Description

Forming device for HDPE plastic manufacturing Technical Field The utility model belongs to the technical field of HDPE plastic sheet production, and particularly relates to a forming device for manufacturing HDPE plastic. Background The traditional manufacturing process of High Density Polyethylene (HDPE) plastic sheets generally employs "extrusion+roll" two-stage processing, namely, extruding a thick sheet through a single screw extruder die head, and then calendaring to a target thickness through a roll former. However, in the roll forming stage, the HDPE melt is subjected to transverse stress, the edges on two sides of the sheet are easy to generate wave deformation or ultra-poor thickness due to uneven flow, the edge defect not only affects the dimensional accuracy of the product, but also needs to be provided with an independent edge cutting device for cutting off about 2-5% of the edge materials, and the traditional edge cutting device is independent of roll forming equipment, so that the length of a process chain is increased, the occupied area of the equipment is increased, and the flatness of the product is affected due to tension fluctuation generated by secondary positioning. Therefore, the utility model provides the forming device for manufacturing the HDPE plastic, the synchronous edge cutting technology shortens the process flow, improves the comprehensive energy efficiency of equipment, reduces the occupied area of the equipment, avoids the influence of tension fluctuation generated by secondary positioning on the flatness of the product, and improves the production quality of the HDPE plastic sheet.
