Abstract
Description
Technical Field
[0001] This utility model relates to the field of filling equipment technology, specifically to a device for adjusting the filling liquid level. Background Technology
[0002] In the field of liquid filling, traditional filling equipment generally suffers from technical bottlenecks such as insufficient filling accuracy, high risk of liquid splashing, and poor container adaptability. The single liquid level sensor control system commonly used in existing technologies can only achieve a "one-size-fits-all" start and stop when the liquid level reaches the threshold. It cannot adjust the flow rate according to the dynamic changes in the filling process, which causes the liquid to splash due to inertia during the high-speed jet stage. This not only wastes materials but may also pollute the production environment. In addition, the sensor positions of traditional equipment are mostly fixed. When it is necessary to adapt to different container sizes or adjust the filling liquid level, it is often necessary to disassemble and replace the sensor bracket, which is cumbersome and inefficient.
[0003] In terms of sealing structure, most existing filling equipment adopts rigid connection method, such as directly fixing the container mouth with threads or buckles. This design is difficult to adapt to containers of different heights or shapes, and is prone to seal failure due to uneven pressure, causing liquid to overflow or external contaminants to enter. Although some equipment has tried to introduce elastic elements, they are mostly used to assist the movement of components rather than to directly act on the dynamic sealing of the container mouth. Therefore, in practical applications, there is still a problem of insufficient sealing stability. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a device for adjusting the filling liquid level, which solves the problems of easy leakage of liquid due to high-speed spraying and splashing during filling, insufficient filling accuracy, poor adaptability due to fixed position of liquid level sensor, and poor sealing of container mouth and difficulty in adapting to different specifications of containers in traditional filling equipment.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a device for adjusting the filling liquid level, including a positioning seat, a delivery pipe inserted into the bottom of the positioning seat, a flexible tube inserted into the top of the positioning seat, two liquid level sensors provided on the outer surface of the delivery pipe, a compression spring fixedly installed at the bottom of the positioning seat, and a pressure cap fixedly installed at the other end of the compression spring.
[0008] Optionally, one end of the hose that penetrates the positioning seat is connected to the inner wall of the delivery pipe.

[0013] Optionally, the top of the pressure plate is threaded with multiple fixing bolts, and one end of the fixing bolts protruding from the pressure plate is threadedly connected to the top of the positioning ring.
[0014] (III) Beneficial Effects
[0015] This utility model provides a device for adjusting the filling liquid level, which has the following beneficial effects:
[0016] This device for regulating the filling liquid level, through the coordinated arrangement of the delivery pipe and two liquid level sensors, can reduce the filling speed after the liquid reaches the first liquid level sensor, thereby preventing splashing and leakage caused by high-pressure jetting during filling, thus improving the practicality of the technical solution. When the liquid level reaches the other liquid level sensor, filling is immediately stopped, thus completing the filling process. Furthermore, the height and position of the two liquid level sensors can be adjusted according to different filling requirements, thereby improving the applicability of the technical solution. In addition, the compression spring at the bottom of the positioning seat, together with the pressure cap, can form an elastic pressure on the container opening during filling, ensuring the sealing of the filling process, reducing liquid spillage or external contamination, and adapting to the pressure requirements of different container sizes, thus improving the applicability and stability of the device.

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a device for adjusting the filling liquid level, including a positioning seat 1, a conveying pipe 2 inserted into the bottom of the positioning seat 1, a flexible tube 3 inserted into the top of the positioning seat 1, two liquid level sensors 6 provided on the outer surface of the conveying pipe 2, a compression spring 7 fixedly installed at the bottom of the positioning seat 1, and a pressure cap 8 fixedly installed at the other end of the compression spring 7.
[0024] In this embodiment, the positioning seat 1 serves as the core support structure of the device, used to connect and fix components such as the delivery pipe 2, hose 3, compression spring 7, and connecting rod 9, achieving integrated assembly of each component. A unified positioning reference ensures the relative stability of each component, guaranteeing the coordinated operation of functions such as liquid delivery, liquid level detection, and sealing during the filling process, thus improving the overall stability of the device. The delivery pipe 2, as the direct channel for liquid delivery, has one end inserted into the positioning seat 1 and the other end extending into the container to be filled, receiving the liquid delivered by the hose 3 and guiding it into the container, achieving directional delivery of the liquid from the supply system to the container. It is the core flow channel for the filling operation, and its structural design directly affects the stability of liquid delivery. The hose 3 connects the external supply device to the delivery pipe 2, communicating with the delivery pipe 2 through the internal channel of the positioning seat 1, providing a flexible delivery path for the liquid. Utilizing the bendability of the hose 3, it adapts to positional changes during lifting or adjustment, reducing the limitations imposed by rigid connections on equipment movement. This design enhances the flexibility and adaptability of the device layout. Two liquid level sensors 6 detect the liquid level at different heights within the container. When the first sensor is triggered, the filling speed is reduced; when the second sensor is triggered, the filling is stopped. This allows for precise, phased control of the filling process, preventing liquid splashing during high-speed filling and reducing material waste and contamination. Dual detection ensures accurate liquid level and improves filling quality. A compression spring 7 connects the bottom of the positioning seat 1 to the cap 8, providing elastic pressure. This allows the cap 8 to adaptively adjust its clamping force according to the container height. By compensating for height differences between different containers through elastic deformation, the cap 8 ensures stable clamping of the container opening while avoiding damage to the container from rigid pressure. This improves sealing reliability and equipment compatibility. Under the elastic force of the compression spring 7, the cap 8 directly contacts the container opening, forming a sealing structure that closes the gap between the container opening and the delivery pipe 2. This prevents liquid overflow or external contaminants from entering during filling, ensuring a clean filling environment and enhancing operational safety.
[0025] In the above embodiments, as a preferred option, one end of the hose 3 that penetrates into the positioning seat 1 is connected to the inner wall of the delivery pipe 2.
[0026] In the above embodiment, as a preferred solution, two fixing rings 4 are sleeved on the outer surface of the delivery pipe 2. One side of the outer surface of the two fixing rings 4 is fixedly installed with two liquid level sensors 6 respectively. The fixing rings 4 are sleeved on the outer surface of the delivery pipe 2 to fix the liquid level sensors 6. They are the connecting carrier between the liquid level sensors 6 and the delivery pipe 2, and stably install the liquid level sensors 6 on the delivery pipe 2. At the same time, they provide a basic structure for the position adjustment of the sensors, ensuring that the sensors can accurately align with the detection liquid level in the container.
[0027] In the above embodiment, as a preferred solution, fastening bolts 5 are threaded through the other side of the outer surface of the two fixing rings 4. One end of the fastening bolt 5 is inserted into the fixing ring 4 and abuts against the outer wall of the conveying pipe 2. By fastening the bolt 5 on the fixing ring 4 and tightening it against the outer wall of the conveying pipe 2, the position of the fixing ring 4 on the conveying pipe 2 is locked. By loosening or tightening the bolts, the height of the fixing ring 4 and the liquid level sensor 6 can be flexibly adjusted to meet different filling liquid level requirements. The operation is simple and improves the adaptability of the device to containers of different specifications.
[0028] In the above embodiments, as a preferred solution, a connecting rod 9 is fixedly connected to the top of the positioning seat 1, and a positioning ring 10 is fixedly connected to the top of the connecting rod 9. The top of the positioning seat 1 and the positioning ring 10 are connected by the connecting rod 9, forming a rigid connection between the positioning seat 1 and the hydraulic drive structure above, transmitting the driving force of the hydraulic rod 11 to the positioning seat 1, realizing the synchronous lifting and lowering of the entire filling assembly, ensuring consistent movement. The positioning ring 10 serves as the connection medium between the connecting rod 9 and the pressure plate 12, and indirectly connects the positioning seat 1 and the hydraulic rod 11 through a detachable structure, providing a stable installation reference for the positioning seat 1, ensuring that the overall force of the device is balanced when the hydraulic rod 11 is driven, and improving the stability of the lifting process.
[0029] In the above embodiments, as a preferred option, a hydraulic rod 11 is also included. A pressure plate 12 is fixedly installed at the output end of the hydraulic rod 11. The bottom end of the pressure plate 12 is detachably connected to the top of the positioning ring 10. Power output is provided through the hydraulic rod 11. The pressure plate 12 and the positioning ring 10 and positioning seat 1 below it are raised and lowered by telescopic drive, realizing the automatic adjustment of the device height, adapting to the filling needs of containers of different heights, reducing manual operation, and improving production efficiency. The pressure plate 12 connects the output end of the hydraulic rod 11 and the positioning ring 10, transmitting the driving force of the hydraulic rod 11, increasing the force-bearing area, and making the power of the hydraulic rod 11 evenly applied to the positioning ring 10, avoiding component deformation caused by excessive local force, and ensuring driving stability.
[0030] In the above embodiment, as a preferred solution, the top of the pressure plate 12 is threaded with a plurality of fixing bolts 13. One end of the fixing bolts 13 protrudes from the pressure plate 12 and is threadedly connected to the top of the positioning ring 10. By the fixing bolts 13 passing through the pressure plate 12 and being threadedly connected to the positioning ring 10, the pressure plate 12 and the positioning ring 10 can be detachably fixed, which facilitates the installation, disassembly and maintenance of the positioning seat 1 and the hydraulic rod 11, while ensuring the connection strength and ensuring that no relative displacement occurs during the driving process.
[0031] In this invention, the working steps of the device are as follows:
[0032] 1. According to the specifications of the container to be filled, adjust the height of the two liquid level sensors 6 on the delivery pipe 2 by loosening the fixing bolts 13 on the fixing ring 4, set the first sensor as the deceleration threshold and the second sensor as the stop threshold, and tighten the bolts to fix them after adjustment; at the same time, adjust the initial height of the positioning seat 1 and the delivery pipe 2 by extending and retracting the hydraulic rod 11 to match the height of the container.
[0033] 2. Place the container at the filling station and start the hydraulic rod 11. Its output end drives the connecting rod 9 and the positioning seat 1 to descend as a whole through the pressure plate 12 and the positioning ring 10, so that the pressure cap 8 contacts the container opening. The compression spring 7 is compressed and generates elastic force, which presses the pressure cap 8 tightly against the container opening to form a seal. At the same time, the lower end of the delivery pipe 2 extends into the container to a preset depth.
[0034] 3. The external liquid supply system delivers liquid to the delivery pipe 2 through the hose 3. The liquid is then injected into the container through the delivery pipe 2, and high-speed filling begins.
[0035] 4. When the liquid level in the container rises to the first liquid level sensor 6, the sensor triggers a signal, and the system controls the liquid supply speed to reduce to avoid liquid splashing; continue filling until the liquid level touches the second liquid level sensor 6, the sensor triggers a signal again, the system stops the liquid supply, and completes accurate filling.
[0036] 5. After filling is completed, the hydraulic rod 11 retracts, driving the positioning seat 1 and related components to rise, the pressure cap 8 disengages from the container opening, and the compression spring 7 returns to its original position; after removing the filled container and replacing it with a new container, repeat steps 2-4 to enter the next round of filling.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
