AI Technical Summary

Technical Problem

Most existing biodegradable express bag film heat sealing devices use a single pressure plate, which causes the unpressed part of the sealing position to lift up, affecting the sealing effect and potentially damaging the bag film.

Method used

The positioning mechanism is driven by a dual-cylinder system. The position of the pressing plate is adjusted by the third cylinder, and the second cylinder realizes automatic feeding of the bag film. The protrusion and guide rod are used to guide the bag film to ensure stable positioning before heat sealing.

Benefits of technology

It achieves stable compression and automatic feeding of biodegradable express bag film, avoiding damage to the bag film caused by unstable sealing, and improving the reliability and practicality of heat sealing.
