Paper cutting machines are currently a relatively large type of mechanical equipment. Whether in terms of volume or technological content, they are widely used in the market. In fact, after years of development, the production technology of paper cutting machines has become very mature. In this article, the author mainly analyzes the factors that affect the service life of paper cutting machine blades. You can learn about:

1. The quality of the paper cutter sharpening knife. The higher the quality, the longer the service life of the cutting tool, resulting in better quality crops.

2. The shape and angle of the blade grinding. Single sided paper cutting machines generally use a single grinding knife with a grinding angle of 19 ° to 23 °. Sharpening such a shape results in the pressure that the tool on the inclined surface bears during the cutting process, which is cut open from the part of the paper stack. The paper base friction in one section quickly wears out the inclined surface of the blade. The cutting edge of double-sided cutting tools has obvious advantages, which helps to reduce the load on the machine and improve the accuracy of crop sharpening. Therefore, in the case of tool materials, the sharpening angle should be as small as possible, taking into account the size of crop shear resistance.

3. The material of the knife. The single piece cutting machine tool is made by inlaying and welding the blade and blade body at high temperatures. The chromium tungsten manganese steel blade has high hardness and low-carbon steel blade body. The hardness of the tool steel at the edge of the durability is directly proportional to the quality of the blade, and the hardness of the blade is as high as 60 quenched HR55.

4. Different crop materials. The speed at which the edges of the cutter become blunt and the wear resistance of the material during the cutting process. When cutting paper, the speed at which the blade becomes dull depends on the softness, hardness, and ash content of the paper. The cutting operation has a harder hand feel, and the higher the ash content of the paper, the faster the speed and the dullness of the blades.
