The peripheral array has a plurality of through slots for containing capsules. The bottom surface of the conveying core 323 is in contact with the baffle 324. The conveying core 323 can rotate freely. The conveying core 323 rotates to make the capsules in the main pipeline 31 fall into the through slots. The bottom of the through slots is blocked by the baffle 324, so that the capsules can be filled into the through slots. Since the volume of the through slots is limited, the capsules entering the through slots are quantitative. When the conveying core 323 rotates, when the through slots containing the capsules rotate to the opening position of the baffle 324, the capsules are automatically discharged from the through slots.

[0033] A cover plate 321 is provided above the conveying core 323, and the cover plate 321 is fixedly installed on the main pipeline 31. An opening is provided on the cover plate 321, and the cover plate 321 connects the main pipeline 31 with the conveying core 323 through the opening.

The movable plug 344 is fan-shaped, and its radius is equal to the inner diameter of the dispensing sleeve 342. The movable plug can rotate freely in the dispensing sleeve 342 The second motor 343 is fixedly installed on one end of the dispensing sleeve 342 away from the bracket 341, and the output end of the second motor 343 is connected to the movable plug 344. The second motor 343 provides power for the rotation of the movable plug 344. There are no less than two dispensing pipes 345 connected to the dispensing sleeve 342, and the dispensing pipes 345 are communicated with the inner cavity of the dispensing sleeve 342. During the rotation of the movable plug 344, different dispensing pipes 345 can be blocked respectively, thereby realizing the function of discharging materials from different dispensing pipes 345.

[0035] Combination Figure 2 As shown, the containing box 2 includes a box body 22, and the box body 22 is fixedly mounted on the bottom plate 1 through a support rod 21.

After the capsule is added to the box body 22, the feeding plate 23 is pressed by the gravity of the capsule, and then the first spring 24 is compressed. As the capsule is discharged from the discharge port, the total weight of the capsule in the box body 22 is reduced. When the total weight of the capsule is reduced, the first spring 24 releases its elastic potential energy, so that the capsule can remain submerged in the discharge port 25.

[0036] Example 2

[0037] Combination Figure 1 , Fig. 9 As shown, it also includes a barrel 4 for quantitative delivery of capsules, the barrel 4 includes a supporting structure 41 installed on the base plate 1, a cylinder 42 and a conveying structure 43 that can slide on the supporting structure 41 to remove the cylinder 42 are installed on the supporting structure 41, the cylinder 42 is located below the distribution tube 345, and the number of the cylinder 42 is the same as the number of the distribution tube 345.

[0038] Combination Fig.10As shown, the bearing structure 41 includes a bearing frame 411, and the bearing frame 411 is installed on the bottom plate 1 through a support leg 418. An L-groove 412 for installing the cylinder 42 is provided on the bearing frame 411. One end of the L-groove 412 is used to install the cylinder 42, and the other end of the L-groove 412 is used to take out the cylinder 42.

The second spring 415 is exerted with pressure due to the weight of the capsule. At this time, the placement block 413 drives the guide rod 414 to move downward. When the guide rod 414 moves to the point where the sensor contacts the U-shaped frame 416, the required weight is reached. At this time, the cylinder 42 is at the junction of the two ends of the L-groove 412, so that the cylinder can slide out from the other end of the L-groove 412. The sensor will drive the second motor 343 to rotate through the external control module, so that the capsule is discharged from the other distribution pipe 345, thereby realizing the function of the other cylinder 42 to contain, and then realizing the function of quantitative filling.

When the telescopic plate 432 moves to a position beyond the cylinder 42, the spring releases its elastic potential energy and the telescopic plate 432 extends from the conveying plate 431. When the conveying plate moves in the opposite direction, the telescopic plate 432 contacts the side wall of the cylinder 42 and pushes the cylinder 42 out. To prevent the cylinder 42 from being tilted during movement due to the force of the telescopic plate 432, a limiting plate 433 is fixedly installed at one end of the conveying plate 431 away from the telescopic plate 432. The distance between the limiting plate 433 and the telescopic plate 432 is not less than the diameter of the cylinder 42. The limiting plate 433 supports the cylinder 42 to prevent the cylinder 42 from being tilted during movement due to the force of the telescopic plate 432.
