七、下切刀调整
adjust lower cutter
1、下切刀左右位置调整
adjust left and right positions of lower cutter
进行下切刀调整时应使缝纫机机针处于上停针点，并关闭电控进行手动调试，
手推剪线电磁铁运动通过刀盘驱动连杆带动下切刀组件向左运动（图 1），动刀向左
移动（机头位置）到最左时，，动刀刀 b 尖须超出弯针孔 0.5-1.0mm，定刀下平面
与弯针上平面间隙为 0-0.1mm（图 2），调节下切刀左右位置可松开紧定螺钉 2，
通过调节曲柄 2 左右方向来调节下切刀位置（图 3），
When we adjust lower cutter we need to made needle point in the above
on the sewing machine , and close the electronic control to manual
debug,the movement of hand shear wire magnet is through
the to make
lower cutter component movement to the left (figure 1), At the time of the
moving cutter moves to the far left position (nose position), the point of
moving cutter should be 0.5 -1.0 mm beyond the hole of the looper, distance
between the lower plane of the stationary knife and upper plane of the
looper is 0-0.1 mm (figure 2), Adjusting the left and right position can loosen
the 2,
by adjusting the crank 2 left and right to regulate lower cutter
position (figure 3),
当下切刀组件复位时，下切刀组件刀架与下切刀安装版边缘距离为 4mm（图
4），如上述条件在调节过程中无法同时满足，则需要通过松开调节螺母 1 与调节螺
母 2 来调节剪线电磁铁行程，通过调节电磁铁行程满足上述调节要求，剪线电磁铁
标准行程为 20mm（图 3） 。
