Description

Technical Field

[0001] The utility model relates to the technical field of color mixing equipment, in particular to a color mixing equipment for water-based paint. Background Art

[0002] Traditionally, the color matching of paints and coatings is done by comparing them with color cards by the human eye. On the one hand, manual mixing will result in long-term contact with paints and coatings, which will cause damage to the health of workers; on the other hand, manual color matching will cause color difference and high waste of raw materials.

[0003] The prior art (CN219849404U) discloses a color mixing machine based on the production of water-based paint. The servo motor drives each group of paint buckets to rotate to achieve flexible position adjustment, thereby greatly improving the flexibility of material unloading. The electric push rod and the rotating drum allow the stirring blades to be freely inserted and pulled out of the bucket, which is convenient for stirring during color mixing and improves the color mixing efficiency. However, since the water-based paint raw materials need to be loaded one by one and the stirring process adopts an exposed processing method without a pre-mixing device, there may be problems such as low color mixing efficiency and contamination of the water-based paint during the mixing stage, which is not conducive to the efficient production and processing of water-based paint.

[0004] To this end, a color mixing device for water-based paint is proposed, which has the advantages of preventing paint pollution, automatic color mixing and rapid mixing and stirring of raw materials, thereby solving the problems in the above-mentioned background technology.
