Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile production, and more specifically to a vertical spraying device for aluminum profiles. Background Art

[0002] In the field of aluminum profile surface treatment, electrostatic powder spraying has become the most important treatment method in the industry, and vertical powder spraying is widely used by aluminum plants due to its high efficiency and large production capacity. Powder spraying uses the principle of electrostatic spraying to adsorb dry powder on metal aluminum profiles. After being baked at a high temperature of more than 200°C, the powder solidifies into a layer of about 60 microns thick, solid and bright coating. In the field of aluminum profile surface treatment, electrostatic powder spraying has become the most important treatment method in the industry, and vertical powder spraying is widely used by aluminum plants due to its high efficiency and large production capacity. Powder spraying uses the principle of electrostatic spraying to adsorb dry powder on metal aluminum profiles. After being baked at a high temperature of more than 200°C, the powder solidifies into a layer of about 60 microns thick, solid and bright coating. For example, the Chinese patent application publication number CN116251700A discloses a vertical aluminum spraying equipment, which includes a conveying mechanism for mounting and transporting aluminum profiles, and a spraying mechanism for electrostatic powder spraying of aluminum profiles is arranged on the side of the aluminum profile; a limiting mechanism is arranged directly below the conveying mechanism, and the limiting mechanism includes a limiting bar connected to the bottom end of the aluminum profile, and a limiting block is arranged at the lower part of the limiting bar through a connecting rod; and a limiting base is arranged parallel to the conveying mechanism directly below the aluminum profile. In this patent structure, the spraying mechanism adopts the form of a horizontal row of spray guns, and the whole row of spray guns drives the vertical aluminum profile to spray up and down through a lifting mechanism. The spray guns are all arranged horizontally in parallel, which leads to uneven force, causing great wear of the moving parts, a large reciprocating stroke of the spray gun, and a close distance between the horizontally parallel spray guns, which affects the discharge effect of the spray gun itself, resulting in low density of the powder coating, thereby affecting the surface effect and powder application rate of the coating. In addition, if the distance between the spray guns is too close, the spray gun spray width will be affected, which will in turn affect the coating efficiency. The same number of spray guns occupies a larger area; the spraying efficiency is affected by the number of spray guns in parallel. If the spraying efficiency is to be improved, a powder room with a large area is required, which increases the production cost. Therefore, it is necessary to further improve the existing technology.
