る。 Thus, in the above embodiment, the paint supply pipe 1
The liquid paint that has flowed down from the tip of 8 onto the inner peripheral surface of the rear part of the rotating body 2 is made uniform in the circumferential direction as the rotating body 2 rotates, and at the same time, the liquid paint is uniformized in the circumferential direction by the centrifugal force of the rotating body 2 that is rotating at high speed. The liquid paint moves forward along the taper of the inner peripheral surface of the rotating body 2, and the liquid paint that has passed through the tunnel portion 12 and reaches the front inner peripheral surface of the rotating body 2 moves further forward, and finally reaches the inner protrusion 14. It reaches the rear part of the. After this, the liquid paint on the rear surface of the inward protrusion 14 gradually enters the paint discharge hole 1, and the liquid paint that has passed through the inside of the paint discharge hole 1 enters the opening 5 of the paint discharge hole 1.
The rotating body 2, which forms the opening edge of the opening 5, is suddenly blown outward by the action of centrifugal force.
The liquid paint ejected from the front flange 31 by the edge action collides with the inner peripheral surface of the knife edge portion 3 of the cylinder 4, and the liquid paint, which is made into a large thin film by the impact force at the time of this collision, immediately hits the knife edge portion 3. At the same time, the paint particles are electrostatically atomized into extremely fine particles, and synergistically atomized by the action of jet air flowing around the outer periphery of the knife edge portion 3 to promote atomization, and these atomized paint particles are The jet airflow gives an initial velocity, and the electrostatic field causes the object to be coated to fly in the direction of the object 7, and at the same time
At the same time, the annular cylindrical jet airflow that is ejected from the rotating jet nozzle 6 and flows in a spiral manner surrounds the bundle of atomized paint flying in the direction of the object to be coated 7, thereby preventing the atomized paint from being contaminated. This prevents scattering in the required direction, and in the bundle flow of the atomized paint, the atomized paint is well dispersed on a plane perpendicular to the direction of flight, and spread according to the selected cylinders 4, 4a. A uniform coating pattern is formed.

うになる。 In the present invention, the knife edge portion 3 of the cylindrical body 4 is made to protrude forward within a range of 20 mm or less with respect to the opening 5 of the paint discharge hole 1; The amount of forward protrusion is determined in relation to the inner diameter of the arranged cylinder 4, especially the inner diameter of the knife edge portion 3, and as in the cylinder 4 of the illustrated embodiment, the opening diameter of the knife edge portion 3 is determined. If the cylindrical body 4 is small and close to the opening 5 (for example, within a range of several mm), the forward protrusion amount of the knife edge portion 3 must be 10 mm or less; Even if the opening diameter of section 3 is large and the cylinder 4a is quite far from the opening 5 (for example, several cm), the maximum
If the knife edge portion 3 protrudes by 20 mm or more, good atomization as aimed at in the present invention cannot be obtained. That is, in the present invention, most of the liquid paint ejected in the radial direction by the action of centrifugal force from the front flange 32 of the rotating body 2, which is the opening edge of the opening 5, is transferred to the cylindrical bodies 4, 4a near the knife edge portion 3. The liquid paint collides with the inner circumferential surface and becomes a thin film due to the impact force, and this thin liquid paint is supplied to the knife edge part 3 where it is electrostatically atomized, and the liquid paint is electrostatically atomized by the centrifugal force. Fineness can be achieved by making the liquid paint into an extremely thin film using the impact force when the liquid paint thrown off by the action collides with the inner circumferential surface of the cylinders 4, 4a near the knife edge portion 3. Therefore, when atomizing is performed synergistically by electrostatic action and jet airflow action at the knife edge portion 3, the atomized liquid paint particles are compared with those of various conventionally known electrostatic coating devices. It can be made finer to a wider width and form a good coating film. However, in the above embodiment, when attachment A 1 is selected and fitted to rotating body 2,
Since the opening diameter of the knife edge portion 3 of the cylinder 4 constituting the attachment A 1 is small, a coating pattern concentrated in a relatively small area can be obtained.
When the attachment A 2 is fitted, since the opening diameter of the knife edge portion 3 of the cylindrical body 4a constituting the attachment A 2 is large, a coating pattern that spreads over a relatively wide range can be obtained, and a large area can be coated at once. become.

という効果を奏する。 The present invention has a substantially conical cup connected to a rotating shaft and formed on the inner circumferential surface so that paint can be injected, and the inner surface of the cup has a plurality of protruding edges coaxially extending in the direction of the opening of the tip. The distal end of each protrusion is located on the opening side of the tip of the cup according to the protrusion on the outer side from the protrusion on the axial center side, and a jet nozzle is provided at the rear of the outer circumference of the cup, so that the injection nozzle is not injected into the cup. By sequentially ejecting and scattering paint from the inner ridge and colliding with the outer ridge, the paint can be made into a thin film, and this thin film makes it easy to electrostatically finely atomize it from the outer ridge. Furthermore, the atomized paint is further synergistically atomized by the action of the jet air flow jetted around the outer circumference of the cup by the jet nozzle, promoting further atomization, and giving an initial velocity to the paint particles to make them static. A bundle of atomized paint that can be ejected toward the object to be coated with the action of an electric field and that is ejected from a jet nozzle that rotates as the cup rotates and is blown by an annular and cylindrical jet air flow that flows in a spiral shape. This has the effect of preventing the unnecessary scattering of atomized paint in any direction, and as a result, forming a uniform coating pattern.
