Background

An offset printing press is a kind of offset printing press, in which printing images are first printed on a blanket cylinder from a printing plate and then transferred to paper by the blanket cylinder. Offset presses can be divided into sheet-fed offset presses and web-fed offset presses according to different paper feeding modes, and can be divided into single-color, double-color, four-color and multi-color presses according to the number of printing colors finished by one paper feeding, small offset presses, six-opening, four-opening, split-opening and full-paper presses according to the maximum paper breadth to be printed, and double-sided presses capable of finishing two-sided printing simultaneously by one paper feeding. The sheet-fed offset press is a lithographic printing press, is used for printing high-grade commercial printed matters and packaging printed matters, and is the mainstream of modern paper printing. When the offset press is used, the ink body is not thick enough due to the high rotating speed, so that the ink is split between ink rollers of the press, ink particles are splashed from running equipment by centrifugal force, and the particles scatter in a mist shape and are distributed in the air of a printing workshop to form an ink scattering phenomenon. The offset printing ink also contains a certain amount of volatile organic compounds, benzene series, ozone and the like can be generated in the curing and drying process, the waste gas is harmful to a human body and needs to be recovered through an ink absorption and exhaust device of the offset printing machine, however, the ink absorption and exhaust device of the general offset printing machine is unreasonable in structure arrangement, ink drops are shielded by the rotation of the lower part, waste liquid on the inner wall of the air suction pipe can still drip onto the offset printing machine in the rotating process, meanwhile, the adsorption device in the air suction pipe is difficult to replace, and the working efficiency is reduced.
