AI Technical Summary

Technical Problem

In the process of cutting aluminum foil and paper feed, the existing cutting machine suffers from insufficient winding tension of the unwinding shaft, resulting in reduced cutting accuracy and burrs. Furthermore, adding a magnetic powder tension controller separately for the paper feed is costly.

Method used

By using a tension adjuster that abuts against the first shaft, the unwinding tension is adjusted by increasing the sliding friction. This is combined with a magnetic powder tension controller for aluminum foil rolls, which reduces costs while improving cutting accuracy.

Benefits of technology

It effectively improves cutting accuracy, reduces burr generation, and lowers production costs.
