What should I do if the corrugated cardboard production line has uneven corrugation?

2019-09-10

The uneven height of the corrugation is manifested as: a very small height difference between adjacent corrugations and the adhering surface, resulting in an uneven surface of the cardboard, which can reduce compressive strength. The occurrence of double-sided corrugation can cause great harm to the subsequent printing process.

Causes and Solutions

① Uneven temperature on the surface of the corrugating roller ① Check whether the condensate drainage meets the requirements.

② Abnormal operation of the corrugating roller ② Check the condition of the bearings at both ends and the transmission part ③ Inconsistent bonding gap of the corrugating roller ③ Adjust and correct the bonding gap of the corrugating roller ④ Dirty surface of the corrugating roller ④ Clean the corrugating roller to keep it clean ⑤ Improper gap between the glue roller and the floating roller ⑤ Adjust the gap between the two ⑥ Poor quality of the adhesive ⑥ Check and remake the adhesive.

⑦ Uneven moisture content in the corrugated base paper, low tension ⑦ Proper preheating treatment to increase tension control.

⑧ Uneven paper bridge ⑧ Properly adjust tension control.
