AI Technical Summary
Traditional overlock sewing equipment is difficult to adapt to fabrics of different thicknesses or elasticities, resulting in uneven presser foot pressure, fabric displacement, or uneven overlock stitches.
It adopts a detachable hemming mechanism and a pressure-detecting presser foot mechanism, combined with the sewing machine head, and uses the hemming groove and positioning groove for precise positioning. The pressure is controlled by a pressure sensor and a cylinder, and parameters can be set on the touch control screen to achieve automatic adjustment and detection.
It achieves precise edge locking for different fabrics, improves the accuracy of edge rolling, and avoids fabric damage and unnatural edge locking.
