[0003] In the existing technology, although a certain effect of painting the inner wall of the pipe can be achieved during use, there is a defect: the existing composite pipe inner wall spraying device lacks the working effect of efficient spraying and installation simultaneously, resulting in the pipe body needing to be installed before it can be sprayed, resulting in reduced work efficiency. In view of this, we propose an inner coating device for plastic-coated composite pipes to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. The utility model can realize the rapid clamping of the tube body by utilizing the mounting groove provided on the surface of the rotating frame. After the clamping, one of the tube bodies will realize the spraying effect of the inner wall under the processing of the rotating column. After the processing, the rotating frame rotates 60 degrees to carry out the spraying of the next tube body.
