Description

Technical Field

[0001] The present invention relates to the field of pharmaceutical production, and particularly to a filling device for veterinary drug production. Background Art

[0002] Veterinary drugs are substances that can improve the production performance of animals and have the functions of preventing, treating, and diagnosing diseases. Currently, during the production process of liquid veterinary drugs, a filling machine is required to fill the liquid medicine into the bottle body. During the filling process of the liquid medicine, as the liquid level in the bottle body rises, the liquid medicine is very likely to splash out of the bottle during filling. In the production process of veterinary drugs, since the amount of liquid medicine filled each time is certain, the splashed part of the liquid medicine easily causes the drug content to decrease, resulting in a decrease in the product qualification rate. Moreover, the liquid medicine splashes onto the surface of the equipment or even the cables, which is very likely to cause harm to the equipment and even the staff, reducing the safety of veterinary drug production.

[0003] Therefore, there is a filling machine for veterinary drug production that prevents splashing, such as the one with the patent number CN218088932U. However, this device has the following defects when in use. For example, according to its attached drawings, its conveying device is a conveyor belt. However, the conveyor belt is relatively soft, so it is very difficult to ensure that the medicine will not be skewed or shaken during the conveying and moving process of the medicine, resulting in the liquid medicine nozzle not being able to smoothly insert into the top opening of the medicine bottle. At the same time, when the diameter of the liquid medicine nozzle is larger than the inner diameter of the top opening of the medicine bottle, it is easy to insert, but the liquid medicine is easy to splash out through the gap between the side wall of the top opening of the medicine bottle and the outer wall of the liquid medicine nozzle. When the diameter of the liquid medicine nozzle is adapted to the inner diameter of the top opening of the medicine bottle, the liquid medicine is not easy to splash out through the gap between the side wall of the top opening of the medicine bottle and the outer wall of the liquid medicine nozzle, but it is not easy to insert, thus affecting the processing work.

The top of the measuring cylinder 10 is provided with an electromagnet II22 which is magnetically connected to the rim 21. The annular seat 20 and the inner top wall of the measuring cylinder 10 are also connected through an air bag layer 23. The air bag layer 23 is connected to a circle of purge pipes 25 below the sealing ring 14 through a corrugated hose II24. Gas nozzles 26 are evenly arranged on the side walls of the purge pipes 25, and the gas nozzles 26 are arranged obliquely upward toward the water absorption layer 15 and the sealing ring 14.

[0016] The water absorbing layer 15 and the sealing ring 14 are located just above the opening of the purge tube 25. The purge tube 25 is fixedly connected to the outer wall of the measuring cylinder 10 through a connecting tube. One end of the corrugated hose II24 is connected to the purge tube 25. The other end of the corrugated hose II24 is provided with a three-way pipe. The two groups of inlet ends of the three-way pipe are respectively connected to the air bag layer 23 and the vertical pipe 13 above the liquid outlet pipe 17. Preferably, it is connected to the inner top wall of the measuring cylinder 10 in the opening of the vertical pipe 13. A check valve is provided on the inlet end of the three-way pipe.

[0017] The annular seat 20 is arranged above the liquid inlet tube in the measuring cylinder 10, the diameter of the annular seat 20 is adapted to the size of the internal opening of the measuring cylinder 10, the inner diameter of the annular seat 20 is adapted to the diameter of the vertical tube 13, the number of the surrounding edges 21 is two groups, wherein the two groups of surrounding edges 21 are respectively arranged at the inner and outer sides of the top of the annular seat 20, the airbag layer 23 is arranged between the two groups of surrounding edges 21, and the inner top wall and the inner bottom wall of the airbag layer 23 are connected by an elastic rope 27.

[0018] The liquid outlet pipe 17 is located directly above the opening of one group of slots 9, the top of the liquid outlet pipe 17 is sealed, a one-way air inlet pipe 28 is provided on the top wall of the measuring cylinder 10 directly above the liquid outlet pipe 17, the size of the liquid outlet pipe 17 is adapted to the size of the internal opening of the vertical pipe 13, the bottom end of the liquid outlet pipe 17 is not lower than the horizontal plane of the bottom end of the vertical pipe 13, the length of the strip opening 19 is greater than the height of the liquid outlet 16, and the strip opening 19 and the liquid outlet 16 are correspondingly arranged.

[0019] In this embodiment, a liquid level sensor is disposed at the bottom of the measuring cylinder 10 , and a solenoid valve is disposed on the liquid inlet pipe on the side wall of the measuring cylinder 10 .

[0020] The working principle of the present invention is as follows: insert the medicine bottle into the card slot 9 of the metal seat 8, and the conveyor belt 2 drives the metal seat 8 and the medicine bottle to move, so that they are displaced one by one to the position directly below the filling mechanism 5. When the metal seat 8 drives the medicine bottle to be displaced to the position directly below the filling mechanism 5, the conveyor belt 2 stops working, and the electromagnet 17 works at this time and plays a magnetic fixing role on the metal seat 8 directly above it through the rubber conveyor belt 2, and also plays a supporting and fixing role to prevent the metal seat 8 from swinging under other influences, and the metal seat 8 fixes the medicine bottle through the card slot 9 to prevent it from swinging or tilting. Then the solenoid valve in the liquid inlet pipe on the measuring cylinder 10 is opened, and the medicine liquid in the liquid storage tank 4 enters the measuring cylinder 10 through the corrugated hose I12. When the liquid level sensor detects that the amount of medicine reaches the standard, the solenoid valve on the liquid inlet pipe is closed, and the hydraulic rod 11 drives the measuring cylinder 10 to move downward so that the vertical pipe 13 and the sealing ring 14 are tightly attached to the top of the medicine bottle. At the same time, the electric push rod 18 drives the liquid outlet pipe 17 to move downward to the top opening of the medicine bottle. When the liquid outlet pipe 17 moves downward and drives the strip opening 19 to move in the same direction, the strip opening 19 will be aligned with the liquid outlet 16 and connected. Finally, the top of the strip opening 19 is flush with the top of the liquid outlet 16. Then the medicine liquid in the measuring cylinder 10 is injected into the top of the medicine bottle through the liquid outlet 16, the strip opening 19 and the liquid outlet pipe 17. At this time, the liquid medicine in the medicine bottle will quickly cover the lower end of the liquid outlet pipe 17, so that the liquid medicine in the medicine bottle can buffer the liquid medicine sprayed out of the liquid outlet pipe 17 to prevent the liquid medicine from splashing out. At the same time, the vertical pipe 13 and the sealing ring 14 can further prevent the liquid medicine from splashing out through the top opening of the medicine bottle. Since the liquid outlet pipe 17 is small, it is convenient for it to be smoothly inserted into the medicine bottle for liquid injection. When the amount of liquid medicine in the medicine bottle gradually increases, the electric push rod 18 drives the liquid outlet pipe 17 to slowly move upward so that the liquid medicine continues to be injected into the medicine bottle. At this time, the liquid outlet 16 will never be blocked by the liquid outlet pipe 17, so that the liquid medicine in the measuring cylinder 10 can flow smoothly into the medicine bottle. When the bottom end of the strip opening 19 is flush with the bottom end of the liquid outlet 16, the liquid medicine in the measuring cylinder 10 has been completely introduced into the medicine bottle. In the above process, when the electric push rod 18 drives the liquid outlet pipe 17 to move downward, the external air will be sucked into the vertical pipe 13 above the liquid outlet pipe 17 through the one-way air inlet pipe 28, and at the same time, the air is injected into the air bag layer 23 to make it stretch, and the electromagnet II22 is powered off, so that the stretched air bag layer 23 can push the annular seat 20 to move downward in the measuring cylinder 10, and then squeeze the internal liquid to quickly enter the medicine bottle through the liquid outlet 16, the strip opening 19 and the liquid outlet pipe 17; During the injection process, if a small amount of liquid medicine may splash out, it will be absorbed by the water absorption layer 15 to prevent it from splashing onto the surface of equipment such as the conveyor belt 2 and causing harm to subsequent workers who come into contact with it. When the injection is completed, the electric push rod 18 drives the liquid outlet pipe 17 to move up and reset, which will squeeze the gas in the vertical pipe 13 above it, open the switch valve on one inlet end of the three-way pipe, and allow the gas to be injected into the purge pipe 25 through the three-way pipe and the corrugated hose II24 and sprayed out by the gas nozzle 26, thereby blowing the top side wall of the medicine bottle and the water absorption layer 15 with gas, so that they are quickly dehydrated and dried, and at the same time, the switch valve on the other inlet end of the three-way pipe is opened, and the gas in the air bag layer 23 is injected into the purge pipe 25 through the three-way pipe and the corrugated hose II24. The gas is sprayed out by the gas nozzle 26, and then the gas blows the top side wall of the medicine bottle and the water absorption layer 15, so that they are quickly dehydrated and dried, so as to recover the gas in the airbag layer 23. When the airbag layer 23 is vented, the elastic rope 27 contracts, and the magnetic attraction force generated by the operation of the electromagnet II22 acts on the surrounding edge 21, thereby driving the annular seat 20 to move upward and compress the airbag layer 23 for reset. Finally, the surrounding edge 21 is magnetically connected to the electromagnet II22. At this time, the quantitative medicine solution can continue to be injected into the measuring cylinder 10, the hydraulic rod 11 drives the measuring cylinder 10 to reset upward, the electromagnet I7 is powered off, and the conveyor belt 2 drives the metal seat 8 and the medicine bottle above it to continue to move, and the above steps are repeated at the same time to perform continuous filling.

[0021] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
