The solid glue net layer can adhere and dredge the veneering surface layer, so that the veneering surface layer is smoothly adhered to the template blank, the veneering surface layer, the solid glue net layer and the template blank can be adhered together by ensuring the permeation of glue, and the veneering surface layer, the solid glue net layer and the template blank can also be used as reinforcing ribs of finished veneering plywood, so that the veneering plywood has more elasticity, difficult deformation and fracture damage. The upper elastic sealing plate, the lower elastic sealing plate and the two sealing baffles are matched to realize that the area between the inner circular arc-shaped cooling plate and the glue fixing net layer is a closed area filled with cold air, so that the cooling effect on glue can be obviously improved, and the energy is saved. Compared with the prior art, the veneer single-layer veneering production line can continuously and smoothly realize single-layer veneering and hot press molding on the template blank, has high degree of mechanization, and has higher strength of the finished veneer veneering plywood.

The concrete structure can be that the horizontal extension portion 2731 and the guide support plate 273 are in transition connection through smooth arc-shaped plates, so that the smoothness of the sliding of the glue fixation net layer 7 and the veneering surface layer 8 is ensured. The concrete structure can be that the upper end of the guide support plate 273 is connected with a flat bearing fixed plate 2722.

Preferably, the conveying production section includes a downstream conveying belt 41 downstream of the cutting platform 31, a list conveying belt 42 downstream of the downstream conveying belt 41, a list running motor for driving the list conveying belt 42, a list carrier 43 for carrying the list conveying belt 42, a list support frame 44 for supporting the list conveying belt 42, and a swing driving device 45 for swing-driving the list carrier 43; the rower belt 42 has an input end corresponding to the downstream belt 41, and an output end corresponding to the first alignment plate; the Row column support 44 is supported at the input end, and the input end is connected with the upper end of the Row column support 44 through a first rotating shaft 46, so that the Row column conveyer belt 42 can be turned over up and down; the swing driving means 45 is a first fluid pressure cylinder supported below the arraying carrier 43, and the upper ends of the arraying carrier 43 and the swing driving means 45 are connected together by a second rotating shaft 47 parallel to the first rotating shaft 46. In the actual working process, after the veneering template blocks reach the conveying production section, the veneering template blocks are continuously conveyed downstream one by the downstream conveying belt 41, when the veneering template blocks reach the rowed conveying belt 42, the rowed conveying belt 42 is driven by the rowed running motor to drive the veneering template blocks to generate a certain speed, meanwhile, under the swinging drive of the swinging drive device 45, the rowed bearing frame 43 drives the rowed conveying belt 42 to swing up and down by virtue of the first rotating shaft 46, and the veneering template blocks fall onto the lower hot pressing plate one by virtue of inertia to be listed.

Preferably, the downstream conveying belt 41 includes a second upstream conveying wheel 411 at the upstream, a second downstream conveying wheel 412 at the downstream, and a second conveying motor that drives the second upstream conveying wheel 411 or the second downstream conveying wheel 412 to rotate. In the actual working process of the invention, the second conveying motor drives the second upstream conveying wheel 411 or the second downstream conveying wheel 412 to rotate so as to realize the conveying function.

The product form of the present invention is not limited to the embodiments and examples shown in the present application, and any suitable changes or modifications of the similar ideas should be made without departing from the patent scope of the present invention.
