In The Current Era Of Rapid Development In Modern Agriculture And Greenhouse Cultivation, Manual Regulation Of Greenhouse Environments Is No Longer Sufficient To Meet The Demands Of Large-scale And Refined Production.Electric Film RollerAs A New Type Of Equipment That Replaces Traditional Manual Film Rollers, With Its Automated Operation And Stable Performance, It Has Become The Core Equipment For Greenhouse Ventilation, Temperature Control, And Lighting Regulation, Profoundly Changing The Mode Of Greenhouse Management And Providing Strong Support For Improving The Quality And Efficiency Of Agricultural Production. Below Is A Detailed Introduction To This Device For You.
Core Definition And Working Principle
Electric Film Rolling Machine Is An Automated Device That Uses A Motor To Roll And Release Greenhouse Films. It Is Mainly Used For Opening And Closing The Side And Top Windows Of Plastic Film Greenhouses. Its Working Principle Is Not Complicated. It Is Powered By A Motor And Driven By An Internal Gear Transmission Mechanism To Rotate The Film Winding Shaft. When The Motor Rotates Forward, The Film Winding Shaft Rotates Clockwise To Complete The Film Winding Action, And When It Rotates Backward, It Rotates Counterclockwise To Achieve Film Release; Paired With A Control System, The Film Winding Stroke Can Be Accurately Controlled. Some High-end Models Also Adjust The Rotation Direction And Efficiency Through The Main Control Chip, And Cooperate With Relays To Achieve Forward And Reverse Control. The Capacitor Component Plays A Role In Leakage And Overload Protection, Ensuring Stable Operation Of The Equipment. Meanwhile, Most Products Will Undergo Overall Waterproof Treatment On The Control Board, Which Can Adapt To Harsh Outdoor Environments Such As Rain And Snow.
Core Structure And Mainstream Types
Core Structure: Its Core Components Include Motors, Reducers, Film Rolling Shafts, Control Systems, Etc. As A Power Source, The Motor Has Various Power Options Ranging From 40W To 150W; The Reducer Is Made Of Gear Steel Material And Refined Through Heat Treatment To Ensure Transmission Efficiency And Service Life; Thin Walled Galvanized Pipes With A Diameter Of 25 * 1.5 Are Commonly Used For Film Rolling Shafts, And Some High-power Models May Adopt A Thicker Shaft Design; The Control System Integrates Limit Switches, Relays, And Other Components, And Some Models Are Also Equipped With Remote Controls For More Convenient Operation. The Body Is Often Made Of Aluminum Alloy Material And Treated With Spray Coating, Which Combines Lightweight And Anti-corrosion Characteristics. Some Products Also Have Anti Condensation Drainage Holes, With A Protection Level Of Up To IP55.
Mainstream Types: Can Be Divided Into Side Roll And Top Roll According To Usage Scenarios, Suitable For Different Window Positions In Greenhouses; According To The Type Of Power Supply, There Are DC 24V And AC 220V Models, Among Which The 220V AC Motor Model Can Be Directly Connected Without The Need For A Transformer, Resulting In Lower Installation Costs; According To Function, It Can Be Divided Into Ordinary Type And Intelligent Temperature Control Type. The Intelligent Type Can Be Linked With Greenhouse Sensing Equipment To Achieve Automatic Control; There Is Also A Hand Cranked Electric Dual-purpose Model, Which Can Handle Special Situations Such As Sudden Power Outages.
Significant Advantages And Practical Value
Time Saving, Labor-saving, And Doubled Efficiency: Compared To Manual Film Rollers, Electric Film Rollers Do Not Require Manual Climbing Or Repeated Shaking Of The Handle. With Just One Click Operation, The Film Can Be Rolled Easily. One Device Can Roll Up To 120 Meters Of Greenhouse Film, Greatly Reducing Labor Input, Especially Suitable For Large-scale Greenhouse Parks.
Precise Regulation And Protection Of Greenhouse Film: Equipped With A Precise Stroke Adjustment Device, The Height And Number Of Turns Of The Film Can Be Set Through A Knob, With High Adjustment Accuracy, To Avoid Excessive Film Damage To The Greenhouse Film. And The Equipment Mostly Adopts Low-speed And Uniform Operation Mode, With Stable Output Torque, Which Can Not Only Cope With Heavy Greenhouse Film, But Also Avoid Problems Such As Lagging And Tearing During The Film Rolling Process.
Strong Protection And Wide Adaptability: It Has Multiple Protection Functions Such As Rainwater Prevention, Anti Condensation, Anti Overload, And Anti Misconnection. Some Products Can Also Withstand A Wide Temperature Range Of -20 ℃~60 ℃, And Are Suitable For Use In Outdoor Greenhouses Under Different Climatic Conditions. Whether It Is Vegetable Greenhouses, Flower Greenhouses, Seedling Greenhouses, Or Breeding Sheds, They Can All Play A Good Regulatory Role.
Cost Controllable, Worry Free After-sales Service: Most Mainstream Models Are Affordable And Have Low Power Consumption, Making Long-term Usage Costs Controllable. Legitimate Brands Such As Kailite Also Offer A Three-year Warranty Service To Reduce Maintenance Concerns In The Later Stages.
Key Points For Installation, Maintenance, And Selection
Installation Precautions: Installation Should Be Carried Out By Professional Personnel. When Wiring, The Grounding Terminal Should Be Connected To The Ground Wire. After Wiring, The Junction Box Should Be Sealed To Prevent Water Ingress; Less Than 5 Devices Can Be Used In Parallel, And If More Than 5 Devices Are Needed, An Electrical Control Device Must Be Added. After Installation, It Is Necessary To Check Whether The Film Roll Axis Is Straight. During Trial Operation, Confirm That The Film Roll And Release Directions Are Normal. Finally, Cover The Waterproof Cover And Fix The Power Cord To Avoid Entanglement And Breakage During Film Roll.
Daily Maintenance Skills: It Is Necessary To Regularly Add Antifreeze Gear Oil And Conduct Comprehensive Maintenance Once A Year; Regularly Check Whether The Screws Between The Host And The Connection Are Loose, And Whether The Welding Joints Are Cracked; After Each Use, Promptly Cut Off The Main Power Supply And Add A Knife Switch Near The Control Switch To Improve Electrical Safety. At The Same Time, Avoid Hitting The Body With Metal Objects, Stay Away From Acidic And Alkaline Substances, And Do Not Require Additional Oil Lubrication.
Scientific Selection Suggestion: It Is Necessary To Choose A Model That Is Suitable For The Length And Span Of The Greenhouse, Such As A 60W Power Model That Can Adapt To A Roll Film Length Of ≤ 85 Meters, And A 100W Model That Can Adapt To A Roll Film Length Of ≤ 100 Meters; Choose Products With Torque Matching Based On The Thickness And Weight Of The Greenhouse Film, And Prioritize High Torque Models For Thick Greenhouse Films; Attention Should Be Paid To The Low-temperature Operation Performance Of Equipment In Cold Northern Regions, While In Rainy Areas, The Focus Should Be On Checking The Protection Level.
