The corrugated roll former of Bosj has high wear resistance and longer life. It reduces the time of overhauling and greatly reduces the production cost. However, the anilox roll is a key component of flexo printing, whose performance directly affects the print quality of the product.
Cause analysis of blistering of inner paper of achincorrugated sheet roll forming machine：
① The preheat of the corrugated paper is insufficient;
② Insufficient brake tension on the tissues;
③ Insufficient preheating cylinder temperature at start-up;
④ The pressure rollers are worn or not parallel;
⑤ Rubber covered rollers are worn, some of them are difficult to be glued, or there is a foreign substance entering between the gluing roller and the measuring roller.
⑥ The suction chute in the corrugated roll section is blocked and the guide board is worn.
① Increase the preheating area of the corrugated paper;
② Tighten the brake gate valve;
③ Wait for the temperature to rise to 180°C, then renew the paper and start the machine;
④ Replace grinding pressure rollers or adjust to parallel;
⑤ Replace the glue spreader and remove debris between the glue spreader and the dosing roller;
⑥ Clean the corrugated roller suction chute, corrugated sheet making machine, and replace the guide sheet.
