Multi-paper-path double-face digital printing system and digital rotary press

Abstract

The invention provides a multi-paper-path double-face digital printing system and a digital rotary press. The multi-paper-path double-face digital printing system which integrates a paper path split part, a bearing part, a reversing part and a digital printing head is arranged by fully utilizing the top space of the conventional rotary press, so that single-face digital printing can be performed by randomly selecting all printing plates of a plurality of paper paths of printing of the machine by using one digital printing head. The conventional rotary press can be changed into the digital rotary press by only additionally arranging the device for reconstruction but without purchasing a new digital printing machine, the device has good integrity, strong operability of a reconstruction process is also guaranteed, the mounting cost is low, the nonproductive labor can be effectively saved, and the reconstructed equipment not only has no influence on the original printing function but also can realize non-limited digital printing tasks according to requirements.

Description

technical field [0001] The invention relates to the field of newspaper printing, in particular to a double-sided digital printing system with multiple paper paths and a digital rotary printing machine. Background technique [0002] Today, the global newspaper industry is in a market of social changes, and the rapid development of the Internet, TV and various media all have a huge impact on the development of traditional newspaper publishers. The number of newspaper subscribers is decreasing, it is difficult to attract and retain young readers, and the reduction in circulation has resulted in a decrease in advertising printing profits - all of which make traditional newspaper publishers also face great challenges, how to follow the trend in the changing market and provide good To cope with all these, traditional newspaper publishers are forced to explore, innovate and improve their own existing technologies in order to achieve greater profit growth. [0003] As we all know, ...

AI Technical Summary

Problems solved by technology

However, most of the current digital printing heads are relatively large. For example, the installation of the latest Kodak digital printing head requires a space of 1100mm (height) × 800mm (length), and the existing traditional rotary printing machine structure does not foresee Leave enough space for the installation of digital printing equipment, which makes the application of the latest digital printing device on traditional rotary printing machines subject to many limitations, so digital printing cannot be realized without equipment modification, but how to choose a suitable installation location and be stable The setting of the supporting mechanism is the key and difficult point of the technology, which directly affects the success of the transformation

[0008] However, since one digital printing head can only undertake the printing task of one paper path and one layout, it is the simplest solution to set up a digital printing head corresponding to each paper path, but this will lead to a very high cost of equipment modification, such as supporting three In the case of double-sided simultaneous printing of the paper path, it means that six sets of digital printing heads need to be configured. Regardless of how to find space for the above-mentioned digital printing heads in the traditional rotary machine, in practical applications, it is usually not necessary to digitally print multiple paths at the same time. , so the corresponding setting method will inevitably cause unnecessary waste of investment
