25.压脚交叉提升机构的调节(图 35)/Adjusting presser foot alternate lift mechanism(Fig35)
根据缝料疏松和结实程度的不同,在缝纫
中,对摆压脚、小压脚的交叉提升量,可在一定
的范围内进行适当的调节。在一般的中厚料缝纫
中,摆压脚提升量为 5.5mm 之内,小压脚提升时
为 3.5mm 左右。当其他机构不变的情况下,两压
脚提升量之和基本上是一定值。两提升量的变化
近似于按反比定律变化。即:摆压脚的提升量增
加,则小压脚的提升量就减少。反之也然。
调节方法:旋松偏心轮连杆调节曲柄螺钉
A,按图示向上转动压脚升降前曲柄,摆压脚的提
升量增大,反之,向下转动,小压脚的提升量减
少。但其调节量有一定的范围限调,不宜过大。
调好后,将螺钉拧紧, 用手转动上轮,检查一切
正常后方可使用。
During the sewing, the alternate lift amount can be adjusted according to the nature of material. In general
sewing, the amount of walking foot is 5.5mm,and the presser foot lift amount is 3.5mm.
Method: loosen the screw A. turn presser foot front crank up ward to increase the amount of walking foot.
Turn it downward to reduce the presser foot amount, the range of adjusting amount is not too

在缝纫过程中,要改变摆压脚、小压脚的提
升量,其调节方法是:先将偏心轮连杆螺钉(A)
旋松,然后调节该螺钉与压脚升降轴中心距 B;
如果使摆压脚、小压脚的提升量都增加,则使中
心距 B 调小;反之,则可使提升量都减少。其调
节量也有一定的范围,调节幅度不宜过大,调节
好后,将螺钉拧紧,慢慢转动上轮,检查有无碰
撞现象,一切正常后方可使用。
The lift amount of walking presser foot together
with presser foot can also be adjusted slightly. When
adjust-ting, loosen screw (A) adjust its center
distance B between the screw (A) and the presser
foot lift shaft. The lift amount is increased as to
shorten the center distance B, and the lift amount is
decreased as to widen the center distance B. After adjustment, tighten the nut again.
