[0022] Reference Figure 1-4 A filling structure for a filling machine includes a conveyor table 1, which is typically made of a robust metal material with a rust-proof surface to ensure its durability and reliability. Two symmetrically arranged side plates 2 are fixedly connected to the top of the conveyor table 1. The side plates 2 are made of the same material as the conveyor table 1 and are fixed to the conveyor table 1 by welding or bolting. A storage frame 3 is fixedly connected between the two side plates 2. A drive motor 4 is fixedly connected to the outer wall of the storage frame 3. An output shaft 5 is fixedly connected to the output end of the drive motor 4. The output shaft 5 passes through the storage frame 3 and is fixedly connected to multiple sets of stirring blades 6. The fixedly connected stirring blades 6 are designed according to the material characteristics, and the number, shape, and arrangement of the blades are optimized to ensure the best mixing effect. A discharge pipe 7 is provided at the bottom of the storage frame 3, and a vibration mechanism is provided on the storage frame 3. A metering cylinder 8 is fixedly connected between the side plates 2, and a metering mechanism is provided inside the metering cylinder 8.

[0023] The vibration mechanism includes two sliding plates 9 symmetrically arranged and slidably connected to the inner wall of the storage frame 3. The inner wall of the storage frame 3 is provided with two L-shaped air frames 10. The inner wall of the air frames 10 is slidably connected to the extrusion plate 11. The top of the extrusion plate 11 is fixedly connected to the extrusion rod 12, which passes through the air frame 10 and is fixedly connected to the bottom of the sliding plate 9. The inner wall of the air frame 10 is slidably connected to the piston plate 13. The outer wall of the piston plate 13 is fixedly connected to the through-running vibration rod 14. The end of the vibration rod 14 is fixedly connected to the vibration head 15. As the piston plate 13 moves, the vibration rod 14 and the vibration head 15 will also perform corresponding reciprocating motion synchronously. Through the transmission mechanism, the sliding plate 9 will periodically vibrate up and down, thereby driving the entire vibration mechanism to work effectively.

[0024] A return spring 16 is sleeved on the outer wall of the extrusion rod 12. The two ends of the return spring 16 are fixedly connected to the outer wall of the air frame 10 and the outer wall of the slide plate 9, respectively. The function of the return spring 16 is to provide elastic restoring force when the extrusion rod 12 moves up and down, so as to ensure that the extrusion rod 12 can return to its original position in time after completing the filling action, thus ensuring the stability and accuracy of the filling process.

[0025] The metering mechanism includes a metering shaft 17 that passes through a metering cylinder 8. Multiple baffles 18 are fixedly connected to the outer wall of the metering shaft 17. The baffles 18 fit against the inner wall of the metering cylinder 8. The metering shaft 17 is connected to the output shaft 5 through a transmission mechanism. The shape of the baffles 18 can be designed to be flat or cylindrical to adapt to different types of liquids and their flowability. At the same time, it ensures that the baffles 18 can fit tightly against the inner wall of the metering cylinder 8 during the rotation of the metering shaft 17 to prevent liquid leakage. In this way, the filling structure can not only achieve accurate liquid level measurement, but also improve the stability and efficiency of the entire filling process.

[0026] The first transmission wheel is fixedly connected to the outer wall of the output shaft 5, and the second transmission wheel is fixedly sleeved on the outer wall of the metering shaft 17. The first transmission wheel and the second transmission wheel are connected by a transmission belt 19, so that the movement between the two shafts can be synchronized, thereby ensuring the stability and reliability of the system. The tension of the transmission belt 19 needs to be adjusted appropriately to ensure that there is no slippage during the power transmission process, thereby improving the working efficiency and stability of the system.

[0027] The bottom of the metering cylinder 8 is equipped with a feed pipe 20. The design of the feed pipe 20 allows it to communicate with the inner cavity of the metering cylinder 8, thus ensuring that the material can pass through smoothly. The feed pipe 20 is equipped with a one-way discharge valve 21. When the internal pressure is greater than the external pressure, the valve opens, allowing the material to flow out; when the internal pressure is lower than the external pressure, the valve closes, preventing the material from flowing back.

[0028] The specific working principle of this utility model is as follows:

[0029] In actual operation, when this device is used, the material to be filled is first added from above the storage frame 3. The side plates 2 symmetrically arranged on both sides of the storage frame 3 play a role in supporting the entire filling structure. In order to prevent uneven sedimentation and clumping of the material, the drive motor 4 on the outer wall of the storage frame 3 drives the output shaft 5 to rotate. Multiple sets of stirring blades 6 are fixed on the output shaft 5, so as to fully stir the material in the storage frame 3, ensuring that the material is evenly distributed and has good fluidity. At the same time, the bottom of the storage frame 3 is provided with a discharge pipe 7. When filling is required, the discharge pipe 7 can control the flow rate and velocity of the material, so that the material can be stably delivered to the metering cylinder 8 below.

[0030] In addition, the storage box 3 is equipped with a vibration mechanism, which can generate periodic vibrations during the material filling process to help the material be discharged smoothly, avoid blockage problems, and ensure smooth material flow. The metering cylinder 8 is located in the center between the two side plates 2. When the material enters the metering cylinder 8 through the discharge pipe 7, the metering mechanism will accurately measure the amount of material conveyed each time to ensure that the amount of material in each packaging container is consistent. Finally, when the metering cylinder 8 rotates to the bottom, the material precisely controlled by the metering cylinder 8 will enter the filling bottle on the conveyor table 1 through the one-way discharge valve 21. Other equipment on the conveyor table 1 will then perform subsequent sealing, packaging and other processing to complete the entire filling process. This series of actions are coordinated to ensure the efficiency and accuracy of the filling process.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
