The use of embroidery machines has certain electrical principles. Firstly, using the embroidery CAD software to make a plate, after the sample is generated, the discs containing the embroidery program and the pattern are respectively placed in the computer disk drive, and under the control of the program, the computer replaces the coordinate values of the pattern with the X and Y directions of the stretch frame. The electrical signal with the same amount of displacement is sent to the X, Y, Z single-chip system for motor speed-up and processing, and the three-phase six-beat number is output. The power amplifier box of the line motor is used for power amplification, and the red X and Y stepping motors are driven. The stretch frame completes the feed motion between X and Y; at the same time, the Z stepping motor is driven, and the needle is moved up and down, so that the embroidery continues continuously.

The Z stepping motor drives the head transmission mechanism through a synchronous toothed belt or the like, and the specific mechanism of the head makes the lead mechanism and the needle lead the upper line to make the lower movement, puncture the fabric; the hook of the hook mechanism rotates, so that The upper thread bypasses the bobbin case with the bottom thread; the thread take-up mechanism moves, transports the upper thread, tightens the stitch, and prepares the upper line segment of the next stitch.

The X and Y stepping motors drive the silk frame and fabric for plane movement through a mechanism such as a synchronous toothed belt. The stitches to be embroidered on the fabric are sent to the needle embroidery, and the speed of the needle movement up and down and the direction of the movement of the stretch frame, the amount of movement and the moving speed are coordinated to make the upper thread and the lower thread twist, on the fabric. Make a two-line lock stitch. When the embroidery continues continuously, the computer embroidery of the pattern is completed.
