The belt sander is widely applicated in the woodbased plate and furniture trade, the requirement is very large. The belt sander have lots of variety and develop fast in recent years. The sander have the characteristic of good adaptability, so it can improve the size precision of the work, take from the surface roughness of the work piece, being one of the important lathes of wood working. More prehensive consideration,so the design content as single double sand on sand in broadband sanding machine design .It has two sand belt shelves which locate on the up part of the sander, feed with track, and have the two kinds of sand shelves. To avoid too big vibrating from the gravity if it was located high, and the electrical engineer drives the roller with leather belt. And the bottom of the anchor bolt holes open have, before the use should be installed on fixed on the floor. This design attaches a good stability.
