The fiber material is conveyed to the obliquely downward along with the first wire roller 41, and the second rubber roller 43 further extrudes the material to continue to dehydrate under the action of the two air springs. The material enters the second wire roller 51 along the material return plate, and the third rubber roller 52 further extrudes the material to continue to dehydrate under the action of the large and small air springs. In the whole dehydration process, the first wire roller 41 and the second wire roller 51 are linked by the driving device 23 to stably convey the material.
