[0053] When the position of the foam box is punched, the longitudinal moving part 302 drives the transverse rod 305 to move longitudinally, and the transverse moving part 303 drives the longitudinal rod 304 to move transversely. The longitudinal rod 304 and the transverse rod 305 work together to drive the rectangular block 306 to move to the required position to determine the position of the foam box.

[0054] Then, the lead screw slider group 202 works again, driving the support plate I 203 to move upward, and the support plate I 203 drives the foam box to move to the punched surface of the foam box and insert it into the cutting wire 406, but does not contact the rod at the lower end of the ring 404; then, the cutting wire 406 is heated, and at the same time, the motor III 417 is started, driving the disc II 416 to rotate, at this time, the gear teeth on the side of the disc II 416 mesh with the gear teeth at the lower end of the ring frame 418, and drive the ring frame 418 to move to the left, and the ring frame 418 drives the lower rack 420 to move to the left, and the lower rack 420 drives the gear I 414 to rotate 90°, and the gear I 414 drives the round rod III 413 to rotate 90°, and the cam on the round rod III 413 drives the U-shaped frame 412 to move downward, and the U-shaped frame 412 drives the ring 404 downward Move, so that the rod at the lower end of the ring 404 is inserted into the foam box. At the same time, the ring frame 418 drives the upper rack 419 to move left, and the upper rack 419 drives the outer gear of the ratchet 411 to rotate clockwise, and the outer gear of the ratchet 411 drives the inner shaft of the ratchet 411 to rotate clockwise, and the inner shaft of the ratchet 411 drives the round rod II 410 to rotate, and the round rod II 410 drives the round rod I 403 to rotate, and the round rod I 403 drives the auxiliary plate 402 and the ring 404 to rotate, and the lower rack 420 drives the cutting wire 406 to rotate, and the cutting wire 406 punches the foam box. After the punching is completed, the lead screw slider group 202 works to drive the support plate I 203 to move downward, and the support plate I 203 drives the foam box to move downward, and the foam box is placed on the conveyor belt 101 and moved out of the equipment;

[0055] At this time, the rod at the lower end of the ring 404 is inserted with the circular waste remaining after the foam box is punched. Then, the longitudinal moving part 302 drives the transverse rod 305 to move longitudinally, and the transverse moving part 303 drives the longitudinal rod 304 to move transversely. The longitudinal rod 304 and the transverse rod 305 work together to drive the rectangular block 306 to move to the clamping plate 307, so that the clamping plate 307 is clamped on the upper end of the waste. Then, the motor III 417 is started again to drive the disc II 416 to rotate. At this time, the disc II 416 rotates until the gear teeth on its side mesh with the gear teeth on the upper end of the ring frame 418. Then, the disc II 416 drives the ring frame 418 to move to the right, and the ring frame 418 drives the upper rack 419 to move to the right. The upper rack 419 only drives the outer gear of the ratchet 411 to rotate counterclockwise, and the inner gear of the ratchet 411 does not rotate. At the same time, the ring frame 418 drives the lower rack 420 to move rightward. When the gear teeth on the lower rack 420 mesh with the gear I 414, the gear I 414 rotates 90°, and the gear I 414 drives the round rod III 413 to rotate 90°. The round rod III 413 drives the U-shaped frame 412 to move upward, and the U-shaped frame 412 drives the gear I 414 to move upward. The rod at the lower end of the gear I 414 moves upward. At this time, the waste on the rod at the lower end of the gear I 414 will be caught by the clamping plate 307 and fall into the collection box 308, and is collected by the collection box 308.

[0056] When it is necessary to punch holes on different sides of the foam box, the foam box needs to be rotated. At this time, motor I 206 is started, driving the cross bar 205 to rotate, and the cross bar 205 drives the two synchronous wheels 208 to rotate. The two synchronous wheels 208 respectively drive the two clamping rods 209 to rotate, and the two clamping rods 209 simultaneously drive the foam box clamped therein to rotate, so as to facilitate punching holes on different sides of the foam box.
