[0026] The flattening and punching mechanism 6 comprises a height adjusting frame 61, a rotating rod 62, a rolling cylinder 63, a circular punching blade 64, a flattening plate 65, a rotating arm 66, a flattening connecting frame 67, a flattening roller 68 and a spring 69, the height adjusting frame 61 is fixedly connected to the telescopic end of the telescopic air cylinder 5, the rolling cylinder 63 is rotationally connected between the front and rear inner walls of the height adjusting frame 61 through the rotating rod 62, the circular punching blade 64 is arranged on the outer arc surface right side middle part of the rolling cylinder 63, the flattening plates 65 are uniformly arranged on the lower side of the height adjusting frame 61, the rotating arms 66 are rotationally connected to the ends, away from the center of the workbench 1, of the four flattening plates 65 through rotating shafts respectively, the flattening rollers 68 are fixedly connected to the lower sides of the four rotating arms 66 through the flattening connecting frames 67 respectively, the springs 69 are uniformly arranged on the side, facing the center of the workbench 1, of the four rotating arms 66, the ends of the eight springs 69 are fixedly connected to the outer surfaces of the flattening plates 65 on the same side respectively, the motor 9 is fixedly connected to the front middle part of the height adjusting frame 61, the output shaft of the motor 9 is fixedly connected to the front end of the rotating rod 62, the input end of the motor 9 is electrically connected to the output end of the controller 3, the outer surface of the rolling cylinder 63 is bonded with a rubber antiskid pad, the outer surface of the rolling cylinder 63 is provided with a tooth-shaped slitting cutter 10, and the upper surface of the workbench 1 is provided with a tooth-shaped slitting groove.

[0027] The working principle of the automatic punching machine for surgical hole cover is as follows:

[0028] When the automatic punching machine needs to be used, the unwinding roller and the winding roller of the surgical hole cover are placed on the left side and the right side of the automatic punching machine in sequence, then the surgical hole cover is manually guided and placed on the hole cover conveying frame 2, at this time, the upper arc surface of the hole cover conveying frame 2 contacts the lower surface of the surgical hole cover and conveys the surgical hole cover, at this time, the upper surface of the workbench 1 also contacts the lower surface of the surgical hole cover, then the unwinding roller and the winding roller can be adjusted and controlled to perform material conveying operation.

[0029] When the unwinding and take-up rollers have been feeding material for a period of time and reach the opening of the surgical drape, the controller 3 can be adjusted to start the motor 9. The output shaft of the motor 9 rotates, which in turn drives the rolling cylinder 63 to rotate at a constant speed. When the circular punching blade 64 rotates to its uppermost position, the external air compressor pump can be adjusted to start the telescopic cylinder 5. The telescopic end of the telescopic cylinder 5 extends, which in turn moves the height adjustment frame 61 downward until the outer surface of the rolling cylinder 63 contacts the upper surface of the surgical drape. It is worth noting that the rotational speed of the rolling cylinder 63 is related to the speed of the unwinding and take-up rollers. With a consistent conveying speed, as the height adjustment frame 61 moves downward, the outer surface of the flattening roller 68 first contacts the upper surface of the surgical drape. As the height adjustment frame 61 continues to move downward, the rotating arm 66 will change angle around the central axis of the rotating shaft, thereby causing the flattening roller 68 to flatten the surgical drape around the discharge port 7, so that the opening of the surgical drape on the upper side of the discharge port 7 is in a relatively flat arc surface. At the same time, it will also be affected by the restoring force of the spring 69, so that the flattening roller 68 has a good flattening effect when flattening the surgical drape.

[0030] As the grinding cylinder 63 rotates continuously, when the circular punching blade 64 on the grinding cylinder 63 reaches its lowest position, it will simultaneously extend from right to left into the interior of the slag outlet 7, cutting a hole on the upper side of the slag outlet 7. This hole is the surgical hole for the surgical drape. Then, the cut circular waste material will fall out of the punching machine due to gravity. At this time, the external air compressor pump can be adjusted, the telescopic cylinder 5 will operate, and the telescopic end of the telescopic cylinder 5 will retract, thereby resetting the height adjustment frame 61 and continuing the continuous automatic punching operation of the surgical drape.

[0031] It is worth noting that the core chip of the controller 3 disclosed in the above embodiments is a PLC microcontroller, specifically the STM32. The telescopic cylinder 5 and the motor 9 can be freely configured according to the actual application scenario. It is recommended to use the KCP95 telescopic cylinder for the telescopic cylinder 5 and the 5IK90RA speed-regulating motor for the motor 9. The controller 3 controls the operation of the motor 9 using methods commonly used in the prior art.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
