The invention discloses a slitting
system of a galvanized pull-ring strip, and relates to the field of
machining of pull-rings of ring-pull cans. According to the technical scheme, the slitting systemis characterized by comprising a
machine tool, a transmission roller and a
cutting mechanism are arranged on the
machine tool, the
cutting mechanism comprises a
cutting roller and a cutting motor, acircular cutter is arranged on the cutting roller, the
machine tool is provided with a trimming mechanism and a driving mechanism, the trimming mechanism comprises a trimming piece and a trimming strip, the trimming strip is provided with a knife grinder, an oil cavity and a
piston channel, the trimming strip is provided with a movable plug, the trimming piece is provided with a driving
piston, and the
machine tool is provided with a cleaning mechanism for cleaning up
cut scrap iron. Through the trimming mechanism, the circular cutter can be kept sharp so as to more easily
cut off a galvanizedcoiled strip, no burrs can easily appear, and the cutting quality is high; by arranging a
piston rod, a driving pawl and a
ratchet wheel, the service life of the knife grinder is long; and by arranging the cleaning mechanism,
scrap iron can hardly be left on the surface of the galvanized coiled strip to influence the subsequent
machining of the galvanized coiled strip.
