Insulation board continuous lifting and feeding device

A lifting frame is arranged in a ground groove, a plate conveying frame is arranged on the upper portion of the lifting frame, and the lifting frame and the plate conveying frame are matched to achieve layer-by-layer conveying of heat preservation plates. A feeding frame is arranged on the rear side of the plate conveying frame, and a conveying device is arranged on the feeding frame so that the heat preservation plates can be conveyed from the plate conveying frame to the cutting equipment. A lifting frame is arranged on the periphery of the feeding frame, a plurality of vertical chains are arranged on the lifting frame, lifting supporting rods are evenly distributed on the vertical chains, and when the vertical chains move vertically, the lifting supporting rods arranged on each layer jointly achieve horizontal lifting of the heat preservation plate. When the feeding frame stops feeding to the cutting machine, the vertical chain in the lifting frame vertically moves to lift the heat preservation plates on t
