The entire mechanical system of the computer jacquard machine includes the upper and lower shafts, main shaft, needle bar, thread picking mechanism, cutting mechanism, hooking mechanism, feeding mechanism, and material pressing mechanism, with approximately 600-700 parts. The entire mechanical system is complex in structure and highly precise, demanding a high standard of assembly quality.

The working principle of the computerized pattern loom is described as follows: The crank and connecting rod mechanism installed on the upper shaft delivers fabric to the needle, which pierces the fabric downward, 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 of the feeding process, while the feeding mechanism moves the fabric. As the needle rises from the low point, the weft forms a loop due to obstruction. During the ascent, the hooking mechanism engages the loop, separating it front to back, creating a woven knot with the底线. The picking rod pulls out the weft, slowly ascending to a high position before beginning a gradual descent. At this point, the weft is loose, and the底线 is taut, dragging the woven knot downward until it intertwines within the fabric, completing the stitching.
