[0024] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the detailed implementation mode.

[0025] As Figures 1-4 shown, a steel plate leveling machine includes a bottom plate 1. The right part of the top of the bottom plate 1 is fixedly connected with a mounting frame 11. The front and rear positions of the right part of the top of the bottom plate 1 are both fixedly connected with support plates 13. The left part of the top of the bottom plate 1 is fixedly connected with a fixed seat 12. The top of the fixed seat 12 is slidably connected with a steel plate 5. The top of the rear support plate 13 is fixedly connected with a cleaning mechanism 2. The top of the mounting frame 11 is fixedly connected with a leveling mechanism 3. The front and rear ends of the fixed seat 12 are both fixedly connected with a guiding mechanism 4. The cleaning mechanism 2 includes a first motor 21. The front end of the first motor 21 is fixedly connected with the top of the rear support plate 13. The leveling mechanism 3 includes a telescopic cylinder 31. The bottom end of the telescopic cylinder 31 is fixedly connected with the top of the mounting frame 11. The guiding mechanism 4 includes two mounting plates 41. The bottom of the mounting plate 41 is fixedly connected with the top of the fixed seat 12.

[0026] The outer wall of the steel plate 5 is cleaned by the cleaning mechanism 2 to avoid attachment of debris such as iron filings on the outer wall of the steel plate 5. Subsequently, the steel plate 5 is leveled by the leveling mechanism 3, and the leveled steel plate 5 is conveyed. During the conveying process, the steel plate 5 is guided by the guiding mechanism 4.

[0027] As Figure 2 、 Figure 4 shown, the bottom of the mounting frame 11 is rotatably connected with a support frame 14. The outer wall of the support frame 14 is rotatably connected with a first leveling roller 15. The front end of the support frame 14 is fixedly connected with a connecting plate 16. The outer wall of the connecting plate 16 is slidably connected with the bottom of the mounting frame 11. The top of the connecting plate 16 is inserted with a first insertion rod 17. The outer wall of the first insertion rod 17 is inserted into the bottom of the mounting frame 11. The front part of the first insertion rod 17 is fixedly connected with a first spring 18. The rear end of the first spring 18 is fixedly connected with the front end of the connecting plate 16.

[0028] By pulling the first inserting rod 17, the first spring 18 is stretched, so that the outer wall of the first inserting rod 17 is no longer inserted into the inner wall of the mounting frame 11. Then, the connecting plate 16 is rotated, and the connecting plate 16 drives the supporting frame 14 and the first leveling roller 15 to rotate synchronously, so that the first leveling roller 15 suitable for the current width rotates to the upper side. After the adjustment is completed, the first inserting rod 17 is released, and under the action of the elastic force of the first spring 18, the outer wall of the first inserting rod 17 is inserted into the inner wall of the mounting frame 11, thereby completing the limit and preventing the first leveling roller 15 from rotating.

[0029] As Figure 2 、 Figure 3 As shown, the outer wall of the output end of the first motor 21 is rotatably connected to the top of the support plate 13. The front part of the output end of the first motor 21 is fixedly connected with a driving wheel 23. The outer wall of the driving wheel 23 is drivingly connected with a transmission belt 24. The bottom of the transmission belt 24 is drivingly connected with a driven wheel 25. The axis of the driven wheel 25 is fixedly connected with a rotating shaft 26. The outer walls of the rotating shaft 26 and the output end of the first motor 21 are both fixedly connected with cleaning rollers 22.

[0030] By starting the first motor 21, the first motor 21 drives the driving wheel 23 to rotate. The driving wheel 23 drives the transmission belt 24 to rotate synchronously. The transmission belt 24 drives the driven wheel 25 to rotate synchronously. The driven wheel 25 drives the rotating shaft 26 to rotate. Thus, the first motor 21 and the rotating shaft 26 drive the cleaning rollers 22 to rotate synchronously. The cleaning rollers 22 clean the outer wall of the steel plate 5, avoiding the attachment of debris such as iron filings on the outer wall of the steel plate 5, and achieving the cleaning effect.

[0031] As Figure 2 、 Figure 4 As shown, the output end of the telescopic cylinder 31 is fixedly connected with a connecting frame 32. The front and rear parts of the top end of the connecting frame 32 are both fixedly connected with the first guide rods 33. The outer walls of the first guide rods 33 are slidably connected to the top of the mounting frame 11. The front and rear ends of the connecting frame 32 are both fixedly connected with limiting blocks 321. The outer walls of the limiting blocks 321 are slidably connected to the top of the mounting frame 11. The shape of the limiting blocks 321 is T-shaped. The front and rear positions at the bottom of the connecting frame 32 are both rotatably connected with fixing blocks 34. The upper and lower parts of the inner cavity of the front fixing block 34 are both fixedly connected with the second motors 35. The outer walls of the output ends of the second motors 35 are fixedly connected with the second leveling rollers 351.

[0032] Start the telescopic cylinder 31 to drive the connecting frame 32 to move downward, causing the connecting frame 32 to drive the first guide rod 33 to slide synchronously on the inner wall of the mounting frame 11. At the same time, the connecting frame 32 drives the limit block 321 to slide on the inner wall of the mounting frame 11. The limit block 321 and the first guide rod 33 limit and guide the connecting frame 32, making the movement of the connecting frame 32 more stable. At the same time, the connecting frame 32 drives the second leveling roller 351 to move synchronously, so that the outer wall of the second leveling roller 351 contacts the outer wall of the steel plate 5. Then, the telescopic cylinder 31 can be closed, and then the second motor 35 is started. The second motor 35 drives the second leveling roller 351 to rotate, so that the second leveling roller 351 and the first leveling roller 15 level the steel plate 5, which facilitates the leveling of steel plates 5 with different thicknesses and achieves the effect of being able to level steel plates 5 with different thicknesses.

[0033] As Figure 2 、 Figure 4 shown, a second plug rod 36 is inserted into the rear part of the connecting frame 32. A second spring 361 is fixedly connected to the right part of the second plug rod 36. The left end of the second spring 361 is fixedly connected to the bottom of the connecting frame 32. The outer wall of the second plug rod 36 is inserted into the inner wall of the rear fixed block 34.

[0034] By pulling the second plug rod 36, the second spring 361 is stretched, and the outer wall of the second plug rod 36 is no longer inserted into the inner wall of the fixed block 34. Then the fixed block 34 can be rotated to drive the second leveling roller 351 to rotate synchronously, so that the steel plate 5 suitable for the current width rotates to the lower side. Then release the second plug rod 36. Under the action of the elastic force of the second spring 361, the outer wall of the second plug rod 36 is inserted into the inner wall of the fixed block 34 again, thereby preventing the subsequent rotation of the second leveling roller 351.

[0035] As Figure 2 、 Figure 5 shown, an electric telescopic rod 42 is fixedly connected to the top of the mounting plate 41. The output end of the electric telescopic rod 42 is fixedly connected to a fixed frame 43. Both the left and right parts of one end of the fixed frame 43 are fixedly connected to second guide rods 44. The outer walls of the second guide rods 44 are slidably connected to the top of the mounting plate 41. Guide wheels 45 are rotatably connected to the inner wall of the fixed frame 43 in a linear array.

[0036] By starting the electric telescopic rod 42, the fixed frame 43 is driven to move synchronously. The fixed frame 43 drives the second guide rods 44 to slide on the inner wall of the mounting plate 41. The second guide rods 44 guide the fixed frame 43, making the movement of the fixed frame 43 more stable. At the same time, the fixed frame 43 drives the guide wheels 45 to move synchronously, so that the outer walls of the guide wheels 45 contact the outer wall of the steel plate 5, thereby guiding the steel plate 5 and preventing the steel plate 5 from shifting during movement, achieving the guiding effect.

[0037] Working principle of the utility model: During use, according to the width of the steel plate 5, pull the first plug rod 17 to stretch the first spring 18, so that the outer wall of the first plug rod 17 is no longer inserted into the inner wall of the mounting frame 11. Then rotate the connecting plate 16, and the connecting plate 16 drives the support frame 14 and the first leveling roller 15 to rotate synchronously, so that the first leveling roller 15 suitable for the current width rotates to the upper side. After the adjustment is completed, release the first plug rod 17. Under the action of the elastic force of the first spring 18, the outer wall of the first plug rod 17 is inserted into the inner wall of the mounting frame 11, thereby completing the limit and preventing the first leveling roller 15 from rotating. Then pull the second plug rod 36 to stretch the second spring 361, so that the outer wall of the second plug rod 36 is no longer inserted into the inner wall of the fixed block 34, and then the fixed block 34 can be rotated to drive the second leveling roller 351 to rotate synchronously, so that the steel plate 5 suitable for the current width rotates to the lower side. Then release the second plug rod 36. Under the action of the elastic force of the second spring 361, the outer wall of the second plug rod 36 is inserted into the inner wall of the fixed block 34 again, thereby preventing the subsequent rotation of the second leveling roller 351. Then the steel plate 5 can be passed through between the two cleaning rollers 22 and the outer wall of the steel plate 5 is brought into contact with the outer wall of the first leveling roller 15. Then start the telescopic cylinder 31 to drive the connecting frame 32 to move downward, so that the connecting frame 32 drives the first guide rod 33 to slide synchronously on the inner wall of the mounting frame 11. At the same time, the connecting frame 32 drives the limiting block 321 to slide on the inner wall of the mounting frame 11. The limiting block 321 and the first guide rod 33 limit and guide the connecting frame 32, making the movement of the connecting frame 32 more stable. At the same time, the connecting frame 32 drives the second leveling roller 351 to move synchronously, so that the outer wall of the second leveling roller 351 is brought into contact with the outer wall of the steel plate 5. Then the telescopic cylinder 31 can be closed, which is convenient for leveling steel plates 5 of different thicknesses and achieves the effect of being able to level steel plates 5 of different thicknesses. During placement, start the first motor 21, and the first motor 21 drives the driving wheel 23 to rotate. The driving wheel 23 drives the transmission belt 24 to rotate synchronously. The transmission belt 24 drives the driven wheel 25 to rotate synchronously. The driven wheel 25 drives the rotating shaft 26 to rotate. Thus, the first motor 21 and the rotating shaft 26 drive the cleaning rollers 22 to rotate synchronously, and the cleaning rollers 22 clean the outer wall of the steel plate 5 to prevent iron filings and other sundries from adhering to the outer wall of the steel plate 5, achieving the cleaning effect. At the same time, start the second motor 35, and the second motor 35 drives the second leveling roller 351 to rotate, so that the second leveling roller 351 and the first leveling roller 15 level the steel plate 5. Due to the contact between the outer wall of the second leveling roller 351 and the outer wall of the steel plate 5, under the action of friction, the steel plate 5 moves leftward. When the outer wall of the steel plate 5 contacts the top end of the fixed seat 12, start the electric telescopic rod 42 to drive the fixed frame 43 to move synchronously. The fixed frame 43 drives the second guide rod 44 to slide on the inner wall of the mounting plate 41. The second guide rod 44 guides the fixed frame 43 to make the movement of the fixed frame 43 more stable. At the same time, the fixed frame 43 drives the guide wheel 45 to move synchronously, so that the outer wall of the guide wheel 45 is brought into contact with the outer wall of the steel plate 5, thereby guiding the steel plate 5 and preventing the steel plate 5 from deviating during movement, achieving the guiding effect.This greatly improves the user experience.
