The invention discloses a roller bed system. The roller bed system comprises power roller bed bodies arranged in a segmented manner. The end portions of the power roller bed bodies can be connected and fixed in an end-to-end manner. Each power roller bed body comprises a base playing a supporting role, wherein conveying bins are arranged on the two sides of the base in the length direction correspondingly. Transmission shafts are rotationally arranged in the conveying bins in the length direction and sleeved with driving bevel gears. Conveying wheels are rotationally arranged in the conveying bins, and driven bevel gears arranged on the conveying wheels are engaged with the driving bevel gears for transmission. Each base is further provided with a rotation device, wherein the rotation device drives the corresponding transmission shafts to rotate so as to drive trays placed on the corresponding conveying wheels to move. According to the roller bed system, a segmented structure is adopted, the segments of structures are fixed into the integral roller bed for conveying during using, assembling of different forms can be achieved according to actual situations, and the roller bed conveying convenience is improved. Power of the rotation devices is transmitted to the conveying wheels through the transmission shafts, and only one rotation device needs to be arranged in each power roller bed body for driving the multiple sets of wheels to run.
