Winding guide assembly, filament collecting device and carbon fiber precursor packaging part

The invention belongs to the technical field of carbon fiber precursor production, and discloses a winding guide assembly, a filament collecting device and a carbon fiber precursor packaging piece, the edge of the winding guide assembly is provided with at least two filament bundle guide grooves which are formed by sinking towards the inner side of the edge, and the filament bundle guide grooves are arranged at intervals; the wire collecting device comprises the winding guide assembly. The winding guide assembly can be applied to the filament winding device, two or more filament bundles can be wound on one winding drum side by side at the same time, the winding and filament winding efficiency is improved, meanwhile, winding and filament winding of the two or more filament bundles can be completed at the same time through one winding shaft of the filament winding device, and the winding efficiency is improved. And in the subsequent steps of pre-oxidation, carbonization and the like of the protofilament, two or
