[0033] Working principle: After the wrapped core is transported from left to right for a distance of the shaping base plate 5, first, the telescopic device 41 and the ultrasonic vibrator 43 on the ultrasonic component 4 use ultrasonic vibration and rising method to make the lower mold grooves 52 on the top surface of the shaping base plate 5 first press against the bottom surface of the core, and then the motor 643 on the driving component 64 drives the pressing shaft group 641 to press and rotate the pressing wheel 644 180 degrees in three stages. The first stage presses and rotates 120 degrees, and the interval time is 1 second, so that the bottom surface of the coating shaping top plate 7 just drops to press against the top surface of the core. This step is for the preliminary shaping and positioning of the core.

[0034] Then in the second stage, the pressure is rotated 40 degrees, and the interval time is 2 seconds. This step will make the first pressing edge 521, the first pressing column 522, and the middle upper pressing convex edge 523 on the lower mold groove 52 squeeze into the bottom layer 121, and the second pressing edge 721, the middle lower pressing convex edge 722, and the pressing column body 7411 on the coating shaping top plate 7 squeeze into the top layer 122. The main purpose of this step is to squeeze the polymer water absorbent core 123 to the side by ultrasonic vibration, so that there will not be too much polymer water absorbent core 123 accumulated and compacted together in the side collecting groove 124 and the main collecting groove 125 during the final shaping.

[0035] Then in the third stage, the pressing and rotating is performed by 20 degrees, and the interval time is 1 second, so that the shaping bottom plate 5 and the coating shaping top plate 7 perform ultrasonic vibration extrusion and shaping of the bottom layer 121, the top layer 122 and the polymer water-absorbing core 123, and the side collecting grooves 124 are obtained by aligning and extruding each first pressure column 522 with each second pressure column 741, and the main collecting groove 125 is obtained by aligning and extruding the middle upper extrusion convex edge 523 with the middle lower pressure convex edge 722, and the edge sealing of the guide core 12 is obtained by aligning and extruding the first pressure edge 521 and the second pressure edge 721.

[0036] In addition, during the final extrusion process of the second pressure column 741, the glue coating block 742 which is composed of the integrated groove glue coating part 7421 and the groove edge glue coating part 7422 will also be applied to the top layer 122 fabric of the groove of the upper guide groove 1242 to obtain the first reinforcement coating 1243, and the groove edge circle of the upper guide groove 1242 will also be applied to obtain the second reinforcement coating 1244.

[0037] Finally, the pressing assembly 6 rotates 180 degrees in the opposite direction so that the coating shaping top plate 7 rises and resets to be demoulded under the action of each spring 65, and the ultrasonic assembly 4 drives the shaping bottom plate 5 to descend and reset to be demoulded.

[0038] In addition, the use of the flow-guiding core 12 is explained in detail. Due to the longitudinal strip deep grooves formed by the main collecting grooves 125, most of the liquid will be guided into the strip deep grooves. When the polymer absorbent core 123 absorbs and stores liquid and expands, the two sides of the middle part of the top surface of the flow-guiding core 12 will be slightly bulged and deformed, so that the longitudinal strip deep grooves in the middle will not bulge, so that the flow-guiding core 12 will not have a significant squeezing feeling on the middle part of the diaper crotch, and due to the side collecting grooves 124 The effect is to guide the remaining liquid into each side collecting groove 124 and be absorbed by the polymer water-absorbing core 123, and the first reinforcement coating 1243 and the second reinforcement coating 1244 reinforce and shape the upper guide groove 1242, so that the upper guide groove 1242 is not easily blocked due to the expansion and deformation of the top layer 122 fabric, and can also form left and right lateral pulling forces on the main collecting groove 125. This is the key to making the top surface of the guide core 12 only slightly bulge and deform toward both sides.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
