AI Technical Summary

Technical Problem

Existing sealing and cutting machines rely on mechanical pressure to cut films, which can easily lead to skewed cuts or burrs due to blade wear and uneven pressure. They also have a high degree of mechanical complexity.

Method used

The sealing and cutting mechanism combines a heating wire and a heating plate. By melting the film at high temperature, the resistance of the heating wire is greater than the internal heating resistance of the heating plate, and the temperature of the heating wire is higher than that of the heating plate, thus achieving high-temperature bonding and cutting of the film material.

Benefits of technology

The cut is smooth and free of debris, the mechanical structure is simple, reducing the risk of wear and improving sealing efficiency and sealing quality.
