[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0021] Embodiment 1:

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a special cutting device for films, including: two U-shaped frames 1 and two support columns 5;

[0023] The bottoms of the two U-shaped frames 1 are installed on the front and rear sides of the upper surface of the bottom plate 2. Pulley wheels 3 are rotatably installed at the four corners between the two U-shaped frames 1 through rotating shafts. The four pulley wheels 3 are connected by a transmission belt 4. A driving motor is arranged at the rear side of one of the U-shaped frames 1. The output shaft of the driving motor is connected to the rotating shaft of one of the pulley wheels 3. The support columns 5 are arranged at the middle parts of the front and rear sides of the upper surface of the bottom plate 2. A cutting assembly is rotatably connected to the upper side between the two support columns 5 through a rotating shaft. The lower surface of the cutting assembly is in contact with the upper surface of the transmission belt 4.

[0024] Analysis of the above content: When in use, the film substrate to be cut is placed on the transmission belt 4 from the left. As the transmission belt 4 moves leftward, when the film substrate comes into contact with the cutting assembly, the cutting assembly and the transmission belt 4 contact and squeeze each other, so that the film substrate is cut into the corresponding target shape.

[0025] In order to avoid damaging the transmission belt 4, existing treatment methods such as setting wear-resistant materials can be adopted at the position on the surface of the transmission belt 4 corresponding to the cutting assembly.

[0026] Embodiment 2:

[0027] Please refer to Figures 1-4 , based on Embodiment 1, the present utility model provides a technical solution: the cutting assembly includes a rotating roller 6. Cutting frames 7 are uniformly arranged on the outer circumferential surface of the rotating roller 6. The cutting frames 7 are in contact with the upper surface of the transmission belt 4. The edges of the cutting frames 7 are set in a sharp bayonet shape.

[0028] Analysis of the above content: The shape and size of the cutting frames 7 match the shape and size of the target film. In this way, after the cutting frames 7 contact and squeeze the film substrate, the film profile is cut into the corresponding shape.

[0029] Embodiment 3:

[0030] Please refer to Figures 1-4, the present utility model provides a technical solution based on Embodiment 2: An elastic sheet 13 is arranged inside the cutting frame 7, and one end of the elastic sheet 13 facing the outside of the cutting frame 7 is connected with a push plate 12 (under the supporting action of the elastic sheet 13, usually the push plate 12 protrudes from the cutting frame 7).

[0031] Analysis of the above content: When the cutting frame 7 cuts, the elastic sheet 13 elastically presses on the film through the push plate 12. After cutting, the push plate 12 is pushed by the elastic force of the elastic plate 13 to push the film away from the cutting frame 7, avoiding adhesion between the cutting frame 7 and the film.

[0032] Embodiment 4:

[0033] Please refer to Figures 1-4 , the present utility model provides a technical solution based on Embodiment 1: Support rods 8 are connected to the left sides of both of the U-shaped frames 1. A winding wheel 9 is installed between the left sides of the two support rods 8 through a rotating shaft. A winding motor 10 is installed on the outer wall of the support rod 8. Sprockets are installed at the end parts of the output shaft of the winding motor 10 and the rotating shaft of the winding wheel 9. The two sprockets are connected by a chain. A film receiving box 11 is arranged on the upper right side between the two support rods 8. The film receiving box 11 is hollow and has an open upper part.

[0034] Analysis of the above content: During use, the left end of the film substrate is wound by the winding wheel 9. Based on the driving of the winding motor 10 on the winding wheel 9, the winding wheel 9 winds the film substrate, and the target-shaped film cut from the film substrate falls from the film substrate into the film receiving box 11 for centralized collection.

[0035] The above shows and describes the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present utility model.
