[0014] In the present application, after the medicines that need to be mixed and stirred are put into the dumbbell-shaped mixing box, the medicines will fall into the lower half of the dumbbell-shaped mixing box, and then the two feeding pipes can be closed.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1 Reference Figure 1-7 A stirring device, the stirring device body comprises a bottom plate 1, and a support frame 4 is firmly arranged above the bottom plate 1. The support frame 4 has a special structure, and a first support shaft 5 and a second support shaft 6 are rotatably connected to the inner walls of the top on both sides thereof, wherein one end of the second support shaft 6 cleverly extends to the outside of the support frame 4 for subsequent adjustment operations. A mounting ring 7 is firmly fixedly installed on the ends of the first support shaft 5 and the second support shaft 6 that are close to each other.

[0020] In order to achieve the mixing and stirring of the drugs, we designed a mixing mechanism. The core of the mechanism is a dumbbell-shaped mixing box 8, which runs through the mounting ring 7 and is closely connected to the inner wall of the mounting ring 7. The design of the dumbbell-shaped mixing box 8 is unique. A feed pipe 18 is fixedly installed on the inner wall of the top of one side and the inner wall of the bottom of one side, which is used for the delivery and removal of drugs. The feed pipe 18 is equipped with a sealing plug to ensure that the drugs will not leak during the stirring process. A driving motor 19 is also fixedly installed on the top of the dumbbell-shaped mixing box 8, and its output shaft extends deeply into the dumbbell-shaped mixing box 8 and is fixedly connected to the rotating shaft 20. Two stirring racks 22 are cleverly and symmetrically fixed on the rotating shaft 20. When the driving motor 19 is started, the rotating shaft 20 and the stirring rack 22 will be driven to rotate together, so as to efficiently mix and stir the drugs. At the same time, a mounting frame 21 is also fixedly installed in the dumbbell-shaped mixing box 8. The rotating shaft 20 runs through the mounting frame 21 and is rotatably connected to the inner wall of the mounting frame 21, which further ensures the stability of the stirring process.

[0021] In order to enhance the stirring effect, we also designed a ventilation mechanism. The mechanism is installed at the bottom of the dumbbell-shaped mixing box 8 and is closely connected to the inner wall of multiple ventilation holes. The core component of the ventilation mechanism includes a connecting shaft 23 fixedly installed at the bottom of the rotating shaft 20, and a gear assembly is cleverly connected to the connecting shaft 23. A mounting tube 25 is fixedly installed in the ventilation hole, and a support net 26 is fixed in the mounting tube 25 to prevent the drug from entering the ventilation mechanism. The bottom end of the mounting tube 25 extends to the bottom of the dumbbell-shaped mixing box 8 and is fixedly connected to a conical tube 27. An exhaust assembly is installed at the bottom of the conical tube 27, and the top of the exhaust assembly extends into the conical tube 27 and is closely connected to the gear assembly. When the connecting shaft 23 rotates with the rotating shaft 20, it will drive the gear assembly to move together, and then drive multiple exhaust assemblies to run through the transmission action of the gear assembly. The specific structure of the exhaust assembly includes a rotating ring 28 rotatably connected to the bottom of the conical tube 27, and an air suction blade 30 is fixedly installed in the rotating ring 28. When the rotating ring 28 receives the driving force of the gear assembly, it will rotate, thereby driving the suction blade 30 to rotate together. During the rotation of the suction blade 30, a strong suction force will be formed in the conical tube 27, and the external gas will be pumped into the conical tube 27, and then the gas will be blown into the dumbbell-shaped mixing box 8 through the mounting tube 25. In this way, while stirring the medicine, the wind can also be used to blow the medicine away, effectively preventing the medicine from accumulating during the stirring process.

[0022] In order to achieve the angle adjustment of the dumbbell-shaped mixing box 8, we designed an adjustment mechanism. The core component of the mechanism includes a stepper motor 9 fixedly mounted on the bottom inner wall of one side of the support frame 4. The output shaft of the stepper motor 9 passes through the bottom inner wall of one side of the support frame 4 and extends to the outside of the support frame 4. The output shaft of the stepper motor 9 and the second support shaft 6 are both fixedly sleeved with a synchronous wheel 10, and the same synchronous belt 11 is driven on the two synchronous wheels 10. When the stepper motor 9 is started, the corresponding synchronous wheel 10 will be driven to rotate. At this time, under the transmission cooperation of the synchronous belt 11 and the synchronous wheel 10 located on the second support shaft 6, the second support shaft 6 and the dumbbell-shaped mixing box 8 can be driven to rotate 180°. In this way, when the drugs are mixed and stirred, the drugs can be shaken longitudinally in the dumbbell-shaped mixing box 8, which helps to fully mix the drugs.

[0023] The present application can be used in the field of biopharmaceutical technology, and can also be used in other fields applicable to the present application.

[0024] Example 2 refer to Figure 3 , improved on the basis of Example 1: A novel biopharmaceutical stirring device, belonging to the field of biopharmaceutical technology, in order to ensure the stability of the stirring device during operation, we fixedly installed limiting tubes 2 at the four corners of the top of the bottom plate 1. The limiting rod 3 is slidably connected in the limiting tube 2, and the top of the limiting rod 3 extends to the top of the limiting tube 2 and is fixedly connected to the bottom of the support frame 4. Such a design enables the support frame 4 to slide longitudinally under the guidance of the limiting tube 2 and the limiting rod 3, thereby effectively avoiding the shaking problem during the stirring process.

[0025] In order to further improve the stirring effect, two vibration motors 31 are symmetrically fixedly installed on the top of the bottom plate 1. The top of the vibration motor 31 is fixedly connected to the bottom of the support frame 4. When the vibration motor 31 is started, the support frame 4 and the dumbbell-shaped mixing box 8 can be vibrated longitudinally. In this way, while stirring the medicine, the medicine can also be more fully mixed and stirred in the mixing mechanism by virtue of the vibration effect.

[0026] In addition, in order to ensure the stability of the dumbbell-shaped mixing box 8 during the rotation process, we also fixedly install the first mounting plate 13 and the second mounting plate 14 located above the first mounting plate 13 on one side of the support frame 4. The same limiting rod 15 is fixedly installed on the side where the first mounting plate 13 and the second mounting plate 14 are close to each other. The movable plate 12 is slidably sleeved on the limiting rod 15, and one side of the movable plate 12 is fixedly installed on one side of the synchronous belt 11. The bottom of the movable plate 12 and the top of the first mounting plate 13 are fixedly installed with the first magnet ring 16, and the two first magnet rings 16 can be attracted. At the same time, the top of the movable plate 12 and the bottom of the second mounting plate 14 are fixedly installed with the second magnet ring 17, and the two second magnet rings 17 can also be attracted. In this way, when the dumbbell-shaped mixing box 8 is rotated 180° in both positive and negative directions, the movable plate 12 can be driven to perform longitudinal reciprocating motion. When the driving motor 19 moves to the top, the two second magnet rings 17 will be attracted at this time, thereby limiting the synchronous belt 11 and the dumbbell-shaped mixing box 8. When the driving motor 19 moves downward, the two first magnet rings 16 will be attracted to each other, which can also achieve the limiting effect on the dumbbell-shaped mixing box 8.

[0027] However, as is well known to those skilled in the art, the working principles and wiring methods of the stepper motor 9, drive motor 19 and vibration motor 31 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0028] The above description is only a preferred specific implementation manner of the present invention, but 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 scheme and inventive concept 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.
