Veneer dryer

Abstract

The invention discloses a veneer dryer which comprises a plurality of heating plate groups and a plurality of transmission drum groups that are arranged in a planar continuous alternation manner; each heating plate group comprises an upper heating plate and a lower heating plate; a distance between each upper heating plate and each lower heating plate is greater than the thickness of veneers; each transmission drum group comprises an upper drum and a lower drum that are arranged relatively vertically, are opposite in rotation direction and are used for clamping and conveying the veneers; and a center distance between every two adjacent transmission drum groups is less than the length of the side, parallel to a conveying direction, of each veneer. According to the veneer dryer, the upper heating plates and the lower heating plates dry the veneers from the upper sides and the lower sides; since the upper heating plates and the lower heating plates are fixed, no air flows; a heat utilization rate is increased; the drying efficiency is high; the veneers is extruded by the upper drums and the lower drums; the evenness of the veneers is improved; since the heating plate groups and the transmission drum groups are arranged in a planar manner, the veneers cannot be bent; and a proportion of the broken veneers is decreased.

Description

technical field [0001] The invention relates to the technical field of wood-based panel processing and manufacturing, in particular to a veneer dryer. Background technique [0002] Wood-based panels are widely used in architectural decoration, furniture industry, packaging boxes, cargo pallets, storage boxes, and container industries, and are an important way to save wood resources. Wood-based panels refer to wood or other non-wood plants as raw materials, which are processed into component materials of various shapes such as veneers, shavings or fibers, and are recombined with (or without) adhesives and other additives. Panels mainly include three major categories of products: plywood, particle (particle) board and fiberboard. Wherein, in the process of processing raw materials into veneers, the veneers need to be dried and pressed to make them flat. [0003] In order to dry the veneer, a veneer dryer is provided in the prior art, such as figure 1 As shown, it includes t...

Problems solved by technology

However, this dryer adopts the method of drying one side of the veneer, the drying efficiency is low, and the water volume after the veneer is dried is not uniform, which affects the drying effect, and the movable hot platen will drive the flow of air during the process of movement, so that Heat is lost to the air, resulting in a waste of energy
