clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 带经纱张力器的机械式送经机构是由摆动后梁式的经纱调节装置,自动送经传动装置和经轴等组成。经纱张力器的作用就是控制送经传动装置,保证同一数量的经纱始终按恒定的张力输出,而不受经轴卷绕直径变化的影响。此外经纱张力器还能迅速地平衡织机梭口出现的任何经纱张力的峰值。作为控制元件,它是用来连续不断地调节摆动后梁1的位置,使作用在摆动后梁上的经纱张力与方型扭力杆2所产生的反作用力之间保持平衡。如图4-7所示。当摆动后梁所受的经纱张力较大时,摆动后梁就下降,通过与之相连的控制机构,加速驱动送经轴,增加送经量;当摆动后梁所受的经纱张力较小时,摆动后梁就上升,通过与之相连的控制机构,慢速驱动或制动送经轴,减少送经量。</p><br style="max-inline-size: 100%;
