The distance between the line and the cloth 2, the roller 706 is evenly installed with a rolling ball 707, and the motor 3 drives the rotating shaft 4, the installation roller 701 and the roller 706 to rotate. When the ball 707 on the roller 706 contacts and rolls with the cloth 2, the second spring 705 cooperates with the ball 707 to generate an outward force on the cloth 2, and the reverse rotation of the front and rear two groups of installation rollers 701 is cooperated to achieve the flattening effect on the cloth 2; the laser scanning device 8 is a detection component composed of a laser light source, an optical transmission system and a receiver, and the laser scanning device 8 is fixedly connected to the main box 1 through a connecting rod 801;

[0030] The cleaned cloth 2 continues to move to the right. Figure 1-Figure 6 As shown, when the rotating shaft 4 rotates, the installation roller 701, the roller 706 and the ball 707 can be driven to rotate synchronously. When the ball 707 on the roller 706 contacts the cloth 2, since the distance between the roller 706 and the cloth 2 is greater than the distance between the central axis of the rotating shaft 4 and the cloth 2, the roller 706, the ball 707 and the installation frame 703 are forced to move relative to the bracket 702, and the sliding guide effect between the slide bar 704 and the bracket 702 can ensure that the roller 706, the ball 707 and the installation frame 703 are in contact with the cloth 2. 03 Movement stability, at this time, the second spring 705 is contracted by force, and when the roller 706 and the ball 707 continue to rotate, the second spring 705 provides force for the roller 706 and the ball 707, so that the ball 707 generates an outward pulling force on the cloth 2, and cooperates with the front and rear two groups of smoothing mechanisms 7 to realize the automatic flattening of the cloth 2, ensuring the flatness of the cloth 2 under the laser scanning device 8, and cooperates with the laser scanning device 8 to detect the cloth 2, so as to determine whether there are defects on the cloth 2;

[0031] The shaping mechanism 9 includes a movable frame 901, a hot pressing roller 902, a limiting frame 903, a guide rod 904 and a swash plate 905. The movable frame 901 is arranged in the main box 1, and the hot pressing roller 902 is connected to the bearing on the movable frame 901, and the hot pressing roller 902 contacts the cloth 2 and can roll.

[0032] After the defect detection on fabric 2 is completed, Figure 1-Figure 6 As shown, at this time, the cloth 2 continues to move to the right. When the cloth 2 moves to contact the hot pressing roller 902, the rotating shaft 4 rotates, which can synchronously drive the inclined plate 905 to rotate. With the sliding action between the inclined plate 905 and the limiting frame 903, the movable frame 901 and the hot pressing roller 902 are forced to make orderly left and right movements. With the sliding guiding action between the limiting frame 903 and the guide rod 904, the stability of the movement of the movable frame 901 and the hot pressing roller 902 can be guaranteed. Through the movement and rolling action of the hot pressing roller 902, the hot pressing shaping effect of the cloth 2 can be achieved, and the flatness of the cloth 2 after being smoothed by the smoothing mechanism 7 can be guaranteed. Finally, the cloth 2 after hot pressing shaping can be rolled up by the winding device. This is the working principle of the hot air non-woven fabric defect detection device.
