The entire mechanical system of the computerized embroidery 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 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, 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 bottom point, the weft forms a loop due to resistance. During the upward movement, the hooking mechanism catches the loop, separating it to form a 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 knot down until it weaves into the fabric, completing the stitching.
