Cloth conveying mechanism of sewing machine

Abstract

The invention discloses a cloth conveying mechanism of a sewing machine. The mechanism is characterized in that the mechanism comprises a riding wheel, a driven wheel, a lifting operation mechanism which controls the riding wheel to rise and descend and a swinging operation mechanism which controls the riding wheel to rotate, the driven wheel is rotatably located on a machine table of the sewing machine, when the riding wheel rises, the riding wheel is separated from the driven wheel, and when the riding wheel descends to a place, the riding wheel abuts against the driven wheel in a transmission mode; the lifting operation mechanism comprises a riding wheel base used for locating rotation of the riding wheel, a supporting rack used for supporting the riding wheel base to rise and descend and slide and a first air cylinder which is in linkage with the lifting movement of the riding wheel base; the swinging operation mechanism transmits the main axis power of the sewing machine to the riding wheel through a linkage component in a linkage mode and drives the riding wheel to rotate. According to the cloth conveying mechanism, the swinging operation mechanism drives the riding wheel to rotate in a linkage mode, the lifting operation mechanism controls the riding wheel to rise and descend, accordingly constant-speed and stable conveying of cloth are achieved, and the sewing effect and quality are effectively guaranteed.

Description

technical field [0001] The invention relates to the field of sewing machines, in particular to a sewing machine cloth conveying mechanism. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. In the sewing process of existing sewing machines, it is still necessary to manually complete the conveying of the cloth. Since it is difficult to grasp the conveying speed manually, it is easy to cause the sewing pitch to be too large or too small, which affects the sewing effect and quality. For this reason, remain to improve existing sewing machine cloth conveying mechanism. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings, the object of the present invention is to provide a sewing machine cloth conveying mechanism in the field, so as to solve the technical problems that the existing sewi...
