The pre-coating film laminating machine has been used for a long time, and it must be maintained. If the laminating machine is adjusted or improperly maintained, it is also easy to cause errors in the mounting of facial paper and corrugated cardboard.
        The problems that often occur in the pre-coating film laminating machine are as follows:
        (1) There is a loose phenomenon in the paper feeding chain mechanism, which makes the working coordination of the upper and lower chains inconsistent or unstable; the front regulations on the upper and lower chains are loose, which causes impact on the edge of the paper when feeding;
        Treatment method: For loose front rules, according to the loose parts, the corresponding tight treatment should be taken in time;
        (2) The contact position of the paper pressing steel strip to the facing paper is uncomfortable or the gap is too large, and it does not play a role in slowing down the inertial impact force of the cardboard at high speed;
        Treatment method: Adjust the position of the paper pressing steel strip to maintain a certain friction with the cardboard to prevent the paper from being too violent and advanced; the glue or dirt on the upper and lower rollers should be cleaned regularly.
        (3) The upper and lower rolling rollers accumulate a certain amount of glue because they are not cleaned frequently, which prevents the synchronous rolling transportation of facial paper and corrugated cardboard

        Treatment method: The chain of the pre-coating film laminating machine is the main component that drives the machine. It must be kept clean, so it should be cleaned, cleaned, and maintained with good lubrication in a timely manner.
