AI Technical Summary

Technical Problem

In existing composite film production, the passive unwinding of the raw material rollers causes the composite film to stretch and deform, and the adjustment is inconvenient, affecting the flatness of the finished product and the interlayer adhesion strength, as well as the clamping stability.

Method used

The feeding structure combines a rotary driver and a linear driver. The raw material roller is actively unwound by the rotary driver, and the power transmission is controlled by an electromagnetic clutch. The linear driver adjusts the mounting frame spacing to accommodate raw material rollers of different lengths.

Benefits of technology

This technology enables stable transport of composite membranes, avoids stretching deformation, improves finished product quality and operational flexibility, and enhances the safety and adaptability of the equipment.
