Example Embodiment

[0015] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0016] Such as figure 1 As shown, a fully-sealed spray gun nozzle for a powder spraying chamber, the upper end of which is connected with the top 1 of the powder spraying chamber, the upper flexible belt 2 is fixed on the winding roller 4, and the upper flexible belt 2 is elastically unwinded by the winding roller 4 . The lower flexible belt 3 is fixed on the lower winding roller 5, and the lower winding roller 5 unwinds and rewinds the flexible belt 3 elastically. The electrostatic dust spray gun 6 is fixed between the upper flexible belt 2 and the lower flexible belt 3, and is driven by the reciprocating machine to move up and down to spray powder on the workpiece in the powder spraying chamber.

[0017] Such as figure 2 As shown, the spray gun 6 is fixed between the upper flexible belt 2 and the lower flexible belt 3 by using the rotating bolt 12 ...

Abstract

The invention relates to a full-closed automatic spray gun mouth in the side of a powder spraying booth. In the electrostatic powder coating industry, a traditionally designed spray gun mouth in the side of a powder spraying booth is open during spray coating, and the power of a draught fan is very high in order not to overflow powder. In the process of clearing for color changing, the powder overflowing out of the automatic gun mouth will pollute the environment as well. According to the full-closed automatic spray gun mouth, two flexible belts (containing PU, PVC and the like) are adopted as pull curtains, and an upper flat belt and a lower flat belt are wound around rollers respectively, wherein coil springs (or clockwork springs or other energy storage mechanisms) are installed on the rollers; the flat belts reciprocate in the vertical direction along with a spray gun during spray coating and can close the spray gun mouth no matter where the spray gun moves. In the process of clearing for color changing, dust in the powder spraying booth will not overflow, and therefore pollution is reduced. In this way, the power of a motor can be lowered, so that pollution is further reduced. Accordingly, the spray gun mouth is a novel environmentally-friendly and energy-saving design for the powder spraying booth and is suitable for various powder spraying booths.

Description

technical field [0001] The spray gun port of the electrostatic powder spraying room according to the present invention can fully seal the side spray gun port so as to achieve the spray gun port of the environment-friendly powder spraying room with low energy consumption and no flickering. Background technique [0002] When calculating the exhaust air volume of the electrostatic powder spraying room, in order to ensure that the powder does not overflow at each opening, the average wind speed of each opening must be greater than 0.65 m / s, so the larger the opening, the greater the exhaust air volume of the fan required. The greater the power. The opening width of the automatic gun on the side of the powder spraying room must generally be at least 100mm, and the height is generally 250-300mm larger than the height of the workpiece. The higher the workpiece, the greater the air volume of the fan required. The number of automatic gun openings on the side of the powder spraying r...
