Differential feeding needle distance is accurate, the upper roller, lower roller and swing needle are driven by independent stepper motor, and the differential feeding of upper and lower rollers can be set to achieve perfect sewing stitch coincidence;
The stepper motor replaces the traditional mechanical drive and electromagnet drive and controls the backseam structure to achieve the experience of light sound, silent backseam and super-fast sewing.
Free to change the needle distance to solve the fast needle, internal and external bending, thin and thick material, climbing needle distance is consistent, stitch perfect coincidence;
Thread length is only 3mm;
Servo motor direct drive;
Automatic thread cutting, automatic lifting press foot, automatic backstitching;
Roller press foot feed is easy to turn freely when sewing irregular products;
Can realize pattern programming sewing through programming mode;
Electronic keys are used for backstitching, and manual backstitching is added to make the operator more convenient to use;
CNC needle distance adjustment completely solves the problem that the old manual needle distance adjustment is inconsistent with each needle distance.
