PVC plastic pipe manufacturing and forming method

Abstract

The invention relates to a PVC plastic pipe manufacturing and forming method. A bottom plate, a hot melting extruder, a cooling device, a grinding device, a cleaning device and a driving device are arranged to cooperatively manufacture a PVC plastic pipe. According to the PVC plastic pipe manufacturing and forming method, the problems that when existing PVC plastic pipe manufacturing equipment isused for manufacturing the PVC plastic pipe, the PVC plastic pipe subjected to hot melting extrusion is directly cooled, the existing PVC plastic pipe manufacturing equipment can only cool the PVC plastic pipe with the single diameter, when the PVC plastic pipes with different diameters are cooled, a mold needs to be replaced, the mold replacement process is tedious, consequently, the PVC plasticpipe manufacturing efficiency is low, the existing PVC plastic pipe manufacturing equipment directly cools and collects the PVC plastic pipe, the deformed PVC plastic pipe in the cooling process is not corrected, consequently, the diameters of the same PVC plastic pipe are different, and use of the PVC plastic pipe is affected can be solved.

Description

technical field [0001] The invention relates to the technical field of plastic pipe production, in particular to a PVC plastic pipe production and molding method. Background technique [0002] The main component of PVC plastic pipe is polyvinyl chloride, which is a material made of polyvinyl chloride resin, stabilizer, lubricant, etc., and then extruded by hot pressing to enhance its heat resistance, toughness, and ductility. PVC plastic pipes are mainly used for water supply system piping, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation in housing construction. In the process of making PVC plastic pipes, it is necessary to cool the PVC plastic pipes after hot-melt extrusion, so that the extruded PVC plastic pipes are cooled and shaped. [0003] Existing PVC plastic pipe production equipment often has the following problems when making and molding PVC plastic pipes: [0004] (1) Exis...

AI Technical Summary

Problems solved by technology

[0004] (1) Existing PVC plastic pipe production equipment directly cools the PVC plastic pipe after hot-melt extrusion when making PVC plastic pipes, and the existing PVC plastic pipe production equipment can only process single-diameter PVC plastic pipes are cooled. When cooling PVC plastic pipes with different diameters, the mold needs to be replaced. The mold replacement process is cumbersome, resulting in low production efficiency of PVC plastic pipes;

[0005] (2) Existing PVC plastic pipe production equipment usually directly cools and collects PVC plastic pipes when making PVC plastic pipes, and does not correct the deformed PVC plastic pipes during the cooling process, resulting in the diameter of the same PVC plastic pipe Different, affecting the use of PVC plastic pipes
