The Y of described mop dish goes up to the midline to the Y that impeller-hub and described screw pair are arranged in the mop dish.
Described Connection Block comprises that a T shape seat is fixedlyed connected with T shape seat with one and synchronous cog belt is fixed on profile of tooth pressing plate on the T shape seat, the guidance supporting rack fixed installation of described T shape seat and mop dish.
The beneficial effect that the utility model produces is: send the step accurately, stress balance, stitching evenly, the mop dish motion of sewing round end buttonhole sewing Sewing machines attractive in appearance.
1, because the utility model has adopted Synchronous Belt Drives mechanism to drive mop dish X to motion, to compare to motion to promote mop dish X with cam with the X that prior art adopts, noise is little, and X goes on foot accurately low cost of manufacture to sending.
2, because being nut, the screw pair kind of drive of the present utility model under synchronous cog belt drives, drives leading screw, leading screw promotion mop dish Y to motion, adopt Synchronous Belt Drives can conveniently select Y to the installation position of drive motors on the Sewing machines support, go up to the midline to adapt to the Y that screw pair is configured in the mop dish, guarantee mop dish stress balance, motion steadily.
3, the utility model sewing thread trace is even, attractive in appearance.
The utility model is described in further detail below in conjunction with drawings and Examples.
