Mechanical and Electrical Principles of Embroidery Machines

First, use embroidery CAD software to make a pattern. After generating the pattern, place the disc containing the embroidery program and patterns into the computer disk drive. Under program control, the computer replaces the pattern coordinate value with an electrical signal equivalent to the displacement in the X and Y directions of the tension frame, and sends it to the X, Y, and Z single-chip machine systems for motor speed adjustment. After that, output a three-phase six beat signal. The power amplifier box of the wire motor amplifies the power, and the X and Y stepper motors are supported in red, Drive the tension frame to complete the feed motion between X and Y; Simultaneously driving the Z-stepper motor, the needle moves up and down, allowing embroidery to continue continuously.
The Z-stepper motor drives the transmission mechanism of the machine head to rotate through synchronous toothed belts and other means. The specific mechanism of the machine head causes the lead mechanism and the needle head to move downwards and downwards along the surface line, piercing the fabric; The rotary shuttle in the hook mechanism rotates, causing the surface thread to bypass the shell of the hidden bottom thread shuttle; The thread picking mechanism moves, transports the surface thread, tightens the thread trace, and prepares the surface thread segment for the next thread trace. X. The Y-stepper motor drives the flat movement of the silk frame and fabric through mechanisms such as synchronous toothed belts. Send each stitch point on the fabric to the machine needle for embroidery. The speed of the machine needle's up and down movement is coordinated with the direction, amount, and speed of the tension frame's movement, so that the upper and lower threads are twisted and a double line lock stitch is made on the fabric. When embroidery continues continuously, complete the computerized embroidery of the pattern.
