Reel-to-reel hot roller coining forming method for micro-nano structure on surface of polymer

The invention relates to a reel-to-reel hot roller coining forming method for a micro-nano structure on the surface of polymer. The reel-to-reel hot roller coining forming method comprises the steps that a polymer material is conveyed to a preheat roller from an unreeling device, preheated to the attaching temperature and attached to a base band in a hot pressing mode; the polymer material attached to the base band is conveyed to the position between a mold roller and a pressure roller and heated to the coining temperature through the mold roller heated in advance, and then a mold cavity is filled with the polymer material through the action of the pressure roller; mold filling and supersonic vibration assembly starting are conducted at the same time, and the reel-to-reel hot roller coining process is completed with assistance of supersonic vibration; the polymer material is conveyed out from the position between the mold roller and the pressure roller, and then cooled and separated from the position inside the mold roller; and after demolding is completed, a polymer product is continuously cooled, separation of the polymer product and the base band is achieved, and finally reeling is conducted. According to the reel-to-reel hot roller coining forming method for the micro-nano structure on the surface of the polymer, the reel-to-reel hot roller coining process is improved through supersonic vibration, the mold filling process is accelerated, the duplication precision is improved, and the demolding force and demolding deformation are reduced; and the reel-to-reel hot roller coining forming method is advanced.
