Description

Technical Field

[0001] The utility model belongs to the technical field of mixing devices, in particular to an automatic paint color matching and mixing device. Background Art

[0002] Paint is an organic chemical polymer material. The coating film formed is a polymer compound type. It is usually based on resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives. It is a viscous liquid prepared with organic solvents or water. When the paint is used, the material ratio will be determined according to different situations, so a stirring device is needed to mix the materials.

[0003] At present, paint proportioning generally involves pouring paints of various colors into a mixing device for stirring and mixing. However, the mixing device currently used has a relatively simple structure and generally adopts a single stirring shaft for stirring, which leads to the easy occurrence of stirring dead corners in the mixing box. In addition, some paint particles are deposited at the bottom of the mixing device and are difficult to be effectively stirred, resulting in poor mixing effect. Utility Model Content
