Description

Technical Field

[0001] This utility model belongs to the field of nonwoven machinery technology, specifically relating to a fiber cotton web layer degassing, compaction and impurity removal device. Background Technology

[0002] As is known in the industry, because the cotton web produced by a carding machine is relatively loose, if it is directly conveyed from the conveyor curtain to the subsequent web-laying machine and laid into a fiber web preform of the required weight without compression or other technical means, a series of problems will arise, not limited to those described below: the fibers contain a large amount of air, and the fibers are mainly in a physical or mechanical hook-and-loop state, making the connections between fibers very weak, exhibiting a "loose" and "floaty" appearance with almost no strength; excessive short fiber impurities will affect the overall quality of the fiber web; nonwoven products produced by hydroentangling, needle punching, or oven setting will have higher impurity content, affecting product quality. The aforementioned problems are particularly prominent for carding machines that can simultaneously card upper and lower layers, or even upper, middle, and lower layers of cotton web.

[0003] As explained above, the aforementioned process of venting, compacting, and removing impurities from the fiber web layer exiting the carding machine before supplying it to the subsequent web-laying machine has at least the following positive effects: air removal increases fiber web density and cohesion; removal of impurities and short fibers improves product purity and quality; improves fiber web uniformity; provides stable and reliable input conditions for the web-laying machine; and ultimately enhances the quality grade of nonwoven products. However, no publicly available patent or non-patent literature to date has provided technical information that adequately and comprehensively reflects the aforementioned technical effects. The technical solution described below arose in this context. Utility Model Content
