An air inlet 302 is formed for this purpose, and an outlet 303 can be formed to discharge the paint by air pressure. At this time, the paint inlet 301 and the air supply unit 200 are provided at the top of the shoe basket 300 close to the moving object (not shown), and the outlet 303 is provided at the bottom of the shoe basket 300 so as to be close to the ground. It can be provided.

Meanwhile, one feature of the present invention is that when the paint is discharged to the ground by compressed air, it is configured to be discharged uniformly and at a positive pressure. The air distribution plate 400 and the paint distribution plate 500 are provided to implement one feature of the present invention.

The air distribution plate 400 may form a plurality of micropores 450 evenly distributed at regular intervals within the area according to the shape of the air injection port 302. That is, when the air inlet 302 is square, the plurality of micropores 450 are distributed to fit the square-shaped area of the air inlet 302 and can be arranged in rows and columns at regular intervals, and the air inlet ( When 302) is circular, a plurality of micropores 450 are distributed according to the circular area of the air inlet 302 and can be arranged in rows and columns at regular intervals.

At this time, the paint transfer pipe 110 is formed in a cross (+) shape, and a first flange portion 111 is formed on one side to which a connection pipe (not shown) extending from a paint supply tank (not shown) can be coupled. A second flange portion 112 may be formed on the other side, and a motor mounting portion 113 for rotating the transfer screw 120 provided inside the paint transfer pipe 110 may be formed on the upper side.

Here, the first flange portion 111 is a connector to which the paint transfer pipe 110 is fixed in order to adjust the angle of the shoe basket 300 in addition to connecting the connector (not shown) with the paint transfer pipe 110. It may be configured to rotate about (not shown), and for this purpose, the first flange portion 111 is a first flange (not shown) for connecting a connector (not shown) with the paint transfer pipe 110. And it may be configured to include a bearing (not shown) to smoothly rotate the paint transfer pipe 110.

In addition, the second flange portion 112 is an external connection pipe ( (not shown) may be configured to include a second flange (not shown) for opening and closing the other side of the paint transfer pipe 110.

That is, the second flange is normally fastened to the paint transfer pipe 110 and closes the other side of the paint transfer pipe 110, but if a problem occurs in the paint supply through the first flange portion 111 or the paint transfer pipe ( 110) When internal cleaning is required, it can be opened to connect an external connector (not shown) to the paint transfer pipe 110, and paint or cleaning agent can be supplied into the paint transfer pipe 110 through the external connector. there is.

Meanwhile, the motor 114 is mounted on the motor mounting portion 113 provided on the upper side of the paint transfer pipe 110 as described above, and the transfer screw 120 is connected to the motor 114 and is used within the paint transfer pipe 110. It can be formed in a length and rotated by the rotation of the motor 114.

At this time, the motor 114 may be directly connected to the transfer screw 120, but on the other hand, it may be connected through the coupler 115 as shown in the drawing, and although not shown, a bearing or Seals, etc. are provided to facilitate rotation and prevent oil leakage.

In addition, a protective cover 116 may be provided between the motor 114 and the paint transfer pipe 110 to protect the coupler 115, bearings, seals, and a portion of the transfer screw 120 described above.

The transfer screw 120 is provided inside the paint transfer pipe 110 and rotates by the motor 114, and moves into the paint transfer pipe 110 through the first flange part 111 or the second flange part 112. The delivered paint can be rotated and transferred to the shoe basket 300. At this time, the rotational force of the transfer screw 120 is adjusted by the motor 114 and the transfer amount of the paint and the discharge amount and discharge pressure to the shoe basket 300 can be adjusted.

The length of the transfer screw 120 is not limited, but may preferably extend to the inside of the shoe basket 300, and may be supported by the support plate 121 provided inside the shoe basket 300. Here, the support plate 121 may be formed to have a length in a direction perpendicular to the longitudinal direction of the transfer screw 120 to stably support the transfer screw 120.

Meanwhile, the support plate 121 may be formed to have a length that extends from one side of the shoe basket 300 to the entire other side, as shown in FIG. 5 . Through this, the paint transferred from the transfer screw 120 can be guided only downward. At this time, a paint dispersion fan 122 may be provided between the transfer screw 120 and the support plate 121, which is coupled to the axis of the transfer screw 120 and rotates by sharing the rotational force of the transfer screw 120. The paint dispersion fan 122 rotates according to the rotation of the transfer screw 120, and can evenly distribute the incoming paint by dispersing it to the fan blades.

The first hot wire heater 130 is a heater wound in a coil shape on the outer surface of the paint transfer pipe 110, and may be configured to receive electricity from an electricity supply unit (not shown) and generate heat. The heat supplied from the first hot wire heater 130 is transferred to the paint transfer pipe 110 to maintain a temperature above a certain level to prevent the paint from hardening. Here, the electricity supply unit (not shown) may be a vehicle battery or may be provided separately.

A heater cover 131 may be provided outside the first hot wire heater 130 to primarily protect the first hot wire heater 130, and as shown in FIG. 6, a heater cover 131 may be provided outside the heater cover 131. A protective cover 140 may be provided to secondaryly protect the heater 130. At this time, a gap is generated between the heater cover 131, which primarily protects the first hot wire heater 130, and the protective cover 140, which secondarily protects the first hot wire heater 130, to form an air layer, and this air layer is the first hot wire heater (130). 130), heat transfer to the outside is blocked as much as possible, and the temperature of the paint can be maintained very well.

The air supply unit 200 may include an air compressor (not shown), an air regulator (not shown), an air valve 210, and a backflow prevention check valve (not shown). Here, the air valve 210 is connected to an air compressor (not shown) to receive compressed air, and can discharge the compressed air toward the air distribution plate 400 and deliver it to the inside of the shoe basket 300.

The air regulator (not shown) can measure and control the air pressure of the compressed air discharged from the air valve 210 into the shoe basket 300, and the backflow prevention check valve (not shown) opens and closes according to the air pressure, and the air valve ( Compressed air to be discharged through 210) can be prevented from flowing back into the air compressor (not shown).

As shown in FIG. 7, the shoe basket 300 may include an upper end 310, an upper inclined part 320, a lower inclined part 330, and a lower end 340.

Specifically, the upper part 310 is where the air inlet 302 is provided, and the air supply unit 200 can be connected to it. That is, the upper part 310 may be provided with an air distribution plate 400. Additionally, the upper end 310 may be formed to allow compressed air to flow in vertically or may be formed horizontally. Through this, the air distribution plate 400 is also maintained horizontal, and the compressed air flowing in in the vertical direction can be uniformly distributed and injected into the plurality of micropores 450 of the air distribution plate 400.

The upper inclined portion 320 may be provided with a paint inlet 301. That is, the upper inclined portion 320 can be connected to the paint supply unit 100 to provide a passage to receive the paint. At this time, the upper inclined portion 320 may extend from the upper upper portion 310 to form an incline outward and downward, and the transfer screw 120 may introduce the paint in a direction perpendicular to the upper inclined portion 320 so that the paint is It can be allowed to flow in an inclined direction with respect to the shoe basket 300.

The lower inclined part 330 extends from the upper inclined part 320 and is configured to form an inward downward slope, so that the paint flowing in through the paint inlet 301 can flow in an inclined direction.

Here, the paint distribution plate 500 may be mounted horizontally on the lower slope portion 330, through which the paint flowing down the bottom slope portion 330 flows to the paint distribution plate 500 as described above. It can be dispersed through a plurality of perforations 550 and discharged toward the outlet 303 under positive pressure.

Meanwhile, the plurality of perforations 550 of the above-described paint distribution plate 500 may gradually increase in diameter as shown in FIG. 8A as the distance from the lower inclined portion 330 of the shoe basket 300 increases. Through this, less paint flowing down along the lower slope 330 is discharged closer to the lower slope 330, where relatively large pressure is applied, and less paint is discharged from the lower slope 330, where pressure is relatively small. It may be possible to discharge more uniformly at more positive pressure while allowing less and more to be discharged.

Additionally, the plurality of perforations 550 may gradually increase in diameter as they move from the center of the shoe basket 300 to the side, as shown in FIG. 8B. Through this, as in the above-mentioned principle, the paint can be discharged relatively more uniformly at a positive pressure by spreading it out to the sides rather than clumping in the center.

The lower part 340 is provided with an outlet 303 and can be extended from the lower inclined part 330 to form a horizontal position. Through this, the paint flowing into the upper inclined portion 320 of the shoe basket through the paint supply unit 100 flows through the lower inclined portion 330 and is compressed by the static pressure flowing vertically through the upper portion of the shoe basket 300. It may fall to the ground while being discharged by air through the outlet 303.

That is, the shoe basket 300 may be configured so that the compressed air pushes the paint flowing in in an oblique direction in a vertical direction and causes it to fall vertically toward the discharge port 303. Through this, in the present invention, the compressed air is used only for discharging the paint without blocking the discharge of the paint, so that the discharge of the paint can be smoother.

Meanwhile, a second hot wire heater 350 that receives electricity and generates heat may be provided inside the shoe basket 300. That is, in the present invention, a first hot wire heater 130 is provided in the paint transfer pipe through which the paint is transferred, and a second hot wire heater 350 is provided in the shoe basket 300 where the paint is temporarily accommodated, so that the paint is cured. It can be prevented and discharged by maintaining a certain temperature.

The metal mesh network 1000 may be interposed between the paint transfer pipe 110 and the shoe basket 300, that is, in the paint inlet 301. The metal mesh network 1000 disposed in the paint inlet 301 is a means for uniformly dispersing and supplying the paint delivered from the transfer screw 120 when it is supplied to the shoe basket 300, and the air distribution plate 400 In conjunction with the paint distribution plate 500, the paint may be uniformly discharged under constant pressure.

In addition, the present invention may be configured to further include a paint discharge control unit 600 provided at the discharge port 303. This will be explained with reference to FIGS. 9 to 12B.

Referring to FIGS. 9 to 12B, the paint discharge control module 600 may be mounted at the bottom of the discharge port 303 and configured to control discharge of paint. At this time, the discharge of the paint may be one or more of the following: whether the paint is discharged, the discharge direction of the paint, or the discharge of the paint.

The paint discharge control module 600 may be configured to include a mounting plate 610, a rotating body 620, and a rotation control unit 630 to control the discharge of paint.

Specifically, the mounting plate 610 is a plate fixed to the bottom of the outlet 303 and can form an extended outlet 615 with an area corresponding to the outlet 303. That is, when the outlet 303 is rectangular, the extended outlet 615 may be rectangular and have the same area and shape as the outlet 303. The mounting plate 610 forming the extended outlet 615 may be fastened to the lower end 340 of the shoe basket 300 so that the outlet 303 and the extended outlet 615 extend and coincide with each other to form one passage.

The rotating body 620 is provided inside the mounting plate 610 and can form an adjustment outlet 625 with an area corresponding to the outlet 303 and the extended outlet 615. This rotary body 620 can be rotated by the rotation control unit 630, and when rotated by the rotation control unit 630, an angle difference between the control outlet 625 and the extension outlet 615 occurs, causing the paint to You can open or close the discharge, control the discharge direction of the paint, or adjust the discharge amount of the paint.

The rotation control unit 630 is provided to rotate the rotating body 620, and is axially coupled to the cylinder 631, which moves the piston vertically in the upward/downward direction, according to the movement of the piston. It rotates, but may be configured to include a connection bar 632 connecting the piston and the rotating body 620.

Accordingly, the connecting rod 632 can rotate according to the piston movement of the cylinder 631, and this rotation also causes the rotating body 620 to rotate, creating an angle difference between the extension outlet 615 and the control outlet 625. can occur. Using this, the present invention can control the discharge of paint through rotation of the paint discharge control module 600, such as controlling whether the paint is discharged, the discharge direction of the paint, and the amount of paint discharge.
