Abstract
Description
Technical Field
[0001] This utility model relates to the field of water injection technology in bottling production lines, and in particular to a water injection device for bottling production lines. Background Technology
[0002] The water injection unit in a bottling line is a device used to accurately inject water or other liquids into containers at a predetermined quantity. It typically includes components such as a water tank, pump, flow meter, control valve, and connecting pipes. The water injection unit can automatically control the water injection rate according to a set program, ensuring that the liquid level in each container reaches the standard. During operation, the water injection unit detects the container's position using sensors, then activates the pump to inject liquid into the container until the preset amount is reached. This device is widely used in the beverage, food, and chemical industries and is an indispensable part of bottling lines.
[0003] In practical applications, if there is gas in the filling pipes or water tank of the water injection device in the filling production line, this gas will cause water to splash when it flows out of the filling head. This splashing has several disadvantages: First, it affects the accuracy of filling, as splashing may cause the filling volume to be too high or too low; second, splashed water droplets may contaminate the filling area, increasing the workload of cleaning and maintenance; finally, splashing may also pose safety risks to operators, such as slipping and falling.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A water injection device for a bottling production line includes a production line support, a conveyor belt, a blocking strip, a mounting frame, a water tank, a water supply pipe, a connecting pipe, a bottling control mechanism, and a bottling head. The conveyor belt is mounted on the production line support, the blocking strip is located on the side wall of the conveyor belt, the mounting frame is located next to the production line support, the water tank and the bottling control mechanism are mounted on the mounting frame, a water supply pipe is provided between the water tank and the bottling control mechanism, and the bottling head is connected to the water supply pipe through the connecting pipe.
[0007] The production line support is provided with a base next to it, and a telescopic push rod is installed on the upper end of the base. The telescopic end of the telescopic push rod is connected to a limit block, which is set directly opposite the filling head to restrict the filling container at the filling head.
[0008] The upper end of the water supply pipeline is equipped with an exhaust pipe, and the upper end of the exhaust pipe is connected to an exhaust valve through a connector. The exhaust valve allows gas to be released through the water supply pipeline and the filling head.
[0009] In an optional embodiment of this utility model, the blocking strip is mounted on the production line support via a vertical rod. The blocking strip is a round tube with a smooth surface. The mounting bracket and the base are designed opposite each other and are located on the side of the conveyor belt.
[0010] In an optional embodiment of this utility model, the telescopic push rod is mounted on the base via a support frame. The telescopic end of the telescopic push rod passes through the limiting block and is fixed to the telescopic end of the telescopic push rod with a nut. The outer end of the limiting block has an arc-shaped notch, and a rubber strip is bonded to the surface of the arc-shaped notch. The arc-shaped notch is adapted to the size of the filling container.
[0011] In an optional embodiment of this utility model, the water tank is fixed to the mounting frame with bolts, the water supply pipe is connected to the water tank through a connecting flange, a sealing ring is provided at the connection between the water supply pipe and the water tank, and the exhaust pipe and the water supply pipe are designed as an integral part.
[0012] In an optional embodiment of this utility model, the cross-section of the exhaust pipe is U-shaped, the exhaust pipe and the connector are integrated, the connector and the exhaust valve are fixed by bolts, and a sealing ring is provided at the connection between the connector and the exhaust valve.
[0013] In an optional embodiment of this utility model, one end of the exhaust pipe is directly opposite the connecting pipe, and the other end of the exhaust pipe is located at the tail end of the water supply pipe.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] When performing liquid filling operations, it is essential to first purge the air from the water supply pipeline and filling head, as the presence of this air can adversely affect the accuracy of the filling process. To effectively remove this air, a venting pipe with a "U"-shaped design is employed. This design ensures smooth airflow, preventing stagnation or accumulation within the pipes. The layout of the venting pipe is carefully designed to ensure complete venting from the entire filling system, creating an airless environment for the filling process. Once the venting process is complete, the vent valve closes promptly, ensuring both the accuracy of the filling process and improving the efficiency of the filling operation.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figure 1 - Figure 4 As shown, a water injection device for a bottling production line mainly consists of a production line support 1, a conveyor belt 2, a blocking strip 3, a mounting frame 7, a water tank 8, a water supply pipe 9, a connecting pipe 10, a bottling control mechanism 11, and a bottling head 12. The conveyor belt 2 is mounted on the production line support 1, the blocking strip 3 is located on the side wall of the conveyor belt 2, and the mounting frame 7 is located beside the production line support 1. The water tank 8 and the bottling control mechanism 11 are mounted on the mounting frame 7, and a water supply pipe 9 connects the water tank 8 and the bottling control mechanism 11. The bottling head 12 is connected to the water supply pipe 9 via the connecting pipe 10. This design makes the bottling process more efficient and precise, while ensuring the stable operation of the production line.
[0023] A base 4 is located next to the production line support 1. A telescopic push rod 5 is installed on the upper end of the base 4. The telescopic end of the telescopic push rod 5 is connected to a limit block 6, which is positioned directly opposite the filling head 12, thus restricting the filling container at the filling head 12. This design effectively controls the movement of the filling head 12, ensuring the accuracy and consistency of the filling process. An exhaust pipe 13 is located at the upper end of the water supply pipe 9. An exhaust valve 15 is connected to the upper end of the exhaust pipe 13 via a connector 14, allowing the release of gas from the water supply pipe 9 and the filling head 12. This design effectively eliminates gas from the water supply pipe 9 and the filling head 12, preventing gas from affecting the filling process.
[0024] The blocking strip 3 is mounted on the production line support 1 via a vertical rod. The blocking strip 3 is a round tube with a smooth surface. The mounting bracket 7 and base 4 are positioned opposite each other and located on the side of the conveyor belt 2. This design effectively prevents the filling containers from sliding or tipping over during transport. The telescopic push rod 5 is mounted on the base 4 via a support frame. The telescopic end of the telescopic push rod 5 passes through the limiting block 6 and is fixed to the telescopic end of the push rod 5 with a nut. The outer end of the limiting block 6 has an arc-shaped notch, and a rubber strip is bonded to the surface of the arc-shaped notch. The arc-shaped notch is adapted to the size of the filling container. This design effectively controls the movement of the filling container, ensuring the accuracy and consistency of the filling process.
[0025] The water tank 8 is bolted to the mounting bracket 7. The water supply pipe 9 is connected to the water tank 8 via a connecting flange. A sealing ring is provided at the connection between the water supply pipe 9 and the water tank 8. The vent pipe 13 is integrated with the water supply pipe 9. The vent pipe 13 has a U-shaped cross-section and is integrated with the connector 14. The connector 14 is bolted to the vent valve 15, and a sealing ring is provided at the connection between the connector 14 and the vent valve 15. One end of the vent pipe 13 is directly opposite the connecting pipe 10, and the other end of the vent pipe 13 is located at the tail end of the water supply pipe 9. This design can effectively remove gas from the water supply pipe 9 and the filling head 12, preventing gas from affecting the filling process.
[0026] Water filling process: First, the filling container is conveyed to the position of the blocking bar 3 via the conveyor belt 2. The blocking bar 3 prevents the container from sliding or tipping over during conveying, ensuring the stability and safety of the filling process. Next, under the precise control of the limit block 6, the telescopic push rod 5 accurately positions the filling container below the filling head 12, preparing for the subsequent water filling step. After the filling container is positioned, the filling control mechanism 11 is activated. Water in the water tank 8 is transported to the filling head 12 through the water supply pipe 9 under the action of the control mechanism, ready for water filling. Under the command of the control mechanism, the filling head 12 begins to fill the container below, continuing until the predetermined filling volume is reached, ensuring that each container is filled to the specified capacity.
[0027] During venting: Before filling begins, the vent valve 15 opens to remove gas from the water supply pipe 9 and filling head 12, preventing gas from affecting the accuracy and efficiency of filling. The vent pipe 13 is designed in a "U" shape, which facilitates the smooth discharge of gas and prevents gas from stagnating in the pipe. One end of the vent pipe 13 is directly connected to the connecting pipe 10, while the other end is located at the end of the water supply pipe 9. This layout ensures that gas can be completely discharged from the entire system, creating an airless environment for the filling process. Once the venting process is successfully completed, the vent valve 15 closes, and the filling process officially begins. Water is injected into the pre-positioned filling container, completing the entire water filling process.
