In the whole process, the water-absorbent resin particle applying mechanism is continuously ensured to scatter the water-absorbent resin particles on the fluffy non-woven fabric instead of the first layer or the second layer of sheet material, so that the water-absorbent resin particles can be ensured to enter the fluffy non-woven fabric in sequence along with the conveying process of the fluffy non-woven fabric towards the flow direction.
The utility model adds a negative pressure conveying mechanism; under the water-absorbent resin particle applying mechanism, a negative pressure conveying mechanism is added, so that after the water-absorbent resin particle applying mechanism spreads the water-absorbent resin particles on the fluffy non-woven fabric, the water-absorbent resin particles can rapidly enter the fluffy non-woven fabric under the driving of negative pressure air, the entering speed is increased, the distance from the water-absorbent resin particles to the inside of the fluffy non-woven fabric is increased under the same production speed and the same conveying path, and the permeability of the water-absorbent resin particles is improved.
