[0033] When the packaging mechanism is in use, the tablets are first placed on the precision measuring disc 7. The angle of the precision measuring disc 7 will cause the tablets to deviate to one side. Then the packaging roll is placed on the outer wall of the bag placing roller 20. One end of the packaging bag roll is pulled out and passes through the support plate 21, the folding ring 22 and the middle part of the heat-sealing clamping plate 31 in sequence to fold the packaging bag. Then, one end of the packaging bag is pulled by the external driving device. Then, the power is turned on and the servo motor 6 is started. The servo motor 6 drives the second bevel gear 5 to rotate, the second bevel gear 5 drives the first bevel gear 4 to rotate, and the first bevel gear 4 drives the limit rod 3 to rotate. When the limit rod 3 rotates When the precision measuring disc 7 rotates, it will drive the precision measuring disc 7 to rotate. When the precision measuring disc 7 rotates, it will drive the leakage hole 8 to rotate. When the leakage hole 8 rotates to the tablets gathered on one side, the tablets will fall into the leakage hole 8. At this time, the precision measuring disc 7 will also drive the vibration protrusion 35 at the bottom to rotate.
