多针缝纫机跳针问题的调整
多针缝纫机在使用过程中遇到较多的问题是跳针，如果频繁的出现跳针现象将会严重影响产品的质量。
Multi needle sewing machine, there are more problems in the use of skipping is frequent, if skipping phenomenon will seriously affect the quality of products.
首先穿线应正确，不正确的穿线方式将会引起跳针、断线及线迹不合等问题。在线迹美观的前提下，机针线及弯针线应保持最低张力，机针应使用UO113GS 14#～16#。
The first thread should be correct, incorrect threading will cause problems, broken and skipping stitch out etc.. The sewing thread and thread sewing machine should keep the minimum tension under the premise of beautiful online trace, and the machine needle should use UO113GS 14# ~ 16#.
（1）弯针与机针的调节
(1) the adjustment of the curved needle and the needle
直针、弯针安装时应完全插入直针针夹顶部弯针座底部，弯针尖与机针侧面的间隙应保持在0～0.1毫米，弯针退到最后时，弯针尖与机针中心线的距离应保持在2.5～3毫米。机针由下死点上升，弯针开始勾线，当弯针尖与机针中心线重合时，弯针尖应在机针孔上方1.5～2毫米处。
Straight needle, curved needle installation should be fully inserted into the straight needle clip at the top of a curved needle seat bottom bending machine needle tip and side clearance should be maintained at 0 ~ 0.1 mm, curved needle back to the last, bending machine needle tip and the center line of the distance should be maintained at 2.5 ~ 3 mm. The machine needle rises from the lower dead center, and the bent needle begins to hook. When the bending pin coincides with the center line of the machine needle, the bending needle tip should be 1.5 to 2 millimeters above the machine needle hole.
（2）拨线杆的调节
(2) adjustment of thread poking lever
拨线杆应保持平面向上，拨线杆头部活动到达机针中心时，应保证与机针的距离为0.5毫米。当弯针勾住机针线，拨线杆开始拨线时，应仔细调整拨线杆，使其能顺利进入弯针的线环内勾住并拨开弯针线，同时应保证拨线杆与弯针尖头部的间隙在0.1～0.2毫米范围内，实际调整时以刚好不与弯针相碰为宜。
The dial lever should keep the plane up, and when the head of the dial moves into the needle center, the distance between the needle and the needle should be kept at 0.5 mm. When bending the needle hook machine needle, thread rod start dialing line, should be carefully adjusted so that the thread rod can smoothly enter the line curved needle hook ring and push bending needle, and ensure thread rod and the needle head bending clearance in 0.1 ~ 0.2 mm range, the actual adjustment just to collide with the needle bending.
（3）机针线量的调节
(3) adjustment of machine needle quantity
当机针下降到下死点时，使针杆过线钩的眼与线量调节杆平齐。如果希望机针线环大些，应把线量调节杆往上移，反之，则把线量调节杆往下移。
The needle fell to the bottom dead center, the amount of the adjusting rod flush the needle rod through the eye line hook and line. If you want the sewing ring to be larger, the wire lever should be moved upwards, otherwise, the adjusting lever should be moved downwards.
（4）弯针线量的调节
(4) the adjustment of the amount of thread sewing
使用化纤线时，可上下调整弯针线钩的位置，使弯针拨线杆在最下方时与线钩眼的距离为7～8毫米。
When the chemical fiber line is used, the position of the bending needle and thread hook can be adjusted up and down, so that the distance between the bent pin and the wire hook is 7~8 mm at the bottom.
以上几点调整方法仅供读者参考，在维修中应根据实际情况，采用一种或多种方法解决。
The above adjustment methods are for readers' reference only. According to the actual situation, one or more methods should be adopted in the maintenance.
