摘要
为了实现疏解的单板木束能够呈现纵向纤维不断裂、粗细较均匀的形态,进而为制成强度高、规格大并具有天然木材纹理结构的新型重组木提供优质原料,对重组木辗压疏解机的工作原理进行分析,并在此基础上分析影响单板辗压疏解质量的主要因素,得出单板的辗入基本条件为单板与疏解辊之间的摩擦角φ要大于等于单板的起始抓取角,为α,疏解辊的最大辊压厚度为△B=11.228mm,并对均布加载的单板进行受力分析,为重组木辗压疏解机的设计提供基本理论依据。
In order to produce continuous longitudinal fibers,more uniform thickness of the veneer wood beams, and provide the best quality of raw materials of a high strength, size large and a new recombinant natural wood texture wood, the paper analyzes the basic operating principle of scrimber rolling fluffer and the main factors affecting the quality of the board rolling, the basic conditions are that the friction angle of veneer and relieving roll should be greater initial scraping angle, and the biggest thickness of rolled relief roller is 11.228mm and the stress analysis of well-distributed veneer was done, it provided a theoretical basis for the design of scrimber rolling fluffer.
