本考案は、広角扇形噴霧の噴出による仕上げ塗

Although airless spray painting using an orifice-type flat nozzle has high coating efficiency, atomization tends to be insufficient, tails tend to occur, and most of the paint films produced by wide-angle spraying have mottling. It has disadvantages such as being disadvantageous for finishing paint.

り返えし行なう必要があり、非能率的である。 In order to deal with these drawbacks of airless spray painting, an air nozzle is provided in which a lip-shaped blowhole is formed by crossing a dome-shaped recessed hole and a V-shaped groove, and a fan-shaped air stream is ejected from this air nozzle. In addition, an orifice-type flat paint nozzle was provided inside the air nozzle to eject a fan-shaped spray from behind into the fan-shaped air flow, and as a result, the fan-shaped spray was surrounded by the fan-shaped air flow. A spray gun that was propelled towards the surface to be painted under certain conditions was announced as Utility Model 1987-90762.
This new spray gun that uses pressurized air flow has extremely high coating efficiency and atomization efficiency, and it is easy to prevent tail formation, but the biggest drawback is that the spray angle of the fan-shaped spray is reduced, resulting in a thin film. The width becomes narrow, and therefore, it is necessary to repeat scanning when painting a large area, which is inefficient.

As explained above, according to the present invention, in a spray gun that ejects a fan-shaped paint spray from a flat spray nozzle in a fan-shaped air flow, the groove bottom has a width in order to eject the fan-shaped air flow. By intersecting an internal groove with a roughly V-shaped cross section and an external groove with a width at the bottom of the groove while facing each other in a cross shape, a saddle-shaped fumarole is formed and a wide-angle fan-shaped air flow is ejected. The fan-shaped air flow is arranged so that the spreading direction of the fan-shaped air flow is the same as the spreading direction of the fan-shaped spray ejected from the flat blow nozzle, thereby widening the fan-shaped angle of the fan-shaped paint spray without narrowing it. It is possible to easily form a wide coating film by reaching the surface to be coated while the coating is maintained, and therefore the coating efficiency can be significantly improved. It has the effect of being able to simultaneously achieve prevention, prevention of mist scattering, prevention of mottling, etc.
