Description

Technical Field

[0001] The utility model relates to the technical field of film edge trimming, in particular to a film edge trimming structure. Background Art

[0002] After the film is manufactured, when it is rolled up, the edge of the film needs to be cut to make the edge of the film neat and prevent burrs. After searching, the Chinese patent authorization number CN220115872U discloses a film trimming structure with an independent trimming mechanism. After the film is cut by the cutter, the finished film is pulled by the traction roller to the traction pressure shaft for compaction, and the edge film is pulled by the trimming rubber roller and the guide roller to the trimming pressure roller for compaction and recycling. The finished film and the edge film enter different transmission roller groups respectively, which will not affect the finished film. Moreover, the pressure of the traction pressure roller and the trimming pressure roller can be adjusted for films of different specifications respectively, without adding power components separately, which is simple and light. However, when the device trims and rolls the film, the positions of the cutting devices on both sides are fixed, and it is impossible to cut films of different sizes, so the distance of the trimming cannot be controlled.

[0005] Preferably, a cutting groove is provided inside the side wall of the top surface of the movable seat, and the bottom of the cutting knife is located inside the cutting groove, so as to facilitate cutting of the film.

[0006] Preferably, a pressure roller is rotatably connected to the bottom surface of the support block, so as to facilitate the positioning of the incoming film.

[0007] Preferably, a waste hole is provided inside the base, and the waste hole is provided on the left side of the movable groove, so as to facilitate separation of the waste after cutting.

[0008] Preferably, both ends of the winding roller are fixedly connected to limit rings, and the distance between the limit rings matches the width of the cut film, thereby preventing the film below from shifting when moving.

[0009] Preferably, the end of the connecting rod exceeds the side wall of the base, thereby preventing obstruction to the cutting of the longer edge of the film.

[0010] The utility model provides a film edge trimming structure, which has the following beneficial effects:

[0011] 1. When the film edge trimming structure is used, the close distance between the cutting knives on both sides can be conveniently changed through the cooperation between the screw rod and the movable seat, so that the distance can be conveniently changed according to the width of the film;

[0012] 2. This film edge trimming structure, when in use, connects the support block and the movable seat through a U-shaped connecting rod, which can control the distance of the cut film and allow the corresponding film to enter the U-shaped connecting rod, making it easier to block the edge waste of subsequent cutting and allow these wastes to enter the waste hole.
