Description

Technical Field

[0001] This application relates to the technical field of tool grinding, and particularly to a knife grinder. Background Art

[0002] A knife grinder is a device used to trim tools, mostly for trimming metal cutting tools made of high-speed steel. Some are used to trim tools made of cemented carbide and other super-hard materials. There are various types of knife grinders, and their application ranges are also different.

[0003] The knife grinder makes the grinding tool contact the edge of the tool, and repeatedly grinds the edge through the frictional force between the two, thereby sharpening the edge. Since a large amount of heat will be generated during the contact between the grinding tool and the edge, the heat needs to be dissipated, otherwise it will accelerate the loss of the grinding tool and damage the performance of the tool edge.

[0004] In the utility model patent with the authorized publication number: CN209902810U disclosed in the Chinese patent literature, it discloses an "automatic knife grinder", and specifically discloses including: a base, a pillar, a grinding assembly, a positioning assembly and a fixing table. The pillar and the fixing table are both arranged at the upper end of the base. The grinding assembly is installed on the right side of the pillar, and the positioning assembly is arranged on the left side of the fixing table; the structure of the automatic knife grinder is reasonably designed, simple to install, and has strong practicability. The positioning assembly is used to fix the position of the blade to be ground, then the handle is shaken to make the positioning assembly and the grinding assembly approach to a suitable position, and finally the grinding assembly is started to grind the blade to be ground fixed in the positioning assembly. At the same time of grinding, water is introduced through the water outlet pipe to clean and cool the blade to be ground. The automatic knife grinder is worthy of popularization and use in the grinding technology field.

[0005] Generally, a coolant (such as water) is used to cool the grinding tool. When water is sprayed onto the grinding tool for cooling, the water sprayed on the grinding tool will evaporate to form water mist when encountering high temperature. The appearance of a large amount of water mist will affect the vision of the staff, which is not conducive to grinding tools with good performance. Sometimes, work injuries may also occur due to blurred vision; in addition, since the coolant often mixes with dirty oil or other sundries, these sundries mixing into the water mist will further pollute the working environment and the knife grinder. If the staff often inhales the air with such sundries, it will also cause harm to the body.

[0006] The above information disclosed in the above background art section is only used to strengthen the understanding of the background of the present disclosure. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art. Utility Model Content
