Abstract

A presser foot lifting device for an embroidery machine, comprising: an arm with an upper shaft providing a driving force; a presser foot transmission cam installed on the upper shaft; a transmission part, which is combined with the presser foot transmission cam and operates Swing movement; presser foot drive rod, which is connected with the transmission part and rotates around its predetermined rotation point in the vertical direction; presser foot drive block, which moves along the needle bar guide shaft according to the rotation amount of the presser foot drive rod a reciprocating motion, and moves the presser foot in a vertical direction; and a presser foot height adjuster, which moves a rotation point of the presser foot driving rod, thereby adjusting the height of the presser foot.

Description

technical field [0001] The present invention generally relates to embroidery machines, in particular to a presser foot lifting device for embroidery machines. Background technique [0002] Generally, an embroidery machine is a two-axis positioning control machine, in which, while the needle bar moves up and down, the embroidery stitch frame for fixing the fabric moves horizontally along the X-axis and Y-axis directions. [0003] Since the embroidery machine performs embroidery work while conveying the embroidery stitch frame for fixing the fabric along the X-axis and Y-axis directions, the precise and constant speed movement of the embroidery frame is closely related to the quality of the embroidery pattern. [0004] Therefore, a servo motor, an induction motor, or the like capable of controlling the speed is used as a power source for driving the needle bar of the embroidery machine in the vertical direction. In particular, a stepping motor, which ensures good positioning ...
