[0036] Working principle: medicine bottles enter the feed star wheel 209 from the upstream equipment, and the feed star wheel 209 rotates to transport the medicine bottles to the feed star wheel 2 210. The feed star wheel 2 210 rotates to transport the medicine bottles to the circular conveyor mesh belt 4. There are five workstations on the circular conveyor mesh belt 4, which are the front weighing station, the filling station, the rear weighing station, the nitrogen filling station and the stoppering station. The circular conveyor mesh belt 4 is an intermittent working mode. It stops after transporting the medicine bottles to the designated position, and continues to run after completing the corresponding work. When the medicine bottle is transported on the circular conveyor belt 4, it first arrives at the front weighing station, and the bottle pushing plate 1 504 pushes the medicine bottle to the weighing bottle block 301. The weighing bottle block 301 is connected to a scale to weigh the medicine bottle. After weighing, the bottle pushing plate 2 505 pushes the medicine bottle back to the circular conveyor belt 4; then the circular conveyor belt 4 transports the medicine bottle to the filling station, and the filling needle rack 611 descends to fill the medicine bottle. After filling, the filling needle rack 611 rises. The medicine liquid in the filling needle rack 611 comes from the medicine liquid tank 15. The liquid in the liquid tank 15 is connected to the plunger pump 14, which is then connected to the filling needle rack 611. The plunger pump 14 is used to control the filling amount of the liquid medicine; the annular conveyor belt 4 then conveys the filled medicine bottles to the rear weighing station. The rear weighing station has a similar structure to the front weighing station. The medicine bottles are pushed to the weighing bottle block 301 by the bottle pushing plate to weigh the filled medicine bottles. The medicine bottles are weighed. The rear weighing station is provided with a refilling component 9, which can realize the left and right translation and lifting movement functions. The front end of the refilling component 9 has a refilling The needle rack 907 can be used to refill the medicine bottles with less filling volume after weighing. The refilling needle rack 907 first moves horizontally to the top of the medicine bottles with less filling volume, and then descends to the mouth of the medicine bottles for refilling. After the refilling is completed, the refilling needle rack 907 rises and finally moves horizontally to the origin. The medicine bottles are pushed back to the circular conveyor mesh belt 4 by the bottle pushing plate; then the circular conveyor mesh belt 4 conveys the medicine bottles to the nitrogen filling station, and the nitrogen filling needle rack descends to protect the medicine bottles with nitrogen. After the nitrogen filling is completed, the nitrogen filling needle rack rises; then the medicine bottles are conveyed to the stoppering station by the circular conveyor mesh belt 4 The rubber plug comes from the rubber plug pot 12, and reaches the plug connecting assembly 1101 from the rubber plug pot 12. The rubber plug is lifted up by the plugging assembly 1102 and put into the plug turning assembly 1103. The plug turning assembly 1103 flips the rubber plug over to the top of the plugging station, and the medicine bottle on the circular conveyor belt 4 is fixed by the medicine bottle fixing assembly 1108. The rubber plug is then pushed up to the plugging guide assembly 1106 by the plugging assembly 1105, and finally the plugging assembly 1105 and the plugging guide assembly 1106 are lowered into the medicine bottle together to plug the medicine bottle. After plugging, the annular conveyor belt 4 transports the medicine bottles to the discharge star wheel 1 1302, and the discharge star wheel 1 1302 then transports the medicine bottles to the discharge star wheel 2 1303. Due to the differences in the subsequent processes of the medicine bottles, the syringe bottles are transported from the discharge star wheel 2 1303 to the discharge star wheel 3 1304, and the discharge star wheel 3 1304 is connected to the downstream equipment. The pre-filled needles and cartridge bottles are transported from the discharge star wheel 2 1303 to the discharge star wheel 4 1305, and the discharge star wheel 4 1305 is connected to the downstream equipment.
