Abstract
A sand belt-tensioning device includes a drive roller, a fixing member, a pulling member, and a resilient member. A sand belt is wound around a roller body of the drive roller. The drive roller has opposite first and second end surfaces that are formed respectively with axially extending first and second rotating shafts. The fixing member is sleeved fixedly on the first rotating shaft, and is connected fixedly to an end of the sand belt. The pulling member is sleeved rotatably on the second rotating shaft, and is connected fixedly to the other end of the sand belt at an eccentric position. The resilient member biases the pulling member to rotate about the second rotating shaft in a direction so as to tauten the sand belt on the drive roller.
