Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machine equipment, in particular to a quick installation and maintenance structure for an embroidery machine drive shaft. Background Art

[0002] Embroidery machine mechanical and electrical principles:

[0003] First, use the embroidery CAD software to make a plate. After the sample is generated, the disk containing the embroidery program and pattern is placed in the computer disk drive one by one. Under the control of the program, the computer converts the pattern coordinate value into an electrical signal equivalent to the displacement of the stretch frame in the X and Y directions, and sends it to the X, Y, and Z single-chip computer system for motor speed increase and decrease processing, and then outputs a three-phase six-beat number. The power amplifier box of the thread motor performs power amplification, and the red support 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 drives the machine needle to move up and down, so that the embroidery can proceed continuously. The Z stepper motor drives the head transmission mechanism to rotate through the synchronous toothed belt, etc. The specific mechanism of the head makes the lead mechanism and the machine needle lead the upper thread to move up and down and pierce the fabric; the rotary shuttle in the hook mechanism rotates, so that the upper thread bypasses the bobbin case with the bottom thread; the thread picking mechanism moves, conveys the upper thread, tightens the stitches, and prepares the upper thread segment of the next stitch. The X and Y stepper motors drive the silk frame and the fabric to move in a plane through the synchronous toothed belt and other mechanisms. Each stitch point on the fabric to be embroidered is sent to the machine needle for embroidery. The speed of the needle's up and down movement is coordinated with the direction, amount and speed of the stretcher frame, so that the upper thread and the lower thread are twisted together to make a double-thread lock stitch on the fabric. When the embroidery continues, the computer embroidery of the pattern is completed.
