Dicing type rubber cut-off machine

The utility model provides a dicing type rubber cut-off machine. The dicing type rubber cut-off machine comprises a platen, a pressing plate and a cutter exposed out of the platen and sliding leftwards and rightwards in a rail groove in the platen. The dicing type rubber cut-off machine further comprises a lead screw transmission device, a lifting device and a strip-type groove, wherein the lead screw transmission device is fixed to the bottom face of the platen and used for driving the cutter to slide; the lifting device is fixed to the top face of the platen and used for pulling, lifting and pressing the pressing plate downwards; the strip-type groove is formed in the position, aligned with the rail groove, of the bottom face of the pressing plate, and the cutter is inserted in the strip-type groove and can slide along the strip-type groove. According to the dicing type rubber cut-off machine, two hydraulic cylinders are adopted to lift and drop the pressing plate, so that rubber on the platen is stressed more uniformly when pressed and clamped by the pressing plate, and the situation that the cutting quality is influenced due to the fact that the rubber is stressed unevenly and deforms, and other positions of the rubber can not be pressed firmly is avoided; the triangular double-edged cutter plated with a Teflon plating layer can cut the rubber apart rapidly, squeezing of the position, making contact with the cutter, of the rubber is reduced, cutting is smoother, and by means of a left-right cutting movement mode, the complexity of a cutting structure is also lowered; when the rubber is cut, blades are hidden in the groove in the bottom face of the pressing plate and slide leftwards and rightwards, so that the safety of equipment is improved.
