Description

Technical Field

[0001] This utility model relates to the field of blade sharpening technology, specifically a blade double-sided sharpening device. Background Technology

[0002] In daily life, we often need to use various blades. During the production process, blades need to be sharpened using grinding equipment to make them sharp.

[0003] For example, Chinese patent application CN202223405958.8 discloses a blade sharpening device, relating to the field of blade sharpening equipment technology. It includes a housing, a rotating shaft rotatably connected within the housing, and a grinding wheel fixed to one end of the shaft. The grinding wheel is used to sharpen blades. A support frame slides on the upper end of the housing, and a drive device for driving the rotating shaft to rotate is mounted on the support frame. The support frame also includes a stop drive device and a cylinder for the rotating shaft to slide vertically. A removable cover plate is provided on the upper end of the housing, with a groove for the rotating shaft to slide. This application, by using a cover plate, limits the splashing of debris outside the housing, reducing the risk of accidental injury to technicians from debris flying out of the housing, thus improving the safety of using the sharpening equipment.

[0004] However, in actual use, the above-mentioned device grinds the blade with a grinding wheel. During the grinding process, the blade is in a fixed position. As the grinding wheel rotates, the blade cannot move and be ground at the same time. There is a phenomenon that the blade can only be ground in a fixed position. Furthermore, it is not convenient to grind both sides of the blade at the same time, which seriously reduces the grinding effect and quality of the blade and results in poor performance.
