The push rod 202 can completely overlap when it returns to the fixed frame 201.

[0031] The tablet pressing device is composed of a lower punch 301, a middle die 302, an upper punch 303, a cooling column 304, and a fixed platform 305. The lower punch 301, the cooling column 304, and the fixed platform 305 are fixed on the bottom surface of the base 1; the lower punch 301 can move in the vertical direction, and the moving distance of the lower punch 301 is slightly less than the thickness of the middle die 302; when the lower punch 301 moves to the highest point, the height is consistent with the cooling column 304; the fixed platform 305 can move in the vertical direction, the fixed platform 305 can rotate along its own axis, the moving distance of the fixed platform 305 is slightly greater than the thickness of the middle die 302, and the height of the fixed platform is consistent with the cooling column 304 when the fixed platform 305 is at the lowest point. The lower punch 301 and the cooling column 304 are installed at a fixed distance around the center of the fixed platform 305, and there are three lower punches 301, two cooling columns 304 are fixedly spaced between each lower punch 301, and the distance between the cooling columns 304 is equal to the distance between the lower punch 301 and the cooling column 304. The diameters of the lower punch 301 and the cooling column 304 are equal.

[0032] The middle die 302 is arranged on a fixed platform 305, wherein four fixed grooves are arranged at the center of the middle die 302, and a protrusion corresponding to the fixed groove of the middle die 302 is arranged at the top of the fixed platform 305, and the height of the protrusion is the height of the middle die 302. The middle die 302 is provided with 9 punching holes of the same diameter as the lower punch 301, and the positions of the punching holes correspond to the positions between the lower punch 301 and the cooling column 304.

[0033] The upper punch 303 is arranged below the top surface of the base 1. The diameter of the upper punch 303 is the same as that of the lower punch 301; the axis of the upper punch 30 is colinear with the axis of the lower punch 301. The upper punch 303 can move in the vertical direction. The upper punch 303 can extend into the punching hole of the middle die 302. A motor and a pressure sensor are arranged inside the upper punch 303 and the lower punch 301. The motor can provide a certain pressure for the tableting operation and transmit the pressure to the pressure sensor.

[0034] The filling device 4 is arranged below the top surface of the base 1 near any side surface, and the filling device 4 is composed of a filling machine 402 and a filling tube 401. One side of the filling tube 401 is connected to the filling machine 402, and the other side of the filling tube 401 is connected to the upper punch 303. The filling machine 402 can transport the medicine powder along the filling tube 401 to the upper punch 303. The upper punch 303 can transport the medicine powder inside the filling tube 401 to the groove formed by the punching hole of the lower punch 301 and the middle die 302.

[0035] When the probiotic tablets are tableted by a rotary tableting device, the lower punch 301 and the upper punch 303 can simultaneously provide pressure for the tableting device, thereby reducing the imbalance of upper and lower pressures on the probiotic tablets during tableting, which results in the low quality of the finished probiotic tablets.

[0036] The working principle of the rotary tablet pressing device for probiotic tablets:

[0037] 1. Clean the device. Install the cleaning device 2 in the groove inside the base 1, and install the middle mold 302 above the fixed platform 305. The inside of the filler 402 is provided with the probiotic powder to be tableted. The collection basket is installed in front of the fixed platform.

[0038] 2. Start the controller of the probiotic tablet rotary tablet pressing device.

[0039] 3. The push rod 202 is installed on the fixing frame 201 , and the push rod 202 is retracted into the fixing frame 201 .

[0040] 4. The lower punch 301 descends a certain distance. The upper punch 303 moves to the top of the middle die 302. The filling device 4 is started, and the powder in the filling machine 402 is transported to the upper punch 303 along the filling pipe 401. The upper punch 303 controls a certain amount of powder to fall into the inner side of the groove formed by the punching holes of the lower punch 301 and the middle die 302.

[0041] 5. The lower punch 301 moves upward, and the upper punch 303 moves downward. The powder is pressed into tablets in the punching hole by the pressure between the lower punch 301 and the upper punch 303. The pressure sensor collects the pressure data and transmits it to the controller. The lower punch 301 and the upper punch 303 maintain the set pressure for a period of time.

[0042] 6. Then the upper punch 303 returns to the upper side, and the lower punch 301 rises to the highest point to eject the probiotic tablet from the punch hole.

[0043] 7. The fixed frame 201 controls the push rod 202 to push the compressed probiotic tablets into the collection basket. When the push rod returns to the fixed frame 201, the powder absorber is activated, and the powder absorber can absorb the floating powder on the fixed table 305 and the inner side of the tablet pressing device.

[0044] 8. The fixed platform 305 lifts the middle die 302 upward for a distance. The middle die 302 is disconnected from the lower punch 301 and the cooling column 304 and rotates a certain angle, so that the next punching hole rotates to the upper side of the lower punch 301 and the fixed platform 305 returns to the initial height. Repeat the tableting process.

[0045] The filling device 4 and the cleaning device 2 can realize automatic filling of the device, and after tableting is completed, the cleaning device 2 can push the pressed probiotic tablets into the collection basket, realizing the functions of continuous automatic filling, automatic tableting, and automatic collection of the device.

[0046] During continuous tableting, the drug powder generates a certain pressure on the middle die 302, the lower punch 301, and the upper punch 303, and the pressure is converted into heat and accumulated in the punching hole of the middle die. The middle die 302 of the tableting device can rotate, so that the residual heat of the middle die 302 at the tableting location is cooled by the cooling column 304, and then punched again after cooling. And after rotation, the punching hole located in the cooling column rotates to between the upper punch and the lower punch for punching. The heat accumulated at the punching location during punching can be lost, and the heat generated by the continuous tableting of the device will not be conducted to the drug powder, causing the probiotics to be inactivated.

[0047] A powder absorber is provided in the cleaning device 2. During the tableting filling, tableting completion, and material pushing steps, some of the drug powder will diffuse into the device. When the accumulated drug powder increases, the tableting effect will be poor and the quality of the probiotic tablets will be reduced. After the diffused drug powder is absorbed by the powder absorber, the quality of the produced product can be guaranteed to meet the standards.
