[0002] In the field of pharmaceutical production, filling equipment is one of the key equipment to ensure the quality and safety of drugs. Traditional pharmaceutical filling equipment usually includes basic components such as filling chamber, stirring mechanism, filtering mechanism and discharge port. These devices realize the filling of drugs through mechanical stirring and gravity, and use filter screens or filter plates to perform preliminary filtration of impurities in drugs.

[0045] Furthermore, the adjustment mechanism of the present invention realizes the flexible adjustment of the position of the third discharge pipe 5 through the coordinated design of the turning handle 39 and the threaded rod 35, and has significant practicality and convenient operation. First, the mechanism drives the movement of the bracket 36 through the rotation of the threaded rod 35, so that the slide plate 9 can slide up and down freely, thereby accurately adjusting the position of the third discharge pipe 5. This design not only simplifies the operation process, but also improves the adaptability of the equipment. It can quickly adjust the height of the discharge pipe according to different drug filling requirements, ensure that the drugs enter the packaging container accurately, and avoid drug waste or pollution caused by improper position. Secondly, the adjustment mechanism has a compact structure and occupies a small space, which is easy to integrate into existing equipment, and no complex tools or additional power sources are required during the operation. The adjustment can be completed by manually rotating the turning handle 39, which significantly reduces the difficulty of operation and labor costs. In addition, the adjustment mechanism has high stability, and the close contact between the bracket 36 and the sterile cabin 1 ensures that the third discharge pipe 5 will not be displaced during the filling process, further improving the accuracy and reliability of the filling. This design is particularly suitable for high-precision drug filling scenarios, and can effectively improve production efficiency and product quality. Through the synergistic effect of the motor-driven rotating frame 11 and the through-tube 12, the uniform mixing and efficient filling of the drugs in the sterile cabin 1 are achieved, with significant mixing effect and filling accuracy. First, the rotating design of the rotating frame 11 allows the drugs to be fully stirred in the cabin, ensuring that the drug ingredients are evenly distributed, avoiding the problem of unstable drug quality caused by uneven mixing. Secondly, the through-tube 12 realizes the circulation of drugs in the through-tube through the cooperation of the guide rod 30, the arc-shaped inclined rod 20, the slide 21 and the tension spring 27, further improving the fluidity of the drugs, ensuring that the drugs can smoothly enter the packaging container during the filling process, and avoiding the problem of uneven filling caused by drug viscosity or precipitation. In addition, the filling mechanism has a high degree of automation, which reduces the intervention of manual operation, reduces operating errors, and improves filling efficiency and consistency. This design is particularly suitable for large-scale drug production environments, and can significantly improve production efficiency and product quality, while reducing drug waste and production costs. Through the design of the conical filter plate 13 and the telescopic rod 14, effective filtration of impurities in the drug is achieved, with significant filtering effect and equipment stability. First, the conical filter plate 13 is located at the bottom of the sterile cabin 1, which can intercept solid impurities in the drug, ensure that the drug discharged through the first discharge pipe 3 is clean and pollution-free, and improve the purity and safety of the drug. Secondly, the design of the telescopic rod 14 and the spring 15 enables the conical filter plate 13 to vibrate up and down to prevent the filter plate from being blocked, ensuring the durability of the filtering effect, extending the service life of the equipment, and reducing the maintenance frequency. In addition, the structure of the filtering mechanism is simple, easy to disassemble and clean, and further reduces the maintenance cost of the equipment.This design is particularly suitable for production environments with extremely high requirements for drug cleanliness, and can effectively improve drug quality and production efficiency, while reducing the product failure rate caused by impurity contamination. Through the synergistic effect of the angle scraper 17 and the fixed column 19, the impurities on the conical filter plate 13 are automatically cleaned, which has a significant cleaning effect and convenient equipment maintenance. First, the angle scraper 17 scrapes the surface of the conical filter plate 13 under the drive of the rotating frame 11 to remove impurities attached to the filter plate, avoid the problem of filter plate clogging, and ensure the durability of the filtering effect. Secondly, the design of the fixed column 19 and the telescopic rod 14 enables the conical filter plate 13 to vibrate up and down, further enhancing the cleaning effect, preventing impurities from accumulating, and improving the continuous working ability of the equipment. In addition, the automated operation of the cleaning mechanism reduces the frequency of manual cleaning, reduces the equipment maintenance cost, and ensures that the equipment can still maintain efficient filtering performance during long-term operation. This design is particularly suitable for continuous production of drug filling environments, which can significantly improve the working efficiency and stability of the equipment, while reducing production interruptions and drug waste caused by filter plate clogging.

[0046] Instructions for use: When it is necessary to mix the liquid medicine in the sterile cabin 1, first start the motor, the motor rotation drives the rotating frame 11 to rotate, so that the rotating frame 11 preliminarily stirs the liquid medicine in the sterile cabin 1, and at the same time, the rotating frame 11 rotates to drive the through pipe 12 to rotate, when the through pipe 12 rotates to a suitable position, the guide rod 30 contacts the arc-shaped inclined rod 20 and moves upward along the arc-shaped inclined rod 20, the guide rod 30 moves upward to make the slide 21 drive the fixed disk 28 to move upward, the fixed disk 28 moves upward through the retaining ring 29 to make the liquid medicine in the sterile cabin 1 enter the through pipe 12, and is located under the fixed disk 28, the slide 21 moves upward to make the tension spring 27 stretched and generate tension, and at the same time, the liquid medicine above the fixed disk 28 in the through pipe 12 is discharged from the first discharge port 2 2 is discharged, and the thrust of the discharged medicine liquid is enhanced through the cover plate 26. When the guide rod 30 is out of contact with the arc-shaped inclined rod 20, the tension spring 27 rebounds and resets to make the slide 21 drive the fixed plate 28 to move downward. Under the action of pressure, the retaining ring 29 drives the connecting frame 31 to move upward, so that the liquid hole 32 is opened, and then the liquid below the fixed plate 28 can easily pass through the liquid hole 32 to enter the top of the fixed plate 28. This reciprocating cycle makes the medicine liquid in the sterile cabin 1 more fully mixed, and then the conical filter plate 13 can filter the impurities, so that the medicine liquid discharged from the first discharge pipe 3 is cleaner, and the filtered residue is discharged through the second discharge pipe 4. At the same time, the rotating frame 11 rotates to drive the angle scraper 17 to rotate, so that the angle scraper 17 can filter the conical filter plate 13. The impurities on the conical filter plate 13 are initially cleaned. At the same time, when the angular scraper 17 rotates to contact one of the fixed columns 19, the fixed column 19 is forced to rotate clockwise along the inclined surface of the angular scraper 17, so that the other fixed column 19 squeezes the conical filter plate 13, and the conical filter plate 13 is moved downward by the telescopic rod 14, and the spring 15 is forced to shorten and generate elastic force. When the angular scraper 17 rotates to between the two fixed columns 19, the spring 15 rebounds and resets, driving the conical filter plate 13 to move upward and reset, and drives the fixed column 19 to rotate counterclockwise and reset, and then re-fits with the two fixed columns 19. Then the angular scraper 17 continues to rotate until it contacts the other fixed column 19, and the other fixed column 19 is forced to rotate counterclockwise along the inclined surface of the angular scraper 17 The cone filter plate 13 is pressed against the filter element 13 by the spring 15 and moves downward. When the angle scraper 17 rotates to a suitable position and disengages from the other fixing column 19, the spring 15 rebounds and resets, driving the cone filter plate 13 to move upward and reset, and driving the fixing column 19 to rotate clockwise and reset. This reciprocating cycle is repeated, so that the cone filter plate 13 vibrates up and down through the two fixing columns 19 and the angle scraper 17 to avoid blockage of the cone filter plate 13. When it is necessary to take out the liquid medicine after static stratification, first judge the stratification position of the liquid medicine after static stratification through the observation window 38, and then turn the handle 39. The rotation of the handle 39 drives the threaded rod 35 to rotate. The threaded rod 35 rotates through the third slide slot 34 to move the bracket 36 outward.Thereby, the bracket 36 is disengaged from the sterile cabin 1, and then the slide plate 9 is moved upward. The slide plate 9 is driven by the force to drive the third discharge pipe 5 to move upward along the first slide groove 8 until it moves to a suitable position, so that the separated liquid surface after static stratification is at the same horizontal line with the bottom inner wall of the third discharge pipe 5, and then the handle 39 is reversely rotated to make the threaded rod 35 drive the bracket 36 to move inward and contact and press with the sterile cabin 1 again, so that the position of the third discharge pipe 5 is adjusted and fixed, and then it is convenient to discharge the upper layer of liquid after stratification through the third discharge pipe 5, and then discharge the lower layer of liquid after stratification through the first discharge pipe 3, so as to avoid stratification of the mixed liquid after standing, and then discharge the stratified liquid from the bottom drainage hole. However, during the discharge process, the stratified liquid is easy to blend, thereby affecting the filling effect.

[0047] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
