At this time, the second cylinder 336 is started, and the second cylinder 336 drives the clamping plate 337 to move. The clamping plate 337 clamps and fixes the bottom plate at the top of the connecting plate 34. When the push plate 332 is pressed against the punch When the bottom plate is squeezed after completion, the clamping plate 337 can drive the bottom plate that has not been punched to move. When the bottom plate after punching is completely discharged, the bottom plate that has not been punched is at the top of the support plate 323, and the pressing rod 334 on the other side squeezes the pressing switch 47 on the other side, so that the storage box 41 on the other side starts to load materials. Therefore, repeated operations can achieve continuous stamping and improve work efficiency. After the bottom plate is at the top of the support plate 323, the first cylinder 22 is started, and the first cylinder 22 pushes the punching body 23 to move downward, and the punching body 23 pushes the bottom plate to move downward. The movement of the bottom plate drives the support plate 323 to slide downward, so that the support plate 323 enters the overlap groove 311, and the support plate 323 is at the same level as the bottom end of the punching box 31.

Then the electric slider 331 is started, and the electric slider 331 drives the push plate 332 to move, and the push plate 332 drives the first unloading plate 333 to move. The push plate 332 squeezes the bottom plate, and the first unloading plate 333 moves out of the placement groove 314 to push the garbage inside the punching box 31 and the overlap groove 311. After the bottom plate is squeezed, it squeezes the limiting scraper plate 316. After being squeezed, the limiting scraper plate 316 deflects to a horizontal state, and when the bottom plate passes through the top of the limiting scraper plate 316, the limiting scraper The plate 316 scrapes the debris at the bottom of the bottom plate so that the debris is cleaned and collected in the punching box 31, and the debris scraped by the first discharge plate 333 is discharged through the discharge trough 312 into the first collecting trough 11 for collection, thereby avoiding the debris from polluting the environment. When the bottom plate passes through the top of the limiting scraper plate 316, the cleaning bevel block 342 is squeezed. Since the cleaning bevel block 342 is provided with an inclined surface, the cleaning bevel block 342 gradually rises after being squeezed to squeeze the third spring 341. When the bottom plate passes through the cleaning bevel block 342, the cleaning brush 343 can sweep the debris at the top cleaning end of the bottom plate to avoid the debris remaining at the top of the bottom plate from being scattered to other places.
