Description

Technical Field

[0001] This utility model relates to the field of quantitative liquid dispensing technology, specifically a quantitative liquid dispensing structure for a vaccine suspension filling machine. Background Technology

[0002] To ensure consistency in the filled products, the filling valves installed on the filling production line are usually designed for metered dispensing. For large-volume filling products, different manufacturers have different tolerance requirements, but they are generally required to have a tolerance of no more than 5 ml. Within this tolerance range, the filling volume can be controlled by the filling time. However, for small vials of liquid medicine, due to the small capacity of the liquid container itself, the required tolerance range is also small, making it difficult to control the filling volume by the filling time.

[0003] In the vaccine production process, the filling of vaccine suspensions is a crucial step. Traditional vaccine suspension filling machines have some problems in terms of quantitative dispensing, such as inaccurate dispensing volume and unstable dispensing speed, which can easily affect vaccine quality and production efficiency.

[0004] Therefore, this utility model provides a quantitative liquid dispensing structure for a vaccine suspension filling machine to solve the above problems. Utility Model Content

[0026] 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.

[0027] This utility model provides a quantitative dispensing structure for a vaccine suspension filling machine, such as... Figure 1-4As shown, the quantitative dispensing structure of the vaccine suspension filling machine includes a positioning frame 1. Two sets of sliding supports 2 are fixedly installed at the front end of the positioning frame 1. A scissor-type extension frame 3 is provided between the two sets of sliding supports 2. Guide rails 9 are fixedly installed at the front end of both sets of sliding supports 2. Multiple sets of connectors 10 are installed at the front end of the scissor-type extension frame 3. Mounting plates 11 are fixedly installed on the front side of each set of connectors 10. A drive assembly is provided inside the positioning frame 1. Quantitative dispensing components are provided on each of the multiple mounting plates 11.

[0028] In practical applications, the operator can drive multiple sets of connectors 10, multiple sets of mounting plates 11 and quantitative dispensing components to move in an orderly manner through the drive components, thereby adjusting the spacing between multiple sets of quantitative dispensing components, which facilitates filling of vaccine bottles with different gaps, improves the adaptability and flexibility of the equipment, and realizes quantitative filling of vaccines through multiple sets of quantitative dispensing components.

[0029] The drive assembly includes an adjustment motor 4, which is fixedly installed in the positioning frame 1. An adjustment screw 5 is installed on the output shaft of the adjustment motor 4. A slider 6 is threaded onto the adjustment screw 5. Connecting rods 7 are fixedly installed on both the upper and lower sides of the slider 6. Guide grooves 8 are provided on both sets of sliding brackets 2. The two sets of connecting rods 7 are slidably inserted into the two sets of guide grooves 8.

[0030] When the regulating motor 4 starts, its output shaft drives the regulating screw 5 to rotate. Since the slider 6 and the regulating screw 5 are connected by a threaded sleeve, the slider 6 will move along the axial direction of the regulating screw 5 under the rotation of the regulating screw 5, thereby driving the two sets of connecting rods 7 to slide in the two sets of guide grooves 8, so as to realize the orderly driving and adjustment of multiple sets of connecting parts 10, multiple sets of mounting plates 11 and quantitative liquid dispensing components.

[0031] The front end of the scissor-type extension frame 3 and the upper and lower sides of the multiple sets of connectors 10 are slidably connected to the opposite side of the two sets of guide rails 9.

[0032] In practical applications, the multiple sets of connectors 10, multiple sets of mounting plates 11, and quantitative dispensing components can slide stably under the guidance of the two sets of guide rails 9 under the action of the driving component, ensuring the precise relative position between the components and improving the filling accuracy.

[0033] The quantitative dispensing assembly includes two sets of fixing brackets 12 and a filling tube 13. The two sets of fixing brackets 12 are fixedly installed on the front side of the mounting plate 11. The filling tube 13 is fixedly installed on the fixing bracket 12 on the lower front side of the mounting plate 11. A filling needle 15 is provided at the lower end of the filling tube 13. A second drive cylinder 19 is fixedly installed on the fixing bracket 12 on the lower front side of the mounting plate 11. A second push rod 20 is installed at the upper end of the second drive cylinder 19. A slide plate 21 is installed at the upper end of the second push rod 20. A piston rod 22 is fixedly installed on the lower right side of the slide plate 21. A quantitative piston 23 is fixedly installed at the lower end of the piston rod 22. The quantitative piston 23 is movably inserted into the filling tube 13.

[0034] In practical applications, the second drive cylinder 19 drives the slide plate 21 to rise and fall through the second push rod 20. The slide plate 21 drives the piston rod 22 to rise and fall. The piston rod 22 drives the quantitative piston 23 to rise and fall within the filling tube 13. When the quantitative piston 23 rises and falls to the designated position, the vaccine suspension flows into the vaccine bottle through the filling needle 15 at the lower end of the filling tube 13.

[0035] A liquid outlet valve 14 is provided at the connection between the lower end of the filling tube 13 and the filling needle 15. A first drive cylinder 16 is installed on the front right side of the mounting plate 11. A first push rod 17 is installed at the lower end of the first drive cylinder 16. A valve rod 18 is provided on the right side of the liquid outlet valve 14. The first push rod 17 and the valve rod 18 are rotatably connected.

[0036] In practical applications, the operator can rotate the first push rod 17, which rotates under the action of the valve rod 18, thereby adjusting the opening at the lower end of the filling tube 13 through the liquid outlet valve 14, thus improving the filling accuracy and flexibility.

[0037] The front middle part of the filling tube 13 is transparent.

[0038] The transparent design at the front center of the filling tube 13 allows the operator to directly observe the liquid level of the vaccine suspension inside the filling tube 13, facilitating monitoring and control of the liquid output and ensuring filling accuracy.

[0039] The front surface of the filling tube 13 has a scale.

[0040] The scale design allows operators to more accurately read and control the volume of vaccine suspension dispensed, further improving the accuracy and reliability of filling.

[0041] A guide rod 24 is fixedly installed between the upper side of the second drive cylinder 19 and the fixing bracket 12 at the upper end of the mounting plate 11, and the slide plate 21 is slidably sleeved on the guide rod 24.

[0042] In practical applications, the guide rod 24 guides and stabilizes the lifting and lowering movement of the slide plate 21, ensuring the stability and accuracy of the slide plate 21 during the lifting and lowering process, thereby ensuring the accuracy of the lifting and lowering movement of the quantitative piston 23 in the filling tube 13 and improving the accuracy of vaccine suspension filling.

[0043] The outer wall of the metering piston 23 is provided with a wear-resistant sealing coating, and the metering piston 23 is fitted with the inner wall of the filling tube 13 with a clearance of 0.05-0.1mm.

[0044] The wear-resistant sealing coating design improves the sealing performance between the metering piston 23 and the inner wall of the filling tube 13, while reducing wear and extending the service life of the components. Precise control of the gap value ensures the stability and accuracy of the vaccine suspension during the flow process, avoids leakage and waste, and further improves the accuracy and efficiency of filling.

[0045] An angle limiting structure is provided at the connection between the first push rod 17 and the valve rod 18, with a limiting angle range of 0°-90°.

[0046] The angle limiting structure design ensures the stability and accuracy of the first push rod 17 during rotation, avoiding over-rotation or under-rotation, and further improving filling accuracy and reliability. Meanwhile, the limiting angle range of 0°-90° can meet different filling needs, improving the flexibility and adaptability of the equipment.

[0047] Working Principle: In practical application, the operator first starts the adjusting motor 4 according to the specifications of the vaccine vial and the filling requirements. Its output shaft drives the adjusting screw 5 to rotate. Since the slider 6 is threadedly connected to the adjusting screw 5, the slider 6 moves along the axial direction of the adjusting screw 5 under the rotation of the adjusting screw 5, thereby driving the two sets of connecting rods 7 to slide in the two sets of guide grooves 8, thus expanding the left and right ends of the scissor-type expansion frame 3. At the same time, the multiple sets of connecting parts 10 and multiple sets of mounting plates 11 at the front end of the scissor-type expansion frame 3 slide stably under the guidance of the two sets of guide rails 9, realizing the precise adjustment of the position of multiple sets of quantitative dispensing components. After the adjustment is completed, the operator places the vaccine vial in the designated position, ready for filling. At this time, the second drive cylinder 19 drives the slide plate 2 through the second push rod 20. 1. The slide plate 21 drives the piston rod 22 to move up and down. The piston rod 22 further drives the metering piston 23 to move up and down within the filling tube 13. When the metering piston 23 moves up and down to the designated position, the vaccine suspension flows into the vaccine bottle through the filling needle 15 at the lower end of the filling tube 13. The operator can intuitively monitor and control the liquid level and output of the vaccine suspension by observing the transparent part and scale value on the front side of the filling tube 13, ensuring the accuracy of filling. During the filling process, the operator can rotate the first push rod 17. The first push rod 17 rotates under the rotational connection of the valve rod 18, and then adjusts the opening at the lower end of the filling tube 13 through the outlet valve 14 to control the flow rate and filling speed of the vaccine suspension, thereby improving the accuracy and flexibility of filling.

[0048] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
