The general structure of corrugated board single-side machine is composed of paper guide roller, preheating roller, upper and lower corrugating roller, pressure roller, pressure cylinder, lower preheating roller 1, lower preheating roller 2 forming compound device and including coating roller, uniform rubber roller, pulp plate and other coating mechanism.
Corrugated base paper by paper guide roller to adjust tension, preheat roll control humidity, sliding on top corrugated roller stare blankly into the heat conduction oil heating up and down between corrugated roller corrugated channel, steam heating corrugated roller used for heating, in the center of the two roller mesh point in the middle of the pressure after pressing molding, close to the next tile type x roller stare blankly on the run to the center of the rubber roller and the corrugated roller attachment, After the excess glue is scraped by the uniform rubber roller, the coating roller which forms a layer of uniform film on the surface is evenly coated with glue on the top of the corrugated paper. The corrugated paper after sizing continues to run with the lower corrugated roller, and the glue during which is heated gradually gelatinized. At the center line between the lower corrugated roller and the pressure roller, the surface paper reached the pressure roller after humidity control by two preheating rollers is hot-pressed and combined drying, thus producing various types of corrugated two-layer cardboard.
The above process includes a complete process of preheating, ironing, sizing, gelatinization and compound drying of two-layer corrugated board production. The role of steam heater is to heat the corrugated roll to reach the required temperature for production.
In the production process of corrugated machine, one of the key technological conditions is that corrugated paper after ironing must be pressed to the next corrugated roll shape to accurately complete the top part of corrugated paper sizing and compound with the surface paper. Any displacement of corrugated paper on the lower corrugated roll after ironing will cause the formed corrugated deformation, thus producing quality defects such as degumming, high and low corrugated, jumping corrugated, broken paper, agaric edge, inverted corrugated and so on
