液体塗料静電塗装用の回転霧化装置。It consists of a rotating body having an annular discharge edge, and is coaxially mounted and fixed to the front end of the rotating shaft of the rotary drive device and rotated, and the liquid paint supplied to the central part of the rotating body is transferred to the rotating body. Based on the rotation of the rotating body, a thin film-like flow whose thickness gradually decreases along one surface of the rotating body is guided toward the entire circumference of the annular discharge edge, and is formed between the rotating body and the object to be coated. A rotary atomizer for electrostatic coating of liquid paint which is electrostatically atomized and discharged from an annular discharge edge by the action of a DC high voltage applied to the annular discharge edge of the rotating body. The edges are not sharp rectangular edges, but edges with narrow, uniform width end faces that are approximately perpendicular to or close to the axis of the rotating shaft, so that the liquid paint on the rotating body is The guide surface has a generally V-shaped or elongated trapezoidal planar shape and a generally triangular or trapezoidal cross-sectional shape or a generally arcuate cross-sectional shape on the peripheral edge portion of the surface to be guided, and extends generally in the direction of flow of the liquid paint flow. A large number of approximately equal shallow grooves whose widths and depths increase as they approach the discharge edge are arranged close to each other with substantially the same spacing between the center lines of the grooves, and the outside of each groove. characterized in that each end is opened at the end face of the annular edge;
