A method for using a rotary sharpening device for bamboo processing, characterized in that: The following steps are involved: Step 1: Before sharpening the end of the bamboo, the operator first soaks the end of the bamboo in hot water, and then inserts the soaked end of the bamboo into the inner cavity of the first guide frame (66), passes through the first guide frame (66) and enters the inner cavity of the second guide frame (86); Step 2: After placing the bamboo, rotate the first threaded rod (610) until the second threaded rod (611) is no longer threadedly connected to the inner wall of the first threaded ring (67), and then rotate the rotating sleeve (64) so that the axis of the first guide frame (66) is no longer aligned with the axis of the second guide frame (86); Step 3: After adjusting the bending angle of the bamboo, rotate the first threaded rod (610) in the opposite direction until the second threaded rod (611) completely enters the inner cavity of the first threaded ring (67). Then, connect the exhaust fan (84) to the power supply and turn on the exhaust fan (84). After the exhaust fan (84) starts working, it will generate airflow in the ash outlet pipe (83) and the inner cavity of the protective box (75). Then, a collection bag is placed at the air outlet of the ash outlet pipe (83); Step 4: After the preparation work is completed, the servo motor (71) is connected to the power supply and the switch of the servo motor (71) is turned on. The servo motor (71) starts to work, and the rotating rod (77) drives the sharpening block (79) to start rotating and sharpen the end of the bamboo under the rotation of the servo motor (71); Step 5: After the bamboo is sharpened, turn off the exhaust fan (84) and the servo motor (71), and remove the collection bag at the end of the ash outlet pipe (83). Then repeat the previous operation again so that the axis of the first guide frame (66) and the axis of the second guide frame (86) are in a straight line, and the bamboo can be removed.
