Mixing device for acrylic resin-based powder paints

By designing an internal dispersing component and mixer, the problem of agglomeration in acrylic resin-based powder coatings during the mixing process was solved, achieving deep contact and uniform mixing between the powder and the solution, thereby improving the film-forming performance and stability of the coating.

AI Technical Summary

⚠Technical Problem

During the mixing process of acrylic resin-based powder coatings, the materials are prone to clumping, resulting in uneven mixing and affecting the film-forming properties and quality stability of the coating.

⚗Method used

A mixing device including an internal dispersing component and a mixer was designed. The internal dispersing component breaks up agglomerates and achieves deep dispensing and premixing of powder and solution by using the interlacing cutting and negative pressure effect of the cutting blades and the guide blades through the annular guide channel between the inner and outer cylinders. Combined with the convective mixing of the upper and lower bidirectional mixing blades, uniformity is ensured.

🎯Benefits of technology

It effectively breaks up powder lumps, improves mixing uniformity, enhances the application performance of the coating and the final coating quality, and avoids the occurrence of coating defects.

Abstract

The application discloses a mixing device for acrylic resin-based powder coating and relates to the technical field of mixers, which comprises a mixing box and a box cover. A driving shaft is rotatably installed on the lower surface of the box cover through a bearing. The upper end of the driving shaft extends to the upper side of the mixing box and is connected with a power assembly. A mixer is installed on the outer wall of the driving shaft. An outer cylinder is fixedly installed on the lower end of the outer wall of the box cover. An inner dispersing assembly for dispersing powder materials to avoid caking is arranged in the inner cylinder. The inner dispersing assembly is in driving connection with the driving shaft through a transmission assembly. The application has the beneficial effect that the annular distribution sheet of each group of cutting blades is alternately distributed with the sheet of the adjacent group, forming staggered cutting surfaces. When the cutting surfaces move, the powder coating in the annular flow channel between the outer cylinder and the inner cylinder is fully cut and dispersed, the caking of the powder in the storage and conveying process is directly broken, and the caked materials are prevented from entering the subsequent mixing link to affect the mixing uniformity.
