  SF-280E Single Facer

Specification:

Design speed: 80m/min, normal work speed: 60-70m/min

Machine Introduction:

1. Vacuum suction Fingerless design provides perfect flute formation in high speed manufacturing.

2. Individual immersion oil gear type drive box, separating dynamic vibrations improve running stability, easy and fast for maintenance.

3. The exhaust fun motor drive suction case, absorb corrugated paper surround the corrugating rollers about 180 degree where is positive-pressure zone, make sure big strength for flute making.

4. Steam heating type adopt triplex gimbal drive, work steady.

5. With “Self-circulating glue feeding system”, save glue and improve work efficiency.

6. Pneumatic control for pressure roller load/unload, with cushioning effect.

7. Gear box adopt submerged lubrication, enclosed gear drive, reduce machine shake, ensure high speed running.

8. Automatic added lubricate oil system.

9. The steel blank on top of machine can separate disconnect to clean garbage inside, not need disconnect whole machine.

10. Adjust glue thickness: Quantity of pasting glue and controlling glue is controlled by the clearance between glue roller and doctor roller adjust by manual

11. Glue width adopt manual adjust.

Raw materials & purchased components:
