During the upward movement of the filter plate 16, the uncrushed fibers on the top of the filter plate 16 are pushed upward together, and finally the fibers on the top of the filter plate 16 are crushed and squeezed by the rotating first squeezing plate 18, and finally the crushed fibers are discharged downward through the plurality of filter holes 17.

When the filter plate 16 no longer squeezes the second spring column 41 through the second rotating column 26, the third rotating plate 4 pushes the threaded rotating column 25 downward through the second spring column 41, thereby resetting the threaded rotating column 25 and the second rotating column 26; the overall device improves the stability of the second rotating column 26 during long-term operation.
