The complete mechanical system of the computerized pattern machine includes the top and bottom shafts, main shaft, needle bar, picking mechanism, cutting mechanism, hooking mechanism, feeding mechanism, and material pressing mechanism, with approximately 600-700 components. The entire mechanical system is complex in structure and highly precise, demanding a high level 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 transmits the fabric to the needle. The needle pierces through the fabric from below, threading the weft. The cutting mechanism, in conjunction with the control system, completes the automatic cutting function. The pressure mechanism ensures the friction force of the feeding, while the feeding mechanism moves the fabric. As the needle rises from the bottom, the weft forms a loop due to obstruction. During the ascent, the hooking mechanism catches the loop, separating it to form a weave knot with the底线. The picking rod pulls out the weft, slowly rising to a higher position before beginning a gradual descent. At this point, the weft is loose and the底线 is tight, dragging the weave knot downward until it intertwines with the fabric, completing the stitching.
