How to conduct daily maintenance of greenhouse film?

1. periodic inspection

Check the film winder:

Appearance inspection: check whether the shell of the film retractor is damaged, deformed or rusted. If problems are found, repair or replace the shell in time to prevent damage to internal components.

Operation inspection: manually operate the film winder to check whether it rotates smoothly and whether there is any jam or abnormal noise. If there is a problem, it may be that the gears, chains and other parts are worn or damaged and need to be repaired or replaced.

Motor inspection (if it is an electric film retractor): check whether the motor is running normally, whether there is overheating, abnormal noise, etc. At the same time, check whether the power cord of the motor is firmly connected and whether there is any risk of damage or short circuit.

Inspect the film:

Check the film for damage, tears, or perforations. If a small damage is found, you can use a special film repair tape to repair; if the damage is large, the film should be replaced in time.

Check the fixation of the film to ensure that the film is firmly fixed on the greenhouse frame by the circlip or the film pressing line. If the circlip is found to be loose or the pressure line is broken, it should be tightened or replaced in time.

Check the drive components:

For manual film reels, check whether the transmission parts such as gears, chains and transmission shafts are worn, loose or deformed. If a problem is found, it should be adjusted, tightened or replaced in time.

For the electric film winder, check whether the coupling, belt or chain between the motor and the film winding shaft is working properly. If there is any abnormality, it should be repaired or replaced in time.

2. cleaning and maintenance

Film roller cleaning:

Regularly clean the dust and dirt on the surface of the film reel, which can be wiped with a clean damp cloth. Avoid using corrosive cleaning agents to avoid damage to the housing and internal components of the film reel.

For electric film reels, attention should also be paid to cleaning the cooling fan and vents of the motor to ensure the normal heat dissipation of the motor.

Film cleaning:

When appropriate, the film can be cleaned to improve its light transmittance. You can use a soft damp cloth to gently wipe the surface of the film to remove dust and dirt. Avoid scratching the film with sharp tools or hard objects to avoid damaging the film.

If there are stubborn stains on the surface of the film, you can use a mild detergent for cleaning, but pay attention to avoid the impact of detergent residues on crops.

Lubrication of transmission components:

For the transmission parts such as gears, chains and transmission shafts of the manual film winder, an appropriate amount of lubricating oil or grease can be applied regularly to reduce friction and wear and extend its service life.

For the electric film reel, lubrication and maintenance should be carried out in accordance with the operation instructions of the motor to ensure the normal operation of the motor.

3. considerations

Operation specification:

When operating the film reel, it should be operated in the correct way to avoid excessive force or forced torsion. For electric film reels, frequent starting and stopping should be avoided to avoid damage to the motor.

In the process of rolling or placing the film, attention should be paid to observe the operation of the film to avoid the film being stuck or wound on the roll film shaft. If there is a problem, the operation should be stopped in time and adjusted.

Severe Weather Protection:

In case of strong wind, rainstorm, blizzard and other bad weather, the film should be put down and fixed in advance to prevent the film from being damaged. At the same time, the firmness of the film reel and the greenhouse frame should be checked to ensure that they can withstand the impact of bad weather.

After the bad weather, the film and the film roller should be checked in time. If there is any damage, it should be repaired or replaced in time.

Regular maintenance:

Formulate regular maintenance plan, according to the plan to conduct a comprehensive inspection, cleaning and maintenance of greenhouse film. Regular maintenance can find and deal with problems in time, avoid the expansion of the problem, and ensure the normal operation of the film rolling system.
