Synchronous powder feeding device for double-powder embedded type pressed parts

Abstract

A synchronous powder feeding device for double-powder embedded type pressed parts comprises an outer layer, a middle layer and an inner layer; a first feeding cavity with the upper portion and lower portion being open is defined between the outer layer and the middle layer; and a second feeding cavity with the upper portion and lower portion being open is defined between the middle layer and the inner layer. With the synchronous powder feeding device, embedded type tablets can be obtained through pressing, and the defect that existing pressing equipment cannot obtain double-powder embedded type pressed parts is overcome. Two different powders can be synchronously added into a die cavity at the same time, mixing of the different powders is eradicated in the feeding process, the embedded type tablets with the same density can be formed through pressing, the structure is simple, powder adding is convenient and rapid, and the defects that an existing feeding device cannot feed two materials synchronously without mixing the powders are overcome.

Description

Technical field: [0001] The invention relates to the field of double-powder preparation equipment, in particular to a powder feeding device of double-powder mosaic pressing molding equipment. Background technique: [0002] At present, tablets are becoming more and more common, and the fields where tablets are used are expanding, and the market demand for tablets is increasing year by year. Tablets are made by pressing powder or granules through high-pressure molding with a tablet press. The existing tablet press machine can press granular and powdery raw materials into tablets of various shapes, the molds are easy to replace and install, and the operation is simple and easy to learn. However, the existing pressing equipment can only press out tablets of one material or tablets mixed with multiple materials, and cannot produce mosaic pressed parts of multiple materials. With the continuous development of science, people's requirements for tablets continue to increase. Some ...

AI Technical Summary

Problems solved by technology

After a long period of research, the applicant invented a dual-powder mosaic-type synchronous powder feeding device for pressed parts, which can synchronously add different materials into the material chamber of the pressing equipment, and ensure that different materials will not mix with each other when they are added, so that Compressing mosaic tablets solves the problem that the existing technology cannot simultaneously add two materials without mixing to the compression equipment
