As a conveyor belt manufacturers say on some common-sense knowledge should be understood that the following strength conveyor belt factory to you elaborate on the type of belt tensioning device, you do not know much about it, here look at it together.
         A spiral tensioning device
         Spiral tensioning device structure is simple, taut stroke is too small, only suitable for short-distance conveyor, generally less than 80m when the captain selection. Drawback is that when the tape stretch yourself, you can not automatically taut.
         2 Gravity tensioning device
         Gravity tensioning device is the simplest structure, is the most widely used as a tensioning device which is to use the hammer to automatically taut. Because weight by weight taut. So that it can ensure tensioning remains constant under various conditions. Can automatically compensate for the elongation of the tape. Gravity tensioning device has the advantage of safety and high reliability. Disadvantage is that you can not adjust the tension of the space require large in space restricted areas, can not be used.
         3 Fixed winch tensioning device
         Fixed winch tensioning device is the use of a small winch to tighten. Winch is generally used to worm gear reducer drive reel winding rope to tighten the tape.
         4 automatic tensioning device
Automatic tensioning device can not only according to the traction drive rollers to automatically adjust tension force. But also to compensate for the elongation of the tape.
