A rotary atomizing electrostatic coating apparatus having a rotating spray head, and a paint nozzle for feeding paint on the front surface of the spray head, in which the spray head is comprising a spray head main body made of an electrically insulating material, and a plurality of discharge electrodes having nearly band-form pattern extending outward approximately along the rear side shape of the spray head main body from the central side of the spray head main body with a mutual phase difference or extending symmetrically about the axis of rotation of the spray head main body. The plurality of discharge electrodes rotate together with the spray head main body, and the discharge current in the front side direction of the axis of rotation of the spray head is made uniform and increased, thereby enhancing the painting efficiency.

Rotary atomizing electrostatic coating apparatus

An electrostatic painting system for painting an object or article under corona discharge. The system comprises a spray gun which is formed at its tip end with annular air ejection opening through which air is ejected under pressure to atomize liquid paint ejected from a paint ejection opening formed at the tip end of the spray gun. An annular wire netting-like negative electrode is fixedly disposed at the tip end of the spray gun and located coaxially around the air ejection opening. The electrode functions to form an electrostatic field and a corona discharge field between the electrode and the object to be painted and to provide electric charge to the atomized paint, upon a high negative voltage being applied to the electrode.
