Technical Field
[0001] This utility model belongs to the technical field of water-cooled blown film equipment, and in particular relates to an auxiliary winding machine for multi-layer co-extrusion water-cooled blown film equipment. Background Technology
[0002] In the film production process, multi-layer co-extrusion down-blown water-cooled blown film equipment fuses various plastic raw materials with different properties through multi-layer co-extrusion, and then cools and shapes them through down-blown water cooling to produce high-quality films. The auxiliary winding machine, as a key component of this equipment, undertakes the important task of orderly and efficient winding of the formed film, directly affecting the continuity of film production and product quality.
[0003] However, the existing auxiliary winding machines used in multi-layer co-extrusion down-blown water-cooled blown film machines have many drawbacks. During the formation of multi-layer co-extrusion down-blown films, unevenness and non-uniformity of the film surface are prone to occur, which seriously affects the quality of the film. In addition, traditional winding machines mostly use single-station winding and lack an effective switching mechanism, which requires the machine to be stopped to replace the core during the winding process, greatly reducing production efficiency.
[0004] To address these issues, we provide an auxiliary winding machine for a multi-layer co-extrusion down-blown water-cooled blown film machine. Utility Model Content
