摘要

光辊机构作为瓦楞机上的关键机构之一,对瓦楞原纸和芯纸的粘合起到关键性的作用,而光辊的振动,不仅影响瓦楞纸板的成型质量,而且降低了瓦楞机的使用寿命,也产生了很大的噪声。本文以光辊简化机构模型为基础建立数学模型,运用拉格朗日函数方程进行求解,得到光辊机构的固有频率,为光辊机构优化提供理论依据,然后对光辊机构进行振动测试,验证数学模型的正确性,最后改变影响光辊机构固有频率的因素,提高固有频率,避免共振。

Abstract

Pressure roller mechanism is one of key mechanisms in a corrugating machine. It plays an important role in bonding corrugated base paper and core one. The vibration of pressure rollers not only affects the forming quality of corrugated boards but also reduces the working life of a corrugating machine. It also causes a lot of noise. Here,based on a simplified pressure roller mechanism model,its dynamic model was established. Natural frequencies of the pressure roller mechanism were solved using Lagrange equation to provide a theoretical basis for optimization of the mechanism. A vibration test was conduct for the pressure roller mechanism to verify the correctness of its dynamic model. Finally,its natural frequencies were increased to avoid resonance by changing factors to affect natural frequencies of the pressure roller mechanism.
