[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-2As shown, the slitting machine for PE film production in this embodiment includes a support plate 1, an unwinding roller 2 and a winding roller 3. A fixing frame 4 is fixedly installed above the middle of the support plate 1. A cutter shaft 5 is rotatably installed in the inner cavity of the fixing frame 4. A cutter 6 is fixedly installed on the outer wall of the cutter shaft 5. The cutters 6 are arranged in several groups at equal angles. The cutters 6 at the same angle have the same adjacent spacing along the axis of the cutter shaft 5, and the cutters 6 at different angles have different adjacent distances along the axis of the cutter shaft 5, which can be adjusted to different cutter 6 spacings. A driving mechanism 7 for rotating the cutter shaft 5 is also installed on the fixing frame 4. The driving mechanism 7 is used to rotate the cutter shaft 5, thereby changing the distance between the cutters 6.

[0022] Further, guide rollers 8 are also installed on the left and right sides of the fixed frame 4. The guide rollers 8 are used to guide the PE film.

[0023] Furthermore, the driving mechanism 7 is a motor.

[0024] Furthermore, the driving mechanism 7 is a rotating handle.

[0025] Furthermore, two winding rollers 3 are provided.

[0026] Working principle: When the spacing between different cutters 6 needs to be adjusted, the drive mechanism 7 drives the cutter shaft 5 to rotate and adjust. After the adjustment, the cutter shaft 5 no longer rotates freely. When the cutter shaft 5 rotates, the cutter 6 used to cut the PE film changes. Since the adjacent distances of the cutters 6 at different angles along the axis of the cutter shaft 5 are different, the adjacent spacing of the cutters 6 changes, thereby achieving the adjustment of the spacing between the cutters 6.
