[0002] Paint is a mixed material made after processing. Different raw materials need to be added for mixing during processing. In order to ensure the stability of processing and feeding, a feeding device is usually used to add materials. Existing paint processing feeding devices, such as a paint processing feeding device disclosed in application No. CN202321220722.9, can set a sieve plate and a feeding mechanism, so that the sieve plate can screen the added materials and dredge the sieve plate, thereby avoiding the sieve plate being blocked by larger materials when the feeding pipe is feeding, resulting in the inability to discharge materials.

[0003] However, in actual use, the reciprocating movement of the drum to clear the screen plate is inefficient and easily causes problems such as raw material blockage and abnormal feeding, which in turn affects the effect and production efficiency of the coating processing. In addition, the size of the raw material particles will directly affect the speed of coating mixing. In order to ensure the effect of the coating product, it is necessary to further ensure the fineness of the raw materials. The existing feeding device can only filter it, and the utilization rate of the raw materials is low. For this reason, we propose a coating processing feeding device to solve the above problems.
