Continuously rotating the adjusting ring 74 can tightly install the reel on the rotating shaft 72. The outer wall of the rotating shaft 72 is rotatably connected with the outer wall of the roller 3 through the toothed belt 8. The driving motor 71 drives the rotating shaft 72 to rotate, and the roller 3 rotates at the same time, which can reduce the friction between the steel strip and the roller 3.

[0035] Working principle:

[0036] When in use, the pickling box 1 is filled with pickling liquid. The stainless steel ultra-flat steel strip on the production line passes through the cleaning device 2 before entering the pickling box 1. The steel strip passes between the first fixed plate 21 and the mounting plate 24. The staff first adjusts the gap between the two wiping plates 25 according to the thickness of the steel strip, and rotates the pressure plate 27 on the limit rod 26 to make the pressure plate 27 rise and fall on the limit rod 26. At the same time, the compression spring 23 is compressed, so that the mounting plate 24 is close to the first fixed plate 21. When the two wiping plates 25 are respectively in contact with the two sides of the steel strip, the rotation of the pressure plate is stopped. 27. When the steel strip is conveyed, the dust and impurities on its surface are removed by the wiping plate 25, and then the staff covers the steel strip over the roller 3. A long groove is provided on the cover plate 9 to reduce the volatilization of the pickling solution, which is large enough for the steel strip to pass through, and the two sides of the steel strip do not contact the edges of the long groove. Then the steel strip passes under the pressing roller 4. The pressing roller 4 can ensure that the steel strip is immersed in the pickling solution, and corrosion-resistant sealing rings 5 ​​are installed at both ends of the pressing roller 4 to avoid the pickling solution from entering the contact part of the pressing roller 4 and the pickling box 1 as much as possible. Finally, the steel strip passes through the transition roller 6 and passes through the cleaning device 2 to reach the winding device 7.

[0037] The staff forcefully pulls out the bracket 76, removes the adjusting ring 74, and puts the reel for winding the steel strip on the rotating shaft 72, and makes it close to the friction pad 75 on the fixing ring 73, then puts the adjusting ring 74 on the rotating shaft 72 again, rotates the adjusting ring 74 to make it close to the reel, and continuously rotates the adjusting ring 74 to tightly install the reel on the rotating shaft 72. Since only one side of the outermost adjusting ring 74 is equipped with the friction pad 75, the other adjusting rings 74 are equipped with friction pads 75 on both sides, multiple reels can be set on the rotating shaft 72, so that the pickling device can pickle multiple steel strips in this way. After installing the reel, the staff reinserts the bracket 76 to provide support for the end of the rotating shaft 72 away from the drive motor 71; The adjustment method of the mounting plate 24 is the same. The gap between the second fixed plate 22 and the mounting plate 24 is adjusted so that the wiping plate 25 can wipe the liquid on the steel strip after pickling, and the upper surface of the second fixed plate 22 is an inclined surface to facilitate the passage of the steel strip. When the head end of the steel strip reaches the reel on the rotating shaft 72, the staff sticks the steel strip to the reel, and the driving motor 71 drives the rotating shaft 72 to rotate. At the same time, the reel drives the steel strip to rotate, so that the steel strip is wound on the reel. The rotation speed of the driving motor 71 is consistent with the speed of transmitting the steel strip on the production line, and the speeds are relatively slow, which can ensure that the steel strip fully reacts with the pickling liquid in the pickling box 1. The rotating shaft 72 and the roller 3 are connected by a toothed belt 8, that is, the roller 3 rotates at the same time, which can reduce the friction between the steel strip and the roller 3.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
