The invention relates to the technical field of wood processing, and discloses an intelligent cutting device for wood processing. The intelligent cutting device for wood processing comprises a machinecabinet, wherein a workbench is arranged at the upper end of the machine cabinet, a cutting blade is arranged in the middle of the upper surface of the workbench, a limiting transverse plate is arranged on one side, close to the cutting blade, of the upper surface of the workbench, a fixing seat is arranged at the position, below one end of the limiting transverse plate, of the front surface of the workbench, a reflecting plate is fixed at the position, corresponding to the cutting blade, of the front surface of the workbench, and an infrared range finder is embedded at the position, corresponding to the reflecting plate, of one side surface of the fixed seat. According to the intelligent cutting device, the distance between the limiting transverse plate and the cutting blade is intelligently adjusted, so that the tedious problem that due to the traditional wood cutting size, wood is cut after being manually measured is solved, the wood cutting efficiency is further improved, the operation is simple and convenient, the cutting accuracy is high, meanwhile, the intelligent automatic measurement is realized, the complexity of manual measurement is saved, and the measurement accuracyis also improved.
