双动刀环式刨片机是刨花板备料工段不可或缺的装备之一,随着刀环宽度的增加,双动刀环式刨片机刀环宽度方向磨损不均匀问题越加明显。根据阻挡分流原理设计一种双8字形分料装置,主要由一次分料板、二次分料板、连接杆和传动轴组成。通过计算流体动力学(computational fluid dynamics,CFD)分析双8字形分料装置的分料翼板弯折角度和分料装置转速对木片运动轨迹的影响,结果表明该分料装置的应用可以使木片在刀环宽度方向上分布均匀,有助于解决刀环磨损不均匀的问题。研究结果可为双动刀环式刨片机的结构改进提供理论依据与技术支撑。
Double drum knife ring flaker is one of the indispensable equipment for material preparation section of particleboard production. When the width of the knife ring increased, uneven wearing loss in the width direction of the knife ring of the double drum knife-ring flaker became significantly. According to the principle of blocking and diverting, a dividing device with a shape of double 8 was designed, which was mainly composed of a primary dividing plate, a secondary dividing plate, a connecting rod, and a driving shaft. The effects of the bending Angle of the dividing wing and the speed of the dividing device on the motion trajectory of the wood chip were analyzed by computational fluid dynamics (CFD). The results showed that the installation of the dividing device make the wood chip distribute evenly in the width direction of the knife ring, which is helpful in solving the problem of uneven wearing loss of the knife ring. The research results provide a theoretical basis and technical support for the development of the double drum knife ring flaker.
