[0002] On a hot-dip galvanizing production line, the zinc pot submerged roller is an important roller that comes into direct contact with the strip steel in the galvanizing process. Due to the complex composition of zinc in the zinc pot and the high temperature, the working conditions of the zinc pot submerged roller are extremely harsh, especially the large amount of zinc dross generated by the substitution of iron. This zinc dross adheres to the submerged roller inside the zinc pot, so it needs to be cleaned with a scraper.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 An embodiment of this utility model provides an online cleaning device for submerged rollers in a hot-dip galvanizing production line, comprising a fixed frame 1, an electric telescopic rod 3 fixedly connected to the top inner part of the fixed frame 1, a lifting frame 4 fixedly connected to the output end of the electric telescopic rod 3, and the lifting frame 4 being lifted and slid by the operation of the electric telescopic rod 3. The submerged roller body 2 is rotatably connected inside the fixed frame 1. The submerged roller body 2 is a core component in the hot-dip galvanizing production line. A connecting frame 5 is fixedly connected to the bottom of the lifting frame 4, and a rectangular connecting hole is provided on the side wall of the connecting frame 5. Furthermore, the side wall of the connecting frame 5 is provided with a disassembly mechanism 6, and a connecting block 10 is inserted into the inside of the connecting frame 5. A positioning groove is provided inside the connecting frame 5 to allow the connecting block 10 to be inserted into the inside of the connecting frame 5. A cleaning scraper 11 is fixedly connected to the bottom of the connecting block 10. The bottom of the cleaning scraper 11 contacts the outer surface of the submerged roller body 2, and the bottom of the cleaning scraper 11 cleans the outer surface of the submerged roller body 2. A servo motor 7 is fixedly connected to the side wall of the lifting frame 4, and a threaded rod 8 is fixedly connected to the output end of the servo motor 7. A rotating groove is provided on the inner side wall of the lifting frame 4. The operation of the servo motor 7 drives the threaded rod 8 to rotate inside the rotating groove. A cleaning component 9 is provided on the outer surface of the threaded rod 8.

[0019] Reference Figures 2-3The disassembly mechanism 6 includes a disassembly rod 61. The end of the disassembly rod 61 is fixedly connected to the side wall of the connecting frame 5. The end of the disassembly rod 61 is elastically connected to a disassembly block 62 through a positioning spring 63. Pushing the disassembly block 62 and squeezing the positioning spring 63 causes the positioning spring 63 to deform and reset. The rebound of the positioning spring 63 causes the disassembly block 62 to slide and reset. The disassembly block 62 is slidably connected to the outer surface of the disassembly rod 61. A limit sliding hole is opened inside the disassembly block 62 so that the disassembly block 62 can slide stably on the outer surface of the disassembly rod 61. The side wall of the connecting block 10 is provided with a disassembly hole. The disassembly block 62 passes through the connecting frame 5 and is inserted into the disassembly hole. The disassembly hole and the disassembly block 62 are used to make the connecting block 10 stably inserted into the inside of the connecting frame 5.

[0020] Reference Figures 2-4 The cleaning component 9 includes a movable block 91, which is threadedly connected to the outer surface of the threaded rod 8. The movable block 91 has a sliding hole inside, and an internal thread is provided on the inner side wall of the sliding hole. The outer surface of the threaded rod 8 is provided with an external thread that matches the size of the internal thread. The movable block 91 is slidably connected to the side wall of the lifting frame 4. A movable frame 92 is fixedly connected to the side wall of the movable block 91. The movable frame 92 is moved by the sliding of the movable block 91. A movable frame 93 is fixedly connected to the bottom of the movable frame 92. A storage frame is provided inside the movable frame 93 to collect the zinc slag after cleaning. A cleaning roller 94 is rotatably connected inside the movable frame 93. The outer surface of the cleaning roller 94 is in contact with the side wall of the cleaning scraper 11. The movable frame 93 cleans the outer surface of the cleaning scraper 11 during the movement. A cleaning block 95 is fixedly connected inside the movable frame 93. The side wall of the cleaning block 95 is in contact with the outer surface of the cleaning roller 94. The cleaning block 95 cleans the outer surface of the cleaning roller 94.

[0021] Working principle: During use, the cleaning scraper 11 is used to clean the zinc slag remaining on the outer surface of the submerged roller body 2. When the cleaning scraper 11 is damaged after long-term use and needs to be disassembled and replaced, the disassembly block 62 is pulled and the positioning spring 63 is squeezed, and the scraper 62 slides on the outer surface of the disassembly rod 61 to pull the disassembly block 62 out from the inside of the connecting block 10, thereby pulling the connecting block 10 out from the inside of the connecting frame 5. This satisfies the effect of replacing and disassembling the cleaning scraper 11. After the cleaning scraper 11 is replaced, the connecting block 10 is inserted into the inside of the connecting frame 5. Then, the push on the disassembly block 62 is released, and the rebound of the positioning spring 63 causes the disassembly block 62 to slide and reset, and then insert into the inside of the connecting block 10, improving the stable connection between the cleaning scraper 11 and the connecting frame 5. When a large amount of zinc dross remains on the surface of the cleaning scraper 11 after prolonged use, the servo motor 7 drives the threaded rod 8 to rotate. The rotation of the threaded rod 8 causes the moving block 91 to slide inside the lifting frame 4, thereby moving the moving frame 92 and the cleaning roller 94. The cleaning roller 94 rotates and cleans the outer surface of the cleaning scraper 11 during the cleaning process. While the cleaning roller 94 is rotating, the cleaning block 95 rotates and cleans the outer surface of the cleaning roller 94. The cleaned zinc dross falls to the inner bottom of the moving frame 93, which collects the cleaned zinc dross and improves the cleanliness of the cleaning roller 94 during the cleaning process.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
