Description

Technical Field

[0001] This utility model relates to a sheet extrusion production line, belonging to the field of plastic extrusion technology. Background Technology

[0002] A sheet extrusion production line is a production system used to produce plastic sheets, which are planar plastic products widely used in packaging, building materials, electronics, and automotive industries. Traditional sheet extrusion production lines consist of a linear arrangement of equipment such as an extruder, die, cooler, traction machine, and winding machine. A search revealed a Chinese patent (CN217944408U) disclosing a PLA sheet extrusion production line. In this patent, the PLA sheet extrusion production line uses an extruder to heat, plasticize, and extrude PLA raw materials. A molding assembly filters, meteres, and shapes the molten PLA. Then, a cooling and edge-cutting assembly cools and cuts the edges of the sheet. Finally, a finished product collection assembly draws and winds the finished PLA sheet into a roll. This patent assembles each process piece sequentially within the factory area, resulting in a lengthy overall production structure, a large footprint, and significant requirements for factory length, thus increasing costs.
