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, a step differential adjustment device for flat sewing machines is developed, which avoids the common faults of traditional models. 3. The elastic ultra-thin fabric has smoother and more beautiful stitching, and the thick material sewing and feeding are smoother. 4. According to the different angles of the fabric and the twisting directions of the rolled edges, the control system is set to achieve (deficit/synchronization/surplus) feeding of the upper material, with a natural transition in the arc sewing, achieving smooth and non twisting sewing of the arc hem, and meeting the requirement of no ironing for the product. 5. The servo stepper motor is used to control the capacity of each section, which can automatically remember the number of needles and differential force or manually program and store 20 patterns. One hem arc can be set up to 15 sections, divided into time sections, and the differential force can be automatically adjusted or manually switched to meet all hem process requirements.
