In the synchronous circular motion of the two powder spraying structures 3, the air supply device 404 is started by the control system, the air flow is transported to the air guide cylinder 702 through the air guide hose 407 and the air supply pipeline 604, and then to the vertical air guide channel 708 inside on both sides through the first air guide pipe 709.

Thus, the powder spraying work on the workpiece is realized by the two hollow powder spraying pipes 301 rotating circularly. By controlling the synchronous rotation of the first linkage rod 703 and the storage cylinder 901 by the air flow, the powder in the storage cylinder 901 falls into the perforated powder guide cylinder 906 intermittently, and the falling powder is blown out by the air flow flowing through the perforated powder guide cylinder 906 to complete the spraying. Compared with the spraying mode in which the air flow directly flows through the storage cylinder 901, the powder conveying and spraying mode can effectively improve the powder output efficiency. By intermittent powder output and air flow dynamic blowing mode, the blockage of the air holes in the perforated powder guide cylinder 906 by a large amount of powder blowing out at the same time can be effectively avoided.
