The invention provides a smooth full-automatic plywood hot press production line. According to the production line, mold plate blanks are subject to non-interrupted continuous smooth hot pressing forming, the structure form of a traditional plywood hot press is broken, in the actual work process, under control of a total controller, a brush coating production line segment brushes glue on the moldplate blanks, brush coating mold plate blanks are formed and are conveyed to the hot pressing production line segment, a supply production line segment conveys a partition layer and the mold plate blank on the uppermost layer to the hot pressing forming production line segment, the mold plate blank on the uppermost layer is cushioned on the upper portion of brush coating mold plate blocks with thecorresponding number to serve as a surface layer, the partition is cushioned on the upper portion of the corresponding mold plate blank on the uppermost layer to enable the uppermost mold plate blankon the upper portion and the multiple brush coating mold plate blocks to be separated from the uppermost mold plate blank on the lower portion and the brush coating mold plate blocks, finally, hot pressing forming is carried out through the hot pressing forming production line, and multiple pieces of plywood can be formed at a time.
