The present invention discloses a dust collector. The dust collector comprises a base, winding devices respectively fixed at left and right sides of the top face of the base and a leading-in dust collector. Each winding device is formed by a first vertical frame and a second vertical frame which are opposite to each other front and back and fixedly arranged at the top face of the base, the opposite sides of the first vertical frame and the second vertical frame are provided with first sliding slots in an equivalence mode, each first sliding slot is internally provided with a first sliding block, a winding motor is fixedly arranged at the internal portion of the back side of the first vertical frame at the lower portion of the first sliding slot in the first vertical frame, the right side of the winding motor is matchingly connected with a first rotation and winding shaft, the second vertical frame opposite to the winding motor is internally provided with a sliding slot with a mode of run-through arrangement front and back, the inner bottom face of the sliding slot is provided with a guidance connection slot, and a second sliding block is in sliding matching connection with the internal portions of the sliding slot. The dust collector is simple in structure, the mounting and dismounting speed of a winding core is improved, the whole winding process is improved, the automatic control quantification winding work is realized, and the quality of fabrics is improved.
