What is the purpose of the paper cutter? Paper cutter is used to cut the paper before and after printing. The cutter is easy to operate and has no special requirements on the environment. As long as the power is supplied, it can work normally.
After the cutter is used for a long time, some problems will occur more or less, such as the cutter does not move, the abnormal noise, and the paper pusher does not move. This is a recurring problem encountered by printing companies. How to deal with it is not good, which is very unfavorable to printing production. Some users have reported to us that the newly installed paper cutter cuts one knife, and the edge of the knife is broken.
        The choice of the blade sharpening angle of the paper cutter, the quality of the sharpening, and the blade sharpening gap time affect the flatness and smoothness of the cutting edge of the paper. The general blade angle is 19 °. If the cut paper is hard It is necessary to increase the angle of the blade. If you want to improve the quality of the blade, you must ensure that the coolant is sufficient to avoid the edge annealing. Before cutting, you can first sharpen the blade with whetstone, and on the blade Apply soap and paraffin, which can not only improve the sharpness and smoothness of the cutting edge, but also extend the service life of the cutting edge, and the quality of the finished product is better.
        The reason why the cutter will collapse in actual operation is because the operator shortens the sharpening time and the coolant is insufficient, causing the edge of the blade to anneal and narrow the width. The nut must be adjusted during installation to make The blade is cut into the pad blade. If the nut is not adjusted well and the cut is too deep, it will cause chipping.

        This is also a common problem with paper cutters. I hope you will pay attention when using paper cutters.
