[0002] A rewinder is a widely used piece of equipment in the processing of materials such as paper, film, and mica tape. Its main function is to slit wide rolls of material for subsequent processing and use. During the operation of the rewinder, the slitting blades play a crucial role, determining the slitting effect and the quality of the roll material. In particular, the circular slitting blades of rewinders are widely used in slitting operations for various materials due to their sharpness, durability, high hardness, and good toughness.

[0003] However, there are some problems in the design of traditional rewinding machine slitting circular blades that urgently need to be solved. First, traditional circular blades are generally fixed by a slot in the center. While this method can fix the blade to a certain extent, it is prone to loosening due to vibration, wear, and other factors during long-term use, thus affecting the stability and accuracy of slitting. In addition, the traditional fixing method is cumbersome and inefficient when changing blades, making it difficult to meet the demands of modern production for high efficiency and convenience.

[0024] Reference Figure 1-4 This utility model provides a rewinding machine slitting circular blade, which includes a main rod 1. Multiple tightening plates 2 are fixedly connected to the upper end of the main rod 1. A second limiting post 14 is fixedly connected to the lower end of the main rod 1. A threaded post 13 is fixedly connected to the lower end of the second limiting post 14. An external arm 11 is fixedly connected to the upper end of the main rod 1, ensuring the overall strength of the blade.

[0025] Specifically: multiple first limiting blocks 12 are fixedly connected to the side of the external arm 11. The first limiting blocks 12 are movably connected to the tightening plate 2. The tightening plate 2 has a limiting groove 16. A second limiting block 17 is fixedly connected to the external arm 11. The second limiting block 17 is movably connected to the limiting groove 16, which enhances the connection stability between the external arm 11 and the tightening plate 2.

[0026] Specifically: a helical thread 3 is fixedly connected to the tightening plate 2, and a tightening ring 4 is movably connected to the tightening plate 2. A first threaded groove 15 is opened in the tightening ring 4, and the first threaded groove 15 is movably connected to the helical thread 3. A friction strip 5 is fixedly connected to the side of the tightening ring 4, so that the blade can cut the material more stably.

[0027] Specifically: The lower end of the main rod 1 is fixedly connected to multiple first limiting posts 7, and corresponding pressure springs 8 are movably connected to the first limiting posts 7. The lower end of the pressure springs 8 is fixedly connected to friction plates 9, and the friction plates 9 are movably connected to the second limiting posts 14 to prevent the circular slice 6 from shaking during the cutting process.

[0028] Specifically: A circular slice 6 is movably connected to the second limiting post 14, the circular slice 6 is movably connected to the friction plate 9, and the lower end of the friction plate 9 is fixedly connected to the first friction point 18.

[0029] Specifically: symmetrical second friction points 19 are fixedly connected to the circular slice 6, and the second friction points 19 are movably connected to the first friction point 18 to adapt to different cutting requirements.

[0030] Specifically: a fixed rotating block 10 is movably connected to the threaded column 13. The fixed rotating block 10 has a second threaded groove 20, which is movably connected to the threaded column 13. A first friction point 18 is fixedly connected to the upper end of the fixed rotating block 10, and the first friction point 18 is movably connected to the second friction point 19, which enhances the cutting stability and accuracy of the blade.

[0031] Working principle:

[0032] The core structure of the blade is supported by the main rod 1. The tightening plate 2, which is fixedly connected to the upper end of the main rod 1, is connected to the outer arm 11 through the movable connection of the first limiting block 12 and the second limiting block 17, and the cooperation of the limiting groove 16, forming a stable frame. This design not only enhances the overall strength of the blade, but also ensures the stability of the outer arm 11 under force, preventing cutting errors caused by vibration. The oblique thread 3 on the tightening plate 2 cooperates with the first threaded groove 15 in the tightening ring 4. By rotating the tightening ring 4, the tightening degree of the tightening plate 2 can be precisely adjusted. This allows for flexible adjustment of the blade's tightening state according to the different characteristics and thickness of the cutting material, thereby optimizing the cutting effect. The friction strip 5 on the side of the tightening ring 4 further enhances the friction between the blade and the material, making the cutting process more stable. A pressure spring 8 is movably connected to the first limiting post 7 at the lower end of the main rod 1. The friction plate 9 fixed at the lower end of the pressure spring 8 is movably connected to the second limiting post 14. The elasticity of the pressure spring 8 provides dynamic support and limitation for the circular slice 6, effectively preventing wobbling during high-speed rotation and cutting, thus improving cutting accuracy and stability. The second friction point 19 on the circular slice 6 is movably connected to the first friction point 18 at the lower end of the friction plate 9, enhancing the connection stability between the circular slice 6 and the friction plate 9. This allows the circular slice 6 to be finely adjusted during cutting according to the material's hardness and thickness to adapt to different cutting requirements. The symmetrical design of the second friction point 19 makes the circular slice 6 more evenly stressed, reducing wear and deformation caused by single-point stress. The fixed rotating block 10, fitted on the threaded post 13, is movably connected to the threaded post 13 via its second threaded groove 20, allowing for convenient adjustment of the fixed rotating block 10's position, thereby changing the contact state between the first friction point 18 and the second friction point 19. This allows for precise adjustment of the blade's cutting pressure and angle according to cutting requirements, further enhancing the blade's cutting stability and accuracy.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
