Abstract

The invention provides a cloth dragging device of a sewing machine, belonging to the technical field of machinery. The problems that the existing sewing machine is small in application range, complex in structure, high in manufacturing cost, inconvenient to operate and the like are solved. The cloth dragging device of the sewing machine is arranged at the machine head of the sewing machine; a machine needle is arranged at the lower part of the machine head; the cloth dragging device comprises a fixed cloth dragging wheel assembly which is fixed at one side of the machine needle; a moving cloth dragging wheel assembly is arranged at the other side of the machine needle; and an adjusting mechanism which enables the moving cloth dragging wheel assembly to move back and forth in the horizontal direction so as to approach to or move away from the fixed cloth dragging wheel assembly is arranged between the moving cloth dragging wheel assembly and the machine head. The cloth dragging device of the sewing machine has the advantages of high working efficiency, good sewing quality, wide application range and the like.

Description

technical field [0001] The invention relates to the technical field of machinery, and relates to a cloth mopping device of a sewing machine, in particular to a cloth mopping device of a sewing machine for sewing circular stitching. Background technique [0002] In the prior art, the sewing material is usually pressed by hand when sewing circular sewing objects, and after a short section of sewing, the sewing material is adjusted, and then the sewing is continued. This method is not only inefficient, but also prone to defects such as wrinkles and misalignment of sewing materials. Therefore, it is difficult to meet the needs of industrialized high-efficiency and high-quality production by sewing circular sewing materials in the traditional way. [0003] With the segmentation of the market and the intensive management of the garment industry, a sewing machine is often only used in a specific process to sew specific fabrics. The special sewing machine has played a very good ro...
