3. Structure and operating principle.

The single facer roll the basic paper into waveform rubberized corrugated paper,then suction with the facial paper so as to make the satisfactory corrugated cardboard after instant pasting.

3.1 The upper and lower roller comprised single facer roll basic paper into waveform corrugated cardboard.It is the important indicator for corrugated roller’s fit pressure,parallelism and appropriate.

3.2 Pressure roller

Pressing on facial paper and gummed waveform corrugated paper to stick firmly,then formed the single corrugated paper.

3.3 Preheating roller

Keep certain moisture,basic paper baked by the preheating roller so as to favorable corrugated shape and well stick.

3.4 Gluing system

The main function is coated with a layer uniform paste on the flute.Compose of glue roller,groove,spreading roller and glue circular device,which is direct influence the cardboard suction strength.The gap between spreader roller and glue roller is 0.3-0.45mm.It controlled by electric adjustment,attached digital display function.

3.5 Heating system

Heating for the corrugated roller,pressure roller and preheating roller.The heating source are vapour,gas,oil and electric and so on.Whether which kind of heating form,it must keep about 170°C for surface temp.It must attached good suction device for uneven temp and low heating efficiency caused by condensate water storage in the vessel. The gap between siphoning installation mouth and corrugated roller wall no more than 0.8mm,but no less than 0.3mm for timely emission.

3.6 Pneumatic device

The gap adjustment between corrugated roller and pressure roller by the pneumatic device.

In order to guarantee the pneumatic device system working in good state should guarantee both the the air compressor and the pneumatic components normal work.The pneumatic components work pressure is 0.4 Mpa.Ensure the pneumatic components'S all sealing material quality and reliable.

3.7 Paper guiding board and vacuum adsorption device

The core component of Single machine is upper and lower corrugated roller.The parallelism and gap between upper and lower corrugated roller is very important. In addition, due to the corrugated roller high speed running caused centrifugal effect, the corrugated paper break away from roller. The paper guiding board and vacuum adsorption device completed both the nice binder state and no ditching of the corrugated paper.

At present, most of the corrugated board production equipment which the base paper pass into corrugated roller and form waveform shape used the guiding board. Guide board position must be correct, It is an important role for the quality of cardboard. The distance between guiding boards must keep pace with the gap of upper roller and glue roller'groove.The gap between guiding board and upper roller: A ;0.5 mm;C: 0.45 mm;B : 0.4 mm.Meticulously adjust the distance avoided the squeeze and knead which is impact on quality.

The gap between adsorption cover'copper board and upper roller is 1 ~ 3 mm, copper plate and the lower roller is about 0.1 ~ 0.2 mm (should open the lid of observation visual adjustment)
