AI Technical Summary
Existing methods for punching holes in plastic bags are inefficient, as the material strip cannot move, resulting in low overall punching efficiency and the problem of punching waste sticking to the holes.
The perforated disc and conveying roller driven by a servo motor, combined with an induction heating rod and a conductive sleeve, are used to create holes in the material strip through thermoforming. The temperature is controlled by the induction heating rod retracting and expanding inside the sleeve, and the exhaust gas is sucked away by an induced draft fan, enabling continuous conveying without stopping.
It improves drilling efficiency, provides clear boundaries, avoids the adhesion of punching waste, ensures good processing continuity, and has greater practicality.
