[0015] The working principle and beneficial effects of the present invention are: 1. In the present invention, the wooden board is conveyed by the rotation of the transmission roller. During the conveying process, the wooden board will pass through the drying equipment, which will simultaneously dry the upper and lower surfaces of the wooden board, which can effectively ensure that the moisture inside and on the surface of the wood evaporates evenly to avoid uneven drying. At the same time, the push plate moves away from the support plate to push the wooden board toward the middle of the transmission roller to prevent the wooden board from contacting the surface of the support plate during transportation, which may cause the edge of the wooden board to be worn during transportation and affect subsequent sales.

[0016] 2. In the present invention, the up and down reciprocating motion of the sliding block will drive the air pressure plate to reciprocate up and down, and the up and down reciprocating motion of the air pressure plate will squeeze the air inside the air pressure box to be ejected through the air jet port. The gas ejected through the air jet port pre-dries the surface of the wooden board, thereby improving the drying effect. At the same time, the upward movement of the sliding block will drive the connecting plate to move upward, and the upward movement of the connecting plate will push the square plate to rotate upward. The upward rotation of the square plate will drive the rotating rod to rotate upward, and the upward rotation of the rotating rod will drive the rotating plate to rotate upward. The upward rotation of the rotating plate will change the jet range of the air jet port, so that the ejected gas can blow and dry the wooden board comprehensively, thereby improving the drying effect.

[0017] 3. In the present invention, the movement of the trapezoidal plate in the direction away from the pulley will drive the skateboard to move in the direction away from the pulley, and the movement of the skateboard in the direction away from the pulley will drive the brush to move in the direction away from the pulley. The top of the wooden board is cleaned by the brush moving in the direction away from the pulley to prevent impurities from adhering to the top of the wooden board, which will cause the impurities and the wooden board to adhere together during drying and affect the appearance of the wooden board. At the same time, the downward movement of the triangular plate will drive the elastic telescopic plate to move downward, and the downward movement of the elastic telescopic plate will drive the roller to move downward. The downward movement of the roller presses the wooden board downward to prevent the wooden board from warping up and affecting the conveying effect. BRIEF DESCRIPTION OF THE DRAWINGS

9. A drying machine for multi-layer board wood products according to claim 8, characterized in that: The pulley (152) is arranged below the trapezoidal plate (154), and a No. 4 spring is arranged between the air pressure box (142) and the elastic telescopic plate (156).

10. A drying method for a multilayer board wood product drying machine, using the multilayer board wood product drying machine according to claim 9, characterized in that: The following steps are involved: Step 1: The wooden board is driven to be transported by rotating the transmission roller (2). During the transportation of the wooden board, the wooden board passes through the drying device (5). The drying device (5) dries the upper and lower surfaces of the wooden board simultaneously, which can effectively ensure that the moisture inside and on the surface of the wood evaporates evenly, thereby avoiding the phenomenon of uneven drying. Step 2: The transmission roller (2) rotates to drive the fixed rod (7) to rotate, the fixed rod (7) rotates to drive the disc (8) to rotate, the disc (8) rotates to drive the fixed block (9) to rotate, and the fixed block (9) pushes the sliding plate (10) to move upwards during the rotation process; Step 3: the sliding plate (10) moves upwards, driving the short plate (11) to move upwards; the short plate (11) moves upwards, driving the triangular block (12) to move away from the support plate (1); the triangular block (12) moves away from the support plate (1), driving the push plate (13) to move away from the support plate (1); Step 4: The push plate (13) is moved away from the support plate (1) to push the wooden board toward the middle of the transmission roller (2) to prevent the wooden board from contacting the surface of the support plate (1) during transportation, which may cause the edge of the wooden board to be worn during transportation and affect subsequent sales.
