Summary:The invention belongs to the technical field of sewing machines, in particular to a sewing machine feeding mechanism which includes a feed lifting rock shaft and a feed shaft, wherein a feed lifting eccentric gear is arranged on the feed lifting rock shaft; the feed lifting eccentric gear and the feed lifting rock shaft are arranged in an eccentric manner; a connecting rod is eccentrically arranged on the feed lifting eccentric gear; a feed arm is mounted on the feed shaft; the connecting rod and the feed arm are connected through a pin and a feed brace; the feed lifting eccentric gear can rotationally adjust the feed lifting eccentric magnitude around the feed lifting rock shaft. According to the invention, a simple adjusting manner is adopted to adjust the feed lifting height of the sewing machine, so as to adapt to the sewing of fabric with different thickness, can replace the conventional manner that parts are required to be replaced to change the feed lifting height; in addition, the simple adjusting manner is continuous stepless adjustment and has the advantage that the adjustable range is large.
