Raw materials used on single facer

Raw materials used on single facer

Raw materials include base paper and starch. These two substances are very important. The following brief introduction is about the output and production speed of these two substances.

The base paper used on the single facer is in good condition. The thickness of the face paper is uniform and appropriate, and the moisture content is about 6% or 7%. The moisture content difference of the whole paper sheet cannot exceed 1%. If the influence of good weather on the original paper roll is not noticed during transportation or storage, the paper web edge may fall off, so the paper roll shall be accepted when it is transported to the warehouse. When the machine is running, the face paper web reaches the single facer under the control of sufficient and balanced tension. Enter the machine at a high temperature of 160 to 180 degrees after being preheated, as close as possible to the single facer. A complete preheating device shall be provided above the paper feeding of the single facer to prevent heat loss. www.chinacartonmachine.com

For the formed corrugated core paper, small and even tension shall be used, and steam with low pressure shall be used for preheating and pretreatment, and it shall be close to the single facer as far as possible. After the face paper passes through the paper feeding section. Take special care to prevent the paste from getting onto the surface of the corrugated roller or extruding at the edge of the paper. This is particularly important for the adsorption type claw free single facer.

To accurately arrange the two sheets of paper, the ideal way is to use an automatic system, which is convenient for operators to operate. This can prevent the glue from settling on the hot roll and reduce the degree of edge repair.

On the tile line, the use of laser scanning equipment with large tolerance and high degree and CCD camera can realize the high accuracy paper arrangement from the paper roll to the double facer.
