N Inside Vacuum Suction Single Facer

1.On the end surface of the corrugating rolls there are many through holes which connect the two ends, these through holes are interconnected with many inconsecutive slots on the surface of the corrugating rolls. Through these through holes and slots, exhaust fans absorb corrugated paper surround the corrugating rolls about 180 degrees where is positive-pressure-zone. As these slots are inconsecutive and are no wider than 2mm, there are less stripes on the corrugated board, the tensity and quality of the corrugated board is enhanced. Air-compressors equipped with deafen devices.2.The independent oil-bathed gear box, universal joint drive the corrugating roll, pressure roll, application roll and meter roll, which is separated from dynamics oscillating service, improves running stability and flute formating precision. Air motors are vacuum inhale air-compressors.3.Corrugating roll is made of high quality alloy steel 48CrMo and diameter is φ 263mm, the surface is medium-frequency quenched and chrome-plated. its hardness can reach HRC58 60, which ensures good wear-resistance and long life service.4.Independent glue clean device and electric glue-separate board to control the width of glue, suitable for different width of cardboard. Spreading gap can be regulated according to different production speed and paper width. Glue roll clean motor function independently. The number of net points is 25/m2.5.Lubricated by high temperature lubricate grease.6.Preheating rolls, pressure rolls and corrugating rolls all meet the National Standard of Pressure Vessel . Working pressure is 1.1MPa.7.Corrugating roll diameter: 280mm, 325mm, 360mm, 410mm. Maximum width is 2500mm.8.Maximum production speed: 120m/min, 150m/min, 180m/min, 200m/min.
