Description

Technical Field

[0001] This utility model relates to the field of strip steel descaling technology, and more specifically to a strip steel descaling device. Background Technology

[0002] Iron oxide scale on the surface of steel strip is easily affected by weather conditions, temperature, and other factors, leading to unstable detection signals. This problem causes deviations in the timing of flying shear operation, which may result in premature or delayed shearing. Steel strip descaling devices have emerged to address this issue. By using descaling devices, these oxide scales can be effectively loosened and broken, thereby improving the efficiency of subsequent descaling processes.

[0003] In today's industrial production, especially on strip steel production lines, most existing strip steel descaling devices use anchor chain devices for descaling operations. However, these anchor chain devices have certain limitations in practical applications. From the perspective of descaling effect, this design may lead to residual scale fragments. When the anchor chain device contacts the scale on the strip steel surface and performs the descaling operation, due to its structural characteristics and limitations in its operating method, it is difficult to completely remove the scale, inevitably leaving residual scale fragments. These residual fragments not only affect the quality of the strip steel surface but may also pose potential hazards to subsequent production processes.

[0004] Moreover, what's even more troublesome is that after the existing equipment completes the scale breaking operation, the already broken scale fragments may be blown up by factors such as airflow. These blown-up scale fragments will float in the air and eventually fall onto the strip steel in the production process. This situation directly leads to the problem of scale covering the surface of the strip steel again.

[0005] To address the aforementioned problems, this application provides a strip steel descaling device. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a strip steel descaling device to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a strip steel scale breaking device, including a main component and a buffer component installed on the main component, wherein a scale breaking component is installed on the buffer component, and an air jet component and a screen component are installed on the main component;

[0008] Preferably, the main component includes a base plate, an upper plate, connecting columns, sliding sleeves, adjusting threads, and nuts. The upper plate is positioned above the base plate, the sliding sleeves are positioned at the four corners of the upper plate and rotatably sleeved with them, the connecting columns are fixedly installed at the four corners of the base plate and movably sleeved with the sliding sleeves, wherein adjusting threads are provided on two diagonally opposite connecting columns, and the nuts are threadedly sleeved on the connecting columns with nuts and fixedly connected to the corresponding sliding sleeves. When the adjusting nuts are rotated, the thread engagement between the nuts and the adjusting threads causes the sliding sleeves fixedly connected to them to press down, thereby causing the upper plate to move down.

[0009] Preferably, the buffer assembly includes a buffer sleeve, a transmission arm, a buffer spring, and a main crossbeam. There are two buffer sleeves, which are fixedly installed on the front and rear sides of the bottom of the upper plate. The transmission arm is movably engaged with the buffer sleeve, and the main crossbeam is fixedly installed between the two transmission arms. When the main crossbeam is subjected to upward pressure, the buffer spring is driven by the transmission arm to provide buffering.

[0010] Preferably, the scale-breaking assembly includes a rotary motor, a first gear, a second gear, a rotary roller, a sprocket, a limiting frame, a chain, a synchronous steel bar, and a scale-breaking scraper. The rotary motor is fixedly installed on the right side of the main beam. The rotary motor's drive shaft is fixedly sleeved on the first gear. The second gear is fixedly sleeved on the rotary roller and meshes with the first gear. Sprockets are fixedly sleeved at both ends of the rotary roller. The rotary motor's drive shaft drives the first gear, which in turn drives the rotary roller via the second gear, thereby causing the rotary roller and the sprockets fixedly sleeved at both ends to rotate along their own axis. One end of the limiting frame is fixedly installed on the side wall of the limiting frame, and the other end is rotatably sleeved on the rotary roller. Chains are wound and meshed on the sprockets on the left and right sides of the main beam. Synchronous steel bars are fixedly installed at the chain links on the front and rear sides. The scale-breaking scraper is fixedly installed on the synchronous steel bars. The meshing action between the sprockets on both sides and the limiting frame drives the chain wound between the sprockets on both sides, thereby causing the synchronous steel bars fixedly installed at the chain links to move the scale-breaking scraper fixedly installed thereon.

[0011] Preferably, the jet assembly includes a nozzle, a high-pressure air pipe, and a retainer, wherein the retainer is fixedly installed on the front and rear sides of the upper end of the base plate, the nozzle is fixedly installed on the retainer, and the rear end of the nozzle is fixedly connected to the high-pressure air pipe.

[0012] Preferably, the mesh assembly includes a first hinge, a second hinge, a scale-blocking mesh, a locking rod, and a limiting block. The first hinge is fixedly installed on the right side of the upper plate. One end of the second hinge is hinged to the first hinge, and the other end is fixedly installed on the scale-blocking mesh. The locking rod is fixedly installed on the end of the scale-blocking mesh away from the second hinge. The limiting block is fixedly installed on the front and rear sides of the upper end of the bottom plate. The upper side of the limiting block is engaged with the locking rod. At this time, the scale-blocking mesh and the second hinge are rotated along the hinge axis between the first hinge and the second hinge until the locking rod is engaged with the limiting block.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] When using the device, the strip steel passes over the bottom plate. The rotary motor inside the descaling assembly drives the descaling scraper to move. The overall up and down movement of the descaling assembly can be controlled according to the thickness of the strip steel, so that the descaling scraper presses tightly against the strip steel, thereby performing the descaling operation. This design can effectively remove the iron oxide scale on the surface of the steel plate and improve product quality. At the same time, after descaling, the air jet assembly and the partition assembly can effectively remove the fallen scale fragments and prevent the blown scale fragments from falling back onto the strip steel.

[0022] Reference Figure 1 and Figure 2 The main component 1 includes a base plate 101, an upper plate 102, a connecting column 103, a sliding sleeve 104, an adjusting thread 105, and a nut 106.

The connecting column 103 is fixedly installed at the four corners of the base plate 101 and movably sleeved with the sliding sleeve 104. The two diagonally opposite connecting columns 103 are provided with adjusting threads 105. The nut 106 is threadedly sleeved on the connecting column 103 with the nut 106 and is fixedly connected to the corresponding sliding sleeve 104. When the adjusting nut 106 is rotated, the thread engagement between the nut 106 and the adjusting thread 105 causes the sliding sleeve 104 fixedly connected to it to press down, thereby causing the upper plate 102 to move down.

[0023] Reference Figure 2 and Figure 3 The buffer assembly 2 includes a buffer sleeve 201, a transmission arm 202, a buffer spring 203, and a main crossbeam 204.

The second gear 303 is fixedly sleeved on the rotary roller 304 and meshes with the first gear 302. Sprockets 305 are fixedly sleeved at both ends of the rotary roller 304. At this time, the drive shaft of the rotary motor 301 drives the first gear 302, and through the second gear 303, drives the rotary roller 304, thereby driving the rotary roller 304 and the sprockets fixedly sleeved on the first gear 305. The sprockets 305 at both ends rotate around their own axis; one end of the limiting frame 306 is fixedly installed on the side wall of the limiting frame 306, and the other end is rotatably sleeved with the rotating roller 304. Chains 307 are wound and meshed on the sprockets 305 on the left and right sides of the main beam 204.

The scale-breaking scraper 309 is fixedly installed on the synchronous steel bars 308. At this time, the chain 307 wound between the sprockets 305 on both sides is driven by the meshing action between the sprockets 305 on both sides and the limiting frame 306. Then, the synchronous steel bars 308 fixedly installed at the connection of the chains 307 drive the scale-breaking scraper 309 fixedly installed on them to move.

[0025] Reference Figure 1 and Figure 2 The jet assembly 4 includes a nozzle 401, a high-pressure air pipe 402 and a fixture 403.

[0026] Reference Figure 1 The mesh assembly 5 includes a first hinge 501, a second hinge 502, a scale-blocking mesh 503, a locking rod 504, and a limiting block 505. The first hinge 501 is fixedly installed on the right side of the upper plate 102. One end of the second hinge 502 is hinged to the first hinge 501, and the other end is fixedly installed on the scale-blocking mesh 503. The locking rod 504 is fixedly installed on the end of the scale-blocking mesh 503 away from the second hinge 502. The limiting block 505 is fixedly installed on the front and rear sides of the upper end of the bottom plate 101. The upper side of the limiting block 505 is engaged with the locking rod 504. At this time, the scale-blocking mesh 503 and the second hinge 502 are rotated along the hinge axis between the first hinge 501 and the second hinge 502 until the locking rod 504 is engaged with the limiting block 505.

[0027] The working principle of this utility model is as follows: When using the device, the strip steel passes over the base plate 101. The drive shaft of the rotary motor 301 drives the first gear 302, which in turn drives the rotary roller 304 through the second gear 303. This drives the rotary roller 304 and the sprockets 305 fixedly sleeved at both ends to rotate around their own axis. The meshing action between the sprockets 305 on both sides and the limiting frame 306 drives the chain 307 wound between the sprockets 305 on both sides. This causes the synchronous steel strip 308 fixedly installed at the link of the chain 307 to move the scale-breaking scraper 309 fixedly installed thereon. At this time, the adjusting nut 106 is rotated according to the thickness of the strip steel. The interaction between the nut 106 and the adjusting thread 105... The threaded engagement causes the sliding sleeve 104, which is fixedly connected to it, to press down, which in turn causes the upper plate 102 and the scale-breaking assembly 3 located below to press down as a whole, until the scale-breaking scraper 309 located below presses the strip steel tightly. Then, the scale-breaking scraper 309 driven by the threaded engagement causes the strip steel to be scaled. At the same time, when the scaled strip steel passes through the jet assembly 4, the nozzles 401 located on the front and rear sides guide air through the high-pressure air pipes 402 to remove the broken scales on the strip steel. At the same time, the scale-blocking mesh 503 and the second hinge 502 rotate along the hinge axis between the first hinge 501 and the second hinge 502 until the locking rod 504 is locked on the limiting block 505 to prevent the blown broken scales from falling back onto the strip steel.
