AI Technical Summary
Technical Problem
[0003]上述提升过程中，无锁止功能，主轴转动至120°时，梭口全开，引纬器进行穿纬，后续120°-240°的过程中，提刀必须持续对竖针进行托举，来让经纱停在高位保持不动，240°以后，提刀才开始下降，闭合梭口；整个过程中，提刀需要承受的受力时间与受力行程都较长，容易增大提刀损坏的可能，缩短提刀的使用寿命
Benefits of technology
通过设置锁止块与定位件，利用锁止块上的定位结构能够实现提综钩的高度锁定，使提刀能够提前下降执行下一次的开口动作，从而缩短提刀的受力行程和受力时间，延长提刀的使用寿命，使电机峰值扭矩下降，车速上限提高，以此解决传统提升机构中，提刀等待时间较长的问题；
