Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, specifically a two-dimensional motion mixer for pharmaceutical production. Background Technology

[0002] In the pharmaceutical manufacturing industry, mixers, as core equipment on the drug production line, undertake the crucial task of uniformly mixing various raw materials, excipients, and other materials. Their mixing effect directly affects the quality stability and efficacy of the drugs. Taking tablet production as an example, if the active ingredient is not mixed uniformly with excipients such as fillers and binders, it may lead to excessive differences in drug content between different tablets, affecting clinical treatment efficacy. However, the traditional pharmaceutical mixers currently in widespread use have revealed many drawbacks in actual production. Most traditional mixers use unidirectional stirring blades or rotation, allowing materials to move only in a fixed plane or axis, forming limited convection and diffusion, making it difficult to achieve high standards of mixing uniformity. Studies have shown that some traditional mixers can only maintain a mixing uniformity of 85%-90% when processing multi-component materials, far below the stringent requirements for drug uniformity in modern pharmaceutical processes.

[0003] Furthermore, structural design flaws in traditional mixers have led to a series of subsequent problems. After mixing, materials easily adhere to the inner walls, corners, and gaps in the mixing components of the mixing drum. This is especially true for sticky or hygroscopic materials, where cleaning becomes exponentially more difficult. Even with manual disassembly and deep cleaning, it is difficult to completely remove residual materials. Residual materials from previous batches may cross-contaminate subsequent batches, violating Good Manufacturing Practices (GMP) and potentially posing serious medication safety hazards. Simultaneously, traditional mixers require manual assistance when unloading materials, consuming significant manpower and posing risks of spillage and contamination. In terms of equipment operation control, the lack of intelligent adjustment mechanisms makes it difficult to flexibly adjust mixing parameters according to material characteristics, severely hindering production efficiency. With the pharmaceutical industry's pursuit of zero-defect drug quality and the trend towards intelligent and efficient production, the development of a new pharmaceutical mixer with high-efficiency mixing performance, convenient cleaning functions, and automated operation is urgently needed.

An auxiliary fixing ring 9 is movably connected to the outer surface of the flipping shaft 8. A mixing tank 18 is located inside the auxiliary fixing ring 9. A movable groove 7 is opened inside the movable seat 4. A fixing shaft 10 is located inside the movable groove 7. A flipping block 11 is movably connected to the outer surface of the fixing shaft 10. An electric telescopic rod 12 is fixedly connected to the side of the flipping block 11. A connecting block 13 is connected to the other end of the electric telescopic rod 12. A connecting fixing ring 14 is movably connected to the outer side of the connecting block 13. Thus, by setting up the pouring unit, after the drug is prepared, the electric telescopic rod 12 is further activated, causing the electric telescopic rod 12 to push the connecting fixing ring 14. The connecting fixing ring 14 then drives the mixing tank 18, causing the mixing tank 18 to flip around the flipping shaft 8, thereby facilitating the pouring of the mixed drug solution.

[0025] Both the auxiliary fixing ring 9 and the connecting fixing ring 14 are equipped with limit ball bearings on their inner sides, which allows the mixing barrel 18 to rotate inside the auxiliary fixing ring 9 and the connecting fixing ring 14.

[0026] The mixing unit includes an electric telescopic rod 3, which is located inside the moving groove 2. A slide rod 5 is located inside the moving groove 2, and a buffer spring 6 is located on the outer surface of the slide rod 5. A moving seat 4 moves on the outer surface of the slide rod 5. A motor 15 is located inside the connecting fixing ring 14, and the output shaft of the motor 15 is connected to a transmission disc 16. A slide rail 17 is located on the outer surface of the mixing tank 18. By setting up the mixing unit, and then adding medicinal materials into the mixing tank 18, further activating the electric telescopic rod 3 causes the moving seat 4 to move on the outer surface of the slide rod 5. Further activating the motor 15 causes the transmission disc 16 to contact the slide rail 17, thereby causing the mixing tank 18 to move and further mix the materials.

[0027] The slide rail 17 has an external gear ring inside, and the outer surface of the transmission disc 16 is wound with a transmission gear that matches the external gear ring. When the transmission disc 16 rotates, the transmission gear on the outer surface of the transmission disc 16 meshes with the external gear ring, thereby causing the mixing drum 18 to rotate.

This effectively protects the motor 15 from external debris, dust and moisture, and ensures good heat dissipation during operation, thus ensuring stable and reliable operation of the motor 15.

[0032] Working principle: When preparing medicine, the medicinal materials are added to the mixing tank 18. The electric telescopic rod 3 is activated, causing the moving seat 4 to move on the slide rod 5. Simultaneously, the motor 15 is activated, driving the transmission disc 16 to contact the slide rail 17 on the outer surface of the mixing tank 18. Through the meshing of the transmission gear and the external gear ring, the mixing tank 18 rotates, achieving mixing of the medicinal materials. After the medicine preparation is completed, the electric telescopic rod 12 is activated to push the connecting fixing ring 14, causing the mixing tank 18 to rotate around the tilting shaft 8, pouring out the mixed liquid. Afterwards, the mixture is... Water from the water storage tank assembly 19 is transported through the transport pipe 20 to the spray pipe 21, and then sprayed out through the nozzle 22 to clean the inside of the mixing tank 18. The flow control valve on the transport pipe 20 can precisely control the water flow to adjust the rinsing force and water consumption. In addition, the auxiliary fixing ring 9 and the limiting ball bearings on the inner side of the connecting fixing ring 14 allow the mixing tank 18 to rotate within it. The sealing assembly 24 on the front of the mixing tank 18 prevents the medicinal materials from falling out during mixing. The stainless steel protective cover on the outside of the motor 15 is equipped with heat dissipation holes to ensure stable operation of the motor.
