Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to an automatic ink adding device for printing machines. Background Art

[0002] A printing press is a machine used to print text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, 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 mounted on a printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by a printing press. Then, the ink is directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating a printed product 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 ink in the ink basin of a printing press is consumed too quickly during large-scale printing, and ink needs to be added frequently. However, most existing printing presses are troublesome to add ink, and ink is usually added to the ink basin manually. This method is cumbersome and inefficient, greatly reducing the printing speed. In addition, human errors may occur sometimes, resulting in inaccurate amount of ink added, thus affecting the printing quality. Utility Model Content
