Abstract

The invention relates to a needle distance adjusting device and an operation method thereof. When the needle distance adjusting device is used for adjusting the needle distance, an adjusting column stretches into an adjusting groove and drives a rotating shaft to rotate to the state that a second signal mark is aligned to a second signal screw as the initial reference of the adjusting needle distance, then, a control device controls the drive shaft to rotate to the corresponding position according to the set needle distance, and therefore the phase position of a connecting disc opposite to thedrive shaft is adjusted, the phase and distance between opposite drive shafts at the eccentric position of an outer cylinder face of a drive sleeve of the connecting disc can be adjusted, the distance which can be moved by a tooth frame driven by rotation of the drive shaft can be adjusted, and the needle distance is adjusted. Accordingly, according to the needle distance adjusting device and theoperation method thereof, the needle distance can be adjusted conveniently, the automatic degree is high, and adjustment is accurate.

Description

technical field [0001] The invention relates to a stitch length adjusting device and its operation method, in particular to a stitch length adjustment device and its operation method for sewing machines. Background technique [0002] With the continuous improvement of the technical level, the automation trend of sewing operations has become the trend of the future technological development of sewing machines. At present, the stitch length adjustment method of wrist bending machines is still manual adjustment. The stitch length adjustment is inconvenient to operate, and the accuracy cannot be guaranteed by manual operation. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a stitch length adjusting device and its working method, which can adjust the stitch length conveniently. [0004] In order to achieve the above object, the present invention provides a needle distance adjusti...
