When transporting the veneer, the inlet and outlet parts use chains, which are prone to extrusion, causing indentations and loss. When shearing, it usually passes through the extrusion of the straightening sprocket. When the veneer is thin, it is too soft and easily squeezed into the sprocket, which also causes loss, and the flatness of the veneer is difficult to guarantee. Utility Model Content

[0009] Preferably, the width of the auxiliary tube is smaller than the width of the adsorption tube, a conveying wheel is provided on each side of the adsorption tube, and the two conveying wheels are located on the same side of a transition plate.

[0010] Preferably, the auxiliary pipe extends to the middle of the loading plate and is located on the side of the vertical axis of symmetry of the rotating shaft close to the adsorption pipe.

[0011] Preferably, the adsorption support assembly is provided with a long hole on the transition plate at one end of the incoming material, and the transition plate is hinged with a baffle in the long hole and hinged to the middle part of the baffle, and the lower end of the baffle is connected to a transmission assembly for pushing the lower end of the baffle to rotate the upper end of the baffle and extend out of the long hole.
