AI Technical Summary

Technical Problem

Traditional film sealing machines have low film conveying efficiency, are prone to errors, cannot automatically store items, have inaccurate positioning, poor adhesion between the film and the item, require manual removal, and have weak heat sealing and poor appearance.

Method used

The system employs a downward pressure heat-sealing assembly and an upward heat-sealing assembly that operate synchronously in both directions. Combined with a film feeding mechanism and a winding mechanism, it achieves precise film guidance, pre-sealing, and automatic recycling, ensuring that the film adheres tightly to the surface of the color box and that the heat-sealing line is firm and flat.

Benefits of technology

It improves heat sealing efficiency and yield, ensures tight adhesion between the film and the color box surface, and creates a firm and flat heat seal line, significantly improving the quality and appearance of the sealing film, reducing manual intervention, and enhancing the reliability and efficiency of the automated process.

Abstract

This utility model discloses a semi-automatic color box sealing device, including an infeed conveyor, an outfeed conveyor, a film feeding mechanism, an automatic heat sealing mechanism, and a winding mechanism. A pressure plate is fixedly installed on the upper side of the outfeed conveyor corresponding to the winding mechanism by screws. The automatic heat sealing mechanism includes a downward heat sealing component located above the outfeed conveyor and an upward heat sealing component located below the outfeed conveyor. Through an innovative top-bottom synchronous bidirectional heat sealing and cutting mechanism, it achieves efficient and precise completion of double-sided heat sealing and cutting in one action, greatly improving production efficiency. The bidirectional balanced pressure combined with a buffer design significantly improves the strength, flatness, and aesthetics of the sealing film, ensuring high-quality finished products and adapting to different workpieces. The optimized film path design and pre-sealing function ensure the accuracy of film feeding and the reliability of heat sealing. In addition, the automated waste film edge recycling system keeps the site clean and reduces manual operation.
