DETAILED DESCRIPTION OF THE EMBODIMENTS

(6) Referring to FIGS. 1 to 4, a measuring device of Chinese medicine granules in accordance with the present disclosure includes a dispensing tray 1, a fixed discharging cover 2, and a discharging driving cover 3 mounted coaxially. The dispensing tray 1 and the discharging driving cover 3 are sleeved on an inner side and an outer side of the fixed discharging cover 2, respectively. The dispensing tray 1 and the discharging driving cover 3 are fixedly connected and capable of rotating about a central axis. The dispensing tray 1, the fixed discharging cover 2, and the discharging driving cover are provided with the same quantity of storage holes 11, measuring holes 21, and discharging holes 31, respectively. The storage holes 11 and the discharging holes 31 have larger sizes than those of the measuring holes 21. When the discharging driving cover 3 is rotated, the storage holes 11 can be in communication with the measuring holes 21, or the measuring holes 21 can be in communication with the discharging holes 31.

(7) The dispensing tray 1 is further provided with a discharging anti-blocking structure 4. The discharging anti-blocking structure 4 includes a bottom case 41, a briquetting holder 42, an anti-blocking briquette 43, a spring 44, and a cover 45 matched with the bottom case. The bottom case 41 is fixed on the dispensing tray 1 and offsets from the storage hole 11, that is, the bottom case 41 does not block the storage hole 11. The bottom case 41 is provided with dispensing holes 46 therein, which are positioned directly above the discharging holes 31. Each of the dispensing holes 46 is provided with one anti-blocking briquette 43 therein.

(8) The briquetting holder 42 is disposed in the bottom case and fixedly connected to the anti-blocking briquette 43. The spring 44 is sleeved on a center of the briquetting holder 42 and a free end of the spring 44 is in contact with the cover 45. An edge of a bottom surface of the anti-blocking briquette 43 is provided with a round chamfer. Under the action of the spring 44, the bottom surface of the anti-blocking briquette 43 may be in contact with an inner bottom surface of the fixed discharging cover 2 through the dispensing hole. During a rotation of the discharging driving cover 3, the round chamfer of the anti-blocking briquette 43 may slide into and out of the measuring hole 21.

(9) In addition, the measuring device of Chinese medicine granules in accordance with the present disclosure further includes a tag holder 5. The tag holder 5 is composed by a hollow frame 51 and a top cover 52 matched with the frame. The frame 51 is fixed onto the cover 45 of the discharging anti-blocking structure. By providing the tag holder 5, a radio frequency identification (RFID) can be placed in the hollow frame 51 for identification and verification by the discharging device.

(10) In addition, there are six storage holes 11, six measuring holes 21, six discharging holes 31, and six dispensing holes 46.

(11) The bottom case 41 has a shape of “*” and is integrally formed with the dispensing tray. Six storage cavities 47 are formed between an outer side of the bottom case 41 having the shape of “*” and the dispensing tray. Each of the storage cavities 47 is provided with one storage hole 11 on a bottom surface thereof.

(12) In addition, the briquetting holder 42 and the anti-blocking briquette 43 are integrally formed.

(13) In the present embodiment, the aforementioned fixed discharging cover 2 is further provided with a mounting through hole 22 at a center of a bottom surface thereof. The aforementioned measuring holes 21 are uniformly arranged along an outer side of an edge of the mounting through hole 22. A bottom surface of the aforementioned discharging driving cover 3 is provided with a circular flange 32 adapted to a size of the mounting through hole 22. The circular flange 32 is provided with a polygonal latching groove 33 and a mounting post 34 disposed on the center of the bottom surface of the discharging driving cover 3. A bottom surface of the dispensing tray 1 is provided with a polygonal latching flange 13 matching with the polygonal latching groove 33. When mounting the dispensing tray 1, the polygonal latching flange 13 of the dispensing tray 1 is engaged with the polygonal latching groove 33, and the dispensing tray 1 is fixed to the mounting post 34 by a screw passing through the cover 45 and the dispensing tray 1.

(14) In addition, the inner bottom surface of the fixed discharging cover 2 is provided with a first annular guiding groove 23, and an inner bottom surface of the discharging driving cover 3 is provided with a second annular guiding groove 35. The fixed discharging cover 2 is provided with a first annular latching flange 24 on an outer bottom surface thereof. The first annular latching flange 24 can be latched in the second annular guiding groove 35. A lower surface of the dispensing tray 1 is provided with a second latching flange 14 latched in the first annular guiding groove 23. The aforementioned storage holes 11 are disposed in an area of the second annular latching flange 14 of the dispensing tray 1, the measuring holes 21 are disposed in the first annular guiding groove 23, and the discharging holes 31 are disposed in the second annular guiding groove 35. By providing the first annular guiding groove 23 and the second annular guiding groove 35, the movement trajectory of the medicine granules may be restricted in the annular guiding grooves, thereby preventing the external dispersion to hinder the rotation.

(15) In addition, the aforementioned fixed discharging cover 2 is provided with a mounting thread 25 on an inner side wall thereof and is provided with a positioning anti-rotation lug 26 and anti-slip ribs 27 on an outer side wall thereof. The anti-slip ribs 27 are uniformly distributed on the outer side wall. The aforementioned discharging driving cover 3 is provided with rotating limiting ribs 36 on an outer side wall thereof.

(16) When the measuring device of Chinese medicine granules in accordance with the present disclosure is used, the fixed discharging cover 2 is threadedly connected to a discharging port of a discharging vessel. After turning over the measuring device, the positioning anti-rotation lug 26 on the fixed discharging cover 2 is tightly latched and fixed to the station of a peripheral leakage device, and the rotating limiting rib 36 is inserted into a latching groove of a rotary driving component of the peripheral leakage device, and driven to rotate by a servo motor. When the storage holes 11 are in communication with the measuring holes 21, the medicine granules in the discharging vessel fall into the measuring holes 21. When the measuring device is further rotated, when the measuring holes 21 are aligned and in communication with the discharging holes 31, the round chamfer of the anti-blocking briquette 43 slides into the measuring holes 21 and collides with the Chinese medicine granules in the measuring holes, causing the Chinese medicine granules to move downwards and fall down through the discharging holes 31. The rotation and the discharging are repeated until the discharging amount is fulfilled. The servo motor stops rotating.

(17) Since the measuring holes 21 are disposed on the fixed discharging cover 2 located in the middle layer, this portion is stay still during operation. The relative movement between the dispensing tray and the discharging driving cover which are fixedly connected and rotated about the central axis ensures the smoothness of the rotation and makes the measurement of the Chinese medicine granules more accurate.

(18) The above description is only used for illustrating the technical solutions of the present disclosure, and is not intended to limit the protection scope of the present disclosure. Simple modification or equivalent replacement can be made by those skilled in the art to the technical solutions of the present disclosure, without departing from the essence and the scope of the technical solutions of the present disclosure.
