Wall tube with reinforced polyethylene-wound structure as well as manufacturing device and manufacturing method thereof

Abstract

The invention relates to a wall tube with a reinforced polyethylene-wound structure. The wall tube is composed of a tube body, and a socket and a faucet at the two ends of the tube body, wherein the tube body is composed of an inner wall layer and an outer wall layer; the inner wall layer is a continuous solid wall tube formed by spirally winding the sheet-shaped polyethylene strips, and the edges of adjacent strips are mutually overlapped and fused in succession; and the outer wall layer is a convex reinforced rib formed by spirally winding tubular polyethylene strips on the outer surface of the inner wall layer; and the tubular polyethylene strips are spirally pressed at places on which the edges of the adjacent sheet-shaped polyethylene strips are overlapped and fused in a bridged mode. The innovation of the invention lies in that both ends of the inner wall layer of the tube body are provided with a faucet, and a faucet at one end of the inner wall layer of the tube body is coaxially provided with a socket. The socket and the faucet can be produced in an online continuous mode, thus realizing easiness in processing and high production efficiency; and moreover the socket and the faucet are easy to install, has good sealing reliability after being connected. Meanwhile, the tube uses a structure without a skeleton, and has the advantages of small raw material consumption, short processing time, light product weight, low cost and the like. The invention also relates to a manufacturing device and a manufacturing method of the wall tube with the reinforced polyethylene-wound structure.

Description

technical field [0001] The invention relates to the technical field of plastic pipes and their processing, in particular to a reinforced polyethylene winding structural wall pipe with a socket socket without a skeleton, a production device and a production method. Background technique [0002] At present, in many fields such as urban sewer pipes and drainage projects, environmentally friendly plastic pipes are widely used due to their excellent performance. There is no pressure inside the drain pipe. In order to improve the performance of resisting external pressure and impact, different forms of reinforcing ribs are set on the outer periphery of the pipe wall. There are two main types of commonly used plastic pipes with reinforcing ribs: one is made by direct extrusion molding, the most representative is double-wall corrugated pipe; the other is made by spiral winding, representing double-wall corrugated pipe. Wall pipes, polyethylene winding structural wall pipes and stee...

AI Technical Summary

Problems solved by technology

[0005] Double-wall corrugated pipes, hollow winding pipes, and steel belt reinforced pipes can be produced continuously, but pipe sockets cannot be produced; high-density polyethylene winding wall pipes can produce pipes with sockets, but continuous production of pipes cannot be realized. It can be a mold to produce a pipe, and the production efficiency is low
