Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a coating fine grinding equipment. Background Art

[0002] Paint is a material that can be applied to the surface of an object to be protected or decorated and can form a firmly attached continuous film with the coated object. It is usually a viscous liquid prepared with organic solvents or water with resin, oil, emulsion, etc. as the main ingredients, with or without pigments and fillers, and by adding corresponding additives. Paint is not limited to liquid state, powder coating is also a large category of it.

[0003] Paint grinding is an important step in the paint production process. It aims to evenly mix different raw materials through mechanical grinding and achieve ideal viscosity, appearance and stability requirements. The paint grinding steps usually include initial grinding, re-grinding and final grinding. The purpose of this process is to reduce the particle size in the paint to improve the sedimentation stability of the paint, the uniformity of the film thickness, and the hardness, adhesion and wear resistance of the film.

[0004] The prior art patent document with publication number CN211537959U provides an environmentally friendly real stone paint fine grinding device, which is provided with a temperature-controlled grinding mechanism. The temperature-controlled grinding mechanism includes a power box, a grinding box and an air supply pipe, etc. The paint can be transported to the interior of the grinding box through the provided feed pipe and will not contact the air collecting box, the mounting plate and the fixed rod inside the temperature-controlled grinding mechanism. The moving plate and the stirring rod can be rotated by the coordinated use of the provided first motor and the transmission shaft. The wind generated by the fan will enter the interior of the air collecting box through the air supply pipe, and the air collecting box will evenly distribute the wind to the interior of the three groups of fixed plates. The air outlet can cool the paint during the paint grinding process to prevent the paint from being modified due to temperature changes.

[0005] In the above-mentioned prior art, although the grinding equipment in the patented technology is provided with a power box, a grinding box and an air duct to form a temperature-controlled grinding mechanism, the paint can be cooled during the grinding process to prevent the paint from being modified due to temperature changes, but the grinding equipment in the patented technology is not provided with a device for screening the ground paint, and it is impossible to filter out the incompletely ground particles. When the ground paint needs to be processed according to different requirements, it is impossible to conveniently screen and remove them, and it can only be screened separately, which greatly increases the workload and reduces the work efficiency. Therefore, we need a paint fine grinding equipment. Utility Model Content
