Description

Technical Field

[0001] The utility model relates to the technical field of paint sieving, in particular to a powder paint sieving device. Background Art

[0002] Powder paint is a very common form of paint, which consists of solid particles and a fluid binder. During the construction process, powder paint needs to be sprayed and baked through specific equipment to form a uniform and stable coating. In the preparation process of powder paint, the control of particle size is a very important link, and sieving is one of the commonly used means.

[0003] Currently, when powder paint is sieved, a sieving device is needed for auxiliary operation.

[0004] A prior art paint powder rapid sieving device with the publication number of CN218574254U includes a support frame. The outer shell is provided with a support ring, and a bracket is arranged on the support ring. The bracket is connected to the support frame through a telescopic column and an insertion column. The support frame is provided with a vibration motor, and the output end of the vibration motor is fixedly connected to the bracket. The inner shell is arranged inside the outer shell. The outer shell is provided with a rotary motor, and the output shaft of the rotary motor is connected to a rotary shaft.

[0005] This sieving device can stir the sieved powder paint to improve the sieving speed. However, it is found in actual use that the powder paint that fails to pass through the sieve will always stay on the filter screen. As time goes by, it will accumulate more and more, and finally it will affect the sieving of powder paint. It is also necessary to manually remove it to discharge the material, which is time-consuming and laborious. At the same time, when the filter screen is blocked after being used for a period of time, it also needs to be manually removed for cleaning, which is also time-consuming and laborious, reducing the sieving efficiency of powder paint. Therefore, improvements are proposed. Summary of the Utility Model
