Abstract
A powder coating device includes a reaction device, a driving device, a gas supply device, and a gas delivery device. The gas delivery device includes a rotating shaft and a sleeve. The rotating shaft is connected to an inner cylinder and the driving device, and a first gas path communicated with a reaction chamber is defined along an axis of the rotating shaft, and a plurality of gas holes for communicating the first gas path with outside of the rotating shaft are defined in the rotating shaft. The sleeve is sleeved on the rotating shaft, and a second gas path for the rotating shaft to pass through is defined in the sleeve, the second gas path is communicated with the gas supply device, and the plurality of the gas holes is located inside the second gas path.
