[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a low-temperature drying device for traditional Chinese medicine tablets, which has the following beneficial effects:

[0014] The low-temperature drying device for this traditional Chinese medicine tablet uses a drive motor to rotate a drive gear, which in turn rotates a rotating shaft and a tilting plate via a driven gear, thus turning the tablets inside the container. Simultaneously, a servo motor can be activated to rotate a drive bevel gear, which in turn rotates a threaded rod. During rotation, the threaded rod causes two sliders to move relative to each other, which in turn moves a moving plate, rotating shaft, and tilting plate upwards via a connecting rod. Then, the servo motor rotates in the opposite direction, causing the threaded rod to rotate in the opposite direction. During rotation, the rotating rod drives two sliders to move in opposite directions, which in turn drives the moving plate, rotating shaft, and tilting plate to move downwards via the connecting rod. Then, the servo motor rotates forward again, and this cycle repeats, causing the tilting plate to move up and down. As the tilting plate rotates, it moves up and down to expand the tilting area, thus fully turning over the Chinese medicine slices in the container. This ensures that all the slices come into contact with the hot air, resulting in even heating and thorough drying, ultimately achieving a good drying effect. Attached Figure Description

[0021] A movable plate 11 is movably installed between the two support plates 2. A rotating shaft 12 is movably installed on the top of the movable plate 11, with one end penetrating through the drying tank 3 and extending into the placement tank 7. A first bearing is fixedly installed on the top of the movable plate 11. The rotating shaft 12 is rotatably connected to the top of the movable plate 11 through the first bearing. Three tilting plates 13 are fixedly installed on both the left and right sides of the rotating shaft 12, located inside the placement tank 7. The three tilting plates 13 on each side are distributed at equal vertical distances.

[0022] A first drive assembly 14 is fixedly installed on the bottom right side of the movable plate 11, extending to its top and fixedly connected to the outside of the rotating shaft 12. The first drive assembly 14 includes a drive motor 141. The drive motor 141 is a Y355 model. The output shaft of the drive motor 141 extends to the top of the movable plate 11 and is fixedly installed with a drive gear 142 located on the right side of the rotating shaft 12. A driven gear 143 with one end meshing with the drive gear 142 is fixedly installed on the outside of the rotating shaft 12.

[0023] A threaded rod 15 is movably installed on the left side of the right support plate 2, located below the movable plate 11 and extending to the left side of the left support plate 2. A second bearing is fixedly installed on the left side of the right support plate 2, located below the movable plate 11.

A driven bevel gear 193, with one end meshing with the drive bevel gear 192, is fixedly installed on the left side of the threaded rod 15.

[0025] In use, the Chinese herbal medicine slices to be dried are injected into the placement tank 7 through the through hole 4. Then, the cover 5 is closed, and the hot air fan 93 is started through the controller 10 to draw air from the drying tank 3 into the hot air fan 93 and heat the air. Finally, the hot air is sent into the drying tank 3, and the hot air enters the placement tank 7 through the air inlet 8 to heat and dry the Chinese herbal medicine slices. The evaporated water vapor enters the drying chamber 91 for dehumidification. The dehumidified air is then reintroduced into the drying tank 3 through the hot air fan 93 to dry the Chinese herbal medicine slices. At the same time, the drive motor 141 can be started to drive the drive gear 142 to rotate, which in turn drives the rotating shaft 12 and the tilting plate 13 to rotate through the driven gear 143, thereby turning the Chinese herbal medicine slices in the placement tank 7. Secondly, the drive bevel gear 192 can be driven to rotate through the servo motor 191. The driven bevel gear 193 drives the threaded rod 15 to rotate, and the threaded rod 15 rotates, causing the two sliders 17 to move relative to each other. This, in turn, drives the moving plate 11, the rotating shaft 12, and the flipping plate 13 to move upward as a whole via the connecting rod 18. Then, the servo motor 191 rotates in the opposite direction, thereby driving the threaded rod 15 to rotate in the opposite direction. At this time, the threaded rod 15 rotates, causing the two sliders 17 to move in opposite directions. This, in turn, drives the moving plate 11, the rotating shaft 12, and the flipping plate 13 to move downward as a whole via the connecting rod 18. Then, the servo motor 191 rotates in the forward direction again. This cycle repeats, causing the flipping plate 13 to move up and down. Thus, the flipping plate 13 moves up and down in coordination with the rotation, thereby expanding the flipping range and enabling the Chinese medicine slices in the container 7 to be fully flipped, so that the Chinese medicine slices can come into contact with the hot air, thereby ensuring that the Chinese medicine slices are heated evenly and are fully dried.

[0026] In summary, the low-temperature drying device for traditional Chinese medicine tablets rotates by starting the drive motor 141, which drives the drive gear 142 to rotate. This, in turn, drives the rotating shaft 12 and the tilting plate 13 to rotate via the driven gear 143, thus turning the traditional Chinese medicine tablets in the container 7. Simultaneously, the servo motor 191 can also rotate the drive bevel gear 192, which in turn drives the threaded rod 15 to rotate via the driven bevel gear 193. During rotation, the threaded rod 15 causes the two sliders 17 to move relative to each other, which in turn causes the moving plate 11, rotating shaft 12, and tilting plate 13 to move upwards via the connecting rod 18. Then, the servo motor 191 rotates in the opposite direction, causing the threaded rod 15 to rotate in the opposite direction. During this rotation, the threaded rod 15 causes the two sliders 17 to move in opposite directions, which in turn causes the moving plate 11 to move upwards via the connecting rod 18. 11. The rotating shaft 12 and the tilting plate 13 move downwards as a whole, and then the servo motor 191 rotates in the forward direction again. This cycle repeats, causing the tilting plate 13 to move up and down repeatedly. As the tilting plate 13 rotates, it moves up and down in coordination with the rotation to expand the tilting range, thereby enabling the Chinese medicine slices in the container 7 to be fully turned over, so that all the Chinese medicine slices can come into contact with the hot air. This ensures that the Chinese medicine slices are heated evenly, thus ensuring that the Chinese medicine slices are fully dried. Ultimately, this achieves the goal of good drying effect and solves the problem that existing low-temperature drying devices for Chinese medicine slices often dry large quantities of Chinese medicine slices by piling them up in the drying device. This causes the hot air to not reach the inside of the piled-up Chinese medicine slices, resulting in uneven heating and ineffective drying of the Chinese medicine slices.
