Description

Technical Field

[0001] The utility model relates to the field of printing engineering, in particular to a high-efficiency multi-color printing device for cartons. Background Art

[0002] A high-efficiency multi-color printing device for carton is a device specially used for multi-color printing on the surface of carton. It has the characteristics of high efficiency, high quality, strong flexibility and high degree of automation, and can meet the needs of modern packaging industry for carton printing. It is usually composed of a printing unit, an ink supply system, a conveying system, a drying system and a control system. The printing unit usually includes multiple printing rollers, which print different colors of ink on the surface of the carton in sequence to achieve a multi-color printing effect. The material and surface treatment of the printing rollers will affect the printing quality and durability; the ink supply system is responsible for supplying ink to the printing unit, and generally includes ink cartridges, ink pumps, ink tubes and other components. The ink supply system needs to ensure uniform supply and stable flow of ink to ensure consistent printing quality. The conveying system transfers cartons from one printing unit to the next, and outputs the printed cartons. The conveying system usually adopts belt conveyor, chain conveyor or roller conveyor to ensure smooth conveying and accurate positioning of cartons. After printing is completed, the ink needs to be dried to prevent ink adhesion and blurring. The drying system can adopt hot air drying, infrared drying or ultraviolet drying. The appropriate drying method is selected according to the characteristics of the ink and the printing speed. Control system: controls and coordinates the entire printing device.

[0003] An existing high-efficiency multi-color printing device for cartons is prone to deviation during the carton printing process because the cardboard is not stably fixed. This will cause different color patterns to be unable to be accurately overprinted together, resulting in color deviation, blurring and other problems, seriously affecting the appearance quality of the printed product. It will also cause problems during printing, requiring printing to be stopped and the angle of the cardboard to be adjusted, greatly reducing production efficiency.
