Description

Plywood hot press

Technical Field

The invention relates to the technical field of hot pressing of plywood, in particular to a plywood hot press.

Background

The plywood is a three-layer or multi-layer plate material formed by rotary cutting wood sections into single boards or slicing wood blocks into thin wood and then gluing the single boards by using an adhesive, and is usually formed by gluing odd-number layers of single boards and mutually vertical fiber directions of the single boards of adjacent layers.

The plywood is one of the common materials for furniture, is one of three large plates of an artificial plate, and can also be used as a functional material for airplanes, ships, trains, automobiles, buildings, packing boxes and the like. A group of veneers are typically assembled and glued perpendicular to each other with the grain direction of adjacent layers, and the skins and inner sheets are typically symmetrically disposed on either side of the core or core. The glued veneer is pressed into the wood grain board blank by the criss-cross matching of the glued veneer according to the wood grain direction under the condition of heating or not heating. The number of layers is generally odd, and a few are even. The difference of physical and mechanical properties in the longitudinal and transverse directions is small. The types of plywood commonly used are plywood, plywood and the like. The plywood can improve the utilization rate of the wood and is a main way for saving the wood.

Need carry out the hot pressing to the plywood when production plywood, the atress is uneven between the adjacent plywood when production of current hot press, leads to the plywood hot pressing effect poor, the quality unstability. To this end, we propose a plywood hot press.
