When the paper mounting machine is not properly adjusted or maintained, it is easy to cause errors in the mounting of face paper and corrugated board. Therefore, we should adjust and maintain the mounting machine regularly.

　　1. The paper feeding chain mechanism of paper mounting machine is loose, which makes the upper and lower chains work inconsistent or unstable, resulting in errors. Therefore, the paper mounting machine chain should be timely cleaned, cleaned, and maintain good lubrication.

　　2. The front gauge on the upper and lower chains is loose, which causes the impact on the edge of the paper when feeding, resulting in errors. For the loose front gauge, corresponding measures should be taken in time.

　　3. A certain amount of glue is accumulated in the upper and lower rollers because they are not cleaned frequently, which hinders the synchronous rolling transportation of tissue paper and corrugated board, resulting in errors. The glue liquid or dirt on the upper and lower roller should be removed frequently.

　　4. The contact position of the sheet is not suitable or the gap is too large, which does not slow down the inertial impulse of the paperboard at high speed, resulting in errors. Should timely adjust the position of the pressure paper steel strip, so that it and the cardboard to maintain a certain friction, to prevent excessive feeding and advance.
