Problems solved by technology

[0002] In the scraping structure of the existing mimeograph equipment, the main scraper is set close to the upper end of the roller, and the distance from the ink liquid level is higher. Excessive ink picked up by the roller from the ink tray will scrape off the roller at the main scraper and accumulate drops. Falling back into the ink tray, this makes the ink liquid level unstable and fluctuates, and the ink attached to the position just turned out of the ink liquid surface on the roller will be stained again and flow back into the ink tray, resulting in incomplete ink staining of the roller , the printed pattern or text is incomplete

Embodiment Construction

[0013] The present invention as Figure 1-2 As shown, it includes an ink tray 1, a roller 2 and a scraper 3. The ink tray is used to hold ink, and the lower part of the roller is immersed in the ink of the ink tray. The scraper is arranged on the ink tray and located at one side of the roller;

[0014] Also includes a heater 4, a controller, an imaging mechanism 5 and an inkjet mechanism 6,

[0015] The two ends of the heater 4 are fixed on the side wall of the ink tray and are positioned under the scraper. When the scraper scrapes off the protruding ink, the protruding ink will fall onto the heater to act as a buffer so that the ink level smooth;

[0016] The imaging mechanism is arranged above the doctor blade and is used for the imaging of the roller, the imaging mechanism 5 is connected to a controller, and the controller controls the inkjet mechanism 6, and the inkjet mechanism is located above the imaging mechanism, including a slide Rail 61 and the inkjet box 62 that...

Abstract

The invention provides an ink scraping device which is simple in structure, convenient to operate and capable of improving the ink scraping reliability. The ink scraping device comprises an ink disc, a roller wheel and a scraping knife. The ink disc is used for containing ink. The lower portion of the roller wheel is soaked in the ink in the ink disc. The scraping knife is arranged on the ink disc and located on one side of the roller wheel. The ink scraping device further comprises a heater, a controller, an imaging mechanism and an ink jet mechanism. By arranging the heater, the roller wheel is subjected to initial set through the heater, and then the ink scraping action is conducted through the scraping knife; when the protruding ink is scraped through the scraping knife, the ink connected with the protruding ink can be taken away by the scraping knife, and a recessed part is generated on the roller wheel; and acquisition is conducted through imaging, ink jet is conducted on the recessed part by controlling an ink jet box through the controller, and the surface of the roller wheel is made to be uniform and level.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a scraping device of mimeograph equipment. Background technique [0002] In the scraping structure of the existing mimeograph equipment, the main scraper is set close to the upper end of the roller, and the distance from the ink liquid level is higher. Excessive ink picked up by the roller from the ink tray will scrape off the roller at the main scraper and accumulate droplets. Falling back into the ink tray, this makes the ink liquid level unstable and fluctuates, and the ink attached to the position just turned out of the ink liquid surface on the roller will be stained again and flow back into the ink tray, resulting in incomplete ink staining of the roller , the printed pattern or text is incomplete. Contents of the invention [0003] Aiming at the above problems, the present invention provides an ink scraping device with simple structure, convenient operation and improve...
