 Correct use of slotting knives of flexo printing slotting machines

Carton printing, slotting machine, forming machine, as well as various printing, die-cutting, slotting and other multi-functional combination machine, with high quality, high education, compact structure and so on, it is widely used in carton packaging enterprises. Slotting cutter is the necessary tool, and its service life directly affects the slotting quality and manufacturing cost of the carton. It is one of the problems that need to be improved in quality management and cost management of similar enterprises. Cutting tool wear is related to paper cutting. When the slotting knife works, the cutting edge produces a cutting motion on the board, and the surface is subjected to relative friction. In many cardboard, the sand content is higher than that of 5%~l0%, and the sand has a sharpening effect relative to the edge of the blade, so that the metal on the edge of the blade is gradually plastically deformed and fatigue wear off. The service life of the tool decreases with increasing use time and the amount of sand (quartz sand) and impurities in the paperboard. www.chinacartonmachine.com

Some similar problems of carton printing slotting machine: one is slotting knife (knife) can only be used once, short service life; two is the knife with poor effect, grooving quality instability; three is the resistance of the cutting edge is poor, some local edge crack phenomenon; four is frequently added a new knife, spending large, high production cost. To improve the life expectancy, this article refers to some objectively difficult or unavoidable factors that affect the life of a tool because of accidental bumps. Through subjective efforts, the practical solution is to solve the problem of old knife reuse and new knife selection, thus prolonging the service life of slotting knives.

In today's price to the quality as the core of the fierce competition in the market, this problem is more and more concerned about enterprise leadership, promote enterprise innovation potential, efficiency savings, connotative development road. This paper discusses how to improve the service life of slotting knives. The slotting knife includes two parts, the upper knife and the lower knife. The common upper knives include arc knives and arc saw knives, while the lower ones have half circle sharp angle knives or half round right angle knives, semicircle grooves and wide gear rings. Two. The service life of slotting knives depends on whether the quality of slotting is up to the standard of the products. Slotting quality generally decreases with the cutting edge of the tool edge. It will produce burrs, burrs, cracks and scraps. When the product does not meet the standard, the slotting knife needs to be replaced.
