ABSTRACT:
A coating machine is capable of reducing VOC and CO2by atomizing a paint to increase depositing efficiency without lowering production efficiency and the rotary atomizing head of the coating machine. The coating machine includes the rotary atomizing head in which a paint chamber receiving the supply of paint is formed on the rear side thereof. A plurality of rims formed in a roughly truncated conical shape for extending the paint flowing out of the paint chamber by a centrifugal force and atomizing the paint at the tip thereof are fitted in the rotary atomizing head overlappingly at specific clearances. The clearances are opened to the peripheral surface part of the paint chamber. Accordingly, VOC and CO2can be reduced by reducing the total jetted amount of paint to enable the atomization of the paint at low rotating speeds so as the increase the deposit efficiency.
