Problems solved by technology

[0002] At present, the process of using hot-melt adhesive film and veneer to produce plywood is to lay out a layer of veneer on the laying line, then spread the adhesive film, then lay out a layer of veneer, and then lay a layer of adhesive film..., U-shaped plastic nails need to be fixed between adjacent two-layer veneers. This kind of production technology is backward, requiring many people, low efficiency, unstable product quality, and high labor intensity

Embodiment Construction

[0023] Such as Figure 1~7 As shown, a hot-melt adhesive film composite splicing veneer includes a plurality of veneers 1 spliced ​​together, and the seams between two spliced ​​adjacent veneers 1 are bonded to each other by multi-point hot-melt adhesive 2 Together, it also includes a layer of hot-melt adhesive film 3 bonded to one side of all the veneers. The hot-melt adhesive film 11 is made of formaldehyde-free film-like wood adhesive. Cut out the required specifications, and then make plywood by superimposing hot-pressing and cold-pressing on the multi-layer hot-melt adhesive film composite splicing veneer, which can greatly improve the processing efficiency, and can avoid the serious influence of excessive splicing seams and overlapping in the traditional process on plywood The downside of quality.

[0024] In this embodiment, the veneers are spliced ​​horizontally or spliced ​​vertically according to the direction of the wood grain.

[0025] Such as Figure 4 As shown...

Abstract

Single boards combined and bonded by a hot-melt adhesive film comprise multiple single boards (1) joined together. Two adjacent joined single boards are adhered together by applying multiple hot-melt adhesive points (2) to a seam therebetween. A hot-melt adhesive film is adhered to one side surface of the two adjacent joined single boards. Also provided is a plywood manufacturing process employing the above single boards combined and bonded by a hot-melt adhesive film. Compared with existing plywood manufacturing processes, the invention stacks single boards combined and bonded by a hot-melt adhesive film in advance, and then performs hot pressing to form a plywood, thereby increasing productivity and alignment precision, reducing a gap between single boards, improving quality of a plywood, and realizing automatic manufacturing of plywood.

Description

technical field [0001] The invention relates to a hot-melt adhesive film composite splicing veneer and a plywood production process using the same. Background technique [0002] At present, the process of using hot-melt adhesive film and veneer to produce plywood is to lay out a layer of veneer on the laying line, then spread the adhesive film, then lay out a layer of veneer, and then lay a layer of adhesive film..., U-shaped plastic nails need to be fixed between adjacent two-layer veneers. This kind of production technology is backward, employs many people, has low efficiency, unstable product quality, and high labor intensity. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a hot-melt adhesive film composite splicing veneer and a plywood production process using the same, which can reduce the gap between the boards and greatly improve the production efficiency of the plywood. [0004] The present invention adopts t...
