Description

Technical Field

[0001] The utility model relates to a printing press, in particular to a multi-color synchronous printing ink transfer mechanism of a flexographic printing press. Background Art

[0002] Flexographic printing press is a common printing equipment. Its working principle is that the ink in the ink cartridge is transferred to the anilox roller through the ink transfer roller, and then the ink is transferred to the plate roller through the anilox roller. The plate roller and the pressure roller cooperate to print on the substrate. In actual printing processing, sometimes it is necessary to print patterns of different colors at different positions of the substrate. At this time, the substrate needs to be pulled to different flexographic printing units for printing. This results in a large number of printing units required for the equipment, a complicated structure, and multiple printings are required. The printing efficiency is not high, and the user experience is not good. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the utility model is to provide a multi-color synchronous printing ink transfer mechanism of a flexographic printing machine for solving the above-mentioned problem.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] The multi-color synchronous printing ink transfer mechanism of a flexographic printing machine is characterized in that it includes an ink cartridge, a partition is arranged in the ink cartridge, the partition divides the ink cartridge into at least two ink storage chambers that are not connected to each other, the anilox roller is provided with ink transfer anilox patterns corresponding to each ink storage chamber, and interval sections are arranged between each ink transfer anilox patterns so that each ink transfer anilox pattern is not connected to each other.

[0006] An ink transfer roller is arranged corresponding to each ink storage cavity. The ink transfer roller is arranged in the corresponding ink storage cavity. The ink transfer roller and the ink transfer patterns on the anilox roller correspond to each other one by one to transfer ink.

[0007] Each ink transfer roller is connected to a drive shaft.

[0008] A scraper frame is provided corresponding to the anilox roller, and ink scrapers corresponding to the ink transfer anilox patterns are arranged on the scraper frame.

[0009] The multi-color synchronous printing ink transfer mechanism of the flexographic printing machine of the above technical solution can divide the ink cartridge into a plurality of unconnected ink storage chambers, and can load inks of different colors into corresponding ink storage chambers respectively, and then transfer the inks of different colors to the corresponding ink transfer anilox patterns on the anilox roller through corresponding ink transfer rollers and then transfer them to the plate roller for printing, thereby realizing synchronous printing of different colors at different positions of the substrate in a single printing process, effectively reducing the printing units and improving printing efficiency.

[0013] As shown in the figure, the multi-color synchronous printing ink transfer mechanism of the flexographic printing machine disclosed in the utility model includes an ink cartridge 8, a partition 7 is arranged in the ink cartridge 8, and the partition 7 divides the ink cartridge 8 into at least two ink storage chambers 5 that are not connected to each other. The anilox roller 4 is provided with ink transfer anilox patterns 3 corresponding to each ink storage chamber 5, and a spacing section 2 is arranged between each ink transfer anilox pattern 3, so that each ink transfer anilox pattern 3 is not connected to each other, ensuring that the ink on different ink transfer anilox patterns 3 will not be mixed. Further, an ink transfer roller 6 is arranged corresponding to each ink storage chamber 5, and the ink transfer roller 6 is partially arranged in the corresponding ink storage chamber 5. The ink transfer roller 6 corresponds to the ink transfer anilox pattern 3 on the anilox roller 4 one by one to cooperate in ink transfer, and each ink transfer roller 6 is connected to the drive shaft 9. By controlling the rotation of the drive shaft 9, all the ink transfer rollers 6 can be driven to rotate synchronously. A scraper holder 11 is provided corresponding to the anilox roller 4 , and ink scrapers 10 corresponding to the ink transfer anilox patterns 3 are arranged on the scraper holder 11 , which can cooperate with the anilox roller 4 to scrape ink and ensure that no color bleeding occurs on each ink transfer anilox pattern 3 .

[0014] The working principle of the utility model is: by controlling the rotation of the ink transfer roller 6, the inks of different colors in the corresponding ink storage chambers 5 in the ink cartridge 8 can be respectively transferred to the corresponding ink transfer anilox patterns 3 on the anilox roller 4, and then the inks of different colors are transferred to the corresponding positions of the plate roller 1 through the ink transfer anilox patterns 3, so as to realize multi-color synchronous printing operation, or the anilox roller part is directly arranged in the ink cartridge 8, and the inks of different colors are directly transferred from the different ink storage chambers 5 in the ink cartridge 8 to the corresponding ink transfer anilox patterns 3, and then the inks of different colors are transferred to the corresponding positions of the plate roller 1 through the ink transfer anilox patterns 3.

[0015] The structure of the utility model can divide the ink cartridge into a plurality of unconnected ink storage chambers, so that inks of different colors can be respectively loaded into corresponding ink storage chambers, and then the inks of different colors are transferred to the corresponding ink transfer anilox rollers through corresponding ink transfer rollers and then transferred to the plate roller for printing, so that different positions of the substrate can be printed synchronously in different colors in a single printing process, thereby effectively reducing the printing units and improving the printing efficiency.
