Description

Technical Field

[0001] The utility model relates to the technical field of powder coatings, in particular to a novel powder coating screening device. Background Art

[0002] Ultrafine powder coating is a solvent-free solid powder coating in the form of fine powder. This coating is made of special resin, pigment, filler, curing agent and other additives mixed in a certain proportion, and then prepared by hot extrusion and crushing and screening processes. Since it does not use solvents, it has the characteristics of harmlessness, high efficiency, resource saving and environmental protection. The screening of ultrafine powder coating is to ensure the quality, performance and safety of the coating to meet the needs of the coating process and improve the overall quality of the product. During the screening process of the powder coating screening device, the powder will float out from the inlet, affecting the working environment. At the same time, most screening devices use water washing to clean the inside of the screening device. However, the coating will fuse when it meets water. The fused coating powder during the cleaning process will adhere to the inner wall of the screening device and stain the inner wall of the screening device, resulting in poor cleaning effect.

[0003] In order to solve the above problems, a utility model patent with publication number CN213494878U discloses a powder coating screening device. The bottom of the feed hopper is designed to be bent to reduce the powder floating out of the feed hopper during screening. At the same time, an ultrasonic generator is used to emit ultrasonic waves to shake off the powder attached to the screening box, thereby avoiding water washing causing the coating to adhere to the inner wall of the screening box.

[0004] There are still some shortcomings in the use of the above-mentioned powder coating screening device. When screening ultra-fine powder coating, due to the fine particle size of the powder coating, it is not convenient to shake the powder coating during screening, and the powder coating often clumps, which makes it inconvenient to roll the powder coating before screening, which can easily cause the screen plate to be blocked, reducing the continuity of screening, thereby reducing the screening efficiency and prolonging the screening time.
