果、粉体塗料供給量の増大が不可避的である。 For powder coating, for example, when applying powder paint to the inner surface of a tube, conventionally, as shown in FIG. is moved back and forth into the pipe P'. In this case, if the inner diameter of the pipe P', which is the object to be painted, becomes larger, it is necessary to increase the paint projection distance.Increasing this projection distance requires increasing the air flow rate of the pneumatic pipe 1', and therefore the air pressure. As a result, an increase in the amount of powder paint supplied is inevitable.
このように従来の粉体塗装装置においては、塗
料の投射距離と供給量とを独立的に設定すること
が困難であり、塗装条件の設定が至難である。 As described above, in the conventional powder coating apparatus, it is difficult to independently set the paint projection distance and the supply amount, and it is extremely difficult to set the coating conditions.
本考案に係る粉体塗装装置は上述の不利を解消

The present invention is characterized in that nozzles are provided facing each other, and paint jetting vanes disposed at the tip end of the air pipe are supported on the wind blowing rotor.
以下、図面により本考案を説明する。 The present invention will be explained below with reference to the drawings.

て、気送管１の先端口１１に配設されている。 In Fig. 2, 1 is a powder coating pneumatic pipe;
The tip opening 11 is widened in a tapered shape. The air flow rate and therefore the air pressure in this pneumatic tube 1 can be adjusted as appropriate. Reference numeral 2 denotes a wind blowing rotary body, in which several blades 22 are mounted inside an open casing 21, and the casing 21 is rotatably supported on the outer periphery of the tip of the air pipe 1 by means of a bearing 3. 4 is a nozzle, and the wind blowing rotating body 2 receives pressure of the jet air from the nozzles 4, . . . in the blades 22, . The air flow rate and therefore the air pressure of the nozzles 4, . . . can be adjusted as appropriate. 5 is a paint projection blade, and there are several blades 5 on the back of the conical cone 21.
2,... are installed. The projection blades 5 are supported by the wind blowing rotating body 2 by shaft rods 6, .

調節できる。 In the above, the powder paint is sent through the pneumatic pipe 1, and the amount of paint supplied is
Can be adjusted by air pressure. Further, the projection distance of the powder coating can be adjusted by the centrifugal force received from the powder coating projection blades 5, and therefore by the rotational speed of the blades 5, and this rotational speed is controlled by the air pressure of the nozzles 4,... Can be adjusted. Therefore, the air pressure in the pneumatic pipe 1 and the air pressure in the nozzles 4, . It can be adjusted independently without being affected.

５Kg／cm2の範囲内でそれぞれ調節すればよい。 If the object to be coated is the inner surface of a cast iron pipe, reduce the coating amount.
Assuming 5.0 to 20.0 Kg/min, the air pressure of the above pneumatic pipe is 0.5 to 3.0 Kg/ cm2 , and the air pressure of the nozzle is 0 to 3.0 Kg/cm2.
You can adjust each within the range of 5Kg/cm 2 .
上述した通り、本考案に係る粉体装料装置によ
