Description

Technical Field

[0001] This utility model belongs to the field of composite material molding technology, and specifically relates to a slitting device for unidirectional composite material prepreg filament bundles. Background Technology

[0002] Unidirectional prepreg composite fiber bundles are an intermediate form of high-performance composite materials, widely used in aerospace, automotive, and wind turbine blade industries. Their core characteristic is the highly ordered arrangement of fibers along a single direction, pre-impregnated with resin (thermosetting or thermoplastic). Unidirectional prepreg composite fiber bundles require different slitting operations via a slitting structure. However, most common slitting devices have fixed slitting blades, making it difficult to adapt to different specifications (such as width and fiber density) of prepreg slitting requirements. The blade position cannot be adjusted according to actual slitting needs, and since the slitting blade is a consumable part, wear on the blade tip affects the quality of the slitting. Furthermore, the inconvenience of easily disassembling and assembling the slitting blade also impacts the slitting operation.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
