[0037] Specifically, the dust removal box 1 is fixedly installed between two conveying devices for the woolen toy production line. The conveying device is an existing known technology. The conveying device conveys the produced woolen toys. The woolen toys are conveyed to the dust removal box 1, and a plurality of conveying rollers 2 are driven to rotate by the driving unit 7. The side of the conveying roller 2 is provided with a convex strip 3. The convex strip 3 makes the woolen toys bump up and down in the dust removal box 1, and the dust on the surface of the woolen toys is released to float in the dust removal box 1. At the same time, the negative voltage is connected to the discharge electrode plate 5, and the air molecules between the discharge electrode plate 5 and the dust collecting electrode plate 6 will be ionized into positive ions and electrons. In the process of rushing to the dust collecting electrode plate 6, the electrons will encounter dust particles in the airflow. After the electrons combine with the dust particles, the dust particles will be negatively charged. The dust with charge rushes to the positive dust collecting plate 6. The dust collecting plate 6 adsorbs the dust, and the woolen toys are dusted during transportation, thereby improving the efficiency of the woolen toy production line in dust removal of woolen toys. At the same time, the dust scraping unit 4 is turned on regularly or manually, and the dust scraping unit 4 scrapes the dust adsorbed on the dust collecting plate 6 into the dust collecting trough 8, and the dust in the dust collecting trough 8 is pushed out by turning on the dust pushing unit 9, thereby achieving the effect of automatically cleaning the dust.
