The application relates to a conveying roller and a filter rod receiving device, the conveying roller comprising a roller body and end covers, the roller body extending along a first direction, the roller body being provided with a cavity penetrating through the roller body along the first direction; the two end covers being respectively located at two ends of the roller body in the first direction and being detachably connected with the roller body, the end cover comprising a cover body and a rotating shaft, the cover body being connected with the roller body, the rotating shaft being located at a side of the cover body away from the roller body, and at least one of the rotating shafts of the two end covers being used for bearing a bearing. The conveying roller provided by the application is provided with the cavity penetrating through the roller body, so that the overall weight of the conveying roller is reduced, the torque impact on the rotating shaft is reduced, the probability of the rotating shaft being broken is reduced, and the service life of the conveying roller is prolonged. The roller body and the end cover are detachably connected, so that even if the rotating shaft on the end cover is broken, the roller body can still be used by replacing the end cover, the replacement efficiency is improved, and the maintenance cost is reduced.
