After the rectangular frames 702 on each group are abutted against the outer side of the heat preservation board, with the continuous driving of the transmission plate 701, the transmission plate 701 moves towards the rectangular frame 702. During the movement, the strip plate 703 is pushed by the connecting rod 705. During the pushing process, the triangular support blocks 704 on each group are inserted into the edge gaps between the aluminum honeycomb core board 103, the decorative board 101, and the back plate 102.

[0073] After the support, the lifting platform 301 is driven to move downward through the lifting component and the guiding component. Through the downward movement of the lifting platform 301, the pressing plate 302 abuts against the heat preservation board. Through the abutting and extrusion action and maintaining for a period of time, the purpose of cold pressing is achieved.
