Description

Plastic sheet extrusion production line

Technical Field

The utility model belongs to the technical field of mechanical equipment, especially, relate to a plastic sheet extrusion line.

Background

Extrusion processing is the main manufacturing method of plastic molding, a plastic master batch mixture is extruded into hot-melt colloid by an extruder at a certain temperature, the hot-melt colloid is shaped for the first time by a forming die, and the shaped colloid is cooled and shaped by adopting a cooling medium which is usually water. Unlike extrusion processing of tubular materials, sheet materials require higher thermoforming and cooling control due to the difference in transverse and longitudinal dimensions. In particular, when processing a sheet having a large aspect ratio and a large thickness, the following disadvantages are present: 1) in the process of cooling the sheet material after extrusion, the shrinkage stress generated by cooling in the transverse direction and the longitudinal direction is different, and irregular deformation is easy to generate; 2) high production efficiency is difficult to obtain, when the extrusion rate is increased, the material cannot be sufficiently cooled, and the performance is difficult to guarantee; 3) in actual production, the extrusion rate is generally increased by increasing the cooling length, the transverse and longitudinal deformation difference is increased in the cooling process with large length, and the production operation space is required to be large, so that the method is not economical.
