The utility model provides a foot pressing device of a sewing machine, which belongs to the technical field of a sewing machine, in particular to a foot pressing device for a sewing machine. The technical problem solved is that when sewing folded fabric, the cloth height is not uniform, and it is impossible to adjust the secondary presser solely for single side high or low cloth, so that the pressure is not balanced and the feeding is not smooth. A sewing machine foot pressing device includes a main foot pressing component, the side movement of the main foot pressing component is provided with an auxiliary foot, and the main foot pressing component is also provided with an elastic adjusting member which can move along the height direction of the sewing machine. The elastic adjusting member is connected with the auxiliary foot by an elastic member. The device has simple structure, and the height of the auxiliary presser foot can be raised to facilitate feeding. The pressure of the auxiliary presser foot can be adjusted to suit the folding fabric separately, so that the folding fabric with different height can have balanced pressure and improve the smoothness of feeding. The pressure of auxiliary pressure foot can increase the smoothness of thick material feeding.

技术介绍
缝纫机是纺织品加工行业必不可少的设备之一,随着人们对服装及纺织品越来越高的要求,裁剪越来越精细。缝纫机为了满足不同的服装工艺,会设计出不同的压脚。目前市场上的缝纫机的压脚为了满足针织弹性布料线迹美观,特别的设计出带有副压脚的压脚。副压脚在扭簧的作用下可以实现与主压脚的互不干涉的运动。目前副压脚的设计为压力不可调节的,在做厚料时,由于扭簧的作用副压脚处于低位,这样会挤占上料区间,导致厚料上料不易(公告号为CN200999289的一种缝纫机压脚)。做厚料时需要较大的压脚压力送布,目前共有四排牙齿送料,其中两排与副压脚接触,两排与主压脚接触,由于为适应薄料扭簧力较小且不可调节,所以副压脚的压力较小且不可调节,进而导致厚料送料不畅。当缝制折叠布料时导致布料高低不一,无法针对性的对单边高位或低位布料进行副压脚的单独调节,以至于压力不均衡送料不顺畅。
技术实现思路
针对现有技术的不足,本技术提供一种缝纫机压脚装置,解决的技术问题是缝纫机压脚在加工折叠高低不平的布料时,副压脚不能单独调节压力适应折叠布料 ...
