The control system can realize the control of corresponding actions by operating the operation box, select the required pattern, drive the control system of the electric cabinet by analyzing and intelligently processing the pattern, and control the servo motor by controlling the driver; the sensor on the motion trail of the servo motor is used for converting the position of the servo motor into an electric signal and transmitting the electric signal to the control circuit board of the electric cabinet to control the stop and start of the motion of the motor, and the mechanical part needing pneumatic control is controlled by giving an electromagnetic valve signal.

And the motor part comprises a motor driver and a motor.

And a motor control interface on the control circuit board is connected with a motor driver and transmits signals to the motor driver, and the motor is controlled by the driver to act. The motors respectively control the X-direction movement motor, the Y-direction movement motor and the two needle shuttle spindle motors, the X-direction and Y-direction movement motors mainly control the movement of the template, and the needle shuttle spindle motors control a head needle and a shuttle.

The electromagnetic valve is connected with the control circuit board, and the control circuit board transmits an output signal to the electromagnetic valve to control the action of the air cylinder.

The sensor comprises various mechanical position control points, a cylinder limiting point, broken line detection and a template movement position.

The button has power-on and power-off buttons, operation buttons such as a power supply control button and a start stop button, and the button further comprises a inching and frame opening button for controlling the small action of the template and the opening of the electromagnetic valve of the template pressing plate.

The electric control system is connected with the mechanical structure.

When the control is realized, the computer operation box carries out data analysis on the input pattern (namely the shape required to be sewn) and converts the data into data and electric signals which can be recognized by the electric control system.

The electric control system controls the X-direction motor and the Y-direction motor to move according to the converted signals, and controls the patterns required by the two needle shuttle motors.

Coordinating according to the signal of the electric control system to move the XY direction motor to move the template, and sewing by the spindle motor.

The technical scheme is as follows:

1. the novel folding clamp can be finely adjusted according to the size of the pocket.

2. The double-color stitch is neat, the two stitches are parallel, and the stitch steps are the same; the material receiving tool runs along a set track, and the error can reach 0.2 mm.

3. The working speed is as follows: 1200 and 2000 RPM.

4. Double-end single machine realizes double-colored sewing.

5. The single head can be switched on and off according to production requirements.

6. The sewing machine is suitable for light sewing, and has standard hook size (optional: large size).

7. And the automatic backstitch stitch function.

8. The tolerance of the triangle lower hem can reach 1.5 mm.
