The cross cutter is an important piece of equipment in the corrugated cardboard production line. Its function is to cut the cardboard into finished products according to the set length. The cutting length of the cross cutter directly affects the size and quality of the carton, so if there is a problem that the length of the paper cut by the cross cutter is not the same, it is necessary to find out the cause and solve the problem in a timely manner. According to experience, the possible causes of this problem are as follows:

    1, the dryer speed is not stable. Dryer is used to dry and shape the cardboard equipment, if the speed is not stable, it will lead to cardboard before entering the cross-cutting machine deformation or stretching, thus affecting the cut length of Seidu.

    2, cross-cutting machine drive system failure. Cross-cutting machine is controlled by industrial control computer, according to the set length control knife shaft operation. If the transmission system failure, such as loose belts, gear damage, circuit breaks, etc., will lead to computer signals and the actual operation is not synchronized, resulting in errors.

    3, cross-cutting machine parameter setting error. Cross-cutting machine needs to be used before the cardboard type, thickness, humidity and other factors to set the appropriate parameters, such as cutting speed, cutting pressure, cutting interval, etc.. If the parameters are set incorrectly or not suitable for the current situation, it will lead to unsatisfactory cutting results.

    So for the above reasons caused by the cross-cutting machine cut out of the paper length is not the same problem, we need to how to avoid it? This requires us to pay attention to the following points when using the cross-cutting machine:

    1, regular inspection and maintenance of the dryer and cross-cutting machine drive system to ensure its normal operation.

    2、Adjust the parameter settings of the cross-cutting machine according to the actual situation and carry out test verification.

    3、Recalibrate the cross cutting machine every time the cardboard type or batch is changed, and check whether the cutting results meet the requirements.
