| 目的 解决平压平烫印机大面积烫印铝箔与承印品粘连问题。方法 通过对烫印过程中铝箔与印刷品产生粘连的原因进行分析， 结合生产实际， 提出大版面烫印过程应注意的问题。结果 采用同向揭纸方式， 有0.5 kg/mm2的力作用在电化铝箔与承印品之间， 易于分离； 增加风力， 采用直径约为1~2 mm小孔吹风管设计； 采用改进正弦变速运动方式进行伺服跟踪控制； 选用大版面烫印专用电化铝箔， 以利于分离铝箔与承印品。结论 从揭纸方式、 吹风系统、 伺服系统和电化铝箔材料选择等4个方面来改进设计方案与烫印工艺， 并控制好烫印过程中的速度、 温度、 压力等各相关因素， 即可获得理想烫印效果。 |

| Objective To solve the conglutination problem between the hot stamping foil and the prints found with the platen press foil stamping machine. Methods The problems in the layout of stamping process were brought up, by analysis of the conglutination problem between the aluminum foil and the prints during the stamping process, in combination with the actual production. Results By the way of unidirection paper uncovering method, there was 0.5 kg/mm2 force acting between the aluminum foil and the printing products, which facilitate easy separation. Wind power was increased using a small-hole blowing tube design with a diameter of about 1~2 mm. The improved sinusoidal variable motion was used for servo tracking control. In order to facilitate the separation of the aluminum foil and the prints , the large-layout printing specific aluminum foil was used. Conclusion Ideal printing results were obtained by improving the design scheme and technology of the hot stamping process from the four aspects of paper uncovering manner, blowing system, servo system and selection of aluminum foil material, and by controlling the related factors in the printing process including velocity, temperature and pressure. |
