During the use of the paper cutter, sometimes "cutting knife" failure occurs, which seriously affects the normal work of the paper cutter. If you want to eliminate this problem fundamentally, you must start with improving the structure of the cutting system of the paper cutter. This is not something that ordinary users can do. For ordinary users, you want to eliminate or reduce "Knife" failure should pay attention to the following aspects:
        1. Sharpen the blade in time to keep the blade sharp. In addition, if not necessary, try not to use blades with large corners. This can effectively reduce the cutting resistance of the paper.
        2. Pay attention to the change of the slide gap. When the phenomenon of "cutting the knife" becomes obvious, you should first check the change of the slide gap. Under normal circumstances, the gap should not exceed 0.1 mm. The sliding surface is subjected to a large load during the cutting process, coupled with poor lubrication conditions, and is constantly worn during use, causing the gap to increase, which causes a “cut out” failure. When the confirmation gap exceeds the allowable value, it should be adjusted in time.

        3. Careful maintenance to ensure good lubrication of the slide surface.
