outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 图2-24所示是单辊直辊式整纬器的示意图,它由三只被动导布辊和一套丝杠升降装置组成。前后两辊的轴承固定在机架上,由于中辊两端的轴承是双列向心球面球轴承,轴承座与丝杆螺母相连接,当借助手轮使丝杆转动时,能在一定范围内调节轴线的位置,使该辊轴线可以发生上下偏移。</p><p style="max-inline-size: 100%;

outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 当发现织物纬纱向左后直线歪斜时(面对进布方向看),转动左端丝杠,使中辊(即整纬辊)的左端下降;或转动右端丝杠,使整纬辊右端升高。这样,纬纱的滞后部分放松或超前部分被拉紧,使纬斜得到纠正。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 仔细分析织物在全幅内经向张力的变化情况,可以进一步了解整纬的物理过程。当整纬辊水平放置时,即与织物纬向平行,经向张力在织物全幅内的分布是均匀的,各经纱的相对运行速度也一致;当整纬辊出现歪斜,如右端高于左端时,织物的经向张力就产生了从右至左的递减,如图2-25所示。织物与辊面的摩擦阻力也发生同样的递减。于是,织物经纱的运行速度发生从右至左递增,即整纬辊左端的经纱速度大,右端的速度小。与经纱相交的纬纱也就出现右端变慢、左端加快的现象。这样,左后直线型纬斜就得到了纠正。图2-26是利用紧布器改装的一种单辊直辊式整纬器。它结构简单,效果颇佳,但只能调整3°以内的直线纬斜。</p><p style="max-inline-size: 100%;

图2-27所示的四辊整纬器是目前国内使用较为普遍的一种。它主要由四根整纬辊和调节机构组成。各整纬辊之间分别依靠双列向心球面球轴承与两组连杆相连。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 如果织物正常运行,则各整纬辊相互平行,织物左右边部在被动导布辊A和B之间的穿行长度相等,如图2-28(a)所示。在织物全幅内的经向张力大小一致。各经纱相对运行速度相等,亦即运行中的经纱各段无相对“超前”或“滞后”的现象。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 当发现纬纱向左后歪斜时,旋动手轮,使丝杆转动,带动连杆D<sub style="max-inline-size: 100%; margin: 0px; padding: 0px; font-size: 12px; overflow-wrap: break-word !important; outline: none 0px !important;">1</sub>&nbsp;、D<sub style="max-inline-size: 100%;

outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 整纬器在安装时应注意保持各辊之间与设备处于平直状态,应保证与织物接触部分平直、光洁无毛刺。要注意轴承润滑,使之转动灵活;使用时应保持各转动部分的润滑,发现尘埃及纤维堆积应及时清除。</p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both;
