多挡快换绕丝机的设计

Design of A Multi-Position Rapid Conversion Winding Machine

目的研究扁丝卷绕螺距及错位距离对丝锭质量的影响,分析传动比与卷绕螺距及错位距离的理论联系,解决生产中针对不同规格扁丝收卷换挡难的问题。方法通过反复实验取得经验数据,并结合理论分析设计多挡快换机构,对编织袋生产线上现有的绕丝机进行大幅度的结构改造。结果改造后的绕丝机从原来1台只能对应1种规格扁丝,通过便捷的换挡操作便可应对多种规格扁丝,生产效率和产品质量都得到显著提高。结论适宜的螺距及错位距离对丝锭卷绕质量至关重要,可通过传动比设计有效控制卷绕螺距及错位距离,满足不同规格扁丝的卷绕质量需要,依此设计的多挡快换机构有效解决了生产实际难题。

To study the influence of by the screw pitch and the Stagger Distance on the spindle of flattended yarn quality,and to analyze the relationship among the transmission ratio,the screw pitch and the Stagger Distance,and to solve the problem of position conversion for different specifications of flat yarn in the production. Empirical data were obtained through repeated experiments,and the mechanism of Multi-Position Rapid Conversion was designed combining theoretical analysis,and the substantial structural transformation was implemented for the winding machine on the production line of plastic woven sack. An old winding machine could only be used by flat plastic yarn of one specification,while the new machine could be used by a variety of specifications through simple position change. The production efficiency and product quality were both significantly improved. Reasonable screw pitch and Stagger Distance were important for the quality of the spindle of the flattended yarn,and they could be effectively controlled by designing the transmission ratio to meet the requirements of different specifications of flat yarn. The practical problems could be effectively solved by the designed mechanism of Multi-Position Rapid Conversion.
