[0001] The utility model relates to the technical field of conveying systems, in particular to a conveying system for bottled liquid medicine. Background Art

[0002] The bottled liquid medicine delivery system is a complex mechanical and electronic system involving the coordinated work of multiple components and links.

[0003] Existing systems for bottled liquid medicine delivery have poor adaptability to liquid characteristics. Different liquid medicines have different physical and chemical properties, such as viscosity, density, surface tension, etc. These properties will affect the flow performance of the liquid medicine in the pipeline, and different flow rates need to be adjusted to control the accuracy of the liquid medicine. Although modern filling systems use flow rate control mechanisms, the filling device of the bottled liquid medicine delivery system has a complex structure, is difficult to disassemble and maintain, and is difficult to operate. In some cases, the bottled liquid medicine delivery system may lack effective emergency measures to deal with emergencies. For example, when a system fails, it may not be able to shut down or switch to a backup system in time; when liquid medicine leaks, it may not be able to promptly alarm or take other remedial measures.

[0010] Further, the valve stem is fixedly sleeved with a liquid blocking plug, and the liquid blocking plug is closely attached to the upper end of the valve plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. When it is necessary to transport bottled drugs, the liquid to be filled is stored in the filling box. When the system is started, the liquid flows through the liquid outlet pipe to the regulating valve. The regulating valve controls the flow rate and velocity of the liquid through its internal mechanism. The driving motor drives the worm to rotate, and the rotation of the worm simultaneously drives the connected worm gear to move back and forth in the worm rack. This movement is converted into the rotational and lifting movements of the valve stem through a series of gear transmissions. The lifting of the valve stem drives the opening and closing of the valve plate, thereby controlling the flow rate of the liquid passing through the valve port. At the same time, the liquid blocking plug is closely attached above the valve plate to ensure effective blocking of the liquid medicine in the non-opening state.

[0013] 2. After adjusting the flow rate, the liquid flows accurately from the regulating valve to the containers on the conveying track. The conveying track is driven by a track motor, which transports the empty containers from the input track to the filling position and continues to move forward to the capping machine. To ensure the filling accuracy, the electric telescopic pipe beside the conveying track drives the limiting push plate to move forward to gently push the containers to the precise position, preventing the containers from moving or tilting during the filling process.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , a technical solution is provided for a conveying system for bottled liquid medicine of the present invention, including a filling box 1, an input track 5, and an output track 8. One side of the filling box 1 is fixedly connected with a liquid outlet pipe 2. A regulating valve is fixedly arranged below the liquid outlet pipe 2. The lower end of the regulating valve is connected to a connecting hopper 3. A perfusion pipe 4 is fixedly arranged at the lower end of the connecting hopper 3. A conveying track 7 is arranged below the perfusion pipe 4. One end of the conveying track 7 is fixedly close to and placed on the input track 5, and the other end is fixedly close to and placed on a capping machine 10. The output track 8 is continuously placed after the capping machine 10. Baffles 9 are fixedly installed on one side of the input track 5, the conveying track 7, and the output track 8. And a track motor is installed outside the baffle 9. The central part inside the baffle beside the conveying track 7 is provided with an electric telescopic pipe, and the electric telescopic pipe is fixedly connected to a limiting push plate 6.

[0021] The regulating valve includes a linkage sprocket 15. One end of the linkage sprocket 15 is fixedly connected to a valve rod 25. The valve rod 25 is integrally formed with a valve plate 13. The valve rod 25 can drive the valve plate 13 to rotate and rise. A liquid blocking plug 12 is fixedly sleeved on the valve rod 25 and closely adheres to the upper end of the valve plate 13 to block the flow of liquid medicine to the gate opening. The lower end of the threaded shaft 26 is fixedly connected to a valve cover 24. The lower end of the valve cover 24 is fixedly connected to a valve body 23. The valve rod 25 is fixedly sleeved with a stuffing gland 11, and the stuffing gland 11 seals the outlet of the valve cover 24.

[0022] A driving assembly is fixedly installed on one side of the filling box 1 near the regulating valve. The driving assembly includes a chain 16

[0023] One end of the chain 16 is drivingly connected to a driving sprocket 14. The driving sprocket 14 is fixedly installed with a worm 17. The rear end of the worm 17 is rotatably connected to a driving motor 18. When the driving motor 18 is started, the driving motor 18 drives the worm 17 to rotate, and the worm 17 drives the driving sprocket 14 at the end to rotate.

[0024] The worm 17 rotates to drive the meshing worm wheel 19 to rotate. The other side of the worm wheel 19 meshes with the worm rack 20. The worm rack 20 moves forward or backward following the rotation of the worm wheel 19. The worm rack is fixedly connected to the surface of the sliding plate 22. The sliding plate 22 movably passes through two support plates 21. The two support plates 21 are fixedly installed on the surface of the filling box 1. The worm rack 20 drives the sliding plate 22 to move forward or backward on the two support plates 21. Thus, the driving sprocket 14 connected to the sliding plate by the worm 17 moves forward or backward.

[0025] The other end of the chain 16 is rotatably connected to three linkage sprockets 15. The three linkage sprockets 15 can reciprocate back and forth within the tracks of their respective threaded shafts 26. The fixing button 27 is fixed to the top of the threaded shaft 26 to prevent the linkage sprockets 15 from disengaging from the threaded shaft 26. While the driving sprocket 14 drives the three linkage sprockets 15 to rotate, it also reciprocates back and forth. Since the threaded shaft is fixed to the valve cover, the three linkage sprockets 15 can rotate and reciprocate back and forth on the threaded shaft. The linkage sprockets are fixedly connected to the valve stem 25. Thus, the three linkage sprockets 15 drive the fixedly connected valve stem 25 to rotate and lift, controlling the liquid outlet speed of the valve port.

[0026] Working principle: When it is necessary to transport bottled drugs, the filling box 1 stores the liquid to be filled. At this time, the system is started, and the liquid flows through the liquid outlet pipe 2 to the regulating valve. The regulating valve controls the flow rate and velocity of the liquid through its internal mechanism: The driving motor 18 drives the worm 17 to rotate. The rotation of the worm 17 simultaneously drives the meshing rotation of the driving sprocket 14 connected thereto, driving the rotation of the valve stem 25. The rotation of the valve stem 25 drives the rotation of the valve plate 13, thereby controlling the flow rate of the liquid through the valve port. At the same time, the liquid blocking plug 12 closely adheres above the valve plate 13 to ensure effective blocking of the liquid medicine in the non-opening state.

[0027] When the driving motor 18 is started, the worm wheel 19 meshing with the worm 17 rotates. The worm wheel 19 can drive the worm rack 20 to reciprocate back and forth. At this time, the driving sprocket rotates and reciprocates back and forth at the same time. This movement is transmitted to the linkage sprocket through the chain. The valve stem connected to the linkage sprocket also rotates and reciprocates back and forth at the same time. The valve stem realizes lifting, avoiding the problems that the liquid medicine always flushes the valve plate, resulting in drug property penetration and difficult cleaning of sediments.

[0028] After adjusting the flow rate, the liquid accurately flows from the regulating valve through the perfusion pipe 4 to the containers on the conveying track 7.

[0029] The conveying track 7 is driven by a track motor, which conveys the empty containers from the input track 5 to the perfusion position and continues to move forward to the capping machine 10. To ensure the filling accuracy, the electric telescopic pipe beside the conveying track 7 drives the limiting push plate 6 to move forward, so as to gently push the containers to the accurate position and prevent the containers from moving or tilting during the filling process.

[0030] The filled containers continue to move along the conveyor track 7 to the capping machine 10, and the capping machine 10 automatically caps and seals the containers. The capped containers are finally sent out of the system by the output track 8, ready for the next process or packaging.

[0031] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that, without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
