Embroidery machine, literally I think everyone should understand, embroidery machine, embroidery machine, or embroidery machine. When embroidery first broke away from manual embroidery, the so-called embroidery machine at that time was actually not an embroidery machine in the true sense, because the embroidery machine at that time was a traditional sewing machine, replaced with a bottom plate with a small round hole, and the sewing machine needle kept on. Going in and out, coupled with holding the stretched cloth with the embroidery frame, moving back and forth, in fact, this so-called embroidery machine is still a kind of hand embroidery.
First use embroidery CAD software to make a pattern. After generating the pattern, put the disks containing the embroidery program and the pattern into the computer disk drive respectively. Under the control of the program, the computer will change the pattern coordinate value to the X, Y direction of the stretch frame. The electric signal with the equivalent displacement is sent to the X, Y, Z single-chip microcomputer system for motor speed up and down processing, and then outputs the three-phase six-time signature. The power amplifier box of the line motor performs power amplification, and the red X, Y stepping motor drives it. The stretch frame completes the feed movement between X and Y; at the same time, it drives the Z stepping motor to drive the needle to move up and down, so that the embroidery can go on continuously.
The Z stepping motor drives the transmission mechanism of the machine head to rotate through a synchronous toothed belt, etc. The specific mechanism of the machine head makes the lead mechanism and the needle take the lead to make and move the upper thread and pierce the fabric; the hook in the thread hook mechanism rotates to make The upper thread bypasses the bobbin case with the lower thread; the thread take-up mechanism moves, conveys the upper thread, tightens the stitches, and prepares the upper thread segment of the next stitch. X, 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. The speed of the up and down movement of the machine needle is coordinated with the moving direction, amount of movement and moving speed of the stretch frame, so that the upper thread and the bottom thread are twisted on the fabric. Make a double-thread lock stitch. When the embroidery continues continuously, computer embroidery of the pattern is completed.
