[0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It is used for packaging and as a coating layer. Plastic packaging and plastic packaging products are taking up an increasingly large share of the market, especially composite plastic flexible packaging, which has been widely used in the food, pharmaceutical and chemical industries.

[0003] In the production process of plastic film, in order to meet product design requirements, improve appearance quality, ensure dimensional accuracy, reduce defects, and facilitate subsequent processes and applications, it is necessary to trim the edges of the plastic film.

[0045] The working principle of the adjustable plastic film trimming device provided by this utility model is as follows:

[0046] A mounting shell 11 with a bidirectional adjusting screw 25 and a slide bar 24 is installed on the top of the fixed frame 8. Then, two internal threaded frames 23 are installed on the outer surfaces of the bidirectional adjusting screw 25 and the slide bar 24. The drive assembly 21 provides rotational driving force to rotate the bidirectional adjusting screw 25, allowing the two internal threaded frames 23 to move synchronously closer and further apart. During this process, the slide bar 24 increases the stability of the internal threaded frames 23's movement. Then, two cutting blades 29 are installed below the two movable plates 14 using mounting clips 30, with the cutting blades 29 adjacent to the pressure rollers 27 below the movable plates 14. The telescopic component 9 is used to extend and retract the cutting blades 29, moving them up and down. In actual use, the plastic film roll is first placed in the position of the film feeding roller 5, and then... One end of the plastic film is connected to the take-up roller 16, and the plastic film and the edge cutting block 31 are adhered by two guide rollers 15. Then, the take-up driver 17 is started to drive the take-up roller 16 to rotate, which moves the film to a different position. During the edge cutting process, only two telescopic components 9 need to be started to drive the two movable plates 14 to move downward to the corresponding position. Then, the drive assembly 21 is started to drive the bidirectional adjusting screw 25 to rotate, so that the distance between the two internal threaded frames 23 can be adjusted as needed, so that the edge cutting tool 29 is precisely aligned with the position to be cut. Then, the telescopic component 9 is started to press the pressure roller 27 to press the plastic film. During this process, the pressure roller 27 is subjected to force and compresses the auxiliary spring 26. Without affecting the pressure roller 27's limit on the plastic film, the edge cutting tool 29 cuts the film.

[0047] Compared with related technologies, the adjustable plastic film trimming device provided by this utility model has the following advantages:

[0048] Beneficial effects:

[0049] To improve the accuracy and stability of synchronous edge cutting on both the front and back sides of the plastic film, a mounting shell 11 with a bidirectional adjusting screw 25 and a slide bar 24 is installed on the top of the fixing frame 8. Two internal threaded frames 23 are then mounted on the outer surfaces of the bidirectional adjusting screw 25 and the slide bar 24. The drive assembly 21 provides rotational driving force to rotate the bidirectional adjusting screw 25, allowing the two internal threaded frames 23 to move synchronously closer and further apart. During this process, the slide bar 24 increases the stability of the movement of the internal threaded frames 23. Then, two edge-cutting blades 29 are mounted below the two movable plates 14 via mounting clips 30, with the edge-cutting blades 29 adjacent to the pressure rollers 27 below the movable plates 14. The telescopic component 9 extends and retracts, causing the edge-cutting blades 29 to move up and down. This design uses the rotation of the bidirectional adjusting screw 25 to drive the two sets of edge-cutting blades 29 to move stably closer and further apart. With the cooperation of the distance measuring component 12, the adjustment accuracy can be precisely controlled, improving the accuracy and stability of synchronous edge cutting on both the front and back sides of the plastic film, thus enhancing the edge-cutting effect of the plastic film.
