工作原理 The working principle of 多针绗缝机包括相等长度的上升（下降）支撑件，该支撑独立地构造通过独立操作杆上下移动；安装在上升（下降）支撑件上的多个机针，安装在上升（下降）支撑件下的导向件，该导向件设有导向孔，承载机针的机针支撑件经过该导向孔固定在上升（下降）支撑件上。每个支撑杆设有压脚，同时由弹簧弹性支撑。作为替换，缝被机构造成使安装在细长的纵向前，后钩基座上的多个钩分别通过钩支持件固定就位。在这种情况下，通过调节后钩基座的位置，可同时调节后钩支持件。而且，纵向杆安装在机针的前侧上方，以便根据凸轮导向件的操作在向前（向后）方向旋转一定角度。纵向杆设有与机针相同数量的挑线杆，以允许机针容纳缝被的线，该线穿过每个挑线杆，以避免任何断线 The multi-needle quilting machine includes an equal length of uplift (descending) support, which is independently constructed to move up and down independently. Installed on the up (down) supports multiple needle, installation is rising (falling) supports the guide piece, the guide piece is equipped with the guide hole, carrying machine needle needle supports through the guide hole on the up (down) supports. Each support rod is provided with a press foot, which is supported by spring elasticity. As a replacement, the seam is caused by the mechanism to be installed in a thin longitudinal front, and multiple hooks on the back hook are fixed by hook support. In this case, the rear hook support can be adjusted simultaneously by adjusting the position of the back hook base. Also, the longitudinal rod is mounted on the front of the machine needle so that the operation of the CAM guide part will rotate in a certain Angle forward (backward). The longitudinal bar is equipped with the same number of thread poles as the machine needle to allow the needle to hold the thread of the seam, which passes through each pick rod to avoid any breakage
