The processing seat 1 is set to ensure that it can be stably placed on the platform for use during use. At the same time, the limiting roller group 2 is fixedly installed in the middle of the processing seat 1, so that the plastic film can be stably clamped and limited by the limiting roller group 2 during the slitting process. The winding component 3 and the slitting seat 4 are respectively fixedly installed at both ends of the processing seat 1, so that the plastic film can be wound up by the winding component 3 during use, and the slitting knife group 6 is installed through the slitting seat 4. In this way, the slitting process can be carried out evenly during the process of winding and dragging the plastic film, and the position of the slitting knife group 6 on the slitting seat 4 can be changed during installation to achieve different slitting widths. After adjusting the position of the slitting knife group 6, it can be locked with the slitting seat 4 through the locking component 7 to ensure the stability of the slitting knife group 6 during processing.

[0029] Reference Figure 1 As shown, the limiting roller group 2 includes a support plate 21, an upper limit roller 22, and a lower limit roller 23. There are two support plates 21, and the two support plates 21 are fixedly mounted at both ends of the processing seat 1. The upper limit roller 22 is arranged directly above the lower limit roller 23, and both the upper limit roller 22 and the lower limit roller 23 are rotatably mounted between the two support plates 21. The structural setting of the limiting roller group 2 ensures that the upper limit roller 22 and the lower limit roller 23 can be installed through the support plate 21 during use. In this way, the plastic film can pass between the upper limit roller 22 and the lower limit roller 23 during processing, thereby achieving better limiting use of the plastic.

[0030] Reference Figure 2As shown, the frame 31 includes a main frame 311 and a mounting shaft 312. The main frame 311 is fixedly mounted on the upper end surface of the processing base 1, and the mounting shaft 312 is rotatably mounted on the head of the main frame 311. The winding frame 32 includes a sleeve 321 and a limit plate 322. The limit plates 322 are mounted on both ends of the sleeve 321 and are fixedly connected to the sleeve 321.

This ensures that the winding frame 32 can be stably mounted on the mounting shaft 312 through the sleeve 321 during installation, thereby achieving stable winding of the plastic film for use. By arranging limit plates 322 at both ends of the sleeve 321, it is ensured that the plastic film installed on the sleeve 321 is limited by the limit plates 322, and when in use, the position of the adjustment component 5 on the sleeve 321 can be changed according to the width of the plastic film. In this way, the two ends of the plastic film can be limited by the adjustment component 5 and the limit plates 312, and then the plastic films of different widths can be limited when they are rolled up.

[0031] Reference Figure 1 As shown, the slitting seat 4 includes a right-angle plate 41 and a scale plate 42. The right-angle plate 41 is fixedly mounted on the upper end surface of the processing seat 1. The scale plate 42 is horizontally arranged at the head of the right-angle plate 41, and the scale plate 42 is horizontally arranged on the upper end surface of the right-angle plate 41. The middle part of the scale plate 42 is provided with a slide 421 for installing the slitting knife group 6. By setting the structure of the slitting seat 4, it is ensured that the scale plate 42 can be supported and installed by the right-angle plate 41 when in use, so that the slitting knife group 6 can be installed through the scale plate 42. It is ensured that the corresponding number of slitting knife groups 6 can be installed in the slide 421 according to the actual slitting width and quantity when in use, and then the distance between the slitting knife groups 6 can be adjusted. The position of the slitting knife group 6 can be quickly determined by the scale on the scale plate 42, which is very convenient when installed.

[0032] Reference Figure 3 As shown, the adjustment assembly 5 includes an annular plate 51, a side block 52, and a locking bolt 53. The side block 52 is symmetrically mounted on one side of the annular plate 51, and the locking bolt 53 is mounted in the side block 52.

The structural arrangement of the adjustment assembly 5 ensures that when in use, the annular plate 51 can be sleeved on the sleeve 321 to limit the position of the rolled plastic film. The arrangement of the side block 52 and the locking bolt 53 ensures that the annular plate 51 can be rotated to lock after the position is adjusted.

[0033] Reference Figure 4 and Figure 5As shown, the slitting knife assembly 6 includes a movable shell 61, an indicator plate 62, and a splitting knife 63. The movable shell 61 is slidably mounted in the slide groove 421, the indicator plate 62 is fixedly mounted on the upper end surface of the movable shell 61, and the splitting knife 63 is fixedly mounted on the upper end surface of the indicator plate 62. The structural setting of the slitting knife assembly 6 ensures that the indicator plate 62 can be installed through the movable shell 61 during use. It ensures that the indicator plate 62 can be aligned with the scale on the scale plate 42 during installation, making it convenient to quickly determine the position of the slitting knife assembly 6. By fixing the splitting knife 63 on the indicator plate 62, the splitting knife 63 can be used to perform the slitting operation during the plastic film winding process. The locking assembly 7 includes a lifting frame 71 and a support spring 72. The lifting frame 71 is slidably mounted in the movable shell 61, and the support spring 72 is fixedly mounted between the lifting frame 71 and the movable shell 61. The structure of the locking assembly 7 is set to ensure that it can be slidably installed in the movable shell 61 through the lifting frame 71 when in use, and the head extends from the movable shell 61 to contact the lower end surface of the scale plate 42. In this way, when there is no external force, it can be stably supported on the scale plate 42 and locked under the action of the support spring 72, ensuring that the slitting knife group 6 will not slide during the cutting process.

[0034] In this embodiment, before the slitting process, the distance between the annular plate 51 and the limiting plate 322 is first slidably adjusted according to the width of the plastic film to be processed, ensuring that the distance between the two is exactly the same as the width of the plastic film, so as to ensure that there is no deviation during the winding process. After the position of the annular plate 51 is adjusted, it can be locked by the locking bolt 53. Then, according to the number and width of the plastic film to be cut, the appropriate number of slitting knife groups 6 are installed. After the slitting knife groups 6 are sequentially installed in the chute 421, the distance and installation position between them can be adjusted according to the scale. After the position of the slitting knife groups 6 is adjusted, the slitting process can be carried out. During the actual processing, the plastic film is passed between the upper limit roller 22 and the lower limit roller 23, and then wound on the sleeve 321 of the winding frame 32, and the segmentation knife 63 on the slitting knife group 6 is passed through the plastic film. Finally, the plastic film can be wound by rotating the winding assembly 3 to achieve a stable slitting operation.
