The divider 7 is driven to rotate by the first motor 9. Four loading molds 12 are evenly arranged on the upper surface of the turntable 5. A second placement groove 121 is formed on the surface of the loading mold 12. The four loading molds 12 divide the turntable 5 into four workstations. The divider 7 drives the turntable 5 to rotate one workstation each time. A feeding and weighing mechanism 4 is arranged on the upper surface of the bottom plate 3. A feeding pipe 17 is arranged at the discharge port of the feeding and weighing mechanism 4. The opening of the feeding pipe 17 is located directly above one of the loading molds 12. A first feeding plate 13 is further arranged on the bottom plate 3. A plurality of packaging boxes 14 are evenly distributed on the first feeding plate 13. One end of the first feeding plate 13 is directly opposite to the opening of the second placement groove 121 of the loading mold 12, facilitating the feeding of the packaging boxes 14 into the second placement groove 121. The other end of the first feeding plate 13 is connected to a feeding vibrating disk for feeding the first feeding plate 13. A pressing mechanism 15 is further arranged on the upper surface of the bottom plate 3. The pressing mechanism 15 is arranged opposite to the first feeding plate 13.

[0028] As Figures 3 to 5As shown, the blanking and weighing mechanism 4 includes a column 41 and a feeding tray 42. The column 41 is arranged on the upper surface of the bottom plate 3, and the feeding tray 42 is arranged on the top of the column 41. A second motor 45 is arranged inside the top of the column 41. A receiving groove 421 is formed on the upper surface of the feeding tray 42. A rotating hole 426 is formed in the middle of the bottom of the receiving groove 421. An installation groove 422 and a first blanking hole 423 are also formed at the bottom of the receiving groove 421. The installation groove 422 and the first blanking hole 423 are respectively located on both sides of the rotating hole 426. A second blanking hole 424 is formed in the middle of the bottom of the first blanking hole 423. A frustum-shaped groove 425 is formed between the bottom of the first blanking hole 423 and the second blanking hole 424. A sorting tray 46 is rotatably arranged in the receiving groove 421. The output end of the second motor 45 penetrates through the rotating hole 426 and is fixedly connected to the bottom of the sorting tray 46, facilitating driving the sorting tray 46 to rotate. A weighing sensor 47 is arranged in the installation groove 422. The upper surface of the weighing sensor 47 abuts against the bottom of the sorting tray 46. A first placement groove 461 is formed in the bottom of the material tray of the sorting tray 46. A movable material tray 48 is rotatably arranged in the first placement groove 461. Rounded corners are formed at the edges of the movable material tray 48. A material groove 481 is formed on the upper surface of the movable material tray 48. A cutting groove 482 is formed at the bottom edge of the material groove 481, facilitating the passage of traditional Chinese medicine granule preparations. A cover plate 43 is arranged on the top of the feeding tray 42. A blanking bin 44 is arranged on the upper surface of the cover plate 43. A switch is arranged at the material outlet of the blanking bin 44 to control the opening and closing of the material outlet. In the initial state, the movable material tray 48 is symmetrically arranged with respect to the weighing sensor 47, and the lower end of the movable material tray 48 abuts against the weighing sensor 47. The weighing sensor 47 transmits the initial detection value to the controller. Traditional Chinese medicine granule preparations are put into the blanking bin 44, and the switch works to open the material outlet. The traditional Chinese medicine granule preparations fall into the material groove 481 of the movable material tray 48. As the traditional Chinese medicine granule preparations in the material groove 481 increase, the value on the weighing sensor 47 becomes larger. When the value of the weighing sensor 47 reaches the preset value, the controller receives this signal and controls the switch to close the material outlet of the blanking bin 44. At the same time, the controller controls the second motor 45 to rotate. The second motor 45 drives the sorting tray 46 to rotate 180°. At this time, the movable material tray 48 is located directly above the first blanking hole 423, and one end of the movable material tray 48 rotates downward. The traditional Chinese medicine granule preparations in the material groove 481 fall into the first blanking hole 423 through the cutting groove 482, and then fall into the packaging box 14 through the frustum-shaped groove 425, the second blanking hole 424 and the blanking pipe 17 for packaging and collection, completing the classification and weighing process. The controller controls the second motor 45 to drive the sorting tray 46 to continue rotating 180°, so that the lower end of the movable material tray 48 abuts against the weighing sensor 47 again, and the switch opens the material outlet to continue feeding. Repeating the above process can continuously classify and weigh the traditional Chinese medicine granule preparations.

[0029] As Figure 6As shown, the pressing mechanism 15 includes a bracket 151 and a second feeding plate 152. The bracket 151 is arranged on the bottom plate 3. A support block 157 is arranged at the bottom of the second feeding plate 152, and the lower end of the support block 157 is arranged on the bottom plate 3. The second feeding plate 152 is located below the middle of the bracket 151. A plurality of box lids 16 are evenly distributed on the second feeding plate 152. One end of the second feeding plate 152 is connected to a feeding vibrating disk, and the feeding vibrating disk is used to uniformly convey the box lids 16 to the second feeding plate 152. A sliding groove 1511 is formed in the side wall of the top of the bracket 151, and a slider 153 is slidably arranged in the sliding groove 1511. A first electric telescopic rod 154 is arranged at the bottom of the middle of the bracket 151, and the output end of the first electric telescopic rod 154 is fixedly connected to the side wall of the slider 153. A second electric telescopic rod 155 is arranged at the bottom of the slider 153, and a suction cup 156 is fixedly arranged at the output end of the second electric telescopic rod 155. The suction cup 156 facilitates grasping the box lid 16 and placing it on the packaging box 14.

[0030] Specifically, the implementation manner is as follows: the controller controls the first motor 9 to drive the divider 7 to rotate, and the divider 7 drives the turntable 5 to rotate one station. The first feeding plate 13 and the second feeding plate 152 respectively convey the packaging boxes 14 and the box covers 16 through the feeding vibrating trays. The first feeding plate 13 conveys the packaging boxes 14 into the second placement groove 121 of the loading die 12. The packaging boxes 14 rotate one station along with the turntable 5, so that the packaging boxes 14 are aligned with the opening of the blanking pipe 17. The controller controls the switch to work and opens the material outlet of the blanking bin 44, and the traditional Chinese medicine granule preparations fall into the material groove 481 of the movable material tray 48. As the traditional Chinese medicine granule preparations in the material groove 481 increase, the value on the weighing sensor 47 becomes larger. When the value of the weighing sensor 47 reaches the preset value, the controller receives this signal and controls the switch to close the material outlet of the blanking bin 44 to complete the weighing. At the same time, the controller controls the second motor 45 to rotate, and the second motor 45 drives the sorting disk 46 to rotate 180°. At this time, the movable material tray 48 is located directly above the first blanking hole 423, and one end of the movable material tray 48 rotates downward. The traditional Chinese medicine granule preparations in the material groove 481 fall into the first blanking hole 423 through the cutting groove 482, and then fall into the packaging box 14 through the conical groove 425, the second blanking hole 424 and the blanking pipe 17 for inner packaging and collection, thus completing the classification and weighing process. The controller controls the second motor 45 to drive the sorting disk 46 to continue rotating 180°, so that the lower end of the movable material tray 48 abuts against the weighing sensor 47 again, and the switch opens the material outlet to continue feeding. Repeating the above process can continuously classify and weigh the traditional Chinese medicine granule preparations. After the packaging box 14 is filled with a fixed amount of traditional Chinese medicine granule preparations, the divider 7 drives the turntable 5 to rotate one more station. The controller controls the first electric telescopic rod 154 to pull the slider 153 to slide so that the second electric telescopic rod 155 is located directly above the box cover 16. The second electric telescopic rod 155 pushes the suction cup 156 downward to suck the box cover 16. After sucking the box cover 16, the second electric telescopic rod 155 resets. The first electric telescopic rod 154 pushes the slider 153 to move, so that the second electric telescopic rod 155 is aligned with the packaging box 14. The second electric telescopic rod 155 pushes the suction cup 156 downward to press the box cover 16 onto the bottle mouth of the packaging box 14 to complete the sealing packaging. The divider 7 drives the turntable 5 to rotate one more station, and the packaged packaging box 14 is taken off and stored. By sequentially completing the above steps, the automatic classification, weighing and packaging process of the traditional Chinese medicine granule preparations can be realized, with convenient and simple operation and high working efficiency.

[0031] In addition, it should be understood that although this specification is described according to the implementation manners, not every implementation manner only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
