The utility model relates to the technical field of printers, and specifically relates to an automatic loading and unloading floor printing machine. It comprises: a frame; a transmission mechanism extended along the distribution direction of the frame and used for transporting the floor; an automatic printing mechanism set on the frame and used for positioning and printing the floor; a loading mechanism set on the frame and located at one end of the printing mechanism, the loading mechanism used to transfer the floor placed on the loading mechanism to the transmission mechanism in turn; and, a discharging mechanism set on the frame and located at the other end of the printing machine the lowering mechanism, the lowering mechanism is used to move the floors on the transferring mechanism to the lowering mechanism. The utility model stacks the floor on the loading mechanism, the loading mechanism automatically loads the floor, the transmission mechanism automatically transports the floor, the automatic printing mechanism automatically sprays the floor, and the discharging mechanism automatically discharges the floor, which improves the automation degree of the floor spraying process, and reduces the burden of the staff.
