The anti-skid pulley of the utility model can push the cargo forward without damaging the packaging belt / rope and the cargo; compared with the prior art design of adding anti-skid grooves or anti-skid corrugations to the outer surface of the roller sleeve, the anti-skid pulley of the utility model reduces the contact area between the concave and convex positions and the packaging belt / rope, and the gap in the concave position will not get stuck with the packaging belt / rope, and can also increase the friction between the roller and the cargo, thereby avoiding the situation of getting stuck and slipping between the packaging belt / rope and the roller.
