Abstract

The invention relates to a printer printing quality detection device which comprises four sets of quality detection devices arranged in a four-color printer. The quality detection devices and printing rollers of the four-color printer are arranged at intervals, and the quality detection devices correspond to the printing rollers one to one and are located on the rear sides of the corresponding printing rollers. Each quality detection device comprises a conveying platform and a detection unit, wherein the detection unit is located above the conveying platform, and the conveying platform is provided with a positioning material blocking structure and a conveying mechanism. The positioning material blocking mechanism comprises a driving air cylinder, wherein the end of a piston rod of the driving air cylinder is fixedly connected with an intercepting rod. The quality inspection devices are arranged behind all the printing rollers, the printing quality of each printing roller is detected, and if the printing quality goes wrong, a worker can rapidly repair and adjust the failing printing rollers and related printing mechanisms, and the effect of monitoring the working state of the printing equipment is improved.

Description

technical field [0001] The present application relates to the field of quality detection of printed matter, in particular to a printing quality detection device for a printing machine. Background technique [0002] At present, in the production of paper printing such as book printing, four-color printing machines are usually used. Four-color printing machines refer to four inks of different colors, such as three primary colors (yellow, magenta, cyan) and black by subtractive color printing. , a printing press that realizes the lithographic method of graphic reproduction. When the printing machine is printing, the paper sheets are sequentially transported through the printing rollers with inks of different colors, and the paper sheets are printed in different colors sequentially. In the actual printing process of the printing roller, due to the difference in the temperature and humidity of the printing paper, ink and printing machine working environment used in printing, the...
