Abstract

An apparatus for lifting the presser foot of an embroidery machine includes an arm having an upper shaft providing a driving force, a presser foot driving cam mounted on the upper shaft, a transmission member coupled to the presser foot driving cam and making an oscillating motion, a presser foot driving lever connected to the transmission member and pivoting around a predetermined pivoting point thereof in a vertical direction, a presser foot driving block reciprocating along a needle bar guide shaft according to an amount that the presser foot driving lever is pivoted and moving the presser foot in a vertical direction, and a presser foot height adjustor, displacing the pivoting point of the presser foot driving lever to adjust a height of the presser foot.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates, in general, to an embroidery machine and, more particularly, to an apparatus for lifting the presser foot of an embroidery machine.[0003]2. Description of the Related Art[0004]Generally, an embroidery machine is a biaxial positioning control machine in which an embroidery stitch frame for fixing fabric undergoes horizontal motion in x-axis and y-axis directions while a needle bar thereof moves up and down.[0005]Since this embroidery machine does needlework while the embroidery stitch frame fixing the fabric is transferred in x-axis and y-axis directions, the precise and constant-speed movement of the embroidery frame has a close relationship to the quality of an embroidered pattern.[0006]Thus, as a source of power for driving the needle bar of the embroidery machine in a vertical direction, a servo motor, an induction motor capable of controlling speed, or the like is used. As the power so...
