Description

Technical Field

[0001] The utility model relates to a mixing and stirring device for injection production, belonging to the technical field of injection production. Background Art

[0002] Injections refer to sterile solutions (including emulsions and suspensions) made of drugs for injection into the body, as well as sterile powders or concentrated solutions for preparation into solutions or suspensions before clinical use. Injections act quickly and reliably, are not affected by pH, enzymes, food, etc., have no first-pass effect, can exert systemic or localized effects, and are suitable for patients who are not suitable for oral medication or cannot take oral medication. However, the development and production process of injections is complicated, and the safety and body adaptability are poor, and the cost is relatively high.

[0003] For example, CN219149999U discloses a mixing and stirring device for injection production, in which a plurality of arc-shaped sealing blocks are synchronously driven by a collar, a support rod and a mounting frame, so that the tooth groove on one side of the arc-shaped sealing block drives the corresponding arc-shaped tooth block to rotate, and then the arc-shaped tooth block can drive the sealing plate to open and close in the particle hopper through the connecting block, thereby preventing the cavity in the particle hopper from being exposed to the external environment for a long time. However, the granular auxiliary materials need to be melted and mixed in the preparation liquid when entering the tank body for stirring, and the efficiency is insufficient during the mixing and stirring process.

[0023] Example 1: Please refer to Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] A mixing and stirring device for injection production comprises a tank body 1, a discharge pipe 2 is arranged below the tank body 1, a plurality of feed pipes 3 are arranged on one side above the tank body 1, a pad 4 is arranged at the center above the tank body 1 adjacent to one side of the feed pipe 3, a plurality of electric push rods 5 are arranged above the pad 4, a transmission shaft 6 is connected through the center of the pad 4 adjacent to one side of the electric push rod 5, the transmission shaft 6 passes through the inside of a support plate 7 above and is connected to the output end of a reducer 8, a crushing tank 9 is arranged on one side of the support plate 7, a material guide pipe 1 10 is arranged at the bottom of the crushing tank 9, a material guide pipe 2 11 is connected to one side above the crushing tank 9, and a barrel 12 is connected above the material guide pipe 11.

[0025] Specifically, four electric push rods 5 are provided on the pad 4 and are evenly arranged around the pad 4. The transmission shaft 6 is rotatably connected inside the pad 4 and the support plate 7. The bottom of the transmission shaft 6 extends to the inside of the tank body 1. A plurality of stirring blades 13 are provided outside the transmission shaft 6. A positioning rod 14 is provided at the lower part of the inside of the tank body 1. The positioning rod 14 is embedded in the outside of the transmission shaft 6. A slide groove is provided inside the transmission shaft 6 to accommodate the positioning rod 14. The transmission shaft 6 is slidably connected inside the positioning rod 14. The electric push rod 5 can drive the reducer 8, the transmission shaft 6, and the stirring blades 13 to move up and down, so that the stirring position depth of the stirring blades 13 in the tank body 1 can be adjusted, so that the liquid in the tank body 1 can be more uniform during stirring.

[0026] Specifically, the bottom of the material guide tube 10 extends to the inside of the tank body 1, a servo motor 15 is provided at the center above the crushing tank 9, and a crushing roller 16 is connected to the output end of the servo motor 15. A plurality of crushing teeth 17 are provided around the outside of the crushing roller 16, and a plurality of crushing teeth 2 18 are provided around the inside of the crushing tank 9 on one side adjacent to the crushing roller 16. When the crushing roller 16 rotates, the granular auxiliary material can be cut, squeezed and crushed by the crushing teeth 17 and the crushing teeth 2 18, thereby reducing the volume of the granular auxiliary material, thereby increasing the melting speed of the granular auxiliary material in the preparation liquid, and improving the stirring and mixing efficiency of the preparation liquid.

[0028] The working principle of the utility model is as follows: when in use, after opening the sealing cover 19, the granular auxiliary material is put into the barrel 12, and the auxiliary material enters the crushing tank 9 through the barrel 12 and the guide tube 11. When the servo motor 15 is running, the servo motor 15 can drive the crushing roller 16 to rotate. When the crushing roller 16 rotates, it can drive the crushing teeth 17 to rotate, so that the crushing teeth 17 and the crushing teeth 18 cut and extrude the auxiliary material, thereby grinding the granular auxiliary material and reducing the volume of the auxiliary material. The crushed auxiliary material can enter the interior of the tank body 1 through the guide tube 10. When the reducer 8 is running, the reducer 8 can drive the transmission shaft 6 and the stirring blades 13 to rotate, so that the stirring blades 13 can stir and mix the prepared liquid. During stirring, the electric push rod 5 can drive the support plate 7 to move up and down, thereby driving the reducer 8, the transmission shaft 6 and the stirring blades 13 to move up and down, so that the stirring blades 13 can stir at different depths in the prepared liquid, so that the prepared liquid can be more uniform during mixing and stirring.
