Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of aluminum profile production, and particularly relates to a hanging tool protection device for a powder spraying room of an aluminum profile vertical coating production line. BACKGROUND

[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 in aluminum material factories due to its high efficiency and large capacity. Powder spraying uses the principle of electrostatic spraying to adsorb dry powder-like substances on metal aluminum profiles, and after baking at a temperature above 200 DEG C, the powder-like substances solidify into a layer of about 60 microns thick, solid and bright coating. The traditional vertical spraying production line needs to complete the spraying of both sides of the workpiece through two powder spraying rooms. Therefore, during the conveying process of the aluminum profile, the aluminum profile is generally arranged vertically, so a hanging tool for fixing the aluminum profile is generally arranged on the conveying chain. After the hanging tool is conveyed to the powder spraying room along the conveying chain, the aluminum profile is sprayed by a spray gun. Dry powder particles will diffuse in the powder spraying room, and some powder may fall into the chute and the conveying chain. Therefore, the existing technology has the problem that powder is easy to accumulate on the chute and the conveying chain, thereby affecting the smoothness and stability of the movement of the hanging tool.
