Spray gun for new powder coating of electric heating tube electroplating

The newly developed spray gun for powder coating is characterized in that it includes: a body, which has a chamber inside, one end having an inlet hole for introducing high-pressure air, and a pivot hole connecting the chamber; A power component, which has an outer tube arranged in the chamber of the body, a tubular main shaft rotatably arranged in the outer tube, and a driving disc connected to one end of the main shaft, wherein the main shaft has a channel, the driving disc has a through hole connected to the channel of the main shaft and the pivot hole of the body group, and the peripheral ring of the driving disc is provided with most blades opposite to the inlet hole of the body group, These blades are driven by high-pressure air and drive the spindle to rotate; A feeding pipe, whose body is penetrated into a channel of the main shaft through the pivot hole of the main body, forming a feeding port for injecting paint outside the main body and a discharging port for outputting paint inside the main body; The feeding pipe body is convex and equipped with a retaining ring, with its end face tightly adhering to the side of the body. The retaining ring body is also equipped with a connecting hole, which is communicated with the pivot hole of the body. High pressure air flows between the inner surface of the main shaft and the outer surface of the pipe body, and is then accelerated and discharged by the other end of the body; And a nozzle is connected to the other end of the main shaft of the power component, and the coating is atomized and sprayed out in a radial manner.
