Heterogeneous animal fiber carding machine

Abstract

The invention discloses a heterogeneous animal fiber carding machine which sequentially comprises an automatic feeder, 2-6 sections of carding machines and an output mechanism. The heterogeneous animal fiber carding machine is characterized in that an air draft net curtain device is arranged between every two adjacent sections of carding machines; the air draft net curtain device comprises a reticular transport curtain which is horizontally installed, a special-shaped air draft cover, an air draft pipe, an air draft pipeline and a negative pressure source; wherein the air draft pipeline comprises a main air channel which is evenly provided with air suction holes and connected with the negative pressure source, and a branch air channel; a main cylinder of the carding machines is provided with 1-4 pairs of working rolls and wiper rolls, and the number of the working rolls and the wiper rolls is reduce progressively from the feeding direction of the carding machine to the output direction; screens are arranged under all the sections of carding machines; the air suction holes are positioned under the screens, and the number of the air suction holes is not less than the that of the sections of the carding machines.

Description

technical field [0001] The invention relates to textile machinery technology, in particular to a carding machine which is mainly used for carding rabbit hair, but can also be used for carding heterogeneous animal fibers such as cashmere, camel hair and yak hair. Background technique [0002] Carding machine is a textile machine used for processing heterogeneous animal hair, including animal hair fibers with mixed fiber thickness such as rabbit hair, cashmere, camel hair and yak hair. Through the processing of the carding machine, the rough hair and impurities in the heterogeneous (animal) hair can be removed, and fine fine hair that can be used for textiles can be obtained, and then spun and processed into high-grade fluff products. Although rabbit hair also belongs to heterogeneous animal fibers, it is required for product style or effect (for example, knitted products processed by carded wool spinning system, due to the existence of coarse hair, and the shrinkage performan...

AI Technical Summary

Problems solved by technology

[0003] In recent years, due to climate warming, the demand for thick and warm rabbit fur knitted sweaters has dropped sharply, while high-end, light and thin products are increasingly becoming a clothing trend. Rabbit fur fiber raw materials are generally finer, but Due to the existence of rough hair, it not only affects the spinning of high-count yarns, but also affects the development of new style products. Therefore, scientific carding and processing of rabbit hair has become a technology that needs to be solved urgently.

Although the carding processing of heterogeneous animal fibers is not a new technology for cashmere and other fibers, compared with cashmere, rabbit hair has lower strength. The texture is loose, the strength is low, and the quality is light (the density of cashmere is 1.3g / cm 3 , while rabbit hair is 1.1g / cm 3 , the fineness of coarse hair and fluff of rabbit hair is smaller than that of cashmere), so carding is more difficult

At present, cashmere carding machines are often used to card rabbit hair. Although it can remove part of the coarse hair and impurities, the length of the rabbit hair fiber is too damaged; some people have also tried to use a modified carding machine to card rabbit hair. The fiber damage is too large, and it takes multiple times of carding to meet the coarseness requirement

In other words, within the scope of the applicant's search, there is no carding machine that is particularly suitable for the characteristics of rabbit hair fibers.
