[0065] The beneficial effect of the above optional embodiment is that effective conveying during the pill packaging process is achieved through the coordinated arrangement of the main conveying mechanism 51 and the auxiliary conveying mechanism 52 .

[0066] The working principle of this device is as follows: when pills need to be packaged, the pills to be packaged are placed into the funnel, and then two rolls of cellophane 2 are wound around the first fixed shafts 11 of the two cellophane feeding devices 1. The two rolls of cellophane 2 are then passed through the first rotating shaft 12, the second rotating shaft 13, and the second roller 17 of the corresponding cellophane feeding device 1 in sequence, and then pass through the gap between the first roller 14 and the motor wheel 19, and then pass through the corresponding transition shaft 6 and are clamped between the two pressing wheels 82. The two first push rods 411 of the first pressing mechanism 41 extend, and the two heat-sealing plates 412 work to heat-seal the cellophane 2 behind the pill from top to bottom to seal the pill from the back. At the same time, the third push rod 321 extends, and the bent insert 325 is pulled out. A pill passes through the feeding pipe 312 and falls onto the pill conveying trough 343. Then the two first push rods 411 shorten and drive the two heat-sealing plates 412 away from the two cellophanes 2. The two second motors 81 work to drive the two pinching wheels 82 to rotate. At the same time, the two first motors 18 work to drive the two motor wheels 19 to rotate. The two motor wheels 19 cooperate with the two pinching wheels 82 to drive the two cellophanes 2 to move backward. When the rear packaging of the pill moves to the position of the conveying device 5, the telescopic rod 341 works to push the pushing block 342 to move and push the pill between the two cellophanes 2 to the position where the front of the pill is packaged. Then the two first push rods 411 extend, and the two heat-sealing plates 412 work to first heat-seal the cellophane 2 behind the pill from top to bottom to achieve the front packaging of the pill. The first drive motor 514 and the second drive motor 522 are working, and the first conveyor belt 511, the second conveyor belt 521, the two pinching wheels 82 and the two motor wheels 19 cooperate to drive the pills to move to the position of the vacuum suction pressing mechanism 42. The vacuum generators 421 of the two vacuum pressing mechanisms work to suck the cellophane 2 on the left and right sides of the pills and then move them to the position of the second pressing mechanism 71. The second push rod 711 extends to drive the heat sealing head 712 to work so that the heat sealing head 712 cooperates with the heat sealing support 74 to heat-seal the cellophane 2 on the left and right sides of the pills. The second push rod 711 shortens to drive the heat sealing head 712 to retract, and after achieving all-round packaging of the pills, it moves to the position of the shearing mechanism 72. The fourth push rod 721 extends to drive the first cutter 723 and the second cutter 724 to work to cut off the cellophane 2 that encapsulates the pills, and the pill packaging is completed.
