Abstract
Description
Technical Field
[0001] The utility model relates to a printing press, in particular to an anilox roller ink supply mechanism for a flexographic printing press. Background Art
[0002] Flexographic printing press is a common printing equipment. The working principle of traditional flexographic printing press is to transfer ink to the anilox roller through the ink transfer roller set in the ink cartridge, and then transfer the ink to the plate roller through the anilox roller, and finally the plate roller and the pressure roller cooperate to print the substrate passing through. In actual use, in order to ensure that the ink transfer roller can transfer ink to the anilox roller, the position of the ink transfer roller and the anilox roller needs to be adjusted during installation, and the adjustment operation is relatively troublesome. The ink transfer quality of this ink transfer method is not high, and after the ink is transferred to the anilox roller, it is necessary to wait for the anilox roller to rotate a certain angle to the ink scraper to scrape off the excess ink. In this process before scraping, the excess ink on the anilox roller may flow freely, affecting the subsequent ink transfer operation; in addition, the traditional single ink transfer roller and anilox roller cooperate with the ink transfer structure, which can only realize a single monochrome printing operation. When it is necessary to print different colors at different positions of the printing substrate, it is necessary to set up multiple printing mechanisms for multi-color printing, resulting in low printing efficiency. 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 an ink supply mechanism for an anilox roller 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 inking mechanism of the anilox roller of a flexographic printing machine comprises an anilox roller, and is characterized in that: a scraper seat is arranged corresponding to the anilox roller, an upper scraper and a lower scraper are arranged on the scraper seat, a plurality of ink supply holes are arranged on the scraper seat, and sealing blocks are arranged on both sides of each ink supply hole correspondingly, the upper scraper, the lower scraper, the anilox roller and the sealing blocks surround an ink cavity corresponding to the ink supply holes one by one, each ink supply hole is connected to a corresponding ink supply tube, and each ink supply tube is connected to a corresponding ink barrel through a corresponding pump body.
[0006] The ink supply hole is aligned with the upper ink scraper or the lower ink scraper.
[0007] The sealing block is made of rubber.
[0008] An ink receiving box is arranged below the anilox roller.
[0009] The anilox roller is provided with ink transfer patterns corresponding to the respective ink cavities, and there are separation sections between adjacent ink transfer patterns so that the adjacent ink transfer patterns are not connected to each other.
[0010] In the anilox roller inking mechanism of the flexographic printing machine of the above technical solution, the pump body presses the ink in the ink barrel into the ink cavity corresponding to the ink supply hole enclosed by the upper scraper, the lower scraper, the anilox roller and the sealing block through the ink supply tube, so that the ink in the ink cavity can directly contact the anilox roller to transfer the ink, thereby ensuring the ink transfer quality, and the anilox roller can immediately scrape the ink through the corresponding scraper after the inking is completed, so that the ink scraping is more timely, and the excess ink is prevented from flowing freely on the anilox roller, thereby ensuring the subsequent ink transfer quality; in addition, since the various ink cavities are not connected to each other, different colors of ink can be selected to pass into the corresponding ink cavity, thereby realizing a single multi-color ink transfer, and then realizing subsequent single-color and multi-color printing operations, effectively improving printing efficiency.

[0015] As shown in the figure, the anilox roller ink supply mechanism of the flexographic printing machine disclosed in the utility model comprises an anilox roller 1, a scraper seat 5 is provided corresponding to the anilox roller 1, an upper scraper 8 and a lower scraper 9 are provided on the scraper seat 5, a plurality of ink supply holes 10 are provided on the scraper seat 5, and a sealing block 7 is provided on both sides of each ink supply hole 10 of the scraper seat 5. In this embodiment, the sealing block 7 is made of rubber. The upper scraper 8, the lower scraper 9, the anilox roller 1 and the sealing block 7 enclose an ink cavity corresponding to the ink supply hole 10 one by one, each ink supply hole 10 is connected to a corresponding ink delivery tube 6, and each ink delivery tube 6 is connected to a corresponding ink barrel through a corresponding pump body. Further, the ink supply hole 10 is aligned with the upper scraper 8 or the lower scraper 9, so that the ink flowing into the ink cavity can flow along the scraper to the anilox roller 1, thereby improving the ink transfer quality. An ink receiving box 4 is provided below the anilox roller 1 to catch the dripping excess ink. The anilox roller 1 is provided with ink transfer patterns 2 corresponding to each ink cavity, and there are separation sections 3 between adjacent ink transfer patterns 2, so that adjacent ink transfer patterns 2 are not connected to each other, thereby avoiding the occurrence of color bleeding of inks of different colors when multi-color ink transfer is performed.
[0016] In the structure of the utility model, the pump body presses the ink in the ink barrel through the ink delivery tube 6 into the ink cavity surrounded by the upper scraper 8, the lower scraper 9, the anilox roller 1 and the sealing block 7 corresponding to the ink supply hole, so that the ink in the ink cavity can directly contact the anilox roller 1 to transfer the ink, thereby ensuring the transfer quality of the ink, and the anilox roller 1 can immediately scrape the ink through the corresponding scraper after the inking is completed, so that the scraping is more timely, and the excess ink is prevented from flowing freely on the anilox roller, thereby ensuring the subsequent ink transfer quality; in addition, since the various ink cavities are not connected to each other, different colors of ink can be selected to pass into the corresponding ink cavity, thereby realizing a single multi-color ink transfer, and then realizing subsequent single-color and multi-color printing operations, effectively improving printing efficiency.
