product description

1. Industry innovation: integrating the main servo system and auxiliary differential programming system of the whole machine; Easy to install, practical and aesthetically pleasing. 2. Utility model patent: The stepper motor shaft is directly connected to a differential component, thereby completing the action of changing the differential. Due to the elimination of the mechanical transmission components and induction Hall in traditional differential models, the common faults of traditional models are avoided. A step differential adjustment device for flat sewing machines, patent number ZL202122099030.0. 3. The elastic and ultra-thin fabric has smoother and more beautiful stitching. 4. For uneven length of sewn fabrics (such as rolled sleeves), perfect stitching is achieved through differential programming.
