This utility model relates to a kind of plane abrasive cloth wheel, especially the reinforced plane abrasive cloth wheel plastic tray. There is a ring slot in the place of abrasive cloth slice. It is the arc transition between the cover cone of the plastic tray and axial vertical surface. There set equally distributed reinforcing rib with ring slot vertically in the place of it. Arc transition bear stress evenly while the rotary strength is higher, dispersing the stress and not easily broken. Meanwhile, the structure also enhances the strength of ring slot and increases greatly rotary strength of plane abrasive cloth wheel, and also makes the cost of plastic tray low. Plane abrasive cloth wheel tray has the advantage of light weight, low cost and high cost performance.
