Heterogeneous animal fiber carding device and equipment thereof

Abstract

The invention discloses a heterogeneous animal fiber carding device and equipment thereof. The device comprises a rotary carding roller, wherein a rotary dust cage is arranged on one side of the carding roller, a plurality of air holes are uniformly formed in a cylinder body of the dust cage, an air absorbing cylinder in a still position is arranged in the dust cage, the air absorbing cylinder is provided with an air absorbing passage towards the carding roller, a negative pressure zone is formed between the dust cage and the carding roller by the air absorbing passage, fibers in the carding roller can be continuously absorbed to the rotary dust cage by generated absorbing airflow when passing through the negative pressure zone, and the equipment comprises the carding device for the heterogeneous animal fibers. According to the invention, the way of clothes carding in the prior art is replaced by the way of airflow carding, the length and the surface of villi are effectively protected, and the damage to the villi in the carding process is reduced. By the initial verification, the extraction ratio of the villi is improved about 6%, the fallen crude villi does not need repeated recovering treatment.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a carding device and equipment for heterogeneous animal fibers such as rabbit hair and cashmere. Background technique [0002] The carding machine is a textile machine used to process heterogeneous animal hair, including rabbit hair, cashmere, camel hair, yak hair and other animal hair fibers with mixed thickness. The processing of the carding machine can remove the heterogeneous hair The coarse wool and impurities in the fiber can be removed to obtain the fineness fluff that can be used for textiles, and then weaving and processing into high-grade fluff products. At present, carding machines mainly include roller carding machines, flat carding machines and roller flat carding machines. The roller carding machine is equipped with upward, downward or full-circumference working rollers and depilling rollers around the large cylinder. The flat type carding machine is divided into o...

AI Technical Summary

Problems solved by technology

In the prior art, cashmere carding machines are often used to card rabbit hair. Although part of the coarse hair and impurities can be removed, the length of the rabbit hair fiber is too damaged.

Especially in the carding process, the length and surface damage of heterogeneous animal fibers and other fibers is very serious by pure carding. The short-lint rate is above 25%, and it takes 3-16 times of carding to meet the coarseness requirement. Moreover, the average down content in coarse hair is between 15% and 30%, which needs to be recycled repeatedly, which increases the cost of recycling down.
