Problems solved by technology

However, due to the increasingly important application fields and the poor application environment, the structural strength requirements for plastic pipes in modern applications are getting higher and stricter, and conventional primary winding pipes still exist in some high-strength application fields. Insufficient bending and compressive capacity
Therefore, under the premise that the thickness of the pipe and the type and amount of materials used are not changed much, changing the structure by changing the process to improve the bending and compressive properties of the wound pipe is the goal that plastic pipe researchers are constantly pursuing. Now The production process of winding pipes in the existing technology is complex and the degree of automation is low, resulting in low production efficiency of the pipe body and low pass rate, resulting in high prices

Abstract

The invention discloses a compression-resistant winding pipe and a production device and process thereof. The winding pipe comprises a pipe body of a first solid wall layer and a pipe body of a second solid wall layer, a pipe body of the first solid wall layer and a second solid wall layer. There are spiral hollow rib tubes distributed in an array between the tubes of the wall layer; the production device includes a support piece, and a drive connection piece and a drive piece are rotated on the support piece, and the drive piece drives the drive connection piece to rotate on the support piece, and the support piece rotates. A winding roller is arranged on the rotating part, and the winding roller is provided with an array of rib tube support disks. pieces. The compression-resistant winding tube of the present invention is released by the heat of the upper layer, the shape of the reinforced rib tube is not easily deformed by heat accumulation, and the cross section has a higher moment of inertia and ring stiffness; the production equipment of the compression-resistant winding tube of the present invention is more automated than High, improve the production efficiency of the pipe body, and improve the qualification rate of the product.

Description

technical field [0001] The invention relates to the field of pressure-resistant winding pipes, in particular to a pressure-resistant winding pipe and its production device and process. Background technique [0002] As plastic pipes are used more and more widely, they are receiving more and more attention in the fields of urban sewage, cable laying, water and gas transportation, and industrial production. With the same weight per meter and the same material, the solid-walled plastic pipe is much less capable of withstanding external pressure than the wound structural wall pipe (hereinafter referred to as the wound pipe). Therefore, the reinforced plastic pipe such as winding pipe came into being. [0003] The winding pipe is a kind of pipe that is made of high-density polyethylene (HDPE) or high-modulus polypropylene (HMPP), and then the ribbed pipe is spirally wound on the outside of the pipe. [0004] The existing domestic winding process is a one-time winding process int...
