left between the fixed component 1-1 and the friction component 1-2, and the elastic component 1-3 is connected to the gap for applying tension to the fixed component 1-1 and the friction component 1-2.

[0019] Among them, a screw hole is opened on the fixing component 1-1, and a threaded hole is also opened at the corresponding position of the friction component 1-2. The fixing component 1-1 and the friction component 1-2 are connected by a screw rod 1-4. After the connection, a certain gap is retained between the fixing component 1-1 and the friction component 1-2. The elastic component 1-3 is sleeved on the screw rod 1-4 and installed in the gap between the fixing component 1-1 and the friction component 1-2. After installation, the friction component 1-2 and the screw 1-4 can slide through the screw hole of the fixing component 1-1, and the elastic component 1-3 applies a tensioning force to the fixing component 1-1 and the friction component 1-2.

[0020] The damping mechanism is sleeved on the fixed shaft fixed to the roller mechanism, and the friction component 1-2 presses the side of the feeding roller. The pressure of the friction component 1-2 on the feeding roller is adjusted by pushing the fixed component 1-1 to adjust the compression amount of the elastic component 1-3, thereby adjusting the damping. After adjustment, the fixed component 1-1 is fixed to the fixed shaft of the roller mechanism by the handle screw. When the roller rotates, the axial pressure applied by the friction component 1-2 on the side of the roller is converted into friction force to finally achieve the effect of increasing damping.

[0021] Furthermore, the elastic component 1 - 3 is a compression spring.

[0022] Among them, in the utility model, springs with different compression sizes are used as elastic components 1-3 according to actual conditions.

[0023] Furthermore, the friction components 1-2 are friction plates with different friction coefficients.

[0024] Among them, in the utility model, friction plates with different friction coefficients are used according to actual conditions to achieve the effect of increasing damping and maintaining stability.

[0025] Beneficial effects of the utility model: Based on the original structure, the utility model adds an elastic component 1-3 between the fixed component 1-1 and the friction component 1-2, and uses the elastic component 1-3 to apply axial pressure to increase the friction between the structures, thereby increasing damping and providing feeding stability.
