This manual operation presents the following problems:

[0003] (1) After manually operating a single device to cut the round tube, manual cleaning requires first cleaning the waste at both ends of the round tube, and then using the overhead crane in the factory to lift and tilt the waste deep inside the inner wall of the round tube and shake out the waste that is difficult to handle manually. The manual labor intensity is high and the efficiency is low;

[0004] (2) When manual cleaning is required at both ends of the round tube, the cleanliness of the workpiece cannot be guaranteed, and it is easy to neglect some parts of the cleaning, causing the waste remaining in the round tube to leak onto the back-end equipment, causing damage to the equipment;
