Description

Technical Field

[0001] This utility model relates to the technical field of leveling devices, and in particular to a metal coil leveling device. Background Technology

[0002] In modern industrial production, metal coils, as a basic material, are widely used in various fields such as automobile manufacturing, aerospace, construction, and electronics. During production, transportation, and storage, metal coils inevitably undergo various deformations. These deformations severely affect the quality of the metal coils and the precision of subsequent processing; therefore, leveling treatment of the metal coils is necessary.

[0003] Existing leveling devices apply repeated bending stress to metal sheets using multiple sets of vertically arranged rollers, causing plastic deformation within the material to eliminate existing internal stress and shape defects, thereby obtaining a flat sheet. However, the roller distance adjustment of existing leveling devices is inconvenient, the traditional mechanical manual adjustment method is cumbersome, and the roller surface is difficult to clean. Impurities such as oxide scale and metal shavings generated during processing are easily attached to the rollers, affecting the leveling of the coiled material. Utility Model Content

[0004] The purpose of this invention is to provide a metal coil leveling device to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A metal coil leveling device includes a mounting frame, a lower leveling roller rotatably connected inside the mounting frame, an adjusting frame fixedly connected to the top of the mounting frame, a mounting plate slidably connected inside the adjusting frame, an upper leveling roller rotatably connected to the inner side of the mounting plate, a movable plate on the top of the upper leveling roller, a cleaning mechanism between the movable plate and the upper leveling roller, the cleaning mechanism including a motor, a lead screw drivenly connected to the output end of the motor, a moving block threadedly connected to the surface of the lead screw, a fixing bolt threadedly connected to one side of the moving block, and a cleaning block threadedly connected to one end of the fixing bolt, the curvature of the bottom surface of the cleaning block being adapted to the upper leveling roller.

[0007] In some embodiments, a limiting groove is formed at the bottom of the movable plate, a limiting block is slidably connected to the inner sidewall of the limiting groove, and the bottom of the limiting block is fixedly connected to the movable block.

[0008] In some embodiments, a hydraulic cylinder is fixedly connected to the top of the adjusting frame, the telescopic end of the hydraulic cylinder is fixedly connected to the movable plate, a connecting block is fixedly connected to the bottom of the movable plate, the bottom of the connecting block is fixedly connected to the mounting plate, T-shaped blocks are fixedly connected to both ends of the mounting plate, a strip groove is provided on both ends of the adjusting frame near the mounting plate, the inside of the strip groove is slidably connected to the T-shaped block, and the inner side of the mounting plate is rotatably connected to the upper leveling roller.

[0009] In some embodiments, a wear-resistant rubber layer is adhered to the contact surface of the cleaning block with the upper leveling roller.

[0010] In some embodiments, the two ends of the mounting plate are integrally formed with the T-shaped block, and the cross-section of the strip groove is T-shaped and adapted to the T-shaped block.

[0011] In some embodiments, the cleaning block and the moving block are connected by fixing bolts.

[0012] In some embodiments, a parking opening is provided on one side of the cleaning block, and the height of the parking opening is three times the thickness of the cleaning block.

[0013] In some embodiments, a rotating shaft is fixedly connected to the end of the lead screw away from the motor, and the outer ring of the rotating shaft is fixedly connected to the connecting block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When it is necessary to clean the dirt on the surfaces of the lower and upper leveling rollers, the motor starts and transmits power to the lead screw, causing the lead screw to rotate. This, in turn, drives the threaded moving block to move laterally. The cleaning block moves with the moving block to clean the surface of the upper leveling roller. Because the bottom curvature of the cleaning block is adapted to the upper leveling roller, it can better fit the surface of the upper leveling roller, achieving effective cleaning. Timely cleaning of dirt on the surface of the upper leveling roller can prevent dirt from forming a friction medium between the upper leveling roller and the metal coil, reducing wear on the upper leveling roller and the metal coil, and extending the service life of the upper leveling roller.

[0016] Second: When the position of the upper leveling roller needs to be adjusted, the hydraulic cylinder extends and retracts, causing the movable plate to move up and down. The movable plate moves the mounting plate through the connecting block. The T-shaped blocks at both ends of the mounting plate slide in the strip groove of the adjustment frame, so that the mounting plate moves stably, thereby driving the upper leveling roller to adjust its position to adapt to the leveling work of metal coils of different thicknesses.

They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Given that the existing leveling devices have inconvenient roller distance adjustment, the traditional mechanical manual adjustment method is cumbersome to operate, and the roller surface is difficult to clean, impurities such as oxide scale and metal shavings generated during processing are easy to adhere to the roller and affect the leveling of the rolled material.

[0026] like Figure 1-4 As shown, this utility model embodiment provides a metal coil leveling device, including a mounting frame 1. A lower leveling roller 101 is rotatably connected inside the mounting frame 1. An adjusting frame 102 is fixedly connected to the top of the mounting frame 1. A mounting plate 203 is slidably connected inside the adjusting frame 102. An upper leveling roller 103 is rotatably connected to the inner side of the mounting plate 203. A movable plate 201 is provided on the top of the upper leveling roller 103. A cleaning mechanism 3 is provided between the movable plate 201 and the upper leveling roller 103. The cleaning mechanism 3 includes a motor 301. A lead screw 302 is drivenly connected to the output end of the motor 301. A moving block 303 is threadedly connected to the surface of the lead screw 302. A fixing bolt 305 is threadedly connected to one side of the moving block 303. A cleaning block 304 is threadedly connected to one end of the fixing bolt 305. The curvature of the bottom surface of the cleaning block 304 is adapted to the upper leveling roller 103.

[0027] The existing leveling device uses a motor to drive the belt to rotate the lower leveling roller 101 and the upper leveling roller 103 to achieve the leveling of metal coils. When the metal coil passes through the gap between the rollers, the alternating rotation of the rollers causes plastic deformation to the bent metal coil, gradually eliminating the uneven stress inside the material and the surface wavy defects, and finally outputting a flat metal sheet.

[0028] When it is necessary to clean the dirt on the surfaces of the lower leveling roller 101 and the upper leveling roller 103, the motor 301 starts and transmits power to the lead screw 302, causing the lead screw 302 to rotate. This, in turn, drives the threaded moving block 303 to move laterally. The cleaning block 304 moves with the moving block 303 to clean the surface of the upper leveling roller 103. Since the bottom curvature of the cleaning block 304 is adapted to the upper leveling roller 103, it can better fit the surface of the upper leveling roller 103, achieving effective cleaning. Timely cleaning of dirt on the surface of the upper leveling roller 103 can prevent dirt from forming a friction medium between the upper leveling roller 103 and the metal coil, reducing wear between the upper leveling roller 103 and the metal coil, and extending the service life of the upper leveling roller 103.

[0029] Furthermore, a limiting groove 2011 is provided at the bottom of the movable plate 201, and a limiting block 307 is slidably connected to the inner side wall of the limiting groove 2011. The bottom of the limiting block 307 is fixedly connected to the movable block 303.

[0030] When the motor 301 drives the lead screw 302 to rotate and the moving block 303 moves, the limiting block 307 slides within the limiting groove 2011. The side wall of the limiting groove 2011 restricts the limiting block 307, ensuring that the limiting block 307 can only move along the length direction of the limiting groove 2011. This, in turn, ensures that the moving block 303 also moves stably along a straight line. Consequently, the cleaning block 304 stably cleans the surface of the upper leveling roller 103, enabling the cleaning work to be carried out accurately and efficiently, thus improving the cleaning quality and efficiency.

[0031] Furthermore, a hydraulic cylinder 2 is fixedly connected to the top of the adjusting frame 102, the telescopic end of the hydraulic cylinder 2 is fixedly connected to the movable plate 201, a connecting block 202 is fixedly connected to the bottom of the movable plate 201, the bottom of the connecting block 202 is fixedly connected to the mounting plate 203, T-shaped blocks 204 are fixedly connected to both ends of the mounting plate 203, and strip grooves 205 are opened at both ends of the adjusting frame 102 near the mounting plate 203. The inside of the strip grooves 205 is slidably connected to the T-shaped blocks 204, and the inner side of the mounting plate 203 is rotatably connected to the upper leveling roller 103.

[0032] When the position of the upper leveling roller 103 needs to be adjusted, the hydraulic cylinder 2 extends and retracts, causing the movable plate 201 to move up and down. The movable plate 201 drives the mounting plate 203 to move through the connecting block 202. The T-shaped blocks 204 at both ends of the mounting plate 203 slide in the strip groove 205 of the adjusting frame 102, so that the mounting plate 203 moves stably, thereby driving the upper leveling roller 103 to adjust its position to adapt to the leveling work of metal coils of different thicknesses.

[0033] Furthermore, a wear-resistant rubber layer is adhered to the contact surface between the cleaning block 304 and the upper leveling roller 103.

[0034] The cleaning block 304 has a wear-resistant rubber layer adhering to the contact surface with the upper leveling roller 103. When the cleaning block 304 cleans the surface of the upper leveling roller 103, the wear-resistant rubber layer contacts the surface of the upper leveling roller 103, which plays a buffering and protective role, reducing the wear caused by direct metal-to-metal contact. At the same time, the wear-resistant rubber layer can better fit the surface of the upper leveling roller 103, so that the cleaning block 304 can more effectively clean the impurities on the surface of the upper leveling roller 103.

[0035] Furthermore, the two ends of the mounting plate 203 are integrally formed with the T-shaped block 204, and the cross section of the strip groove 205 is T-shaped and is adapted to the T-shaped block 204.

[0036] This ensures that the mounting plate 203 will not shake or get stuck during movement, making the position adjustment of the upper leveling roller 103 more stable.

[0037] Furthermore, the cleaning block 304 and the moving block 303 are connected by fixing bolts 305.

[0038] The cleaning block 304 and the moving block 303 are connected by a fixing bolt 305. When the cleaning block 304 needs to be replaced, the replacement can be completed simply by turning the fixing bolt 305. The operation is simple and convenient.

[0039] Furthermore, a parking opening 206 is provided on one side of the cleaning block 304, and the height of the parking opening 206 is three times the thickness of the cleaning block 304.

[0040] The cleaning block 304 has a parking opening 206 on one side. After the cleaning work is completed, the cleaning block 304 can be moved to the parking opening 206. Since the height of the parking opening 206 is three times the thickness of the cleaning block 304, the cleaning block 304 can be easily placed in the parking opening 206 without affecting the normal operation of the upper leveling roller 103.

[0041] Furthermore, a rotating shaft 306 is fixedly connected to the end of the lead screw 302 away from the motor 301, and the outer ring of the rotating shaft 306 is fixedly connected to the connecting block 202.

[0042] When the motor 301 drives the lead screw 302 to rotate, the rotating shaft 306 provides support, keeping the lead screw 302 stable during rotation.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
