In the manufacturing process of powder coating, screening is a key step. The use of powder coating screening devices can not only improve production efficiency, but also improve product quality. Therefore, it plays an important role in the coating production process. Powder coating screening devices can grade coatings. Different industries have different requirements for coatings. Some require coating particles with larger particle sizes, while others require coating particles with smaller particle sizes. By selecting appropriate screen apertures, powder coatings can be divided into different size ranges in the screening device to meet the needs of different industries. This not only improves the utilization rate of the coating, but also reduces the waste of the coating. It can also improve the uniformity of the coating, thereby optimizing the coating manufacturing process, improving product quality, and meeting the needs of different industries for coatings.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional multi-stage powder coating screening device, most of the screened powder is taken out by taking out the screen plate. Most of the devices have fixed structures, and it is inconvenient to take out each level of coating, which often takes a certain amount of time. The powder may be mixed again when it is taken out.

When taking out each level of powder coating, the first motor is used to drive the screw on the fixed plate to rotate, and the rotating screw drives the first connecting block to move upward, so as to move the protective shell upward and collect the powder coating remaining on the surface of the first sieve plate. Then, the handle is used to drive the cover plate to rotate, open the main body of the screening device, and take out the powder coating remaining on the arc-shaped sealing plate. Finally, the powder coating obtained after screening is collected and stored in the collecting hopper, and the coating is discharged through the discharge pipe, so as to solve the problem that the operation of taking out the screened powder in most multi-stage powder coating screening devices is cumbersome, which affects the screening quality of the device, and enhance the flexibility of the device;

[0015] 3. During the screening operation, the main body of the screening device is fixedly supported by the support rod, and the protective shell is embedded in the sealing groove. The powder coating is poured into the lower hopper. At the same time, the telescopic electric telescopic rod drives the vibration spring to vibrate continuously, thereby driving the first screen plate to vibrate continuously. The powder coating is initially screened through the first screen plate, and the screened powder falls into the shaking bucket. The remaining large pieces of powder remain on the surface of the first screen plate. The arc-shaped sealing plate is used to receive the powder coating screened by the first screen plate, and the second shaft is driven to rotate by the servo motor. Rotating the second shaft drives the shaking bucket to shake back and forth. At the same time, the first shaft is driven to rotate to ensure stable shaking of the shaking bucket, and the powder coating is further screened through the arc-shaped screen plate.
