Printing machine with flexographic printing head

Abstract

The invention relates to the technical field of printing machines, in particular to a printing machine with a flexographic printing head. The printing machine comprises a base plate, support legs andan ink trough, wherein a plurality of first support plates are arranged at the top of the base plate; a fixing rod is in threaded fit with one side of each first support plate; and an impression cylinder, an ink transfer roller, a plate cylinder and an ink fountain roller are respectively arranged between the first support plates. During use, the fixing rod is in threaded fit with the first support plates and the base plate, so that the first support plates are fixed to the base plate, rapid mounting of the printing machine with the flexographic printing head is completed, the first support plates are separated from the base plate by unscrewing the fixing rods, and rapid dismounting of the printing machine with the flexographic printing head is completed; and the rapid mounting and dismounting function is beneficial to improving the later maintenance efficiency of the printing machine with the flexographic printing head, reducing the maintenance difficulty, reducing the maintenance cost and improving the maintenance effect.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a printing machine with a flexographic printing head. Background technique [0002] The printing plate of the printing machine with a flexographic printing head has a certain degree of flexibility, the graphic part is raised, and the non-graphic part is concave. When printing, the ink feed roller (rubber roller) in the ink tank first transfers the stained ink to the printing plate cylinder (anilox metal roller), and then the excess ink on the surface of the anilox printing plate cylinder is removed by the ink feed roller. Then the ink is evenly and stably applied to the surface of the ink transfer roller by the printing plate cylinder. When the printing material (such as a plastic film) passes between the ink transfer roller and the impression cylinder, the graphic on the printing plate will Transfer to substrates for clear graphics. [0003] However, the existing pri...

Problems solved by technology

[0003] However, the existing printing machine with flexographic printing head cannot adjust the height, which is not conducive to connecting with various processing machinery to form an assembly line, which reduces the compatibility of the device and narrows the application range of the device. Printing machines with flexographic printing heads cannot realize quick installation and disassembly functions, which is not conducive to improving the post-maintenance efficiency of printing machines with flexographic printing heads, and increases the maintenance cost of printing machines with flexographic printing heads. It is inconvenient to add ink to the printing machine of the printing head, resulting in ink splashing. When the ink deteriorates or impurities need to be replaced, it is difficult to clean the ink tank and replace the ink, which reduces the service life of the printing machine with flexographic printing head.
