　　 3. The mechanical and electrical principles of embroidery machines
An embroidery machine is also called an embroidery machine or a computerized embroidery machine. The working principle of the embroidery machine: first use the embroidery mechanism version software to make a sample. After the sample is generated (embroidery machine printing), the discs containing the embroidery program and the pattern are put into one after another. In the computer disk drive, under the control of the program, the computer converts the coordinate value of the pattern into an electrical signal equivalent to the displacement in the x and y directions of the stretcher, and sends it to the x, y, and z single-chip microcomputer system for motor speed up and down processing, and then outputs three Phase six-beat signal, the power amplifier box of the motor performs power amplification, the red x, y stepping motor drives the stretch frame to complete the feed movement between x and y; at the same time, the z stepping motor is driven to move the needle up and down, thereby Make embroidery go on continuously.
z The stepping motor drives the transmission mechanism of the machine head to rotate through the 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 hook thread 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. The 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. 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.
