Electric Film RollerIt Is An Important Accessory Used For Rolling Plastic Film And Opening And Closing Ventilation Openings In Greenhouses. Here Is A Detailed Introduction:
Working Principle
Electric Film Rollers Are Usually Equipped With A Reduction Motor At The End Of The Film Winding Shaft, Which Drives The Rotation Of The Film Winding Shaft To Open Or Close The Ventilation Opening. The Forward And Reverse Rotation Of The Motor Controls The Rolling And Lowering Of The Film, And The Stroke Of The Film Winding Shaft Is Controlled By A Limit Switch To Prevent Over Rolling.
Structural Composition
Motor: Generally, Low-power DC Motors Are Used, But There Are Also AC Motors That Require Distribution Equipment Such As Rectifiers.
Deceleration Mechanism: Converts The High Speed Of The Motor Into The Low Speed Required By The Film Winding Shaft To Provide Sufficient Torque To Drive The Film Winding And Unwinding.
Limit Switch: Including Upper Limit Device And Lower Limit Device, Installed On The Upper And Lower Edges Of The Ventilation Port. When The Film Winding Shaft Encounters The Limit Switch During Operation, It Automatically Cuts Off The Power And Stops The Rotation Of The Film Winding Shaft.
Roll Film Shaft: Usually Made Of Galvanized Pipe Or Other Materials, Used For Wrapping Plastic Film, And Its Length Depends On The Size Of The Greenhouse.
Swing Arm: Used To Control The Running Trajectory Of The Film Rolling Shaft, It Can Be Divided Into Free Arm And Fixed Arm. Fixed Arm Can Be Further Divided Into Wall Fixed Arm And Ground Fixed Arm, And Its End Is Generally Equipped With A Rotatable Shaft.
Feature And Advantage
High Degree Of Automation: It Can Achieve Electric Control, Without The Need For Manual Film Rolling, Saving Manpower And Improving Work Efficiency.
Stable Operation: It Has An Output Self-locking Function, High Torque, And Can Smoothly Roll Up And Put Down The Film Without Easily Experiencing Jamming.
High Adjustment Accuracy: The Stroke Adjustment Is Accurate, And The Opening Size Of The Ventilation Port Can Be Precisely Controlled According To The Needs, Making It Easy To Achieve Precise Control Of The Greenhouse Environment.
Strong Adaptability: It Has Functions Such As Rain Proof And Anti Condensation, Suitable For Different Climatic Conditions, And Can Work Normally In Humid, Rainy And Other Environments.
Main Parameters
Power: Common Types Include 60W, 80W, 100W, 130W, Etc. The Power Size Should Be Selected According To The Length Of The Greenhouse And The Weight Of The Film.
Voltage: There Are DC24V, AC220V, Etc. DC24V Is More Commonly Used And Has Higher Safety.
Torque: Different Models Of Electric Film Rollers Have Different Torques. For Example, A 100W Motor May Have A Torque Of 100N · M, And The Greater The Torque, The Stronger The Ability To Drive The Film.
Maximum Film Winding Length: Generally Related To Power, Such As 60W Electric Film Winding Machine Suitable For Winding 60 Meter Long Films, 80W Suitable For Winding 80 Meter Long Films, Etc.
Installation And Maintenance
Installation: The Installation Method Is Similar To That Of A Manual Film Roller. According To The Structure And Size Of The Greenhouse, The Electric Film Roller Should Be Correctly Installed At The End Of The Film Roller Shaft, And The Power Supply And Limit Switch Should Be Connected.
Maintenance: Regularly Clean The Equipment, Check Whether The Wires Are Damaged, Whether The Limit Switches Are Working Properly, Whether The Connections Of Various Components Are Loose, Etc., To Ensure The Normal Operation And Service Life Of The Equipment.
