Printing presses are divided into letterpress, offset, gravure and screen printing presses according to the form of printing plates; they are divided into sheet-fed printing presses, web printing presses etc. according to the form of paper used. According to the printing structure, it is divided into flat flat printing presses, rotary flat printing presses, stop-rotary printing presses, one-rotation printing presses, two-rotation printing presses, reciprocating rotary printing presses, rotary rotary printing presses, etc. Printing equipment mainly consists of paper feeding device, printing device, paper delivery device and other devices. In addition to printing machinery, including perfect binding machines, carbonless copy receipt printing machines, automatic die-cutting machines, high-speed folder gluers, etc., it is also necessary to add additional operation rooms such as a film hair room, a laser cutting room, and a binding and pasting workshop. These printing production conditions are the production conditions that regular printing production enterprises should have. Flat screen curved surface screen printing refers to screen printing with a flat screen on a cylindrical or conical curved surface. Under certain conditions, screen printing can also be performed on curved surfaces such as elliptical surfaces, drum-shaped surfaces, and arc surfaces. The dry mesh curved screen printing machine is a machine that uses a flat screen to print on the above-mentioned curved surfaces. When printing, the flat screen printing plate and substrate move, while the squeegee remains stationary. The flat screen printing plate is clamped on the screen frame and driven by the flat screen curved screen printing machine to move at a constant speed. Due to the friction of the screen plate, the substrate placed on the supporting device rotates accordingly. At the printing line, the linear speed of the curved substrate is consistent with the moving speed of the flat screen printing plate, achieving squeegee printing. With the continuous development of the domestic economic situation, many industries have also made progress and development. The printing industry is an industry that has developed rapidly in recent years. Due to the increasing demand for various printing products in recent years, domestic The number of printing production companies is also growing. Many printing production companies can produce various printing products according to user requirements. For any formal enterprise, some printing production equipment is essential. These Printing equipment is necessary equipment that can effectively maintain the normal production of printing companies. Among these necessary printing equipment, the printing press is the most important type of printing production machine. A printing press is a mechanical device that presses an inked surface against a media surface (such as paper or fabric) to create an image. It was first invented by the German Gutenberg in 1440. Modern printing presses generally consist of mechanisms such as plate loading, ink coating, imprinting, and paper feeding (including folding). It works original.
