AI Technical Summary

Technical Problem

Traditional plastic film leveling devices have a simple structure, making it difficult to effectively eliminate complex wrinkles and unevenness on the film surface. Furthermore, their single power system results in low production efficiency.

Method used

It employs a combination of surface pressure rollers and driven rollers, along with a dual-drive system. The surface pressure rollers and driven rollers work together to apply uniform pressure, while dual drive motors ensure stable power. It also integrates transverse and longitudinal cutting functions to accommodate films of different specifications and roll diameters.

Benefits of technology

It improves the flatness and quality of the film, ensures stable power, expands the applicability of the device, increases production efficiency, and reduces manual operation.
