Description

Technical Field

[0001] This utility model relates to the field of submerged roller technology, specifically a submerged roller scraper mechanism. Background Technology

[0002] In existing hot-dip galvanizing production lines, the zinc pot submerged roller is a crucial roller in the galvanizing process that comes into direct contact with the strip steel. Due to the complex composition and high temperature of the molten zinc in the zinc pot, the operating conditions of the submerged roller are extremely harsh, especially the large amount of zinc dross generated by the incorporation of iron. This zinc dross adheres to the submerged roller inside the zinc pot. Therefore, existing submerged rollers are generally equipped with a scraper mechanism to facilitate cleaning of the roller surface. However, the existing scraper structure is simple and its effect is limited. Generally, it can only clean submerged rollers of a fixed size. Furthermore, the existing scrapers are usually connected by bolts, but after use, impurities and foreign objects often adhere to the surface of the bolts. This means that when disassembling and replacing the scraper, it is often necessary to first clean the bolt surface before using tools to disassemble the bolts and scraper. The disassembly process is cumbersome and affects the use of the submerged roller. Utility Model Content

Detailed Implementation

[0032] 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.

[0033] Example 1

[0034] Please see Figure 1-7 In this embodiment of the utility model, a submerged roller scraper mechanism includes: a mounting plate 100 and a scraping mechanism 200. A fixing plate 110 is provided at the bottom of the mounting plate 100, and the fixing plate 110 is provided with a connecting hole 111 and two sliding grooves 112. Two connecting arms 120 are fixedly connected to the fixing plate 110, and a submerged roller body 121 is rotatably connected between the bottoms of the two connecting arms 120. The scraping mechanism 200 is provided on the fixing plate 110.

[0035] Specifically, the scraping mechanism 200 facilitates the scraping and cleaning of the surface of the submerged roller body 121, and the scraping mechanism 200 is applicable to submerged roller bodies 121 of different sizes, making it more convenient to use.

[0036] like Figure 3-7As shown, in this embodiment, the scraping mechanism 200 includes: a support plate 210, a movable shell 220, and a scraper body 230. The support plate 210 is disposed on the top of the fixed plate 110, and a second connecting hole 211 is provided on the support plate 210. An adjustment component is provided on the top of the support plate 210. The top of the movable shell 220 passes through the first connecting hole 111 and the second connecting hole 211 and is located on the top of the support plate 210. A moving component is provided on the outside of the movable shell 220, and a limiting component is provided on the movable shell 220. The scraper body 230 is disposed at the bottom of the movable shell 220, and a connecting plate 231 is fixedly connected to the scraper body 230. The connecting plate 231 is inserted into the bottom of the movable shell 220. Two limiting grooves 232 are provided on the connecting plate 231. The moving component includes two connecting seats 260. Both connecting seats 260 are fixedly connected to the support plate 210, and a screw 261 is rotatably connected between the two connecting seats 260. The outside of the screw 261 is connected to a transmission connection. There is a movable block 262, one end of which is fixedly connected to the movable housing 220, and the bottom of the movable block 262 contacts the top of the support plate 210. A motor 263 is mounted on one end of a screw 261, the bottom of which is fixedly connected to the support plate 210, and the output end of which is fixedly connected to one end of the screw 261. The limiting assembly includes a support plate 270 and a second motor 280. The support plate 270 is fixedly connected to the top of the interior of the movable housing 220. The support plate 270 rotates upwards... A bidirectional lead screw 271 is dynamically connected, and both ends of the bidirectional lead screw 271 are screwed to a movable plate 272. Both movable plates 272 are slidably connected to the inside of the movable shell 220. The bottom of both movable plates 272 is fixedly connected to a limit block 273, and the two limit blocks 273 are slidably connected to two limit grooves 232 respectively. The second motor 280 is fixedly connected to the movable shell 220, and the output end of the second motor 280 passes through the side wall of the movable shell 220 and is fixedly connected to one end of the bidirectional lead screw 271.

[0037] In this embodiment, the limiting component, in conjunction with the two limiting grooves 232, facilitates the limiting and fixing of the connecting plate 231 and the scraper body 230. This allows the scraper body 230 to easily scrape away foreign matter from the surface of the submerged roller body 121 at the corresponding position. By starting the motor 263, the screw 261 rotates, and the bottom of the moving block 262 contacts the bearing plate 210, thus limiting the movement of the moving block 262. Consequently, when the screw 261 rotates, the moving block 262, the moving shell 220, and the scraper body 230 move. The scraper body 230 can be adjusted... The position of 30 allows the scraper body 230 to scrape foreign objects from different positions on the surface of the submerged roller body 121, making it more convenient to use. When the scraper body 230 is damaged, the motor 280 is started to rotate forward, which causes the bidirectional lead screw 271 to rotate forward, thereby causing the two moving plates 272 and the two limiting blocks 273 to move in opposite directions. When one end of the limiting block 273 separates from the insertion point of the limiting groove 232, it is easy to remove the scraper body 230 and the connecting plate 231, which facilitates the quick replacement of the damaged scraper body 230, making it more convenient to use.

[0038] Example 2

[0039] Based on Embodiment 1, in order to adjust the positions of the support plate 210, the movable shell 220 and the scraper body 230 so that the scraping mechanism 200 can be adapted to submerged roller bodies 121 of different sizes.

[0040] like Figure 3-7 As shown, in this embodiment, the adjustment component includes: a support frame 240, a fixed frame 250, and a digital hydraulic cylinder 290. The bottom of the support frame 240 is fixedly connected to the fixed plate 110, the top of the support frame 240 is fixedly connected to the mounting plate 100, the bottom of the fixed frame 250 is fixedly connected to the support plate 210, the digital hydraulic cylinder 290 is fixedly connected to the support frame 240, and the output end of the digital hydraulic cylinder 290 is fixedly connected to the fixed frame 250. Both ends of one side of the fixed frame 250 are fixedly connected to telescopic plates 251, and one end of each of the two telescopic plates 251 is fixedly connected to the support frame 240. The bottom of both ends of the support plate 210 is rotatably connected to multiple rotating balls 212, and the multiple rotating balls 212 are slidably connected to the interior of two sliding grooves 112 respectively.

[0041] In practical implementation, two sliding grooves 112 and multiple rotating balls 212 are used in conjunction to facilitate the support and limiting of the bearing plate 210. The telescopic plate 251 can also provide auxiliary support and limiting of the fixed frame 250 and the bearing plate 210. By activating the digital hydraulic cylinder 290, the fixed frame 250 and the bearing plate 210 are moved, thereby adjusting the horizontal position of the moving component, the limiting component, the moving shell 220, and the scraper body 230. This allows the scraping mechanism 200 to be applicable to submerged roller bodies 121 of different sizes. When the scraper body 230 is worn but not damaged, and only the scraping and cleaning effect is affected, the digital hydraulic cylinder 290 can be used to fine-tune the position of the scraper body 230, so that the scraper body 230 fits more tightly with the submerged roller body 121, thereby ensuring the cleaning effect of the scraper body 230 and improving the practicality of the submerged roller scraper mechanism.
