Glass fiber filament separating device

The invention discloses a glass fiber filament dividing device, and belongs to the technical field of glass fiber manufacturing, the glass fiber filament dividing device comprises a base rod, a filament dividing block and a lining part, the filament dividing block is installed on the base rod, a filament dividing hole is formed in the filament dividing block, the lining part is hollow and is used for allowing a fiber bundle to pass through, the lining part comprises two half frames which are oppositely combined together, and the half frames are arranged on the base rod. The two half frames are rotationally arranged in the filament separating holes and can rotate relatively, a plurality of abutting blocks used for abutting against the inner walls of the filament separating holes are distributed on the outer side face of the lining part in the circumferential direction, and in the using process, fiber bundles of glass fibers can penetrate through the lining part on the filament separating blocks, so that the fi
