Veneer hot-pressing dryer

Abstract

The invention discloses a veneer hot-pressing dryer, which comprises an outer frame, conveying pips, conveying branch pipes and an air blowing device, wherein a fixed hot plate is fixedly arranged atthe top part of the interior of the outer frame, at least one movable hot plate capable of moving up and down in the height direction of the outer frame is further arranged in the outer frame, and a limiting device for limiting the lowest position of the hot plate is arranged between the movable hot plate and the outer frame; an accommodating space is formed between every two adjacent hot plates,and accommodating cavities for accommodating a heating liquid are formed in the fixed hot plates and the movable hot plate; a lifting mechanism is arranged at the bottom part of the outer frame; the conveying pips and the conveying branch pipes are used for conveying the heating liquid, the number of the conveying pips is at least two, and the conveying pipes are connected with the accommodating cavities by means of the conveying branch pipes; and the air blowing device is used for blowing air to the veneer for cooling. The veneer hot-pressing dryer is high in stability, uniform in cooling, low in manufacturing cost, high in automation degree, low in defective rate after veneers are dried, suitable for veneer drying operation, and particularly suitable for veneer drying of a hot-pressing type veneer hot-pressing dryer.

Description

technical field [0001] The invention belongs to the technical field of wood processing equipment, and relates to a veneer hot-press dryer. Background technique [0002] The veneer is a thin board made of wood rotary cutting or planing. It is an important part of the composite board, and its quality directly affects the quality of the composite board. The freshly produced veneer has a relatively high water content, which cannot meet the needs of use. In actual production, the veneer needs to be dried before subsequent operations. The traditional drying method is natural drying, but this drying method not only Inefficient, susceptible to weather, and highly prone to veneer curling. [0003] In order to achieve industrialized high-efficiency drying of veneers, there are many types of veneer drying equipment on the market. Among the existing veneer drying equipment, the veneer drying hot press is the most used. This kind of veneer drying hot press There are multiple hot plates...

AI Technical Summary

Problems solved by technology

The veneer produced by this kind of veneer drying equipment will not be curled, and the production efficiency is high. However, the veneer close to the hot plate will be overheated and the temperature will be too high, resulting in cracking or even carbonization, and the veneer far away from the hot plate will be heated. The drying effect is not good if the temperature is not in place and the temperature is low
