AI Technical Summary
In the production process of multilayer co-extruded PE film, the temperature of the raw material extruded from the extruder drops when it enters the blown film machine, resulting in poor blown film quality. Furthermore, existing equipment is difficult to effectively regulate the discharge of hot air from film bubbles of different specifications, making it less adaptable.
The multi-layer co-extrusion PE film preparation device includes a blown film mechanism, an extrusion mechanism, a connecting mechanism, a return air mechanism, and a circulation mechanism. The return air mechanism adjusts the height of hot air discharge, the connecting mechanism insulates and transports raw materials, and the circulation mechanism utilizes waste heat for insulation to ensure stable film bubble temperature.
This technology enables timely removal of hot air from film bubbles of different specifications, improving the quality and applicability of blown film production, saving energy and reducing consumption, and ensuring the stability and quality of film production.
