Description

Technical Field

[0001] The present invention relates to the technical field of knife sharpness detection, and in particular to a food knife sharpness detection device. Background Art

[0002] The sharpness of food knife directly affects the efficiency and quality of food processing. After the food knife is manufactured, it is usually necessary to detect its sharpness. For example, in the patent with application number: 202322368386.9, a tool sharpness detection mechanism is disclosed, including a workbench and a side plate, the outer wall of the workbench is connected with a slide rail, the interior of the slide rail is provided with a sliding block, the interior of the sliding block is provided with a sliding groove, the interior of the sliding groove is connected with a bidirectional screw rod, and one end of the bidirectional screw rod is connected with a motor. The tool sharpness detection mechanism, through the setting of the bidirectional screw rod and the sliding block, when it is necessary to detect the sharpness of its tool, it only needs to turn on the motor, so that the motor drives the bidirectional screw rod to rotate, and thereby drives its clamp to slide in the opposite or reverse direction inside the sliding groove, so that it adjusts the spacing of the clamp to adapt to tools of different lengths and sizes, and when it is adjusted to a suitable position, the reciprocating motor is turned on again, so that the tool reciprocates to cut the object placed in its storage slot, thereby different from the traditional type of manual testing, thereby relatively reducing its safety hazards.

[0003] Traditionally, tool sharpness testing relies mainly on worker experience or simple cutting tests to determine tool sharpness. However, only a single tool can be tested at a time. Furthermore, when the tool is tested by a mechanism, after the first test, a test edge will be left on the test object. Therefore, manual movement and adjustment are required for the second test, which is troublesome. Summary of the invention
