Description

Bamboo fiber carding machine Technical Field The invention relates to the technical field of manufacturing of spinning bamboo fibers, in particular to a bamboo fiber carding machine. Background Bamboo fibers are mainly classified into two kinds of bamboo pulp fibers and bamboo fibrils according to processing modes. The bamboo pulp fiber is prepared by chemical pulping and regeneration spinning processes, has regular fiber morphology, uniform length and fineness, low entanglement degree and good spinnability, and becomes a main raw material of current bamboo fiber spinning. However, the chemical treatment process also causes the bamboo to lose the original high strength, natural porous structure and excellent antibacterial and moisture permeability. In contrast, the bamboo fiber is directly separated from bamboo by adopting a physical and mechanical method (such as rolling, stewing, wire separation and the like), and the natural hollow section, microscopic pores, a longitudinal transverse section structure and inherent mechanical and functional characteristics of the bamboo fiber are reserved to the greatest extent, so that the bamboo fiber has excellent performances of moisture absorption, quick drying, antibiosis, deodorization, ultraviolet protection and the like, and is a valuable high-performance natural fiber. However, the natural shape of the bamboo fiber is extremely irregular, the length distribution is wide, the rigidity is large, the surface is rough, and the natural characteristics of the bamboo fiber are easy to intertwine, so that the bamboo fiber is mainly used in products with low requirements on fiber shape such as insoles, filling materials, non-woven fabrics and the like at present, but is difficult to directly use for preparing high-quality and high-count textile yarns, so that how to directly use the bamboo fiber for spinning is always a technical problem facing the industry for a long time and can not be effectively solved. When raw bamboo is used as material to produce bamboo fiber, bamboo is processed in the initial stage of bamboo breaking, finishing, fluffing, fiber opening, softening and other steps to obtain coarse bamboo fiber bundle, which is then fed into the post-treatment steps of carding, combing and other steps. The fiber is interwoven into a dense and difficultly-detached network by virtue of surface friction force, high self-hardness and hooking of a longitudinal transverse section, and is partially formed by loose flocculus, and random and intractable entanglement is still carried out among the fibers. The single fibers are distributed in the fiber bundles completely unordered, have no uniform arrangement direction, are mixed in length and extremely uneven in thickness, have large transverse diameter fluctuation, alternate thick sections and thin sections, and are easy to locally gather. The fiber bundles are extremely unstable in shape and obvious in brittleness, can be restructured and tangled or broken at the thick and thin joint parts and the transverse joint parts by slight external force, cannot keep stable conveying shape, and the natural colloid residues are overlapped with the characteristics of high hardness and transverse joint, so that the bonding force among fibers is further enhanced, and the dispersion difficulty is extremely high. The above characteristics determine that the raw bamboo fiber bundles cannot directly follow the existing carding equipment suitable for bamboo pulp fibers or other natural fiber finished products. Therefore, in order to realize the processing and manufacturing of raw bamboo materials into bamboo fibers which can be used for spinning, special innovative design must be carried out on carding equipment in the process of manufacturing the bamboo fibers. The prior art discloses a patent with the bulletin number of CN101463508A, and the patent relates to a bamboo fiber carding machine, which comprises a feeding mechanism, a carding mechanism, a stripping mechanism and a coiling mechanism which are sequentially arranged, wherein the carding mechanism comprises a large tin Lin Yudao f, four carding areas are arranged at the middle upper part of the large tin, each carding area is provided with a working roller and a stripping roller, and the large tin, doffer, the working roller and the stripping roller all adopt a comb needle type structure. The carding machine is particularly suitable for carding bamboo fibers, can greatly reduce the damage to the fibers, and is proved to be beneficial to the improvement of the quality and the grade of the subsequent fabric finished products by ensuring that the short velvet growth rate of the carded bamboo fibers is less than 1.5% and the non-uniformity rate of the carded bamboo fibers is less than 2%. According to analysis, the carding machine of the patent is used for carding the finished product of bamboo pulp fiber before spinning, and aims to reduce fiber damage and short velvet growth rate and
