[0036] The moving mechanism 60 includes two telescopic mechanisms V61, the two telescopic mechanisms V61 are respectively fixedly connected to two sliding brackets I12, the telescopic ends of the two telescopic mechanisms V61 are fixedly connected to sliding brackets III62, the two sliding brackets III62 are rotatably connected to screw rods IV63, and the sliding brackets III62 are fixedly connected to a power mechanism V for driving the screw rod IV63 to rotate;

[0037] The clamping mechanism 70 includes two sliding seats II 71 and two conical wheels 72 rotatably connected to the two sliding seats II 71, the sliding seats II 71 are slidably connected to the sliding bracket III 62, the sliding seats II 71 are connected to the screw rod IV 63 by threads, and the sliding seats II 71 are fixedly connected to a power mechanism VI for driving the conical wheels 72 to rotate;

[0038] A winding drum 73 is clamped between the two conical wheels 72, and two clamping arc plates 74 are slidably connected to the winding drum 73. An elastic plate 75 is fixedly connected between one side of the two clamping arc plates 74, and a clamping groove is formed between the other sides of the two clamping arc plates 74. An electromagnet 76 capable of attracting the two clamping arc plates 74 is fixedly connected to the winding drum 73;

[0039] When using, Figure 1 As shown, the test fabric 80 to be tested is placed between the two clamping rollers 22, the power mechanism V is started, the output shaft of the power mechanism V starts to rotate, the output shaft of the power mechanism V drives the screw rod IV63 to rotate, and when the screw rod IV63 rotates, it drives the sliding seat II71 to move through the thread, so that the sliding seat II71 slides laterally on the sliding bracket III62, the sliding seat II71 drives the conical wheel 72 to move, and the conical wheel 72 drives the winding drum 73 to move, and the end of the test fabric 80 is placed between the two clamping arc plates 74, and the electromagnet 76 is energized. The clamping arc plates 74 are made of iron, so the electromagnet 76 generates a magnetic force to attract the two clamping arc plates 74, so that the two clamping arc plates 74 are close to each other, and the two clamping arc plates 74 clamp the end of the test fabric 80, and the elastic plate 75 is made of rubber material;

[0040] Start the power mechanism V, the output shaft of the power mechanism V starts to rotate, the output shaft of the power mechanism V drives the screw rod IV63 to rotate, when the screw rod IV63 rotates, the sliding seat II71 is driven to move through the thread, so that the winding drum 73 drives the detection fabric 80 to move, and the detection fabric 80 passes through the cutting mechanism I40, the detection mechanism 30 and the cutting mechanism II50 in sequence;

[0041] The power mechanism VI is started, and the output shaft of the power mechanism VI starts to rotate, the output shaft of the power mechanism VI drives the conical wheel 72 to rotate, the conical wheel 72 drives the winding drum 73 to rotate, and the winding drum 73 drives the detection fabric 80 to move, so that the detection fabric 80 is wound on the winding drum 73. During the winding process of the winding drum 73, the detection fabric 80 continuously passes through the lower end of the detection mechanism 30;

[0042] The detection instrument 32 may be an optical detection instrument, an ultrasonic detection instrument, a laser detection instrument, an infrared detection instrument, etc., which are commonly used in the art for detecting fabrics. Further, the telescopic mechanism I31 may be started, and the telescopic mechanism I31 may be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I31 drives the detection instrument 32 to move, thereby adjusting the relative distance between the detection instrument 32 and the detection fabric 80.

[0043] When damage or defects are detected on the test fabric 80, the telescopic mechanism II42 and the telescopic mechanism IV52 are started. The telescopic mechanism II42 and the telescopic mechanism IV52 can be hydraulic cylinders or electric push rods. The telescopic ends of the telescopic mechanism II42 and the telescopic mechanism IV52 drive the cutting tool I43 and the cutting tool II53 to move. The two cutting tools I43 approach each other, and the two cutting tools II53 approach each other, thereby completing the cutting of the damaged or defective position of the fabric.

[0044] Further, the power mechanism III and the power mechanism IV can be started, the output shaft of the power mechanism III drives the screw rod II 15 to rotate, the output shaft of the power mechanism IV drives the screw rod III 16 to rotate, when the screw rod II 15 rotates, it drives the cutting mechanism I 40 to move through the thread, thereby adjusting the position of the cutting mechanism I 40, when the screw rod III 165 rotates, it drives the cutting mechanism II 50 to move through the thread, thereby adjusting the position of the cutting mechanism II 50;

[0045] Furthermore, during the cutting process, the telescopic mechanism III 44 is started. The telescopic mechanism III 44 may be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 44 drives the clamping plate 45 to move. The two clamping plates 45 clamp the detection fabric 80 to ensure that the detection fabric 80 does not fall after being cut.

[0046] After the cutting is completed, the winding drum 73 continues to rotate, and after the remaining part is stored, the telescopic mechanism V61 is started. The telescopic mechanism V61 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism V61 drives the sliding bracket III62 to move, so that the two conical wheels 72 move away from each other, the winding drum 73 is removed, and a new winding drum 73 is replaced, and the power mechanism V is started. The output shaft of the power mechanism V drives the screw rod IV63 to rotate, so that the newly replaced winding drum 73 moves to the front side of the two clamping plates 45. Since there is a certain distance between the clamping plate 45 and the cutting tool I43, after cutting, a part of the fabric will remain at the front end of the clamping plate 45. After the two clamping arc plates 74 on the winding drum 73 clamp this part of the fabric, the detection fabric 80 is pulled to move, so that the detection fabric 80 passes through the cutting mechanism I40, the detection mechanism 30 and the cutting mechanism II50 again in sequence.
