Description

Technical Field

[0001] The present application relates to the technical field of grinders, and in particular to a powder coating grinder. Background Art

[0002] Powder coating is completely different from general coating. It exists in the form of fine powder. Because it does not use solvent, it is called powder coating. The main characteristics of powder coating are: harmless, high efficiency, resource saving and environmental protection. It has two categories: powder coating and powder coating. Powder coating is generally made of special resin, pigment, filler, curing agent and other additives, mixed in a certain proportion, and then prepared by hot extrusion and crushing and screening. Among them, crushing and screening is a more important link. Whether the particles of the coating components are uniform and fine will directly affect the performance of the finished product.

[0003] The patent document with the published announcement number CN212189329U provides a powder coating grinder. The utility model device screens the crushed material according to production needs through the material receiving trough, plug, spring, connecting rod and cylinder. The connecting rod is driven by the cylinder on the left to slide the plug back and forth through the slide. Conversely, the material at the bottom of the material receiving trough is pushed toward the direction of the second material distribution trough for discharge, and the material is screened through the second material distribution net, which is convenient for the production of fine powder, meets the needs of mass consumers, and increases the use function of the device.
