Multicolor printing machine and method for multicolor printing

Abstract

The invention relates to a multicolor printing machine and a method for multicolor printing. The multicolor printing machine comprises a feeding-receiving station, a plurality of printing stations with the same number of printing colors, a plurality of drying stations with the same number of the printing colors, and a delivery mechanism of printing materials, wherein printing machine sets on the plurality of the printing stations and drying machine sets on the plurality of the drying stations are arranged in an inverted sequence according to a color printing sequence, every station is arranged to form a circulation at equal interval with one another, and the delivery mechanism delivers the printing materials to perform conversion according to a hop count of printing color number subtracting one among the stations. The multicolor printing machine and the method for multicolor printing arrange the stations intensively with compact structures, shorten the space length for an operator to perform route detections, reduce the fatigue consumption for the operator, and are advantageous for discovering printing quality faults in time.

Description

technical field [0001] The invention relates to a printing mechanism, more specifically, to a multi-color printing machine and a multi-color printing method thereof. Background technique [0002] With the continuous development of multi-color overprinting technology, multi-color printing machines with multiple printing units continue to appear. Generally, multiple stations of an existing multi-color printing machine are arranged linearly, and a drying box needs to be installed after each color printing unit, and the printed substrate of the previous color can be dried before being transferred to the next color printing unit. Therefore, in the case of multi-color overprinting, the printing machine with linear arrangement of stations is very long and takes up a lot of space. For example, for a linearly arranged five-color printing machine, it is necessary to set up a discharge station, a first-color printing station, a first-color drying station, a second-color printing stati...

AI Technical Summary

Problems solved by technology

For example, for a linearly arranged five-color printing machine, it is necessary to set up a discharge station, a first-color printing station, a first-color drying station, a second-color printing station, a second-color drying station, and a third-color printing station. Station, third-color drying station, fourth-color printing station, fourth-color drying station, fifth-color printing station, fifth-color drying station, receiving station, a total of 12 stations bit, so the production line will be very long

Moreover, the distance for the operator to patrol and check the printing station is also very long, and the printing quality failure cannot be found in time, and the labor intensity of the operator is very high.
