[0002] The cutting knife is a kind of knife mainly arranged on the cutting bed and used for cutting various kinds of cloth, and the cutting frequency of the cutting knife is generally fast when cutting the cloth, so that the high-speed movement of the cutting knife in the cutting process can easily cause the temperature of the surface of the cutting knife to rise rapidly, so that the cut cloth is damaged due to the high temperature, and the wear of the cutting knife is also accelerated.

[0003] Especially when cutting the cloth with glue, the cutting knife will generate a large amount of heat due to high-speed friction with the cut cloth, thereby causing the glue cloth to melt due to heat, and even causing the upper and lower layers of cloth to be adhered to each other, affecting the cutting quality of the cutting knife, and the surface temperature of the cutting knife is too high, which can cause the cutting knife to be tempered, thereby reducing the hardness and service life of the cutting knife.

[0035] And the cutting knife 1 is located at a section of the cutting edge 12, that is, the section of the cutting knife 1 cuts into the cloth 4 and extends into the cutting bed, and the cutting knife 1 at this section cannot be effectively cooled by the cooling medium or other heat dissipation methods when cutting the cloth 4, because it is mostly located below the cloth 4, so that the temperature of the cutting knife 1 at this section is easily accumulated and increased.

[0036] In order to improve the cooling and heat dissipation effect of the cutting knife 1 at the section of the cutting edge 12, a heat dissipation groove 14 is formed on the blade back 13 and extends to below the cloth 4 along the length direction of the cutting knife 1, the heat dissipation groove 14 extends to the inside of the cutting knife 1 and penetrates the blade back 13 outward, and the heat dissipation groove 14 can increase the heat dissipation area of the cutting knife 1 as a whole and improve the overall heat dissipation effect of the cutting knife 1.

[0037] And a spray head 3 is arranged on one side of the cutting knife 1, the spray head 3 is arranged corresponding to the heat dissipation groove 14 and is used for conveying the cooling medium into the heat dissipation groove 14, and the spray head 3 is provided with spray holes 31 parallel to the heat dissipation groove 14, so that the cooling medium for heat absorption can be conveyed into the heat dissipation groove 14 through the spray holes 31.
