Abstract: The present application provides an automatic non-woven fabric laying device. The device includes a non-woven fabric lifting mechanism, traction manipulators, a cutting manipulator, guide rollers, guide plates and the like. By recognizing the width and diameter parameters of a hub, the non-woven fabric lifting mechanism and the traction manipulators respectively adjust the height, the traction manipulators adjust the traction length of a non-woven fabric, and the cutting manipulator cuts the non-woven fabric after the length of the non-woven fabric is determined, thereby completing automatic laying of the non-woven fabric.
