Quilting and embroidering are common technical means for textile and garment companies. However, as consumers demand improvements in technology and design, many companies, especially export companies, hope to find a computerized embroidery machine that can be quilted and can be embroidered at the same time. . Compared with the traditional quilting machine, the embroidery machine not only has the existing functions of the quilting machine and the embroidery machine, but also has a clear stitch line, a high embroidery precision, a significant increase in eating thickness, a fast operation speed, and a high output. Not easy to jumper and other features. The embroidery machine can perfectly process all kinds of complicated patterns compiled on the entire coordinate system under the precise computer system control. By driving the servo motors on the X-axis and Y-axis, the frame-moving function is realized. The servo system control principle is as follows: The key technology of the computer quilting control system is the linkage control technology of the saddle rack and the roller and the needle row. The saddle control, the roller control and the spindle control must be synchronously controlled. The saddle frame or the roller acceleration and the feeding time must be accurately calculated. The saddle should be optimized. The frame or roller drives the command control curve to inform the overall performance indicators of the saddle rack and the roller system, and realize the automation of the quilting production process. In the mechanical design, the corresponding electronic gear ratio is determined by the pulse equivalent of the upper computer system and different mechanical structures, belt pulley deceleration or ball screw direct connection. The control of the servo part is as shown in the figure:
