AI Technical Summary

Technical Problem

Existing rewinding machines are prone to wrinkles and loose winding during the material winding process, resulting in uneven slitting surfaces.

Method used

The structure employs a support frame and a lower pressure roller, which, together with a transition plate and an air inlet, forms an air cushion to support the material. The support frame drives the lower pressure roller to work in conjunction with the take-up roller, and the transition plate forms an air cushion through the air inlet to support the material, counteracting the material's own weight and preventing wrinkles.

Benefits of technology

It effectively prevents wrinkles from forming in the material during the winding process, ensuring that the material is tightly wound and facilitating subsequent slitting.

Abstract

This utility model discloses an anti-wrinkle rewinding machine, relating to the field of rewinding machine technology. It includes a first side plate and a second side plate, which are horizontally arranged. A first drive roller is connected between the first and second side plates. A second drive roller is connected between the first and second side plates on one side of the first drive roller. A transition plate is connected between the first and second side plates on one side of the second drive roller. Side frames are provided at both edges of the top of the transition plate. Several air outlets are provided at the opposite ends of the two side frames. Supports are rotatably connected to the opposite ends of the first and second side plates at the front end of the transition plate. This utility model, through a series of structures, makes the material roll more tightly, avoiding wrinkles and facilitating subsequent slitting. When the tension of the thin material drops sharply and it sags due to its own weight, the air cushion supports the material, preventing wrinkles from forming.
