Today, I will introduce to you the mechanical and electrical principles of embroidery machines. The red X and Y stepping motors drive the stretch frame to complete the feed movement between X and Y; at the same time, the Z stepping motor is driven Wholesale Rhinestone Hot Mixed Embroidery Machine Manufacturers to drive the needle to move up and down, so that the embroidery can go on continuously. Make a double-thread lock stitch.

After generating the pattern, put the disk containing the embroidery program and pattern into the computer disk drive respectively. The specific mechanism of the machine head makes the lead mechanism and the needle take the lead to make and move the upper thread, pierce the fabric; the hook in the thread hook mechanism rotates to make The upper thread goes around the bobbin case with the lower thread; the thread take-up mechanism moves, conveys the upper thread, tightens the stitch, and prepares the upper thread segment of the next stitch. The speed of the up and down movement of the machine needle is coordinated with the movement direction, amount and speed of the stretch frame, so that the upper thread and the bottom thread are twisted on the fabric.

The Z stepping motor drives the transmission mechanism of the machine head to rotate through the synchronous toothed belt, etc. X and Y stepping motors drive the silk frame and fabric to move in a plane through mechanisms such as synchronous toothed belts.. Each stitch point to be embroidered on the fabric is sent to the machine needle for embroidery. First use embroidery CAD software such as the commonly used Tajima or Fuyi embroidery software to make a pattern.

Under the control of the program, the computer will set the pattern coordinates The value is changed to an electrical signal equivalent to the displacement in the X and Y directions of the stretcher, and sent to the X, Y, Z single-chip microcomputer system for motor speed up and down processing, three-phase six-time signatures are output, and the power amplifier box of the line motor performs power amplification. When the embroidery continues continuously, computer embroidery of the pattern is completed
