Description

Technical Field

[0001] The utility model relates to the technical field of cutting knives, in particular to a cutting knife structure of a carbon fiber cutting machine. Background Art

[0002] Carbon fiber is a new material with excellent performance and is widely used due to its light weight and high tensile strength. During the production process of carbon fiber soft felt or carbon fiber composite materials, it is usually necessary to cut carbon fiber raw materials. The existing cutting knife is a single cutting knife directly clamped on the cutting machine.

[0003] However, in such a structure, when the tool is set to be thinner, it is not only difficult to clamp well, but also easily broken, with a short service life. When the tool is set to be thicker, the tool material is very expensive and the cost is high. At the same time, for a single cutting knife structure, the height of the tool cannot be adjusted. Summary of the Utility Model

[0005] To achieve the above purpose, the utility model provides a cutting knife structure of a carbon fiber cutting machine, including: a tool holder, with one on each of the left and right sides. The two tool holders clamp the tool inside through fastening bolts, for protecting and fixing the tool.

[0006] Adjusting platforms are provided on both of the two tool holders. An adjusting screw rod is installed on one of the adjusting platforms with adjustable height, for adjusting the height of the tool.

[0007] Further, a screw nut is installed on the adjusting platform on the right side, and the adjusting screw rod is installed inside the screw nut with adjustable height through threads.

[0008] A top block is rotatably installed at the bottom of the adjusting screw rod.

[0009] Further, a tool gasket is provided between the tool holder and the tool. The tool gasket is arranged below the adjusting platform, and the tool gasket is detachably installed on the tool holder through countersunk head bolts.

[0010] Further, a segmented tool holder gasket is provided between the two adjusting platforms, and each segment of the tool holder gasket is installed between the tool holders through fastening bolts.

[0011] Further, a semi-circular platform equal in size to the screw nut is provided on the adjusting platform on the left side, and the semi-circular platform covers the screw nut.

[0012] A round hole is provided on the semi-circular platform, and the adjusting screw rod is movably installed in the round hole.

[0013] Furthermore, the tool shim and the tool holder shim are both made of polytetrafluoroethylene.

[0014] The beneficial effects of the present utility model are as follows:

[0015] In the present utility model, a tool holder is provided and clamped around the tool. When the tool is in use, it is not easily broken, improving the service life of the tool. By setting the tool holder, a thinner tool can be used, which can save costs. At the same time, an adjusting screw is provided above the tool, and the height of the tool can be adjusted during use.
