Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1:

[0034] See also Figure 1 - Figure 4 As shown, a medicine batch packaging device includes a medicine packaging machine frame 1, a feed port 2, a distribution bin 3, a packaging bin 4 and a sealer 5. The feed port 2 is arranged at the top of the medicine packaging machine frame 1, the distribution bin 3 and the packaging bin 4 are arranged in the middle of the medicine packaging machine frame 1, the packaging bin 4 is located below the two distribution bins 3, and the sealer 5 is installed at the bottom of the packaging bin 4. Some medicines need to be added with a certain proportion of special medicines separately, or some medicines need to be prepared according to different proportions. The medicines are placed inside the two feed ports 2, and the feed ports 2 fall into the inside of the two distribution bins 3, so that the distribution bins 3 are filled with the required reagents. A cylinder 10 is provided in the middle of the medicine packaging machine frame 1 and on the back side of the distribution bin 3, and a closing plate 7 is fixedly installed on the end of the cylinder 10, and the closing plate 7 is slidably connected to the bottom end of the distribution bin 3. When the medicine needs to be put into the package, the cylinder 10 can be retracted to move the closing plate 7 at the bottom end of the distribution bin 3, so that the reagent in the distribution bin 3 is added to the inside of the packaging bin 4 for packaging, and the packaging bag is packaged by the packager 5; the inside of the two distribution bins 3 is provided with a quantity adjustment structure 6, and the quantity adjustment structure 6 includes a stepping motor 61, which is arranged on one side wall of the distribution bin 3, and the stepping motor 61 is installed It is installed on one side of the material distribution bin 3, and a threaded rod 62 is installed at the end of the stepper motor 61. The threaded rod 62 is horizontally mounted inside the material distribution bin 3, and a partition plate 63 is arranged in the middle of the threaded rod 62 and located inside the material distribution bin 3. A threaded sleeve 64 is welded in the middle of the partition plate 63, and the threaded sleeve 64 of the partition plate 63 is threadedly connected with the threaded rod 62. Starting the stepper motor 61 makes the stepper motor 61 drive the threaded rod 62 to rotate, and the threaded rod 62 and the threaded sleeve 64 of the partition plate 63 are transmitted, so that the partition plate 63 moves along the inside of the material distribution bin 3, and can be adjusted to enter the inside of the packaging bin 4 as needed. The medicines will fall into the packaging bag in a certain proportion after the partition plate 63 inside the two distribution bins 3 moves and the two closing plates 7 are opened and closed at the same time when the two distribution bins 3 are filled with medicines. A fixing plate 66 is welded to the top of the partition plate 63, and a reserved groove 65 is provided on the side wall of the distribution bin 3 near the stepping motor 61. The fixing plate 66 is slidably connected to the inside of the reserved groove 65. The partition plate 63 is used to separate the internal bottom space of the distribution bin 3, and the space for falling materials in the middle part of the distribution bin 3 is blocked by the fixing plate 66, so that the partition plate 63 will not affect the proportion of medicines when it is inside the distribution bin 3.

[0035] See also Figure 3 and Figure 4As shown, the length of the fixed plate 66 is matched with the length of the distribution bin 3, the cross-sectional shape of the partition plate 63 is matched with the cross-sectional shape of the distribution bin 3, the edge of the partition plate 63 is slidably connected with the inner wall of the distribution bin 3, and the shape of the partition plate 63 and the inner wall of the distribution bin 3 prevents the medicine from leaking out from the gap therebetween, ensuring that the medicine enters the interior of the packaging bin 4 in a specific proportion, and the partition plates 63 inside the two distribution bins 3 adjust their positions in a certain proportion, and the stepper motor 61 rotates to drive the threaded rod 62 to rotate, and the partition plate 63 will move along the threaded rod 62, at this time, the interior of the distribution bin 3 can be divided into two spaces, so that the ratio of the reagents in the two spaces inside the distribution bins 3 is adjusted.

[0036] It should be noted that different medicines are introduced into the distribution bin 3 from different feed ports 2, and after the two distribution bins 3 are filled, the closing plate 7 can be opened and closed by simultaneously extending and retracting the two cylinders 10, so that the medicines can be simultaneously sent to the packaging bin 4 for packaging, and sealed and packaged by the encapsulator 5. When the proportion of the medicines needs to be changed for packaging, the proportion of the medicines in the two distribution bins 3 can be adjusted by the quantity adjustment structure 6. Specifically, the stepper motor 61 of the two distribution bins 3 is started, and the stepper motor 61 drives the threaded rod 62 to rotate after starting. The threaded rod 62 moves the threaded sleeve 64 of the partition plate 63, so that the partitions in the two distribution bins 3 are arranged in a certain position. At this time, the closing plate 7 is opened at the same time to drop the medicines in the two distribution bins 3 according to a certain proportion, and the medicines are moved along the reserved groove 65 through the fixed plate 66 to prevent the medicines from falling from the fixed plate 66, thereby ensuring that the proportion of the medicines in the two distribution bins 3 does not change.

[0037] See also Figure 2 and Figure 5As shown, a delay structure 8 is provided in the middle of the threaded rod 62 and on one side of the partition plate 1 63, and the delay structure 8 includes a partition plate 2 81, and the partition plate 2 81 is welded to one end of the outer side of the threaded sleeve 64 to ensure that the partition plate 2 81 and the partition plate 1 63 can move synchronously. A gear 1 82 is sleeved on the outside of the threaded sleeve 64 and located between the partition plate 1 63 and the partition plate 2 81, and a gear 3 87 is provided on one side of the gear 1 82. The gear 3 87 and the gear 1 82 rotate synchronously. When the gear 1 82 rotates, it will drive the gear 3 87 to rotate, and the linear speed of the gear 3 87 is less than the linear speed of the gear 1 82, so that the speed of the meshing point of the gear 1 82 is greater than the speed of the meshing point of the gear 3 87, and the partition plate 2 81 is provided with a gear 1 82. A gear 2 86 is provided on the side, and gear 2 86 is meshed with gear 3 87. A tooth plate 2 85 is integrally provided on the upper surface of the closing plate 7. A partition plate 1 83 is provided inside the material distribution bin 3 and above the gear 1 82. A tooth plate 1 84 is integrally provided on the lower surface of the partition plate 83. The tooth plate 1 84 is slidably connected with the inside of the material distribution bin 3. Gear 2 86 is meshed with tooth plate 2 85. Gear 1 82 is meshed with tooth plate 1 84. The telescopic cylinder 10 moves the closing plate 7. The tooth plate 2 85 of the closing plate 7 rotates with gear 2 86. Gear 2 86 drives gear 3 87 to rotate. Gear 3 87 rotates synchronously with gear 1 82, so that gear 1 82 can move the tooth plate 1 84 of the partition plate 83.

[0038] See also Figure 5 and Figure 6 As shown, a reserved groove 89 is provided on the inner wall of the material distribution bin 3 and located at the partition plate 83, and the reserved groove 89 is slidably connected to the partition plate 83. The partition plate 83 can be moved along the inside of the reserved groove 89 under the drive of the gear 82, so as to open or close the partition plate 83. A partition plate 810 is welded inside the material distribution bin 3 and located at the edge of the partition plate 83. The partition plate 810 is located above the partition plate 83, and the upper surface of the partition plate 83 is slidably connected to the partition plate 810. When the partition plate 83 is closed, the partition plate 83 and the partition plate 810 can block the full medicine on it, and the medicine under the partition plate 83 is kept for backup.

[0039] See also Figure 5 and Figure 6As shown, a rotating hole 88 is opened inside the gear 1 82 and the gear 3 87, and the rotating hole 88 of the gear 1 82 is rotatably connected with the tooth plate 1 84. Before welding the partition plate 2 81, the gear 1 82 and the gear 3 87 are first sleeved on the outside of the threaded sleeve 64, and the gear 2 86 and the gear 3 87 are installed on the inner walls of the partition plate 1 63 and the partition plate 2 81. The surface of the closing plate 7 is divided into a smooth surface and a contact surface, and the tooth plate 2 85 is located at the contact surface. There is a gap between the gear 2 86 and the smooth surface of the closing plate 7. The moving direction of the closing plate 7 is the same as the moving direction of the partition plate 1 83. When the gear 2 86 is aligned with the smooth surface of the closing plate 7, the gear 2 86 does not rotate, and when the gear 2 86 contacts the contact surface of the closing plate 7, the gear 2 86 rotates.

[0040] See also Figure 5 As shown, when the cylinder 10 contracts, the gear 2 86 first passes the smooth surface of the closing plate 7 and then cooperates with the contact surface of the closing plate 7. When the gear 2 86 cooperates with the contact surface of the closing plate 7, the partition plate 1 83 moves again. The telescopic cylinder 10 makes the closing plate 7 move toward the cylinder 10. The smooth surface of the closing plate 7 is first aligned with the gear 2 86. At this time, the gear 2 86 will not rotate, and the medicine can first fall from the distribution bin 3 to the inside of the packaging bin 4. When the gear 2 86 contacts the toothed plate 2 85 of the closing plate 7, the gear 2 86 and the gear 3 87 are driven. , gear three 87 drives gear one 82 to rotate synchronously, gear one 82 and tooth plate one 84 of partition plate one 83 are transmitted, so that partition plate one 83 can be closed, thereby isolating the medicine under partition plate one 83, and since the cylinders 10 of the two groups of silos 3 work synchronously, the medicines can be controlled to fall or stop falling at the same time, and through the fit of partition plate two 810 and partition plate one 83, the medicines above the organization sub-silos 3 can be made to fall below the partition plate one 83, avoiding different falling of the medicines inside the two sub-silos 3.

[0041] See also Figure 6As shown, when the cylinder 10 is extended, the contact surface of the gear 2 86 and the closing plate 7 are matched, and the spacer plate 1 83 moves at the same time. After the gear 2 86 and the contact surface of the closing plate 7 are matched, they pass through the smooth surface of the closing plate 7. Since the spacer plate 1 83 and the spacer plate 2 810 are closed, all the medicines under the spacer plate 1 83 can fall down. At this time, the cylinder 10 is extended, so that the tooth plate 2 85 of the closing plate 7 is meshed with the gear 2 86, so that the spacer plate 1 83 moves through the cooperation of each gear. At the beginning, the closing plate 7 can separate the materials. The bottom end of the bin 3 is closed, and the initial movement of the partition plate 83 can be blocked by the partition plate 2 810 to prevent the medicine from continuing to fall into the distribution bin 3 and then into the packaging bin 4. In the later stage, after the closing plate 7 blocks the bottom end of the distribution bin 3, the partition plate 83 is detached from the partition plate 2 810, so that there is no medicine between the partition plate 1 83 and the closing plate 7. At this time, the partition plate 1 83 is detached from the partition plate 2 810 and the medicine above the distribution bin 3 can fall into its space, and the space between the partition plate 1 83 and the closing plate 7 can be filled again.

[0042] It should be noted that each time the medicine needs to be added from the two distribution bins 3 to the interior of the packaging bin 4, the two cylinders 10 are contracted at the same time, so that the closing plate 7 moves along the bottom end of the distribution bin 3. There is a gap between the smooth surface of the closing plate 7 and the gear 2 86, which will not affect the movement of the gear 2 86. The medicine below the partition plate 1 83 leaks out from the bottom end of the distribution bin 3, and the contact surface of the closing plate 7 continues to move to mesh with the gear 2 86, so that the gears mesh with each other until the tooth plate 1 84 of the partition plate 1 83 of the gear 1 82 is meshed, and the partition plate 1 83 moves along the inside of the reserved groove 2 89, so that the partition plate 1 83 contacts the partition plate 2 810, thereby preventing the medicine above the partition plate 1 83 from continuing to leak out, until the medicine at the bottom of the distribution bin 3 leaks out, and then the cylinder 10 is moved. The tooth plate 2 85 on the contact surface of the closing plate 7 is transmitted to the gear 2 86 to close the closing plate 7 at the bottom of the distribution bin 3. The transmission of the gear 2 86 will drive each gear to transmit, so that the gear 1 82 moves the tooth plate 1 84 of the partition plate 1 83. The partition plate 1 83 moves after the movement of the closing plate 7, so that the partition plate 1 83 can be separated from the partition plate 2 810, and the medicine above the distribution bin 3 falls between the partition plate 1 83 and the closing plate 7 again. This is repeated, and the medicine can be dispensed into the interior of the encapsulator 5, and then the medicine can be packaged, and with the cooperation of the quantity adjustment structure 6, the two distribution bins 3 can be dispensed into the interior of the encapsulator 5 according to a certain proportion, and the encapsulator 5 packages the packaging bags of the medicine.

[0043] See also Figure 2 and Figure 7As shown, a knocking structure 9 is provided at the inner corner of the partition plate 1 63, and the knocking structure 9 includes a reserved groove 3 91, and the reserved groove 3 91 is opened at the corner of the partition plate 1 63. A knocking block 92 is rotatably connected inside the reserved groove 3 91, and the knocking block 92 is connected to the partition plate 1 83 through a connecting shaft. A gear 4 95 is rotatably connected between the knocking block 92 and the gear 1 82, and the gear 4 95 is connected to the partition plate 1 83 through a connecting shaft. The gear 4 95 meshes with the gear 1 82, and a connecting rod 93 is connected between the gear 4 95 and the knocking block 92 The connecting rod 93 is located at the end of the knocking block 92, and the two ends of the connecting rod 93 are provided with a connecting column 1 94 and a connecting column 2 96, and the connecting rod 93 is rotatably connected with the connecting column 1 94 and the connecting column 2 96. The knocking block 92 is used to knock on the inner wall of the sub-bin 3. The rotation of gear 1 82 can drive gear 4 95 to rotate, and gear 4 95 can push the knocking block 92 to swing through the connecting rod 93, so that the knocking block 92 can knock on the inner wall of the sub-bin 3, so that the medicine slides along the inner wall of the sub-bin 3 to avoid the medicine adhering to the inner wall of the sub-bin 3.

[0044] See also Figure 7 and Figure 8 As shown, a crank rocker mechanism is formed between the knocking block 92, the connecting rod 93 and the gear four 95. The connecting column 2 96 of the connecting rod 93 rotates around the axis of the gear four 95. The knocking block 92 is in intermittent contact with the inner wall of the distribution bin 3. The rotation of the gear four 95 drives the connecting rod 93 and the knocking block 92 to swing, so that the knocking block 92 can knock the inner wall of the distribution bin 3.

[0045] It should be noted that moving the closing plate 7 can drive the movement of each gear, among which the rotation of gear one 82 can drive the rotation of gear four 95. When gear four 95 rotates, the connecting rod 93 and the knocking block 92 knock the inner wall of the distribution bin 3, and the medicine can fall from the inner wall of the distribution bin 3, avoiding the medicine from adhering to the inner wall of the distribution bin 3.
