Description

Technical Field

[0001] This utility model relates to the field of plastic calendering technology, and in particular to a high-efficiency and energy-saving plastic product calendering machine. Background Technology

[0002] Plastic calenders are core equipment used to process thermoplastic plastics into shapes such as films, sheets, and pipes through extrusion, stretching, and cooling processes. Plastic calenders apply pressure and shear to molten or semi-molten plastics through multiple rollers to achieve material extension and uniform thickness. They are mainly used to produce PVC films, plastic sheets, and pipes.

[0003] Existing plastic calenders, when in actual use, cannot cool the hot melt rubber material in time with their calendering rollers, resulting in poor cooling effect. Furthermore, the sheet-like rubber material passing through the calendering rollers lacks a guiding structure and is easily damaged when falling onto the horizontal conveyor, affecting the molding effect. To address these issues, a high-efficiency and energy-saving plastic calender is proposed. Utility Model Content
