The invention discloses a wood floor veneering machine. The wood floor veneering machine structurally comprises a flatten shell removing device, a control panel, a main body, supporting legs, supporting rods and a conveying frame, wherein the flatten shell removing device is electrically connected with the control panel through a wire, the back face of the control panel is nested on the main body,and the inner surface of the main body is attached to the outer surface of the conveying frame in a fit mode; the back faces of the supporting legs are connected with the front ends of the supportingrods in a welded mode, the supporting rods are parallel to the conveying frame, and the lower part of the conveying frame is connected with the upper ends of the supporting legs in a welded mode. According to the machine, the flatten shell removing device comprises a voltage rotating device, a chip removing mechanism, a linkage device, a shell discharging device, a pressing and flattening mechanism, a fixed-point reciprocating device and a veneering temperature-increasing device, so that the surface of a wood floor is enabled to be subjected to chip removing before veneering is carried out, and the flatness of the surface of the wood floor is improved; and formaldehyde contained in the wood floor can be dissipated in an accelerated mode while the veneering is carried out, the waiting forthe later period engineering is avoided, the working time is greatly shortened, and workers are prevented from being in contact with the formaldehyde for a long time.
