| 摘 要： | 现有凹印机干燥装置喷风嘴出风速度达不到要求,导致印品干燥不充分,同时降低了印刷速度.实际上,干燥效率低已经成为制约凹印机速度的主要因素.通过流体动力学的计算来模拟热风在风嘴内的流动状态,从结构设计上找出影响热风速度的主要因素,为干燥装置的优化改进提供理论依据,解决设计生产过程中的盲目性.通过对现有的喷风嘴结构的数值模拟...

| Abstract: | With existing drying device in gravure press,the air velocity of the air nozzles can not meet the processing requirement,which leads to get insufficient drying and lower the printing speed.In fact,the drying efficiency has become a key factor in restricting the printing speed of gravure printing.The paper simulated the fluid state of heat air inner the air nozzles through calculation fluid dynamics,and from construction designs,found out the main factors,which influence the heat-air speed,thus provided the ... |
