220V Electric Film Winding DeviceIt Is A New Generation Of Greenhouse Film Rolling Ventilation And Cooling Equipment, Used For Opening And Closing The Side And Top Windows Of Plastic Film Greenhouses, Replacing Traditional Manual Film Rollers To Achieve Rapid Film Rolling, Film Release, And Automatic Control Of Greenhouse Environment. It Drives The Film Winding Shaft To Rotate Forward And Backward Through A Motor, Rolling Or Unfolding The Film To Achieve Functions Such As Temperature Regulation, Air Exchange, And Lighting Control. It Is The Best Choice For Modern Solar Greenhouses.
Main Features
1. Directly Use 220V AC Power
It Can Be Directly Connected To An AC 220V Power Supply Without The Need For Power Conversion, Making Installation And Use More Convenient, Eliminating The Need For Transformers, And Reducing Supporting Investment Costs.
2. Low Working Current And Low Voltage Drop In The Circuit
Compared With 24V DC Coils, The Working Current Is Smaller, The Voltage Drop Of The Circuit Is Smaller, And The Efficiency Of Electric Power Utilization Is Higher, Which Is Conducive To Energy Conservation. The Power Cord Diameter Can Be About One-fifth Of The Same Type Of DC Coil, And The Wiring Cost Of The Product Is Relatively Low.
3. Prevent Misconnection And Overload
It Has The Function Of Preventing Misconnection, Even If The Live Wire L Of The Power Supply Is Connected To Both L Open And L Closed At The Same Time, The AC Coil Will Not Be Damaged, And It Can Work As Long As The Wire Is Reconnected. Anti Overload Design, Connecting The Wrong Wire Will Not Burn The Motor.
4. Accurate Limit Positioning And High Self-locking Performance
Accurate Limit Positioning, Higher Self-locking Performance, High Travel Adjustment Accuracy, And A Wide Adjustment Range. Equipped With Anti Condensation Drainage Holes, The Protection Level Reaches IP55 (waterproof And Dustproof).
5. Strengthen Processing At The Output End
Enhanced Processing At The Output Shaft End Results In Low Noise And High Torque. Provide A 5-meter-long External Power Cord For Easy Connection To The Control Box, Ensuring Safety And Reliability.
Working Principle
The 220V Electric Film Winding Device Operates Through Motor Drive. When The Drive Shaft Rotates, It Drives The Film Rolling Shaft To Rotate, And The Plastic Film Is Rolled Up Or Lowered Layer By Layer, Thereby Achieving The Opening And Closing Of The Ventilation Window. The Electric Coil Rotates To The Preset Ventilation Limit Position, Triggering The Ventilation Travel Switch, Cutting Off The Power Supply Of The Motor, And Stopping The Film Winding Of The Electric Coil; When The Electric Coil Rolls The Film Tube To Release The Film, The Greenhouse Is Closed, The Electric Coil Rotates To The Preset Sealing Limit Position, The Sealing Stroke Switch Is Triggered, The Power Supply Of The Motor Is Cut Off, And The Electric Coil Stops Releasing The Film.
