一种三针锁式线迹平缝机

Three-needle lock stitch seam plaining machine

Abstract

本发明属于缝纫机技术,特别是设计能够形成三针锁式线迹的一种三针锁式线迹平缝机。本发明包括包括下轴(1)、一对斜齿轮(2)、牙架(3)、送料轴(4)、抬牙叉(5)、送布牙(6)、三个同步带轮(7)、同步带(8)、两个张紧轮(9)、左梭架(10)、中梭架(11)、右梭架(12)、左旋梭(13)、中旋梭(14)、右旋梭(15)、针板(16)、针夹(17)、机针(18)、针杆(19)、定位勾(20),其特征是运动输入到平缝机的下轴(1)后,通过一对斜齿轮(2)的啮合带动了左旋梭(13)的旋转,然后通过同步带(8)将三个同步带轮(7)连接,把左旋梭(13)的旋转运动同步传递给了右旋梭(15)和中旋梭(14),当针杆(19)带动装夹着三枚机针(18)的针夹头(17)向下运动时,三个旋梭可以同步勾线,形成三针锁式线迹。
The present invention belongs to the field of sewing machine technology, and is especially one kind of three-needle lock stitch seam planing machine. The three-needle lock stitch seam planing machine includes a lower shaft, a pair of bevel gears, a toothed frame, a feeding shaft, a tooth lifting fork, a cloth feeding tooth, three sync belt pulleys, a sync belt, two tensing wheels and other parts. It features that after the motion is fed to the lower shaft, the bevel gear pair rotates the left rotating shuttle, and the rotation motion of the left rotating shuttle is transferred to the right rotating shuttle and the middle rotating shuttle. When the needle rod drives the needle chuck with three needles to move downwards, the three rotating shuttles hook string simultaneously to form three-needle lock stitch.
