Features

• Fingerless type corrugated single facer machine.
• Cardboard transmission is achieved by the method of vacuum suction, it equipped with high pressure air blower as well as a muffler, with adjustable of air blowing rate, to keep flute profiles stable under high speed.
• All the corrugated rolls, pressure roll, gluing roll are pneumatically controlled, and the air control unit and electrical control unit are concentrated in on cabinet, the operation side is fully enclosed.
• The main structure and frame are made of cast iron, up to the thickness of 120mm, equipped with submerged lubrication system to avoid noise and keep running stable.
• The shafts of corrugated and pressure roll are all heat resisting and lubricated by lubricating grease.
• The corrugated roll is made of 48CrMo alloy steel treated with hardening and tempering, grinding, laser-quenching, the hardness up to HRC58^o.
• The pressure roll is made of 45# medium carbon steel, with the treatment of hardening and tempering, grinding and chrome plated, the roll up and down is controlled by cylinder, and equipped with buffer device.
• The gluing roll is treated with grinding, mesh snicked and chrome plated on the surface, while the doctor roll has the same treatment. The glue supplying is controlled by pneumatic.
• The pre-heater is made of seamless steel tube, and connected by flexible metal hose.
