[0024] Example 2:

[0025] Please see Figures 1-4 This utility model discloses a multi-stage linkage fabric inspection machine pressing mechanism and anti-deviation limiting device, including a servo motor 401 on the side of the operating table 1; the left side of the servo motor 410 is fixedly connected to a lead screw 402; the outer wall of the lead screw 402 is threadedly connected to a threaded sleeve 403; the threaded sleeve 403 is slidably connected along a through groove on the inner side of the operating table 1; the top of the protruding parts on both sides of the threaded sleeve 403 is fixedly connected to a concave limiting block 404; rollers 405 are slidably provided on both the upper and lower sides inside the concave limiting block 404, and an elastic element is provided at the gap between the top of the central shaft of the roller 405 and the inner wall of the concave limiting block 404; the concave limiting block 405... 04 is fixedly connected to the infrared sensor 406 at the rear; the elastic element between the roller 405 and the inner wall of the concave limiting block 404 is a compression spring, with its two ends fixed to the top of the central shaft of the roller 405 and the inner wall of the concave limiting block 404 respectively; the installation angle of the infrared sensor 406 is adjustable, and its detection range is the edge of the fabric.

[0026] The working principle of the multi-stage linkage fabric inspection machine pressing mechanism and anti-deviation limiting device based on the above embodiments is as follows:

[0027] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0028] Second, the fabric is conveyed forward by the conveyor belt 302 on the operating table 1 under the drive of the transmission roller 301. The control cylinder 310 detects the real-time pressure through a pressure sensor at the end of the piston rod 309's stroke, thereby adjusting the piston rod 309 to provide downward pressure to the pressure roller 303, forming initial fabric pressing. The active pressure roller 305 is fixed by the first bearings 304 on both sides, and the passive pressure roller 306 is connected to the spring 308 through the second bearing 307 to form an elastic pressing force, adapting to fabrics of different thicknesses. The cylinder 310 detects the real-time pressure through a pressure sensor at the end of the piston rod 309's stroke, thereby adjusting the piston rod 309 to provide downward pressure to the active pressure roller 305. Pressure, combined with the dynamic buffer of spring 308, ensures that the fabric is flat and does not slip, forming a multi-stage fabric pressing structure; servo motor 401 drives lead screw 402 to rotate, causing screw sleeve 403 to move laterally along the inner through groove of operating table 1. Screw sleeve 403 drives concave limit block 404 to move laterally, adjusting the limit width to adapt to different fabric widths. Roller 405 in concave limit block 404 contacts the fabric through elastic element, reducing friction and guiding the fabric to center. Symmetrically set infrared sensors 406 monitor the edge position of the fabric in real time. If an offset is detected, the signal is fed back to PLC controller, which controls servo motor 401 to dynamically adjust the position of limit block to achieve automatic correction.

It includes a transmission roller 301, a conveyor belt 302, a multi-stage pressing roller mechanism, and an anti-deviation limiting device.

The anti-deviation limiting device is driven by a servo motor 401, which drives a lead screw 402 to move a concave limiting block 404. Combined with a symmetrical infrared sensor 406, the fabric position is monitored in real time.
