Two drainage coating devices 60 coat the surface of the lower pulp and the upper pulp respectively. The polymer spreading device 70 spreads a polymer water absorbent, such as a water-absorbing resin, on the film of the lower pulp.

[0057] When the polymer spreading device 70 is working, water-absorbing resin can be added into the storage box 71. The water-absorbing resin discharged from the storage box 71 is evenly spread on the film under the action of the swing spreading component 72. The controller receives the water-absorbing resin falling amount information monitored by the infrared sensor 752 and compares it with the set value. When it is less than the set value, the vibration component 73 is triggered, and when it is greater than the set value, the flow regulating component 74 is triggered.

[0058] When the swing spreading component 72 is working, the driving motor 726 drives the rotating disk 727 to rotate, and the rotating disk 727 drives the transmission rod 728 to slide in the annular through hole 725, so that the driving block 724 drives the discharge pipe 721 to swing left and right through the guide rod 723 to achieve uniform material spreading. When the discharge pipe 721 swings, the material lever 722 moves at the discharge port of the storage box 71 to prevent material blockage;

[0059] When the rapping component 73 is working, the rapping hammer 733 raps the pad 731 to vibrate the material storage box 71 to prevent the material from being blocked and to speed up the material discharge.

[0060] When the flow regulating component 74 is working, the execution end of the driving cylinder 742 drives the discharge baffle 741 to move, and the discharge baffle 741 adjusts the size of the discharge port of the discharge pipe 721 to adjust the discharge flow of the material;

[0061] When the puncture device 40 is working, the execution end of the pneumatic cylinder 421 drives the lifting plate 422 to descend, so that the puncture needle tube 423 penetrates the composite paper and enters the needle groove 424 to puncture the film, so that the water-absorbing resin can produce a water-absorbing effect when the product is used. When the puncture needle tube 423 enters the needle groove 424, the air pressure source tube 434 connected to the air storage tank inputs pressurized gas into the second flow channel 433 to remove the waste embedded in the puncture needle tube 423, and the negative pressure source tube 432 connected to the negative pressure tank sucks the first flow channel 431 to remove the waste after passing through the first flow channel 431 and the negative pressure source tube 432.

[0062] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
