四齿轮式卷取机构的纬密分布研究与优化设计

针对织机的四齿轮式连续卷取机构的纬密分布情况,采用VFP语言开发这类织机的纬密分布演示与优化系统.将卷取机构参数输入到此系统中,分析其密度分布规律,找出纬密分布不均匀的原因,得出采用4支变换齿轮的连续式卷取机构.这种机构虽能满足纺织品所需的纬密要求,但不能保证在所有密度区间上连续分布.提出针对棉、毛及亚麻纺织品生产时要...

Research and optimization of four gear continuous take-up mechanism's weft density

With regard to the weft density distribution condition of four-gear continuous take-up mechanism on loom, this study has developed a “weft density demonstration and optimization system” based on VFP. Through inputting the parameters of the take-up mechanism into this system, analyzing the rule of density distribution, and finding out cause leading to uneven distribution of weft density, it concluded that by using 4 transform gears the continuous take-up mechanism can meet the requirements for weft density of fabrics, but it can not guarantee the continuous distribution in all density gradients. It is proposed that for cotton, wool and linen production, different configuration parameters of the gear should be considered. 3 sets of specific and optimized programs for gears more than 17 teeth are presented, in which, at least there is one group of spare gear that consists of 7 only.
