The entire mechanical system of the computer pattern machine includes the upper and lower shafts, main shaft, needle bar, pick-up mechanism, cutting mechanism, hooking mechanism, feeding mechanism, and pressure mechanism, among other components, totaling approximately 600-700 parts. The entire mechanical system is complex in structure and highly precise, with stringent requirements for assembly quality.

The working principle of the computerized embroidery machine 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 its lowest point, the weft forms a loop due to resistance. During the ascent, the hooking mechanism engages the loop, separating it into two parts, creating a knot with the bottom thread. The pick-up rod pulls the weft upwards, slowly reaching a higher position before beginning a gradual descent. At this point, the weft is loose, and the bottom thread is taut, dragging the knot downwards until it weaves into the fabric, completing the stitching.
