[0002] Door panel moldings are an important element in home decoration, not only beautifying the interior but also enhancing the overall style and quality of the home. Door panel moldings are cut into the desired shape during production and then polished to remove burrs from their surface. A search revealed prior art (Announcement No.: CN202322706548.5) regarding an EPS decorative molding polishing device. The document describes "an EPS decorative molding polishing device described in the present invention places a slat between a pair of fixed plates. Due to the thickness of the slat, the slat presses against the fixed plates, causing the fixed plates to move to both sides. At this time, the elastic action of a return spring causes the fixed plates to exert a force on the slat, thereby clamping the slat in the middle position. At this time, by pushing the slat forward, the fixed plates, which always remain in the clamped state, guide and limit the slat during movement, making the slat more stable during polishing and adapting to the processing of slats of different thicknesses." However, the fixed plates used for guiding and clamping on both sides in the prior art easily limit the polishing surface of the decorative molding, resulting in poor polishing efficiency.
