The utility model relates to a material divider for uniform feeding of a butting machine. The material divider comprises baffles and two diversion baffles, wherein the baffles are arranged on both sides of a feeding vibration groove, the two diversion baffles are arranged in the feeding vibration groove, certain ends of the diversion baffles are fixed on the baffles, the other ends of the two diversion baffles are close to each other, a first blanking opening and a second blanking opening which are adjacent are formed along the width direction of the feeding vibration groove, a first flap door and a second flap door are respectively arranged at the first blanking opening and the second blanking opening, and a material dividing baffle which is horizontally arranged along the length direction of the feeding vibration groove is fixedly arranged in the middle of the feeding vibration groove, so as to separate the first blanking opening, the second blanking opening, the first flap door and the second flap door. The utility model aims to provide the material divider for the uniform feeding of the butting machine, by using the material divider, simultaneous operation and uniform continuous feeding of two stem cutters can be realized, the phenomenon of stem head and stem block escape of cut stems is avoided, and the inherent quality of the cut stems of the two stem cutters and the stability of the integral flow are effectively guaranteed.
