Technical Field
[0001] The utility model relates to the technical field of medicine packaging, in particular to a tablet quantitative device. Background Art
[0002] When the drugs are packaged after production, in order to fill a certain number of drugs in the packaging bottle, the drugs are often counted by a counter first, and most of the counting uses an induction probe. The number of drugs passing through the induction probe is finally obtained. In the process of specific application, it is found that during the movement of the drugs, some dust is easy to fall on them, and this dust will gradually accumulate on the induction probe, which will lead to a decrease in the sensitivity of the induction probe, and then the problem of inaccurate number counting will occur. Therefore, how to replace the probe counting with other operating methods to reduce the failure rate has become a technical problem that needs to be solved urgently. Utility Model Content

A weight scale is provided at the bottom of the accommodating cavity. When there are pills of sufficient weight in the accommodating cavity, the weight of the total pills can be known through the scale, and the number of pills in the accommodating cavity can be known through the weight of the total pills and the average weight of a single pill. Of course, in addition to this, the number of pills in the accommodating cavity can also be determined by the residence time of the accommodating cavity at the discharge pipe head and the time when a single pill falls into the accommodating cavity. A discharge port is provided at the outer end of the accommodating cavity, and end disks are installed at both ends of the rotating disk. The output shaft of the motor is connected to the end disk located on the inner side, and the discharge port is used for the discharge of pills.

[0022] A mounting boss 54 is mounted on the upper end of the vertical plate 1 , and a fixing pipe 53 is mounted on the outer end of the mounting boss 54 . The fixing pipe 53 is located above the baffle 41 .
[0023] A rotating disk 6 is rotatably provided inside the outer ring 30, and a plurality of accommodating cavities 60 are provided on the rotating disk 6. In the present embodiment, a weighing device is provided at the bottom of the accommodating cavity, and a concave structure portion is provided at the inner end of the accommodating cavity 60. Inclined surfaces are formed on both sides of the outer end of the concave structure portion, and the outer ends of the inclined surfaces extend inwardly. A discharge port 61 is provided at the outer end of the accommodating cavity 60, and end disks 62 are installed at both ends of the rotating disk 6. The output shaft of the motor 2 is connected to the end disk 62 located on the inner side.
[0024] The fixed tube 53 is sleeved with a movable tube 52, and the upper end of the movable tube 52 is formed with a conical shell 51, the upper end of the conical shell 51 is a large end, and the upper end of the conical shell 51 is provided with a placement tank 510, and the upper end of the placement tank 510 is provided with an upper ring 50, and a plurality of vertical rods 5 are provided on the upper ring 50, and the lower end of the vertical rod 5 is sleeved with a sleeve plate 10, and the sleeve plate 10 is installed on the upper end of the vertical plate 1, and the outer periphery of the placement tank 510 is installed with a down-extending plate 67, and the lower end of the down-extending plate 67 is rotatably provided with an action rod 66. A convex ring 63 is provided on the outer wall of the end plate 62 located on the outside, and a plurality of V-shaped grooves 64 are opened on the outer wall of the convex ring 63, and a circular arc groove 65 is provided between two adjacent V-shaped grooves 64, and the opening of the V-shaped groove 64 faces the center of the end plate 62, and the action rod 66 moves in the V-shaped groove 64 and the circular arc groove 65.
[0025] When operating this embodiment, the following steps are required:
[0026] The operator first fills a sufficient amount of processed pills into the placement tank 510.
[0027] Then start the motor 2, and the rotating disk 6 rotates under the drive of the motor 2. When the rotating disk 6 rotates, the discharge port 61 on one of the accommodating cavities 60 will be connected with the discharge pipe head 31, and the discharge port 61 of the other accommodating cavity 60 will be opposite to the rectangular tube 32.
[0028] Then, the baffle 41 is pulled by the cylinder 40 to be withdrawn from the discharge pipe head 31. Then, the pills in the placement tank 510 will enter the fixed pipe 53 and enter the accommodating chamber 60 one by one through the discharge pipe head 31. The weighing device arranged at the bottom of the accommodating chamber 60 will weigh the pills therein and calculate the number of pills.
