给棉方式对高产梳棉机刺辊梳理效果的影响

针对新型高产梳棉机采用顺向给棉方式生产细绒棉产品,梳棉机产量不高、刺辊区落棉率高、除杂效果不够理想、生条和成纱质量指标不佳等问题,通过分析顺向给棉和逆向给棉的优缺点,并在同型号梳棉机上分别采用顺向给棉和逆向给棉2种形式进行梳棉,对比给棉方式对高产梳棉机刺辊梳理效果的影响,验证了给棉方式对高产梳棉机纺精梳纯棉纱和普梳纯棉色纺纱的影响。结果表明:逆向给棉方式可提高梳棉机产量,提高给棉与刺辊之间的分梳能力,降低落棉率,提高落棉含杂率,减轻锡林周围主分梳区的分梳、除杂负担,提高生条和成纱质量,提高梳理器材的使用寿命,尤其对生产以细绒棉为原料的本色纱和色纺纱具有优势。

Effect of feeding forms on carding efficiency by licker-in roller of high yield carding machine

For the new type of high yield flat carder, with the problems of low output,high noil rate, low noil impurity rate and poor quality of sliver and yarn of the medium cotton production, which is produced in the form of forward feeding. The advantages and disadvantages of forward and reverse feeding form were analyzed. For the same type of carding machine, two kinds of feeding forms were used respectively to compare the influence of feeding form on the carding effect of high yield carding machine. Experiments were carried out to verify the effect of feeding form on combed cotton yarn and color spun cotton yarn. The results show that reverse feeding can increase carding machine output, and improve the carding ability between feeding and licker-in roller, and reduce noil cotton rate, and improve noil cotton impurity rate. The carding and impurity removal burden in the main carding area around cylinder is reduced. The quality of sliver and yarn has been improved. The service life of carding equipment has been extended. The advantages of reverse feeding of carding machine are especially for the production of medium cotton yarn and color spun yarn.
