Extrusion molding mechanism for ultrahigh molecular weight polyethylene composite pipe

Abstract

The invention belongs to the technical field of polyethylene composite pipe production, particularly relates to an extrusion molding mechanism for an ultra-high molecular weight polyethylene composite pipe, and provides the following scheme aiming at solving the problem that discharged materials are easy to bend. The extrusion molding mechanism comprises a workbench and an extruder, and a water storage chamber and a dust storage chamber are correspondingly formed in the middle and one side in the workbench; a cooling lantern ring is installed at the top of the workbench, a water supply pipe is wound in the inner wall of the cooling lantern ring, a cooling circulation mechanism is arranged in the water storage chamber, electric sliding tables are installed at the two ends of one side of the top of the workbench, installation boxes are installed in the middles of the output ends of the two electric sliding tables, and fixing rings are arranged at the bottoms of the installation boxes; and synchronous moving mechanisms are arranged in the installation boxes, a cutting knife is arranged at the top of the workbench, and a dust suction nozzle is mounted on the side face of the cutting knife. The device ensures that the polyethylene composite pipe always keeps horizontal movement, avoids bending caused by deviation, has a cooling function, and avoids deformation of the polyethylene composite pipe due to incomplete cooling.

Description

Technical field[0001]The present invention relates to the field of polyethylene composite tube processing techniques, and more particularly to an extrusion forming mechanism of an ultra-high molecular polyethylene composite tube.Background technique[0002]The polyethylene composite tube is a composite tube extruded with a variety of plastic extruded, with high-density polyethylene and low density polyethylene material composite type of tubular, and its withstand voltage and corrosion resistance are ratio. Ordinary polyethylene tubes are good, due to their good withstand resistance and corrosion resistance, it is often used in the delivery of oil and gas, not only long service life, but also ensures the safety of the line. Polyethylene composite tube needs to be used in the production process to use the extrusion molding mechanism[0003]The extruded molding mechanism of the existing ultra-high molecular polyethylene composite tube often uses crawler traction to pull the pipe from the m...

AI Technical Summary

Problems solved by technology

[0003] The existing extrusion molding mechanism of ultra-high molecular weight polyethylene composite pipe often uses crawler traction to pull the pipe out of the mold, but it cannot guarantee that the pipe is always kept horizontal during the traction process, and it is easy to cause the pipe to deviate and cause the pipe to bend; now Some extrusion molding mechanisms of ultra-high molecular polyethylene composite pipes are not equipped with cooling mechanisms, which can easily lead to deformation when the pipes are not completely cooled when they are discharged from the composite pipe extrusion die, which greatly reduces product quality.
