[0002] The absorbent core is used to absorb liquid in disposable absorbent products such as sanitary napkins, diapers, and menstrual pants. The absorbent core is made by compounding a carrier layer such as absorbent paper, absorbent non-woven fabric, or plush fiber layer with polymer absorbent particles. The polymer absorbent particles have a good liquid absorption effect. After absorbing liquid, the volume expands several times, increasing the thickness of the composite core. The uneven spreading between the polymer absorbent particles and the absorbent paper, absorbent non-woven fabric, or plush fiber layer will directly lead to different local expansion degrees of the absorbent core after absorbing liquid, making the surface of the sanitary napkin, diaper, and menstrual pants uneven, affecting the feeling of use.

[0027] The material paving structure includes a collecting hopper 17 for receiving and discharging high molecular water-absorbing particles transported from the outside, and a U-shaped material shielding plate 18 for preventing the high molecular water-absorbing particles from splashing and detaching from the operating platform 12 when paving. The upper end damping of the collecting hopper 17 is detachably covered with a cover 19, and the cover 19 is integrally provided with a connection port 20 for connecting an external high molecular water-absorbing particle supply pipe, and the connection port 20 is connected to the inside of the collecting hopper 17, and the U-shaped material shielding plate 18 is fitted and connected with the feeding end of the folding plate 9. In this case, the U-shaped material shielding plate 18 is integrally arranged with the folding plate 9, which is convenient for manufacturing and installation, and at the same time prevents the splicing edge of the U-shaped material shielding plate 18 and the folding plate 9 from scratching the carrier layer.

[0028] The collecting hopper 17 is fixedly mounted on the mounting wall 10, and the lower end of the collecting hopper 17 extends into the U-shaped shielding plate 18. A discharge port 21 perpendicular to the processing direction is provided at the bottom of the collecting hopper 17.

[0029] The material discharge port 21 is provided with a spreading roller 22 for uniform material discharge, and the two ends of the spreading roller 22 are rotatably arranged on both sides of the U-shaped material shielding plate 18 along a direction parallel to the material discharge port 21, and a receiving groove 23 for receiving the polymer water-absorbing particles falling from the material discharge port 21 is evenly opened on the surface of the spreading roller 22, and the receiving groove 23 forms an angle with the central axis of the spreading roller 22, and the opening width of the receiving groove 23 is greater than the width of the material discharge port 21; the mounting wall 10 is provided with a third driving member for driving the spreading roller 22 to rotate, and the third driving member is a third motor 24, and the shell of the third motor 24 is fixedly arranged on the mounting wall 10, and the rotating shaft of the third motor 24 passes through the mounting wall 10 and the U-shaped material shielding plate 18 in sequence and is connected to the spreading roller 22.

The setting of the rotating rod 25 further controls the uniform discharge of the discharge port 21, so that the amount of polymer water-absorbing particles received in the receiving trough 23 is roughly the same. At the same time, the polymer water-absorbing particles can be moved by the rotation of the rotating rod 25, so as to prevent the polymer water-absorbing particles from getting stuck in the discharge port 21 after being wetted and adhering to the surface.
