Description

Technical Field

[0001] This utility model belongs to the field of plywood processing technology, and in particular relates to an automatic plywood stacking machine. Background Technology

[0002] Plywood is a sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets, and then gluing them together with adhesives to form three or more layers. The number of layers is generally odd, but a few may have an even number. Typically, adjacent layers are glued together with their grain directions perpendicular to each other, ensuring the fiber directions of the veneers are perpendicular. Plywood is a commonly used material in furniture making and is also used in aircraft, ships, trains, automobiles, construction, and packaging. The plywood production process requires the use of stacking machines to stack the boards.
