The quality of corrugated roller will directly affect the cost of corrugated paperboard production. Generally, enterprises will periodically roll over the corrugating roller. Then, what are the factors that affect the corrugated cardboard? Let's discuss it below.

I. corrugated roll pitch

Pitch distance is the distance between two arris ends, and others are calculated by the number of corrugations in a certain distance. From the general corrugated is bad for printing, but the distance of the corrugated corrugated corrugated rate is relatively low, can reduce the amount of corrugated paper, but the influence of corrugated cardboard marginal pressure.

Two, corrugated roll height

The middle two high corrugated corrugated peak valley distance, the higher the general corrugated made out of cardboard corrugated paper side pressure is stronger, more is the board thickness is high, but relatively low pressure flat cardboard, corrugated roller is also relatively easy to wear.

Three 、 middle height of corrugated bar

In order to roll the rollers in parallel and press them in parallel on the core paper and inner paper, the lower corrugating roller usually has a certain height. Some of the rollers are of medium height and some of them are not. This is based on the different equipment characteristics. The so-called middle and high, that is, the middle part of the corrugating roller diameter is greater than the diameter of both ends of the corrugating roller, generally between the 30-60 silk, and the amount of medium and high depends on the roller diameter, width and material quality and other factors.

Four. Diameter of corrugating roller

The greater the diameter of the corrugated rod, the better the rigidity, the higher the less, the roll can store more steam, the smaller the vibration, the easier to operate. The disadvantage is that the core paper contact surface is large, resulting in greater tension of core paper.

Five 、 roller gap

When the upper and lower corrugating rollers bite, the gap of the corrugated wall is too small, which will cause the corrugated core paper to rupture and influence the corrugated strength. If the gap between the teeth is too large, the resonance of the corrugated roller will be increased.

Six, corrugated rate

After the corrugated forming, the length of the straightening is compared with the length that has not been straightened. In general, the higher the rate of corrugated, the more paper used, if the same material, the edge pressure, the greater the intensity, the lower the flat strength.
