The invention discloses a wood chip briquetting device for wood product production, and relates to the technical field of wood product production, the wood chip briquetting device comprises a driving motor, a feeding hopper, a wood chip treatment box, a discharging pipe, a mixing shaft and a rotating shaft, the driving motor is fixedly installed at the center of the top of the wood chip treatment box, and the driving end of the driving motor is fixedly connected with the rotating shaft; and the bottom end of the rotating shaft penetrates through the inner wall of the wood chip treatment box and extends to the inner wall of the wood chip treatment box, and the outer wall of the rotating shaft is fixedly connected with a mixing shaft. According to the device, dust adsorption rods, a dustproof cover plate, an elastic piece, a movable connecting plate and a removing ring are arranged, dust on the surfaces of wood chips can be adsorbed through the dust adsorption rods, and meanwhile after the dustproof cover plate collides with the wood chips, the dustproof cover plate vibrates, so that the dust on the surfaces of the wood chips is removed; and therefore, the elastic piece drives the movable connecting plate and the dust adsorption rod to move, and more dust can be adsorbed.
