The design incorporates a bidirectional screw and adjustment assembly. By rotating the bidirectional screw, the adjustment assembly is driven to allow the film side clamping mechanism to slide along the groove, thereby adjusting the clamping mechanism spacing. The tension of the plastic film is adjusted by using a cylinder and rollers, while rubber strips are used to increase friction and prevent wrinkles.

Benefits of technology

It achieves effective anti-wrinkle effect on plastic films of different widths and allows for secondary adjustment of tension, thus improving the versatility of the device.

At the same time, the tension of the plastic film can be adjusted. Since the outer wall of the take-up roller 21 has a ring array of multiple rubber strips, when the take-up roller 21 takes up the plastic film, the rubber strips come into contact with the plastic film, which can increase its friction and make it easier to take up the film.
