Pipeline winding coating machine and winding coating method thereof

Abstract

The invention discloses a pipeline winding coating machine and a winding coating method thereof, and belongs to the technical field of winding machines. The pipeline winding coating machine comprisesa supporting device and an extruder arranged on one side of the supporting device, and is characterized in that the supporting device comprises a plurality of sets of supporting rollers (5) arranged side by side, detection devices and translation devices, wherein each group of supporting rollers (5) comprises two supporting rollers (5) symmetrically arranged on two sides of a pipeline (7); each group of supporting rollers (5) is connected with a power device for driving the supporting rollers (5) to rotate; each group of supporting rollers (5) is rotatably arranged on the corresponding translation device; the translation devices push the supporting rollers (5) to move along the direction close to or far away from the pipeline (7); the rear side of each group of supporting rollers (5) alongthe feeding direction of the pipeline (7) is provided with one detection device for detecting the outer diameter of the pipeline (7); and each detection device is connected with the corresponding translation device. The pipeline winding coating machine can adapt to winding coating of a pipeline with a boss on the outer wall. According to the winding coating method, polyethylene is wound on the pipeline with the two ends being flared.

Description

technical field [0001] A pipe winding coating machine and a winding coating method thereof belong to the technical field of winding machines. Background technique [0002] At present, domestic water supply and drainage, heating, etc. are all transported by pipelines. The pipelines are usually made of metal. In order to improve the performance of the pipeline, it is usually necessary to coat the outer wall of the pipeline. The pipeline coating is currently carried out by a pipeline coating winding machine. The pipeline is supported by multiple sets of rollers. In this way, the winding of the pipe coating is completed. However, due to the limitation of the supporting rollers, the existing winding machines can only wind pipes with uniform diameters, and the pipes used for transportation will inevitably face the problem of butt joints, which usually requires butt joints at the ends of the pipes, thus affecting The support of the idler roller is lost, which leads to the inabilit...

Problems solved by technology

However, due to the limitation of the supporting rollers, the existing winding machines can only wind pipes with uniform diameters, and the pipes used for transportation will inevitably face the problem of butt joints, which usually requires butt joints at the ends of the pipes, thus affecting The support of the idler roller is not supported, which leads to the inability of the winding machine to realize the winding work smoothly, which affects the use of the winding machine
