Rapid paper tube processing cutting machine

The invention discloses a rapid paper tube processing cutting machine. The rapid paper tube processing cutting machine comprises a support, telescopic rods and a blade. The telescopic rods are connected with the blade. Rotating shafts are arranged at the two ends of the support respectively. The tail ends of the rotating shafts are fixedly connected with connecting shafts. The connecting shafts are sleeved with rotating columns and guide columns. The rotating columns are connected with the outer circle surfaces of the connecting shafts in a matched manner. The guide columns are connected with the connecting shafts in a matched manner through threads. One end face of each rotating column is matched with the tail end of the corresponding rotating shaft, and the other end face of each rotating column is provided with a thread. The end face, corresponding to the thread face of the corresponding rotating column, of each guide column is provided with a plurality of grooves which are evenly distributed. Sliding blocks are installed in the grooves in a matched manner and provided with gear racks matched with the threads of the rotating columns. Planet gear mechanisms are arranged at the two ends of the support. Each plant gear mechanism comprises a sun gear, plant gears and a gear ring. The sun gears are fixedly connected with the rotating shafts, connecting rods are arranged between the plant gears at corresponding positions, and the telescopic rods are arranged on the connecting rods. The cutting machine improves working efficiency and lowers cost.
