Device for repairing bobbin

The invention discloses a device for repairing a bobbin. The device comprises a lower base, and a power device is arranged in the lower base. A plurality of abrasive wheels are arranged on the lower base; vertical guide rails are arranged on the two sides of the lower base, and an upper base is arranged between the two guide rails; sleeve rings are arranged on the two sides of the upper base, and are in interference fit with the guide rails; the upper base is in sliding connection with the guide rails through the sleeve rings and can vertically slide along the guide rails; a plurality of abrasive wheels are arranged on the bottom face of the upper base, and the abrasive wheels of the upper base correspond to the abrasive wheels of the lower base in position; a power device is arranged in the upper base, and the abrasive wheels are in transmission connection with the power device of the base through transmission shafts; the abrasive wheels are rotating bodies, and rotating shafts of the abrasive wheels coincide with axes of the transmission shafts; a bobbin seat capable of being taken down is arranged on the lower base, and a plurality of bobbin grooves are formed in the bobbin seat; the number of the bobbin grooves is equal to the number of the abrasive wheels on the lower base, and the positions of the bobbin grooves in the bobbin seat correspond to the positions of the abrasive wheels on the lower base; and the bobbin can be rapidly repaired, the production cost is reduced, and meanwhile the environment is protected.
