AI Technical Summary
When traditional mixing devices are used to mix pharmaceutical excipients, some of the raw materials sink to the bottom and are difficult to mix thoroughly with the raw materials on the top layer, resulting in insufficient mixing effect.
A mixing device including a support, a mounting frame, a mixing tank, and a mixing roller is designed. The mixing roller is driven to rotate by a first driving component, and the mounting frame is driven to flip by a second driving component. Combined with the design of a scraper and a hammer, the device can achieve comprehensive scraping and mixing of the inner wall of the mixing tank, thereby enhancing the mixing effect.
It improves the mixing effect of pharmaceutical excipients, ensures thorough mixing of various raw materials, and reduces waste.

The pivot of the mounting frame (2) is horizontal. A mixing tank (3) for filling auxiliary materials is mounted on the mounting frame (2). A stirring roller (4) is coaxially rotatably mounted inside the mixing tank (3). A first driving member (5) for driving the mounting frame (2) to rotate is provided on the bracket (1). A second driving member (6) for driving the stirring roller (4) to rotate is provided on the mixing tank (3).
2. The stirring device for producing pharmaceutical excipients according to claim 1, characterized in that: The stirring roller (4) includes a rotating rod (41), a sleeve (42) and two stirring frames (43).

The two stirring frames (43) are arranged on the outer wall of the sleeve (42). The sleeve (42) is coaxially slidably connected to the outside of the rotating rod (41) so that the two sides of the stirring frames (43) can move and contact the inner top wall and inner bottom wall of the stirring tank (3) as the stirring tank (3) flips.
3. The stirring device for producing pharmaceutical excipients according to claim 2, characterized in that: The stirring frame (43) includes a scraper rod (431), two first stirring rods (432) and a plurality of second stirring rods (433) disposed on the outer wall of the sleeve (42). The two first stirring rods (432) are respectively disposed radially along the outer wall of both ends of the sleeve (42). The plurality of second stirring rods (433) are parallel to the first stirring rods (432) and disposed between the two first stirring rods (432). The two first stirring rods (432) are respectively in movable contact with the inner top wall and inner bottom wall of the stirring tank (3). The scraper rod (431) is slidably connected to the second stirring rod (433) along the length direction of the second stirring rod (433). The plurality of second stirring rods (433) are provided with a slide (4331) for the scraper rod (431) to slide. The stirring tank (3) is provided with a third driving member (7) for driving the scraper rod (431) to move and movably contact the inner wall of the stirring tank (3).
4. The stirring device for producing pharmaceutical excipients according to claim 3, characterized in that: The third driving component (7) includes a rotary joint (71) and an air pipe (72). The rotary joint (71) is rotatably connected to one end of the mixing tank (3). An air chamber (411) communicating with the rotary joint (71) is opened in the rotating rod (41). An air hole (8) for communicating with the air chamber (411) and the slide (4331) is opened on the side wall of the sleeve (42) and the rotating rod (41). One end of the air pipe (72) is connected to the rotary joint (71), and the other end of the air pipe (72) is connected to an industrial fan (73) for air intake and exhaust.
5. The stirring device for producing pharmaceutical excipients according to claim 3, characterized in that: The part of the scraper rod (431) that enters the slide (4331) is provided with a sealing plug (9).
6. The stirring device for producing pharmaceutical excipients according to claim 1, characterized in that: A hammer (10) for reciprocatingly striking the mixing tank (3) is vertically slidably mounted on the support (1), and a fourth driving member (20) for driving the hammer (10) to move is provided on the support (1).
