[0026] Working principle: In the existing carbon fiber cloth cutting device, the cloth cannot be fully stretched during the cutting process, resulting in the carbon fiber cloth being prone to relaxation. This relaxation phenomenon not only affects the cutting accuracy and efficiency, but may also cause the edges of the cut carbon fiber cloth to be uneven, or even have burrs or loose edges, affecting its subsequent performance and reducing the quality of product processing. Therefore, in response to the above problems, a carbon fiber cutting device is proposed.

[0027] During the cutting process of the carbon fiber cloth, a large amount of fine fiber dust is generated. In order to prevent the dust from flying everywhere, the fan 32 is used to suck the fine fiber dust generated during the cutting process into the dust collection box 30 through the dust suction port 29. Under the action of the filter plate 34, the fiber impurities in the dust can be intercepted and made to slide to the bottom of the dust collection box 30, and finally discharged through the slag discharge port 35. The gas without fiber impurities will enter the guide box 31 through the filter hole, and finally be purified by the air purifier 33 and discharged from the body. The air purifier 33 model is G-18A, which can effectively absorb and filter the dust, keep the working area clean, and reduce the harm of dust to the environment and personnel.
