Advantages: (no oil dry and wet separation of the head)

1. Industry Innovation: Integrates the main servo system of the entire machine and the auxiliary differential programming system into one; featuring simple installation, practicality and an elegant appearance.

2. Utility Model Patent: A stepping differential adjustment device for lockstitch machines. The stepper motor shaft is directly connected to the differential components to achieve differential adjustment. By eliminating the intermediate mechanical transmission parts and Hall sensors in traditional differential models, it avoids frequent failures of conventional models.

3. When sewing elastic ultra‑thin fabrics, the stitches are flatter and more attractive; when sewing thick fabrics, the feeding is smoother.

4. For sewing fabrics of unequal lengths (such as sleeve gathering), perfect stitching can be achieved through differential programming.

5. A servo motor is used to control the allowance amount of each segment, with 9 segments adjustable by time and section.

Function and configuration:

1.Intelligent digital integrated electronic control, easy to operate.

2.reverse pin switch and operation panel differential momentum adjustment, can be set 9 segments Differential mode, time division.

3.The head is completely oil‑free (note: no white oil imported high temperature resistant solid grease lubrication): picking rod, needle rod, needle rod sleeve, needle rod slider and slide block groove, differential lifting CAM, differential feeding swing shaft sleeve, all adopt micro‑oil technology.
