The bottle-stopping cylinder on the bottle-feeding track of the bottle conveying mechanism blocks the bottles conveyed by the upper equipment at the position where the desiccant is filled, waiting for the desiccant to be filled, and the bottle mouth is aligned with the shearing mechanism. The stepper motor drives the bag feeding mechanism to pull the desiccant bag out of the desiccant bag rack. The color mark sensor detects the desiccant bag and controls the bag length. The scissors cut the desiccant bag and put it into the bottle. The conveyor belt of the bottle conveying mechanism The filled desiccant bottles are transported to the next equipment, and at the same time, the desiccant bottles to be filled are replenished to the position where the desiccant bag is filled.
