[0027] Specifically, in actual use of this case, the two detachable tools 5 are distributed left and right along the tool shaft 4 and engage with each other. When the fixed block 503 contacts the other detachable tool 5, it is squeezed and compressed backwards, and the first spring 504 is squeezed. The pull rod 502 on the rear side of the fixed block 503 slides in the opening of the fixed box body 501. When the two detachable tools 5 are assembled, the fixed block 503 moves to the fixed hole 505, and the elastic force of the first spring 504 makes it rebound into the fixed hole 505 to complete the engagement. This design makes the detachable tool 5 easy to install and has a good fixing effect. When it needs to be replaced, it is removed using the disassembly component 8, which ensures the safety of operation and the convenience of tool replacement. The material is adjusted in tension by the tensioning roller 3 from the discharge roll 2 and then passed through the tool shaft 4, and is wound up by the receiving roll 6 through the cutting of the detachable tool 5.

[0028] Combination Figure 6-Figure 7The disassembly assembly 8 includes a disassembly box body 801 for fixing parts, a main gear 802 is slidably connected to the middle position of the disassembly box body 801, a push rod 803 is fixed on the top of the main gear 802 and passes through the top of the disassembly box body 801, a second spring 804 is fixed between the push rod 803 and the disassembly box body 801, and a meshing gear 805 is meshed on both sides of the main gear 802. The meshing gear 805 is rotatably connected to the inside of the disassembly box body 801, a toggle rod 806 is fixed on one side of the meshing gear 805, and a hook 8061 is fixed at the bottom of the toggle rod 806. The hook 8061 is inserted into the pull ring at one end of the pull rod 502 for use. When the detachable tool 5 needs to be disassembled, the two hooks 8061 are inserted into the pull ring at one end of the pull rod 502, and the index finger and the middle finger hold a lifting hook.

The push rod 803 is pressed down to compress the second spring 804, and the main gear 802 at the bottom of the push rod 803 is also compressed downward, and moves inside the disassembly box body 801, and the meshing gear 805 meshing with the main gear 802 rotates, driving the toggle rod 806 to rotate, and the bottom hook 8061 rotates accordingly, so that the pull ring on the pull rod 502 translates while sliding on the inner wall of the hook 8061, the pull rod 502 is pulled out, and the fixing block 503 on the top of the pull rod 502 is also pulled out of the fixing hole 505, and the disassembly between the two detachable knives 5 is completed by the upper and lower operations at the same time. The disassembly process is simple to operate and the components are universal, and all the detachable knives 5 on the knife shaft 4 can be disassembled.

[0029] Combination Figure 4-Figure 5 The surface of the fixing block 503 inserted into the fixing hole 505 is designed to be arc-shaped, and the hook 8061 is designed to be L-shaped. The side of the fixing block 503 inserted into the fixing hole 505 is designed to be arc-shaped, which is convenient for compressing the two detachable tools 5 when they are first spliced ​​together, thereby improving the smoothness of the fixing process. The hook 8061 is designed to be L-shaped, which makes it more convenient to move the pull rod 502 and provide support after removal. The detachable tool 5 can be hung on the hook 8061 without having to be taken separately.

[0030] A positioning protrusion 506 is provided on the inner side of the detachable tool 5, and a plurality of positioning holes 401 are symmetrically and evenly distributed on the surface of the tool shaft 4. The positioning protrusion 506 is inserted into the positioning hole 401 for positioning. A positioning protrusion 506 is provided on the inner side of the detachable tool 5, and is inserted into the shaft rod of the positioning hole 401 for positioning. After the two detachable tools 5 are engaged, this design can make the detachable tool 5 more stably fixed on the tool shaft 4, and a plurality of positioning holes 401 are locally distributed on the positioning hole 401, and the spacing of the detachable tool 5 can be adjusted according to production requirements to cut materials of different widths.
