Description

Technical Field

[0001] This utility model relates to the field of filling technology, and in particular to a splash-proof sealing component for a filling head. Background Technology

[0002] The filling head is a key component in automated filling equipment for liquids, powders, and granular materials. It is responsible for accurately and quickly filling products into containers and is used in the food and beverage, chemical, pharmaceutical, and cosmetic industries. The design and function of the filling head directly affect the filling accuracy, speed, hygiene, and ease of operation. During the filling process, precise control of the liquid volume and prevention of splashing are required. Splash-proof sealing components for the filling head are typically used to ensure that liquid does not splash out during filling, while maintaining the equipment's airtightness and preventing liquid contamination.

[0003] The filling head splash seal assembly consists of multiple sealing components that form a tight seal between the filling head and the container opening, preventing liquid from spilling during the filling process. The sealing components effectively prevent liquid leakage through the contact surface, ensuring that liquid flows directly into the container without splashing.

[0004] In the prior art, some liquid remains in the delivery pipe after filling. Since the liquid flow cannot be stopped in time, the liquid will continue to leak downwards, causing waste. To address this problem, a splash-proof sealing assembly for the filling head is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a splash-proof sealing component for a filling head, which aims to improve the problem of liquid leakage caused by the inability to stop the liquid from continuing to flow in time after filling in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A splash-proof sealing assembly for a filling head includes a delivery pipe, an annular ring fixedly connected to the inner wall of the delivery pipe, a filling head fixedly connected to the inner wall of the delivery pipe, a spring fixedly connected to the top of the filling head, a circular plate fixedly connected to the top of the spring, and two limiting blocks fixedly connected to the inner wall of the delivery pipe.

[0008] As a further description of the above technical solution:

[0009] A connecting ring is fixedly connected to the bottom of the conveying pipe, and the connecting ring has multiple air outlets inside.

[0010] As a further description of the above technical solution:

[0011] The filling head is fixedly connected to a flexible plastic telescopic tube, and the top of the flexible plastic telescopic tube is fixedly connected to the bottom of the connecting ring.

[0012] As a further description of the above technical solution:

[0013] The bottom of the flexible plastic tube is provided with multiple vents, and the bottom of the filling head is provided with a filling port.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, when the filling system is started, the force of the spring is overcome by the impact of the liquid on the circular plate, causing the circular plate to move downward, allowing the liquid to flow into the filling head. After filling is completed, the force of the spring will take effect, and the spring will push the circular plate back to its original state. The circular plate and the ring close to ensure that the liquid stops flowing and prevent the liquid from continuing to leak and causing waste. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1 to 3This utility model provides an embodiment of a filling head anti-splash sealing assembly, including a delivery pipe 1, which is responsible for delivering liquid from the source to the filling head 3. The delivery pipe 1 is made of a chemically resistant material to ensure that the liquid will not damage the pipe wall during delivery. A ring 2 is fixedly connected to the inner wall of the delivery pipe 1. The ring 2 is used to limit the position of the circular plate 5. The ring 2 can be tightly closed with the circular plate 5 to prevent the liquid from continuing to flow. A filling head 3 is fixedly connected to the inner wall of the delivery pipe 1. The filling head 3 is the part of the structure from which the liquid flows out of the delivery pipe 1 and into the container. The filling head 3 can be inserted into the container opening. A spring 4 is fixedly connected to the top of the filling head 3. The spring 4 is used to provide elastic force to make the circular plate 5 tightly close with the ring 2. The circular plate 5 is fixedly connected to the top of the spring 4. The circular plate 5 can be tightly closed with the ring 2 by means of the elastic force of the spring 4 to prevent the liquid from flowing. Two limiting blocks 6 are fixedly connected to the inner wall of the delivery pipe 1. The limiting blocks 6 are used to limit the position of the circular plate 5 to prevent excessive liquid impact force from causing excessive deformation of the spring 4 and damage.

[0024] Reference Figures 3 to 4 A connecting ring 7 is fixedly connected to the bottom of the delivery pipe 1. The air vent 8 inside the connecting ring 7 allows air to escape to reduce pressure fluctuations during the filling process. The connecting ring 7 has multiple air vents 8 inside, which are used to release the gas generated during the filling process and maintain the continuity and stability of the liquid flow. A flexible plastic telescopic tube 9 is fixedly connected to the outside of the filling head 3. The flexible plastic telescopic tube 9 provides additional flexibility to adapt to different filling positions and angles. The top of the flexible plastic telescopic tube 9 is fixedly connected to the bottom of the connecting ring 7. The bottom of the flexible plastic telescopic tube 9 has multiple exhaust ports 10, which are used to release the air in the container during the filling process, maintain the normal air pressure inside the container, and make it easier for the liquid to be filled into the container. The bottom of the filling head 3 has a filling port 11, which is the final outlet for the liquid to flow from the filling head 3 into the container, ensuring that the liquid can be filled into the container evenly and accurately.

[0025] Working principle: When the filling head 3 is placed into the container opening, filling begins. The liquid flows in the delivery pipe 1 and impacts the circular plate 5, causing the circular plate 5 to detach from the surface of the ring 2 and move downwards. At the same time, the spring 4 will deform, and the liquid will enter the filling head 3 through the ring 2. The limiting block 6 can limit the range of motion of the circular plate 5 to prevent the spring 4 from being severely deformed and damaged. The flexible plastic tube 9 is in contact with the inner wall of the container opening. The liquid will enter the container through the filling head 3 from the filling opening 11. The air in the container will enter the interior of the flexible plastic tube 9 through the exhaust port 10 and then be discharged from the air outlet 8 on the connecting ring 7. The exhaust port 10 and the air outlet 8 can balance the air pressure inside the container, making it easier for the liquid to be filled into the container.

[0026] After filling is complete, spring 4 will return to its original shape and provide elastic force to push the circular plate 5, so that the circular plate 5 fits tightly with the circular ring 2, which can prevent the liquid from continuing to flow and prevent the liquid from leaking outside the container and causing waste.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
