Plastic pipeline hot melting connecting device

Abstract

The invention belongs to the technical field of plastic pipeline machining, and particularly relates to a plastic pipeline hot melting connecting device which comprises a supporting base. Two guide sliding rods are arranged between the left end and the right end of the supporting base; the left end and the right end of each guide sliding rod are fixedly connected with the left end and the right end of the supporting base correspondingly; a first fixing clamping piece, a second fixing clamping piece, a third fixing clamping piece and a fourth fixing clamping piece are arranged on the surface of each guide sliding rod; and a plurality of connecting columns are arranged between the first fixing clamping pieces and the second fixing clamping pieces. By cutting the end part of a plastic pipeline into the inclined surface, the contact area during hot melting connection of the pipeline is increased, and heat absorption treatment on the edge of the inner wall of the pipeline is matched, so that the influence on the inner side after hot melting of the pipeline is relieved, and the problems that in the hot melting process, the plastic pipeline turns over towards the inner side of the pipeline after hot melting, the pipe diameter of a pipeline joint is reduced in the subsequent pipeline splicing process, the actual conveying flow of the pipeline is reduced, and the liquid flowing resistance is increased are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of plastic pipe processing, and in particular relates to a plastic pipe hot-melt connection device. Background technique [0002] Plastic pipe refers to the general term for pipes made of plastic materials. Plastic pipe has the characteristics of light weight, sanitation and safety, small water flow resistance, energy saving, metal saving, improvement of living environment, long service life, safety and convenience, etc., and is favored by the pipeline engineering industry. Compared with traditional metal pipes and concrete pipes, plastic pipes have more advantages in many fields, so they are recommended for use in many areas. Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, plastic pipes are energy-saving. Material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and m...

AI Technical Summary

Problems solved by technology

[0003] In order to facilitate the transportation and use of plastic pipes, the pipes will be spliced ​​for the laying of long-distance pipes. At present, plastic pipes are mostly connected by hot melting, and the surface of the plastic pipe reaches the melting point by heating. A connection method of post-connection. In the process of hot-melting plastic pipes, the plastic pipes will turn inside the pipe after hot-melting, and the diameter of the pipe joint will become smaller during the subsequent pipe splicing process, resulting in the actual flow rate of the pipe. It will be reduced, and the liquid flow resistance will increase.
