Features:
◆ Fingerless vacuum suction structure with fan adjusting devices, keeping the proper form of the flute during high speed running.
◆ The upper and lower corrugated rolls are made of 48CrMo high quality alloy steel, with the heat treatment and tungsten coating. The hardness is above HV1200.
◆ The pre-heating roll of the top paper and the steam spraying system of the corrugated board are installed in the machine.
◆ Upper and lower corrugated rolls are independently from the main frame, which could be lifted for changing the flute type.
◆ The glue and doctor rolls are installed on the slide together for the change, which saves the time.
◆ Lifting of the upper corrugated roll, pressure roll and glue roll are pneumatically controlled.
◆ Frequency motor, independent geared box, three axis drive. Speed adjustment is achieved by the frequency motor, which can save the power and connect with production management in future.
◆ Closed and oil immersed type lubrication, steady, low noise and long usage time of the gears.
◆ The amount and applying width of the glue is controlled electrically or manually. The gluing system can operate independently during the pause of the plant which could avoid the drying of the glue.
◆ Auto recycling glue system.
◆Glue roll is accurately embossed and hard chromed.
◆ The bearings of corrugated rolls and pressure roll are lubricated with high temperature grease, enlarging the life and smoothing the running.
