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.

[0022] Please see Figures 1-4 This utility model provides a technical solution for a hot-rolled strip steel pickling device: a hot-rolled strip steel pickling device, including a pickling tank 1, and an iron removal mechanism 2 and a clamping mechanism 3 are provided on the surface of the pickling tank 1;

[0023] The iron removal mechanism 2 includes a fixed plate 201, a bracket 202, a rotating roller 203, an annular grinding plate 204, a cylinder 205, a vertical rod 206, a lifting frame 207, an upper grinding plate 208, and a receiving frame 209.

[0024] The fixed plate 201 is fixedly connected to the outer side of the pickling tank 1, the bracket 202 is fixedly connected to the top of the fixed plate 201, the rotating roller 203 is rotatably connected to the inner side of the bracket 202, the annular grinding plate 204 is detachably connected to the surface of the rotating roller 203 by a set of screws, the cylinder 205 is fixedly installed on the top of the fixed plate 201 away from the bracket 202, the upright 206 is fixedly connected to the top of the fixed plate 201 away from the cylinder 205, the lifting frame 207 is fixedly connected to the output end of the cylinder 205, the upper grinding plate 208 is detachably connected to the surface of the lifting frame 207 by another set of screws, and the receiving rack 209 is set on one side of the bracket 202.

[0025] Please refer to this carefully. Figure 2 The lifting frame 207 is slidably connected to the upright 206, and the output end of the energized cylinder 205 is used to drive the upper grinding plate 208 to move up and down through the lifting frame 207.

[0026] In this embodiment: the cylinder 205 is powered on and operated, so that the output end of the operating cylinder 205 drives the upper grinding plate 208 to move downward through the lifting frame 207.

[0027] Please refer to this carefully. Figure 4 The receiving rack 209 is located below the annular grinding plate 204 and is inclined. The receiving rack 209 is used to receive the scraped iron filings.

[0028] In this embodiment: the scraped iron filings are allowed to fall naturally onto the receiving rack 209, and the receiving rack 209 receives the scraped iron filings.

[0029] Please refer to this carefully. Figure 4 The rotating roller 203 is used to assist the annular grinding plate 204 in rotating, and the upper grinding plate 208 in the lowered state cooperates with the annular grinding plate 204 in the rotatable state to perform friction grinding on the relatively thick iron sheet on the surface of the hot-rolled strip steel.

[0030] In this embodiment: Since the rotating roller 203 can assist the annular grinding plate 204 in rotating, the upper grinding plate 208 in the descending state cooperates with the annular grinding plate 204 in the rotatable state, and under the drag of the two clamping plates 309, the relatively thick iron sheet on the surface of the hot-rolled strip steel to be pickled is rubbed and polished.

[0031] Please refer to this carefully. Figure 3 The clamping mechanism 3 includes an electric slide rail 301, an electric slide table 302, a fixed frame 303, a connecting frame 304, an electric push rod 305, a connecting rod 306, a slide groove 307, a slide bar 308, and a clamping plate 309.

[0032] An electric slide rail 301 is located on the other side of the outside of the pickling tank 1. An electric slide table 302 is slidably connected to the inner cavity of the electric slide rail 301. A fixed frame 303 is fixedly connected to the top of the electric slide table 302. A connecting frame 304 is fixedly connected to one side of the fixed frame 303. An electric push rod 305 is fixedly installed on the outside of the connecting frame 304. A connecting rod 306 is rotatably connected to the inside of the connecting frame 304 via a connecting shaft. A groove 307 is formed on the surface of the connecting rod 306. A slide bar 308 is movably connected to the inside of the groove 307. A clamping plate 309 is located at the end of the connecting rod 306.

[0033] In this embodiment: When the electric push rod 305 is powered on, its output end drives the slide rod 308 to move along the inner wall trajectory of the slide groove 307. The moving slide rod 308 transmits this force to the surfaces of the two connecting rods 306 through the two slide grooves 307. The two moving connecting rods 306 drive the two clamping plates 309 to move closer together, thus clamping the end of the hot-rolled strip steel to be pickled. At this time, the electric slide table 302 and the electric slide rail 301 are powered on, and the running electric slide table 302 drives the two connecting rods 306 and the clamping plates 309 to move axially through the fixed frame 303. The two clamping plates 309 in the axial movement state drag the clamped hot-rolled strip steel to be pickled.

[0034] Please refer to this carefully. Figure 3 The electric slide table 302 is electrically connected to the electric slide rail 301, and the slide rod 308 is connected to the output end of the electric push rod 305.

[0035] In this embodiment: the electric slide table 302 and the electric slide rail 301 are powered on and run, so that the electric slide table 302 in operation drives the two connecting rods 306 and the clamping plate 309 to move along the axis through the fixed frame 303.

[0036] Please refer to this carefully. Figure 3 The two connecting rods 306 in motion drive the two clamping plates 309 to move, and the two clamping plates 309 in the moving state are used to clamp the ends of the hot-rolled strip steel to be pickled.

[0037] In this embodiment: the two connecting rods 306 in motion drive the two clamping plates 309 to move closer to each other, and the two clamping plates 309 in the close-moving state clamp the end of the hot-rolled strip steel to be pickled.

[0038] Working principle: First, the hot-rolled strip steel to be pickled is placed in the clamping area of ​​the annular grinding plate 204 and the upper grinding plate 208. At this time, the cylinder 205 is powered on and operated, so that the output end of the cylinder 205 drives the upper grinding plate 208 to move downward through the lifting frame 207. The upper grinding plate 208 and the annular grinding plate 204 clamp the hot-rolled strip steel to be pickled. Then, the electric push rod 305 is powered on and operated, so that the output end of the electric push rod 305 drives the slide rod 308 to move along the inner wall trajectory of the slide groove 307. The slide rod 308 in the moving state transmits this moving force to the surfaces of the two connecting rods 306 through the two slide grooves 307. The two connecting rods 306 in the moving state drive the two clamping plates 309 to move closer together. The two clamping plates 309 in the moving state clamp the end of the hot-rolled strip steel to be pickled.

[0039] At this point, the electric slide table 302 and the electric slide rail 301 are powered on and run. The electric slide table 302 in operation drives the two connecting rods 306 and the clamping plate 309 to move axially through the fixed frame 303. The two clamping plates 309 in the axial movement state drag the hot-rolled strip steel to be pickled. Since the rotating roller 203 can assist the annular grinding plate 204 to rotate, the upper grinding plate 208 in the descending state cooperates with the rotatable annular grinding plate 204. Under the drag of the two clamping plates 309, the thicker iron sheet on the surface of the hot-rolled strip steel to be pickled is rubbed and ground. The scraped iron filings naturally fall onto the receiving frame 209. After the hot-rolled strip steel to be pickled is ground, the clamping of the hot-rolled strip steel to be pickled is released, allowing the hot-rolled strip steel to be pickled to fall naturally into the pickling tank 1. The hot-rolled strip steel to be pickled is then pickled and dissolved by the acid solution. Thus, the pickling efficiency of the hot-rolled strip steel by the above structure is effectively improved.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
