The mounting plate 1 is threadedly connected with a threaded rod 9. The threaded rod 9 is threadedly connected to the cutting knife 12 and the fixing plate 13. One end of the threaded rod 9 abuts against the mounting plate 1, and the other end of the threaded rod 9 passes through the fixing plate 13 and is threadedly connected with a nut 18. The nut 18 abuts against the fixing plate 13. At this time, the cutting knife 12 is clamped by the mounting plate 1 and the fixing plate 13, and the cutting knife 12 abuts against the fixed shaft 2. Multiple fixed rings 21 mean there are multiple cutting knives 12, which can realize the cutting of the cutting knives 12 at multiple stations to cut the material.

[0028] A limiting groove 20 is formed on the support rod 14. A threaded hole is formed on the fixed ring 21. An adjusting rod 19 is threadedly connected to the threaded hole. The adjusting rod 19 abuts tightly in the limiting groove 20. A scale line 22 is fixedly arranged on the support rod 14. The scale line 22 is above the limiting groove 20. When the adjusting rod 19 does not abut tightly against the limiting groove 20, the fixed ring 21 can move left and right on the support rod 14, that is, the position of the cutting knife 12 moves left and right. When the position of the cutting knife 12 is appropriate, the adjusting rod 19 is tightened by threading, so that the adjusting rod 19 abuts tightly against the limiting groove 20, the fixed ring 21 abuts tightly against the support rod 14, and the cutting knife 12 is fixed. The scale line 22 makes the adjustment distance of the cutting knife 12 more accurate.

[0029] The positioning structure 3 includes a fixed frame 5, a slider 6, a moving block 7 and a pressing rod 11. The fixed frame 5 is fixedly arranged on the support frame 4. There are two fixed frames 5 arranged on the support frame 4. The fixed shaft 2 is between the two fixed frames 5. The slider 6 is slidably arranged on the fixed frame 5.

The pressing rod 11 abuts tightly against one of the moving blocks 7 of the moving block 7. The moving block 7 abuts tightly against the slider 6. The slider 6 abuts tightly against the other moving block 7. At this time, the fixed shaft 2 is fixed on the fixed frame 5.

[0031] A connecting rod 23 is threadedly connected to the fixed rod 10. The connecting rod 23 is threadedly connected to the fixed frame 5. The connecting rod 23 makes the fixed rod 10 detachably arranged on the fixed frame 5, which is convenient to disassemble the moving block 7 and the slider 6 from the fixed frame 5. A pressing plate 8 is connected to the moving block 7. The pressing rod 11 abuts tightly against the pressing plate 8. The pressing plate 8 abuts tightly against the moving block 7. When the pressing plate 8 is used, the pressing rod 11 does not directly abut tightly against the moving block 7, so that the pressing rod 11 is not easy to scratch the moving block 7.

[0032] The fixing frame 5 is provided with adjustment slots 16. There are multiple adjustment slots 16 provided on the support frame 4. The support rod 14 is inserted into the adjustment slot 16. A limit hole 17 is provided in the adjustment slot 16. The support rod 14 is threadedly connected with a limit rod 24, and the limit rod 24 is threadedly connected in the limit hole 17. The adjustment slot 16 functions to facilitate the adjustment of the height of the support rod 14, and the limit rod 24 and the limit rod 24 function to fix the support rod 14 on the fixing frame 5.

[0033] The implementation principle of this embodiment is as follows: When adjusting the distance between the cutting knives 12, loosen the adjusting rod 19 by screwing, so that the adjusting rod 19 does not tightly abut against the limiting slot 20. At this time, the fixing ring 21 can move on the support rod 14. When the fixing ring 21 moves, the mounting block 15 and the cutting knife 12 also move accordingly. According to the scale line 22 on the support rod 14, after moving the distance between the cutting knives 12 to an appropriate position, then tighten the adjusting rod 19 by screwing. The adjusting rod 19 abuts against the limiting slot 20, and the fixing ring 21 abuts against the support rod 14. The fixing ring 21 is fixed, and the adjustment of the distance between the cutting knives 12 is completed, achieving the effect of being able to adjust the distance between the cutting knives 12 and being convenient to use.
