[0020] like Figs. 1-3 As shown: The system includes a substrate and a sandpaper sheet 8 bonded to the substrate. The substrate is radially divided into an annular support portion 6 and a conical assembly portion 7. The annular support portion 6 is located within the inner circle of the conical assembly portion 7, and an assembly hole 71 is provided in the center of the conical assembly portion 7. The substrate includes a fiberglass layer 1 and a steel paper layer 5. From bottom to top, a cotton-linen cloth layer 2, a metal mesh layer 3, and a protective layer 4 are bonded between the fiberglass layer 1 and the steel paper layer 5. A protective sleeve 41 is provided on the arc surface of the protective layer 4. The fiberglass layer 1, cotton-linen cloth layer 2, and metal mesh layer 3 are all located inside the protective sleeve 41. The protective sleeve 41 is bonded to the outer surface of the fiberglass layer 1, cotton-linen cloth layer 2, and metal mesh layer 3. The bottom surface of the protective sleeve 41 is flush with the bottom surface of the fiberglass layer 1. The metal mesh layer 3 is made of pure copper. The protective layer 4 and the protective sleeve 41 are made of olefin rubber and are integrally formed. The structure, consisting of a fiberglass layer 1, a cotton-linen cloth layer 2, a metal mesh layer 3, a protective layer 4, and a protective sleeve 41, allows the heat generated by friction between the 8 and the workpiece to be conducted sequentially to the fiberglass layer 1, the cotton-linen cloth layer 2, and the metal mesh layer 3. The heat is then conducted through the metal mesh layer 3 to the protective layer 4, which in turn dissipates the heat to the outside. The protective sleeve 41 absorbs heat from the edges of the fiberglass layer 1, the cotton-linen cloth layer 2, and the metal mesh layer 3, and then dissipates it to the outside. Simultaneously, the protective sleeve 41 protects the fiberglass layer 1, absorbing the impact force when it collides with external objects, thus improving the heat dissipation efficiency of the flapper. Furthermore, the protection of the fiberglass layer 1 extends the service life of the flapper. The multi-layered structure, primarily composed of flexible materials, provides the base with toughness and elasticity, resulting in better operational performance.
