[0002] Carbon fiber has the characteristics of high strength, high stiffness, light weight, high temperature resistance, corrosion resistance, excellent electrical properties, and strong compression and bending resistance, and has always maintained a dominant position in reinforced composite materials. In the production process of carbon fiber products, carbon fiber filaments need to be cut and then produced.

[0003] The existing cutting method is to continuously feed carbon fiber filaments and then press down the cutter to cut.

[0008] Furthermore, a slider is provided on the adjustable bearing seat, and a slide rail is provided on the adjustment bracket. The adjustable bearing seat cooperates with the slide rail through the slider and is movably installed on the adjustment bracket. An adjusting screw is rotatably installed on the adjustable bearing seat, and the adjusting screw installs the adjustable bearing seat on the adjustment bracket through a thread so that the height of the adjustable bearing seat can be adjusted.

[0009] Furthermore, both ends of the cutter are rotatably mounted on a fixed bearing seat via cutter bearings.

[0010] Furthermore, both sides of the pressure roller are rotatably mounted in an adjustable bearing seat through pressure roller bearings.

[0011] Furthermore, a driver is installed at either end of the cutter.

[0013] In the utility model, the cutter is cylindrical, and blades are arranged at equal angular intervals on the periphery of the cylinder. The carbon fiber filaments are introduced into the cutting machine, and the carbon fiber filaments are overlapped on the blades and are continuously wound. When the winding reaches a certain thickness, the carbon fiber filaments will be squeezed and then cut off.
