[0040] Example 3

[0041] Based on Example 1, see Figure 1 and Figure 5 shown

[0042] The sealing mechanism 506 includes a top plate 5061, which is placed on the first hopper 501 and the second hopper 502. A connecting plate 5062 is integrally formed on the top plate 5061, and a convex plate 5063 is fixedly connected to the top plate 5061. By using the top plate 5061, the connecting plate 5062 and the convex plate 5063 in coordination, the discharge plate 2 can be shielded to achieve a dust-proof effect, prevent dust from adhering to the discharge plate 2, and avoid contamination of the tablets.

The first support plate 7 and the second support plate 8 are in contact with the movable plate 503. By setting the first support plate 7 and the second support plate 8, when the movable plate 503 moves, the first support plate 7, the second support plate 8 and the first hopper 501 clamp the movable plate 503, which can prevent the movable plate 503 from deflecting during movement, thereby limiting the movable plate 503.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] The working principle of the present invention is as follows: the first hopper 501 and the second hopper 502 are both placed in the discharge plate 2, and then the first hopper 501 and the second hopper 502 are fixed to the fixed plate 5041 by using bolts 5042, and the bottle body is placed below the discharge port of the second hopper 502, and then the top plate 5061 is placed on the fixed plate 5041, and the convex plate 5063 is used to clamp the first hopper 501, so as to prevent the top plate 5061 from sliding off the fixed plate 5041. By using the top plate 5061, the connecting plate 5062 and the convex plate 5063 in conjunction with each other, the discharge plate 2 can be shielded to achieve a dustproof effect, thereby preventing dust from adhering to the discharge plate 2 and avoiding contamination of the tablets. After the medicine tableting process, the tablet pushing device provided on the tablet press body 1 is used to transport and take out the compacted tablets. Thereafter, the compacted tablets fall into the first hopper 501, and the first hopper 501 is used to collect the compacted tablets. Thereafter, by pressing one end of the pressing rod 5101, the pressing rod 5101 rotates around the support shaft 5102, and the pressing rod 5101 drives the connecting rod 508 to move, and the connecting rod 508 drives the movable plate 503 to move, and the spring 5091 is in a compressed state under the action of the first support plate 7 and the second support plate 8. When the movable plate 503 moves, the first support plate 7, the second support plate 8 and the first hopper 501 clamp the movable plate 503. It can prevent the movable plate 503 from deflecting during movement, and play the role of limiting the movable plate 503. Afterwards, the first through slot 507 is aligned with the discharge outlet of the first hopper 501, and the compacted tablets collected in the first hopper 501 will be discharged through the first through slot 507. Afterwards, the compacted tablets fall into the second hopper 502, and then fall into the bottle body through the discharge outlet of the second hopper 502 for collection. When the bottle body needs to be replaced, at this time, the pressing rod 5101 is released, and then under the action of the spring 5091, the spring 5091 changes from a compressed state to its original state, thereby applying force to the movable plate 503, and then the first through slot 507 and the discharge outlet of the first hopper 501 are in a misaligned state. , so that the compacted tablets in the first hopper 501 are no longer discharged. At this time, the bottle body can be replaced. After replacing the bottle body, the above steps can be repeated to continue bottling the compacted tablets. At the same time, when it is necessary to continuously discharge the compacted tablets, the rotating block 63 can be rotated, thereby driving the screw rod 61 to rotate, and then the second through hole 4 and the third through hole 505 have a limiting effect on the positioning card 62, and then the positioning card 62 will move, and then the second through groove 64 can be used to drive the pressing rod 5101 to move, and the positioning card 62 is used to position the pressing rod 5101, so that the first through groove 507 and the discharge port of the first hopper 501 are always in an aligned state, which is convenient for the continuous discharge of tablets for collection and easy use.
