Anti-corrosion device for motor winding drum of winch

The invention discloses a winch motor winding drum anti-corrosion device, and relates to the technical field of winch winding drum spraying, the winch motor winding drum anti-corrosion device comprises a supporting table used for supporting a winding drum, an air cylinder is mounted at the bottom of the supporting table, a feeding supporting plate slidably mounted at the bottom of the supporting table is fixed to the telescopic end of the air cylinder, and a lifting frame is vertically slidably mounted on a vertical frame; the sliding frame is provided with a friction rotating assembly used for driving the side blocking disc to rotate. According to the device, the arranged feeding supporting plate reciprocates relative to the supporting table, so that the one-way abutting-pushing assembly can abut against a winding drum to move towards the paint spraying disc, and the effect of orderly feeding of the winding drum is achieved; and rotation driving of the winding drum can be achieved through rotation of a frict
