The entire mechanical system of the computerized pattern machine includes the top and bottom shafts, main shaft, needle bar, thread picking mechanism, cutting mechanism, hooking mechanism, feeding mechanism, and material pressing mechanism, comprising approximately 600 to 700 parts. The entire mechanical system is complex in structure and highly precise, with stringent requirements for 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, 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, 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 upward movement, the hooking mechanism catches the loop, separating it front and back, creating a cross-line knot with the底线. The pick-up rod pulls out the weft, slowly rising to a high position and then beginning a slow descent. At this point, the weft is loose, and the底线 is taut, dragging the cross-line knot downward until it weaves into the fabric, completing the stitching.
