Description

TECHNICAL FIELD

[0002] Under the existing background, a certain amount of coated pipe waste pipe is generated during the debugging and production of the polyethylene extrusion coated pipe forming device. The coated pipe waste pipe needs to be stripped of the coating layer on its surface to separate it into a coating material and a base pipe, so as to be reused. The traditional method is to first collect all pipe materials that need to be stripped of the coating layer, and then arrange the outer coating layer stripping operation. The stripping operation uses a craft knife to first cut the outer coating layer, and then uses a tool to separate the adhered polypropylene outer coating layer from the bottom pipe from the cut part. The traditional operation using the craft knife is easy to cause injury to the workers. Moreover, the coating layer material is polypropylene. The polypropylene plastic shrinks and adheres tightly during the cooling process. After complete cooling, the hardness is relatively high, and the polyethylene pipe material of the bottom layer is adhered tightly, so it is not easy to cut and complete the stripping operation.
