Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate spray painting, in particular to an automatic spray painting device on the surface of an aluminum plate. Background Art

[0002] Aluminum sheet is a common metal sheet with a wide range of uses in daily production and life, such as building exteriors, interior decoration, etc. In order to make the aluminum sheet more beautiful and improve its corrosion resistance, the surface of the aluminum sheet is generally sprayed with paint. Traditional painting processes mostly use manual painting methods, which require operators to hold a paint spray gun to spray paint, and rotate the turntable that clamps the aluminum sheet during the painting process to complete the painting of each side of the aluminum sheet. However, the manual painting method can easily cause uneven spraying on the surface of the aluminum sheet, thereby affecting its quality and beauty. Existing technology has gradually turned to automated painting, which solves the problems of uneven manual painting and high labor costs.

[0003] After searching the existing public patent number: CN202320081561.3, the public patent name is: A surface painting device for aluminum plate processing, including a drive box, a protective box is fixedly connected to the top of the drive box, a paint tube is fixedly connected to the left side of the top of the inner cavity of the protective box, the top of the paint tube is connected to a conduit, the top of the conduit extends to the outside of the protective box, the left and right sides of the bottom of the paint tube are evenly connected to paint nozzles, and a drying box is embedded on the right side of the top of the protective box. The utility model can facilitate the spraying and drying of aluminum plates by arranging a drive box, a protective box, a paint tube, a paint nozzle, a drying box, a mounting plate, a heating resistor wire and a fan. By arranging a drive assembly, it can facilitate the moving and feeding of aluminum plates. By arranging the above structure, the paint spraying device has the advantage of having a drying function when in use, which solves the problem that the above-mentioned paint spraying device does not have a drying function when in use, thereby avoiding affecting the processing efficiency.

[0004] However, the above device can often only spray one side of the aluminum plate. When the other side of the aluminum plate needs to be sprayed, the aluminum plate still needs to be moved and turned over, which is inconvenient to use. Utility Model Content
