DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0022] Example

[0023] See also Figures 1 to 5The powder spraying room structure with vertical side exhaust in this embodiment includes a manual section powder spraying room 1, a side air duct 11, a powder spraying room 12 and a bottom air duct 13. The powder spraying room 12 is installed on one side of the manual section powder spraying room 1. The inner walls on both sides of the powder spraying room 12 are fixed with side air ducts 11 by welding. The bottom of the powder spraying room 12 is installed with a bottom air duct 13, which is connected to the external vacuum negative pressure source. The vertical side air duct is formed by adding a bottom hole and a door to the PVC board block to form a vertical air duct, which is combined with the air duct at the bottom of the powder spraying room to enter the recovery system. The workpiece is set in the powder spraying room 12 for powder spraying and adhesion.

[0024] The manual powder spraying room 1 in this embodiment is provided with a powder supply end 14 , the output end of the powder supply end 14 is connected through a plurality of fixed pipes 15 , and the bottom of the fixed pipe 15 is fixed with a nozzle 6 by welding.

[0025] In this embodiment, there are three nozzles 6 , which are distributed in a circle around the center of the powder spraying room 12 . The powder is sprayed inside the powder spraying room 12 through the three nozzles 6 , thereby improving the uniformity of the spraying.

[0026] The nozzle 6 in this embodiment has a cylindrical chamber inside, and an open sleeve 7 is slidably embedded in the inner wall of the chamber. A bottom plate 9 is installed at the bottom of the nozzle 6, and cover plate 2 4 and cover plate 1 5 are correspondingly installed on both sides of the nozzle 6. Large-aperture nozzles 41 are evenly installed on one side of cover plate 2 4, and small-aperture nozzles 51 are evenly installed on one side of cover plate 1 5. By adjusting the direction of the open sleeve 7, the internal spraying powder will flow outward from the inside of cover plate 2 4 or cover plate 1 5, so that the powder will be sprayed out from the small-aperture nozzle 51 or the large-aperture nozzle 41 in different forms, which is convenient for use on different types of workpieces.

[0027] The top of the open sleeve 7 in this embodiment is fixed with an adjustment shaft 2 by welding. The adjustment shaft 2 is connected to the external torque. The direction of the open sleeve 7 is controlled by adjusting the shaft 2, which facilitates the adjustment of the spraying mode.
