Description

Technical Field

[0001] The utility model relates to the technical field of door production and manufacturing, in particular to a door panel preparation and gluing line. Background Art

[0002] Plywood is an important part of the door processing process. In the production process, the wood blocks are first cut into veneers, and then glued together. At the same time, according to the thickness, the number of plywood layers is set to three, and some can reach more than ten layers. Generally speaking, they are stacked according to odd numbers so that the adjacent two layers are reproduced in a vertical state, and the physical properties of this plywood are relatively stable.
