[0024] In this embodiment, an empty capsule is put into the funnel at the top of the fixed tube 141. When the capsule shell enters the fixed tube 141, the outer shell end of the capsule is always oriented when the capsule enters the adjusting frame 146 by rotating the frame 142 and adjusting the dial 143, so that the capsule can be inserted into the upper die groove 93, and the capsule outer frame is located in the upper die seat 91, and the capsule inner shell is located in the lower die seat 92, and the Chinese medicine powder is put into the powder tank 16; The rotating disc 3 is driven to rotate to the bottom end of the feeding structure 18 by the rotating structure 4, and the material is injected into the inner shell of the capsule by the feeding structure 18. The flexible screw rod 182 is driven to rotate by the medicine feeding motor 183, so that the material in the medicine powder tank 16 is pushed into the inside of the discharge pipe 181, and the material is discharged through the discharge pipe 181. Since the discharge pipe 181 is inserted into the inside of the positioning pipe 185 and the discharge pipe is bent and extended downward, the bent part of the discharge pipe 181 is coaxially arranged with the positioning pipe 185, so that the medicine powder can be effectively transferred to the inside of the capsule inner shell, so as to achieve the purpose of filling the medicine. After the injection is completed, the rotating disk 3 continues to rotate, and when the lower mold base 92 rotates to the bottom side of the positioning plate 6, and the upper mold base 91 rotating plate 5 and the driving structure 7 rotate to the positioning plate 6, the electric telescopic rod 113 pushes the sliding plate 111 to move upward, so that the lower mold base 92 pushes the capsule inner shell to move upward, so that the capsule inner shell is inserted into the inside of the capsule outer shell. Figure 7 As shown, the interior of the positioning plate 6 is arc-shaped, which can not only form a supporting force for the capsule shell to facilitate the closing of the capsule shell and the capsule inner shell, but also form a guide through the arc-shaped part so that the capsule can be discharged through the arc-shaped part after closing.

[0025] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the rotating structure 4 includes a connecting tube 41, which is fixedly installed on the top of the base plate and sleeved on the outer peripheral wall of the connecting shaft 2. The interior of the connecting tube 41 is rotatably connected with a driving gear ring 42, which is fixedly connected to the bottom end of the rotating disk 3 and coaxially arranged with the rotating disk 3. A turntable motor 43 is arranged inside the connecting tube 41, and a turntable gear 44 meshing with the driving gear ring 42 is arranged on the motor shaft of the turntable motor 43.

[0026] In this embodiment, the turntable motor 43 drives the driving gear ring 42 and the rotating disk 3 to rotate through the turntable gear 44, which is used to adjust the position of the lower mold base 92 and transmit the lower mold base 92 to the bottom end of different mechanisms to complete the steps of opening the capsule, filling the powder and closing the capsule. The turntable motor 43 is a servo motor to facilitate controlling the rotation angle of the rotating disk 3.

[0027] In a further preferred embodiment of the present invention, Figure 1-7As shown, the driving structure 7 includes a mounting plate 71, which is fixedly arranged on the side wall of the positioning plate 6, a driving motor 72 is arranged inside the mounting plate 71, a driving gear 73 is arranged at the bottom end of the driving motor 72, and an outer ring gear 74 is arranged coaxially with the connecting shaft 2 on the outer side wall of the rotating plate 5, and the outer ring gear 74 is meshed with the driving gear 73.

[0028] In this embodiment, the driving motor 72 controls the driving gear 73 to rotate, and then the driving gear 73 and the outer gear ring 74 cooperate to drive the rotating plate 5 to rotate. The turntable motor 43 is a servo motor, so as to control the rotation angle of the rotating plate 5, so that the rotating plate 5 drives the upper mold base 91 to move to the position of the positioning plate 6, corresponding to the lower mold base 92 after filling with medicine powder, so as to close the capsule through the air pressure regulating device 11.

[0029] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the capsule opening module 9 includes an upper mold base 91 and a lower mold base 92. The upper mold base 91 is provided with a plurality of evenly distributed upper mold grooves 93. An annular retaining ring 94 is provided at the inner bottom end of the upper mold groove 93. The diameter of the upper mold groove 93 is equal to the outer shell diameter of the capsule.

[0030] The lower die seat 92 is provided with a plurality of evenly distributed lower die grooves 95 . The bottom of the lower die groove 95 is arranged in the same arc shape as the capsule inner shell. The bottom groove wall of the lower die groove 95 is provided with air suction holes 96 .

[0031] In this embodiment, by setting the upper die groove, when the capsule falls into the interior of the upper die groove 93, the capsule outer shell is stuck, and the capsule inner shell slides into the interior of the lower die groove 95, as shown in FIG. Figure 3 As shown, when negative pressure is formed by the air pressure regulating device 11, the capsule inner shell is sucked through the suction hole 96, and the lower mold base 92 is stretched downward to pull the capsule inner shell out of the capsule outer shell, thereby achieving the purpose of separating the capsule, and the lower mold base 92 moves downward, and the part of the capsule inner shell that is longer than the capsule outer shell will slide into the interior of the mounting groove 8, which can effectively avoid the capsule inner shell from colliding and causing deformation.

[0032] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the air pressure regulating device 11 includes a sliding plate 111, which is slidably installed inside the guide outer frame 10 and is slidably connected to the guide outer frame 10. An extension frame 112 is provided at the bottom end of the guide outer frame 10, and an electric telescopic rod 113 is provided inside the extension outer frame 112, and the electric telescopic rod 113 is fixedly connected to the bottom end of the sliding plate 111.

[0033] In this embodiment, the position of the sliding plate 111 inside the guide outer frame 10 and the extension outer frame 112 is controlled by setting the electric telescopic rod 113 to adjust the gap between the sliding plate 111 and the lower mold base 92, so as to generate negative pressure to attract the lower mold base 92 downward. Since the bottom end of the lower mold groove 95 is arranged in the same arc shape as the capsule inner shell, when the capsule is inserted into the lower mold groove 95, the suction hole 96 can be closed, and the capsule shell can be effectively adsorbed by the negative pressure, so that the capsule can be effectively separated during the downward movement of the lower mold base 92. On the other hand, when the lower die base 92 rotates to the bottom side of the positioning plate 6 and the upper die base 91 rotates to the positioning plate 6 under the influence of the rotating plate 5 and the driving structure 7, the electric telescopic rod 113 pushes the sliding plate 111 to move upward, so that the lower die base 92 pushes the capsule inner shell to move upward, so that the capsule inner shell is inserted into the inside of the capsule outer shell, as shown in FIG. Figure 7 As shown, the interior of the positioning plate 6 is arc-shaped, which can not only form a supporting force for the capsule shell to facilitate the closing of the capsule shell and the capsule inner shell, but also form a guide through the arc-shaped part so that the capsule can be discharged through the arc-shaped part after closing.

[0034] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the capsule transmission device 14 includes a fixed tube 141, a rotating frame 142 is provided at the bottom end of the fixed tube 141, an adjusting dial 143 is provided inside the rotating frame 142, a shunt tube 144 is provided inside the adjusting dial 143 and is coaxial with the fixed tube 141, a pop-up retaining spring 145 is provided inside the shunt tube 144, an adjusting frame 146 is provided at the bottom end of the rotating frame 142, the width of the adjusting frame 146 is equal to the diameter of the capsule outer frame, a discharge hole 147 corresponding to the upper mold groove 93 is provided at the bottom end of the adjusting frame 146, an air guide hole 148 is provided on the back side of the adjusting frame 146, and an arc guide plate 149 is provided inside the adjusting frame 146.

[0035] In this embodiment, the capsule shell is dropped into the interior of the fixed tube 141 through the funnel at the top of the fixed tube 141. When the shell end of the capsule enters the interior of the fixed tube 141, the arc of the shell end of the capsule pushes the pop-up retaining spring 145, so that the pop-up retaining spring 145 is close to the tube wall of the shunt tube 144, so that the capsule can slide downward smoothly until it enters the interior of the adjustment frame 146. Since the internal width diameter of the adjustment frame 146 is equal to the diameter of the capsule shell, the interior of the adjustment frame 146 will form a large friction force on the capsule shell. At this time, the two air guide holes 148 take in air at the same time. It can effectively push the capsule to deflect. Since the capsule shell is located at the bottom side and the friction force is large, the inner shell of the capsule will tilt toward the discharge hole 147. At this time, the capsule forms a tilted shape. Therefore, only the outer shell of the capsule is affected by the wind force of the air guide hole 148, which can effectively push the capsule to slide and enter the discharge hole 147 through the guidance of the arc-shaped guide plate 149, and fall into the interior of the upper mold groove 93. At this time, the inner shell of the capsule corresponds to the lower mold seat 92, and the outer shell of the capsule corresponds to the upper mold seat 91, so that the capsule can be separated by the air pressure regulating device 11; On the other hand, if the inner shell end of the capsule enters the interior of the shunt tube 144, the inner shell end of the capsule pushes the pop-up retaining spring 145 to move, so that the pop-up retaining spring 145 abuts against the edge of the capsule outer shell. Figure 4 As shown, the capsule cannot move downward. At this time, the sensor at the top of the pop-up retaining spring 145 contacts the capsule shell and controls the motor inside the rotating frame 142 to rotate the adjusting dial 143 180 degrees. At this time, the capsule shell rotates to the bottom and slides into the inside of the adjusting frame 146. Similarly, the capsule is pushed into the inside of the discharge hole 147 through the air guide hole 148.

[0036] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the feeding structure 18 includes a discharge pipe 181, which is connected to the powder tank 16, and the number of the discharge pipes 181 is equal to the number of the upper mold grooves 93. A flexible spiral rod 182 is arranged inside the discharge pipe 181, and a medicine feeding motor 183 connected to the flexible spiral rod 182 is arranged inside the powder tank 16. A medicine discharge plate 184 is arranged on the outer peripheral wall of the discharge pipe 181, and a positioning tube 185 corresponding to the upper mold groove 93 is arranged inside the medicine discharge plate 184. The discharge pipe 181 is inserted into the positioning tube 185 and bends downward to extend. The bent part of the discharge pipe 181 is coaxially arranged with the positioning tube 185.

[0037] In this embodiment, the flexible spiral rod 182 is driven to rotate by the medicine delivery motor 183, so that the material inside the medicine powder tank 16 is pushed into the inside of the discharge pipe 181, and the material is discharged through the discharge pipe 181. Since the discharge pipe 181 is inserted into the inside of the positioning tube 185 and the discharge pipe is bent and extended downward, the bent part of the discharge pipe 181 is coaxially arranged with the positioning tube 185, so that the medicine powder can be effectively transferred to the inside of the capsule inner shell, thereby achieving the purpose of filling the medicine.

[0038] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the stirring structure 17 includes a stirring motor 171 located at the bottom end of the medicine powder tank 16 , and a stirring shaft 172 penetrating the medicine powder tank 16 is disposed at the top end of the stirring motor 171 .

[0039] In this embodiment, the interior of the powder tank 16 is stirred by the setting of the stirring motor 171 and the stirring shaft 172, so that the Chinese medicine powder inside is more uniform, thereby achieving the purpose of improving the uniformity of filling. The outer wall of the stirring shaft 172 is provided with a stirring structure, but since the stirring structure is relatively common, it is not described in detail. Embodiment 2:

Since the discharge pipe 181 is inserted into the inside of the positioning pipe 185 and the discharge pipe is bent and extended downward, the bent part of the discharge pipe 181 is coaxially arranged with the positioning pipe 185, so that the medicine powder can be effectively transferred to the inside of the capsule inner shell, so as to achieve the purpose of filling medicine; S104, closing the capsule: after the injection is completed, the rotating disk 3 continues to rotate, and when the lower mold base 92 rotates to the bottom side of the positioning plate 6, and the upper mold base 91 rotating plate 5 and the driving structure 7 rotate to the positioning plate 6, the electric telescopic rod 113 pushes the sliding plate 111 to move upward, so that the lower mold base 92 pushes the capsule inner shell to move upward, so that the capsule inner shell is inserted into the inside of the capsule outer shell, as shown in FIG.
