Description

Technical Field

[0001] The utility model relates to the technical field of cutting tool manufacturing equipment, in particular to manufacturing equipment for a blade edge of a sheet-type cutting tool. Background Art

[0002] The most important functional part of knives and scissors is the blade. The edge of the blade refers to the sharpest part of the blade, usually at the front or side of the blade, which can be used to perform tasks such as cutting, chopping or slicing. The edge of the blade needs to be sharpened frequently to maintain its sharpness to ensure the normal use of the blade.

[0003] When performing a knife sharpening operation, the blade of a razor blade or a scissors blade is usually placed against a whetstone at a certain angle, and the blade is moved back and forth, and grinding is achieved through the reciprocating friction between the blade and the whetstone. In order to extend the service life of the tool, it is necessary to retain as much material as possible on the edge while meeting the sharpness requirement of the edge. Therefore, high-quality knife sharpening operations must ensure that the angle of the edge is consistent as much as possible. The utility model author believes that this method of sharpening places high demands on the technical level, proficiency and working status of the sharpener. Especially when facing batch sharpening operations, the fatigue level of the executor will greatly affect the grinding quality of the blade, making the sharpening quality unstable.
