Novel extruding machine equipment for plastic pipes

Abstract

The invention discloses novel extruder equipment for plastic pipes, and particularly relates to the related technical field of plastic pipe production, the novel extruder equipment comprises an extrusion molding structure, and one side of the extrusion molding structure is provided with a circulating cooling structure for cooling and molding the plastic pipes; and the circulating cooling structure comprises a cooling pond used for soaking and cooling the water pipe, a water pumping pipe is arranged in one side of the cooling pond, one end of the water pumping pipe is fixedly connected with a water pump, and a conveying pipe is fixedly installed at the water outlet end of the water pump. By using the circulating cooling structure and the heat dissipation structure, an extruded pipe is soaked in cold water and sprayed with the cold water, water making contact with the pipe enters the heat exchange pipe for heat exchange when getting hot, then raw materials for pipe injection molding are preheated, meanwhile, through heat exchange and using of the heat dissipation pipe and heat dissipation fins, the heat dissipation temperature of hot water is reduced, and the heat dissipation efficiency is improved. And the cold water is recycled for cooling, so that the dual requirements of cooling and preheating are met.

Description

technical field [0001] The invention relates to the technical field related to the production of plastic pipes, and more specifically, the invention relates to a new type of extruder equipment for plastic pipes. Background technique [0002] As an important part of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection, and low consumption. They mainly include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, and polyethylene (PE) pipes. Water supply pipes, polypropylene PPR hot water pipes, and plastic pipes are often produced by thermoplastic extrusion. [0003] China Patent Authorization Announcement No. CN111231262B, date of announcement is November 09, 2021. The invention discloses an environmentally friendly plastic extruder, which relates to the field of mechanical equipment. The temperature is low, which affects the work efficiency. This device is mainly ...

Problems solved by technology

[0005] The announcement number CN111231262B in the above-mentioned prior art proposes to recycle the heat energy of the extruder, but lacks the cooling molding structure for the extruded object, and the patent of the announcement number CN110789090B rapidly cools the extruded object through a fan, and the cooling time is not enough It is easy to affect the quality of extruded products. Too long cooling time will lead to low processing efficiency. At the same time, the cooling structure of injection molding equipment commonly used in the market has the same problem. Therefore, it is necessary to propose a new extruder equipment for plastic pipes.
