Guideless single-sided machine related cardboard defects-3

Loose-faced paper, the initial bonding of the tissue paper and the core paper, and separation means that the corrugated medium paper and the tissue paper are separated. This situation is often mistaken for the fact that the face sheet becomes loose on the lower corrugating roller, but loose face paper is only visible on the inclined conveyor.
The distance between the corrugating roller and the top roller is too large or too small The gap between the rubber roller and the rubber roller is too large or too small The gap between the corrugating roller and the pressure roller is too large or too small Corrugating roller or pressure roller Upper Thermal Insufficient Corrugated Roller Pressure is too low or the pressure between the lower corrugating roll and pressure roll is too low Core paper is too wet Vacuum degree is too high Gelling temperature is too high, viscosity is too low Web tension is too high Pressure roll rotation is not flexible Single The surface of the machine is shaking the surface of the paper. The core paper is too dry. The lifting of the conveyor belt is insufficient. The tension of the conveyor belt is uneven. The single-sided machine suddenly accelerates. The lifting conveyor cannot be kept in line with its speed.

Measure

Adjust the spacing, calibrate the readings to adjust the spacing, calibrate the readings to adjust the spacing, calibrate the readings to check the temperature, siphon, see if there is condensate deposit check pressure in the roller, check the pressure regulator, check the parallel condition to check the humidity, wet marks, increase the pre-regulator Roll angle reduction Vacuum degree Check the glue status Check the tension of the surface paper and the core paper, if necessary, adjust the lubricant. Check the bearing and sleeve Check the single-face machine acceleration rate Check the humidity, dry marks, reduce the wrap angle, increase steam injection Check the acceleration and make corrections, check if there is any worn or sliding conveyor belt. Check the edge of the conveyor belt to see if the edge of the conveyor belt, cause the cardboard fluffing when the tension roller or the drive roller check the sprocket teeth and chain drive on the lift conveyor belt,
See if the chain intermittently skips the sprocket teeth to check the acceleration ratio of the single-plane and lift conveyors to ensure consistent acceleration
