1. What does an embroidery machine do
An embroidery machine is a special-purpose sewing machine that performs fine embroidery on fabrics through computer design. This design can be user created, standard on the machine, or made by a third party and purchased for use on the machine.
The embroidery machine is also known as embroidery machine and computerized embroidery machine. It is the most advanced embroidery machine in contemporary times. It can realize the high speed and high efficiency of traditional manual embroidery, and can also realize manual embroidery. Unattainable requirements of “multi-level, multi-function, unity and perfection”. It is an electromechanical product that embodies a variety of high and new technologies. As computerized embroidery replaces manual embroidery, computerized embroidery machines will also become the main machine in the embroidery industry.
Second, the working principle of computerized embroidery machine
First use embroidery CAD software to make a pattern, after generating the pattern, put the embroidery program and pattern on the disk The pieces are successively put into the computer disk drive. Under the control of the program, the computer changes the pattern coordinate value 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 to increase and decrease the speed of the motor. After processing, output three-phase six-time signature, the power amplifier box of the line motor performs power amplification, and the red X and Y stepper motors drive the stretch frame to complete the feeding movement between X and Y; at the same time, the Z stepper motor is driven to drive the motor. The needle moves up and down so that the embroidery continues continuously.
The Z stepper motor drives the machine head transmission mechanism to rotate through the synchronous toothed belt, etc. The specific mechanism of the machine head enables the lead mechanism and the needle to make and move down the upper thread, and puncture the fabric; the hooking mechanism The rotary hook in the middle rotates to make the upper thread go around the bobbin case with the lower thread hidden; the thread take-up mechanism moves, conveys the upper thread, tightens the stitch, and prepares the upper thread segment for the next stitch. The X and Y stepping motors drive the silk frame and the fabric to move in a plane through the synchronous toothed belt and other mechanisms. 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 direction, amount of movement and movement speed of the stretcher frame, so that the upper thread and the lower thread are twisted and placed on the fabric. Make a double bartack. When the embroidery continues continuously, the computerized embroidery of the pattern is completed.
