Problems solved by technology
In addition, because the printing method adopts the flat pressing process, it is necessary to ensure sufficient contact time between the printed product and the hot stamping plate during the hot stamping process, so the hot stamping speed is slow, the processing cycle is long, and the efficiency is low, which makes the application of hot stamping limited. many restrictions
[0003] At present, post-press processes such as glazing and die-cutting can be successfully connected to the printing machine, but there are still many problems in the connection between the bronzing process and the printing machine, such as speed mismatch, inaccurate registration, unstable web force, There is no such technology at home and abroad to realize the post-press processing procedures such as hot stamping, embossing, die-cutting, etc. and the web gravure printing machine on-line

The invention relates to a one-step forming method for the online hot stamping and concave-convex die cutting of web gravure printing. The one-step forming of the online hot stamping and concave-convex die cutting of a printing machine cannot be realized in the prior art. In the method, a printed web is subjected to hot stamping; the accuracy of the hot stamping is ensured through a line cursor tracker and an encoder; as a series roller is adjusted through an adjusting motor, the sum of the rotating velocity of a charging roller and the jumping velocity of the serial roller equals to the transmission velocity of the web; the temperature of a hot stamping roller is controlled between 200 DEG C and 260 DEG C; the pressure of the hot stamping roller is controlled between 0.3MPa and 0.7MPa; the rotating speed of the hot stamping roller is controlled between 130r / min and 136r / min; an alarming system reminds a user of pre-placing an electroplating aluminum foil; the hot-stamped web passes through a processing device; and therefore, the concave-convex pressing and die cutting are realized, and the online hot stamping and the concave-convex die cutting of the web gravure printing are realized. The one-step forming method has the advantages of simple technology, reduced cost of raw materials and improved accuracy.
Description
technical field [0001] The invention belongs to the field of printing technology, and in particular relates to a one-time forming method of online bronzing concave-convex die-cutting for web gravure printing. Background technique [0002] The continuous emergence of new post-press surface finishing processes with higher and higher technological content makes printed matter more colorful. Improving the surface finishing effect of printed matter is one of the best ways to increase added value. Bronzing is a relatively complicated process that affects There are many factors in the quality of hot stamping, the main factors are web, anodized aluminum, hot stamping plate, hot stamping pressure, temperature and speed, which are directly related to the hot stamping process. In addition, because the printing method adopts the flat pressing process, it is necessary to ensure sufficient contact time between the printed product and the hot stamping plate during the hot stamping process,...
