[0003] The filling work is a very strict and precise task, which needs to be completed in a clean room or dust-free workshop. The specific work process is as follows: Container inspection: Before filling, the containers need to be inspected to ensure their sealing performance and integrity. At the same time, it is also necessary to check whether the surface of the container is unclean or damaged. Confirmation of drug properties: For different types of drugs, their properties, dosage forms, etc. need to be confirmed, and operations need to be carried out strictly in accordance with the requirements. Filling process: The drug is sent to the filling production device through a specific pipeline, and then the filling production device quantitatively injects the drug into the containers that have been inspected and are in good condition. Packaging: After filling, the containers are sent to the inspection and packaging department for packaging, and finally inspected before being put on the market.

[0024] As Figures 1 to 7 shown, a medicine filling production device includes a base 1, a medicine storage container 3, a delivery pump and a filling gun 19. The delivery pump is provided with a medicine inlet pipe 11 and a medicine outlet pipe 12. The medicine inlet pipe 11 is communicated with the medicine storage container 3. A filling valve is arranged on the medicine outlet pipe 12. The filling gun 19 is communicated with the delivery pump through the medicine outlet pipe 12. A drive part 2 is arranged on the base 1. The drive part 2 is preferably a motor. A drive rod 5 is arranged at the output end of the drive part 2. A drive pin 6 is eccentrically arranged on the drive rod 5. A disc 7 is rotatably connected to the base 1. A plurality of drive holes 8 for driving the filling container to rotate are annularly arranged on the disc 7. A driven wheel 9 is coaxially arranged with the disc 7. A plurality of driven grooves 10 adapted to the drive pins 6 are annularly arranged on the edge of the driven wheel 9. Among the rotation gaps of the driven wheel 9, one of the drive holes 8 on the disc 7 corresponds to the filling gun 19.

[0025] During actual use, place the filling container in the driving hole 8. The driving part 2 drives the driving pin 6 on the driving rod 5 to rotate. The driving pin 6 drives the driven wheel 9 to rotate intermittently through the driven groove 10. The driven wheel 9 drives the disc 7 to rotate intermittently. The disc 7 drives the filling container to rotate intermittently through the driving hole 8 for station conversion. During the rotation interval, the filling valve is opened. The transfer pump sucks the medicine from the medicine storage container 3 through the medicine inlet pipe 11 and transports the medicine to the filling gun 19 through the medicine outlet pipe 12, and fills the filling container through the filling gun 19. By adopting a pure mechanical transmission method, the influence of electronic components and environmental factors is reduced. The positioning accuracy of the filling container is high, which is beneficial to improving the performance and stability of the entire medicine filling production equipment, and the reliability is high.

[0026] To achieve the purpose of improving the performance and stability of the medicine filling production equipment, preferably, a locking arc 4 is coaxially arranged on the driving rod 5, and a plurality of locking grooves 13 adapted to the locking arc 4 are annularly arranged on the driven wheel 9. Each time the driven wheel 9 rotates once, the locking arc 4 is inserted into the locking groove 13 once, preventing the driven wheel 9 from generating inertial rotation during the rotation interval, which is beneficial to improving the high positioning accuracy of the filling container, and further improving the performance and stability of the entire medicine filling production equipment.

[0027] To achieve the purpose of improving the performance and stability of the medicine filling production equipment, preferably, the filling valve includes a valve cavity 14, a valve core 15, a connecting rod 16, a tension spring 17 and a cam 18. The valve cavity 14 is horizontally arranged on the medicine outlet pipe 12. The valve core 15 is slidably connected inside the valve cavity 14. A connecting rod 16 passing through the valve cavity 14 is arranged on the valve core 15. A tension spring 17 is arranged between the side wall of the valve cavity 14 and the valve core 15. The output end of the driving part 2 is provided with a cam 18. The connecting rod 16 is in close contact with the cam surface of the cam 18 under the pulling force of the tension spring 17. During the operation of the driving part 2, the cam 18 is driven to rotate synchronously. The cam 18 drives the valve core 15 to slide back and forth in the valve cavity 14 through the connecting rod 16. During the rotation of the disc 7, the medicine outlet pipe 12 is closed, and during the rotation interval of the disc 7, the medicine outlet pipe 12 is opened. The medicine flows from the medicine outlet pipe 12 to the filling gun 19 and is filled into the filling container through the filling gun 19. By adopting a pure mechanical transmission method, the influence of electronic components and environmental factors is reduced. The positioning accuracy of the filling container is high, which is beneficial to improving the performance and stability of the entire medicine filling production equipment, and the reliability is high.

[0028] Preferably, a first roller is rotatably connected to the end of the connecting rod 16 in contact with the cam surface of the cam 18. Through the arrangement of the first roller, the sliding friction between the connecting rod 16 and the cam 18 is changed into the rolling friction between the first roller and the cam 18, which is beneficial to reducing the friction force, reducing the noise and prolonging the service life of the equipment.

[0029] For the purpose of improving the performance and stability of pharmaceutical filling production equipment, preferably, the filling gun 19 is vertically slidably connected to the medicine outlet pipe 12. The output end of the driving part 2 is provided with a driving belt 21. At the upper edge of the base 1, there is a support plate 20. On the support plate 20, a driven pulley 22 and a columnar cam 24 arranged coaxially are rotatably connected. A belt 23 is connected between the driving belt 21 and the driven pulley 22 for transmission. The support plate 20 is provided with a guiding groove 25. Inside the guiding groove 25, a horizontal rod 26 is vertically slidably connected. Between the horizontal rod 26 and the inner top wall of the guiding groove 25, an elastic member 27 is provided. One end of the horizontal rod 26 is fixedly connected to the filling gun 19, and the other end of the horizontal rod 26 is in close contact with the cam surface of the columnar cam 24 under the elastic force of the elastic member 27. The elastic member 27 is preferably a spring or an elastic sheet. During the operation of the driving part 2, it drives the driving belt 21 to rotate. The driving belt 21 drives the driven pulley 22 to rotate through the belt 23, and the driven pulley 22 drives the columnar cam 24 to rotate synchronously. Under the lifting action of the columnar cam 24 and the elastic force of the elastic member 27, the horizontal rod 26 drives the filling gun 19 to perform intermittent lifting and lowering movements. During the filling process, the filling gun 19 moves downward close to the filling container. After the filling is completed, the filling gun 19 rises away from the filling container. By adopting a pure mechanical transmission method, the influence of electronic components and environmental factors is reduced, the positioning accuracy of the filling container is high, which is beneficial to improving the performance and stability of the entire pharmaceutical filling production equipment, and the reliability is high.

[0030] For the purpose of further improving the performance and stability of the pharmaceutical filling production equipment, preferably, a large gear 28 is provided at the lower end of the columnar cam 24. On the support plate 20, a bushing 30 is rotatably connected. Inside the bushing 30, a spline groove 31 is provided. On the outer surface of the bushing 30, a small gear 29 meshing with the large gear 28 is provided. On the horizontal rod 26, a bearing seat 32 is provided. On the bearing seat 32, a rotating shaft 33 is rotatably connected. On the rotating shaft 33, a spline 34 adapted to the spline groove 31 is provided. At the lower end of the rotating shaft 33, a sleeve 35 is provided. When the columnar cam 24 rotates, it will drive the large gear 28 to rotate synchronously. The large gear 28 drives the small gear 29 to rotate at a high speed, and the small gear 29 drives the bushing 30 to rotate at a high speed. Since the horizontal rod 26 will drive the rotating shaft 33 to lift and lower synchronously during the lifting and lowering process, and the bushing 30 can drive the rotating shaft 33 to rotate synchronously through the spline groove 31 and the spline 34, therefore, the rotating shaft 33 will perform a combined movement of lifting and rotation. During the gap of station conversion, the sealing cap of the filling container can be placed on the opening of the filling container, and the sleeve 35 will automatically tighten the sealing cap during the descending process.

[0031] Preferably, a second roller is rotatably connected to one end of the horizontal rod 26 that contacts the cam surface of the columnar cam 24. Through the arrangement of the second roller, the sliding friction between the horizontal rod 26 and the columnar cam 24 is converted into the rolling friction between the second roller and the columnar cam 24, which is beneficial to reducing the friction force, reducing the noise, and extending the service life of the equipment.

[0032] In order to achieve the purpose of preventing the transfer pump from causing drug contamination, preferably, the transfer pump includes a pump housing 36, a hose 37, and a rotor 38. The pump housing 6 is arranged inside the base 1. The hose 37 is arranged on the inner wall of the pump housing 36. The output end of the driving part 2 penetrates through the pump housing 36, and the output end of the driving part 2 is provided with a rotor 38 located inside the pump housing 36. The medicine inlet pipe 11 and the medicine outlet pipe 12 are respectively communicated with both ends of the hose 37. During the operation of the driving part 2, the rotor 38 is driven to rotate synchronously, intermittently squeezing the hose 37 to generate negative pressure inside the hose 37, sucking and conveying the medicine. The medicine only flows inside the hose 37 and does not contact other parts of the transfer pump, which is beneficial to preventing the transfer pump from being contaminated.

[0033] Compared with the prior art, through the cooperation of the base 1, the medicine storage container 3, the transfer pump, the filling gun 19, the medicine inlet pipe 11, the medicine outlet pipe 12, the filling valve, the driving part 2, the driving rod 5, the driving pin 6, the disc 7, the filling container, the driving hole 8, the driven wheel 9, and the driven groove 10 in the present invention, when filling the medicine, the filling container is placed in the driving hole 8. The driving part 2 drives the driving pin 6 on the driving rod 5 to rotate. The driving pin 6 drives the driven wheel 9 to rotate intermittently through the driven groove 10. The driven wheel 9 drives the disc 7 to rotate intermittently. The disc 7 drives the filling container to rotate intermittently through the driving hole 8 for station conversion. During the rotation interval, the filling valve is opened. The transfer pump sucks the medicine from the medicine storage container 3 through the medicine inlet pipe 11 and conveys the medicine to the filling gun 19 through the medicine outlet pipe 12, and fills the medicine into the filling container through the filling gun 19. By adopting a pure mechanical transmission method, the influence of electronic components and environmental factors is reduced, the positioning accuracy of the filling container is high, which is beneficial to improving the performance and stability of the entire medicine filling production equipment, and the reliability is high.
