Composite fiber tow conveying anti-pollution device

The utility model belongs to the technical field of composite fiber production, particularly relates to a composite fiber tow conveying anti-pollution device, and aims to solve the problem that the processing efficiency is influenced due to poor stability in a polymer fiber conveying process, and adopts the following scheme that the composite fiber tow conveying anti-pollution device comprises a base, the base further comprises a treatment box, and the treatment box is fixed on the side wall of the top end of the base; a mounting plate is fixed to the outer side wall of the treatment box, a driving motor is fixed to the top side wall of the mounting plate, and two symmetrically-distributed rotating shafts are rotationally connected to the inner side wall of the treatment box; when the composite fiber tow shakes in the conveying process, the auxiliary roller is pressed to drive the sliding block to slide in the sliding groove, then the spring is in a compressed state, the enough pressure reduction effect can b
