[0002] The automatic deviation-correcting device can be applied to various types of sewing machines, including industrial and household sewing machines, and can adapt to different types of fabrics, such as cotton and silk. It has a wide range of application value in the clothing manufacturing, home textile production and leather processing industries, as well as in the personal use scenarios of hand-sewing enthusiasts. It provides a plane for supporting and conveying the fabric. It is made of metal with a flat and smooth surface to reduce friction during fabric transportation and can adapt to sewing work of different scales.

[0003] On large-scale garment production lines, automatic deviation-correcting devices are key equipment for improving production efficiency and product quality. When producing shirts, the fabric needs to go through multiple sewing processes, including cutting, sewing the collar, cuffs, and body. Since the fabric is supplied in rolls, it is easy for it to deviate during the feeding process, especially for thin shirt fabrics such as silk and chiffon. The automatic deviation-correcting device can ensure that the fabric can still be accurately fed into the sewing area of the sewing machine at high speeds, meeting the production requirements of high-quality clothing.

[0004] For hand-sewing enthusiasts, automatic deflection correction devices can be used as auxiliary tools when handling fabrics that are more difficult to operate, such as elastic fabrics, textured fabrics, or hand-patchwork works. However, if existing automatic deflection correction devices cannot be installed quickly, a lot of time will be spent on positioning, fixing, connecting, and debugging the device with production line equipment. Every time a production task with a different style or fabric is changed, the deflection correction device needs to be readjusted, which prolongs the equipment debugging time, affects the startup speed of the entire production line, and reduces production efficiency.
