| 目的 研究网纹辊向印版进行油墨转移的特性。方法 将网纹辊结构简化为轴对称的梯形槽， 使用有限元法对网纹辊油墨转移过程进行数值模拟， 即模拟油墨从网纹辊向印版进行转移， 并且加入网纹辊和印版滚筒的运动情况， 研究了接触角、 梯形槽高宽比和角速度对油墨转移的影响。结果 分析了油墨从网纹辊转移到印版的影响因素， 油墨转移率随着上板接触角的增加而减小， 随着梯形槽接触角的增大而增大， 梯形槽高宽比越小和角速度越大， 油墨转移率越高。结论 通过对柔印网纹辊油墨转移情况进行数值模拟， 得到了接触角、 梯形槽高宽比及角速度对油墨转移情况的影响规律， 为柔印生产实践提供了理论参考。 |

| The aim of this work was to study the transfer properties of ink between the anilox roller and the plate during printing. The structure of the anilox roller was simplified into an axisymmetric trapezoidal groove, and the ink transfer process was numerically simulated using the finite element method, to simulate the ink transfer from the anilox roller to the plate. The influences of the contact angle, trapezoidal groove aspect ratio and the angular velocity on the ink transfer were studied considering the movement of the anilox roller and the plate cylinder. The influencing factors on ink transfer from the anilox roller to the plate were analyzed, and it was found that the ink transfer ratio decreased with the increasing upper plate contact angle and increased with the increasing dovetail groove contact angle; while the smaller the aspect ratio and the larger the angular velocity, the higher the ink transfer rate. The influencing rules of the contact angle, the aspect ratio and the angular velocity on the ink transfer were obtained by numerical simulation of the ink transfer in the flexographic printing process, which provided theoretical reference for the flexographic printing production. |
