Tail filament fusing device and doffing machine

The utility model provides a tail filament fusing device and a doffing machine, relates to the technical field of chemical fiber filament production, and solves the technical problems that a filament burning mechanism is difficult to contact with tail filaments and the tail filaments are difficult to fuse. The tail wire fusing device comprises a frame, a heating part, a driving mechanism and a moving part, the heating part is fixed to the frame, the driving mechanism is fixed to the frame, is in transmission connection with the moving part and is used for driving the moving part to move on the frame, and when the moving part moves, a tail wire extending into the frame can be downwards pressed to the position making contact with the heating part, so that the tail wire is fused; the tail filament fusing device can be flexibly arranged on the head of the doffing machine or the end of other equipment in butt joint with the doffing machine, so that the occupied space is reduced, the tail filament of the filament s
