横机罗纹线圈长度预测模型

Forecast model for stitch length of rib fabric on flat bed machine

通过观察横机罗纹织物的编织过程,经过分析和推导,建立了预测罗纹织物线圈长度的几何模型,并将在设定条件下编织的罗纹织物线圈长度实测值与预测值进行对比,验证了该模型的可行性。结果证明:横机罗纹织物的线圈长度分别与压针深度和齿口距呈较好的线性关系;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,从而解决所标刻度与压针深度不一致的问题,并确立罗纹织物的线圈长度分别与压针深度和齿口距一一对应关系,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参考。

A forecast model for the stitch length of rib fabric was established based on observation of the knitting process of rib fabric on the flat bed machine and certain assumptions through analysis and deduction.Feasibility of the model was verified by the comparison between the measured and predicted stitch length of the rib fabric knitted under preset conditions.The results revealed that the stitch length of rib fabrics showed a good linear relationship,respectively,with press depth and needle bed gap.According to the model,scale of the stitch cam on the flat bed machine head can be reset,the problem that the scale is not consistent with the needle depth is solved,the corresponding relation between the stitch length of the rib fabrics with the press depth and needle bed gap,respectively,is established,which is convenient for production control,can quickly determine the stitch length,and provides a basis for yarn budget and cost accounting.
