Multi-Cassette Positive Pressure Single Facer For Corrugated Paperboard

Designed speed: 250m/min
Effective width: 1400mm--2500mm
Main corrugating roll diameter: 405mm (varies with different types of rolls)
Pressure roll diameter: 495mm
Preheating roll diameter: 420mm

SF-405M multi-cassette positive pressure single facer is designed for forming single face corrugated paperboard. Firstly by heating, it can make fluting medium into fluted corrugated sheet, and then through glue coating, linerboard heating, and bonding between the medium and linerboard, the single face corrugated cardboard is achieved.
SF-405M is a key piece of equipment in a three-, five-, or seven-ply corrugated fiberboard production line. The corrugating rolls can be integrally mounted onto or dismounted from the machine, so the machine can complete roll exchanging in 10 minutes, and operators only need to press several buttons.  During the process, a trolley is utilized to deliver the new corrugating rolls to a platform of the machine. Driven by a hydraulic motor, the platform then delivers the rolls to the right position to be hydraulically locked and secured on the machine base finally.

 

1. Due to positive pressure design, SF-405M multi-cassette single facer comes with low heat loss, and offers uniform pressure to the medium paper. Thus, the medium paper attaches to corrugating rolls uniformly as well, which assures forming of high quality flutes. Due to uniform pressure, the flute tips can be evenly coated with adhesive, so as to ensure effectively lamination with the flat linerboards.
2. The main and auxiliary corrugating rolls are made of high quality alloy steel. After heat treatment, and fine surface polishing, the rollers are additionally sprayed with a layer of tungsten carbide coating to ensure hardness, wear resistance, and strength.
3. The corrugating rolls and pressure rolls are controlled by a hydraulic system with high stability, and they also have the cushion effect as controlled pneumatically. The gap among the rollers can be adjusted electrically to ensure accuracy.
4. The positive pressure single facer is designed with an electric glue amount control unit, and an electric gluing width control unit as well. The gluing unit is capable of running independently to avoid adhesive drying up, and its movable design makes it convenient for cleaning, repairing, and maintenance.
5. User friendly designed, the equipment features simple operation. To illustrate, it comes with Function Selection, Parameter Setting, Failure Indication and Trouble Shooting functions, as well as a touch screen operation panel to show operation status via colored graphics.
6. Its pre-conditioner is built with a steam spraying system functioning to adjust the temperature and moisture content of the corrugated medium.
7. The single facer uses a high strength synchronous pulley for driving. The bearings for its corrugating rolls and pressure rolls are all lubricated by high temperature resistant grease so as to assure long service life, and smooth running.
