The invention discloses a pressing and stacking device of a plate for intelligent processing. The device comprises a hydraulic cylinder, a pressure detection box, a pressing and stacking equipment box, a drying box, a transmission box, a support, a bottom plate, a motor and a bearing and supporting table, wherein supports are fixedly installed at the parts, located in and close to four corners, of the top of the bottom plate, the transmission box is fixedly installed at the tops of the supports, the transmission box is a rectangular box body, a cavity is formed in the transmission box, a sliding groove is formed in the top of the transmission box, and a threaded rod is rotationally installed in an inner cavity of the transmission box; and the right side of the threaded rod is rotationallyinstalled on an inner wall bearing seat of the transmission box, the left side of the threaded rod penetrates to the outside of the transmission box, and the threaded rod is located on the transversecentral axis of the transmission box. The pressing and stacking device of the plate for the intelligent processing is novel in design, the integration degree is high, a composite board is pressed andstacked through a pressing and stacking roller, and therefore a board surface is stressed uniformly, accurate control of the down pressing force can be carried out, so that the pressing and stackingquality is greatly improved, and the working efficiency is improved.
