The complete 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 embroidery machine is described as follows: The crank and connecting rod mechanism installed on the main shaft transfers 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 for 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 upward movement, the hooking mechanism catches the loop, separating it front and back, creating a weft knot with the底线. The pick-up rod pulls the weft upwards, slowly reaching a higher position and then begins to descend slowly. At this point, the weft is loose, and the底线 is taut, dragging the weft knot downwards until it intertwines with the fabric, completing the stitching.
