[0002] The descriptions in this section provide background information relating to this disclosure and do not constitute prior art.

[0003] Roller-type steel plate leveling machines are mainly used for straightening plates of various specifications. The straightening requirements for the center and edges of wide steel plates may differ. Since the center of a wide steel plate usually bears greater stress, a higher straightening pressure is required to ensure the straightening effect. Higher pressure helps eliminate larger deformations and internal stresses in the center; the stress in the edge area is relatively smaller, so the straightening pressure can be appropriately reduced. Excessive pressure may cause over-straightening of the edges, or even create new deformations. Multi-roller overall adjustment cannot meet the differentiated straightening needs. Summary of the Invention

[0004] The purpose of this utility model is to provide a multi-roller leveling machine for wide steel plates, which reduces the distance between the pressure rollers in the center and increases the distance between the pressure rollers at the edges; and solves the technical problem that the leveling requirements of the center and the edges may be different, and the overall adjustment of the multi-rollers cannot meet the differentiated leveling needs of wide steel plates.

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

[0023] Please see Figure 1-5 This utility model provides a technical solution: a wide-width steel plate multi-roller leveling machine, comprising: Side plate 1, which has two parallel distributions at the front and back; A rectangular groove 2 is provided in the middle of the bottom surface of the side plate 1; The front and rear side walls of side panel 1 are both provided with horizontally extending strip-shaped sliding installation windows 4; There are six lower pressure rollers 5 that are slidably inserted into the front and rear strip sliding installation windows 4; The bearing housing 12, which is fixedly sleeved on both sides of the lower pressure roller 5 through the outer wall, slides within the strip-shaped sliding installation window 4; The density of the six lower pressure rollers 5 gradually increases from the outside to the inside; A rotary transmission structure 6 is assembled between the front end of the six lower pressure rollers 5 and the front wall of the front side plate 1. A strip mounting plate 3 is provided at the upper end of the side plate 1, and a lifting limit bracket 8 is installed between its end and the end of the same side of the side plate 1. The inner side of the strip mounting plate 3 is provided with a horizontal strip groove 11; Five upper pressure rollers 10 are slidably assembled in the front and rear strip grooves 11; The upper pressure roller 10 slides within the strip groove 11 through the bearing seats 12 fixedly sleeved on the outer wall at both ends. Five upper pressure rollers 10 are distributed above the adjacent gaps of six lower pressure rollers 5; Lifting and positioning structures 7 are installed between the inner wall of the strip groove 11 and the top surface of the strip mounting plate 3 on the same side, and between the inner wall of the strip sliding installation window 4 and the top surface of the rectangular groove 2 on the same side.

[0024] Specifically, in this embodiment, the two ends of the lower pressure roller 5 slide within the front and rear strip sliding installation windows 4 through the bearing seats 12 fixedly sleeved at the ends. The lifting and positioning structure 7 clamps and limits the bearing seats 12 after the sliding adjustment position. After being limited, the lower pressure roller 5 can rotate within the front and rear bearing seats 12. The two ends of the upper pressure roller 10 slide within the front and rear strip slide grooves 11 through the bearing seats 12 fixedly sleeved at the ends. The lifting and positioning structure 7 clamps and limits the bearing seats 12 after the sliding adjustment position. After being limited, the upper pressure roller 10 can rotate within the front and rear bearing seats 12. Furthermore, a strip-shaped sliding installation window 4 is opened laterally on the front and rear side plates 1 for sliding six lower pressure rollers 5. The distribution density of the six lower pressure rollers 5 gradually increases from the outside to the inside, reducing the pressure roller spacing in the center part and increasing the accuracy and effect of leveling; increasing the pressure roller spacing in the edge part reduces the over-leveling of the edge, while improving the leveling efficiency and meeting the leveling needs of the center and edge of the wide steel plate. More specifically, for the multi-roller leveling machine designed for wide steel plates, the lateral positions of the bearing seats 12 at both ends of the lower pressure roller 5 and the upper pressure roller 10 can be slidably adjusted in the corresponding slide grooves, thereby adjusting the distribution spacing of the lower pressure roller 5 and the upper pressure roller 10 according to the size of the steel plate, and is suitable for leveling steel plates of different widths within a certain range. It is understandable that the lifting limit bracket 8 adjusts the height of the strip mounting plate 3, thereby driving the upper pressure roller 10 to rise and fall accordingly, adjusting the distance between the upper pressure roller 10 and the lower pressure roller 5, which is suitable for leveling steel plates of different thicknesses and widths within a certain range.

[0025] In some embodiments, the rotary transmission structure 6 includes: The first gear 61 is coaxially fixedly mounted on the front end of the lower pressure roller 5; The left end of the strip-shaped sliding installation window 4 extends to the left, and a chain tensioning structure 65 is installed between its interior and the front wall of the front side panel 1. The outer wall of the first gear 61 is meshed with the outer wall of the movable end of the chain tensioning structure 65, and the chain 64 is sleeved thereon. A drive motor 62 is fixedly mounted on the middle of the front wall of the rightmost first gear 61, and an L-shaped connecting seat 63 is fixedly mounted on the lower end of its outer wall. A strip-shaped mounting through hole 66 is provided on the transverse part of the front wall of the front side plate 1 corresponding to the L-shaped connecting seat 63; Bolts and nuts are fixedly connected between the rear end of the horizontal part of the L-shaped connector 63 and the strip-shaped mounting through hole 66.

[0026] Specifically in this embodiment, the drive motor 62 is connected to an external power source and drives the rightmost first gear 61 to rotate. This first gear 61 drives the chain 64 to drive the other first gears 61 to rotate, which in turn drives the lower pressure roller 5 to rotate, which is used to flatten the wide steel plate that is conveyed in by external force. Furthermore, the bolt of the bolt connected to the lateral part of the L-shaped connecting seat 63 is inserted into the strip-shaped mounting through hole 66. After loosening the nut, the bolt can be adjusted laterally within the strip-shaped mounting through hole 66, so that the drive motor 62 can adjust its lateral position along with the rightmost first gear 61. After adjustment, the nut is tightened again to limit and fix the current position, and the lateral position of the rightmost lower pressure roller 5 can be adjusted within a certain range.

[0027] In some embodiments, the chain tensioning structure 65 includes: Mounting plate 652 is fixedly assembled to the left edge of the front wall of front side plate 1; The right end of the mounting plate 652 is vertically fixedly equipped with a first electric push rod 653, and its telescopic end is fixedly equipped with a sleeve 651. A shaft 654 is inserted into the sleeve 651, and its rear end is slidably inserted into the strip-shaped sliding installation window 4 on the same side. The second gear 655 is fixedly sleeved at the rear end of the outer wall of the sleeve 651, and its outer wall meshes with the inner wall of the chain 64.

[0028] Specifically in this embodiment, the first electric push rod 653 is connected to an external power source. The first electric push rod 653 drives the sleeve 651 and the internal shaft 654 to extend and retract laterally to adjust their positions, thereby driving the second gear 655 to move laterally. When the rightmost first gear 61 moves to the left, the leftward movement of the second gear 655 compensates for the tension of the chain 64. Furthermore, before adjusting the lateral position of the lower pressure roller 5, the first electric push rod 653 is driven to move the second gear 655 to the right, so that the chain 64 is relaxed and the chain 64 will not obstruct the lateral displacement of the first gear 61.

[0029] In some embodiments, the lifting and positioning structure 7 includes: Pressure plate 71 is slidably assembled on the lower end of the inner wall of the strip sliding installation window 4 or the upper end of the inner wall of the strip slide groove 11; The top surface of the strip mounting plate 3 or the top surface of the rectangular groove 2 are vertically and fixedly equipped with the second electric push rod 72 on both the left and right sides, and its telescopic end is fixedly connected to the outer side of the corresponding pressure plate 71 on the same side. The pressure plate 71 abuts against the outer wall of the corresponding bearing housing 12; Both the inner and outer surfaces of the bearing housing 12 are designed as planes; The inner end plane of the upper bearing seat 12 is in contact with the inner wall of the strip groove 11; The inner end plane of the lower bearing seat 12 is in contact with the inner wall of the strip-shaped sliding installation window 4; The inner side of the pressure plate 71 is in contact with the outer end plane of the bearing seat 12 on the same side; The opposite surfaces of the upper and lower pressure plates 71 are both provided with anti-slip texture.

[0030] Specifically in this embodiment, the second electric push rod 72 is connected to an external power source. The two second electric push rods 72 are controlled by an external controller to drive the pressure plate 71 to rise and fall synchronously. When the pressure plate 71 abuts against the outer wall of the bearing seat 12, it is limited. When the pressure plate 71 moves outward away from the bearing seat 12, the bearing seat 12 can slide laterally within the corresponding sliding range. Adjust the lateral position of the lower pressure roller 5 or the upper pressure roller 10. After adjustment, the pressure plate 71 moves inward again to abut against the outer wall of the bearing seat 12 for limitation. Furthermore, the upper and lower surfaces of the bearing housing 12 are provided with planes, which are better pressed and limited by the pressure plate 71 in the corresponding slide groove, without affecting the lateral adjustment position of the bearing housing 12. More specifically, the anti-slip texture on the opposite side of the pressure plate 71 increases friction, and provides more stable limiting and clamping when it contacts the bearing seat 12.

[0031] In some embodiments, the lifting limit bracket 8 includes: The first connecting plate 81 is horizontally fixedly assembled to the upper edge of the end of the strip mounting plate 3; The second connecting plate 82 is horizontally fixedly assembled to the upper edge of the end of the side plate 1; A third electric push rod 83 is vertically fixedly mounted on the bottom surface of the first connecting plate 81, and its telescopic upper end is fixedly connected to the bottom surface of the corresponding first connecting plate 81 above. A limit structure is assembled on the outer end of the position corresponding to the position between the first connecting plate 81 and the second connecting plate 82. The limiting structure includes: The screw 84 passes through the first connecting plate 81 and the second connecting plate 82 from top to bottom; The upper and lower ends of the outer wall of the screw 84 are screwed with nut groups 85, which consist of two fixing nuts; The two fixing nuts of the upper and lower nut assembly 85 abut against the upper and lower surfaces of the first connecting plate 81 and the second connecting plate 82, respectively.

[0032] Specifically in this embodiment, the third electric push rod 83 is connected to an external power source, and the third electric push rod 83 on the same side at the front and rear are controlled to work synchronously by an external controller; Furthermore, the third electric push rod 83 drives the first connecting plate 81 and the strip mounting plate 3 to rise and fall, and the limiting structure is used to limit and fix the current height of the adjusted strip mounting plate 3; More specifically, the limiting structure uses a screw 84 to pass through the first connecting plate 81 and the second connecting plate 82. Fixing nuts are screwed onto the outer wall of the screw 84 near the upper and lower sides of the first connecting plate 81 and the second connecting plate 82. The fixing nuts are used to abut against the upper and lower surfaces of the first connecting plate 81 and the second connecting plate 82 for positioning. It is understandable that loosening the screws and moving the fixing nuts outwards allows space for the lifting and adjustment of the first connecting plate 81 and the strip mounting plate 3, enabling the height of the first connecting plate 81 and the strip mounting plate 3 to be adjusted within a certain range.

[0033] In some embodiments, a steel plate discharge bracket 9 is horizontally fixedly mounted on the right end of the front and rear side plates 1. The upper surface of the steel plate discharge bracket 9 and the upper surface of the lower pressure roller 5 are located on the same plane; The steel plate discharge bracket 9 has a ramp 94 at its left end, which slopes downwards. The steel plate discharge bracket 9 includes: The mounting base plate 91 is inserted into the right end of the front and rear side plates 1; The upper end of the mounting base plate 91 is provided with a supporting top plate 93, and springs 92 are evenly fixedly mounted between its bottom surface and the upper end of the mounting base plate 91. The outer wall of the right end of the front and rear side plates 1 is screwed with fixing bolts 95, the ends of which are screwed to the outer wall of the mounting base plate 91 on the same side.

[0034] Specifically in this embodiment, the leveled wide steel plate conveyed between the lower pressure roller 5 and the upper pressure roller 10 is moved to the support top plate 93, and the support top plate 93 provides discharge support for it. Furthermore, the ramp 94 serves as a material guide. When the right end of the leveled wide steel plate is too low, the ramp 94 can guide the material to fall onto the supporting top plate 93, ensuring smooth material discharge. More specifically, spring 92 acts as a shock absorber, buffering the force on the supporting top plate 93.

[0035] 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.
