The working principle of the invention is as follows: firstly, adding an anticorrosive agent into the reagent barrel 223, then driving the third servo motor 210 to work, driving a plurality of conveying rollers 22 to rotate through a gear set, inputting the wood products from the conveying port 11, and driving the wood products into the box body 1 by the conveying rollers 22 so as to convey the wood products conveniently; then, the first servo motor 25 and the second servo motor 26 are driven to work, the second screw rod 23 and the first screw rod 29 are respectively driven to rotate, the second screw rod 23 drives the two second clamps 28 to move relatively, the first screw rod 29 drives the first clamp 27 to move relatively, and therefore, wood products are fixed, the wood products with different sizes can be conveniently fixed, the practicability is high, and subsequent coating is convenient; then, the two fourth servo motors 220 are driven to rotate, so as to drive the primary synchronous belt pulley 211 to rotate, the primary synchronous belt pulley 211 drives the secondary synchronous belt pulley 216 to rotate through the synchronous belt 214, so as to drive the sliding block 212 to slide on the synchronous belt 214, and drive the two sliding rails 225 to slide relatively on the sliding bar 215; meanwhile, the fifth servo motor 222 is driven to work to drive the main belt pulley 218 to rotate, the main belt pulley 218 drives the auxiliary belt pulley 219 to rotate through a belt, the auxiliary belt pulley 219 drives the third screw rod 226 to rotate, the slide block 224 is driven to move, the slide block 224 drives the reagent barrel 223 to move, and the anticorrosive agent is sprayed on the wooden products through the spray head 221; the reagent barrel 223 moves in the X-axis direction and the Y-axis direction, so that the anticorrosive agent can be conveniently and uniformly sprayed on the wooden products, and the humidity wooden products have better anticorrosive property;

finally, the air cylinder 32 is started, the piston rod drives the U-shaped plate 33 to move, the leveling roller 34 is further driven to move, and the anticorrosive agent on the surface of the wood product is coated flatly, so that the anticorrosive agent is more uniform and better in corrosion resistance, and redundant anticorrosive agent is collected by the collecting tank 4, so that the anticorrosive agent is convenient to recycle, energy-saving and environment-friendly; can process two woodwork simultaneously, provide work efficiency.
