[0022] A rotating motor 18 is provided in the tablet pressing bin 31, the rotating main shaft 1 extends upward, and a tablet pressing slot plate 14 is correspondingly installed at the rod end, and a circle of evenly spaced pressing slots 21 is provided on the tablet pressing slot plate 14, and the pressing slot 21 is set as a slot body structure that is transparent from top to bottom, and the size of the pressing slot 21 is adapted to the size of the colistin sulfate tablets, and a fixed pad 13 is also provided on the right side of the lower end of the tablet pressing slot plate 14, and the fixed pad 13 blocks the pressing slot 21 at the right side of the tablet pressing slot plate 14, and the position of the upper discharge barrel 17 corresponds to the position of the blocked pressing slot 21 on the right side, so that the powder coming down from the discharge barrel 17 falls into the pressing slot 21 accordingly;

[0023] A pressing mechanism 16 is also installed on the partition 12. The pressing rod of the pressing mechanism 16 extends downward, and a pressing plate 15 is installed at the end of the rod. The size of the pressing plate 15 is adapted to the size of the pressing groove 21, and the position of the pressing plate 15 corresponds to the position of the blocked pressing groove 21 on the right side, so that the powder in the pressing groove 21 can be squeezed into sheets.

[0024] An air pump 5 is also provided above the left side of the tablet pressing groove plate 14 , and the air pump 5 is correspondingly mounted on the partition plate 12 , and the nozzle 6 of the air pump 5 is downwardly directed toward the unblocked pressing groove 21 on the left side of the tablet pressing groove plate 14 .

[0025] A screen plate 7 is also provided at the lower left side of the tabletting groove plate 14, and a funnel 8 is connected to the lower end of the screen plate 7, and a recovery box 10 is correspondingly provided below the funnel 8; the screen plate 7 is inclined, and the screen plate 7 is also connected to a discharge plate 9 in the inclined direction, and the discharge plate 9 is also inclined.

[0026] A feed port 19 is also provided at the upper end of the silo 3, and the lower end of the silo 3 is in the shape of a funnel 8; a material shifting rod 2 is also installed on the main shaft 1 of the unloading motor 11, and the material shifting rod 2 is evenly spaced up and down; the pressing grooves 21 on the tablet pressing groove plate 14 are arranged in a circle with even spacing, and a total of twenty are arranged.

[0027] The specific working process of this device is as follows: when in use, the powder is put into the silo through the feed port. First, the unloading motor rotates and then drives the material lever to rotate to avoid poor unloading of the powder. At this time, under the action of the spiral unloading blades, the powder is unloaded through the unloading barrel, and the powder just falls into the pressing groove of the tablet pressing groove plate. Then the rotating motor below rotates accordingly. The rotating motor can be set to a stepping transmission mode. After rotation, the pressing groove with the powder rotates to the bottom of the pressing plate. Since a fixed pad is provided at the lower right end of the tablet pressing groove plate, the powder in the pressing groove on the right will not leak and will rotate and move accordingly.

[0028] When the pressing groove with powder moves to the bottom of the pressing plate, the upper pressing mechanism is started, and the pressing plate presses the powder onto the fixed pad to achieve tableting. Then the tableting groove plate continues to rotate and move until it moves to the bottom of the jet head on the left. The air pump is turned on, and the jet head blows the tablets in the pressing groove onto the screen plate below. There will basically be a lot of powder left in the upper tableting groove plate and the pressing groove. After blowing, the tablets fall on the screen plate, and the excess powder falls from the screen plate into the funnel and enters the recycling box for recycling; the tablets fall onto the discharge plate along with the inclined screen plate and are discharged, completing the overall pressing process of colistin sulfate tablets.

[0029] The above-mentioned specific implementation mode is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
