AI Technical Summary

Technical Problem

Existing rotary die-cutting machines have blades that cannot adjust the cutting depth, resulting in poor adaptability. Furthermore, the blades are prone to accumulating film debris during use, affecting the cutting effect.

Method used

A strip slitting structure suitable for a rotary die-cutting machine was designed, comprising an adjustment mechanism and a oscillating mechanism. The adjustment mechanism adjusts the cutter position via a motor-driven gear transmission to accommodate strips of different thicknesses; the oscillating mechanism uses an electric push rod to drive brushes to clean debris from the cutter.

Benefits of technology

It enables flexible adjustment of the cutter position, improves cutting accuracy and equipment stability, avoids the impact of debris on cutting results, and enhances the versatility and durability of the equipment.
