Description

Technical Field

[0001] The utility model relates to the technical field of powder feeding, in particular to a powder feeding and leveling device. Background Art

[0002] Powder coating is completely different from general coating. It exists in the state of fine powder. Since no solvent is used, it is called powder coating. When using powder coating, the solvent pollution index is zero. Overspray of powder coating and coating of end coating can minimize the degree of environmental pollution and save resources and production costs.

[0003] The powder coating before tableting may have the problem of moisture and agglomeration, resulting in insufficient flatness of the fed powder. In addition, the powder coating needs to be placed inside the tableting mold before tableting. However, the powder accumulates during unloading and easily overflows to the outside of the molding mold, affecting the flatness of the subsequent powder. Therefore, a flattening device is needed to improve its flatness to ensure the quality of tableting.

[0004] However, when simply flattening the powder, due to the insufficient compactness of the powder, if it is slightly shaken by external influences during the feeding process, it is easy to cause the powder to become uneven again, and excess powder is easy to slide to the outside along with the feeding mechanism.

[0005] Therefore, those skilled in the art provide a powder feeding and leveling device to solve the problems raised in the above background technology. Utility Model Content
