The specific working process is as follows:

when the device works, the support frame 1 is fixed on the upper edge of a window through the L-shaped screws 11, when the fabric 6 needs to be pulled and closed, the controller controls the main shaft of the second motor 3 to rotate, the main shaft of the second motor 3 rotates to drive the roller 5 to rotate, the roller 5 drives the conveyor belt 51 to rotate, the teeth 52 on the left conveyor belt 51 are meshed with the teeth 52 on the right conveyor belt 51, so that the left conveyor belt 51 drives the right conveyor belt 51 to move, the first electromagnet on the conveyor belt 51 on the left side is provided with a first electromagnet, the first electromagnet above the conveyor belt 51 on the left side is electrified after passing through the clamping ring 7 to attract the first steel ball 74 and the second steel ball 76 in the clamping ring 7, so that the clamping ring 7 on the left side of the roller 2 is pulled and the left fabric 6 is pulled and closed by the clamping ring 7 on the left side of the roller 2; the movement of the fabric 6 on the right side of the roller 2 is symmetrical to the movement of the fabric 6 on the left side of the roller 2, which is not described herein any more, and when the fabric 6 needs to be opened towards two sides, the second motor 3 rotates reversely, so that the fabric 6 moves towards two sides to be opened; the two ends of the intelligent electric curtain are hung on the L-shaped screws 11 on the two sides of the upper edge of the window, and the first opening 77 on the lower side of the clamping ring 7 is uniformly clamped at the upper end of the fabric 6, so that the intelligent electric curtain is installed, and the installation of the intelligent electric curtain is simplified; when the fabric 6 needs to be cleaned, the first opening 77 on the lower side of the clamping ring 7 is opened, the fabric 6 is taken down, and the fabric 6 is cleaned; therefore, the fabric 6 is more convenient to clean; the shape of the first opening 77 is arc-shaped, so that the clamping area of the first opening 77 and the upper end of the fabric 6 is increased, the upper end of the fabric 6 is clamped more firmly, and the fabric 6 is less prone to falling off from the first opening 77; when the fabric 6 needs to be rolled up, the controller controls the main shaft of the first motor 12 to rotate in the forward direction, the main shaft of the first motor 12 rotates in the forward direction to drive the roller 2 to rotate in the forward direction, and the roller 2 rotates in the forward direction to roll up the fabric 6; when the fabric 6 needs to be put down, the controller controls the main shaft of the first motor 12 to rotate reversely, so that the roller 2 rotates reversely, the roller 2 rotates reversely to put down the fabric 6, and the fabric 6 is rolled up and put down; when the fabric 6 needs to be reinforced and the fabric 6 is prevented from being blown apart, the controller controls the second magnet 10 to be electrified, the second magnet 10 attracts the first magnet 9 after being electrified, the first magnet 9 and the second magnet 10 are close to each other, the air pressure in the second cavity 78 is reduced, the inner side of the second cavity 78 expands outwards, the second clamping groove 75 is far away from the first clamping groove 73, the second steel ball 76 in the second clamping groove 75 is far away from the steel ball in the first clamping groove 73, when the controller controls the first motor 12 to rotate, the first motor 12 drives the roller 2 to rotate, the roller 2 only drives the inner ring 72 of the clamping ring 7 to rotate, the outer ring 71 cannot rotate, so that the fabric 6 cannot roll, the inner ring 72 of the clamping ring 7 rotates to drive the second steel ball 76 to rotate, the second steel ball 76 rotates to bring the iron wire 8 out of the first opening 77, and the iron wire 8 penetrates into the through hole 61 in the fabric 6, so that the fabric 6 is reinforced, and the fabric 6 is not easy to blow up. The first motor 12 rotates reversely, and the iron wire 8 can be retracted between the first steel ball 74 and the second steel ball 76; when the iron wire 8 extends out of the first opening 77, the iron wire 8 passes through between the compression rollers 93 of the first opening 77, and the iron wire 8 is rolled into the straight iron wire 8 by the compression rollers 93, so that the iron wire can penetrate into the through hole 61 of the fabric 6 more easily, and the fabric 6 can keep a vertical plane shape more easily; a third cavity is formed inside each of the first steel ball 74 and the second steel ball 76; half of the third cavity is filled with water, the water in the first steel ball 74 and the second steel ball 76 can absorb shock, reduce noise and absorb heat, so that the friction heat generated when the first steel ball 74 and the second steel ball 76 rotate is absorbed by the water, the specific heat capacity of the water is larger than that of the steel balls, the temperature of the first steel ball 74 and the second steel ball 76 rises more slowly, and the movement of the snap ring 7 is not easily influenced by the heat generated by the movement friction of the first steel ball 74 and the second steel ball 76.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
