Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical technology, and in particular to a multifunctional pharmaceutical liquid mixing device. Background Technology

[0002] In the pharmaceutical manufacturing process, drug-liquid mixing is a crucial step, and its effectiveness directly affects drug quality and production efficiency. However, existing pharmaceutical mixing equipment has several shortcomings:

[0003] Poor mixing effect: Traditional mixing devices mostly use a single stirring structure, which makes it difficult to ensure uniform mixing when mixing drug solutions with different properties and proportions. For example, some complex drug solutions contain multiple active substances and excipients, and conventional stirring cannot fully integrate them, which may lead to unstable quality of different batches of drugs, affect the consistency of efficacy, and increase the risk of drug substandard products.

[0004] Insufficient ease of operation: The equipment's operation design is not user-friendly, causing inconvenience in feeding, discharging, and cleaning and maintenance. For example, the feeding port design is unreasonable, making material feeding difficult and prone to spillage; residual medicine is easily left at the discharge port, and incomplete cleaning may cause cross-contamination; the complex internal structure of the equipment makes some parts difficult to disassemble and clean, and long-term use will accumulate dirt, affecting the quality and safety of medicines.

[0005] In conclusion, it is essential to develop a multifunctional pharmaceutical liquid mixing device that can solve the above problems, which is of great significance for improving the production level and drug quality of the pharmaceutical industry. Utility Model Content

[0021] like Figure 1 and Figure 2As shown, it also includes a first pin 21, a first limiting block 22, a spring 23, a hollow cavity 24, support legs 25, a slot 26, a second limiting block 27, a second pin 28, a third limiting block 29, a rack 30, a gear mounting rod 31, a second motor 32, a broken tooth 33, a second pulley 34, and a second belt 35; the first mixing chamber 1 is disposed in the hollow cavity 24; the upper and lower ends of the right side of the first mixing chamber 1 are fixedly connected to the first pin 21, the first pin 21 is slidably connected in the hollow cavity 24, and the right end of the first pin 21 is fixedly connected to the first limiting block 22; the outer surface of the first pin 21 located inside the hollow cavity 24 is covered and connected to the spring 23; several support legs 25 are fixedly connected around the lower surface of the hollow cavity 24; the lower end of the left side of the first mixing chamber 1 is fixedly connected to the second pin 28.

[0022] The rack 30 and the broken tooth 33 are coated with grease; the first gear 15 and the second gear 16 are coated with grease; the traveling wheel 2 is a universal wheel with a braking device; and the feeding port 3 is flared.

[0023] The usage state of this utility model is as follows: (1) Feeding process: The operator pours the medicine to be mixed into the funnel-shaped feeding port 3. The funnel-shaped design increases the feeding area, which makes it easier to add the medicine quickly and accurately, and effectively reduces the spillage and waste of the medicine. The medicine poured into the feeding port 3 flows into the second mixing chamber 7 along the feed inlet 5, preparing for the mixing operation.

[0024] (2) Mixing and stirring operation: The operator turns on the power to the first motor 12, and the first motor 12 starts, and its output end drives the second rotating shaft 19 to rotate. The first pulley 13 at the top of the second rotating shaft 19 rotates accordingly, and drives the first rotating shaft 18 to rotate synchronously through the first belt 14. The stirring paddle 20 installed on the first rotating shaft 18 rotates in the second mixing chamber 7 to axially stir the liquid medicine entering the second mixing chamber 7.

[0025] Meanwhile, the first gear 15 on the second rotating shaft 19 rotates with the second rotating shaft 19 and meshes with the second gears 16 at the upper and lower ends of the second mixing chamber 7. Under the transmission action of the gears, the second mixing chamber 7 is supported by the steering wheel (8) and makes a circular motion in the circular groove 6 preset on the bottom surface of the first mixing chamber 1, so as to realize the circumferential stirring of the medicine liquid.

[0026] Under the combined action of axial and circumferential stirring, liquids of different properties and proportions are rapidly and thoroughly mixed in the second mixing chamber 7, ensuring that the drug components are uniform and consistent.

[0027] When the second motor 32 is started, the second pulley 34 at the output end of the second motor 32 rotates, and drives the second pulley 34 on the side of the broken tooth 33 through the second belt 35, so that the broken tooth 33 rotates on the gear mounting rod 31.

[0028] Because the broken tooth 33 meshes with the rack 30, the rack 30 slides as the broken tooth 33 rotates. The rack 30 drives the second pin 28, which is fixedly connected to it, and the first mixing chamber 1 to move within the hollow cavity 24. At the same time, under the leftward movement of the spring 23, the first mixing chamber 1 achieves left-right reciprocating motion, further realizing the effect of mixing the medicine.

[0029] (3) Discharge process: After the medicine is mixed, the operator opens the discharge valve 10, and the mixed medicine flows out through the discharge pipe 9 under the action of gravity. The discharge valve 10 is located in the circular hole 11, and the slot 26 on the bottom surface of the hollow cavity 24 is below the discharge valve 10. With the cooperation of these components, the medicine is discharged smoothly, avoiding residue and ensuring the efficiency and cleanliness of the discharge process.
