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 4, the veneer entering the conveying channels is driven by the first roller 8 to move along the conveying channels, the veneer is irradiated by the laser emitter 61 at the lower part, when holes are formed in the veneer, light rays emitted by the laser irradiator can penetrate through the holes to be sensed by the laser sensing plate 47, and the sensed hole information is fed back to the control module by the laser sensing plate 47;
when the front edge and the rear edge of the hole are in a regular linear shape and no batten is connected between the front edge and the rear edge, the side control module sends an instruction to enable the pressing plate to be pressed downwards, other transmission channels are suspended to drive the transmission channel with the hole only, and meanwhile, the control module converts the distance between the front edge and the rear edge into the number of rotating circles of the output shaft of the motor and sends the number of the rotating circles of the output shaft of the motor to the motor in the corresponding transmission channel, so that the motor rotates corresponding number of circles, and the front single wood plate and the rear single wood plate are attached to each other without gaps;
when the hole is irregular or no wood bar is connected between the front edge and the rear edge, the laser sensing plate 47 feeds the sensed hole information back to the control module, the information includes the initial point of the hole beginning and the end point of the hole ending, when the initial point of the hole moves to the position right below the fixed cutting wheel, the control module sends out an instruction to pause all transmission channels, the driving pressing plate moves downwards and is pressed on the veneer board, the control module controls the moving assembly 15 to move to the position above the transmission channel with the hole, simultaneously drives the cylinder output shaft on the moving assembly 15 to extend out, and simultaneously adjusts the distance between the moving cutting machine and the fixed cutting machine, so that the distance between the two cutting machines is matched with the distance between the initial point and the end point of the hole, the motors of the two cutting machines are driven to rotate, and at the moment, the third motor 42 drives the drill rod 36 to rotate forwards, the second gear 59 drives the outer ratchet ring 63 to rotate reversely, the outer ratchet ring 63 drives the inner pawl disc 64 to rotate, the inner pawl disc 64 drives the transmission rod 38 and the first rotating shaft 67 to rotate, so that the first cutting wheel 35 rotates, when the drill rod 36 rotates forwards, the drill bit 37 at the end part of the drill rod 36 drills into the veneer, the drill bit 37 is a round rod which rises spirally in a spring shape and drives the veneer to rise, the rising veneer is contacted with the first cutting wheel 35 to be cut, and the cut defective veneer is fixed on the drill bit 37;
after cutting is completed, the control module converts the cutting length into the number of rotating circles of the output shaft of the motor and sends the number of rotating circles to the motor in the corresponding transmission channel, so that the motor rotates for the corresponding number of circles, thereby the single wood board at the rear part of the cut section is attached to the single wood board at the front part, meanwhile, the moving component 15 is driven to move towards the limiting plate 32, the cut defect board is positioned in the notch of the limiting plate 32, the defect board is positioned at the lower part of the limiting plate 32 at the moment, the cutting wheel is positioned at the upper part of the limiting plate 32, a gap is reserved between the drill rod 36 and the limiting plate 32, the cylinder output shaft on the moving component 15 is driven to retract, the defect board is positioned at the lower side of the limiting plate 32 at the moment, meanwhile, the third motor 42 drives the drill rod 36 to rotate reversely, when the drill rod 36 rotates reversely, the second gear 59 drives, the first cutting wheel 35 does not rotate, the defect plate positioned on the drill bit 37 is contacted with the lower side of the limiting plate 32 in the ascending process of the drill bit 37, meanwhile, the drill bit 37 rotating reversely can smoothly withdraw from the defect plate, and the defect plate falls into the collecting box at the lower part of the limiting plate 32;
the single wood board entering the second transmission device 23 is continuously gapless, the number of rotation turns of the second motor can be fed back to the control module, when the number of rotation turns of the second motor reaches a set value, the control module sends an instruction to each execution module at the moment to stop the execution of other execution modules, the third air cylinder 18 on the first fixed seat 17 is driven to extend out, the first cutting machine 31 at the end part of the third air cylinder 18 is driven at the same time, the first cutting machine 31 moves downwards while cutting, the pressing block 53 on the first cutting machine 31 is pressed on the single wood board at the moment, the first cutting machine 31 cuts the single wood board in the gap, after the cutting, the control module sends an instruction to enable the first transmission device 2 and the second transmission device 23 to continue to work, the previous complete single wood board enters the upper rubber roller 52, the upper rubber roller 52 performs the gluing on the upper surface and the lower surface of the single wood board, the glued single wood board enters the tightening hole, because the tightening ports are shrunk inwards, gaps between the single boards along the axial direction of the transmission device are compressed, and no gap exists between the single boards along the axial direction of the transmission device;
the seventh motor 68 drives the object placing table 50 to synchronously extend out, so that the extending length of the object placing table 50 can be matched with the length of the single wood board extending out of the gluing roller 52, and when the single wood board entering the second output device is cut, the single wood board extending out of the gluing roller 52 just falls into the object placing table 50, the seventh motor 68 stops working, the output shaft of the seventh motor 68 can freely rotate under the condition of no electric power drive, the object placing table 50 is driven to retreat under the action of gravity without the drive of the first chain 58, the first chain 58 drives the output shaft of the seventh motor 68 to reversely rotate in the retreating process, the inner pawl disc 64 on the output shaft of the seventh motor 68 reversely rotates, the reversely rotating inner pawl disc 64 cannot drive the outer ratchet ring 63 to rotate so as not to drive the gluing roller 52 to rotate, the bottom of the retreated object placing table 50 stops after colliding with the anti-collision plate 44, and all the works are repeated, thereby continuously obtaining the required complete veneer.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the claims of the present invention should not be limited by the above-mentioned embodiments, because the modifications, equivalent variations, improvements, etc. made in the claims of the present invention still fall within the scope of the present invention.
