Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-5 , an embodiment provided by the present invention:

[0021] Blowing protection device: including a bottom plate 1, a support frame 11 is fixedly connected to the surface of the bottom plate 1, a bearing 12 is fixedly connected to the surface of the support frame 11, a blowing pipe 13 is rotatably connected to the surface of the bearing 12, a blowing nozzle 14 is fixedly installed on the surface of the blowing pipe 13, one end of the blowing pipe 13 is fixedly connected to an air inlet pipe 15, the air inlet pipe 15 conveys gas to the blowing pipe 13, and the blowing pipe 13 then outputs the gas to the steel strip through the blowing nozzle 14. The other end of the blowing pipe 13 is fixedly connected to a connecting rod 22, a first motor 2 is fixedly connected to the surface of the bottom plate 1, a worm 21 is fixedly connected to the output shaft of the first motor 2, and a worm gear 23 is fixedly connected to the surface of the connecting rod 22. This blowing protection device can change the blowing angle of the blowing nozzle 14, thereby changing the blowing air flow angle of the blowing nozzle 14. By changing the angle of the air flow action on the steel strip and the steel coil, the use effect of the blowing protection device is guaranteed.

[0022] Furthermore, an adjustment mechanism is provided at the bottom of the bottom plate 1. The adjustment mechanism includes an adjustment frame 3. The adjustment frame 3 is arranged directly below the bottom plate 1. A guide rail 31 is fixedly connected to the surface of the adjustment frame 3. A slider 32 is slidably connected to the surface of the guide rail 31. A second motor 33 is fixedly connected to the surface of the adjustment frame 3. A lead screw 34 is fixedly connected to the output shaft of the second motor 33. A square nut 35 is threadedly connected to the surface of the lead screw 34. The bottom plate 1 is fixedly connected to the surface of the square nut 35. Its adjustment mechanism can adjust the positions of the purge pipe 13 and the purge nozzles 14, thereby changing the distance between the purge nozzles 14 and the steel strip and the steel coil, and further changing the purge pressure of the purge nozzles 14. If the distance is too close, it may cause excessive purge pressure and damage the surface of the steel strip; if the distance is too far, it may cause insufficient purge pressure and fail to effectively remove dirt. This adjustment mechanism enables the purge protection device to ensure the purge effect while avoiding damage to the surface of the steel strip.

[0023] Furthermore, the purge pipe 13 rotates on the surface of the support frame 11 through a bearing 12. A plurality of purge nozzles 14 are provided, and the purge nozzles 14 are linearly and evenly arranged on the surface of the purge pipe 13. The purge nozzles 14 rotate synchronously with the purge pipe 13. The purge nozzles 14 change the angle on the support frame 11 through rotation, thereby changing the angle of the airflow blown out by the purge nozzles 14.

[0024] Furthermore, the worm 21 rotates on the bottom plate 1 through the output shaft of the first motor 2. The worm 21 meshes with the worm gear 23. The worm gear 23 is arranged at one end of the purge nozzle 14. The worm gear 23 drives the purge pipe 13 to rotate on the support frame 11 through a connecting rod 22.

[0025] Furthermore, the worm 21 drives the worm gear 23 to rotate through rotation. The worm gear 23 drives the purge pipe 13 to rotate on the support frame 11 through a connecting rod 22. The purge pipe 13 drives the purge nozzles 14 to rotate, thereby completing the change of the purge angle of the purge nozzles 14.

[0026] Furthermore, two sets of guide rails 31 and sliders 32 are provided. The bottom of the bottom plate 1 is fixedly connected to the surface of the slider 32. The bottom plate 1 slides on the surface of the guide rail 31 through the slider 32. The slider 32 ensures the stability of the bottom plate 1 sliding on the adjustment frame 3.

[0027] Furthermore, the lead screw 34 rotates on the surface of the adjustment frame 3 through the output shaft of the second motor 33. The lead screw 34 drives the square nut 35 to slide on the surface of the adjustment frame 3 through rotation. The square nut 35 drives the bottom plate 1 to slide on the surface of the adjustment frame 3. The square nut 35 drives the support frame 11 to slide during the sliding process. The support frame 11 drives the purge pipe 13 and the purge nozzles 14 to slide on the surface of the adjustment frame 3, thereby changing the distance between the purge nozzles 14 and the steel strip, and thus facilitating the control of the airflow pressure of the purge nozzles 14.

[0028] Working principle: The output shaft of the first motor 2 drives the worm 21 to rotate. The worm 21 drives the worm wheel 23 to rotate through rotation. The worm wheel 23 drives the purging pipe 13 to rotate on the surface of the support frame 11 through the connecting rod 22. The purging pipe 13 changes the angle of the purging nozzle 14 during the purging process, thereby changing the angle of the purging air flow of the purging nozzle 14. By adjusting the angle of the purging nozzle 14, the dirt or burrs on the steel strip and steel coil can be effectively removed, ensuring the use effect of the purging protection device.

[0029] The bottom plate 1 slides on the surface of the guide rail 31 through the slider 32. The output shaft of the second motor 33 drives the lead screw 34 to rotate. During the rotation of the lead screw 34, the square nut 35 is driven to slide on the adjusting frame 3. The square nut 35 drives the bottom plate 1 to slide on the guide rail 31, thereby changing the position of the bottom plate 1 on the adjusting frame 3. The bottom plate 1 changes the positions of the purging pipe 13 and the purging nozzle 14 through the support frame 11, thereby changing the distance between the purging nozzle 14 and the steel strip, so as to conveniently control the air flow pressure of the purging nozzle 14, enabling the purging protection device to ensure the purging effect while avoiding damage to the surface of the steel strip.
