Abstract

The invention relates to a paperboard preprinting production line. The paperboard preprinting production line comprises an unwinding device, a tension device, a plurality of printing devices and a winding device which are arranged in sequence, wherein each printing device comprises a rack, an ink cartridge and an ink rotating roller, the ink cartridge is fixedly arranged on the side, away from theunwinding device, of the rack, the ink rotating roller is horizontally and rotationally arranged on the rack, a mounting seat is arranged on one side of the rack in a sliding manner in the vertical direction, a mounting rod is fixedly arranged on the mounting seat, a mounting block is rotationally arranged on the mounting rod, a mounting plate is arranged on the top wall of the mounting block ina sliding manner, and a scraper parallel to the ink rotating roller is arranged on the edge, close to the ink rotating roller, of the mounting plate. When an operator starts the ink rotating rollers to convey ink, thickness of the ink on the ink rotating rollers is adjusted by adjusting the distance between the scrapers and the corresponding ink rotating rollers, resistance to the scrapers when the scrapers scrape the ink on the corresponding ink rotating rollers is adjusted by adjusting angles between the scrapers and the corresponding ink rotating rollers, so that vibration on the scrapers and the ink rotating rollers is reduced, and the paperboard preprinting production line has the effect of improving distribution uniformly of the ink on the ink rotating rollers.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a cardboard pre-printing production line. Background technique [0002] The traditional gravure printing machine is ink-immersion gravure printing, which is a direct printing method. First, a gravure printing roller is made, and a concave mesh is made on the gravure printing roller. It will be filled with ink, and then under pressure, the gravure printing roller and the substrate cylinder will roll against each other, and the ink contained in the concave cells on the gravure can be directly imprinted on the substrate. The size and depth of the pits are determined. [0003] The patent with the authorized notification number CN107585621B discloses a fully automatic assembly line for suture workbooks, including an inner page conveying device, a cover conveying device and a bonding device; the inner page conveying device is sequentially provided with an unwinding device, ...
