The use of paper cutters provides higher cutting accuracy for the printing industry and packaging industry. Currently, various types of high-end paper cutters such as automatic paper cutters, numerical control paper cutters and program-controlled paper cutters are widely used in related industries. Among them, the cutter blade is one of the important parts of the cutter, and its sharpness and service life largely influence the production efficiency of the cutter. Then, what are the main factors affecting the use of paper cutter blades and their longevity?
First, the knife material. The cutter of a single piece cutter is made of high-temperature insert welding of the cutting edge and the cutter body. The cutting edge is made of high hardness chromium-tungsten-manganese steel and the cutter body is made of low-carbon steel. The durability of the cutter is directly proportional to the hardness of the steel part of the cutting edge. The high-quality insert can reach a hardness of HR55~60 after quenching.
Second, the cutter shape and angle of the knife. On a single-sided paper cutter, a single sharpening tool is generally used with a sharpening angle between 19° and 23°. However, this type of sharpened edge allows the bevel face of the tool to withstand the pressure from the cut away portion of the paper stack during the cutting process. Under the rubbing of the paper edge, the bevel of the blade is quickly worn. Double-edged cutting tools have obvious advantages, and their sharpening helps to reduce the load on the machine and improve the accuracy of cutting. Therefore, under the precondition that the tool material allows and considering the cutting force of the cutting material, the sharpening angle should be as small as possible.
Third, the quality of the paper cutter sharpening. The higher the quality of the sharpening knife, the longer the service life of the cutter and the better the cutting quality.
Fourth, the type of cutting material. During the cutting process, the blunt speed of the cutter edge is related to the wear resistance of the cut material. When cutting the paper, the speed at which the blades become blunt is related to the hardness and hardness of the paper and the amount of ash content. The harder the blade and the higher the ash content, the faster the blades become blunt.
The above factors affect the use effect and the service life of the cutter blades. Therefore, in the use of various types of high-end paper cutters such as automatic paper cutters, numerical control paper cutters, and program-controlled paper cutters, attention should be paid to the use of the paper cutter blades. The use efficiency and service life.
