[0036] 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.

[0038] Reference Figure 1 - Figure 6 The top of the base 1 is fixedly connected to the slitting table 7, which provides a fixed support for the slitting table 7 through the top of the base 1. A groove 15 is opened at the top of the slitting table 7, so that the blade 13 can be plugged into the inner wall of the slitting table 7. The inner wall of the groove 15 is slidably connected to the bottom end of the blade 13, so that the blade 13 can reduce the contact area with the film material, reduce the cutting resistance, and make the cutting smoother and easier.

[0039] Reference Figure 1 - Figure 5 The outer wall of the lower pressing frame 6 is hinged with an articulated rod 11, so that the articulated rod 11 can perform a circular motion along the outer wall of the lower pressing frame 6. The bottom end of the articulated rod 11 is rotatably connected to a roller 8, so that the roller 8 can rotate along the bottom end of the articulated rod 11. The outer wall of the roller 8 is in contact with the top of the slitting table 7, so that when the roller 8 contacts the top of the slitting table 7, it can drive the articulated rod 11 to perform a circular motion.

[0040] Reference Figure 4 The outer wall of the lower pressing frame 6 is fixedly connected with a positioning block 12, and the outer wall of the lower pressing frame 6 provides a fixed support effect for the positioning block 12. The outer wall of the positioning block 12 is in contact with the outer wall of the hinged rod 11, so that the hinged rod 11 always maintains an inclined effect, and the roller 8 can always move in the specified direction when driving the hinged rod 11 to perform a circular motion.

[0041] Reference Figure 1 - Figure 2 , Figure 6The top of the base 1 is fixedly connected to a first roller group 4, which provides a fixed support for the first roller group 4 through the top of the base 1, so that the polymer film can be transported to the middle of the third roller group 16 through the first roller group 4. The top of the base 1 is fixedly connected to a second roller group 5, and the top of the base 1 is fixedly connected to a third roller group 16, so that the polymer film can be transported to the slitting table 7 through the two groups of roller groups.

[0042] Reference Figure 5 One end of the spring 14 is fixedly connected to the inner wall of the pressing frame 6, and the other end of the spring 14 is fixedly connected to the bottom end of the fixing plate 9, so that when the pressing frame 6 stops pressing down on the top of the cutting table 7, it can move downward by the elastic force of the spring 14.

[0043] Reference Figure 1 - Figure 5 There are two groups of rollers 8, so that the two groups of rollers 8 can stretch the polymer film at the top of the slitting table 7 outward, so that the polymer film can maintain a flat effect when being fixed by the pressing frame 6. There are four groups of columns 10, so that the pressing frame 6 can have a more stable effect when pressing down and rebounding.

[0044] Reference Figure 1 - Figure 6 The first roller group 4, the second roller group 5 and the third roller group 16 are all composed of two groups of rollers, so that the polymer film can be transported by the three groups of rollers through the middle of the two groups of rollers. The top of the column 10 is fixedly connected with a positioning ring 17, so that when the fixed plate 9 moves upward, it can drive the lower pressure frame 6 to move together.

[0045] Working principle: When using the device, first wrap the polymer film around the first roller group 4, and then pass one end of the polymer film between the second roller group 5 and the third roller group 16, so that the polymer film is flat on the top of the slitting table 7, and then start the telescopic motor 3 to drive the fixed plate 9 and the lower pressing frame 6 to move downward. During the pressing process, the two groups of rollers 8 first contact the top of the polymer film, and then due to the squeezing of the lower pressing frame 6, the two groups of rollers 8 are expanded outward, and while the rollers 8 are expanded outward, the wrinkled parts of the polymer film will be flattened, and then the bottom of the lower pressing frame 6 will be pressed down. It will contact with the top of the polymer film, so that the lower pressure frame 6 fixes the polymer film. At this time, the position that needs to be cut will be in a taut state, and then the fixed plate 9 will drive the blade 13 to extend along the bottom end of the lower pressure frame 6 to cut the polymer film, and then start the telescopic motor 3 again to drive the fixed plate 9 to move upward. When it moves to a certain position, it will contact with the positioning ring 17 at the top of the column 10, so that it drives the lower pressure frame 6 to move upward, so that it releases the fixation of the polymer film, and then rotate the second roller group 5 to bring out the cut polymer film.
