Problems solved by technology

[0003] When the existing sewing machine sews folded cloth, the surface of the cloth is uneven due to the folding, that is, the folded part is higher than other parts of the cloth. During the sewing process, when the cloth enters the pulling device of the sewing machine Between the pad and the needle pad, since the pulling device has only one pulling roller, the pressure of the pulling roller on the fabric is insufficient when passing through the folded part. Since the fabric is a soft material, this can cause the fabric to deform, such as stretching Or wrinkled, which will also cause this part of the fabric to pass through the gap between the pull roller and the needle pad, resulting in uneven sewing stitches or deviations in the stitches

Abstract

The invention relates to the technical field of sewing machines, in particular to a sewing machine characterized by smooth cloth feeding. An auxiliary pulling roller is added between a tensioning roller and a pulling roller; the auxiliary pulling roller is positioned slightly higher than the pulling roller, so that the gradient of a pulling belt of the portion can be reduced and the contact area between the bottom pulling belt and folded cloth is increased to increase the grabbing force applied to the cloth by the bottom pulling belt. Thus, the speed in the process of moving uphill and downhill of the pulling belt of the portion can be kept uniform, stable cloth feeding is realized, greater grabbing force to folded cloth is guaranteed and smooth sewing and uniform and beautiful stitches are guaranteed.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine with smooth cloth feeding. Background technique [0002] The sewing machine is an elbow-shaped cylinder type, which is used for lap sewing of men's clothing, women's clothing, casual clothing, denim clothing, shirts, overalls, raincoats, etc. [0003] When the existing sewing machine sews folded cloth, the surface of the cloth is uneven due to the folding, that is, the folded part is higher than other parts of the cloth. During the sewing process, when the cloth enters the pulling device of the sewing machine Between the pad and the needle pad, since the pulling device has only one pulling roller, the pressure of the pulling roller on the fabric is insufficient when passing through the folded part. Since the fabric is a soft material, this can cause the fabric to deform, such as stretching Or folded, which will also cause this part of the fabric to pass ...
