[0003] The patent document with the application number 202223047615.9 discloses a fabric printing and dyeing color difference detection device, which includes a placement plate, a colorimeter and a back plate. Brackets are fixedly connected to the left and right sides of the upper end surface of the placement plate. Bearings are fixedly connected to the upper end surfaces of the brackets. Rotating shafts are fixedly connected to the inner walls of the bearings. A roller is fixedly connected between the rotating shafts. The other ends of the rotating shafts are fixedly connected with turntables. Stirring rods are arranged on the outer curved surfaces of the turntables. A handle is fixedly connected to the left end surface of the left stirring rod.

[0004] However, for traditional visual detection devices for defects of fabric printing and dyeing, there are impurities and dust on the fabric surface, the recognition results of the machine are unstable, which is easy to cause misdetection, and the detection angle is limited, making it inconvenient to detect the fabric at the corner positions, and the flexibility is poor.

A cleaning roller 5 is sleeved on the circumferential outer wall of the axis through a bearing;

[0023] Adjusting mechanism: The adjusting mechanism is arranged on the inner walls of the opposite sides of the detection table 1 near the top.

[0024] In the detailed implementation mode, the cleaning mechanism uses the two first sliders 10 to slide in the first chutes 9 to adjust the distance between the cleaning rollers 5 to adapt to fabrics of different thicknesses. The cleaning rollers 5 can remove dust, impurities, etc. on the fabric surface, ensuring that the fabric remains clean during the detection process, thereby improving the accuracy and precision of the visual inspection system.

[0025] Reference Figure 2 and Figure 3 In a preferred embodiment, a threaded hole is formed in the outer wall of the top of the first slider 10, a screw 13 is installed inside the threaded hole, the bottom of the screw 13 is connected with a fixing block 12, and the fixing block 12 is used in cooperation with the axis.

The cleaning roller 5 can be conveniently disassembled and replaced for regular maintenance to ensure better cleaning effect during the fabric detection process.

[0027] Reference Figure 3 In a preferred embodiment, a first assembly groove 2 and a second assembly groove 14 are formed in the inner wall of the bottom of the detection table 1, and a fabric guiding roller 4 is connected to the inner walls of the first assembly groove 2 and the second assembly groove 14 through bearings.

[0028] As a device for supporting and guiding the fabric, the fabric guiding roller 4 can ensure that the fabric remains flat during operation, avoid wrinkles or twists during the transmission process of the fabric, and thus improve the detection accuracy of the fabric.

[0034] One end of the winding roller 16 is externally connected to the motor 8, so that the winding process of the fabric can be automatically controlled, realizing precise control of the fabric transmission speed and tension, which helps to improve the detection efficiency and accuracy and reduce the influence of human factors on the detection results.

[0035] Working principle: During use, the cleaning mechanism adjusts the distance between the cleaning rollers 5 by sliding two first sliders 10 in the first chute 9 according to fabrics of different thicknesses. The cleaning rollers 5 can remove dust, impurities, etc. on the fabric surface. Subsequently, the detection plates 7 at the bottoms of the two mounting brackets 6 move relatively in the horizontal direction and are adjusted according to the fabric width to avoid missed detection. The LED lights 18 mounted on the detection plates 7 are adjusted according to the color and texture of the fabric to obtain the best lighting effect, ensuring that the camera 19 captures more real and clear images.
