Screw conveyor tensioning device

The normal operation of belt conveyor must make the conveyor belt have a certain tension, and the equipment that provides tension is the tensioning device. Tension device refers to the device that generates the pre-tension of the traction parts of the conveyor to ensure its normal operation. It is a device to adjust the tension of conveyor belt and generate the tension required for friction drive, and it is an essential part of belt conveyor. The general conveyor tensioning device has the following functions: (1) Make the conveyor belt have enough tension to ensure that sufficient driving force can be generated between the conveyor belt and the driving roller to prevent slipping; (2) ensure that the tension of each point of the conveyor belt is not lower than a given value, so as to prevent the conveyor belt from spreading and increasing the running resistance due to excessive relaxation between idlers; (3) Compensate the elastic and plastic deformation of the conveyor belt (4) Provid…
