through setting up first 20 and second 21 of projection, because length difference between them, make the position of ring groove inconsistent, when making two connecting rod 19 cross motions, can not mutual interference, simultaneously, because cylinder 8 is responsible for compressing tightly panel, the turned angle of commentaries on classics board 18 is less, whole week motion can not appear in connecting rod 19, furthermore, because first 16 and second 17 spacer rings, friction when the semicircle ball is first can reduce the commentaries on classics board 18 and move with semicircle ball two, and the axial that can avoid changeing board 18 when moving rocks.

Aiming at the axis position of the rolling mill for adjusting the plate; as shown in fig. 1, 6, 7 and 8, the leveling assembly 3 includes a main frame 22 and a sliding frame 23, four sets of sliding assemblies 26 are fixedly connected to an outer wall of one side of the main frame 22, a counterweight assembly 24 is fixedly connected to an outer wall of the top of the main frame 22, each sliding assembly 26 includes a standing frame 27 and two baffles 28, an outer wall of one side of the standing frame 27 is fixedly connected to an outer wall of one side of the main frame 22, the number of the baffles 28 is two, and an outer wall of one side of each baffle 28 is respectively and fixedly connected to outer walls of the top and the bottom; the inner wall of the upright frame 27 is provided with a sliding block 30, the inner wall of one side of the sliding block 30 is rotatably connected with a main wheel 32 through a shaft, the inner walls of two sides of the sliding block 30 are rotatably connected with auxiliary wheels 31 through shafts, the outer wall of the main wheel 32 is connected with the inner wall of one side of the upright frame 27 in a rolling manner, and the auxiliary wheels 31 are connected with the inner walls of two sides of the upright frame 27 in a rolling; the outer wall of one side of the baffle 28 is fixedly connected with a buffer rod 29, the outer wall of one end of the buffer rod 29 is attached to the outer wall of one side of the sliding block 30, the outer wall of one side of the sliding frame 23 is fixedly connected to the outer wall of one side of the sliding block 30, the number of the sliding frames 23 is two, and the outer walls of the top and the bottom of the transverse frame 5 are fixedly connected between the two sliding frames 23; the counterweight assembly 24 comprises a top plate 33 and eight hangers 39, the outer wall of the bottom of the top plate 33 is fixedly connected to the outer wall of the top of the main frame 22, the outer walls of the bottoms of the four hangers 39 are fixedly connected to the outer wall of the top plate 33, the outer wall of the top plate 33 is fixedly connected with two second supports 38, and the outer walls of two sides of the top plate 33 are fixedly connected with two first supports 37; the outer walls of the tops of the other four hanging frames 39 are fixedly connected to the outer walls of the bottoms of the first support 37 and the second support 38, the inner walls of the hanging frames 39 are rotatably connected with fixed wheels 40 through shafts, the outer wall of the top of one sliding frame 23 is fixedly connected with a locking block 25, the outer wall of the top of the locking block 25 is rotatably connected with belt wheels through shafts, the belt wheels and the outer wall of the fixed wheel 40 are matched with belts 36, the belts 36 are E-shaped structures, the inner walls of two ends of each belt 36 are rotatably connected with hanging wheels 35, the central inner wall of each hanging wheel 35 is rotatably connected with a hanging frame, and the outer wall of; by arranging the leveling component 3, the clamping component 2 is fixedly connected between the two sliding frames 23, after a plate enters the rolling mill body 4, the whole plate needs to be adjusted along with the height of the material in the rolling mill due to the bending influence possibly caused by centering operation and plate leveling, the sliding block 30 drives the sliding frames 23 to move for leveling and centering work, meanwhile, the buffer rod 29 can avoid the plate from shaking up and down in the rolling process, and meanwhile, the main wheel 32 and the auxiliary wheel 31 can avoid the sliding block 30 from being blocked on the inner wall of the vertical frame 27 due to the sliding of the sliding block 30; through setting up the counter weight assembly 24, wherein because the structure of belt 36, can make the removal of balancing weight 34 more level and smooth, rely on fixed pulley 40 and gallows 39 simultaneously, can adjust the relative height of two balancing weights 34 for counter weight assembly 24 itself is in steady state, and because the existence of counter weight assembly 24, can make chucking subassembly 2 and two sliding frame 23 be in balanced state, makes leveling subassembly 3 can not the bending panel when the leveling, ensures rolling effect.

In use, the sheet material is passed through the clamping assembly 2, the front end of the sheet material pushes the roller 8 open, the roller 8 moves, the fixed shaft 9 drives the arm support 7 to rotate around the rotating plate 18, the rotating plate 18 rotates, the convex column I20 and the convex column II 21 drive the other rotating plate 18 to rotate, namely, when the plate is pushed forward and ejected, the connecting rods 19 are assembled in a crossed manner, the two rotating plates 18 on one side of the transverse frame 5 can be driven to rotate at the same time, after the plate passes through the roller 8, the arm support 7 is driven to reset under the action of the elastic telescopic rod 10, the plate is clamped, so that the plate can be prevented from shaking and prying during subsequent rolling, and after the plate enters the rolling mill body 4, due to the bending influence possibly caused by centering operation and plate flattening, the whole plate needs to be adjusted along with the height of the material in the rolling mill, the sliding block 30 drives the sliding frame 23 to move to perform leveling centering work, and meanwhile the buffer rod 29 can avoid the up-and-down shaking of the plate in the rolling process.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
