Electric roller shutter structure type There are currently two types of roller shutter machines in China.
The fixed electric reducer is fixed on the top of the greenhouse and the coil is rolled up and down. Suitable for rolling grass curtains and cotton curtains.
The movable electric reducer is not fixed and can be lifted up and down with the roller tube. Mainly suitable for soft insulation.
Installation Precautions The fixing bracket must be firm when the fixed shutter is installed. Each bearing frame must be on the same line and concentric. The length of the roller cord and the elastic need to be carefully adjusted several times. The effect of the roller shutter is good. Different thicknesses of the straw curtains result in different diameters of the reels.
The movable electric shutter is currently used most commonly. The triangle bracket must be installed securely when installed. If necessary, it can be fixed with concrete. The binding method must be the same when the lower end of the cotton curtain is fixed on the same reel, and the amount of the cotton curtain around the shaft must be uniform. Roller shutter effect is good. Due to the heavy weight on the reducer side, the force of the cotton curtain is greater, so the cotton curtain will be rolled tightly so that the diameter of the spool is smaller than the diameter of the remote spool, making the slower side walk slowly. In this case, add a pad (such as a limb pad, a sack sheet, etc.) inside the belt and increase the diameter of the reel to ensure the effect of the roller shutter. Adjust the thickness of the pad in a timely manner.
When using, pay attention to the curtain, we must first remove the tubes and curtains of the goods, and in the greenhouse before the 2 meters allowed to stand people, to prevent the shutter machine abnormal phenomenon bruises.
The operator should stand on the side of the front of the gearbox so that the entire condition of the roller blind can be observed.
When putting up the rolling shutter, we must pay full attention to it. Do not leave it after turning on the power supply, causing the rolling shutter to continue to work after the roll is in place, so that the rolling shutter and the whole scroll roll down together from the ceiling of the greenhouse, causing great damage; Once in place, the formation of rewinding will also cause harm.
Humidity in the greenhouse environment is relatively high, and it is easy to leak electricity and power. After the operation is completed, the power supply must be cut off. This can also prevent misoperation caused by other people.
Lubricate the reducer regularly to ensure the long-term, normal and safe operation of the reducer.
No matter how you adjust it, it should be done under the condition of shutdown to prevent the clothing from being involved in injury.
Sunlight Greenhouse Electric Roller Use Note
The winter covering of traditional greenhouses is grass curtains and cotton curtains. These coverings have a large amount of work, especially in the winter. The use of electric shutters can be started at any time, prolonging the lighting time, increasing photosynthesis, and more importantly saving labor time and reducing labor intensity. According to the survey, during the deep winter production of solar greenhouses, it takes about 1.5 hours to artificially control the curtain for every 667 square meters of greenhouses, and the shutter takes only about 8 minutes. Before the sun goes down, it takes about 1 hour to manually put the curtain. From this point of view, if you put the curtain on a roller blind every day, you will save nearly two hours of time compared to manual labor. At the same time, it prolongs the valuable illumination time in the room and increases the photosynthesis time. In addition, the use of electric shutters to protect the straw curtains and cotton curtains has improved the service life of the straw curtains and the cotton curtains, which not only reduces the production cost, but also enhances their wind resistance due to their overall deployment.
