Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-3As shown in the figure, a tension leveling device for cold-rolled stainless steel plates includes a support frame 1. A fixed frame 2 is installed on the top side of the support frame 1. A cylinder 3 is assembled on the top side of the fixed frame 2. The acting end of the cylinder 3 slides and extends into the interior of the fixed frame 2 and is fixedly connected to an installation frame 4. A rotating shaft 5 is fixedly installed at equal intervals inside the installation frame 4. An upper tension leveling roller 6 is rotatably installed on the outer wall of the rotating shaft 5. An L-shaped rod 7 is installed on one side of one of the rotating shafts 5. A through groove is formed on one side of the fixed frame 2. One end of the L-shaped rod 7 passes through the through groove and is installed with an indicating needle 8. A scale line 9 is engraved on one side of the fixed frame 2. Two support rods 10 are symmetrically installed on the top side of the installation frame 4. One end of the support rod 10 slides and extends to the top side of the fixed frame 2. An electrode 11 is installed on the outer wall of the top end of the support rod 10. A scale rod 12 is installed at the edge of the top side of the fixed frame 2. A limit ring 13 is slidably installed on the outer wall of the scale rod 12. A locking screw 14 is rotatably installed inside the limit ring 13. An electric sheet 15 is installed on the outer wall of the limit ring 13. A lower tension leveling roller 22 is installed between the two conveying rollers 17 on both sides of the support frame 1 through pin shafts. A control panel 35 is installed on one side of the support frame 1. During operation, in the prior art, it is not convenient to adjust the distance between the upper tension leveling roller 6 and the lower tension leveling roller 22, resulting in inconvenience in adapting to cold-rolled stainless steel plates of different specifications and materials, and the tension leveling effect is not good. According to the fact that the distance between the electrode 11 and the electric sheet 15 is equal to the distance between the bottom arc surface of the upper tension leveling roller 6 and the cold-rolled plate, that is, by checking the distance between the indicating needle 8 and the cold-rolled plate, then the limit ring 13 slides on the scale rod 12 to adjust the distance between the electric sheet 15 and the electrode 11. Finally, the limit ring 13 is fixed by the locking screw 14. Subsequently, the cylinder 3 is operated through the control panel 35. The acting end of the cylinder 3 pushes the installation frame 4 to move downward, and the upper tension leveling roller 6 approaches the lower tension leveling roller 22 accordingly. The support rod 10 also moves with the installation frame 4, and the electrode 11 also changes its position accordingly. When the electrode 11 contacts the electric sheet 15, an electric signal will be generated and transmitted to the control panel 35. After receiving the signal, the control panel 35 controls the cylinder 3 to close, achieving precise adjustment of the position of the upper tension leveling roller 6, thereby controlling the distance from the lower tension leveling roller 22 and ensuring the tension leveling effect.

[0024] Please refer to Figure 4As shown, rotating shafts 16 are installed through both sides between the two ends of the support frame 1. Conveyor rollers 17 are installed on the outer walls of the rotating shafts 16. One ends of the rotating shafts 16 are respectively installed with a driving wheel 18 and a driven wheel 19, and the driving wheel 18 and the driven wheel 19 are drivingly connected through a belt 20. A conveyor motor 21 is installed on one side of the support frame 1, and one end of the rotating shaft 16 is connected to the output end of the conveyor motor 21. One end of the top side of the support frame 1 is fixed with a mounting frame 28. A chute 29 is opened inside the top side of the mounting frame 28. Sliders 30 are slidably installed at both ends of the chute 29. A servo motor 31 is installed on one side of the mounting frame 28. A bidirectional lead screw 32 is installed at the output end of the servo motor 31. A threaded hole is opened inside the bottom end of the slider 30. One end of the bidirectional lead screw 32 penetrates through the threaded hole and is rotatably installed on one side of the mounting frame 28. A fixed frame 33 is connected to the bottom side of the slider 30. Three auxiliary rollers 34 are equidistantly installed inside the fixed frame 33 through pin shafts; during operation, after the stainless steel cold-rolled plate is annealed, it often has a poor plate shape, so a tension leveling device is needed for correction. To ensure the continuity of the tension leveling operation, start the conveyor motor 21, whose output end drives the rotating shaft 16 to rotate. The driving wheel 18 drives the driven wheel 19 to rotate through the belt 20, and then the rotating shaft 16 drives the conveyor roller 17 to rotate, realizing the conveying of the stainless steel cold-rolled plate. According to the size of the cold-rolled plate, start the servo motor 31. The servo motor 31 drives the bidirectional lead screw 32 to rotate, so that the two sliders 30 move in opposite or the same directions along the chute 29 at the same time. The movement of the sliders 30 drives the fixed frame 33 and the auxiliary rollers 34 to move. By adjusting the positions of the two sliders 30, the positions and distances of the auxiliary rollers 34 can be changed, and then the cold-rolled plate with different widths can be limited and conveyed. During the tension leveling operation, the upper tension leveling roller 6 and the lower tension leveling roller 22 act together to apply a certain tensile force and straightening force to the cold-rolled plate, making it change from a bent state to a straight state.

[0025] Please refer to Figure 5 As shown, a support 23 is installed on one side of the support frame 1. A driving motor 24 is installed inside the support 23. A connecting rod 25 is installed at the output end of the driving motor 24. A connecting shaft 26 is fixedly connected to one side of the connecting rod 25. A reel 27 is movably installed on the outer wall of the connecting shaft 26; during operation, the adjustment of the unwinding angle can affect the tension distribution of the sheet material during the tension leveling process, avoiding problems such as wrinkling, excessive stretching or breaking of the sheet material. Start the driving motor 24, whose output end drives the connecting rod 25 to rotate, and then drives the rotation of the connecting shaft 26 and the reel 27, so as to facilitate the adjustment of the angle of the reel 27, and the precise control of the tension of the cold-rolled plate can be realized, improving the tension leveling quality and production efficiency.

[0026] Working principle: The limit ring 13 slides on the scale rod 12 to adjust the distance between the electric plate 15 and the electrode 11. Finally, the limit ring 13 is fixed by the locking screw 14. Then, the cylinder 3 is operated through the control panel 35. The acting end of the cylinder 3 pushes the mounting frame 4 downward, and the upper tension roller 6 approaches the lower tension roller 22 accordingly. The support rod 10 also moves with the mounting frame 4, and the electrode 11 also changes its position accordingly. When the electrode 11 contacts the electric plate 15, an electrical signal is generated and transmitted to the control panel 35. After receiving the signal, the control panel 35 controls the cylinder 3 to close, which can accurately adjust the position of the upper tension roller 6, thereby controlling the distance between it and the lower tension roller 22 to ensure the tension leveling effect.

[0027] Start the conveyor motor 21, whose output end drives the rotating shaft 16 to rotate. The driving wheel 18 drives the driven wheel 19 to rotate through the belt 20, and then the rotating shaft 16 drives the conveyor roller 17 to rotate to realize the conveying of the cold-rolled stainless steel plate. According to the size of the cold-rolled plate, start the servo motor 31. The servo motor 31 drives the bidirectional lead screw 32 to rotate, so that the two sliders 30 move along the chute 29 in opposite or the same direction at the same time. The movement of the sliders 30 drives the fixed frame 33 and the auxiliary roller 34 to move. By adjusting the positions of the two sliders 30, the position and spacing of the auxiliary roller 34 can be changed, and then the cold-rolled plates of different widths can be limited for conveying. During the tension leveling operation, the upper tension roller 6 and the lower tension roller 22 act together to apply a certain tensile force and straightening force to the cold-rolled plate to change it from a bent state to a straight state.

[0028] Start the drive motor 24, whose output end drives the connecting rod 25 to rotate, and then drives the rotation of the connecting shaft 26 and the reel 27, so as to facilitate the adjustment of the angle of the reel 27, and can realize the precise control of the tension of the cold-rolled plate, improving the tension leveling quality and production efficiency.
