Description

Technical Field

[0001] The utility model relates to the field of automatic control, in particular to a double-stroke limit roller shutter machine and a roller shutter structure of a solar greenhouse. Background Art

[0002] In life, many devices, once running beyond the limit, will cause great economic losses, or even casualties. With the continuous development of science and technology, solar greenhouses have also been applied, which can meet the winter production of fruit and vegetable crops in northern regions and have significant economic benefits. Rolling machines are essential key environmental control equipment in solar greenhouses. Compared with manual rolling machines, the use of electric rolling machines can greatly save labor time, reduce labor intensity, save labor, and produce better economic benefits.

[0003] At present, the roller shutter machines commonly used in the market all use a single foot switch as the travel control mechanism. In actual use, every time the curtain goes up or down and presses the foot switch, the motor controller will send a power-off signal to realize the limit function. This kind of roller shutter machine with only one limit switch has a great risk of operation. If this single foot switch fails, the roller shutter machine will continue to work and exceed the working stroke, which will damage the greenhouse facilities at the least, and even fall from the top of the greenhouse at the worst, causing harm to the relevant personnel around the greenhouse and causing safety accidents.
