[0057] Upper cutting: in the transport process, the lifting motor 14 drives the lifting belt 12 to drive the telescopic arm 10 to expand, and the telescopic frame 7 is lowered to the required position, and the telescopic frame 7 abuts against the bottom plate 6; at this time, the bottom plate 6 on the feeding table 4 has been lifted by the second telescopic driving mechanism 5, and after completing this series of actions, the first telescopic driving mechanism 17 drives the pressing plate 18 to be pressed tightly, the fork knife 22 extends outward from the bottom plate 6, and the pre-prepared board blank layer 2 is smoothly and regularly laid on the bottom plate 6 through the friction force between the board blank layer 2 and the fork knife 22, realizing the automatic upper cutting process of the whole bamboo bundle veneer;

[0058] Board feeding: the telescopic frame 7 starts to rise and retract, and returns to the initial state; the board blank on the bottom plate 6 is checked by manual inspection, and is lowered to the conveying belt 25 by the second telescopic driving mechanism 5, so as to transport the whole bottom plate 6 to the next process; the new bottom plate 6 is transported to the specified position by the conveying belt 25, and the above steps are sequentially and circularly performed, so as to realize the semi-automatic continuous laying of the whole bamboo bundle veneer.
