[0050] The dust blocking assembly 3 includes two positioning brushes 31 symmetrically disposed inside each fixed frame 11.

[0051] Preferably, a brake is provided on the motor 23. Under normal conditions, the brake is electrically automatically controlled. In an emergency, it can be manually controlled to release. The motor is equipped with a position encoder, and the opening / closing position can be freely set.

[0052] In this embodiment: When the curtain blades slide inside the two fixed frames 11, the two positioning brushes 31 will block external dust, preventing the dust from entering the inside of the fixed frames 11, and can also prevent the fingers of the staff from being pinched.

[0053] The working principle and usage process of the present utility model: When it is necessary to open or close the rolling shutter door, connect the motor 23 to an external power supply and start it. The first gear 24 will drive the second gear 25 to rotate, and the positioning rod 26 will be driven to rotate to wind up the curtain blades. The curtain blades will slide up and down inside the two fixed frames 11, thus realizing the electric opening and closing of the rolling shutter door. When performing maintenance on the motor 23, the cover plate 210 can be flipped to expose the motor 23, facilitating the maintenance of the motor 23. The first support rod 27 and the second support rod 28 will support the two positioning plates 21 to prevent the overall deformation of the rolling shutter door housing 1. The cover plate 210 is set to be detachable to facilitate the installation of the components inside the rolling shutter door housing 1. When the curtain blades slide inside the two fixed frames 11, the two positioning brushes 31 will block external dust, preventing the dust from entering the inside of the fixed frames 11, and can also prevent the fingers of the staff from being pinched.
