Since the length of the edge of the sole is shorter than that of the edge of the upper, the upper needs to be bulged after sewing, and the edge of the sole and the edge of the upper need to be aligned. Therefore, the feed gear 712 that fits with the upper and drives the upper to move has a relatively high rotation speed, and the feed spur gear 613 that fits with the sole and drives the sole to move has a relatively low rotation speed, so that the edge of the sole and the edge of the upper can be aligned after sewing. However, in the current technology, even if the edge of the sole and the edge of the upper are aligned after sewing, the sewing stitch length will be different, because the shape of the edge of the sole is relatively irregular. In this application, the control module of the single-chip microcomputer controls the lower feed motor 712 to adjust the feed speed. 27 is used to control the rotation speed of the feed tooth 712, and the rotation speed of the loading spur gear 613 is controlled by controlling the upper feed motor 617, thereby controlling the rotation speed ratio of the feed tooth 712 and the loading spur gear 613. When the user sews for the first time, when sewing different positions of the edge of the sole, the different rotation speed ratios of the feed tooth 712 and the loading spur gear 613 are adjusted to make the sewing stitch lengths equal, and the adjustment data will be saved in the data storage module. When sewing next time, according to the adjustment data stored in the data storage module, the control module will automatically adjust the appropriate rotation speed ratio of the feed tooth 712 and the loading spur gear 613 at the appropriate time, so that the edge of the sole and the edge of the shoe upper are aligned after sewing and the stitch lengths are equal.
