Description

Online knife sharpening device Technical Field The utility model relates to the technical field of cutting bed sharpening, in particular to an online sharpening device. Background When the cloth is cut by the cutting bed, the cutting knife needs to reciprocate relative to the cloth, so that the cutting knife can cut the cloth, in the long-time working process, the cutting knife edge is inevitably worn, the cutting edge becomes blunt, the cutting quality is affected, the cutting knife needs to be polished after a certain period of use, and the conventional common mode is to polish the cloth after the cutting knife is detached, so that the polishing quality can be guaranteed, but the operation is complicated. At present, the utility model patent with the publication number of CN206357002U discloses an automatic sharpening device for a cutting bed, which can drive a motor mounting seat and a sharpening grinding wheel to reciprocate to sharpen a cutting bed tool bit through the expansion and contraction of a cylinder, can also automatically sharpen the cutting bed tool bit through arranging a main control module, has the characteristics of convenience in sharpening, simplicity in operation and high automation degree, and can meet the requirement of automatic sharpening.
