| Belt conveyor tensioning device of the main effect is taut conveyor belt,to ensure the normal operation of conveyor,when starting and braking,the minimum tension and avoid conveyor belt and driving roller slip,to prevent the conveyor belt sag between the supporting roller group more than allowed.In recent years,with the belt conveyor towards long distance,high speed operation,more driven,high-power direction,belt conveyor in running in the process of instability,variability on the use of belt conveyor and the economic benefit of the whole system has a lot of influence,Especially in conveyor starting and braking of this phase,the tension of conveyor and normal operation,the change of value is very large,the specific performance for the adhesive tape fracture,mechanical damage,local resonance jump and fold belt and material,vibration and so on the serious influence the service life of belt conveyor and belt.The ordinary tension system,tension in the conveying system fixed,unable to solve the above problem.So,studying a tensioning force needed to follow the conveyor belt tension automatically adjust tension device,for the dynamic design of belt conveyor is very be necessary.In order to inhibit the spread of harmful of tensile wave,in this paper,through theoretical analysis of the tension in the belt conveyor under different working conditions and capacity required tension;And tensioning device are analyzed through practical experience the relationship between the mechanical,hydraulic,control,and then adopts Siemens PLC products as well as the application of PID control and fuzzy control design for a belt conveyor hydraulic tensioning adaptive control device.The device can detect real-time need the tension of belt conveyor and can automatically adjust the belt tension and ensure the safety of the belt conveyor running smoothly,saving energy and reducing consumption,to ensure production,effectively extending the serv ice life of the adhesive tape machine,can also be optimized selection of belt safety factor,save equipment investment... |
