[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1-6 The pharmaceutical cold stirring mechanism and stirring device shown can realize the cold stirring of pharmaceutical powder, uniformly mix the various components in the pharmaceutical powder and discharge it. Cold stirring can prevent the degradation of heat-sensitive components, ensure that the components in the pharmaceutical powder remain stable, and the low temperature environment helps to reduce the growth of microorganisms and the occurrence of chemical reactions in the pharmaceutical powder, thereby extending the shelf life of the pharmaceutical powder and improving the safety and efficacy of the medicine.

[0021] refer to Figure 1 As shown, the stirring device includes a stirring hopper 2, which is installed above the processing platform 1. The stirring hopper 2 has an opening at the top, and a cover 3 is installed at the opening. A suction mechanism 4 is provided on one side. A conveyor line 5 is installed on the processing platform 1. The conveyor line 5 is used to transport bottles 6. The stirring hopper 2 stores medicine powder. After being stirred in the stirring hopper 2, the medicine powder is sucked into the suction mechanism 4 and filled into the bottles 6 from the bottom of the suction mechanism 4. After filling, the conveyor line 5 transports the bottles 6 away.

[0022] refer to Figure 2 As shown, a spiral stirring groove 7 is provided on the inner wall of the stirring bucket 2. The spiral stirring groove 7 is distributed in a spiral shape. When the powder is sucked out by the suction mechanism 4, it passes through the spiral stirring groove 7, thus achieving a certain degree of stirring and mixing.

[0023] refer to Figure 3As shown, the suction mechanism 4 includes a baffle 8, a suction box 9, a suction cylinder 10, a suction pipe 11, and a filling area 12. There are two baffles 8, both of which are fixedly installed on the mixing hopper 2. The suction box 9 is installed between the two baffles 8. The suction cylinder 10 is located at the upper end of the suction box 9, and one end of the suction cylinder 10 is connected to the interior of the mixing hopper 2. The other end of the suction cylinder 10 is connected to the suction pipe 11, which is connected to the suction box 9. The filling area 12 is located below the suction box 9 and is correspondingly located above the conveyor line 5.

[0024] refer to Figures 4 to 6 As shown, a first pipe 14 and a second pipe 15 are arranged inside the suction box 9. The lower end of the second pipe 15 passes through the bottom of the suction box 9 and corresponds to the position of the filling area 12. The upper end of the first pipe 14 is connected to the suction pipe 11. A power chamber 17 is also arranged inside the suction box 9, and a suction pump 18 is installed in the power chamber 17. An inclined surface 19 is arranged above the end of the first pipe 14 near the second pipe 15. Multiple suction holes 20 are arranged on the inclined surface 19, and the suction holes 20 penetrate both the upper and lower surfaces of the inclined surface 19. 0 corresponds to the air inlet of the suction pump 18. When the suction pump 18 is started, it generates suction. Under the action of suction, the powder in the stirring hopper 2 passes through the spiral stirring tank 7, the suction cylinder 10, and the suction pipe 11 in sequence and is then sucked into the first pipe 14. Due to the inertia of the powder passing through the horizontal section of the first pipe 14, the powder will fall into the second pipe 15 and be discharged through the bottom of the second pipe 15 and filled into the bottle 6. This ensures that the powder does not come into contact with the heat-generating element throughout the process. The powder is self-stirred and mixed during the transportation process, achieving the purpose of cold stirring.

[0025] In actual use, filter cotton is attached to the surface of the inclined surface 19 to further prevent the powder from entering the power chamber 17.

[0026] Furthermore, a water chamber 13 is provided in the suction box 9. The water chamber 13 surrounds the outside of the first pipe 14 and the second pipe 15. The water chamber 13 stores cold water. When the powder passes through the first pipe 14 and the second pipe 15, heat exchange occurs, ensuring a low-temperature processing environment for the powder.

[0027] On the side of the suction box 9, there is a first pair of interfaces 16 and a second pair of interfaces 21. A circulating water pump, a water tank and a chiller are connected to the first pair of interfaces 16 and the second pair of interfaces 21 to form a circulating water inlet and outlet system, which is a common existing technology. Generally, the circulating water pump is connected to the first pair of interfaces 16, the circulating water pump is connected to the water tank, the water tank is connected to the chiller, and the chiller is connected to the second pair of interfaces 21. The circulating water pump delivers the cold water stored in the water tank into the water chamber 13. Then, the water in the water chamber 13 that has undergone heat exchange enters the chiller for cooling through the second pair of interfaces 21. The cooled water is then delivered back into the water tank for recycling.

[0028] In summary, the cold stirring method in this invention can effectively prevent the degradation of heat-sensitive components in the powder during the mixing process, ensuring the chemical stability and efficacy of the powder. The low-temperature environment helps reduce the growth of microorganisms and the occurrence of chemical reactions, thereby extending the shelf life of the powder and improving the safety and effectiveness of the medicine.
