The usage method adopts a large-format wood planing machine as described above, including the following steps: S1. Insert the wood board to be planed into the inside of the feeding groove from the front end of the feeding groove. Start the motor to drive the upper moving plate to move backward and the lower moving plate to move forward. When the upper moving plate moves backward, the upper one-way roller is locked, pushing the wood board backward into the accommodating groove. At the same time, when the upper moving plate moves backward, the first gear is driven to rotate through the second rack, and then the fifth gear and the planing roller are driven to rotate, planing the bottom of the wood board when the wood board passes through the inside of the feeding groove. S2. When the upper moving plate moves backward, the third gear is driven to rotate through the first rack, and then the threaded rod is driven to rotate. Using the screw structure, the lifting plate is pushed to move upward, transporting the wood board to the top of the lifting plate. When the upper moving plate moves forward, the threaded rod is driven to rotate in the reverse direction, pushing the lifting plate to drive the wood board to move downward. When the lifting plate moves downward, the one-way rack is driven to move downward. The one-way rack drives the second one-way gear to rotate, and then drives the second gear to rotate. The rotation of the second gear drives the fourth gear and the first shaft to rotate 90°. Until the upper moving plate moves forward and resets, the lower moving plate moves backward and resets, and the four second shafts are rotated in turn. S3. When the lower moving plate moves forward, the lower one-way roller gets stuck. The one-way roller pushes the wooden board forward from the top of the lifting plate into the discharge chute. At the same time, the lower moving plate drives the third rack to move forward. The third rack drives the lower first gear and the fifth gear to rotate, and then drives the lower second shaft to rotate, so as to plane the bottom of the wooden board passing through the inside of the discharge chute. S4. When the upper first gear rotates, it drives the ninth pulley to rotate, and then drives the turbine to rotate. When the turbine rotates, a negative pressure is generated inside the housing. Air enters the housing through the air inlet and is discharged through the air outlet pipe, removing the sawdust and dust generated when the second shaft planes the wooden board.

An inlet chute and a discharge chute are respectively arranged above and below the installation groove, and a transfer chute is provided at the tail of the installation groove. A wooden board conveying component is arranged outside the frame. By starting the wooden board conveying component, the wooden board is conveyed from the inlet chute into the transfer chute. While conveying, the bottom of the wooden board is polished. During the reset process of the wooden board conveying component, the lifting component inside the transfer chute is driven to move the wooden board downward. While the wooden board conveying component pushes the wooden board from the inlet chute to the transfer chute again, the wooden board inside the transfer chute is moved into the discharge chute, and the top of the wooden board inside the discharge chute is planed by the rotary planing component. During the downward movement of the lifting component, the rotary planing component is driven to rotate, and the positions of the planing rollers are rotated, so that the upper and lower surfaces of the wooden board can be planed during the continuous wooden board conveying process, improving the planing efficiency, and the planing rollers can be rotated during the planing process to prevent the wooden board surface from leaving char marks due to overheating friction of the planing rollers during continuous planing, and it is more suitable for continuous planing operation of large-format wooden boards.

The eighth pulley 520a is connected to the ninth pulley 530 by a belt. When the upper moving plate 230 moves backward to drive the first gear 160 to rotate, the first gear 160 drives the first one-way gear 160a to rotate. The first one-way gear 160a drives the third one-way gear 530a and the ninth pulley 530 to rotate. The ninth pulley 530 drives the eighth pulley 520a and the turbine 520 to rotate by a belt. When the turbine 520 rotates, a negative pressure is generated inside the housing 510. Air enters the inside of the housing 510 through the air inlet 510a and is discharged through the air outlet pipes 510b-1. The air discharged from the air outlet pipes 510b-1 blows away the wood chips, dust, etc. generated during polishing.
