A rotating rod 10 is fixedly connected to the other end of the vertical rod 9, and a rotating rod 10 is fixedly connected to the other end of the rotating rod 10. The top of the sliding block 11 and the connecting plate 5 is fixedly connected to the sliding plate 12. The sliding block 11 and the sliding plate 12 are slidably connected. The outer side of the sliding block 11 is fixedly connected to the scraper 13. The outer side of the fabric winding machine 1 is equipped with a smoothing mechanism 2, which is used to smooth the fabric. The top of the multiple safety light grid rods 3 is provided with a mounting rod 22. The top of the mounting rod 22 is provided with a light bulb 23, which serves as illumination. The middle left side of the outer wall of the fabric winding machine 1 is fixedly connected to the placement block 24. The outer side of the placement block 24 is fixedly connected to the hook 25, which can be used to hang some tools.

[0040] Specifically, when motor 6 starts, its output will drive turntable 7 to rotate. The outer shaft 8 of turntable 7 will then drive the upright 9 to rotate, and the rotating rod 10 connected to the other end of the upright 9 will also move, causing the sliding block 11 connected to the rotating rod 10 to slide on the sliding plate 12 on the top of the connecting plate 5. Since a scraper 13 is fixed on the outer side of the sliding block 11, the scraper 13 will move with the sliding block 11, thereby cleaning the surface of the photoelectric sensor 4, effectively preventing dust and debris from obstructing the sensor surface, ensuring that the safety light grid device can accurately monitor the working area of ​​the winding machine, ensuring the safety of the winding machine operation, giving full play to its safety protection function, and avoiding safety accidents caused by monitoring errors. A light bulb 23 is installed on the safety light grid rod 3, and a mounting block 24 is installed on the winding machine 1, with a hook 25 on the mounting block 24 for hanging some tools.

[0041] Reference Figure 1 and Figure 5The smoothing mechanism 2 includes a fixed plate 201, which is installed on the outside of the fabric winding machine 1. A support leg 202 is fixedly connected to the top of the fixed plate 201, and a rotating rod 203 is rotatably connected to the top of the support leg 202. A sliding groove rod 204 is fixedly connected to the top left side of the fixed plate 201. A sliding block 205 is slidably connected inside the sliding groove rod 204. A toothed rod 206 is fixedly connected to the outside of the sliding block 205, and a connecting rod 207 is fixedly connected to the outside of the toothed rod 206.

A frame 19 is fixedly connected to the outside of bearing plate 18 to provide support.

[0042] Specifically, the support leg 202 is set at the upper end of the fixed plate 201 to provide necessary support for the rotating rod 203, ensuring that it can rotate freely. In the sliding groove rod 204 on the upper left side of the fixed plate 201, the sliding block 205 can slide smoothly. The movement of the sliding block 205 will drive the toothed rod 206 to move accordingly. When the rocker arm 210 on the mounting plate 209 rotates, it will cause the metal gear 211 to rotate accordingly. Since there is a meshing relationship between the metal gear 211 and the toothed rod 206, it can push the toothed rod 206 to slide in the sliding groove rod 204. The movement of the sliding block 205 is transmitted through the connecting rod 207, thereby driving the movement of the rotating rod 208, so that the device can adapt to the smoothing of fabrics of different sizes. At the bottom of the outer frame 15, the support plate 18 is supported, and a frame 19 is fixed on the outside of the support plate 18. The motor 6 is model M3508, and the photoelectric sensor 4 is model E3Z-D61.

[0043] Reference Figure 1 and Figure 2 The bottom of the fabric winding machine 1 is fixedly connected to a placement box 14, the bottom of the placement box 14 is fixedly connected to an outer frame 15, a warning sign 16 is provided on the lower right side of the outer wall of the outer frame 15, and a screw 17 is threadedly connected to the outer side of the warning sign 16. A storage box 20 is installed on the support plate 18, and a cover plate 21 is provided on the top wall of the storage box 20 for storing some items.

[0044] Specifically, a storage box 14 is installed on the fabric winding machine 1 to store some tools, a warning sign 16 is installed on the outer frame 15 and is fixed by screws 17 to serve as a warning, and a storage box 20 is installed on the support plate 18 to store some items.

[0045] Working principle: When motor 6 starts, its output end drives turntable 7 to rotate. The outer shaft 8 of turntable 7 then drives the upright 9 to rotate. The rotating rod 10 connected to the other end of the upright 9 also moves, causing the sliding block 11 connected to the rotating rod 10 to slide on the sliding plate 12 on the top of the connecting plate 5. Since a scraper 13 is fixed on the outer side of the sliding block 11, the scraper 13 will move as the sliding block 11 slides, thereby cleaning the surface of the photoelectric sensor 4. This effectively prevents dust and debris from obstructing the sensor surface, ensuring that the safety light curtain device can accurately monitor the working area of ​​the winding machine, ensuring the safety of the winding machine's operation, giving full play to its safety protection function, and avoiding safety accidents caused by monitoring errors.

[0046] The support leg 202 is located on the top of the fixed plate 201, providing support for the rotating rod 203 so that it can rotate freely. In the sliding rod 204 on the top left of the fixed plate 201, the sliding block 205 can slide smoothly. The movement of the sliding block 205 drives the toothed rod 206 to move accordingly. When the rocker arm 210 on the mounting plate 209 rotates, it drives the metal gear 211 to rotate accordingly. Since there is a meshing relationship between the metal gear 211 and the toothed rod 206, it can push the toothed rod 206 to slide in the sliding rod 204. The movement of the sliding block 205 is transmitted through the connecting rod 207, which in turn drives the movement of the rotating rod 208, so that the device can adapt to the smoothing of fabrics of different sizes.
