[0002] At present, China's wind turbine blade market has formed diversified main investment forms such as foreign-funded enterprises, private enterprises, research institutes, and listed companies. Foreign-funded enterprises mainly include GE, LM, GAMESA, and VESTAS, while domestic enterprises are represented by Times New Materials, Sinoma Technology, AVIC Huiteng, and Zhongfu Lianzhong. When processing wind turbine blades, it is necessary to cut the flash on their surface.

[0003] A wind turbine blade flash cutting device with a Chinese authorized announcement number of CN210678869U, which drives the pressure plate to move through the electric hydraulic cylinder installed at the bottom of the U-shaped frame, is convenient for limiting and fixing the wind turbine blades that need to cut flash, avoiding shaking of the wind turbine blades during the cutting process, which may cause damage to the wind turbine blades. The threaded rod is driven to rotate by the installed stepper motor, and the connection block is driven to reciprocate on the surface of the threaded rod through the rotation of the threaded rod. The fixed block is driven to move through the connecting block, which facilitates the cutting of flash through the rotating wheel.

[0004] There are still certain shortcomings in use. When cutting the flash edge of the blade, debris will fly. When the debris flies to the human body surface, it will cause damage to the human body, reducing the safety of the cutting equipment when in use. At the same time, the temperature of the contact part between the blade and the blade rises sharply during cutting. If the blade and the blade cannot be cooled in time, the surface temperature of the blade will be high and it will be easy to be damaged, which limits the practicality of the cutting equipment.
