The entire mechanical system of the computer pattern machine includes the upper shaft, lower shaft, 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, 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 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 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 engages the loop, separating it front and back, creating a woven knot with the底线. The picking rod pulls out the weft, slowly ascending to a high position before beginning a slow descent. At this point, the weft is loose, and the底线 is taut, dragging the woven knot downward until it intertwines within the fabric, completing the stitching.
