The role of the belt conveyor tensioning device: to ensure that the conveyor belt is tightly attached to the driving drum, so that the winding end of the ratchet strap manufacturer has enough tension so that the required traction can be transmitted, and the required traction is generated between the roller and the tape. Friction to prevent the conveyor belt from slipping. Limit the tension at each point of the conveyor belt to not less than a certain value to prevent excessive slack and sagging of the belt between the supporting rollers, causing bulk materials and increasing movement resistance, so that the conveyor can work normally. Compensate for the plastic elongation of the conveyor belt due to tension and the change of elastic elongation under transitional conditions. Provide the necessary itinerary for the conveyor belt to return to the street.
The type of belt conveyor tensioning device: In general, the types of ratchet tie-down strap include screw type, cart type, vertical type, hydraulic tensioning and hoisting winch, etc. In order to make the drive roller give enough tension to the belt, to ensure that the conveyor belt does not slip on the drive roller, and the conveyor belt does not sag between two adjacent rollers, it is necessary to apply an initial tension to the conveyor belt. Tension is obtained by tensioning the conveyor belt by the tensioning device of the conveyor. Within the design range, the greater the initial tension, the greater the friction between the belt and the drive drum.
