One of the common problems and maintenance of corrugated board production line

1 common faults and troubleshooting in the process of corrugated board

is still at the lowest level in the industrial industry. 1.1 the height of corrugated board is not enough, and the reason may be that the pressure or temperature is too low, or the water content of the paper is too high. The solution is to adjust the pressure or roll temperature, or reduce the speed, such as the maximum bearing capacity of your material sample, whether to choose computer series products, whether to test one parameter directly, so that the paper can be dried

1.2 the corrugated height is uneven, and the length of both sides of the extruded corrugated paper is different, showing a fan. This is due to poor parallelism of the corrugating roll or uneven pressure at both ends. If the corrugated paper on the left is shorter than that on the right, the left side of the upper corrugated roller should be raised appropriately, otherwise it should be adjusted in reverse

1.3 the corrugated paper curls into a barrel shape, mainly because the temperature difference between the upper and lower rollers is too large. Check the working condition of the heating source in the upper and lower rollers. If one of them fails, it can be repaired or replaced

1.4 the corrugated paper is adhered to the corrugated roller surface. This phenomenon usually occurs when the roller surface temperature is too high or the moisture content of the base paper is too high. At this time, the temperature of the roll surface should be adjusted to dry the paper. 3. Then turn the hand wheel and press the ridge. If the scraper does not fit the roll groove, it should be adjusted or replaced
