经编纱线张力补偿装置的工作机制

为获得理想状态的经纱张力，通过改变张力弹簧的规格及其安装密度，对织造过程中的纱线动态张力进行测试，探讨不同补偿作用下的经纱张力波动规律，进而研究补偿装置的补偿机制。结果表明：张力补偿装置的使用可补偿纱线张力波动，并且随着补偿装置弹性系数的增大，纱线动态张力的峰值增大；纱线张力波动过大会导致断纱，影响生产效率；弹性系数并非越小越合适，较小的纱线张力会导致纱线张力波动加剧，易产生垫纱困难，导致布面产生漏针等疵点，理想补偿装置的弹性系数应当存在一个合适的范围。

Working mechanism of warp knitting yarn tension compensator

In order to obtain ideal warp tension dynamics, by regulating the tension spring and its tightness settings, based on investigations carried ort on the dynamics od yarn tension during the knitting process, analysis of the warp tension patterns under different compensations, as well as a study of the operation mechanism of the compensation device was carried out. Results show that the use of tension compensation device can compensate for yarn tension fluctuation. However, with the increase in the elasticity coefficient of the compensation device, the peak value of yarn dynamic tension also increases leading to excessie yarn tension variation resulting in yarn breakages which in turns asversely impacts production efficiency. However, it cannot be taken that the lower the elasticity coefficiency the better, as lower yarn tension leads to volatility in yarn tension, leading to peoduction defects such as drop stitches on fabric surfaces. The elastic coefficient of an ideal compensation device, therefore, needs optimum adjustment to ensure efficient production.
