What are the printing equipment?

Printing machines are divided into relief, lithography, intaglio and screen printing machines according to printing plate forms; According to the form of paper used, it is divided into sheet-fed printing machine, web printing machine and so on. The printing structure of printing machine can be divided into flat press, circular press, stop rotation, first rotation, second rotation, reciprocating rotation, circular press and so on. Printing equipment is mainly composed of paper feeding device, printing device and paper receiving device. In addition to printing machinery, it also includes binding machine, carbonless carbon paper bill printing machine, automatic die cutting machine, high-speed box pasting machine and so on. At the same time, it is necessary to add operation rooms such as distribution room, laser knife mold room and binding and pasting table workshop. These printing production conditions are all the production conditions that regular printing production enterprises should have. Screen printing of flat screen curved surface refers to screen printing with flat screen on cylindrical or conical curved surface. Under certain conditions, curved surfaces such as ellipse, drum surface and cambered surface can also be printed by screen printing. Dry screen curved surface screen printing machine is a machine that prints the above curved surface with flat screen. When printing, the flat screen printing plate moves with the substrate, while the squeegee is stationary. The flat screen printing plate is clamped on the screen frame and moved at a constant speed by the flat screen curved screen printing machine. Due to the friction of the mesh plate, the substrate placed on the supporting device rotates accordingly. The linear speed of curved substrate at the nip is consistent with the moving speed of flat screen printing plate, thus realizing ink scraping printing. With the continuous development of the domestic economic situation, many industries have also made progress and development. Printing industry has developed rapidly in recent years. Due to the increasing demand for various printing products in recent years, the number of domestic printing production enterprises is also increasing. Many printing enterprises can produce various printing products according to users' requirements. For any formal enterprise, some printing production equipment is essential, which can effectively maintain the printing enterprise. Among these necessary printing equipment, printing machine is the most important type of printing production machinery. Printing machine is a mechanical device that presses the inking surface on the surface of media (such as paper and cloth) to image. It was first invented by German Gutenberg in 1440. Modern printing machines are generally composed of loading plates, inking, stamping and paper feeding (including folding). How it works.
