Description

Technical Field

[0001] This utility model relates to the field of drug loading equipment, and more specifically, to an adjustable piston-type drug loading machine. Background Technology

[0002] Piston-type dispensing machines, as a key quantitative dispensing device, are widely used in pharmaceutical, chemical, and other industries involving the handling of liquid or semi-solid materials. Their working principle is based on the reciprocating motion of a piston within a sealed chamber. By precisely controlling the piston's position, the amount of liquid dispensed each time is kept consistent, thus achieving efficient and accurate dispensing of liquid drugs or other fluid materials.

[0003] However, in traditional piston-type drug loading machines, adjusting the loading amount is often relatively cumbersome and inflexible. To adjust the loading amount, operators usually need to replace pistons of different sizes or make tedious adjustments to the piston's stroke. This adjustment method not only consumes a lot of time and manpower, but its adjustment range is also relatively limited, making it difficult to meet the needs of dispensing different specifications and types of liquid drugs.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The one-way valve 8 precisely controls the direction and timing of drug flow, ensuring the safety and accuracy of the loading process. The one-way valve 8 works in conjunction with the piston component 403, making the drug filling process smoother and more stable, not only increasing the loading speed but also significantly enhancing the consistency of the dosage for each loading, thereby greatly improving overall loading efficiency. The drive component 2 automatically adjusts the speed and stroke of the piston component 4, flexibly adapting to the needs of different specifications and types of products, reducing manual intervention, improving production continuity, and significantly enhancing overall production efficiency and loading accuracy.

[0030] In one embodiment, the drive assembly 2 includes a fixed housing 201 disposed on one side of the top of the worktable 1. A threaded rod 202 is disposed inside the fixed housing 201, and a drive plate 203 is disposed on the outer circumference of the threaded rod 202. The drive assembly 2 also includes a drive motor 204 disposed on one side of the fixed housing 201, and the output shaft of the drive motor 204 passes through one side of the fixed housing 201 and is connected to the threaded rod 202, thereby automatically adjusting the speed and stroke of the piston assembly 4 to flexibly adapt to the needs of different specifications and types of products.

[0031] In one embodiment, the piston assembly 4 includes a fixed rod 401 disposed at the top of the support frame 3, a connecting rod 402 passing through the interior of the fixed rod 401, one end of the connecting rod 402 being connected to the drive plate 203, and a piston component 403 disposed at the other end of the connecting rod 402, with a sealing groove 404 formed on the outer circumference of the piston component 403, thereby improving the overall production efficiency and loading accuracy of the loading machine.

[0032] In one embodiment, the one-way valve 8 includes a valve ring 801 disposed in the middle of the storage tube 7. A limit rod 802 is disposed inside the valve ring 801. The limit rod 802 cooperates with the valve ring 801 through a compression spring 803, thereby enabling precise control of the direction and timing of drug flow and ensuring the safety and accuracy of the drug loading process.

[0033] In one embodiment, the adjustment component 9 includes a fixed plate 901 disposed at the bottom of the storage tube 7. The bottom end of the fixed plate 901 is provided with an arc-shaped groove 902 and a moving groove 903. The fixed plate 901 is provided with a moving plate 904 inside.

[0034] The working principle of the adjusting component 9 is as follows: The operator operates the actuating plate 908, and through the cooperation between the actuating plate 908, the actuating groove 903, and the sliding column 906, the sliding plate 907 is moved inward or outward, thereby accurately controlling the flow rate of the drug in the storage tube 7. After adjusting to the required flow rate, the insert rod 909 is inserted into the corresponding limiting hole 912 to fix the position of the actuating plate 908, preventing it from moving accidentally during operation and ensuring a stable drug flow rate.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] In practical application, the staff connects the drug pipeline to the top of storage tube 2 7 to ensure that the drug can be smoothly delivered into storage tube 2 7. The controller starts the drive motor 204, which drives the threaded rod 202 to rotate, causing the drive plate 203 to move. This pushes the connecting rod 402 to slide axially within the fixed rod 401. The movement of the connecting rod 402 causes the piston 403 to move, pushing the drug from storage tube 2 7 into storage tube 1 6. When the amount of drug in storage tube 1 6 and storage tube 2 7 reaches the preset value, the drive motor 204 is started again to drive... Plate 203 drives connecting rod 402 to move in the opposite direction. Combined with the thrust of piston 403 and the gravity of the drug itself, pressure is applied to check valve 8. Compression spring 803 in check valve 8 extends under pressure, causing limit rod 802 to move downward. Valve ring 801 opens, and the drug flows through valve ring 801 to the bottom of storage pipe 7, completing the drug loading process and ensuring stable and controllable drug flow. In addition, the working principle of adjusting component 9 is as described above. Operators can accurately control the dosage of each loading, improving the stability of product quality.

[0037] In summary, by utilizing the above-mentioned technical solution of this utility model, and by setting the adjustment component 9, precise control of the dosage for each loading can be achieved, ensuring a high degree of consistency in the drug content of each product, thereby significantly improving the consistency of product quality. Furthermore, the adjustment component 9 not only provides the loading machine with sufficient flexibility to adapt to the needs of different specifications and types of product lines, but also effectively reduces drug waste, thereby lowering raw material costs. By setting the one-way valve 8, the direction and timing of drug flow can be precisely controlled, ensuring the safety and accuracy of the loading process. The one-way valve 8 works in conjunction with the piston component 403, making the drug filling process smoother and more stable, not only increasing the loading speed but also significantly enhancing the consistency of the dosage for each loading, thus greatly improving the overall loading efficiency. By setting the drive component 2, the speed and stroke of the piston component 4 can be automatically adjusted, flexibly adapting to the needs of different specifications and types of products, not only reducing manual intervention and improving production continuity, but also significantly improving overall production efficiency and loading accuracy.
