The invention relates to a polyethylene foam material recovery processing method. A workbench, a cutting device and a mincing device are included, wherein the cutting device is arranged on the left side of the workbench; the mincing device is arranged at the right end of the workbench; the cutting device comprises a fixing plate, a first motor, an installing barrel, a stop column, a transmission frame, a transmission plate and a cutting frame; and the mincing device comprises a stacking box, a C-shaped plate, an electric air cylinder, a supporting plate, a segmentation cutter, a push plate frame and a mincing frame. The cutting device is used for cutting foam, the width of the foam is reduced, the mincing device is used for storing and stacking the cut foam, meanwhile, the foam is minced,accordingly, the size of the foam material is reduced, and through screening of the foam, the situation that foam blocks not minced fall down to be collected is avoided.
