Description

Technical Field

[0001] This utility model relates to the field of active pharmaceutical ingredient (API) packaging technology, specifically to a closed packaging device for APIs. Background Technology

[0002] In the production of active pharmaceutical ingredients (APIs), dispensing is a critical step, requiring the precise distribution of large quantities of APIs into containers according to preset dosages. While existing closed-system dispensing equipment can reduce drug leakage through its sealed cavity, in actual operation, a small amount of API often remains on the inner wall of the dispensing head after each dispensing operation. These residues gradually drip off under gravity, and since traditional equipment lacks a shielding structure below the dispensing head, the dripping API can easily contaminate the dispensing production line. This not only wastes raw materials but may also cause production line contamination, increasing subsequent cleaning costs and quality risks. Utility Model Content

[0003] In view of the problems existing in the closed-loop dispensing equipment for active pharmaceutical ingredients, this utility model is proposed.

[0004] Therefore, the purpose of this invention is to provide a closed-loop dispensing device for active pharmaceutical ingredients, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A closed-loop dispensing device for active pharmaceutical ingredients (APIs) includes an API tank and a pump. The pump is fixedly mounted on the lower side of the API tank, and its inlet extends into the interior of the API tank. A dispenser is located below the pump, and multiple dispensing heads are located below the dispenser. A connecting pipe is fixedly connected to the outlet of the pump, and a fixing pipe is fixedly mounted to the inlet of the dispenser. The connecting pipe is inserted into the fixing pipe. A connecting mechanism is provided between the dispenser and the API tank, and the dispenser and the API tank are connected by a limiting connection through the connecting mechanism.

The pump 2 is fixedly installed on the lower side of the API tank 1. A feed inlet is provided on the rear top side of the API tank 1 to facilitate the replenishment of APIs into the API tank 1. The feed inlet of the pump 2 extends into the interior of the API tank 1. A dispenser 3 is installed below the pump 2, and multiple dispensing heads 4 are installed below the dispenser 3. A connecting pipe 13 is fixedly connected to the discharge port of the pump 2. A fixing pipe 14 is fixedly installed at the inlet of the dispenser 3. The connecting pipe 13 is inserted into the fixing pipe 14. Sealing rings are provided on the inner wall of the fixing pipe 14 and the outer wall of the connecting pipe 13 to improve the sealing between the fixing pipe 14 and the connecting pipe 13. A connecting mechanism is provided between the dispenser 3 and the API tank 1, and the dispenser 3 and the API tank 1 are connected by the connecting mechanism. A receiving shell 8 is provided below the dispenser 3, and a transmission mechanism for rotating the receiving shell 8 is provided on one side of the API tank 1.

[0020] Reference Figure 1-3 The connecting mechanism includes a fixing block 10 and a stop block 12. The two fixing blocks 10 are fixedly installed on both sides of the lower surface of the raw material tank 1. A T-shaped groove is opened on the front side of the fixing block 10. The stop block 12 is abutted against the inner wall of the T-shaped groove. A connecting rod 11 is fixedly installed on the lower side of the stop block 12. A rotating rod 18 is fixedly installed at the lower end of the connecting rod 11. One end of the rotating rod 18 is rotatably connected to the outer wall of the fixing pipe 14. Limiting blocks 15 are fixedly installed on both sides of the drug pump 2. An insert rod 16 is movably sleeved inside the limiting block 15. An insertion hole is opened on the rod wall of the rotating rod 18. The lower end of the insert rod 16 is inserted into the insertion hole. A reset block 17 is fixedly sleeved on the middle end of the insert rod 16. A spring 20 is fixedly connected between the reset block 17 and the limiting block 15 to facilitate the insertion rod 16 to move down and reset. A pull block 19 is fixedly installed on the upper end of the insert rod 16 to facilitate the pulling of the insert rod 16.

[0021] Reference Figure 1-3The transmission mechanism includes a transmission rod 6 and a motor 9. A first connecting block 5 is fixedly installed on the outer wall of the raw material tank 1, and a second connecting block 7 is fixedly installed on the outer wall of the receiving shell 8. The transmission rod 6 is fixedly installed on the upper side of the second connecting block 7, and the upper end of the transmission rod 6 is rotatably connected to the first connecting block 5. The motor 9 is fixedly installed on the upper surface of the first connecting block 5, and the output end of the motor 9 is fixedly connected to one end of the transmission rod 6.

[0022] In this invention, during use, the pump 2 is started, and its inlet draws raw materials from the raw material tank 1. The raw materials are then transported through the outlet connecting pipe 13 to the fixed pipe 14 of the dispenser 3. After entering the dispenser 3, the raw materials are distributed to multiple dispensing heads 4 below via the internal structure and dispensed into containers below according to a preset dosage. After a single dispensing operation, to prevent residual raw materials in the dispensing heads 4 from dripping and contaminating the production line, the motor 9 on one side of the raw material tank 1 is started. The output of the motor 9 drives the transmission rod 6 to rotate. Since the upper end of the transmission rod 6 is rotatably connected to the first connecting block 5 and the lower end is fixed to the second connecting block 7, the rotation of the transmission rod 6 will drive the second connecting block 7 and the receiving shell 8 fixed thereto to rotate synchronously until the receiving shell 8 moves directly below the dispensing head 4, blocking it. Residual raw materials dripping from the receiving shell 8 will fall directly into the receiving shell 8, preventing contamination of the dispensing production line. If further adjustments are needed... To adapt to different packaging requirements, a different type of dispenser 3 is used. Pulling the pull block 19 upwards causes the insertion rod 16 to move upwards along the limiting block 15. The lower end of the insertion rod 16 disengages from the insertion hole of the rotating rod 18, while the reset block 17 compresses the spring 20. Then, using the rotational connection point between the rotating rod 18 and the fixed tube 14 as an axis, the connecting rod 11 rotates. The connecting rod 11 causes the stop block 12 to disengage from the T-slot of the fixed block 10, releasing the dispenser 3 from the original... Limit the material tank 1; then pull down the dispenser 3 to separate the fixed tube 14 from the connecting tube 13, and the old dispenser 3 can be removed; align the fixed tube 14 of the new dispenser 3 with the connecting tube 13 and insert it, rotate the connecting rod 11 in the opposite direction to make the stop block 12 re-enter the T-slot, release the pull block 19, the spring 20 releases its elastic force to push the reset block 17 and the insertion rod 16 down, the insertion rod 16 is inserted into the insertion hole of the rotating rod 18 to complete the limit, and the dispensing operation can continue.

[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
