A paper feeding device is disclosed, and includes a box body, the box body is fixedly provided with a
discharge cavity with an opening facing upward, a left-right symmetrical splint is rotatably arranged on that rear end wall of the
discharge cavity, a plurality of paper cylinders arranged in an arrangement are arranged between the splints, a rotating cavity is communicated with the front end surface of the
discharge cavity, a link rod arrange in that rotating chamber is rotatably arranged on the front end surface of the splint, the connecting rods are rotatably arranged with each other, a movable rod located in the rotating chamber is rotatably arranged with the connecting rod, the movable rod is fixedly provided with an inner cavity with an opening facing downward, and a
vertical bar fixed to the lower end wall of the rotating cavity is slidably arranged with the inner cavity. The device has simple structure and convenient use, and adopts a
cam-type moving mechanism to realize the separation of the paper cylinder, thereby improving the
utilization rate and the paper feeding efficiency of the device, realizing the high-efficiency control of the paper cylinder through a stable ringstructure, and improving the quality of the paper drawing and the reliability of the device.
