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, a pressure roller 8 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 the controller, and the pressure roller 8 is located between the imaging mechanism and the inkjet mechanism and is used for bonding the roller, The pressure rolle...

Abstract

The invention provides a novel ink scraper. The invention provides the novel ink scraper which has a simple structure, can be operated conveniently and can increase reliability of ink scraping. The novel ink scraper comprises an oil ink disk, a roller and a scraper, wherein the oil ink disk is used to store oil ink; the lower part of the roller is sunk in the oil ink of the oil ink disk; and the scraper is disposed on the oil ink disk and located on one side of the roller. The novel ink scraper also comprises a heater, a controller, an imaging mechanism, a pressing roller and an ink spraying mechanism. The heater is disposed, so that initial condensation can be conducted by the roller via the heater; ink scraping is then conducted by the scraper, and the scraper will take away the oil ink connected with the raised oil ink during scraping of the raised oil ink, so that the roller will get sunk; and then, collection is conducted through imaging, one-time rolling pressing is conducted by the pressing roller, the controller controls an ink spraying box to spay ink to the sunk part, and the pressing roller carries out second-time rolling and pressing, so that the surface of the roller becomes even and smooth.

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 a novel ink scraping device with simple structure, convenient operation and im...
