[0027] The working principle of the present utility model is as follows.

[0028] (1) Before work, rotate the handwheel on the rotating rod 706 according to the thickness of the wooden board 3. The handwheel drives the second sprocket 708 to rotate through the rotating rod 706, and the second sprocket 708 drives the first sprocket 703 to rotate through the first chain 704, thereby realizing the synchronous rotation of the second lifting screw 707 and the first lifting screw 702. The rotation of the second lifting screw 707 and the first lifting screw 702 drives the lifting plate 701 to lift, thereby adjusting the distances between the rear pressure roller 713, the front pressure roller 714 and the planing tool 719 and the wooden board 3.

[0029] (2) Place multiple wooden boards 3 to be processed on the conveyor belt 401. Then, start the conveyor belt motor 406. The conveyor belt motor 406 drives the third driving wheel 410 to rotate. The third driving wheel 410 drives the first driving wheel 404 to rotate through the transmission belt 405. The first driving wheel 404 drives the first gear to rotate through the second gear. The first gear drives the second driving wheel 407 to rotate. The second driving wheel 407 drives the conveyor belt 401 to move, thereby driving multiple wooden boards 3 to move towards the side extrusion cylinder 605. At the same time, start the aligning cylinder 602. The aligning cylinder 602 drives the aligning plate 604 to descend. When multiple wooden boards 3 contact the aligning plate 604, the front ends of multiple wooden boards 3 are aligned under the action of the aligning plate 604. Then, start the pressing cylinder 601 and the side extrusion cylinder 605. The side extrusion cylinder 605 drives the clamping plate to move and clamps the sides of multiple wooden boards 3 through cooperation with the clamping plate on the workbench 402. When multiple wooden boards 3 move, the clamping plate on the side extrusion cylinder 605 and the clamping plate on the workbench 402 move simultaneously with the wooden boards 3. The pressing cylinder 601 drives the pressing plate 603 to descend and clamps the upper parts of multiple wooden boards 3 through the pressing plate 603. Then, stop the conveyor belt motor 406. Subsequently, the side extrusion cylinder 605 drives the clamping plate to return to its original position, the pressing cylinder 601 drives the pressing plate 603 to return to its original position, and the aligning cylinder 602 drives the aligning plate 604 to return to its original position.

[0030] (3) Start the workbench driving motor 409. The workbench driving motor 409 drives the third gear to rotate. Under the action of the rack, the third gear rolls along the rack. At the same time, the workbench driving motor 409 slides along the workbench guide rail 408. The workbench driving motor 409 drives the workbench 402 to slide along the workbench guide rail 408. The workbench 402 drives the conveyor belt 401 to move synchronously. At the same time, start the cutter roller motor 705. The cutter roller motor 705 drives the fourth sprocket 718 to rotate. The fourth sprocket 718 drives the third sprocket 710 to rotate through the second chain 709. The third sprocket 710 drives the planing part of the planer knife 719 to plane the upper surface of the wooden board 3, and presses it through the front pressing roller 714, the rear pressing roller 713 and the bulletproof plate 717 to prevent the wooden board 3 from bouncing up and causing processing failure. The planed wooden board 3 moves to the next process through the workbench 402.
