[0025] In addition, to clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The top, bottom, left, right, front, and back sides are shown.

[0026] like Figures 1 to 5 As shown, this application provides an online fabric inspection device for a single-sided circular knitting machine. The device includes: an image acquisition module 1, an image processing module 2, a first connecting bracket 3, and a second connecting bracket 4.

[0027] Specifically, the image acquisition module 1 is installed on the top crossbeam of the single-sided circular knitting machine via the first connecting bracket 3, and is used to realize the real-time acquisition of images of the fabric surface.

[0028] The first connecting bracket 3 includes a clamping structure 31, a first connecting member 32, a bending member 33, a rotating connecting member 34, and a mounting platform 35. The clamping structure 31 is used to fix it to the top crossbeam of the single-sided circular machine. One end of the first connecting member 32 is connected to the clamping structure 31, and the other end is connected to the bending member 33. The first connecting member 32 and the clamping structure 31 are in an adjustable connection relationship. The first connecting member 32 is movable along its axial direction and can be rotated around its axis, which is used to adjust the position of the image acquisition module 1 in the axial and rotational directions of the first connecting member 32. The rotating connecting member 34 is inserted into the bending member 33 and can rotate around its own axis. The mounting platform 35 is mounted on the rotating connecting member 34 and can move along the axial direction of the rotating connecting member 34, which is used to install the image acquisition module 1 and realizes the position adjustment of the image processing module 2 in the axial and rotational directions of the rotating connecting member 34.

[0029] The image processing module 2 is mounted on the top mounting ring of the single-sided circular machine via a second connecting bracket 4.

By adjusting the position of the second fastener 352 in the first arc-shaped mounting hole 351, the mounting angle of the image acquisition module 1 along the circumference of the rotating connector 34 can be adjusted. This structure significantly improves the adjustability and flexibility of the image acquisition module 1. By adjusting the position of the second fastener 352 in the arc-shaped mounting hole, precise alignment of the image acquisition module 1 can be achieved, adapting to the acquisition needs of different fabric surfaces and lighting conditions.

[0036] like Figure 5 As shown, the second connector 42 is provided with a groove 421 extending along its direction, and the support platform 43 is slidably disposed in the groove 421. This structure effectively improves the installation flexibility and docking accuracy of the image processing module 2. By guiding the vertical position adjustment of the support platform 43 through the groove 421, the image processing module 2 can quickly match according to the height of the circular knitting machine or the fabric tension, thereby improving the efficiency and accuracy of image analysis.

[0037] The support platform 43 is provided with a second arc-shaped mounting hole 431. The support platform 43 is fixed in the slide groove 421 by a third fastener 432 passing through the second arc-shaped mounting hole 431. By adjusting the position of the third fastener 432 in the second arc-shaped mounting hole 431, the horizontal mounting angle of the support platform 43 can be adjusted.
