Composite film guiding and pulling device
By designing structures such as grooves, sliders, tension rollers, and push springs, the problem of wrinkles caused by insufficient tension during the cutting process of composite films is solved, ensuring the flatness of the composite films and the cutting effect.

AI Technical Summary
In the current composite film production process, the guiding and traction method cannot effectively tighten the composite film, resulting in wrinkles during cutting and affecting the cutting effect.
The structure employs a strip groove, slider, tension roller, and push spring. The push spring pushes the slider to move the tension roller, thus tensioning the composite film. The position of the cutting disc is adjusted by a fixed cylinder and a set screw to ensure the flatness of the film.
This achieves a smooth and taut composite membrane, avoids wrinkles, and improves cutting results.
