Frame-shaped spiral winding plastic pipe as well as production equipment and production process thereof

Abstract

The invention belongs to the technical field of municipal drainage and sewage discharging pipelines, and relates to a frame-shaped spiral winding plastic pipe as well as production equipment and a production process thereof. More than one hollow rectangular pipe or hollow arched pipe is transversely formed on an external surface of a plastic tape of the frame-shaped spiral winding plastic pipe at intervals, wherein the top surface of the arched pipe is in smooth transition, a connecting edge is arranged at one side of the frame-shaped spiral winding plastic pipe, and an upper surface of an edge at the other side extends outwards to form a fastening edge, so as to form strip profiles, and the frame-shaped spiral winding plastic pipe is formed by adhering and connecting the strip profiles through a hot melt adhesive after spiral winding. The production equipment comprises an extruding machine, a profile mould, a shaping mould, a cooling and shaping platform, a traction machine, a winding mechanism, a carrying platform and a pipe cutting saw. The production process comprises the following steps: shaping the strip profiles, winding the strip profiles in a spiral manner, and adhering and connecting the strip profiles through the hot melt adhesive to form a pipe. The frame-shaped spiral winding plastic pipe as well as the production equipment and the production process thereof disclosed by the invention have the following advantages: material cost and equipment manufacturing cost are lowered while performance of the pipe is improved, the product is safe and reliable, and the frame-shaped spiral winding plastic pipe can meet the requirement on long-term use, and is applicable to producing large-diameter municipal drainage and sewage discharging pipelines.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage and sewage pipes, in particular to a frame-shaped spirally wound plastic pipe and its production equipment and production process. Background technique [0002] With the continuous development of urbanization, the market for municipal drainage and sewage pipes is very large, especially in China, where the economy is booming. Road projects, municipal projects, rain and sewage diversion projects, and large-scale industrial parks under construction in various parts of our country require a large number of reliable, durable and environmentally friendly pipelines. [0003] Since there is no pressure in the drain pipe, in order to improve the performance of resisting external pressure and impact, different forms of reinforcement structures are set up on the outer periphery of the plastic pipe wall. According to the structural form of the pipe and its preparation method, it is divided into se...

AI Technical Summary

Problems solved by technology

Since the pipe is a continuously extruded pipe, it is difficult to produce a pipe with a diameter of more than 1000mm due to the constraints of the pipe equipment, and the equipment manufacturing cost is very expensive

In addition, the hollow winding pipe and Clarke pipe produced by winding, although the equipment manufacturing cost is not high, the weight of the produced pipe is large per meter, which makes the production cost very high

The spiral pipe produced by steel belt reinforced spiral pipe, although the equipment manufacturing cost is not high, because the steel belt is added, the production cost is greatly reduced, but the anti-corrosion problem of the product cannot be solved, so the product cannot be used for a long time
