Въведение на фона на сгъваемата машина

В средата -50 s от миналия век, в движението на технологичните иновации, някои печатници произвеждат сгъваеми машини, създавайки прецедент за изгода на производствените сгъваеми машини . през февруари 1968 г., Държавната комисия за планиране и Първата министерство на машините и други звена, които са взели съвместно, за да се сдобият с "председател на Мао". Xinshao Printing Machinery Factory (the predecessor of Hunan Xinshao Printing Machinery Co., Ltd.) to specialize in the production of folding machines. Until the mid-80s, the ZYl01, ZYl02 full sheet and ZY201 folio knife folding machines were the leading products of folding machines. In order to solve the contradiction of unbalanced printing and installation, the national "Seventh Five-Year Plan" decided that Hunan Xinshao Printing Machinery Factory would introduce foreign advanced folding machine prototypes and technologies to independently develop high-speed folding machines. In the mid-to-late 80s, the factory successively developed ZYH660 hybrid high-speed folding machine and ZYH490 electric knife high-speed folding machine. After the 90s, it was the golden age of the development of folding machines in China. Several manufacturers such as Shanghai Beirenshun Printing Machinery Co., Ltd. have also joined the research and manufacturing редици на сгъваеми машини .

The domestic high-speed folding machine is mainly composed of paper separation system, paper feeding system, bending parallel folding system, vertical folding knife folding system, frame, transmission system, electrical control system and receiving system. Although our ancestors invented printing a long time ago, but today's China's printing technology level is relatively backward, and the domestic advanced folding machine has only reached the international advanced level in the 90s of the Миналия век .

At present, there is a development trend of multi-variety, small batch and short delivery time of printing enterprise orders. This trend will make the start-up preparation time and the frequent set-up time of the machine more and more in the proportion of total production time occupied, while the actual production time is relatively reduced, in the fierce market competition, which means that the finishing company must produce more products in a shorter time in order to get more Печалба . В резултат на това оптимизирането на производствените процеси и интегрирането на оперативните процедури за производство на всеки продукт по -надеждно поставят по -нови и по -високи изисквания на производителите на постпресивно оборудване .
