The lifting cylinder 21 is started again to reset the lifting platform 23, and then the positioning motor 34 is started. The positioning motor 34 drives the positioning bidirectional screw 33 to rotate, thereby driving the two positioning plates 35 to move toward each other, thereby clamping the rubber sheet, and then the conveying cylinder 32 is started again. The conveying cylinder 32 pushes the rubber sheet to the next process, and pushes the unprocessed rubber sheet to the bottom of the cutting component 4 again. Through a lifting process, the two rubber sheets that are bonded to each other are separated, so as to avoid the rubber sheets sticking together after cutting and affecting the subsequent processing quality and production efficiency, which is conducive to improving work efficiency.
