The invention relates to an alignment cutting device of wood plates, in particular to an alignment cutting device of wood plates for architecture. In order to achieve the technical aims, the alignmentcutting device of the wood plates for architecture is high in cutting speed, can achieve alignment cutting during wood plate cutting, can treat dust during cutting and can collect wood scraps. To achieve the above technical aims, the alignment cutting device of the wood plates for architecture comprises an n-shaped support, a foot stand and the like; the n-shaped support is arranged on the ground; a containing plate is arranged above the ground; the foot stand is arranged at the bottom of the containing plate; the containing plate is located on the n-shaped support and provided with a linearhole; and a moving device is arranged at the inner top of the n-shaped support. The alignment cutting device achieves the effects that the cutting speed is high; alignment cutting can be achieved during wood plate cutting; the dust can be treated during cutting; the wood scraps can be collected; electric drive is adopted by the device; the force cutting efficiency is improved; alignment cutting can be carried out on the wood plates effectively; and air pollution can be avoided.
