  • the first roller 1 and the second roller 2 are arranged vertically in a corresponding manner as shown in FIG. 2 - FIG. 7 , and when the fibers, the fiber webs or the analogues pass through the first roller 1 and the second roller 2 , the upper surface and lower surface thereof are squeezed by the first roller 1 and the second roller 2 respectively, and the liquid such as the water is rapidly separated from the upper surface and lower surface.
  • the fibers, the fiber webs or the analogues pass through the first roller 1 /the second roller 2 first to be primarily squeezed between the first roller 1 /the second roller 2 and the guiding belt II 4 /the guiding belt I 3 , and the liquid such as the water is squeezed out from the fibers, the fiber webs or the analogues, and then the fibers, the fiber webs or the analogues continuously pass through the second roller 2 /the first roller 1 to be secondarily squeezed between the second roller 2 /the first roller 1 and the guiding belt I 3 /the guiding belt II 4 , and the liquid such as the water is squeezed out from the fibers, the fiber webs or the analogues.
  • the liquid such as the water is gradually separated from the fibers, the fiber webs or the analogues.
  • the present application is applied to the separation of the liquid such as water from the fibers, the fiber webs or the analogues.
  • the guiding belt I 3 is driven by the first driving rollers 5 to rotate; the guiding belt II 4 is driven by the second driving rollers 6 to rotate; and the fibers, and the fiber webs or the analogues are clamped by the guiding belt I 3 and the guiding belt II 4 to move forwards under the relative motion of the two.
  • the liquid such as the water can be separated in one step or gradually separated in multiple steps through the cooperation of the first roller 1 and the second roller 2 and the cooperation of the first roller 1 and the guiding belt II 4 or the second roller 2 and the guiding belt I 3 .
  • the fibers are always in a squeezed state when entering between the guiding belt I 3 and the guiding belt II 4 , that is, the separation of the liquid such as the water is not only limited to the contact position of the first roller 1 and the second roller 2 , but also enlarged to between the first roller 1 and the guiding belt II 4 and between the second roller 2 and the guiding belt I 3 , so that the back absorption of the liquid such as the water caused by the reduction of the pressure can be avoided.
