Hot melt adhesive film composite spliced veneer and plywood production process applying same

Abstract

The invention relates to a hot melt adhesive film composite spliced veneer, which comprises a plurality of veneers spliced together, wherein a joint between every two adjacent spliced veneers is stuck by multiple points of hot melt adhesive, and a layer of hot melt adhesive film is stuck on certain side faces of every two adjacent spliced veneers. The invention also relates to a production process which applies the hot melt adhesive film composite spliced veneer to produce plywood. Production processes for the plywood are completely changed, the hot melt adhesive film composite spliced veneers which are prepared in advance are utilized as adhesive-applied veneers and are hot-pressed to form the plywood after being superposed, the production efficiency is greatly increased, the veneer arrangement precision is increased, the veneer arrangement gap is reduced, the quality of the plywood is increased, traditional processes in which plywood production basically depends on manual work are got rid of, and the realization of plywood production automation becomes possible.

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...
