DETAILED DESCRIPTION

[0021] The present application will be further clarified by the following examples and figures, which should be understood as merely illustrating the present application and not limiting the scope of the present application. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description are words of convenience and are not to be construed as limiting the present application to any particular orientation. In addition, the words "coupled" and "connected" and variations thereof are used broadly and encompass both direct and indirect connections, as well as fixed and removable connections.

[0022] As Figures 1 to 4 shown, a decorative aluminum plate processing and spraying device includes a base 3, which is a plate member. The upper end of the base 3 is provided with a plurality of conveying rollers 14 equidistantly. The decorative aluminum plate is conveyed by the conveying rollers 14. The upper end of the base 3 is fixedly connected with a housing 5. The housing 5 is provided so that the entire device becomes a relatively closed structure. The inside of the housing 5 is provided with a spraying unit 7 on one side. A paint pipe is provided at one end of the spraying unit 7, which is used to connect a device for supplying paint. The lower end of the spraying unit 7 is provided with a plurality of spray heads 8, which spray atomized paint onto the decorative aluminum plate.

[0023] The upper part of the shell 5 is fixedly connected with the annular circulating air duct 6. According to the height of the air duct 6 and the need of the spraying operation, the air duct 6 can be placed inside the shell 5 or at the upper end of the shell 5. In the illustration, the upper part of the air duct 6 is above the shell 5, and the lower part of the air duct 6 is below the shell 5. A plurality of air outlets 9 are arranged at one side of the lower end of the air duct 6, and the air outlets 9 are inclined to the conveying direction of the decorative aluminum plate, that is, the decorative aluminum plate is conveyed towards the air outlets 9. Air inlets 11 are arranged at the other side of the lower end of the air duct 6. The air sent out from the air outlets 9 enters the air inlets 11, realizes circulation, and disturbs the atomized paint floating in the air, reduces the overflow of the paint. The air inlets 11 and the air outlets 9 are provided with blocking baffles 13, and the blocking baffles 13 block the air duct 6 upwards. The blocking baffles 13 make the air flow closer to the decorative aluminum plate, and the residual paint in the air adheres to the decorative aluminum plate. In addition, the blocking baffles 13 block the air duct 6, realize the air flow in the air duct 6, send out from the air outlets 9, and suck in from the air inlets 11. The circulation is used to disturb the air flow in the shell 5 and reduce the escape of the paint.

[0024] A first motor 10 is fixedly connected to the upper end side wall of the air duct 6. A cross-flow fan is arranged in the air duct 6, and the output end of the first motor 10 is fixedly connected with the cross-flow fan. When the first motor 10 is started, the cross-flow fan rotates, thereby realizing the circulation of air.

[0025] A filter screen 4 is arranged at one side of the upper end of the air duct 6. If the paint is easy to adhere, the filter screen 4 is arranged to prevent the air duct 6 from being blocked, and the paint in the air is intercepted. A handle is arranged at one side of the filter screen 4. If the filter screen 4 is blocked, the handle can be used to remove and replace the filter screen 4. A collection tray 12 is arranged below the air inlets 11. During the circulation process, more or less paint flows out of the air inlets 11. Therefore, the collection tray 12 is arranged to prevent the paint from directly dropping on the decorative aluminum plate.

[0026] Openings are arranged on the front and back sides of the shell 5, which are used for the decorative aluminum plate to enter and exit. The entering opening is located at one side of the air inlets 11, and the sending opening is located at one side of the air outlets 9. A door 2 is arranged at the opening, which blocks the opening to ensure that the decorative aluminum plate enters the inside of the shell 5, thereby reducing the escape of the paint. A sliding groove 18 is arranged on the inner wall of the shell 5, and the two sides of the door 2 are slidingly fitted in the sliding groove 18. A push block is arranged on the front of the door 2 to realize the lifting of the door 2 by pushing up and down. In addition, an elastic material such as rubber pad is arranged between the door 2 and the sliding groove 18 to ensure that there is sufficient friction between them to keep the door 2 stationary.

[0027] A plurality of supporting legs 1 are fixedly connected to the lower end of the base 3, which support the entire device.

[0028] The lower end of the base 3 is fixedly connected with a second motor 15, the output end of the second motor 15 and the rotating shaft of one of the conveying rollers 14 are fixedly connected with a belt pulley 17, and the belt pulley 17 is sleeved with a belt 16. The second motor 15 is started, the belt 16 is transmitted through the belt pulley 17, and the rotation of the conveying roller 14 is realized.

[0029] The technical means disclosed in the scheme of the application is not limited to the technical means disclosed in the above-mentioned embodiments, and also includes the technical scheme composed of any combination of the above technical features.
