At the same time, the negative pressure fan 601 in the negative pressure mechanism 6 is started, and the negative pressure fan 601 evacuates the gas collecting pipe 402 through a pipeline. The solenoid valve 404 controls the evacuation of each vacuum suction cup 406 through a pipeline. When the vacuum suction cup 406 descends onto the veneer in the feeding area 301, the vacuum suction cup 406 adsorbs the veneer. Then the material taking telescopic mechanism 403 retracts, driving the veneer to rise. At the same time, the power mechanism 306 drives the lifting mechanism 305 to rise by the height of one veneer. The driving mechanism 507 rotates in reverse, driving the sliding plate 503, the feeding and adsorption mechanism 4 and the adsorbed veneer to move towards the veneer splicing machine until the veneer is placed on the veneer splicing machine. Then the negative pressure fan 601 stops working, completing the feeding work of a single veneer. How to cycle the operation until all the veneers in the feeding area 301 are fed.

[0040] Then, the feeding telescopic mechanism 308 is activated, and the extending end of the feeding telescopic mechanism 308 retracts, driving the feeding rack 304 to move towards the feeding area 301. During the movement, the feeding rack 304 pushes the veneer on the buffer area 302 to the feeding area 301. Repeat the above operations. Meanwhile, the operator transports the stacked veneer to the buffer area 302 again for standby.
