Abstract

The invention discloses a plastic composite pipe end sealing device of a steel skeleton. The plastic composite pipe end sealing device comprises a car body (12), wherein a thermo-extrusion gun (6) and a heat gun (5) are arranged on the car body (12); a stock mold (8) of a bar groove is arranged at the plastic outlet of the thermo-extrusion gun (6); micro-adjusting mechanisms are arranged on the thermo-extrusion gun (6) and the heat gun (5). Compared with the prior art, the plastic composite pipe end sealing device is simple in structure, has a good sealing effect, and can seal the end part of a plastic composite pipe of the steel skeleton without a corresponding annular cover plate manufactured in advance, the production cost can be greatly reduced, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a sealing device for the end of a steel skeleton plastic composite pipe. Background technique [0002] During the production process of steel skeleton plastic composite pipe, especially after sawing, the steel skeleton on the end face of the pipe will be exposed to the outside of the plastic, which is easy to cause oxidation and corrosion. [0003] Therefore, after the steel frame plastic composite pipe is formed, the end must be sealed to prevent corrosion of the steel frame on the end face of the pipe. [0004] The current processing method is to paste a pre-formed ring-shaped cover with a fixed diameter on the end of the pipe by heat sealing. The pasting process is very complicated, and it is necessary to pre-customize the corresponding The ring-shaped cover sheet of the pipe diameter further increases the production cost. Contents of the invention [0005] The purpose of the present invention is to provide a device whic...
