When the cutting knife 18 cuts the PET tape, the cutting knife 18 can be placed inside the cutting groove 19. In this step, when the PET tape needs to be cut, the pressure rod 13 can be used to squeeze and fix the PET tape to be cut, so that it can be more stable when the cutting knife 18 is used to cut it, reducing the possibility of damage caused by sliding of the PET tape when the PET tape is cut.
[0026] like Figure 2-4 As shown, a torsion spring 2 is fixedly connected to the middle part of the support cover 11; a top plate 21 is hingedly connected to the middle part of the torsion spring 2; a support rod 22 is fixedly connected to the middle part of the support cover 11; the end of the support rod 22 is slidably connected to the top plate 21; a second gear 23 is rotatably connected to the middle part of the support cover 11; a rotating wheel 24 is fixedly connected to the end of the second gear 23; during operation, when the PET belt is cut, the PET belt can be placed in the middle of the multiple sets of rotating wheels 24, and then the second gear 23 can be rotated when the PET belt is pulled, and when the second gear 23 rotates, the top plate 21 can swing downward under the action of the torsion spring 2, and when the PET belt needs to be cut, the support rod 22 can be used to support the top plate 21, and then the second gear 23 can be fixed by the top plate 21. In this step, when the PET belt needs to be cut, the rotating wheel 24 can be used to fix the PET belt to be cut, thereby reducing the sliding of the PET belt during the cutting process, and then the PET belt can be protected and the damage can be reduced.
[0027] like Figure 1-6As shown, multiple groups of cross plates 3 are fixedly connected to the middle part of the chassis 1; a disc 31 is rotatably connected to the middle part of the cross plate 3; a tension rod 32 is fixedly connected to the middle part of the disc 31; a rotating rod 33 is fixedly connected to the middle part of the disc 31; a hand rod 34 is slidably connected to the middle part of the rotating rod 33; a plug hole 35 is opened in the middle part of the support cover 11; the hand rod 34 is slidably connected to the plug hole 35; during operation, when the PET tape needs to be rolled up, the end of the PET tape can be placed in the middle part of the rotating rod 33 for fixing, and then the hand rod 34 can be pulled out from the middle part of the plug hole 35, and then the hand rod 34 can be rotated, so that the tension rod 32 can be rotated, and then the PET tape can be rolled up. This step can be used to quickly roll up the PET tape after the PET tape is cut, thereby reducing the excessive accumulation of the PET tape in the middle part of the chassis 1, thereby improving the efficiency of the PET tape production.
[0028] like Figure 1 As shown, a baffle 4 is fixedly connected to the middle of the chassis 1; a slide pad 41 is fixedly connected to the middle of the baffle 4; the slide pad 41 is fixedly connected to the chassis 1; during operation, when the PET belt needs to be cut, the PET belt can be placed in the middle of the slide pad 41, and then the baffle 4 is used to fix and limit the side of the PET belt, and then the PET belt can be cut. This step can reduce the movement of the PET belt when the PET belt needs to be cut, thereby improving the stability of the PET belt when it is cut, and thereby reducing the damage of the PET belt when it is cut.
[0029] like Figure 2-5 As shown, a plurality of groups of springs 5 are fixedly connected to the middle of the cutting groove 19; a buffer pad 51 is fixedly connected to the end of the spring 5; the buffer pad 51 is slidably connected to the cutting knife 18; during operation, when the cutting knife 18 is used to cut the PET tape, the end of the cutting knife 18 can be brought into contact with the buffer pad 51, and then the buffer pad 51 can be buffered by the action of the plurality of groups of springs 5.

In this step, when the PET tape needs to be cut, the pressure rod 13 can be used to squeeze and fix the PET tape to be cut, so that it can be more stable when the cutting knife 18 is used to cut it, reducing the PET tape from being cut when the PET tape is cut. In order to prevent the PET tape from slipping and causing damage, when the PET tape is cut, the PET tape can be placed in the middle of the multiple groups of rotating wheels 24, and then the second gear 23 can be rotated when the PET tape is pulled. When the second gear 23 rotates, the top plate 21 can swing downward under the action of the torsion spring 2. When the PET tape needs to be cut, the support rod 22 can be used to support the top plate 21, and then the second gear 23 can be fixed by the top plate 21. In this step, when the PET tape needs to be cut, the rotating wheel 24 can be used to fix the PET tape to be cut, thereby reducing the slippage of the PET tape during the cutting process, thereby protecting the PET tape and reducing the damage. When winding, the end of the PET tape can be placed in the middle of the rotating rod 33 for fixing, and then the hand rod 34 can be pulled out from the middle of the insertion hole 35, and then the hand rod 34 can be rotated, so that the tension rod 32 can be rotated, and then the PET tape can be wound up. This step can be used to quickly wind up the PET tape after the PET tape is cut, thereby reducing the excessive accumulation of the PET tape in the middle of the chassis 1, thereby improving the efficiency of the PET tape production. When the PET tape needs to be cut, the PET tape can be placed in the middle of the sliding pad 41, and then the baffle 4 can be used to fix and limit the side of the PET tape, and then the PET tape can be cut. This step can be used to reduce the need to cut the PET tape. The PET tape moves, thereby improving the stability of the PET tape when being cut, thereby reducing the damage to the PET tape during the cutting process. When the cutting knife 18 is used to cut the PET tape, the end of the cutting knife 18 can be brought into contact with the buffer pad 51, and then the buffer pad 51 can be buffered by the action of multiple sets of springs 5. This step can reduce the strong collision between the end of the cutting knife 18 and the cutting groove 19 when the cutting knife 18 is used to cut the PET tape, thereby protecting the end of the cutting knife 18 and reducing the damage to the cutting knife 18. When the PET tape is cut, the chassis 1 can be fixed to the workbench by the action of the convex pad 6, and then the triangular surface 61 can be used toThe PET belt can be protected when it is placed in the middle of the chassis 1. This step can make the chassis 1 more stable when the PET belt is cut, and reduce the situation that the chassis 1 shakes during the cutting process and causes the PET belt to be damaged. When pulling the hand lever 34, the clamp ring 7 can be used to limit the hand lever 34. This step can reduce the situation that the hand lever 34 falls off from the middle of the rotating rod 33 when the hand lever 34 is used to rotate the rotating rod 33.
