Electric Film RollerIt Mainly Consists Of A Motor, Transmission Device, Limit Switch, And Film Winding Shaft. Electric Motors Serve As Power Sources, Converting Electrical Energy Into Mechanical Energy. The Transmission Device Usually Adopts A Gear Set, Which Is Responsible For Converting The High-speed Low Torque Power Output By The Motor Into Low-speed High Torque Power Suitable For Film Rolling, To Ensure A Smooth And Powerful Film Rolling Process. The Limit Switch Plays A Precise Control Role. When The Film Winding Device Reaches The Set Position, The Limit Switch Is Triggered And The Motor Stops Running, Thereby Avoiding Excessive Or Insufficient Film Winding. The Film Winding Shaft Is Connected To The Transmission Device And Directly Responsible For The Winding And Unfolding Of The Film, Achieving The Adjustment Of The Size Of The Ventilation Opening. For Example, In A Common Film Greenhouse, After The Motor Is Started, It Drives The Gear Set To Rotate, Which In Turn Drives The Film Rolling Shaft To Rotate, Rolling Up Or Lowering The Plastic Film Covering The Ventilation Opening, And Flexibly Adjusting The Ventilation Volume, Light Intensity, And Temperature And Humidity Inside The Greenhouse.
Significant Advantage
Efficient And Labor-saving: Compared To Traditional Manual Film Rollers, Electric Film Rollers Greatly Improve Work Efficiency. In Large-scale Commercial Greenhouses, Manual Film Rolling Requires A Lot Of Time And Manpower, While Electric Film Rollers Only Need To Easily Press The Switch To Complete The Rolling And Unwinding Operation Of Large-area Films In A Short Period Of Time. One Person Can Easily Complete The Work Of Multiple People In The Past, Saving A Lot Of Labor And Freeing Growers From Heavy Physical Labor.
Precise Control: The Electric Film Winding Device Can Precisely Control The Stroke And Speed Of The Film Winding According To Actual Needs. By Setting The Limit Switch, The Size Of The Ventilation Opening Can Be Accurately Adjusted, Achieving Precise Regulation Of The Indoor Environment. A Greenhouse For Growing Warm Crops Can Precisely Control The Height Of The Film Rolled Up By The Film Rolling Device When The Temperature Is High, So That The Ventilation Is Just Right, Creating The Most Suitable Growth Environment For Crops And Avoiding Temperature Fluctuations And The Growth Of Pests And Diseases Caused By Improper Ventilation.
Intelligent Linkage: With The Development Of Agricultural Intelligence, Electric Film Rollers Can Be Linked With Intelligent Devices Such As Temperature And Humidity Sensors, Light Sensors, Etc. When The Sensor Detects That The Temperature, Humidity, Or Light Inside The Greenhouse Is Too High, It Will Automatically Send A Signal To The Electric Film Roller To Control Its Start Or Stop, Achieving Automatic Control Of The Greenhouse Environment. In The Hot Summer, When The Temperature Inside The Greenhouse Exceeds The Suitable Growth Temperature For Crops, The Temperature And Humidity Sensor Triggers A Signal, And The Electric Film Rolling Device Automatically Rolls Up The Film To Enhance Ventilation And Heat Dissipation, Maintaining Stable Temperature Inside The Greenhouse.
Key Selection Points
Adaptation To Greenhouse Scale: The Greenhouse Area Is An Important Basis For Choosing An Electric Film Roller. Small Family Style Greenhouses Have A Relatively Small Area And Lower Requirements For The Power Of The Film Roller. Therefore, Electric Film Rollers With Lower Power And Affordable Prices, Such As 60W Or 80W Products, Can Be Selected To Meet The Ventilation And Temperature Regulation Needs Of Small Greenhouses. For Large-scale Commercial Greenhouses, Due To The Large Area And Heavy Weight Of The Film That Needs To Be Rolled, It Is Necessary To Choose Electric Film Rollers With High Power And Strong Torque, Such As 100W Or 130W Models, To Ensure Smooth Rolling And Lowering Of The Film And Ensure The Normal Operation Of The Greenhouse Ventilation System.
Consider Protection Level: The Environment Inside The Greenhouse Is Relatively Humid And May Be Affected By Rain, Dew, And Other Factors. Therefore, It Is Particularly Important To Choose An Electric Film Roller With A Higher Level Of Protection. The Protection Level Is Generally Represented By IP Code, Such As Products With IP55 And Above Levels, Which Can Effectively Prevent Dust From Entering And The Influence Of Water Spray, Ensure Stable Operation Of Electric Film Rollers In Harsh Environments, Extend Equipment Service Life, And Reduce Maintenance Costs In The Later Stage.
