(2) Roller shutters driven by belt

Advantages: general structure, better than rope transmission, relatively low noise, can be designed into a certain arc, relatively large transmission force, can drive heavy curtain cloth.

Disadvantages: high cost and average operating life of oil refining equipment. Because domestically produced plastic belts with such a thin and narrow hole have not completely passed the customs, the service life is generally difficult to exceed three years. The main reason is that the turning radius is too small and the time As the plastic ages, it cracks and becomes hard, which eventually leads to natural fracture. Therefore, imported products are generally used, but they are expensive. It is not possible to manually open and close the curtains during power failure.
