| 目的 预测凹版印刷刮墨刀最佳安装位置和使用要求。方法 应用分析软件，分别建立油墨流体模型和刮墨刀固体模型，并进行液固耦合分析。结果 刮墨刀在油墨冲击影响下，随着安装角度的增加，其刀锋处产生的位移变化率明显下降；随着刮墨刀厚度的增加，刀锋处位移逐渐减少。验证出在软包装印刷过程中，刮刀的最佳安装角度为55°~65°，易选用厚度为0.15 mm刮墨刀，在伸长量为5～6 mm时，才能使刮刀处于最佳刮墨状态。结论 文中的研究为合理地选用和设计刮墨刀提供了参考，同时采用液固耦合分析凹版印刷过程的方法，对量化分析印刷过程具有一定的实际和理论意义。 |

| The work aims to predict the optimal installation and usage requirements of gravure scraper. Liquid-solid coupling analysis was carried out by respectively establishing ink fluid model and scraper solid model with the analysis software. Under the influence of ink impact, with the increase of installation angle, the displacement change rate of the blade was obviously decreased, and the blade displacement gradually decreased with the increase of the scraper thickness. It was verified that, in the printing process of the flexible package, the optimal installation angle of the scraper was 55°~65°, and the 0.15 mm thick scraper was easily selected. When the elongation was 5~6 mm, the scraper could be in the best scraping state. The proposed study provides a reference for the rational selection and design of the scraper; at the same time, the method of liquid-solid coupling analysis of the gravure printing process has some practical and theoretical significance for the quantitative analysis of printing process. |
