Operating principle and pattern function of computerized quilting machine

Computerized quilting machines and traditional quilting machines operate on the same principle, both using an X-Y-Z motion system. The Z-axis movement is controlled synchronously by a stepper motor in the machine head and base. The X-axis movement is controlled by the left-right movement of the machine head, and the Y-axis movement is controlled by the forward-backward movement of the machine head. A single-needle computerized quilting machine is a type of computerized quilting machine that has only one machine head, hence the name. It has a wide range of applications, suitable for quilting various quilts, sleeping bags, bedspreads, and curtains. It features good machine stability, low price, adjustable pattern size, simple operation, good quilting thickness, uniform stitch count, and quiet operation.

Computerized quilting machines also have a pattern function, allowing patterns to be expanded or reduced horizontally and vertically by 50%-200%, with automatic repair in 1% increments. During operation, if a stitch is broken or there is no bobbin thread, causing missed repairs, the machine can automatically or manually use a designated needle to return along the stitch direction to make the repair. After activating the reinforced quilting function, the quilting machine automatically performs back-and-forth stitches at specific points. This ensures high reliability, even stitching, and minimal pattern deformation.

Taking bedding as an example, bedding generally consists of two parts: the filling material and the outer fabric. The filling material can be either wadding or loose fiber. Loose fiber bedding fillings have an irregular structure and shape, are prone to shifting and shrinking, and have uneven thickness. To ensure a tight fit between the outer fabric and the inner filling, and to achieve uniform thickness, the outer fabric and inner filling are sewn together (including stitching) in parallel straight lines or decorative patterns. This process, which enhances both aesthetics and practicality, is called quilting.

Computerized quilting machines combine quilting machines with a computer operating system. China mastered this technology in the mid-1990s, filling the technological gap in electronic control systems for the Chinese quilting industry. Its development solved problems that ordinary quilting machines could not overcome.
