Description

Technical Field

[0001] This utility model relates to the technical field of filling machines, specifically a filling machine that avoids liquid spillage. Background Technology

[0002] Filling machines are a small category of packaging machines. From the perspective of packaging materials, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. Filling machines are needed when processing pharmaceutical liquids.

[0003] A search revealed that a typical example of an existing filling machine is disclosed in CN215048593U, which describes a liquid preparation filling machine. This machine includes a buffer tank, an inlet pipe, and a filling mechanism connected sequentially within an isolator. The outlet of the buffer tank is connected to the inlet of the inlet pipe via an inlet pump. The inlet pipe has multiple outlets connected to the inlet of the filling mechanism via distributors. A support is installed along the path of the inlet pipe, vertically and fixedly within the isolator. Three horizontal supports are mounted on the support for placing the inlet pipe, with the supports positioned below the inlet of the inlet pipe. A breather is installed on the top of the buffer tank. By supporting the inlet pipe with a support, the inlet pipe is tilted downwards, which helps to significantly reduce air bubbles in the liquid during transport, thus improving the quality of the medicine.

[0004] In summary, existing filling machines are prone to spillage during use due to issues such as the rapid drop speed of the liquid and the misalignment between the filling head and the container. This results in pharmaceutical waste, pollution of the working environment, and compromises filling accuracy and product quality. Therefore, improvements to the existing equipment are necessary to address these problems. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a filling machine that avoids liquid medicine splashing, based on... Figure 1 , Figure 2 and Figure 3As shown, a mounting bracket 5 is connected to the upper end of the frame 1 via mounting screws. A liquid storage tank 6 is mounted on the top of the mounting bracket 5. An inlet pipe 601 is located in the middle of the top of the liquid storage tank 6. A stirring assembly 602 is located at the lower end of the interior of the liquid storage tank 6. The stirring assembly 602 facilitates the stirring of the liquid inside the liquid storage tank 6, achieving uniform mixing of the liquid, preventing clumping and sedimentation, and ensuring the uniformity and quality of the liquid. A level gauge 603 is located on one side of the front of the liquid storage tank 6, which allows for real-time monitoring of the liquid level inside the liquid storage tank 6. A connecting pipe 7 is located at the lower end of one side of the liquid storage tank 6. A first one-way valve 8 and an infusion pump 9 are sequentially mounted on the connecting pipe 7. The other end of the connecting pipe 7 passes through the mounting bracket 5 and connects to the horizontal pipe 10. The upper ends of the horizontal pipe 10 are connected to the mounting bracket 5 via symmetrically arranged electric telescopic rods 11. Multiple drainage components are equidistantly arranged at the bottom of the lower end of the tube 10. The horizontal tube 10 is raised and lowered by the electric telescopic rod 11, which facilitates the adjustment of the distance between the drainage components and the filling bottle 4, thereby improving the accuracy of filling. The drainage components include a metering pump 12, a gas-liquid separator 13, a drainage head 14, and a drainage hose 15. The gas-liquid separator 13 is located at the lower end of the metering pump 12. A vent head 16 is located on the front of the gas-liquid separator 13. The gas in the liquid is separated by the gas-liquid separator 13 and discharged from the vent head 16, which effectively avoids the generation of bubbles during filling and reduces the possibility of liquid splashing. The drainage head 14 is located at the bottom of the gas-liquid separator 13. A drainage hose 15 is located at the middle of the bottom of the drainage head 14. The liquid entering the filling bottle 4 flows slowly through the drainage hose 15, which effectively avoids splashing.

[0022] To further explain, a belt conveyor 2 is provided in the middle of the frame 1, and multiple rubber positioning seats 3 are equidistantly arranged on the conveyor belt of the belt conveyor 2. The belt conveyor 2 and the rubber positioning seats 3 are used together to facilitate the placement and fixation of the bottom of the canned bottle 4, while also conveying and moving the canned bottle 4. At the same time, multiple canned bottles 4 are installed equidistantly inside the rubber positioning seat 3. The position of the canned bottle 4 is on the same horizontal plane as the position of the corresponding drainage component, thereby improving the accuracy of filling.

[0023] according to Figure 1 and Figure 2 As shown, the mounting bracket 5 is located below the horizontal tube 10 and is equipped with a positioning component 17, which is used to position the canned bottle 4 to prevent it from shifting.

[0024] Specifically, the positioning component 17 includes an electric linear guide rail 1701, a movable slide 1702, a connecting long plate 1703, a connecting short plate 1704, and a limiting seat 1706. Two electric linear guide rails 1701 are symmetrically arranged, and movable slides 1702 are mounted on the two electric linear guide rails 1701. A connecting long plate 1703 is symmetrically arranged between the two movable slides 1702. Connecting short plates 1704 are symmetrically arranged on both sides between the two connecting long plates 1703. A first rubber pad 1705 is provided on the side of the connecting short plate 1704 closest to the limiting seat 1706, and multiple limiting seats 1706 are equidistantly arranged between the two connecting short plates 1704. 6. The electric linear guide rail 1701 drives the movable slide 1702, connecting long plate 1703, connecting short plate 1704 and limiting seat 1706 to move downward as a whole, which facilitates limiting the upper end of the canned bottle 4 and improves the stability of the canned bottle 4 during canning. At the same time, the limiting seat 1706 is connected to the connecting long plate 1703 in the middle through the positioning threaded rod 1707. The limiting seat 1706 is provided with second rubber pads 1708 on both sides. Through the first rubber pad 1705 and the second rubber pad 1708, when the connecting short plate 1704 and the limiting seat 1706 move downward to limit the upper end of the canned bottle 4, damage to the canned bottle 4 is avoided, thus improving the practicality of use.

[0025] In use, the canned bottles 4 are neatly arranged inside the rubber positioning seat 3, and then conveyed by the belt conveyor 2. When the canned bottles 4 are conveyed to the position component 17, the electric linear guide 1701 is activated, causing the moving slide 1702 to move the connecting long plate 1703, connecting short plate 1704, and limiting seat 1706 downward as a whole until the first rubber pad 1705 and the second rubber pad 1708 are in contact with the upper outer side of the canned bottles 4, limiting the position of the canned bottles 4. Then, the electric telescopic rod 11 is activated. Push the horizontal tube 10 and the drain assembly down until the drain hose 15 is inside the corresponding bottle 4. Then start the infusion pump 9, the metering pump 12 and the gas-liquid separator 13 so that the liquid medicine inside the storage tank 6 enters the horizontal tube 10 through the connecting pipe 7 and the first one-way valve 8. Then, through the metering pump 12 and the gas-liquid separator 13, the liquid medicine is metered and the gas in the liquid medicine is discharged through the vent head 16. Then the liquid medicine is discharged into the bottle 4 through the drain head 14 and the drain hose 15.
