The invention discloses die-cutting roller equipment and a printing die-cutting device. The die-cutting roller equipment comprises a rack, a rotary roller, an eccentric roller and a phase regulating mechanism, wherein the rotary roller and the eccentric roller are rotatably mounted on the rack; a die-cutting space is formed between the eccentric roller and the rotary roller; the phase regulating mechanism comprises a damping wheel group mechanism and a phase regulating transmission mechanism; the phase regulating transmission mechanism is connected with the rack; the damping wheel group mechanism comprises a first gear and a second gear; the first gear is connected with the phase regulating transmission mechanism; the second gear is in internal engaged connection with the first gear; and the second gear is in nested connection with one end of the eccentric roller. According to the technical scheme adopted by the invention, the die-cutting roller equipment can effectively reduce die-cutting working hours and vibrations generated by the die-cutting roller.
