[0024] See also Figure 1-2 A rotating wheel 22 is installed in the middle of the outer surface of the two first rotating rods 21, and a belt 23 is sleeved between the two rotating wheels 22. The belt 23 is fixedly connected to the bearing platform 31, and the fixed rod 24 is fixedly connected to the outer surface of the mounting frame 1. A first servo motor 25 is installed inside the fixed rod 24, and the output shaft of the first servo motor 25 is fixedly connected to one of the first rotating rods 21. Sleeve rods 26 are installed on both sides of the interior of the mounting frame 1, and the two sleeve rods 26 are slidably connected to the bearing platform 31.

[0025] The first servo motor 25 drives the first rotating rod 21 to rotate the belt 23 , so that the supporting platform 31 moves along with the belt 23 , thereby ensuring that the sealing device 4 always stays in a straight line during sealing.

[0026] See also Figure 1-4 The screw rod 51 is rotatably connected to the side arm 32, and a first bevel gear 52 is installed on the outer surface of the screw rod 51. A threaded block 53 is threadedly installed on the outer surface of the screw rod 51, and the threaded block 53 is fixedly connected to the mounting box 61. The second rotating rod 54 is rotatably connected to the side arm 32, and a turning handle 55 is installed on one side of the outer surface of the second rotating rod 54. A second bevel gear 56 is installed on one end of the outer surface of the second rotating rod 54, and the outer surface of the second bevel gear 56 is meshed with the first bevel gear 52.

[0027] By rotating the handle 55, the second rotating rod 54 drives the second bevel gear 56 to rotate. Since the second bevel gear 56 is meshed with the outer surface of the first bevel gear 52, the first bevel gear 52 can drive the screw rod 51 to rotate. Due to the limitation of the side arm 32, the threaded block 53 can move horizontally on the outer surface of the screw rod 51, thereby adjusting the height of the clamping structure 6 corresponding to the packaging bag.

[0028] Working principle: when a packaging bag sealing device is used, in the initial state, first, the medicine packaging bag is placed flat on the supporting platform 31. At this time, by turning the handle 55, the second rotating rod 54 drives the second bevel gear 56 to rotate. Since the second bevel gear 56 and the outer surface of the first bevel gear 52 are meshed with each other, the first bevel gear 52 can drive the screw rod 51 to rotate. Due to the limitation of the side arm 32, the threaded block 53 can move horizontally on the outer surface of the screw rod 51, thereby adjusting the height corresponding to the clamping structure 6 and the packaging bag. After adjusting the height, The second servo motor 63 is driven so that its output shaft drives the spur gear 64 to rotate. Since the outer surface of the spur gear 64 is meshed with the toothed bars 66 on both sides, when the toothed bars 66 rotate, the two clamping claws 67 can be driven to move inward, so that a corner of the packaging bag can be clamped and fixed. At the same time, the sealing device 4 starts to heat and seal the packaging bag. At the same time, the first servo motor 25 is driven to drive the first rotating rod 21 to rotate the belt 23, so that the support platform 31 can follow the movement of the belt 23, so that the opening of the packaging bag can be completely sealed.
