Description

Technical Field

[0001] The invention relates to a slicing device for processing a lining structural core material adhered to the inner cavity wall of a blade into a standard thickness, belonging to the technical field of structural core material slicing. Background Art

[0002] Wind turbine blades are primarily made of fiberglass reinforced plastic (FRP) blades, with the surface wrapped with fiberglass and coated with epoxy resin. The remaining sections are filled with structural core material. The structural core material's primary function in the blade is to reduce blade weight while ensuring stability, allowing the blade to meet required rigidity while increasing wind-catching area. Commonly used structural core materials include balsa wood, PET, PVC, SAN, and HPE. Before injecting the base resin into the laminated FRP blade cavity, a liner is attached to the blade's inner wall. This liner is made by adhering the structural core material to a fiberglass cloth. The liner is then cut into small pieces to align with the blade's inner wall during attachment, but without cutting through the fiberglass cloth.

[0003] The structural core material needs to be cut into sheets of different thicknesses that meet the requirements of the blade design. The square materials of the structural core material are processed into sheets. The cutting equipment currently used is generally flat cutting equipment, which has low efficiency, poor precision, difficult dust discharge, high equipment risk factor, and the saw blade requires greater tension, and has high requirements for the flatness of the mobile platform.
