INK SUPPLY MECHANISM OF SCREEN PRINTING MACHINE

摘要

PROBLEM TO BE SOLVED: To arrange an ink supply mechanism effectively even when the distance between a printing squeegee mechanism and an ink scraping scraper is narrow, to miniaturize the ink supply mechanism, to prevent the outflow of ink from the tip side of a nozzle with the solenoid valve of an ink tank closed, and to control the supply of the ink freely. SOLUTION: A flexible tube 21 to be the tip of a passage for supplying the ink 13 of the ink supply mechanism 11 is arranged in an interval part between a printing squeegee 15 suspended from a squeegee head part 9 and a scraper 17, and a tube clamping mechanism 31 which can press the tube 21 is arranged in the vicinity of the tip part of the tube 21. The tube clamping mechanism 21 has a clamp base 33 facing one side of the tube 21 and a clamp member 37 facing the clamp base 33.
