Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a mixing device for tablet production. Background Art

[0002] Mixing equipment for tablet production is an indispensable and important tool in the pharmaceutical process. Its main function is to evenly mix raw materials or medicines of different properties to ensure the quality and stability of tablets. This type of equipment usually adopts advanced mixing technology, such as stirring, drum or flying type, to ensure that the raw materials are fully stirred and mixed inside the equipment;

[0003] For example, a double-cone mixer disclosed in announcement number CN204768456U, when the speed sensor detects that the driving motor stops, the controller controls the locking mechanism to lock the rotating shaft, thereby maintaining the mixing drum at a specific position to meet the discharge requirements. However, the existing driving motor has a self-locking function and can control the stop angle of the mixing drum. In addition, like the traditional double-cone mixing equipment, the application places the material into the mixing drum and then rotates the mixing drum to mix the material. However, when the material is mixed by the mixing drum, the rotation of the mixing drum makes the materials contact and collide with each other in the mixing drum. However, this mixing method will increase the failure of uniform mixing of the material, thereby reducing the material mixing efficiency. Utility Model Content
