Description

Technical Field

[0001] This utility model relates to the field of plastic sheet processing technology, specifically to a plastic sheet extrusion molding equipment. Background Technology

[0002] Plastic sheet extrusion molding is a process in which plastic raw materials are heated and melted in an extruder and then extruded through a die of a specific shape to form a sheet. During the extrusion process, the plastic raw materials are heated and pressurized in the extruder, gradually melting and becoming fluid. Then, they are extruded into a shape by molding equipment to form a continuous plastic sheet.

[0003] Existing technologies, such as CN221476088U, describe a sheet extrusion molding apparatus. By setting up a heat dissipation component, the heat of the plastic sheet can be conducted to the heat dissipation plate through the heating plate and the conduction column, thereby cooling the plastic sheet faster, shortening the cooling time of the plastic sheet, and improving the extrusion molding efficiency of the plastic sheet.

[0004] However, this device still has some shortcomings in its use: During the flattening process, the molten plastic may experience quality problems such as uneven thickness and uneven surface of the plastic sheet due to factors such as uneven pressure, inconsistent speed, or temperature fluctuations between the rolling roller and the conveyor belt, which will affect the overall quality and performance of the plastic sheet.

[0005] In actual production, the position of the rolling rollers of this device is fixed, which means that when it is necessary to produce plastic sheets of different thicknesses, the spacing between the rolling rollers cannot be flexibly adjusted to meet diverse production needs. Utility Model Content
