The invention belongs to the field of piano assembly and relates to a piano key wool pasting machine applied to a wool pasting process for bushing wool made of a hot-molten adhesive film. The piano key wool pasting machine comprises feeding mechanisms, a pressing and hot-melting mechanism and a cutter, wherein the pressing and hot-melting mechanism is vertically installed; the feeding mechanisms are vertically installed and are symmetrically distributed on the two sides of the pressing and hot-melting mechanism corresponding to the two sides walls of an upper hand hole and a lower hand hole, and used for vertically conveying bushing wool; and the cutter is installed at the pressing-in end of the pressing and hot-melting mechanism for cutting the bushing wool. The bushing wool is pressed onthe two side walls of the upper hand hole and the lower hand hole through hot-pressing heads, the hot-molten adhesive film is heated and molten, and therefore the wool pasting work is completed.
