The invention relates to cement foam board packaging processing equipment and a cement foam board packaging method. The cement foam board packaging processing equipment comprises a supporting bottom plate, linkage push rods, telescopic bottom plates, conveying devices and flattening devices, wherein the left and right ends of the top of the supporting bottom plate are each provided with one groupof linkage push rods, the top of each group of linkage push rods is provided with one telescopic bottom plate, the conveying devices are installed at the tops of the rear ends of the telescopic bottomplates, and the lower ends of the fattening devices are connected with the tops of the front ends of the supporting bottom plates; each flattening device comprises a bearing body, a bearing moving plate, a bearing push rod, a bearing connecting frame, two pushing mechanisms and flattening mechanisms. The cement foam board packaging processing equipment and the cement foam board packaging method can solve the problems that when existing cement foam boards are packaged, corrugated paper cannot be controlled to be automatically fed and needs to be manually placed at a suitable position and manually bent, the corrugated paper can shift when the boards are packaged, and multiple workers need to cooperate to complete positioning of the corrugated paper when the boards are packaged.
