Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to a plastic pipe end surface grinding device. Background Art

[0002] Plastic pipe is a kind of chemical building material, which is mainly made of synthetic resin, and auxiliary materials such as stabilizer, lubricant and plasticizer are added to it. It is made by extrusion processing method. The material of plastic pipe has the advantages of corrosion resistance, light weight, energy saving and environmental protection. It is widely used in: agricultural irrigation, municipal water supply and drainage, gas pipelines and other fields. However, there will be a lot of burrs on the end face of plastic pipe during the production process. In order to improve the quality of the pipe and make the end face smoother, it needs to be polished. There are many kinds of plastic pipe end face polishing devices currently available on the market, but there are still some disadvantages;

[0003] For example, in actual use, a general plastic pipe end face grinding device uses sandpaper to grind the pipe. The pipe is not clamped and fixed during the grinding process, so the pipe moves, which affects the grinding accuracy of the pipe end face. At the same time, the general grinding device cannot grind the end faces of pipes of different diameters and lengths, and its practicality is poor. In addition, when grinding the pipe end face, waste chips will fly, which will affect the surrounding environment and will also fly into the eyes of the operator, causing eye injuries to the operator. Therefore, we propose a plastic pipe end face grinding device to solve the above problems. Utility Model Content
