Mangling device for fibers, fiber webs or analogues

Abstract

Disclosed is a mangling device for fibers, fiber webs or analogues, which comprises two rollers and two conveying mechanisms. At least one of the two rollers is a driving roller. The conveying mechanism comprises at least one driving roller, a plurality of carrier rollers and guiding belts installed on the driving roller and the carrier rollers in a tensioning manner. A space which is used for the fibers, the fiber webs or the analogues to pass is arranged between the two guiding belts, and the portions of the two guiding belts forming the passing space of the fibers, the fiber webs or the analogues are parallel to each other. The two rollers are respectively installed in positions corresponding to the passing space of the two guiding belts.

We claim: 
     
         1 . A mangling device for fibers, fiber webs or analogues, comprising rollers and conveying mechanisms, wherein
 the conveying mechanism comprises an upper conveying unit and a lower conveying unit, and the upper conveying unit and the lower conveying unit are cooperated to clamp and convey the fibers, fiber webs or analogues;   the rollers comprise upper rollers and lower rollers; at least one of the upper rollers and lower rollers is a driving roller; and the upper rollers and the lower rollers compress the upper conveying unit and the lower conveying unit respectively so as to squeeze out liquid in the fibers, the fiber webs or the analogues.   
     
     
         2 . The mangling device for the fibers, the fiber webs or the analogues according to  claim 1 , wherein the upper conveying unit and the lower conveying unit both comprise at least one driving roller, a plurality of carrier rollers and guiding belts installed on the driving roller and the carrier rollers in a tensioning manner, the upper rollers are installed in a loop of the guiding belt of the upper conveying unit; the lower rollers are installed in a loop of the guiding belt of the lower conveying unit; a space for the fibers, the fiber webs or the analogues to pass is formed between the guiding belt of the upper conveying unit and the guiding belt of the lower conveying unit; and the upper rollers and the lower rollers squeeze the guiding belts so as to squeeze out the liquid in the fibers, the fiber webs or the analogues. 
     
     
         3 . The mangling device for the fibers, the fiber webs or the analogues according to  claim 2 , wherein at least one of the guiding belts is provided with a drain passage, and the drain passage is preferably leakage holes, a water conveying channel or a moisture absorption belt; or the guiding belt is set as a felt structure or a felt-like structure. 
     
     
         4 . The mangling device for the fibers, the fiber webs or the analogues according to  claim 1 , wherein at least one of the two rollers is connected with a pressurizing mechanism to increase the pressure between the two rollers. 
     
     
         5 . The mangling device for the fibers, the fiber webs or the analogues according to  claim 4 , wherein the pressurizing mechanism adopts an air cylinder, electromagnetic, mechanical or similar ways to lift the corresponding roller so as to change the pressure between the two rollers. 
     
     
         6 . The mangling device for the fibers, the fiber webs or the analogues according to  claim 1 , wherein a water tank is arranged below the upper conveying unit and/or the lower conveying unit. 
     
     
         7 . The mangling device for the fibers, the fiber webs or the analogues according to  claim 1 , wherein the upper roller and the lower roller are arranged vertically in a corresponding manner or in a staggering manner. 
     
     
         8 . The mangling device for the fibers, the fiber webs or the analogues according to  claim 2 , wherein a tensioning wheel is installed in the loop of the guiding belt. 
     
     
         9 . The mangling device for the fibers, the fiber webs or the analogues according to  claim 8 , wherein the tensioning wheel is preferably installed on an axis perpendicular to the guiding belt and moves up and down along the axis so as to adjust the tension of the loop of the corresponding guiding belt. 
     
     
         10 . The mangling device for the fibers, the fiber webs or the analogues according to  claim 1 , wherein a rectifying wheel is arranged in the loop of the guiding belt; and the rectifying wheel is preferably arranged in a front section of the loop.
