[0002] In the production process of carbon fiber preforms, cutting and breaking processes may cause small protrusions on the edges of the carbon fiber. If these protrusions are not trimmed, they may affect the overall quality of the carbon fiber preform, especially in situations where high precision and high strength requirements are required;
[0003] In the prior art, when grinding and trimming the edge of a carbon fiber plate, a common practice is to use sandpaper or a polishing wheel; when using a polishing wheel, the polishing wheel will have an effect on the edge of the carbon fiber plate, which may cause the edge corners to disappear, thereby affecting the subsequent splicing performance of the carbon fiber plate; when using sandpaper for grinding, it is necessary to use a sandpaper fixing support to ensure a good contact effect between the sandpaper and the carbon fiber plate to ensure the uniformity and effect of grinding. However, even if a sandpaper fixing support with an internal depression is used, it is still difficult to align the sandpaper with the center of the side of the carbon fiber plate, resulting in the inability to remove the burrs on both sides of the edge of the carbon fiber plate synchronously, affecting the symmetry of the two sides of the edge of the carbon fiber plate;
[0004] Based on the above situation, the polishing wheel will damage the edge corners of the carbon fiber plate, and combined with the use of sandpaper and sandpaper fixing holder, there is a problem of difficulty in aligning with the center of the side of the carbon fiber plate, and the symmetry of both sides of the edge of the carbon fiber plate cannot be guaranteed. Therefore, the present application provides a carbon fiber material cutting edge trimming device. Utility Model Content
