目前,在印刷业中,对于一些较高级的印刷品,如商标、广告等的要求越来越高,它们的绝大部分都用上了烫印技术。有的为了提高工效,降低生产成本,提高电化铝的利用率,又用上了烫印跳步技术。而跳步技术,到去年为止,仍是采用上海青工厂生产的电子数控跳步器,它在技术上较先进,但造价昂贵,也不便于修理。为此,我们设计并试制成功了一种结构简单,使用方便,封闭性好,造价便宜的跳步机构——FTB型机械式跳步器。它的结构如图所示,主要由齿条、小齿轮、棘轮、
At present, in the printing industry, for some higher-level printed materials, such as trademarks, advertisements and other requirements are getting higher and higher, most of them are using hot stamping technology. Some in order to improve ergonomics, reduce production costs, improve the utilization of aluminum, but also with the stamping step-by-step technology. The jumping technology, until last year, is still using the Shanghai Green Factory production of electronic CNC stepper, which technologically more advanced, but expensive, it is not easy to repair. To this end, we design and trial success of a structure is simple, easy to use, closed and cheap jumping mechanism - FTB mechanical steppers. Its structure as shown, mainly by the rack, pinion, ratchet,
