[0057] Working principle of the automatic suture machine for the anastomotic orifice reinforcing and repairing assembly:

[0058] When the automatic suture machine for the anastomotic orifice reinforcing and repairing assembly is working, the backing feeding device is started by touching the display screen, the power switch and the control switch. When the backing feeding device is working, the backing is fed by the feeding roller transmission motor under the control of the PLC programmable controller. After a certain length of the backing is fed, the backing is cut off by the backing cutting cylinder and the cutting knife. Then, the cutting-off backing is pressed by the pressing cylinder and the pressing plate through the synchronous belt transmission motor and the synchronous belt. The cutting-off backing is transferred to the folding corner station along the workbench and is folded at the upper part of the backing.

[0059] When the backing folding corner device is working, the reinforcing and repairing patch is placed at the upper part of the backing. Then, the front and rear positions of the reinforcing and repairing patch are corrected by the reinforcing and repairing patch front and rear moving correction cylinder and the correction plate under the control of the PLC programmable controller. The reinforcing and repairing patch is pressed tightly on the upper part of the backing by the pressing plate of the reinforcing and repairing patch up and down pressing cylinder. The front and rear displacement of the backing folding corner is adjusted by the backing folding corner front and rear moving cylinder. The backing is pressed tightly by the backing folding corner up and down cylinder. The backing is folded at the front end by the folding plate set on the backing folding corner left and right moving cylinder. The backing is folded into the folding corner with the designed length. After the folding corner is completed, the backing folding corner front and rear moving cylinder is withdrawn.

[0060] After the completion of the backer hemming, the reinforcement patch assembly conveying device is assembled under the control of the PLC programmable controller, and the X-direction and Y-direction linear motor modules are driven to move the reinforcement patch assembly that has been hemmed to the lower part of the corner cutting mechanism along the workbench. The moving cutter one of the corner cutting mechanism first cuts off the corner on one side, and then moves to the other moving cutter two to cut off the corner on the other side. After the corner cutting is completed, the reinforcement patch assembly conveying device conveys the corner-cut reinforcement patch assembly to the lower part of the industrial sewing machine of the reinforcement patch sewing device one for one-side sewing. After the one-side sewing of the reinforcement patch assembly, the reinforcement patch assembly conveying device is conveyed forward to exit the needle tip position. The front and rear telescopic air cylinder is extended, the thread pressing air cylinder one is started, the pressing plate presses the last loop after sewing, the thread pulling air cylinder of the reinforcement patch sewing device one works, and the thread is pulled out a distance to leave a thread end one.
