Technical Field

[0001] The utility model relates to a cutting device, in particular to a wind turbine blade flash cutting device and a dust removal mechanism thereof. Background Art

[0002] When manufacturing wind turbine blades, the upper shell and the lower shell of the blade need to be bonded together in a mold. After the mold is solidified, the part of the bonding point that exceeds the blade contour (i.e., the flash) needs to be cut so that the blade can finally meet the standard contour requirements.
