A spiral cutter with a vibration damping function provided in an embodiment of the present invention includes a spiral cutter shaft 10, a spiral cutter holder 11 provided on the spiral cutter shaft 10, and a spiral cutter 13 installed on the spiral cutter holder 11 through a spiral cutter cover 12. An elastic pad 14 is embedded between the spiral cutter cover 12 and the spiral cutter 13.

[0025] It should be noted that in the present utility model, the elastic pad 14 is preferably made of rubber. Specifically, for the paper towel folding machine, for the first time, a part of the knife pressing point between the spiral knife cover 12 and the spiral knife 13 is changed to the elastic pad 14, so that the spiral knife 13 can be pressed and the elasticity of the spiral knife 13 can be increased. The design principle is that the curved surface of the spiral knife cover 12 is produced based on the surface of the spiral knife 13, so that a part of the surface of the spiral knife cover 12 is suspended, and the elastic pad 14 is added to the suspended position, so that when the spiral knife 13 cuts paper, a part of the tool can be pressed, and the front end part can be padded with the elastic pad 14, so that the elasticity between the bottom knife and the spiral knife 13 can be increased during paper cutting, the vibration and noise can be reduced, and the service life of the tool can be effectively improved.

[0026] Please refer to Figure 1 and Figure 2 , in a preferred embodiment of the present application, the spiral knife cover 12 is of a segmented structure. Since the overall width is relatively large, the spiral knife cover 12 is likely to be deformed during the installation process, so the segmented structure is adopted, so that the deformation can be reduced during the installation process.

[0027] Please refer to Figure 1 and Figure 2 , in a preferred embodiment of the present application, an installation groove 1221 is provided on the contact surface between the spiral knife cover 12 and the spiral knife 13, and the elastic pad 14 is located in the installation groove 1221 for easy installation.

[0028] Please refer to Figure 1 , in a preferred embodiment of the present application, spiral ridges are provided on the surface of the spiral knife shaft 10, and the spiral knife holder 11 is installed on the spiral ridges through a plurality of bolts.

[0029] Please refer to Figure 1 and Figure 2 , in a preferred embodiment of the present application, one side of the spiral knife holder 11 is stepped, and sequentially includes a first installation surface, a second installation surface and a third installation surface;

[0030] The first installation surface is attached to the spiral ridge;

[0031] The position of the second installation surface corresponds to the position of the spiral knife cover 12, and the two are fixedly connected by a plurality of bolts;

[0032] The spiral knife 13 is installed between the third installation surface and the end of the spiral knife cover 12, and the other surface of the spiral knife 13 is flush with the second installation surface.

[0033] Please refer to Figure 1 and Figure 2, in a preferred embodiment of the present application, the spiral cutter cover 12 includes a connected mounting portion 121 and an extrusion portion 122;

[0034] The mounting portion 121 is fixedly connected to the second mounting surface through a plurality of bolts;

[0035] The mounting groove 1221 is located in the extrusion portion 133, and the elastic pad 14 presses against the spiral cutter 13.

[0036] Please refer to Figure 1 and Figure 2 , in a preferred embodiment of the present application, a clearance groove 1211 is provided on the surface of the mounting portion 121 close to the second mounting surface, so that there is a gap between the mounting portion 121 and the second mounting surface, which facilitates locking the two through bolts and nuts.

[0037] Please refer to Figure 1 and Figure 2 , in a preferred embodiment of the present application, a relief angle 111 is provided at the connection between the third mounting surface and the second mounting surface. Since the overall width of the cutter is large and it is a spiral surface, there will be unevenness at this contact position during processing. By providing this relief angle 111, the uneven position can be removed, so that when the spiral cutter 13 is installed, it abuts against the second mounting surface and its surface is flush with the second mounting surface.

[0038] It should be noted that the spiral cutter in the present application can be applied not only in the field of household paper and the tissue paper production line, but also on the equipment for non-woven fabric production.

[0039] In summary, in the present utility model, by providing the elastic pad 14, during paper cutting, the elastic force between the spiral cutter 13 and the bottom cutter can be increased, thereby reducing the vibration and noise during paper cutting, effectively improving the service life of the cutter, making the cutting smooth and more durable, and having the advantages of better adjustment of cutting and better matching with the equipment, better meeting the market demand.
