    In the production process of corrugated cardboard production lines, various problems may arise from time to time. One very common issue is poor adhesion, which is specifically manifested as follows: after the cardboard has been initially glued for 5 minutes, under external force, the inner, outer, or A, B flutes or the core are completely separated, and all paper fibers remain intact without being pulled or fuzzed. The adhesive area shows white or colorless strips of paper with no fiber attachment. Causes and Solutions: 1. Excessive tension on the face paper - Adjust the brake device to reduce friction. 2. Excessive moisture in the face paper and core paper - Increase the preheating of the face or change the paper, and reduce the speed. 3. Insufficient adhesive application - Increase the amount of adhesive applied. 4. Imbalance between the glue roller and the floating roller - Adjust the reasonable gap between the two. 5. Malfunction of the lifting mechanism of the canvas - Check the hydraulic pressure device and mechanical adjustment system. 6. Poor quality of adhesive - Correct the quality of the adhesive and use a suitable adhesive. 7. Insufficient heat, poor starch gelatinization - Check and eliminate factors causing insufficient heat. 8. Excessive heat, premature starch coagulation - Properly reduce preheating or decrease pressure. 9. Adhesive forming lumps, uneven application - Address the quality of the adhesive.

    What should be done if corrugated wrinkles occur during the production process of the corrugated cardboard production line? You can try to solve it from the following aspects: 1. If there are wet spots or material spots in the corrugated base paper in the forming or width direction, this phenomenon can be resolved by increasing the angle of the preheater. 2. If the forming force of the corrugated base paper is not strong enough, it is necessary to increase the balance tension of the forming force and pay more attention during the production process. 3. If the parallelism of the corrugating rollers is poor, simply correct or adjust the parallelism of the corrugating rollers. 4. If the moisture content of the corrugated base paper is uneven, appropriate preheating or steam spraying is needed to maintain moisture balance.

    During the production process of corrugated cardboard production lines, the issue of corrugated paper breaking can occur during the fluting process. The breaking of corrugated paper is an important indicator for assessing the adaptability of corrugated paper. The reasons for this issue include: 1. Preheating tension of the single-sided machine 2. Brake of the corrugated paper 3. Bending and shearing forces encountered when entering the upper and lower corrugating rollers. Solutions: ① Poor quality of the corrugated base paper, replace the corrugated base paper. ② Wear of the corrugating rollers, perform simple repairs or replace the corrugating rollers. ③ The gap between the corrugating rollers is too small, correct and adjust the fitting gap of the corrugating rollers. ④ Mechanical damage during operation, check and repair damages caused by improper mechanical handling. ⑤ Brakes are too tight, reduce the air brake pressure.
