Abstract

A blade driving apparatus configured to drive a blade of a cutting device to cut a web and includes an anvil and a slide assembly. The slide assembly includes a slide rail and a slide block that are slidably connected to each other. The slide block is connected to the anvil, and the slide block and the anvil move back and forth relative to the slide rail along a travel direction of the web. At least one of the slide rail or the slide block is made of a non-metallic material.

First claim

What is claimed is:

1. A blade driving apparatus, comprising:
an anvil;
a slide assembly, comprising a slide rail and a slide block that are slidably connected to each other;
a connecting block connected to the anvil; and
a blade driving rod, the blade driving rod comprising an end connected to the connecting block;
wherein the slide block is connected to the anvil, and the slide block and the anvil move back and forth relative to the slide rail along a travel direction of a web.

2. The blade driving apparatus according to claim 1 , wherein at least one of the connecting block or the blade driving rod is made of a non-metallic material.

3. The blade driving apparatus according to claim 1 , wherein a connecting slot is provided at the connecting block and is configured to accommodate the end of the blade driving rod, and the connecting slot is in clearance fit with the end of the blade driving rod.

4. The blade driving apparatus according to claim 3 , wherein the clearance fit is such that a radial width of the end of the blade driving rod is less than a radial width of the connecting slot.

5. The blade driving apparatus according to claim 3 , wherein the connecting slot and the end of the blade driving rod are T-shaped.

6. The blade driving apparatus according to claim 1 , further comprising:
a cut drive assembly;
wherein the slide assembly is connected to the cut drive assembly, and is configured to be driven by the cut drive assembly to move back and forth along a direction perpendicular to the travel direction of the web.

7. The blade driving apparatus according to claim 6 , wherein the cut drive assembly comprises a cut drive motor and a cam follow-up structure that are connected to each other, and the cam follow-up structure is connected to the slide assembly.

8. The blade driving apparatus according to claim 1 , further comprising:
a follow-up drive assembly;
wherein the anvil is connected to the follow-up drive assembly, and is configured to be driven by the follow-up drive assembly to move back and forth along the travel direction of the web.

9. The blade driving apparatus according to claim 8 , wherein:
the anvil comprises a first connecting plate and a second connecting plate that are connected to each other;
the first connecting plate is further connected to the slide block and the connecting block; and
the second connecting plate is further connected to the follow-up drive assembly.

10. A cutting device, comprising:
a blade driving apparatus comprising:
an anvil;
a slide assembly, comprising a slide rail and a slide block that are slidably connected to each other;
a connecting block connected to the anvil; and
a blade driving rod, the blade driving rod comprising an end connected to the connecting block;
wherein the slide block is connected to the anvil, and the slide block and the anvil move back and forth relative to the slide rail along a travel direction of a web.

11. The cutting device according to claim 10 , wherein at least one of the connecting block or the blade driving rod is made of a non-metallic material.

12. The cutting device according to claim 10 , wherein a connecting slot is provided at the connecting block and is configured to accommodate the end of the blade driving rod, and the connecting slot is in clearance fit with the end of the blade driving rod.

13. The cutting device according to claim 12 , wherein the clearance fit is such that a radial width of the end of the blade driving rod is less than a radial width of the connecting slot.

14. The cutting device according to claim 12 , wherein the connecting slot and the end of the blade driving rod are T-shaped.

15. The cutting device according to claim 10 , wherein:
the blade driving apparatus further comprises a cut drive assembly; and
the slide assembly is connected to the cut drive assembly, and is configured to be driven by the cut drive assembly to move back and forth along a direction perpendicular to the travel direction of the web.

16. The cutting device according to claim 15 , wherein the cut drive assembly comprises a cut drive motor and a cam follow-up structure that are connected to each other, and the cam follow-up structure is connected to the slide assembly.

17. The cutting device according to claim 10 , wherein:
the blade driving apparatus further comprises a follow-up drive assembly; and
the anvil is connected to the follow-up drive assembly, and is configured to be driven by the follow-up drive assembly to move back and forth along the travel direction of the web.

18. The cutting device according to claim 17 , wherein:
the anvil comprises a first connecting plate and a second connecting plate that are connected to each other;
the first connecting plate is further connected to the slide block and the connecting block; and
the second connecting plate is further connected to the follow-up drive assembly.

19. A blade driving apparatus, comprising:
an anvil;
a slide assembly, comprising a slide rail and a slide block that are slidably connected to each other; and
a follow-up drive assembly;
wherein:
the slide block is connected to the anvil, and the slide block and the anvil move back and forth relative to the slide rail along a travel direction of a web; and
the anvil is connected to the follow-up drive assembly, and is configured to be driven by the follow-up drive assembly to move back and forth along the travel direction of the web.
