Design features: *Cardboard transmission adopts vacuum adsorb equipment, with wind control. Keep flute profiles stable under high-speed working condition. *Ventilator keep the corrugated paper in 180¡ãnegative pressure zone of corrugated roller, with vaccum tank, to complete the corrugation. *Air draft groove of lower corrugated roller is less than 2mm, made no stripe mark on single corrugated cardboard. *Gimbal transmission with unattached drive box¬more stable transmission¬reassuring feeding and higher self- maintenance *Reducer casing adopts oil bath lubrication and shut form gear transmission, make little mechanical vibration. *Auto-cyc supply glue, pneumatic control of glue supplying and returning, with buffering effect. *Glue roller surface are treated by special mesh snicked and chromeplated. *Upper and lower corrugated rollers are made of 48crmo high quality alloy steel¬after heat-treatmntits rigidity is hrc58-62¡ã¬the surface are whetted and plated chrome *Flute profile: available discretionarily Any problem, contact
