[0034] (i) The heating resistor in the hot pressing plate 301 is started, and then the absorbent is slid onto the flip plate 311 through the inclined plate 310. Then the first electric cylinder 203 is started, and the first electric cylinder 203 drives the support mechanism 1 under the pressing mechanism 3 to move through the telescopic end transmission shaft 312. The support mechanism 1 under the pressing mechanism 3 drives the first connecting shaft 306 to move through the second connecting rod 307. The first connecting shaft 306 drives the intermediate shaft 304 to move through the first connecting rod 305. The intermediate shaft 304 drives the hot pressing plate 301 to rotate through the moving block 303, so that the absorbent is hot pressed through the hot pressing plate 301.

[0035] (ii) After the hot pressing is completed, the telescopic end of the first electric cylinder 203 moves in the opposite direction, the first connecting rod 305 drives the fourth connecting rod 309 to move through the third connecting rod 308, the fourth connecting rod 309 drives the transmission shaft 312 to rotate, the transmission shaft 312 drives the shift block 407 to move through the rotating disk 406, the shift block 407 pushes the fixed block 408 to rotate through the rotating block 409, the fixed block 408 drives the second gear 403 to rotate through the fixed disk 404, the second gear 403 drives the rotating shaft 402 to rotate through the first gear 401, the rotating shaft 402 drives the flip plate 311 to rotate, and then the absorbent that has completed the hot pressing falls onto the receiving plate 412, and then the absorbent falls onto the placement plate 503 through the receiving plate 412.

[0036] (iii) The second electric cylinder 507 is started, and the second electric cylinder 507 drives the cutting plate 509 to descend through the vertical shaft 508, and the cutting tool on the lower side of the cutting plate 509 cuts the edge of the absorbent body. When the cutting plate 509 is pressed onto the placing plate 503, the placing plate 503 rotates under the action of the cutting plate 509, and then the cut absorbent body slides along the placing plate 503.
