As the improvement of above-mentioned technical proposal, the servo drive includes servomotor, screw mandrel and feed screw nut, institute
Servomotor is stated on a bottom plate, the output end of the servomotor is connected with screw mandrel, and the feed screw nut is set in silk
On bar, the X-axis guide rail parallel with screw mandrel is installed with the bottom plate, slide is slidably fitted with the X-axis guide rail, it is described
Slide is fixedly connected with feed screw nut, and the delivery sheet and middle presser feet are arranged on slide.
As the improvement of above-mentioned technical proposal, press cylinder is installed on the slide, pressed in the press cylinder driving
Pin lifts.
As the improvement of above-mentioned technical proposal, Y-axis guide rail and telescopic cylinder are installed with the slide, it is described flexible
Cylinder can drive a connecting seat to be slided along Y-axis guide rail, and described delivery sheet one end is arranged on connecting seat.
As the improvement of above-mentioned technical proposal, the delivery sheet lower surface reclines on the table and can hold up work along Y-axis
Make the material on platform.
The beneficial effects of the utility model have：
This compensation mechanism is combined using servo drive with fibre optical sensor, realizes self-feeding, works as material
During by fibre optical sensor, material width is calculated by the time blocked automatically and carries out mathematic interpolation with established standardses width,
And be fed back to control assembly, servo drive compensates regulation during suture, pin number, needle gage during adjustment sewing or
Needle path, efficiently solve because of the otherness of single material and caused by sew needle path deviation, improve the aesthetic property of product.
