These are all existing equipment and are not shown in the figure.

[0039] The process for producing lightweight, multi-layer fire-retardant ecological boards using this production line specifically includes the following steps:

[0040] S1. Crush plant straw to prepare flame-retardant and environmentally friendly adhesive;

[0041] S2. The crushed plant straw is mixed and stirred with the prepared flame-retardant and environmentally friendly adhesive through the fiber material mixing system 1 to obtain fiber material, and then the fiber material is conveyed to the upper fiber material laying machine 3 and the lower fiber material laying machine 2 respectively through the fiber material conveyor belt 19.

[0043] S4. The sandwich panel feeding and gluing system evenly coats both sides of the finger joint with flame-retardant and environmentally friendly adhesive, and then places the finger joint on the lower fiber material on the corresponding laying pad after passing through the lower fiber material laying machine 2.

[0044] S5. After the finger joint plate is placed on the lower fiber material, it continues to be conveyed with the laying pad. When it passes the upper fiber material laying machine 3, the upper fiber material laying machine 3 lays the upper fiber material on the finger joint plate.

[0045] S6. Clean the rough edges of the laid lower fiber material, finger joint board and upper fiber material, and then pre-press them through the pre-press machine 4 to form a pre-pressed slab blank.

[0046] S7. Apply a release agent to the pre-pressed slab;

[0047] S8. When the pre-pressed slab is transported to the bottom of the stacker 5 along with the paving pad, the stacker 5 stacks the paving pad carrying the pre-pressed slab on the mold in a predetermined number of layers.

[0048] S9. The stacked pre-pressed slabs are fed into the cold press 6 for cold pressing and mold locking to obtain the shaped slabs.

[0049] S10. Remove the mold;

[0050] S11. Separating the slab: The slab separating machine 7 separates the shaped slab from the paving pad below it, and the mold is returned to the stacking position so that the stacker 5 can stack the paving pad carrying the pre-pressed slab again.

[0052] S13. After the shaped slab is sawn, dried and leveled, and polished, the finished product is obtained. Finally, the finished product is inspected and put into storage.

[0053] In step S12, a separate slab separating machine is used to separate multiple stacked paving mats. The paving mats are continuously placed on the paving mat pusher 9, which pushes them onto the paving mat conveyor roller table 10. The mold release agent application device 12 between the paving mat pusher 9 and the paving mat conveyor roller table 10 applies mold release agent to the passing paving mats. The paving mat conveyor roller table 10 then conveys the mold release agent-coated paving mats onto the paving mat conveyor belt 11, thus allowing the paving mats to be reused.

[0054] The lightweight multi-layer fire-retardant ecological board produced by this production line combines the advantages of both cold-pressed ecological fire-retardant boards and traditional finger-jointed boards. It utilizes the excellent static bending strength and high nail-holding power of finger-jointed boards while retaining the flame-retardant properties of cold-pressed ecological fire-retardant boards. Furthermore, the low density of finger-jointed boards enables lightweight production of finished multi-layer boards, significantly expanding their application range. This production line also achieves automated industrial assembly line production. Compared to existing production lines, this line eliminates the need for separate preparation of each layer. The lower fiber material, finger-jointed boards, and upper fiber material are laid in the laying system according to the laying sequence, with the finger-jointed boards positioned between the lower and upper fiber materials. Pre-pressing followed by cold pressing achieves shaping, eliminating the need for hot pressing and preventing localized deformation of the finished product. This results in high-quality finished products, fewer production steps, a simpler process, significantly shortened production cycle, high production efficiency, and low cost.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
