[0003] The process of capsule production is roughly as follows: delivering capsule shells, sorting capsules, separating capsules, filling, rejecting waste, locking capsules, and discharging capsules; the capsule separation principle of the current capsule machine can refer to a capsule separation mechanism for a capsule filling machine provided by a Chinese invention patent (CN202310588823.X), which includes a base and a rotating seat, the base is provided with a suction cup base, the rotating seat is provided with a capsule shell upper seat and a capsule shell lower seat, and the capsule shell upper seat and the capsule shell lower seat are both provided with capsule shell openings, the suction cup base is provided with a plurality of vacuum suction columns, and the number of vacuum suction columns is the same as the capsule shell opening, and the inner wall of the capsule shell opening of the capsule shell lower seat of the vacuum suction column is interference fit. By setting up the vacuum suction column, the capsule shell opening is completely adsorbed to prevent vacuum leakage, and achieve a better capsule separation effect. And by adding structures such as suction channels and diaphragms, the vacuum suction column can produce a greater adsorption force on the lower capsule skin, thereby further enhancing the capsule separation effect, ensuring that the merged and relatively compact capsule skin can also be split. By installing a capsule-splitting cutter on the device, the upper and lower capsule skins that are not well divided are separated.

[0021] It should be noted that the directional and positional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "top", "bottom", "side", etc., are only references to the directions or positions in the attached drawings.

[0022] Embodiment 1

[0023] As Figure 1 shown, the capsule machine developed by the applicant includes a capsule machine frame, a blanking mechanism, and a filling mechanism. The blanking mechanism includes a conical hopper, a stirring paddle disposed in the conical hopper, and a blanking assembly. A blanking channel and a discharge port are extended and provided below the conical hopper. The blanking assembly includes a feeding screw extending from the conical hopper into the blanking channel. The feeding screw rotates coaxially with the stirring paddle, and a valve is provided at one end of the feeding screw away from the conical hopper.

[0024] The filling mechanism includes a metering disc assembly 208, a swinging knife 209, and a central rotating disc 211. As Figures 1-4 shown, the central rotating disc 211 is circumferentially provided with a capsule splitting device of the capsule machine including a splitting die 210. The splitting die 210 includes an upper glue die 310 and a lower glue die 311. The splitting device further includes a capsule sucking device cooperating with the splitting die 210. The capsule sucking device includes a capsule sucking disc 101 and a vacuum capsule sucking seat 102. The upper glue die 310 and the lower glue die 311 are respectively coaxially provided with an upper die hole and a lower die hole to accommodate a capsule cap and a capsule lower shell, and the diameter of the lower die hole of the lower glue die 31 is smaller than the diameter of the upper die hole of the upper glue die 310, so that a limiting step is formed between the upper die hole and the lower die hole. The capsule sucking disc 101 includes a suction hole connected to a vacuum pipeline and a disc-shaped structure extending outside the suction hole. The capsule sucking disc 101 is hermetically fitted with the lower die hole of the lower glue die 31 and evacuated, so that the capsule cap and the capsule lower shell are separated (since there is a limiting step between the upper die hole and the lower die hole, the capsule cap is limited, while the capsule lower shell is sucked and dropped. It can be understood that although the through hole at the bottom of the lower glue die 31 communicates with the suction hole, there must be a limiting structure at the bottom of the through hole of the lower glue die 31 to prevent the capsule lower shell from escaping from the lower die hole of the lower glue die 31).

[0025] The die driving device includes an upper glue die driving rod 3101 connected to the upper glue die 310 and a lower glue die driving rod 3111 connected to the lower glue die 311. The upper glue die driving rod 3101 drives the upper glue die 310 to move upward, and the lower glue die driving rod 3111 drives the lower glue die 311 to move away from the central rotating disc 211 to expose the capsule lower shell in the lower glue die 31 for filling.

[0026] Further, a central rotating disk 211 is circumferentially provided with a number of sub-capsule molds 210, and a number of corresponding upper die holes and lower die holes are provided on each sub-capsule mold 210; a capsule sucking device is matched with a plurality of sub-capsule molds 210.

[0027] The capsule sucking device further includes a guide seat 105 and a guide rod 104 arranged on the guide seat 105. The guide seat 105 drives the vacuum capsule sucking seat 102 to lift through the guide rod 104 to control the cooperation between the capsule sucking disk 101 and the lower rubber mold 31.

[0028] A flexible buffer column 1011 (hollow and communicated with the vacuum suction pipe) is arranged between the capsule sucking disk 101 and the vacuum capsule sucking seat 102. When the guide rod 104 drives the capsule sucking disk 101 to fit against the bottom of the lower rubber mold 31, it is pushed until the flexible buffer column 1011 is compressed, so that the bottom of the vacuum capsule sucking seat 102 and the lower rubber mold 31 fit more closely. The buffer column and the capsule sucking disk are integrally formed (the material is silicone rubber) and are connected to the vacuum capsule sucking seat by bolts, so that the noise is small, the service life of the capsule sucking disk is long, and it is convenient for replacement and maintenance.

[0029] The capsule sucking device is connected to a vacuum suction pipe 106, and the vacuum suction pipe 106 is connected to a three-way pipe 107 and a vacuum pump; the vacuum suction pipe 106 passes through the capsule seat fixing plate and communicates with the vacuum capsule sucking seat 102, and the bottom is connected to the three-way pipe 107 and is connected to the vacuum pump through the three-way pipe 107. A vacuum pressure regulating function is also designed. The three-way pipe 107 is connected to a regulating valve 108 to regulate the suction force of the capsule sucking disk 101 on the capsule; a connecting block 1100 connects the vacuum suction pipe 106 and the guide rod 104, and the connecting block 1100 cooperates with the cam to realize reciprocating up and down movement, so that when the capsule sucking disk 101 moves upward, it closely adheres to the lower surface of the lower rubber mold, the empty capsule falls, the capsule cap is left on the upper rubber mold by the step stop column of the upper rubber mold 310, and the capsule body is separated from the capsule cap under the action of the vacuum suction force and falls into the lower capsule mold.

[0030] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
