The Research and Analysis of Heating Method of Laminating Machine Based on Finite Element

摘要: 覆膜机是通过在承印材料上压上一层薄膜来提高产品的美观及保护效果的印后设备。加热系统是覆膜设备重要的功能单元之一，选择合适的温度及系统的补温性能对覆膜效果影响很大。目前，市场上覆膜机加热方式多种多样，其中最常用的方式之一为导热油循环系统，但流体性质容易变化，导致加热效果不稳定，结果很难预测。提出了热力学分析及计算方法，通过有限元分析，建立不同温度下导热油加热系统的模型，通过分析求解，得到热辊表面的温度变化规律曲线，提出了一种新型的加热方式，并对其做了相应的热力学分析。

Abstract: Laminating machine is a kind of post-print equipment that presses a thin film on printing materials to improve the aesthetic and protective effect of product. The heating system is one of the important functional units of laminating machine. It has a great effect on laminating effect to select the appropriate temperature and the complement temperature performance of the system. Currently, there is a variety of heating methods of laminating machine in the market, the most common one of which is conducting oil circulation system, but the fluid properties easily change; that leads to the instability heating effects, therefore, it’s difficult to predict the results. This paper establishes the different temperature model of oil heating system, analyses and solves the surface temperature variation of heating cylinder by the finite element. In addition, it also proposes a new type of heating method, and then it makes the corresponding thermodynamic analysis.
