[0032] When the automatic stitching machine for the anastomotic orifice reinforcing and repairing assembly is working, the backing feeding device is started through the touch operation of the display screen, the power switch and the control switch. When the backing feeding device is working, the backing is fed by the feeding main roller driven by the feeding roller transmission motor under the control of the PLC programmable controller. After the backing is cut by the cutting knife driven by the backing cutting cylinder when the length of the backing reaches a certain length, the backing is pressed by the pressing plate driven by the pressing cylinder through the synchronous belt transmission motor and the synchronous belt, and the pressed backing is transferred along the workbench to the workbench folding edge station.

[0033] When the backing folding edge device is working, the reinforcing and repairing patch is placed on the upper part of the backing. Under the control of the PLC programmable controller, 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 correction plate, and the reinforcing and repairing patch is pressed on the upper part of the backing by the pressing plate of the up and down pressing cylinder. The backing folding edge front and rear moving cylinder is started, the displacement of the backing folding edge is adjusted, the backing is pressed by the backing folding edge up and down cylinder, the backing is folded by the folding plate set on the backing folding edge left and right moving cylinder, and the front end of the backing is pushed backward to fold the edge.

The moving cutter one of the corner cutting mechanism first cuts off the corner on one side, and then moves to the other side 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 cylinders are 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. The industrial sewing machine is reversed to make the sewing machine bend needle thread breaking. Under the control of the PLC, the X and Y linear transmission modules of the reinforcement patch assembly conveying device convey the reinforcement patch assembly after being pressed to the transfer position of the vacuum suction plate two. The rear end thread pulling air cylinder is extended again, the rear end thread pulling lifting air cylinder is pressed down, the thread is hooked through the thread hooking plate, the rear end thread pulling air cylinder is retracted, a required length of thread is reserved at the rear end, the thread pulling air cylinder is pulled again, the front end thread pulling air cylinder is extended, the thread is hooked and retracted, the pneumatic finger clamps the thread when retracted, the pneumatic scissors lifting air cylinder is down to cut the thread end through the pneumatic scissors. The reinforcement patch assembly conveying device returns to the original position to perform the next cycle.

[0035] The reinforcement patch assembly discharging device is started, the pressing plate is moved to the transfer position of the vacuum suction plate two of the workbench, the upper and lower pressing air cylinders of the reinforcement patch press the reinforcement patch assembly after one-side sewing to the lower part of the industrial sewing machine of the reinforcement patch sewing device two for the other-side sewing of the reinforcement patch assembly. After the other-side sewing of the reinforcement patch assembly, the reinforcement patch discharging device is conveyed forward to exit the needle tip position. The front and rear telescopic air cylinders are extended, the thread pressing air cylinder two is started, the pressing plate one presses the last loop after sewing, the thread pulling air cylinder of the reinforcement patch sewing device two works, the thread is pulled out a distance to leave a thread end two. The industrial sewing machine is reversed to make the sewing machine bend needle thread breaking. Under the control of the PLC, the rear end thread pulling air cylinder is extended again, the rear end thread pulling lifting air cylinder is pressed down, the thread is hooked through the thread hooking plate, the rear end thread pulling air cylinder is retracted, a required length of thread is reserved at the rear end, the thread pulling air cylinder is pulled again, the front end thread pulling air cylinder is extended, the thread is hooked and retracted, the pneumatic finger clamps the thread when retracted, the pneumatic scissors lifting air cylinder is down to cut the thread end through the pneumatic scissors. After the thread is cut by the pneumatic scissors, the reinforcement patch assembly is formed. The reinforcement patch assembly is sewn from the reinforcement patch and the backer. The linear motor module of the reinforcement patch assembly discharging device of the reinforcement patch assembly discharging device drives the reinforcement patch assembly to discharge and convey to the discharging slide, and the reinforcement patch assembly product is discharged.

5. The assembly stitching and unloading device of the automatic stitching machine for reinforced and repaired components according to claim 4, characterized in that, In the aforementioned reinforcement and repair assembly feeding device (9), the linear motor module (9-2) of the reinforcement and repair assembly feeding device is mounted on the front frame (1) of the reinforcement and repair piece assembly stitching device two (8) via the reinforcement and repair assembly feeding device mounting bracket (9-1). The reinforcement and repair piece upper and lower pressing cylinder (9-5) is mounted on one side of the pressing cylinder mounting bracket (9-4). The pressing cylinder mounting bracket (9-4) is mounted on the slider one (9-3) of the linear motor module (9-2) of the reinforcement and repair assembly feeding device, and can move back and forth under the transmission of the linear motor module (9-2) of the reinforcement and repair assembly feeding device.

6. The assembly stitching and unloading device of the automatic stitching machine for reinforced repair assemblies according to claim 4, characterized in that, In the aforementioned reinforcement and repair assembly discharge device (9), the lower part of the reinforcement and repair piece pressing cylinder (9-5) is equipped with a pressure cylinder second mounting plate (9-10), the pressure cylinder second (9-7) is mounted on the pressure cylinder second mounting plate (9-10), the front and rear telescopic cylinder (9-6) is mounted on the pressure cylinder second (9-7) push plate, and the front and rear telescopic cylinder (9-6) push rod is equipped with a pressure plate second (9-8).
