Description

Technical Field

[0001] The utility model relates to the technical field of knife sharpening machines, in particular to a full-automatic knife sharpening machine. Background Art

[0002] The existing full-automatic knife sharpening machine is composed of a fixture and a knife sharpening assembly. However, when it is in use, it does not have the functions of double-sided simultaneous grinding and single-sided selective grinding. This means that this type of knife sharpening machine can only adopt a single processing method, lacking flexibility and being unable to adapt to different processing requirements and diverse application scenarios. If both sides cannot be ground simultaneously, the two sides of the tool need to be ground separately, which will lead to an extended processing time, reduced production efficiency, and the inability to fine-tune the knife sharpening assembly, making it difficult to ensure the best contact angle and pressure between the knife sharpening assembly and the tool, and possibly resulting in an unsatisfactory grinding effect. Summary of the Utility Model

[0003] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a full-automatic knife sharpening machine. By using two electric push rods to respectively push a grinding belt close to the tool, the two sides of the tool can be ground simultaneously, and either side can be arbitrarily selected for grinding. Grinding both sides of the tool simultaneously can reduce the processing time and improve production efficiency. Unilateral grinding can be selected according to needs, enabling flexible adaptation to different processing requirements. Moreover, the electric push rod three can drive the sliding plate to move, so that the positions of the two grinding belts can be translated and finely adjusted, achieving precise control of the positions of the grinding belts. This precise adjustment can ensure the best contact angle and pressure during the grinding process, thereby improving the grinding effect and the quality of the tool.
