The stitch length is a distance between a needle and a needle, and a distance between a needle hole and a cut becomes a margin when sewing the clothes. In front fly sewing, a transmission mechanism is arranged in front of a machine needle shaft, the speed of belt transmission is matched with the rotating speed of a sewing machine, and the cloth can smoothly pass through the equipment, otherwise, the conditions of stacking, dragging and inconsistent needle pitch can occur.
Since the actual stitch length deviates from the theory in the front fly seam and is related to the rotational speed of the sewing machine, a mathematical model of the actual stitch length needs to be established.

Specifically, the trial teaching process is respectively matched at three speeds to obtain the rotating speeds V of the sewing machine1，V2、V3Time-matched cloth transmission speed VC1，VC2、VC3。
An equation is established to obtain three sets of parameters:
VC1＝DV1(aV1 2+bV1+c)；
VC2＝DV2(aV2 2+bV2+c)；
VC3＝DV3(aV3 2+bV3+c)。
the teaching process comprises the following steps: setting a predetermined stitch length D, a rotational speed V of the sewing machine1Manual adjustment, cloth transmission speed V in stable sewingC1The cut pieces are sewn for many times at the speed, so that the sewn cut pieces can meet the technological requirements, and the input of the set of parameters can be confirmed.

The third group of parameters are operated in the same way to confirm the rotating speed V of the third group of data sewing machine3Speed of cloth transport VC3。
And S103, obtaining a matching curve through a fitting algorithm according to the trial teaching parameters.

solving according to the equation to obtain values of a, b and c;
and obtaining a fitting model according to the values of a, b and c obtained by the solution: vC＝DV0(aV0 2+bV0+c)；
