Embodiment Construction
[0020] Describe the present invention below in conjunction with specific embodiment:
[0021] The method for controlling the electronic pattern machine in this embodiment to adapt to sewing materials of different thicknesses adopts the following steps:
[0022] Step 1: Establish the displacement formula of the needle bar of the electronic pattern machine:
[0023] The task of the needle bar mechanism is to guide the upper thread through the sewing material and form a thread loop in preparation for the interlocking of the sutures. The main shaft and the needle bar are connected together by a double-crank thread take-up crank and a connecting rod. The main parameters of this mechanism are the crank radius R and the connecting rod length L, and λ=R / L. In the needle bar mechanism, the longer the length of the connecting rod, the smaller the λ value, and the closer the motion of the needle bar is to simple harmonic motion, the acceleration changes most smoothly, and the inertia ge...
