[0002] Paint is a common decoration material, which is widely used in home decoration, construction, industry and other fields. In the production and processing of paint, it is necessary to first transfer the powdery paint raw materials to the mixing kettle through the feeding structure, and the paint is mixed and prepared in the mixing kettle.
[0003] During the addition of the powdery paint raw materials, since most of them are directly added into the interior of the mixing kettle, it is easy for the paint raw materials to agglomerate during production and mixing, the required mixing time is longer, and the mixing effect is poor. Even raw material supplementation is required, which is a waste of resources. In addition, when using the tube conveying method to gradually add the powdery raw materials, since there may be residues of the paint raw materials in the conveying pipe, it is not convenient to calculate and count the dosage of the powdery paint raw materials added, which may lead to the situation of adding too much or too little, and thus more time is required for adjustment. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is that when adding the existing powdery paint raw materials, they are added by direct addition or tube conveying methods. The former is easy to agglomerate during mixing, affecting the production time of the paint and wasting resources, and the latter cannot calculate and adjust the specific amount of powdery raw materials added.
[0005] To solve the above technical problems, the technical solution provided by the utility model is a feeding device for environmentally friendly paint processing, including a feeding hopper.
