本文从需线量、挑线杆的供线量和收线情况等角度出发,利用数值计算综合法,综合锁式线迹缝纫机的挑线机构。利用此综合出的四连杆挑线机构,其挑线孔的连杆曲线宽度可在预定的范围内,能精确地达到要实现点的(四点或多点)的需线量以降低面线张力,使线缝平直,这对高速缝纫机挑线机构的设计尤为重要。
This article from the need for the amount of thread take-up for the amount of thread and take the line of view from the point of view, the use of numerical synthesis method, integrated lock stitch sewing machine mechanism. With this integrated 4-bar take-up mechanism, the line width of the take-up line connecting rod can be within a predetermined range and the amount of need to achieve a point (four or more points) Line tension, the seam straight, which is particularly important for the design of high-speed sewing machine thread take-up mechanism.
