This utility model relates to the technical field of furniture processing, and in particular to a board soaking device for furniture processing. By setting up this device, it can ensure that each board can be evenly contacted with the solution, and can guarantee the concentration of the soaking solution, thereby improving the soaking effect. It includes a soaking tank, a wire mesh frame, multiple sets of wire mesh partitions, multiple sets of adjusting blocks, multiple sets of bolts, a lifting device, a pressing device, and a stirring device. The bottom of the soaking tank is provided with four sets of support legs. The multiple sets of wire mesh partitions are movable within the wire mesh frame. The front end of the wire mesh frame is provided with an elongated hole. The multiple sets of adjusting blocks are respectively installed at the front end of the multiple sets of wire mesh partitions and slide within the elongated hole of the wire mesh frame. The top and bottom of the multiple sets of adjusting blocks are provided with threaded holes. The multiple sets of bolts are threadedly connected to the threaded holes of the multiple sets of adjusting blocks and are engaged with the wire mesh frame. The lifting device is installed at the rear end of the soaking tank and is connected to the wire mesh frame. The stirring device is installed in the lower part of the soaking tank.

The invention discloses a method for improving the surface functionality of low-density wood. The method comprises the following steps that (1) the low-density sawn timber is dried till the water content reaches 10%-15%, then wire drawing treatment is conducted on the tangent plane or the tangential plane of the low-density sawn timber, and the low-density sawn timber with the three-dimensional natural texture and machining residues are obtained; 2) grinding and drying the processing residues to obtain wood powder, mixing the wood powder with water, then putting the mixture into a hydrothermal reaction kettle for reaction, then filtering a reacted system, and taking filtrate to obtain a carbon quantum dot solution; 3, the low-density sawn timber with the three-dimensional natural textures is soaked in the carbon quantum dot solution, then drying treatment is conducted, and low-density wood surface functional improvement is achieved.The three-dimensional natural textures are improved through physical treatment, the processing residue pretreatment solution serves as a modifier, and the apparent strength of the wood surface can be improved.
