The invention discloses a multi-layer solid wood floor forming device, which is characterized in that it comprises a conveying mechanism, a plate feeding mechanism, a glue brushing mechanism, a drying mechanism, a vertical groove cutting mechanism, a steering mechanism and a transverse groove cutting mechanism There are nine sets of plate mechanisms, and eight sets of the glue brushing mechanism. The plate feeding mechanism and the glue brushing mechanism are arranged at intervals. According to the conveying direction of the conveying mechanism, the first set of plate feeding mechanisms is located in front of the first set of glue brushing mechanisms. The plate feeding mechanism is installed on the side of the conveying mechanism, the glue brushing mechanism spans above the conveying mechanism, the drying mechanism is located behind the last set of plate conveying mechanism, and the vertical grooving mechanism is located behind the dryer , the steering mechanism is located behind the vertical grooving mechanism, the transverse grooving mechanism is located behind the steering mechanism, and a heater is installed inside the rubber brushing roller of the gluing mechanism. The invention bonds multiple layers of solid wood together without air bubbles at the bonding place, and the glue is evenly applied to prevent the floor from warping, and can operate continuously, thereby improving the forming efficiency.
