Abstract
Description
Technical Field
[0001] The invention relates to the field of furniture production, in particular to a surface spraying process for furniture panels. Background Art
[0002] In order to improve the corrosion resistance and aesthetics of furniture, a variety of coatings are usually sprayed on the surface of furniture panels. In actual processing, in addition to common flat panels, some arc-shaped panels used for furniture decoration also need to be sprayed. In order to ensure the uniform thickness of the coating on the surface of the arc-shaped panels, the nozzle needs to maintain a constant distance from the arc surface of the arc-shaped panel, and the nozzle needs to move in a uniform circular motion around the surface of the panel. In actual production, the paint sprayed by the nozzle has a certain angle with the surface of the arc-shaped panel, and the sprayed paint will be sprayed obliquely onto the surface of the arc-shaped panel, resulting in the coating in the spraying area being thicker on one side and thinner on the other side, making the coating at the edge of the arc-shaped panel unevenly sprayed, with low spraying quality and high loss.
