Regeneration multilayer solid wood finger joint plate production method and product

The invention discloses a regeneration multilayer solid wood finger joint plate production method and product; the method comprises the following steps: purchasing waste building construction battens; removing nails and surface impurity; using a right angle edge trimmer to cut heads, classifying the battens according to thickness, and drying the battens; using a comb machine to cut heads and comb; coating glue on a combed tooth flank; using an automatic length expander to splice and expand the length, and cutting the material to a preset length; using a multifunctional multi-blade saw to define width and thickness, and removing surface impurities; using an automatic spreading machine to glue; splicing the material into a mould board in a template, and the template and the mould board are layered and enter a multilayer four-side side-pressure hot press for synchronization hot pressing, thus forming a moulding plate; using a sander to define thickness, flatten, and polish; using a four-side edge trimmer to cut the moulding plate according to preset sizes, thus obtaining plain panels; using an automatic double-face laminator to glue a plurality of plain panels according to different product thickness requirements of a user, overlapping the plain panels into a cold press for cold pressing formation, and using the four-side edge trimmer to cut four edges, thus obtaining the product.
