Description

Technical Field

[0001] The utility model belongs to the technical field of powder spraying, and in particular relates to a negative pressure open type aluminum profile powder spraying device. Background Art

[0002] Aluminum profiles are widely used in various industries. During the production process, they need to be sprayed. At present, electrostatic powder spraying has become the most important treatment method in the industry among aluminum profile surface treatment manufacturers, and vertical powder spraying is widely used by aluminum factories due to its high efficiency and large production capacity. Vertical powder spraying uses powder spraying equipment to spray materials onto the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating. The powdery coating is baked and leveled to form a final coating with different effects (different types of powder coatings). The spraying effect of powder spraying is superior to the painting process in terms of mechanical strength, adhesion, corrosion resistance, and aging resistance, and the cost is also lower than that of painting with the same effect.

[0003] Chinese patent announcement No. CN202221950847.2 discloses a vertical powder spraying device for aluminum profile spraying, comprising a device body, a powder shielding cover is provided at the powder outlet end of the device body, and the powder shielding cover is detachably connected to the device body by a connecting piece, a powder collecting cover is fixedly provided in the middle of the powder shielding cover, and a conduit is provided at the end of the powder collecting cover away from the device body, etc., wherein it realizes the vertical powder collection effect, but the powder that is not collected by the negative pressure from the powder shielding cover will fall below the powder collecting cover, and may also be scattered in the air during the falling process of the powder, thereby causing a certain impact on the environment, and the fallen and accumulated powder needs to be manually cleaned and recycled, thereby consuming a certain amount of manpower. In addition, the arc-shaped powder shield has poor guidance, which will affect the effect of negative pressure powder absorption. Therefore, a negative pressure open aluminum profile powder spraying device is needed to solve the above problems. Utility Model Content
