The sander is the mechanical equipment used to complete the sanding work. It involves a wide range of industry categories, but the industry generally refers to the sanding machine with automatic feeding system. Sander belt wrinkling: Once the belt is wrinkled, it can no longer be used, generally causing the belt to wrinkle in three possible ways. One is that the sand roller and the tension roller are not parallel in the vertical plane projection, and need to be cushioned and corrected at the center support cylinder. The second is that the sand belt is soft and damp and causes wrinkling. Drying and drying can be used. The third is that the sanding machine does not use the surface of the roller for a long time to become rusted and rough, and the difficulty of swinging the belt triggers the trend. At this time, the roller should be rusted or sanded with a finer sandpaper.
