Color steel plate plastic coating equipment with transverse high-voltage static bar

[0023] Horizontal high-voltage electrostatic bar color steel plate plastic coating equipment, such as Figure 1 to Figure 4 As shown, it includes an electrostatic bar 1 and a spray gun 2 , the spray gun 2 is located above the steel plate 4 , and the electrostatic bar 1 is parallel to the plane where the steel plate 4 is located. The direction of the current in the electrostatic bar 1 is perpendicular to the moving direction of the steel plate 4 . The electrostatic bar 1 is arranged above the steel plate 4 .

[0024] A screen 3 is arranged between the spray gun 2 and the steel plate 4 . After the spray gun 2 sprays for a long time, powder accumulation will inevitably occur on the spray gun 2. The screen 3 can prevent the powder accumulation on the spray gun 2 from falling directly on the steel plate 4, thereby affecting the spraying effect of the steel plate 4. Similarly, the electrostatic bar 1 is also arranged above the screen 3 .

[0025] The mesh size of the sieve 3 is 5-50

[0030] The difference between this embodiment and embodiment 1 is that the static bar 1 is arranged between the screen 3 and the steel plate 4 . The electrostatic bar 1 is arranged obliquely, and the direction of the current in the electrostatic bar 1 forms an included angle with the moving direction of the steel plate 4 . That is, the direction of the current in the electrostatic bar 1 is different from the moving direction of the steel plate 4. There are four electrostatic bars 1, and the four electrostatic bars 1 are arranged in parallel on the same plane. The powder sprayed from the spray gun 2 passes through the screen 3 and enters the static electricity The electrostatic area of ​​the rod 1, so that the powder is charged, and when the powder contacts the steel plate, electrostatic adsorption occurs, thereby completing electrostatic spraying.
