Background
The wood board is a wood board made of complete wood, and the wood board is a board frequently used in furniture such as wood doors and desks, or tools such as trays. Boards are generally classified by their physical names and do not have a uniform standard specification. When the wood board is processed, if the wood board is used in the field of high-end furniture, a single wood board is generally subjected to cutting, grinding, polishing and other processing; when the pallet is used for processing, two or more wood boards are generally bonded into a whole and then further processed, and the cost of the wood boards obtained by bonding several wood boards is lower than that of a single wood board, so that the cost is saved.
The process of bonding the wood boards is generally: impurities and dust on the surfaces of the wood boards are cleaned, the surfaces of the wood boards are coated with glue, and more than two wood boards are compacted, so that the wood boards can be firmly bonded. The existing process for processing the bonded wood board generally comprises the following steps: a worker brushes the glue solution on the surfaces of the wood boards by using a brush, the wood boards are sequentially stacked and placed on a board pressing machine after the glue solution is brushed, and the plurality of wood boards are compacted by using the board pressing machine, so that the wood boards can be bonded.

The working principle and the beneficial effects of the scheme are as follows:
when the device is required to work, the piston is driven to reciprocate along the piston cylinder. When the piston extrudes the transmission medium in the piston cylinder, the first plunger gradually extends out, the first plunger pushes the wood board of the storage cylinder to the supporting mechanism, the wood board passes through the glue coating mechanism from the lower part in the moving process of the wood board, and the glue coating mechanism coats glue solution on the surface of the wood board. Meanwhile, the second plunger gradually extends downwards, the second plunger drives the pressing plate to move together, and the pressing plate is finally pressed on the wood board of the supporting plate, so that the wood board on the supporting plate is well compacted.
