Multifunctional coil laminating press

Abstract

The invention relates to a multifunctional coil laminating press. The press is characterized in that the press comprises unwinding device (1) coil from front to back in order after preheating leveling device (2), horizontal double-sided laminating equipment (3), preamble feeding device (4), offset printing unit (5), after simultaneously feeding device (6), coating unit (7) and the winding device (8). The multifunctional coil laminating press uses coil laminating after printing technology instead of conventional inks, screen printing a variety of technology interoperability printing technology and fully reflect the effect of a variety of printing processes, not only improve the printing results, ensure that the printing synchronous precise transfer sheet, but also reduces the use of printing ink environmental pollution and improve environmental protection energy-saving effect.

Description

technical field [0001] The invention relates to a plate printing machine, in particular to a printing machine capable of realizing precise transmission of wide-width laminated plates and synchronously realizing reliable transmission of plates and films. The invention belongs to the technical field of plate laminating machinery. Background technique [0002] There is a considerable distance between "design works" and "printed products", because single-sheet works are easy to realize. If the design needs to be copied in large quantities for the purpose of wide dissemination, the printing process is particularly important. The process characteristics of different printing types are completely different. Take the existing main printing methods as an example. The ink layer of screen printing is thick and embossed, and the concise color blocks and lines of flexographic printing products have a strong visual impact on people. Different printing types have their own specific print...

Problems solved by technology

Different printing types have their own specific printing requirements. According to different printing carriers, their printing suitability is quite different, and the actual printing effect of the product is also very different.

[0003] The traditional offset printing process has the shortcomings of low printing quality and too many defective products when printing on thinner flexible carriers such as paper and film. The main reason is that the flexible carrier is not easy to position on the printing production line. The longer the printing production line, the more It is prone to the deviation and deformation of the flexible carrier. Moreover, if the method of printing directly on the surface of the flexible material itself is used, it is easy to cause defects in the deformation of the flexible carrier during printing. Under the influence of tension, extension and deformation occur, resulting in low pattern resolution of printed products, and even defects of overlapping patterns. These reasons also restrict the conventional offset printing process from being able to adapt to printing on ultra-thin and wide-format printing carriers.

In order to ensure the printing quality, most of the printing on the surface of the flexible carrier adopts the gravure flexo printing process, but the gravure flexo printing also has limitations. Its main disadvantages are: complex pre-press plate-making technology, long cycle, high cost of plate-making, and inability to adapt to short-runs Lively market environment

However, because the offset printing process cannot be used for film printing, the production cost is high, and it is not suitable for the current market environment with a lot of short-term jobs.
