The greenhouse shall be equipped with an air release system during construction
The main purpose of the air release system is to adjust the temperature and humidity of the greenhouse
When the greenhouse temperature is higher than the growth demand of crops, we shall open the air outlet to cool the greenhouse
Similarly, when the humidity is high, we shall open the air outlet to drain the humidity, so as to make the crops grow
Before the expansion and closing of the air vent, it was manually operated and pulled up section by section by hand, which was laborious and laborious
Later, it evolved into a manual film reeler and an electric film reeler
Let's share the manual and electric film reelers with you
1、   Manual film reeler
The manual film reeler is installed on the film reeling liver after the greenhouse is completed, and the other side is fixed on the climber
The climber is fixed on the climbing rod, and the lower air outlet of the greenhouse can be closed and expanded by manually shaking the winding rod
The upper air outlet of the greenhouse is generally 3 to 4 meters high on the greenhouse floor
Similarly, we also install it in the same way as the lower air outlet
The difference is that we install a guide chain with a downward sag of about two meters at the upper air outlet, Retract and unfold the upper air outlet by pulling the guide chain
We must straighten the film rolling rod after installing the film rolling device in the greenhouse, so as to meet the subsequent use of the greenhouse

2、   Electric film reeler
If the electric film reeler is used, it must be matched appropriately in length
The installation method is the same as that of manual
The characteristics replace the manual film reeler to realize rapid film reeling, film release and automatic control of greenhouse environment
It has the characteristics of light weight, large output torque, output self-locking, high stroke adjustment accuracy, large adjustment range, rain proof, anti condensation and low power consumption
It is suitable for use under different climatic conditions
1
Loosen the locking screws on the two stroke adjusting buttons of the electric film reeler, turn the stroke adjusting button so that the two gear ring bosses are not pressed on the microswitch contacts
Pull the reversing switch of the power supply and the electric film reeler starts to work
At this time, confirm the “ Film rolling direction &rdquo& ldquo; Film release direction ” Location

2
Set the power reversing switch to “ Film rolling direction ” Position, turn any stroke adjusting knob manually to make the gear ring boss press the contact of the microswitch (a click can be felt)
At this time, if the electric film winder motor stops rotating, it means that the adjusting knob is used to adjust “ Roll film ” Direction of travel
If the motor does not stop rotating, it means that another adjusting button is used to adjust “ Roll film ” Direction of travel

3
Set the power reversing switch to “ Film rolling direction ” Position, rotate by hand “ Film rolling direction ” The stroke adjusting knob adjusts the film winding stroke
After confirming the film winding stroke, gently pull up the knob
Place the power supply at “ Film release direction ” Position, rotate by hand “ Film release direction ” The stroke adjusting knob adjusts the film release stroke
After confirming the film release stroke, gently pull up the knob

It is good for you to choose the film rolling device suitable for your greenhouse in the greenhouse project
