Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In this embodiment, as Figure 1 and Figure 2 As shown, a hot-rolled steel plate leveling and rust removal device includes a frame 1. The device includes a feeding unit 2, a straightening unit 3 and a mechanical rust removal unit 4 integrated on the same rigid frame 1 along the steel plate traveling direction. The straightening unit 3 is mounted on the frame 1 and is used to straighten the steel plate; The mechanical rust removal unit 4 is located downstream of the straightening unit 3 and is used to remove rust from the surface of the steel plate. The mechanical rust removal unit 4 includes a slide 41, two slide plates 42, a grinding assembly 43, and a drive assembly 44. The slide 41 is fixed to the frame 1 by brackets 411 on both sides. The two slide plates 42 are slidably connected to the slide 41 and are symmetrically distributed vertically. The grinding assembly 43 includes multiple rust removal parts 431, which are symmetrically installed on the upper and lower slide plates 42. The drive assembly 44 is connected to the slide plates 42 and is used to drive the upper and lower slide plates 42 to perform synchronous reciprocating linear motion.

[0022] Thus, the slide block 41 is installed in the position of use by the bracket 411. When the steel plate passes through the grinding assembly 43, the drive assembly 44 is activated. The drive assembly 44 drives the two slide plates 42 to move on the slide block 41. The two slide plates 42 drive the grinding assembly 43 to move along both sides of the steel plate to remove rust from both sides of the steel plate.

[0023] Specifically, the slide block 41 is machined with a protrusion that matches the slide plate 42. The cross section of the protrusion is arc-shaped and can be embedded into the slot of the slide plate 42. The two slide plates 42 are designed to install multiple sets of grinding components 43. The multiple sets of grinding components 43 are symmetrically distributed on both sides of the steel plate to grind and remove rust on both sides of the steel plate at the same time, thereby increasing the rust removal efficiency. In addition, the bracket 411 vertically fixes the slide 41 to the base plate 12 of the frame 1, and the two slide plates 42 are inserted into the grooves 11 of the frame 1.

[0024] In some embodiments, such as Figure 3 As shown, the rust removal component 431 includes a cylinder body 431a, a piston rod 431b, an elastic element 431d, and a grinding wheel 432; the cylinder body 431a is fixed on the slide plate 42; the piston rod 431b is movably disposed in the cylinder body 431a, and its extended end is connected to the grinding wheel 432; the elastic element 431d is housed in the cylinder body 431a, and its two ends abut against the piston rod 431b and the cylinder body 431a respectively, providing elastic pressure to the grinding wheel 432 toward the steel plate surface.

[0025] Specifically, the cylinder 431a is designed with eight cylinders symmetrically distributed on the two slide plates 42. The elastic element 431d can be a compression spring or other elastic elements. The grinding wheel 432 can be a grinding wheel or a wire roller. The elastic element 431d provides elastic pressure to the grinding wheel 432 towards the steel plate surface, so that the grinding wheel 432 fits tightly with the steel plate. The number of cylinder blocks 431a used can be installed according to specific usage requirements.

[0026] In some embodiments, such as Figure 2 As shown, the drive assembly 44 includes a dual-head motor 441, two discs 442 and two strips 443; the dual-head motor 441 is fixedly mounted on the end of the slide block 41 away from the slide plate 42; the two discs 442 are respectively fixedly mounted on the two output shafts of the dual-head motor 441; one end of the strip 443 is hinged to the eccentric position of the disc 442, and the other end is hinged to the slide plate 42.

[0027] Specifically, the dual-head motor 441 has two output shafts. The dual-head motor 441 is a technology known to those skilled in the art, and its specific model can be selected according to the usage requirements. The disc 442 is fixedly connected to the output shaft of the dual-head motor 441. One end of the strip 443 is hinged to the eccentric position of the disc 442, and the other end is hinged to the slide plate 42. When the disc 442 rotates, the strip 443 drives the slide plate 42 to move along the slide base 41.

[0028] In some embodiments, such as Figure 2 As shown, the straightening unit 3 includes a frame 31, a hydraulic cylinder 32, and a pressure plate 33; the frame 31 is mounted on the frame 1; the cylinder body of the hydraulic cylinder 32 is mounted on the frame 31, and its extension rod extends downward; the pressure plate 33 is connected to the bottom end of the extension rod of the hydraulic cylinder 32. Specifically, the frame 31 is mounted on the frame 1 so that the hydraulic cylinder 32 is set perpendicular to the support plate 13. The pressure plate 33 can be designed to be circular or other shapes. The steel plate is flattened by the cooperation of the pressure plate 33 and the support plate 13.

[0029] In some embodiments, such as Figure 4 As shown, the frame 31 is slidably connected to the frame 1 via a sliding member 34 provided at its bottom; the sliding member 34 includes a slide rail 341, a sliding housing 342 and a positioning pin 343, the positioning pin 343 being used to lock the relative position of the slide rail 341 and the sliding housing 342. Specifically, the sliding component 34 is designed with two sets. The sliding shell 342 moves along the outer wall of the slide rail 341. The outer wall of the positioning pin 343 is machined with threads, and the top of the slide rail 341 is machined with a threaded hole that matches the positioning pin 343. In addition, by changing the relative position between the slide rail 341 and the slide housing 342, the slide housing 342 drives the frame 31 to move, thereby changing the position of the frame 31 at the top of the support plate 13.

[0030] In some embodiments, such as Figure 4 As shown, the cylinder body of the hydraulic cylinder 32 is mounted on the mounting plate 35, which is movably mounted on the frame 31. A guide rod 351 is provided in the mounting plate 35. One end of the guide rod 351 is connected to the frame 31, and the other end extends into the through hole of the mounting plate 35. Specifically, the top of the frame 31 has a groove that matches the mounting plate 35. The guide rod 351 is used to constrain the movement direction of the mounting plate 35. A locking element is also designed between the guide rod 351 and the mounting plate 35 to lock the position of the mounting plate 35 on the guide rod 351. (The locking element is installed according to the actual situation, for example, it is installed in the mounting plate 35 by bolts. The bolts are rotated to abut against the guide rod 351 to lock the position of the mounting plate 35 on the guide rod 351.)

[0031] In some embodiments, such as Figure 1 As shown, the feed unit 2 is located at the front end of the inlet of the straightening unit 3 and is used to push the steel plate to move on the table of the frame 1; The feed unit 2 includes a servo motor 21, a threaded drive shaft 22, a connecting seat 23, and a top frame 24; a groove 11 is provided on the table surface of the frame 1; the threaded drive shaft 22 is rotatably connected in the groove 11; the servo motor 21 is fixedly installed on the frame 1, and its output end is connected to the input end of the threaded drive shaft 22 to drive its rotation; the connecting seat 23 is threadedly engaged with the threaded drive shaft 22 through the internal threaded hole at its bottom; the top frame 24 is fixedly installed on the top of the connecting seat 23.

[0032] Specifically, the servo motor 21 is connected to the threaded drive shaft 22 via a coupling. The threaded drive shaft 22 rotates in the groove 11 via a bearing (the groove 11 is specifically opened in the support plate 13). The outer circumference of the connecting seat 23 is adapted to the groove 11. At this time, the groove 11 is used to constrain the lateral movement of the connecting seat 23. The top frame 24 is detachably installed on the connecting seat 23. In addition, the top frame 24 can be lengthened to allow the steel plate to move a longer distance.

[0033] In some embodiments, such as Figure 1 As shown, the top frame 24 has a U-shaped structure; Specifically, the top frame 24 adopts a U-shaped design, which allows the top frame 24 to move along the outer periphery of the pressure plate 33 (the size of the U-shaped opening is larger than the size of the pressure plate 33) to push the steel plate onto another support plate 13.

[0034] In some embodiments, such as Figure 5As shown, the frame 1 includes a base plate 12 and two support plates 13. The two support plates 13 are symmetrically fixed on the upper surface of the base plate 12, and there is a gap between the two support plates 13 to form a gap 13a. The mechanical rust removal unit 4 is located in the gap 13a. Specifically, the base plate 12 supports the overall mechanism, and there are two support plates 13. The gap 13a between the two support plates 13 is used to install the grinding component 43. The width of the gap 13a is adapted to the width of the slide plate 42.

[0035] In some embodiments, such as Figure 3 As shown, the piston rod 431b has a limiting protrusion 431b-1 at the top end. The size of the limiting protrusion 431b-1 is larger than the outlet diameter of the cylinder 431a, which is used to prevent the piston rod 431b from coming out of the cylinder 431a. Specifically, the limiting protrusion 431b-1 is located in the inner cavity of the cylinder 431a. The limiting protrusion 431b-1 abuts against the elastic element 431d. The design of the limiting protrusion 431b-1 prevents the piston rod 431b from coming out of the cylinder 431a.

[0036] The working principle of this application is illustrated below with a preferred embodiment: The steel plate to be processed is placed on the support plate 13, and then the servo motor 21 is started. The servo motor 21 drives the threaded drive shaft 22 to rotate through the coupling. The threaded drive shaft 22 drives the connecting seat 23 to move. The connecting seat 23 drives the top frame 24 to move along the top surface of the support plate 13. As the top frame 24 moves, the steel plate is pushed into the frame 31. Then, the hydraulic cylinder 32 is activated. The extended end of the hydraulic cylinder 32 drives the pressure plate 33 to move down. The pressure plate 33, together with the support plate 13, presses the steel plate flat. In actual use, the mounting plate 35 is moved on the outer wall of the guide rod 351. The mounting plate 35 drives the hydraulic cylinder 32 to move, so as to change the pressing position of the pressure plate 33, thereby flattening different positions of the steel plate. The steel plate moves continuously on the support plate 13 between the slide plates 42. Under the action of the elastic element 431d, the piston rod 431b is pushed to move closer to the steel plate. The piston rod 431b drives the grinding wheel 432 to fit against the surface of the steel plate. Then, the motor 441 is started. The two output shafts of the motor 441 drive the disc 442 to rotate. As the disc 442 rotates, it drives the strip 443 to move. The strip 443 pulls the slide plate 42 to move on the slide block 41. Then, the two slide plates 42 drive multiple sets of grinding wheels 432 to move along the outer wall of the steel plate to remove rust.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
