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

Abstract

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.
