横机平针线圈长度预测模型

Forecast Model of the Stitch Length for Plain Fabric on the Flat Machine

通过观察横机平针组织织物的编织过程,在一定假设的基础上,经过分析和推导,建立了预测平针组织织物线圈长度的几何模型,并通过在设定条件下编织出的平针组织织物线圈长度的实测值与预测值的对比研究,验证了该模型的可行性,在模型的验证中发现,横机平针组织织物的线圈长度与压针深度呈较好的线性关系.根据所建模型,可以对普通横机机头上成圈三角位置的刻度重新进行设置,解决了所标刻度与压针深度并不一致的问题,并确立平针组织织物的线圈长度分别与压针深度的线性关系,既方便于生产时的调节,又能快速确定线圈长度,为生产用纱预算及成本核算提供了依据.

Based on the observation and analysis, a forecast model was presented for the stitch length of plain fabric knitted on the flat machine. Feasibility of the model was verified by the comparison between the measured and predicted stitch length of the plain fabric under the setting conditions. The results revealed that the stitch length of plain fabrics showed a good linear relationship with descent of needle. According to the model, the relationship between the stitch length with the descent of needle was established. Scale of the stitch cam on the flat machine head can be reset, which provide a way to quickly control the stitch length and a foundation for yarn budget and cost accounting.
