The entire mechanical system of the computerized pattern machine includes the upper and lower shafts, main shaft, needle bar, threading 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 high quality assembly.

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 warp yarn through. The cutting mechanism, in coordination 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 low point, the warp yarn forms a loop due to obstruction. During the ascent, the hooking mechanism engages the loop, separating it front to back, creating a knot with the weft. The pick-up rod pulls out the warp yarn, slowly ascending to a high position and then beginning a slow descent. At this point, the warp yarn is loose, and the weft is taut, dragging the knot downward until it intertwines within the fabric, completing the stitch pattern.
