The second hydraulic cylinder 76 can push the tool holder 74 to move downward under the limitation of the slide groove 73 and the slider 72 until the cutting knife 75 cuts the EPE sheet. After the cutting knife 75 is lifted, the third hydraulic cylinder 84 controls the cross plate 86 to drive the limit plate 87 to move downward, and continues to push the EPE sheet so that the uncut EPE sheet pushes the cut EPE sheet to fall into the collection box 811 for collection, so as to complete the automatic material return, thereby reducing labor and improving production efficiency.
