In this embodiment, the fixing shaft 62 is installed at the water through hole 323 in the middle of the rotating table main body 321, is fixedly connected with the rotating table main body 321, and is rotatably connected with the bearing platform 31 through the bearing 37, on one hand, the fixing shaft 62 can connect the bearing platform 31 and the rotating table 32, so that the rotating table 32 can stably rotate relative to the bearing platform 31 for a long time without movement dislocation, and stable proceeding of subsequent pressing and blanking processes is ensured; on the other hand, the liquid medium in the isolation cavity can flow back into the liquid collecting box 61 through the tubular channel of the fixing shaft 62, so that the liquid medium is prevented from being accumulated on the rotating platform 32, the rotating platform 32 does not need to be cleaned after long-time work, the automatic recovery of the liquid medium is realized without any external tool, and the design concept is ingenious. In addition, since the weight of the rotary table 32 can be maintained within a relatively stable range, the rotary drive mechanism can smoothly drive the rotary table 32 to rotate, and the power is abundant.

Further, referring to fig. 14, the upper surface of the rotating table main body 321 is a cambered surface, and the height of the outer side of the rotating table main body is higher than that of the middle part of the rotating table main body, so that a cambered groove is formed on the rotating table 32. The liquid medium in the isolation cavity can flow from the outside to the direction close to the middle water through hole 323 along the arc-shaped groove, so that the flowing performance of the liquid medium is improved, and the recovery efficiency of the liquid medium is improved.

Referring to fig. 14 and 15, the seal assembly includes a first seal ring 381 and a second seal ring 382, and the upper surface of the carrier 31 extends downward to form a first annular groove and a second annular groove, and the second annular groove is located outside the first annular groove; the mounting hole 324 of revolving stage 32 is located the clearance department of first annular groove and second annular groove, revolving stage main part 321 lower surface extends upwards and is formed with third annular groove and fourth annular groove, third annular groove and fourth annular groove pair the setting with first annular groove and second annular groove respectively, first annular groove and the cooperation of third annular groove form first annular, second annular groove and the cooperation of fourth annular groove form the second annular, first sealing washer 381 and second sealing washer 382 clamp respectively in first annular and the second annular, just first sealing washer 381 and second sealing washer 382 all have the plane that contacts with revolving stage 32.

Thus, the first seal ring 381 and the second seal ring 382 are both fixed to the bearing table 31, and when the rotary table 32 rotates, the rotary table 32 is in surface contact with the first seal ring 381 and the second seal ring 382, and the two rotate relatively. Can play fine sealed effect outside mounting hole 324 through first sealing washer 381 and second sealing washer 382, even partial liquid medium flows to the clearance space department between revolving stage 32 and the plummer 31 after passing through mounting hole 324, cooperation through first sealing washer 381 and second sealing washer 382, also can keep apart this partial liquid medium between first sealing washer 381 and second sealing washer 382, prevent that liquid medium from outwards further diffusing away, when having guaranteed plummer 31 cleanliness factor, the loss volume of liquid medium has also been reduced to a certain extent, help guaranteeing the rate of recovery to liquid medium.

Because the first seal 381 and the second seal 382 are located between the wear plate 39 and the rotary table 32, relative friction occurs between the rotary table 32 and the two seals as the rotary table 32 rotates, resulting in some degree of wear of the seals. The pressure spring 36 in this embodiment is always in a compressed state, and after the seal ring is worn, the pressure spring 36 can compensate the wear of the seal ring through elastic deformation, so that the upper end surface of the seal ring can be always abutted against the rotary table 32, thereby ensuring the effectiveness and reliability of sealing.

During the pressing of the material by the profiling unit 4, the partially softened paper material may be separated from the frame 33 through the meshes of the frame 33 and the water permeable holes 311 of the carrier 31, and finally move into the liquid collecting box 61 with the liquid medium.

Thus, when the rotating platform 32 rotates, the rotating platform 32 drives the material-shifting plate 64 to rotate through the fixed shaft 62, and the material-shifting plate 64 pushes the softened paper on the filter screen 63 in the rotating process, so that the softened paper finally falls through the gap of the filter screen 63; an inclined guide groove 631 is further arranged between the filter screen 63 and the collecting box 67, and softened paper materials separated from the filter screen 63 are guided by the guide groove 631 and finally fall into the collecting box 67.

Softened paper on the filter screen 63 can be transferred out in time through the kick-out plate 64, so that the filter screen 63 is prevented from being blocked, and the filtering efficiency of the filter screen 63 is ensured. In addition, because the material shifting plate 64 is fixedly connected to the fixed shaft 62, and the fixed shaft 62 can rotate along with the rotating platform 32, the automatic cleaning of the filter screen 63 can be realized without the help of another power source, the demand for the power source is reduced, and the design concept is ingenious.
