[0002] At present, the processing structure of ordinary honeycomb panels is divided into two types: with glue and without glue. The processing process of honeycomb panels with glue usually involves coating the honeycomb core with glue (spraying or pouring glue), and then pressing the metal plate (aluminum plate) on both sides of the honeycomb core under high temperature, and then using a conveying mechanism to send out the honeycomb panel. At present, the mainstream honeycomb panel production lines all use fine steel rollers as the transportation components of the honeycomb panels during the processing process. At the same time, the fine steel rollers can also play a compacting role. Compared with the traditional method of compacting steel plates and then using a conveying mechanism to send them out, this method is more efficient and can complete the compaction during the stepping process. However, this method also has certain problems, such as the problem of uneven force. No matter how fine the steel rollers are, there are still certain gaps, which will cause the honeycomb panel to be unevenly stressed during the compaction process, and may become uneven.

An aluminum coil is wound in the upper aluminum plate unwinding machine 11, and the aluminum plate is output to the upper coiling machine 13 via the upper aluminum plate unwinding machine 11. Under the certain stretching and stepping functions provided by the upper coiling machine 13, it is sprayed with glue by the upper aluminum plate glue spraying machine 15 and then sent to the drying and pressing mechanism for the next step of processing. The lower aluminum plate unwinding machine 12, the lower coiling machine 14, and the lower aluminum plate glue coating machine 16 constitute a raw material output line for outputting the lower aluminum plate. Part of the raw material output line is located outside the processing bracket 9. The lower aluminum plate unwinding machine 12 has an aluminum coil wound in it. The aluminum plate is led out to the lower coiling machine 14 via the lower aluminum plate unwinding machine 12. Under the certain stretching and stepping functions provided by the lower coiling machine 14, it is coated with glue by the lower aluminum plate glue coating machine 16 and then sent to the drying and pressing mechanism for the next step of processing. The honeycomb core discharging line includes a honeycomb core unwinding machine 17, a honeycomb core stretching machine 18, and a honeycomb core glue spraying machine 19. The honeycomb core unwinding machine 17, the honeycomb core stretching machine 18, and the honeycomb core glue spraying machine 19 are sequentially arranged on the suspended platform 91 and located next to the lower aluminum plate glue spraying machine 16. The honeycomb core roll is rolled up in the honeycomb core unwinding machine 17. The honeycomb core is led out to the honeycomb core stretching machine 18 via the upper aluminum plate unwinding machine 11. Under the certain stretching and stepping functions provided by the upper honeycomb core stretching machine 18, it is glued by the honeycomb core glue spraying machine 19 and then sent to the drying and pressing mechanism for the next step of processing. Furthermore, the discharging end of the upper aluminum plate glue spraying machine 15 and the discharging end of the lower aluminum plate glue spraying machine 16 are respectively connected to the feed port of the composite roller press 21, and the discharging end of the honeycomb core glue spraying machine 19 is connected to the feed port of the composite roller press 21.
