Abstract

The invention discloses a water and ink co-feeding device of a commercial printing machine. The water and ink co-feeding device comprises a rubber roller, a plate cylinder, an ink vibrator and a dampening vibrator which are bridged between wallboards at the two sides of the printing machine; the water and ink co-feeding device further comprises an inking roller matched with the ink vibrator, an inking roller and ink vibrator pressure adjusting mechanism, an inking roller and plate cylinder clutch mechanism, an inking roller and plate cylinder pressure adjusting mechanism, a form dampening roller matched with the dampening vibrator, a form dampening roller and dampening vibrator pressure adjusting mechanism, a form dampening roller and plate cylinder clutch mechanism, a form dampening roller and plate cylinder pressure adjusting mechanism, a water and ink co-feeding roller, a water and ink co-feeding roller and inking roller pressure adjusting mechanism and a water and ink co-feeding roller and form dampening roller pressure adjusting mechanism; and the water and ink co-feeding roller is arranged between the form dampening roller and the inking roller and is simultaneously engaged and disengaged with the inking roller and the form dampening roller through the water and ink co-feeding roller clutch mechanism. According to the water and ink co-feeding device, the printing color can be brighter, and the quality of a finished product printed on paper with poor water absorption is greatly improved.

Description

technical field [0001] The invention relates to an ink and water co-laying device for a commercial printing machine. Background technique [0002] At present, printing is realized on a conventional rotary offset printing machine, and water (fountain solution) and ink (ink) are supplied to the printing plate respectively. In this printing method, water is supplied first, and the water is transferred from the stringer roller 500 to the dampening roller 600. , and then transferred from the water roller 600 to the printing plate cylinder 200, forming a layer of water film on the printing plate; then ink is supplied, and the ink is transferred from the inking roller 300 to the ink forming roller 400, and then from the ink forming roller 400 to the printing plate On the cylinder 200; the ink mixes with water on the printing plate and adheres to the pattern of the printing plate, and finally passes to the rubber cylinder 100 to complete the printing (see figure 1 ). The main disa...
