Devillicating grooved roller for carbon fiber production

The utility model relates to a dividing grooved roller for producing carbon fiber, belonging to the device field of the fiber production, which is provided with core shafts, wherein a plurality of round metal sheets which have the same size and smooth surfaces are evenly sleeved on the core shafts, and a round shock insulator is sleeved on the core shaft between the two adjacent metal sheets. The depth and the width of a groove in the utility model can be realized by using shock insulators with different specifications according to the usage requirements, thereby not only reducing the production cost of the grooved roller, but also avoiding the problem of injuring fiber to produce a large amount of broken filaments caused by the poor grooved roller precision, and increasing the quality of products.
