圆纬机上不锈钢纤维纱筒底座的设计

Design of the Yarn Cones Retainer of the Stainless Steel Fiber for Circular Knitting Machine

针对不锈钢纤维在编织过程中不能由纱筒正常退绕的问题,通过分析不锈钢纤维与常规纺织纤维的摩擦性能和纱线毛羽,提出不锈钢纤维摩擦阻力大、纱线毛羽较多会对退绕产生一定影响。并结合金属纤维使用常规纱筒底座时存在的不足,设计一种底座内芯直径可无级调节的纱筒底座,避免不锈钢纱线退绕时的纱筒抖动和掉落等问题,使不锈钢纱线的退绕稳定、退绕条件一致性好,该纱筒底座也可用于其他金属纤维的退绕中,以及其他编织机上。

In terms of the problems of the yarn unwinding during the stainless steel fiber knitting process, this paper describes the influences of the high frictional resistance and more yarn hairiness on the yarn unwinding. Ac- cording to the disadvantages of the conventional cones retainer for stainless steel fiber, it designs a yarn cones re- tainer whose mandrel diameter can be adjusted freely so as to prevent the yarn package from sliding off its holding device, and to maintain the un-winding process steady and consistent. This yarn package retainer can be used in other unwinding stainless steel fiber and knitting machine.
