AI Technical Summary
Existing blown film feeding and anti-wrinkle devices are prone to film displacement due to gravity during the feeding process, resulting in increased wrinkles. Furthermore, they lack flow guiding function, affecting the appearance and physical properties of the film.
A device comprising a guide roller and a carrier roller is designed. The guide roller is used for limiting and guiding the flow, while the carrier roller is driven by a motor and has a built-in cooling medium for cooling. Combined with a suction pump and a scraper cleaning mechanism, it ensures uniform film adhesion and rapid cooling.
This technology achieves flatness and rapid cooling of the film during transport, avoids wrinkles and contamination, and improves the appearance and physical properties of the film.
