AI Technical Summary

Technical Problem

In existing polyester film slitting equipment, when the rotating rod is fixed, the bolts exert force on the clamps in a single point or localized concentration, resulting in uneven distribution of contact pressure, affecting the uniformity of cutting force and reducing product quality.

Method used

The traditional circular blade fixing rod is replaced by an airbag fastening method. The outer wall of the slip is wrapped by an annular airbag. When the annular airbag expands, it squeezes the slip from all directions simultaneously, eliminating off-center load, automatically adjusting the pressure distribution, and ensuring uniform pressure application.

Benefits of technology

This technology ensures stable clamping of the clamp to the rotating rod during the polyester film slitting process, eliminates eccentric load caused by unilateral pressure, ensures uniform cutting force, and improves product quality.
