Description

Technical Field

[0001] The utility model relates to the technical field of powder coating production, in particular to a pretreatment device for powder coating production. Background Art

[0002] Powder coatings are synthetic resin coatings in a solid powder form, composed of solid resins, pigments, fillers, and additives. Unlike conventional solvent-based and water-based coatings, their dispersion medium is air, not solvent or water. The production of powder coatings requires a pre-treatment process in which the various solid and liquid raw materials are stirred and mixed.

[0003] Problems compared with the existing technology: In the existing technology, due to the pretreatment device used in powder coating production, it is not convenient to remove impurities mixed in it when pretreating the powder coating raw materials, which will cause large particles to exist in the mixed powder coating, reducing the processing quality of the powder coating. There is a screening device before stirring and mixing, but the efficiency of raw material screening is low, and it is not convenient to automatically clean the filtered material, which affects the screening effect of the raw materials and has poor practicality. For this reason, we propose a pretreatment device for powder coating production to solve the above problems. Utility Model Content
