The rotation connection between the feeding roller 2 and the receiving roller 4 can be realized by a bearing or a sliding bearing, and such an assembly method can ensure the stability of the feeding roller 2 and the receiving roller 4 during rotation and reduce wear, thereby extending the service life. A rotating rod 6 is rotatably connected to the surface of the frame 1, a worm wheel 7 is fixedly installed on one end of the rotating rod 6, a mounting block 8 is fixedly installed on the surface of the frame 1, a worm 9 is rotatably connected to the side of the mounting block 8, and the worm wheel 7 and the worm 9 are meshed. The meshing between the worm wheel 7 and the worm 9 provides accurate and stable rotational force transmission, thereby achieving precise cutting depth adjustment.

[0026] See also Figure 1-5, the surface of the frame 1 is provided with an annular groove 10, the inner wall of the annular groove 10 is slidably connected with a slider 11, and a top block 12 is fixedly installed at one end of the slider 11. The sliding connection between the slider 11 and the annular groove 10 can be a linear guide or a ball screw, etc., such a design can ensure the smooth movement and precise positioning of the top block 12 when adjusting the cutting depth. A screw rod 13 is provided through the surface of the top block 12, and a thread is provided inside the top block 12, and the thread is meshed with the screw rod 13, and a pressure block 14 is fixedly installed at one end of the screw rod 13.

[0027] Embodiment 2

[0028] See also Figure 4-5 The surface of the rotating rod 6 is provided with a slitting mechanism, and the slitting mechanism includes a fixed disk 18, and the fixed disk 18 is fixedly mounted on the surface of the rotating rod 6. The fixed disk 18 can be fixed to the rotating rod 6 by bolting or welding. Such a fixing method ensures the stability and reliability of the fixed disk 18 when rotating at high speed. The surface of the fixed disk 18 is fixedly mounted with a heat sink 19 and a cutter 20, and the heat sink 19 is arranged at equal distances on the surface of the fixed disk 18. The material of the heat sink 19 can be selected from aluminum alloy or copper. These materials have good thermal conductivity and can effectively and quickly conduct the heat generated by the cutter 20 to the heat sink 19, and dissipate the heat through the air, thereby maintaining a suitable working temperature of the cutter 20 and avoiding damage to the plastic film body 5 due to overheating.

[0029] Working principle: the plastic film body 5 is placed on the unwinding roller 2, and then the plastic film body 5 is rolled up by the receiving roller 4. During the rolling process of the plastic film body 5, it can be cut by the cutter 20, so as to cut the plastic film body 5. When adjusting the cutting angle of the cutter 20 to adapt to the plastic film body 5 of other thicknesses, the staff only needs to twist the worm 9, and the worm 9 then drives the worm wheel 7 meshing with it to rotate, and the worm wheel 7 then drives the rotating rod 6 to rotate, and the rotating rod 6 then drives the cutter 20 to move. At this time, the cutting depth of the cutter 20 can be adjusted, and when the worm wheel 7 rotates, the worm wheel 7 can synchronously drive the limit rod 15 to move. The limit rod 15 can squeeze the top block 12 to move, and the top block 12 slides in the annular groove 10 through the slider 11. When the required cutting depth is adjusted, the staff can twist the screw rod 13. At this time, since the top block 12 is provided with a thread, the screw rod 13 moves in the top block 12, and the screw rod 13 then drives the pressure block 14 to move until the pressure block 14 is tightly against the friction plate 16. At this time, the friction force generated by the friction plate 16 can fix the top block 12, and the groove 17 can further increase the friction force and further fix the position of the top block 12. In this way, the current cutting depth can be memorized, and during maintenance or other When the cutter 20 is offset due to his operation, the staff only needs to keep rotating the worm 9 until the worm wheel 7 drives the limit rod 15 to abut against the top block 12. At this time, the limit rod 15 is blocked by the top block 12, and the worm 9 cannot be rotated. At this time, the cutter 20 is located at the memorized position. The utility model can quickly and accurately adjust the cutting depth and angle of the cutter 20 to adapt to plastic films of different thicknesses by using the mechanism of the worm wheel 7 and the worm 9, and the coordinated use of the top block 12 and the limit rod 15, without the need for cumbersome manual adjustment process, and through the built-in memory function, that is, using the friction plate 16 and the pressure block 14 to fix the position of the top block 12, to ensure Even after mechanical maintenance or other intervention operations, the cutting depth and angle set before can be quickly restored. The set cutter 20 can cut the plastic film body 5, and the heat generated by the cutter 20 during continuous cutting can be conducted to the fixed disk 18, and then conducted to the heat sink 19 through the fixed disk 18, and then the heat can be dissipated through the heat sink 19. The temperature of the cutter 20 can be controlled by the heat sink 19 to avoid the plastic film body 5 from melting due to excessive temperature and causing adhesion. The utility model avoids melting or adhesion of the plastic film due to excessive temperature by effectively controlling the temperature of the cutter 20.
