The invention discloses a paper roll clamp with reinforcing plates. The paper roll clamp with the reinforcing plates is characterized in that an external tooth structure is adopted by a turning gear; a gear on an outer ring is meshed with a speed reducer of a hydraulic system, that is to say, the turning gear is connected with the speed reducer in an externally meshed manner; the reinforcing plates are arranged between a long arm assembly and a front bottom plate assembly and between a short arm assembly and the front bottom plate assembly respectively; one ends of the reinforcing plates are fixed to hinge pins, and the other ends of the reinforcing plates extend to the long arm assembly and the short arm assembly respectively; and the ends, located on the hinge pins, of the reinforcing plates are both shaped like a rectangle, the other ends are both shaped like a right triangle, and the right-angle sides of each right triangle are attached to the inner side walls of the long arm assembly and the short arm assembly. The paper roll clamp with the reinforcing plates has the beneficial effects that great improvement can be obtained on vision, the requirement for the force moment of a hydraulic motor is lower, and the reliability and the service life of a whole product are improved.
