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.

The invention discloses a hybrid vehicle engine front-end wheel train control method and device and a storage medium, and the method comprises the steps: collecting a running signal of a hybrid vehicle, and judging the start-stop working condition trend of an engine of the hybrid vehicle according to the running signal; under the condition that the start-stop working condition trend is that shutdown is about to be carried out, shutdown preparation operation is carried out, and the shutdown preparation operation comprises the steps that a front-end wheel train load is removed through an electromagnetic clutch water pump and / or a transmission chain between an engine and a gearbox is tensioned through pre-tightening torque output by a P2 motor; and under the condition that the start-stop working condition trend is about to start, starting auxiliary operation is executed, and the starting auxiliary operation comprises the steps that a signal of a crankshaft position sensor is combined, auxiliary torque is output through a P2 motor to smoothen engine crankshaft rotation, and / or after the engine rotating speed is stable, an electromagnetic clutch water pump is controlled to load a load for a front end gear train. According to the technical scheme, torque impact of starting and stopping of an engine on a front-end wheel train can be reduced from the source, and the problems of vibration and noise of the wheel train are solved.
