SF- 270 Corrugated Fingerless Type Single Facer

Introduction:
The single facer is the primary piece of equipment used in the production of corrugated paperboard. The fingerless single facer features a vacuum suction component that greatly increases production precision.

Characteristics:
1. Cover vacuum suction.
2. The corrugating roll is made of high quality alloy steel 48CrMo.
3. No gear transmission.
4. Glue roll is lifted and lowered pneumatically.
5. Independent glue cleaning device and electric glue-separating board to control the width of glue application.
6. Manually regulate or electrically regulate the display device.
7. Lubricated by high temperature grease.
8. The surface of all dancing rolls and preheating rolls is grinded and chrome-plated.
9. Pressure roll is medium- frequency quenched and chrome-plated.
10. Width 1400mm~2000mm.
11. Working pressure is 1.1MPa.
12. Corrugated roller diameter:270mm

1. A vacuum system is placed within the outer housing, comprising a high-pressure blower and noise reduction silencer. Pneumatic and electrical controls come in an electrical enclosure, which is 1.5 meters from the corrugating machine. A protective cover is also available for maximum operator protection.
2. The base and side frames are constructed from heavy-gauge cast iron in 130mm thickness. Gearbox is built separately from the machine frame and comes with a universal joint.
3. Corrugating rolls are made from 48CrMo alloy steel that receives laser hardening and grinding processes to achieve HRC60 hardness. Roll diameter: 280mm. Bearings are included. Pressure roller withstands high temperature.
4. Pressure roller diameter: 324mm. Receives grinding, tempering and chrome plating processes. Pneumatic cylinder is used to control its up and down movement. Steel grade: 45#, medium carbon content.
5. Pneumatic control supply or reback the glue, coating glue roller diameter 215mm ,surface after grinding ,carved 25 line steel pit anilox , then chrome plated , even glue roller after grinding then chrome plated .
6. Corrugated roller and pressure roller materials are supplied by zhongyuan Tegang. Corrugated roller: 0.15mm, in medium height; pressure roller single side: 0.075mm in medium height.
Pressure cylinder diameter: 160mm
Pre-heater diameter 320mm, made of seamless steel, connected by steel braided hoses.
