When the push rod motor drives the upper die to move up and down, the upper die can be kept stable, and the tablet pressing quality of the pharmaceutical tablet press is improved. The utility model also has the advantages of simple and compact structure, low manufacturing cost and easy use.

[0004] According to the related technology in the above, the inventor finds that when the tablet press is used for pharmaceutical purposes, the upper die and the lower die are used to extrude the medicine powder to form tablets, and after the upper die and the lower die are opened, the tablets are stored in the die cavity of the lower die. In the later stage, the tablets need to be lifted one by one and taken out, and the process of taking medicine is complicated and has many steps. This results in that the continuous extrusion operation of the medicine powder cannot be performed when the medicine is taken, and the continuous preparation efficiency of the tablets is affected. Utility model content

[0005] In order to overcome the situation that the existing upper die and lower die are used to extrude the medicine powder to form tablets, and after the upper die and the lower die are opened, the tablets are stored in the die cavity of the lower die, and in the later stage, the tablets need to be lifted one by one and taken out, and the process of taking medicine is complicated and has many steps, which results in that the continuous extrusion operation of the medicine powder cannot be performed when the medicine is taken, and the continuous preparation efficiency of the tablets is affected, the application provides a high-efficiency tablet press for tablet preparation.
