Why does the slitter blade have deviation?

1.    Caused by improper adjustment of the blade feeding positioning baffle. It may also be due to the fact that the blade used is too dull in a certain part, and the linear speed of other knives is different. Or it is linear speed of other knives is different. Or it is caused by the unreasonable adjustment of the paper guide roller of the blade. Targeted measures should be taken for different reasons.

2.    After being processed by the slitting machine, there are burrs. The main reason for this problem is that the blade used is dull and needs to be re-sharpened. In addition, it may also be caused by the overlapping of the blade and the knife groove too shallow, or the paper edge or paper wool being caught in the knife groove. At this time, it should be cleaned and adjusted in time, and then restart the production. At the same time, pay attention to check whether the kerf clearance of the blade is reasonable. If necessary, it should be adjusted. Usually, it should be kept within 2.5 mm.

3.    The indentation line of the slitter blade is often broken. In response to such a problem, there are mainly two reasons, one is that the base paper used is too poor, and high-quality base paper needs to be selected; the other reason is that the pressure line is too deep and should be readjusted.

4.    The edge of the slitting machine blade is not vertical. First, it may be caused by the incorrect angle of the blade holder. Second, it may be because the blade of the slitting machine is not in the center of the knife groove. Third, it is due to the misalignment of the blade edge, which should be replaced in time.
