[0001] This utility model relates to the field of traditional Chinese veterinary medicine filling technology, specifically, to a foam-free liquid filling head for concentrated traditional Chinese veterinary medicine. Background Technology

[0002] Traditional Chinese veterinary medicine is a drug system that applies the theories of traditional Chinese medicine to the prevention, treatment and health care of animal diseases. Its core lies in using natural drugs and their extracts to regulate the physiological functions of the animal body in order to prevent and treat diseases and promote health.

[0003] For liquid veterinary medicines, in order to facilitate sales, they are mainly added to the filling bottle through a filling head. Currently, the filling head mainly operates by direct injection. As the liquid veterinary medicine comes into contact with the bottom of the filling bottle, foam is easily generated, which affects the filling effect of the veterinary medicine.

[0004] Based on this, we propose a foam-free liquid filling head for concentrated traditional Chinese veterinary medicines. Utility Model Content

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] like Figures 1-5 As shown, this embodiment proposes a foam-free liquid filling head for concentrated veterinary drugs, including a veterinary drug inlet tube 1, a dispensing tube 2 fixedly connected to the bottom end of the veterinary drug inlet tube 1, a plurality of filling tubes 3 fixedly connected to the outside of the dispensing tube 2, a negative pressure tube 4 fixedly connected to the outside of the veterinary drug inlet tube 1, a sealing piece 5 fixedly connected to the outside of the negative pressure tube 4, a negative pressure channel 6 formed between the negative pressure tube 4 and the outer wall of the veterinary drug inlet tube 1, and a liquid level feedback component 7 provided at the bottom end of the dispensing tube 2, the liquid level feedback component 7 being used to provide feedback on the filling liquid level of the veterinary drug;

[0026] In this embodiment, the bottom end of the negative pressure channel 6 has an opening;

[0027] In this embodiment, the end of each filling tube 3 away from the dispensing tube 2 is bent downwards. By bending the filling tube 3, the traditional Chinese veterinary medicine can be applied to the inner wall of the filling bottle and flow downwards through the inner wall, avoiding the generation of foam.

[0028] In this embodiment, a sealing groove is provided at the bottom end of the sealing piece 5, and a sealing ring is fixedly connected inside the sealing groove. By setting the sealing ring, the bottle opening can be sealed when the sealing piece 5 contacts the bottle opening of the filling bottle, so as to prevent external gas from entering the filling bottle.

[0029] The liquid level feedback component 7 includes an extension plate 8, a guide slide rod 9, and a feedback plate 10. Both ends of the dispensing tube 2 are fixedly connected to the extension plate 8. The middle of the two extension plates 8 is vertically slidably connected to the guide slide rod 9. The top of the two guide slide rods 9 is fixedly connected to the feedback plate 10. The bottom of the two guide slide rods 9 is fixedly connected to the float plate 11. A flow control component is provided between the float plate 11 and the filling tube 3. The flow control component is used to control the opening and closing of the filling tube 3. A pressure sensor 12 is fixedly connected to the bottom of the outer side of the negative pressure tube 4.

[0030] In this embodiment, the float 11 has a hollow structure. Through the structural arrangement of the float 11, the weight of the float 11 can be reduced to the maximum extent, so that the float 11 can float on the Chinese veterinary medicine.

[0031] Example 2

[0032] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a flow control component;

[0033] In this embodiment, the flow control assembly includes a flow control shaft 13, a flow control plate 14, and an eccentric plate 15. A flow control shaft 13 is rotatably connected to one side of each filling tube 3. A flow control plate 14 is fixedly connected to one end of the flow control shaft 13 inside the filling tube 3, and an eccentric plate 15 is fixedly connected to one end of the flow control shaft 13 outside the filling tube 3. An assembly seat 16 corresponding to the eccentric plate 15 is fixedly connected to the top of the float 11. A linkage rod 17 is rotatably connected to the top of the assembly seat 16, and the end of the linkage rod 17 away from the assembly seat 16 is also rotatably connected to the corresponding eccentric plate 15.

[0034] In this embodiment, a rubber ring is fixedly connected to the outer side of the flow control plate 14, and the rubber ring and the inner wall of the filling tube 3 are in transition fit. By setting the rubber ring, the gap between the flow control plate 14 and the inner wall of the filling tube 3 can be reduced to the greatest extent, so as to prevent the veterinary medicine from flowing out from the gap between the flow control plate 14 and the filling tube 3.

[0035] In this embodiment, an assembly rod is fixedly connected to one end of the eccentric plate 15 away from the flow control shaft 13, and the end of the linkage rod 17 away from the assembly seat 16 is rotatably connected to the assembly rod. By setting the assembly rod, the linkage rod 17 can be effectively assembled, so that the linkage rod 17 can smoothly link between the eccentric plate 15 and the assembly seat 16.

[0036] A specific application of the above two embodiments is to connect the pressure sensor 12 to the control center of the filling machine, connect the veterinary drug inlet tube 1 to the external Chinese veterinary drug transmission pipeline, and connect the vacuum pump to the negative pressure tube 4. Then, the filling machine moves the dispensing tube 2 and the filling tube 3 into the filling bottle and seals the bottle mouth with the sealing piece 5.

[0037] The vacuum pump is started to extract the gas from the filling bottle, creating a negative pressure environment inside the bottle. Due to the presence of negative pressure, the veterinary medicine at the veterinary drug inlet tube 1 can flow naturally into the filling bottle, avoiding the formation of foam. As the liquid level in the filling bottle rises, the float plate 11 will float on the liquid level and follow the change in liquid level, pushing the feedback plate 10 towards the negative pressure channel 6 under the support of the guide slide rod 9. When the filling reaches the maximum liquid level, the feedback plate 10 will contact the pressure sensor 12, and the negative pressure channel 6 will adsorb the feedback plate 10 at its bottom, causing the negative pressure inside the filling bottle to be lost, thereby stopping the filling of the veterinary medicine.

[0038] Meanwhile, since the linkage rod 17 is connected between the assembly base 16 and the eccentric plate 15, when the assembly base 16 moves with the float 11, it can push the eccentric plate 15 with the help of the linkage rod 17. Since the eccentric plate 15 is supported by the flow control shaft 13, it can drive the flow control plate 14 to rotate through the flow control shaft 13. When the feedback plate 10 reaches the bottom of the negative pressure channel 6, the flow control plate 14 will simultaneously block the filling tube 3 to prevent the veterinary medicine from flowing out.

[0039] When the pressure sensor 12 is pressurized, it means that the filling is complete, and then the veterinary drug inlet tube 1 can be removed from the filling bottle.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
