The complete mechanical system of the computerized pattern machine includes the upper shaft, lower shaft, main shaft, needle bar, thread picking mechanism, cutting mechanism, hooking mechanism, feeding mechanism, and pressure mechanism, among other parts, totaling approximately 600 to 700 components. The entire mechanical system is complex in structure and highly precise, with stringent requirements for assembly quality.

The working principle of the computer jacquard machine is described as follows: The crank and connecting rod mechanism installed on the upper shaft delivers the fabric to the needle, which punctures the fabric from below, threading the weft through. The cutting mechanism, in conjunction with the control system, completes the automatic cutting function. The pressure mechanism ensures the friction force in feeding, while the feeding mechanism moves the fabric. As the needle rises from its lowest point, the weft forms a loop due to resistance. During the ascent, the hooking mechanism engages the loop, separating it into two parts, forming a weave knot with the bottom thread. The picking rod then pulls the weft upwards, slowly reaching a high position before starting a gradual descent. At this point, the weft is loose, and the bottom thread is tight, dragging the weave knot downwards until it intertwines with the fabric, completing the stitch.
