[0022] In this embodiment: First, the plastic pipe to be sprayed is sleeved outside the inner clamping mechanism from the axis of the painting mechanism. Then, by driving the rotating mechanism, the rotating mechanism drives the inner clamping mechanism to clamp the plastic pipe internally. After clamping, the power mechanism is started, and the power mechanism drives the painting mechanism to rotate self. At the same time, the pump body connected to the painting mechanism is started, and the pump body sprays out the mixture of high-pressure gas and paint. At the same time, with the drive of the walking mechanism, the axially moving plastic pipe and the self-rotating painting mechanism spray paint on the outer surface of the pipe, so that the paint is evenly covered on the outer surface of the pipe.

[0023] Please pay special attention to Figure 1 And Figure 3The rotating mechanism includes a worm 4 connected to one end of the No. 1 fixed seat 1 through a fixed space, the worm 4 is rotatably connected to the inner side of the fixed bracket, a forward and reverse motor 3 is installed on the outer side of the fixed bracket, the output shaft of the forward and reverse motor 3 passes through the fixed bracket and is fixedly connected to one end of the worm 4, and a worm wheel 5 meshing with the worm 4 is rotatably installed at one end of the No. 1 fixed seat 1.

[0024] In this embodiment: by starting the forward and reverse motor 3, the forward and reverse motor 3 drives the worm 4 to rotate, and the spiral portion on the outer periphery of the worm 4 drives the tooth portion of the worm wheel 5 to rotate, thereby driving the worm wheel 5 to rotate, and by controlling the forward and reverse rotation of the forward and reverse motor 3, the forward rotation or flipping of the worm wheel 5 is achieved.
