Abstract

The utility model discloses a printing roller ink scraper capable of being externally connected, which comprises a supporting shell, an even number of symmetrical rolling shafts are rotatably arranged in a groove of the supporting shell, and the supporting shell is connected with a supporting plate through a sliding shaft and a spring. The supporting plate is rotationally provided with a bent swing rod, the swing rod is provided with a limiting rack, and the inner supporting rod and the outer supporting rod are connected through a limiting sliding frame. A long shaft of the outer supporting rod is provided with a limiting rod matched with a limiting rack ratchet wheel. The ink scraper is composed of a sliding seat, a sliding rod, a mounting rod and a scraper. The ink scraping device can be directly installed on the upper printing roller shaft and the lower printing roller shaft and is suitable for printing rollers of various specifications, the ink scraping angle and position are flexibly adjusted through cooperation of limiting and the ratchet wheel and buffering stable supporting of the spring, the problems that a traditional ink scraping device is poor in installation adaptability, inconvenient to adjust, insufficient in stability and the like are solved, and the ink scraping effect of the printing rollers and the device universality are improved.
