[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The utility model provides Figures 1-5A drying device for pharmaceutical processing as shown, includes a drying box body 1. A top cover 2 is snap-fitted and installed on the top of the drying box body 1. A drying cylinder 3 is movably installed inside the drying box body 1. An electric motor 4 is fixedly installed on the inner wall of the motor slot at the bottom of the drying box body 1. The output shaft of the electric motor 4 is drivingly connected to a driving shaft 5. And the driving shaft 5 is drivingly connected to a first linkage shaft 6. The first linkage shaft 6 is rotatably connected to the bottom of the drying cylinder 3 through a bearing. A first stirring blade 9 is fixedly connected to the outer ring of the first linkage shaft 6. A second linkage shaft 10 is rotatably connected to the inside of the first stirring blade 9 through a bearing. And a second stirring blade 11 is fixedly sleeved on the outer ring of the second linkage shaft 10. A cavity 12 is arranged at a position above the drying cylinder 3. And a toothed ring 14 is fixedly connected to the inner wall of the cavity 12. And the toothed ring 14 is meshed with a gear 13 sleeved on the outer ring of the second linkage shaft 10. The second linkage shaft 10 passes through the inside of a movable channel 15. The movable channel 15 is communicated with the cavity 12. And a brush 16 is fixedly connected to the inner wall of the movable channel 15. A feeding port 17 is arranged on the side of the drying cylinder 3. And a discharge port 18 is opened at the bottom of the drying cylinder 3. And a baffle 19 is installed inside the discharge port 18 to facilitate the feeding and discharging of the drying cylinder 3.

[0025] The driving shaft 5 is located inside the drying box body 1. And a columnar fitting groove 8 with a diameter equal to that of the first linkage shaft 6 is arranged at the top of the driving shaft 5. And a plurality of semi-columnar protrusions 7 distributed at equal angles in a ring shape are fixedly connected inside the fitting groove 8. The protrusions 7 are matched with the engaging grooves arranged at the bottom of the first linkage shaft 6. When the drying cylinder 3 is installed inside the drying box body 1, the matching installation of the first linkage shaft 6 and the driving shaft 5 ensures that the driving shaft 5 drives the first linkage shaft 6 to rotate synchronously.

[0026] The inside of the first stirring blade 9 is hollow. And the first stirring blade 9 is rotatably connected to the second stirring blade 11 so that the synchronous rotation of the first stirring blade 9 and the second stirring blade 11 is not affected.

[0027] Two second linkage shafts 10 are provided in number. And the two second linkage shafts 10 are symmetrically distributed inside the first stirring blade 9 with the first linkage shaft 6 as the axis of symmetry. And a gap is left between the top of the second linkage shaft 10 and the top wall of the cavity 12.

[0028] The movable channel 15 is semi-circular. And two movable channels 15 are provided in number. The two movable channels 15 are symmetrically distributed with the first linkage shaft 6 as the axis of symmetry. And the two movable channels 15 are not communicated with each other so that when the first stirring blade 9 rotates to drive the second linkage shaft 10 to perform circular motion, the movement of the second linkage shaft 10 is not hindered.

[0029] Brush 16s are fixedly connected to both inner walls of the movable channel 15. The second linkage shaft 10 passes through the gap between the two brush 16s. This avoids some impurities from entering the inside of the cavity 12 during the drying operation of the medicinal materials and keeps the inside of the cavity 12 clean.

[0030] Working principle: When using a drying device for pharmaceutical processing, first start the motor 4 to rotate forward and reverse to drive the linkage shaft 6 connected to the output shaft of the motor 4 to rotate forward and reverse (the forward and reverse rotation angles of the motor 4 are 0-170 degrees), so that the stirring blade 9 sleeved on the outer ring of the linkage shaft 6 rotates to stir the medicinal materials inside the drying cylinder 3. The internal rotation of the stirring blade 9 is connected to two symmetrically arranged linkage shafts 2 10. At the same time, the rotation of the stirring blade 9 drives the linkage shaft 2 10 to perform circular motion synchronously. The gear 13 sleeved on the outer ring of the linkage shaft 2 10 is engaged with the gear ring 14 in the moving state to realize the self-rotation of the linkage shaft 2 10, causing the stirring blade 2 11 to rotate. The stirring of the two groups of stirring blades improves the overall drying efficiency. At the same time, the top cover 2 can be opened later to lift out the drying cylinder 3, and then a new drying cylinder 3 containing the medicinal materials to be processed can be directly installed. It is only necessary to match the linkage shaft 6 at the bottom of the new drying cylinder 3 with the interlocking groove 8 at the top of the drive shaft 5, thereby ensuring the feeding efficiency and improving the overall production rate.
