Designed speed: 100m/min
Effective width (paper width range): 1400mm-2200mm
Corrugating roll diameter: 280mm
1. The fingerless single facer is designed to form single face corrugated paperboards. Its vacuum suction design for web guide and air flow adjustment device, ensure stable flute forming at high speed conditions.
2. The upper and lower corrugating rolls are made of quality 52CrMo alloy steel, and then undergo heat treatment to achieve a hardness from HRC58° to HRC60°. The rolls are additionally available with fine surface polishing, as well as chrome plating or tungsten carbide coating, so as to assure higher production speed and longer lifespan.
3. The fingerless single facer is built with linerboard preheating rolls, and a medium paper pre-conditioner. Its separated corrugating roll seat makes roll changing convenient.
4. The corrugating rolls, pressure rolls, and glue-coating rollers are all pneumatically controlled. The bearings for those rolls are lubricated using high temperature grease, which achieves long lifespan and smooth operation.
5. The glue-coating roller and the glue-thickness control roller are used in combination to ensure uniform adhesive applying. The two kinds of rollers are mounted on the same base supported by a guide rail system, so they can be assembled or disassembled synchronously and conveniently. This design also assures easy maintenance.
6. A variable frequency motor is utilized in the main drive system, and an independent driving box and a three-shaft driving system are available. Due to variable frequency drive controlled speed, the equipment is energy efficient, and is also convenient for production management.
7. The fully enclosed gear transmission system design, coupled with oil bath lubrication method, assures smooth transmission and extended gear lifespan.
8. The reduction gearbox for the drive system is lubricated by submerged lubrication method, which reduces operation noise. Due to universal joint drive, the machine is isolated with the driving motor, contributing to smooth and safe operation.
9. The gluing unit comes with two working modes. One is start and stop working with the fingerless single facer, and the other is to run independently. All glue-coating rollers are chrome plated to offer better wearing resistance and higher surface hardness, and they also come with embossed patterns to ensure good glue adhesion. To ensure convenience use, the unit is able to supply glue circularly. Additionally, the gluing width can be manually or electrically controlled to match with the medium paper and flute width.
