[0022] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0023] according to Figure 1-6 As shown, a capsule filling device for preparing capsule drugs includes a frame 1, on which a rotating seat 2 is provided. The rotating seat 2 is provided with several processing stations. The processing stations are provided with positioning components for positioning capsule support seats 3. The capsules are arranged in an orderly manner on the capsule support seats 3. A capsule filling mechanism is provided above one of the processing stations. The capsule filling mechanism includes several material bins 4. The material bins 4 are fixedly installed on a bracket 5. The inside of the material bins 4 is provided with guide rods 6. The bottom of the guide rods 6 is provided with an anti-clogging component. The anti-clogging component has a double cone structure.

[0024] In the above specific technical solution, by setting several processing stations on the rotating seat 2, the filling efficiency of the capsule can be effectively improved. A guide rod 6 is set inside the hopper 4, and an anti-blocking component is set at the bottom of the guide rod 6. The anti-blocking component has a double cone structure. With the anti-blocking component in the hopper 4, the powder agent at different positions in the hopper 4 falls at the same speed, and the powder agent flows as a whole. However, in the hopper 4 without the anti-blocking component, the powder agent surges towards the middle, indicating that the flow rate of the powder agent at different positions in the hopper 4 is different, which can easily cause bridging at the bottom of the hopper 4 and blockage at the bottom of the hopper 4. The tip of the double cone of the anti-blocking component effectively solves the problem of powder agent bridging and can prevent the hopper 4 from being blocked.

[0025] The anti-clogging material assembly includes a first cone 7 and a second cone 8. The taper of the first cone 7 is smaller than that of the second cone 8, while the taper of the second cone 8 is larger, which is beneficial for the powdered medicine to fall into the capsule.

[0026] The first cone 7 has several guide grooves 9 arranged along its circumference on its cone surface, which facilitates the powder medicine falling along the grooves.

[0027] The second cone 8 has a plurality of guide blades 10 arranged along its circumference on its cone surface, and the width of the guide blades 10 gradually decreases from top to bottom.

[0028] The tops of several guide rods 6 are connected to a drive motor 12 via a belt and pulley mechanism 11. The drive motor 12 is fixedly mounted on a bracket 5, and the bracket 5 is fixedly mounted on a frame 1.

[0029] In the above specific technical solution, the guide rod 6 is driven to rotate by the drive motor 12. During the rotation of the guide rod 6, the possibility of material blockage at the bottom of the hopper 4 can be further reduced. At the same time, the guide blade 10 is set to further guide the powder medicine, which is conducive to the powder medicine falling into the capsule. It is worth noting that the rotation speed of the guide rod 6 is low and will not affect the normal falling of the powder medicine.

[0030] A rotary motor 13 is installed on the frame 1. The rotary motor 13 is connected to the rotating shaft through the gear mechanism 14. The top of the rotating shaft is connected to the rotating seat 2. After the operator loads the capsules, the rotary motor 13 drives the rotating seat 2 to rotate and move to the bottom of the material hopper 4. Powder is filled into the capsules through the material hopper 4. After the powder is filled, the rotating seat 2 continues to rotate and rotates to the next station for further processing of the capsules. After processing, the rotating seat 2 rotates to the unloading station, where the operator unloads the capsules. By setting up multiple processing stations, the continuity of capsule filling is facilitated.

[0031] The positioning assembly includes a first guide rail 15 fixedly mounted on a rotating base 2. A movable plate 16 is slidably mounted on the first guide rail 15. The movable plate 16 is connected to a transverse lead screw 17 mounted on the rotating base 2 and connected to the output end of a drive motor 18. A second guide rail 19 is provided on the movable plate 16. The second guide rail 19 is perpendicular to the first guide rail 15 on a horizontal plane. A movable seat 20 is slidably mounted on the second guide rail 19. The movable seat 20 is connected to a longitudinal lead screw 21 mounted on the movable plate 16 and connected to a movable motor 22 fixedly mounted on the movable plate 16. L-shaped locking blocks 23 are provided at the four ends of the movable seat 20. The L-shaped locking blocks 23 engage with the bottom of the capsule support 3. The locking blocks facilitate the positioning of the capsule support. The positioning mechanism can drive the capsule support 3 to move horizontally, thereby achieving the filling of capsules neatly arranged on the capsule support 3.

[0032] The capsule support 3 is provided with handles 24 on both sides, which facilitates the replacement of new capsule support 3.

[0033] The bracket 5 is equipped with an electric telescopic rod 26 via a vertical plate 25. The output end of the electric telescopic rod 26 is connected to a baffle 27, which has a discharge hole corresponding to the bottom outlet of the hopper 4. When the central axis of the discharge hole coincides with the central axis of the bottom outlet of the hopper 4, the powdered medicine falls out. When the discharge hole and the bottom outlet of the hopper 4 are misaligned, the baffle 27 blocks the bottom outlet of the hopper 4. It is worth noting that the height of the baffle 27 is slightly higher than the height of the capsule on the capsule support 3, so it will not interfere with the rotating seat 2 when it rotates.

[0034] The above embodiments are merely exemplary embodiments of the present utility model and are not intended to limit the present utility model. The scope of protection of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present utility model.
