The working principle of the invention is as follows: the first conveying device 2 is long enough, the veneer is pushed into the first conveying device 2, the veneer enters respective conveying channels after being cut by the second cutting wheel 55, the veneer entering the conveying channels is driven by the first roller 6 to move along the conveying channels, the veneer is irradiated by the laser emitter 58 at the lower part, when holes are formed in the veneer, light rays emitted by the laser emitter 58 can penetrate through the holes to irradiate the laser sensing plate 71, and the laser sensing plate 71 can feed sensed hole information back to the control module;

when a hole passes through the laser emitter 58, the laser passing through is sensed by the laser sensing plate 71, the laser sensing plate 71 feeds back the initial point and the end point of the sensed hole to the control module, when the initial point of the hole moves to the position right below the fixed cutting machine, the control module sends out an instruction to pause all transmission channels, the control module controls the moving assembly 12 to move to the position above the transmission channel with the hole, simultaneously drives the output shaft of the second air cylinder 14 to extend out, drives the second screw 47 to rotate through the sixth motor 46 so as to adjust the distance between the moving cutting machine and the fixed cutting machine, so that the hole is positioned between the fixed cutting machine and the moving cutting machine, the distance between the fixed cutting machine and the moving cutting machine is the width of the n filling plates, drives the second motor 45 to rotate, the second motor 45 drives the drill rod 49 to rotate in the forward direction, and the first gear 75 drives the outer ratchet ring 76 to rotate in the reverse direction, the outer ratchet ring 76 drives the inner ratchet disc to rotate, the inner ratchet disc drives the transmission rod 51 and the first rotating shaft 52 to rotate, so that the first cutting wheel 48 rotates, when the drill rod 49 rotates in the forward direction, the spring drill 50 drills into the veneer to drive the veneer to ascend, the ascending veneer is contacted with the first cutting wheel 48 to be cut, and the cut defective veneer is left on the spring drill 50;

after cutting, the fixed cutting machine and the movable cutting machine are driven to move into the notch of the limiting plate 42, the defective plate is positioned at the lower part of the limiting plate 42, the first cutting wheel 48 is positioned at the upper part of the limiting plate 42, a gap is reserved between the drill rod 49 and the limiting plate 42, the output shaft of the second air cylinder 14 is driven to retract, so that the defective plate is abutted against the lower part of the limiting plate 42, and simultaneously drives the second motor 45 to drive the drill rod 49 to rotate reversely, when the drill rod 49 rotates reversely, the first gear 75 drives the outer ratchet ring 76 to rotate in the forward direction, the inner ratchet disc does not rotate when the outer ratchet ring 76 rotates in the forward direction, the first cutting wheel 48 does not rotate, the defective board on the spring drill 50 is contacted with the lower side of the limit plate 42 during the ascending process of the spring drill 50, meanwhile, the spring drill 50 rotating reversely can smoothly withdraw the defective plate, and the defective plate falls into the collection box at the lower part of the limiting plate 42;

when the cut single wood boards enter the second conveying channel and the distance between the front single wood board and the rear single wood board is long enough, the stop block 21 presses downwards to block the front ends of the single wood boards in different conveying channels, so that the single wood board at the rear part of the defective board is connected with the single wood board at the front part, and the connected rear baffle is lifted;

when the cut veneer is stopped and aligned by the stop, the conveyor 59 of the second conveyor 15 is halted, the alignment device is moved to the front end of the cut veneer, the first cylinder 27 is actuated, the output shaft of the first cylinder 27 extends to push out the filling plate in the box 18, the first connecting rod 26 drives the first rotating plate 25 to rotate while the filling plate is pushed out, the first rotating plate 25 drives the telescopic part 24 of the telescopic rod to stretch and rotate, the telescopic rod body 23 drives the roller brush 79 to rotate, the roller brush 79 is soaked with glue, the roller brush 79 is contacted with the front edge of the completion plate so as to be capable of coating the glue on the front edge of the completion plate, the completion plate is pushed out to retreat against the single wood plate to be cut, the number of the completion plates sequentially pushed out is matched with the length of the defect plate to be cut, then, the cut single wood boards in different transmission channels are supplemented through the movable supplementing device;

the supplemented single wood boards are contacted with a tightening device, the supplemented single wood boards are extruded when passing through the tightening device, the single wood boards in different transmission channels are tightly attached after being extruded, and gaps do not exist among the single wood boards in different transmission channels, so that the single wood boards in different transmission channels form a complete single wood board;

the complete veneer enters the gluing roller 31, and the gluing roller 31 glues the upper surface and the lower surface of the veneer;

the third motor 62 is shared by the gluing roller 31 and the object placing table 67, so that the extension length of the object placing table 67 can be matched with the length of the single wood board extending out of the gluing roller 31, and when the single wood boards entering the second output device are supplemented, the single wood boards extending out of the gluing roller 31 just fall into the object placing table 67, at the moment, the second motor 45 stops working, the output shaft of the second motor 45 can rotate freely under the action of no electric energy, the object placing table 67 returns under the action of gravity, the output shaft of the second motor 45 rotates reversely, the inner pawl disc 77 on the output shaft of the second motor 45 rotates reversely, the inner pawl plate 77 cannot drive the outer ratchet ring 76 to rotate reversely so as not to drive the gluing roller 31 to rotate reversely, the retracted placement table 67 stops after the bottom collides with the anti-collision plate 41, and all the work is repeated, so that a complete veneer meeting the requirements can be continuously obtained.
