Abstract
An embroidery machine includes a sewing arm having an upper shaft for providing a driving force, a needle bar support case, which is assembled to a front portion of the sewing arm so as to be laterally movable, a needle bar provided in a needle bar support case, the needle bar having a needle at a lower end thereof and vertically carrying the needle using a rotation driving force of the upper shaft, and a presser foot, which is provided in the needle bar support case so as to be vertically movable, characterized in that each of the needle bar and the presser foot is operated by an individual drive mechanism. The presser foot is separately driven by its own drive source, independent of the drive source of the needle bar.

An embroidery machine, which includes a sewing arm having an upper shaft for providing a driving force, a needle bar support case, which is assembled to a front portion of the sewing arm so as to be laterally movable, a needle bar provided in a needle bar support case, the needle bar having a needle at a lower end thereof and vertically carrying the needle using a rotation driving force of the upper shaft, and a presser foot, which is provided in the needle bar support case so as to be vertically movable, characterized in that each of the needle bar and the presser foot is operated by an individual drive mechanism,
- wherein the presser foot drive mechanism includes:
- a presser foot drive cam, which is fastened to the upper shaft so as to be rotated thereby;
- a presser foot drive cam transmission member, which is coupled with an outer circumference of the presser foot drive cam so as to be rocked thereby;
- a presser foot drive lever, which is connected to the presser foot drive transmission member so as to vertically pivot about a pivot point;
- a presser foot drive link, which vertically reciprocates according to the amount that the presser foot drive lever pivots;
- and a presser foot drive block, which reciprocates along a needle bar guide shaft in cooperation with vertical movement of the presser foot drive link.
