[0054] The plurality of first driving rollers 5 and the plurality of second driving rollers 6 can form structures with a large space in the guiding belt I 3 and the guiding belt II 4.

Embodiment 8

[0055] The present embodiment has the same setup and working principle with that of embodiment 1, and differs in that: as shown in FIG. 8, a tensioning roller is installed in the loop of the guiding belt, i.e. an upper tensioning wheel 54 and a lower tensioning roller 66 in FIG. 8. The tensioning roller is preferably installed on an axis perpendicular to the guiding belt and moves up and down along an arrow direction marked on the tensioning roller in the axis so as to adjust the tension of the loop of the corresponding guiding belt. The lower tensioning roller 66 can be installed in the middle as shown in FIG. 8 and FIG. 10 and may also be arranged at the lowermost end as shown in FIG. 9.

[0056] A rectifying wheel is arranged in the loop of the guiding belt, i.e. an upper rectifying wheel 53 and a lower rectifying wheel 65 in FIG. 8, FIG. 9 and FIG. 10. The rectifying wheel is preferably arranged in a front section of the loop. In a transfer process of the fibers, the fiber webs or the analogues, along with the rotation of each roller shaft, the deviation phenomenon is likely to occur. In order to avoid the transfer mistake, the rectifying wheel is arranged in the loop of the guiding belt. The rectifying wheel is preferably arranged in the front section of the loop. The rectifying wheel is arranged near the front, so that the subsequent transfer accuracy is guaranteed.

Embodiment 9

[0057] The present embodiment has the same setup and working principle with that of embodiment 1, and differs in that: a least one of the two rollers is connected with a pressurizing mechanism so as to increase the pressure between the two rollers.

[0058] Preferably, the pressurizing mechanism adopts an air cylinder (as shown in FIG. 10; the air cylinder (not shown in the figure) is cooperated with a big arm 16; the big arm 16 is installed between the air cylinder and the corresponding first roller 1; the air cylinder drives the big arm 16 to rise and fall to drive the first roller 1 to move up and down, so that the space between the two rollers is changed, that is, the pressure applied to the fibers, the fiber webs or the analogues between the two rollers is changed), an electromagnetic way, a mechanical way or a similar way to lift the corresponding rollers so as to change the pressure between the two rollers.

[0059] In each of the above solutions, a water tank 8 can also be arranged below the guiding belt II 4 and used to receive the water squeezed from the fibers or the fiber webs. More preferably, the water tank 8 is located in the loop of the guiding belt II 4. With the water tank 8, the environmental pollution caused by the splash of the squeezed water and the secondary pollution of the fibers, fiber webs or analogues can be avoided. When the water tank 8 is arranged in the loop of the guiding belt II 4, it is considered that the guiding belt II 4 may move from the original squeezed position to be below the original squeezed position along with the rotation of the second driving rollers 6, the squeezed and falling liquid such as the water drops onto the guiding belt II 4 and may be carried to the squeezed position again. In order to avoid the secondary dehydration caused by the carrying, the water tank is arranged in the loop of the guiding belt to prevent the water from dropping onto the guiding belt II 4 below the squeezed position, thereby improving the dehydration rate in the entire operation process.

[0060] In each of the above solutions, the guiding belt I 3 and/or the guiding belt II 4 is only used for conveying, and the guiding belt I 3 and/or the guiding belt II 4 may also be provided with a drain mechanism formed by meshes, leakage holes, a water conveying channel or a moisture absorption belt. The guiding belt I 3 and the guiding belt II 4 are cooperated to clamp and convey the fibers, the fiber webs or the analogues. When the drain mechanism is arranged thereon, the overflow of the liquid such as the water from the squeezed fibers or fiber webs can be facilitated, thereby improving the separation efficiency of the liquid such as the water from the fibers or the fiber webs. According to the use requirement, the guiding belt I 3 and/or the guiding belt II 4 may also select a second solution: the guiding belt I 3 and/or the guiding belt II 4 selects a felt structure, a felt-like structure, a Teflon mesh or a steel wire mesh, so that the mangling effect can be improved under an extremely small acting force.

[0061] In each of the above solutions, the first roller 1 and the second roller 2 are arranged vertically in a corresponding manner or in a staggering manner. The first roller 1 and the second roller 2 are main parts for squeezing the fibers, the fiber webs or analogues between the guiding belt and the mesh belt. When 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. When the first roller 1 and the second roller 2 are arranged vertically in a staggering manner, 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. In this way, by virtue of one-time or multi-time squeezing, the liquid such as the water is gradually separated from the fibers, the fiber webs or the analogues.

[0062] 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. When the fibers, the fiber webs or the analogues pass through the first roller 1 and the second roller 2, 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. In this process, 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.

[0063] The above description is further detailed description of the provided technical solutions in conjunction with the preferred embodiments of the present invention. It shall not be assumed that the specific implementation of the present invention is limited to the above descriptions. For those ordinary skilled in the prior art, several simple deductions or substitutions may be made without deviating from the inventive concept of the present invention, and shall all be regarded as falling within the protection scope of the present invention.
