The entire mechanical system of the computer 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 to 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 upper shaft delivers the fabric to the needle, which pierces through the fabric to pass the thread through. The cutting mechanism, in coordination 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 its lowest point, the thread forms a loop due to resistance. During the rise, the hooking mechanism engages the loop, separating it and creating a weave knot with the底线. The picking rod pulls out the thread, slowly rising to a higher position, then begins to descend slowly. At this point, the thread is loose, and the底线 is taut, pulling the weave knot downward until it intertwines with the fabric, completing the stitching pattern.
