Description

Technical Field

[0001] The invention belongs to the technical field of profile processing, and in particular relates to a paint spraying and drying device for aluminum alloy profiles. Background Art

[0002] Alloy profile is an alloy material with aluminum as the main component. Aluminum rods are obtained through hot melting and extrusion to obtain aluminum materials with different cross-sectional shapes. However, the proportion of the added alloy is different, and the mechanical properties and application fields of the produced industrial aluminum profiles are also different. It is the most widely used type of non-ferrous metal structural material in industry.

[0003] Existing aluminum alloy profile paint spraying and drying devices usually use heating and blowing methods to accelerate the evaporation of water in the paint surface, so as to achieve the purpose of quickly drying the paint surface. However, in the prior art, the paint surface is usually blown directly. At this time, since the paint surface is not dry yet and still has a certain fluidity, the wind force will drive the surface movement of the paint surface, thereby generating wavy patterns, making some products scrapped.
