环锭纺细纱机导纱动程的探讨

探讨加大环锭纺细纱机导纱动程的可行性。分析了环锭细纱机导纱动程的作用及制约因素,对须条在胶辊表面不同位置时胶辊握持力进行了测试分析,并在7个品种上进行了导纱动程从传统的6mm～9mm加大到15mm～18mm的对比试验。结果表明,适当加大导纱动程,不会影响成纱质量,且可以延长胶辊使用寿命,一个复磨周期延长3个月～4个月。要精心做好导纱动程调整工作,并注意将导纱线速度控制在4mm/min以内。

Discussion of Ring Spinning Frame Guiding Travel

Feasibility of increasing ring spinning frame guiding travel was discussed. Function and restraining factors of ring spinning frame guiding travel were analyzed. Gripping force of rubber-covered roll was tested and analyzed as fiber strand laid in different rubber-covered roll surface position. Guiding travel was contrasted and tested on seven products from 6 mm～9 mm to 15 mm～18 mm. The result shows that yarn quality will not be effected when guiding travel is increased properly,while rubber-covered roll lifetime could be extended,one re-regrinding period could be extended 3 to 4 months. Guiding travel adjustment should be done carefully and guiding linear speed should be controlled under 4 mm/min.
