Problems solved by technology

However, when the distance between the squeegee and the ink cartridge is close, the distance between the squeegee and the contact point of the ink roller and the plate cylinder is relatively long, resulting in the ink between the squeegee and the contact point of the ink roller and the plate cylinder There are problems of flow and uneven distribution in this transmission distance, which affects the printing effect
If the squeegee is moved closer to the contact point between the ink roller and the plate cylinder, the distance between the squeegee and the ink cartridge will be larger, and the ink scraped off the ink roller cannot be effectively dripped into the ink cartridge. Therefore there is room for improvement

Abstract

The invention discloses an ink scraping plate structure of a printer. The ink scraping plate structure is characterized by comprising a scraping plate, an ink receiving slot and a flow deflector, wherein an ink outlet is formed in the slot bottom of the ink receiving slot; the ink outlet is connected with a guide tube; the scraping plate is positioned on aslot openingof the ink receiving slot; one end of the scraping plate is a fixed end, and is fixed on the inner side wall of the ink receiving slot; theend back to the fixed end is an ink scraping end and extends to the outer side of the ink receiving slot; the first end of the flow deflector is connected onto the ink scraping end, and the second end of the flow deflector extends into the ink receiving slot; and the first end is higher than the second end. The ink scraping plate structure can scrape ink at the position close to a contact point of an ink roller and a printing plate roller, and also effectively enables scraped-off printing ink to flow back into an ink box.

Description

technical field [0001] The invention relates to a printing machine, in particular to a squeegee structure of the printing machine. Background technique [0002] The flexographic printing machine uses fluid ink with strong fluidity. The ink is transferred to the graphic part of the printing plate by the ink roller and the printing plate cylinder to make it inked. The ink is transferred to the substrate, and finally the printing process is completed on the dry side. [0003] In the process of inking and printing, the printing machine needs to use the squeegee to scrape off the excess ink on the ink roller, so as to avoid the situation that too much ink causes waste and affects the printing quality. In the prior art, the distance between the oil scraper and the ink cartridge is relatively short, so that excess ink is scraped off from the ink roller and directly falls into the ink cartridge for recycling, and at the same time, the ink on the ink roller is evenly scraped. Howev...
