The negative pressure collecting mechanism collects the tablets ejected from the pressing groove of the powder tray 11 by means of negative pressure suction. The collected tablets fall into a collecting vertical cylinder 19. After a certain amount is collected, the end of the collecting vertical cylinder 19 can be opened to temporarily store the tablets in a collecting groove 20 for subsequent processing operations, thereby realizing automatic collection, reducing workload, and eliminating safety hazards. The overall practicality is high.

[0031] The front of the machine 1 is provided with an operating table 2, the machine 1 includes a table top and a bracket below, and a frame structure is also provided above the machine 1 to facilitate the installation of other mechanisms or components of the tablet press. A driving motor 3 is provided at the bottom of the machine 1, and the driving motor 3 drives the lower pressing plate 5, the upper pressing plate 7 and the powder plate 11 to rotate through the transmission component 4. Figure 2 and Figure 4The transmission assembly 4 includes a driving wheel, a connecting belt, a driven wheel, etc. The driving wheel is connected to the output end of the driving motor 3, and a rotating shaft is installed upwardly from the axis of the driven wheel. The lower pressure plate 5, the upper pressure plate 7 and the powder plate 11 are installed on the rotating shaft, and the powder plate 11 is located between the lower pressure plate 5 and the upper pressure plate 7.

[0032] A lower pressing assembly 6 is provided on the lower pressing plate 5, and an upper pressing assembly 8 is provided on the upper pressing plate 7. The lower pressing assembly 6 and the upper pressing assembly 8 are aligned in upper and lower positions and are equal in number. When the lower pressing assembly 6 and the upper pressing assembly 8 move toward each other, the powder in the pressing groove of the powder disk 11 can be tableted.

[0033] Both ends of the lower pressing component 6 and the upper pressing component 8 are provided with a roller part 9 and a punch part 10, the roller part 9 and the punch part 10 are respectively located at the two ends, and the punch part 10 is used for tableting of medicine powder.

[0034] The fixed circular wheel 13 is mounted on the table 1 through a frame, and combined with Figure 1 and Figure 4 During the rotation of the upper pressing plate 7, the roller part 9 at the top of the upper pressing assembly 8 contacts and abuts against the circumferential wall of the fixed circular wheel 13, causing the upper pressing assembly 8 to be pressed downward as a whole, and the punch part 10 enters the pressing groove in the powder disk 11 to perform tableting.

[0035] The tablet pressing block 14 is located on the table 1 below the fixed circular wheel 13, and is combined with Figure 2 and Figure 4 After the roller part 9 at the bottom of the lower pressing component 6 contacts the tablet pressing block 14, it can also drive the lower pressing component 6 to rise, and the punch part 10 at the top of the lower pressing component 6 moves up to press the tablet together with the upper pressing component 8.
