Description

Technical Field

[0001] The present application relates to the technical field of printing machines, for example, to a top inkjet mechanism of a lifting type digital printing machine. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, ink is applied to the places where the text and image are on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating printed products that are identical to the printing plate. The invention and development of the printing press has played an important role in the spread of human civilization and culture.

[0003] The inkjet device in the current traditional printing machine is generally fixed, that is, the inkjet device does not move, and the inkjet device sprays the paper when the paper conveying mechanism drives the paper to move. However, this fixed inkjet device lacks adjustability, and the staff cannot adjust the distance between the inkjet device and the paper according to actual needs. This cannot improve the inking effect of the paper and the quick and effective reciprocating inkjet spraying on the printed matter; it is also inconvenient for the staff to repair and maintain the inkjet device.
