[0023] like Figure 1 and Figure 2As shown, this embodiment provides a rotating structure bouncing roller tension adjustment device, including a frame 1, a first steering roller 2, a second steering roller 3, a bouncing roller 5, a bouncing roller bracket 6 and a driving member 8, wherein the first steering roller 2 and the second steering roller 3 are parallelly mounted on the frame 1 at the same height, the bouncing roller bracket 6 is located below the first steering roller 2 and the second steering roller 3, the bouncing roller bracket 6 is rotatably connected to the frame 1 through a rotating shaft 7, the bouncing roller 5 is connected to the end of the bouncing roller bracket 6 close to the first steering roller 2, the rotating shaft 7 is connected to the end of the bouncing roller bracket 6 away from the first steering roller 2, and the bouncing roller 5 and the rotating shaft 7 are arranged parallel to the first steering roller 2 and the second steering roller 3, one end of the driving member 8 is connected to the rotating shaft 7, and the other end is fixedly mounted on the frame 1. During operation, the strip 4 passes around the top of the first steering roller 2, the bottom of the bouncing roller 5 and the top of the second steering roller 3 in turn. The driving member 8 provides a stable output force, and the constant force output by the driving member 8 is transmitted to the bouncing roller 5 through the bouncing roller bracket 6, so that the bouncing roller 5 rotates around the rotating shaft 7 of the bouncing roller bracket 6. At the same time, since the strip 4 wraps around the bouncing roller 5, the bouncing roller 5 can move up and down under the action of the tension of the strip 4 and the output force transmitted by the driving member 8. Through the movement of the bouncing roller 5, the tension fluctuation of the strip 4 is compensated and adjusted, thereby achieving the stabilization and control of the tension of the strip 4, thereby effectively avoiding the phenomenon of strip breakage and strip wrinkles in the furnace, and reducing the scrap rate.

[0024] Among them, the driving member 8 can adopt but is not limited to a low-speed cylinder. The selection of the low-speed cylinder ensures that the power output by it can be transmitted to the bouncing roller 5 at the other end of the bouncing roller bracket 6 with high precision, which is beneficial to the precise control of the tension of the plate strip 4.

[0025] Preferably, the bouncing roller 5 is located directly below the middle position of the first steering roller 2 and the second steering roller 3; further, the spacing between the first steering roller 2 and the second steering roller 3 can be designed to be equal to the diameter of the bouncing roller 5, so that the plate strip 4 is in a vertical state between the bouncing roller 5 and the first steering roller 2 and the second steering roller 3, which is conducive to the precise control of the tension of the plate strip 4.

[0026] Optional implementations, such as Figure 1 As shown, the bouncing roller bracket 6 can adopt an H-shaped structure, and the horizontal section of the H-shaped structure is arranged with the first steering roller 2 and the second steering roller 3, and the bouncing roller 5 and the rotating shaft 7 are respectively located on the upper and lower sides of the horizontal section of the H-shaped structure, and the two ends of the bouncing roller 5 are respectively rotatably connected to the two vertical sections of the H-shaped structure through bearings to ensure that the bouncing roller 5 can rotate freely, thereby reducing the friction resistance between the plate belt 4 and the bouncing roller 5 during operation, and the two ends of the rotating shaft 7 are respectively connected to the frame 1 through the two vertical sections of the H-shaped structure.

[0027] In an optional embodiment, the driving member 8 is connected to the rotating shaft 7 through a force transmission member 9, the force transmission member 9 is suspended on the rotating shaft 7, the driving member 8 is hinged to the lower end of the force transmission member 9, and the power output direction of the driving member 8 is horizontal. In the initial state, the output force of the driving member 8 is calculated according to the mass of the bouncing roller 5 and the bouncing roller bracket 6, so that the bouncing roller 5 maintains balance under the action of the tension of the plate strip 4 and the output force of the driving member 8, and when the tension of the plate strip 4 fluctuates, the output force of the driving member 8 (low-speed cylinder) is adjusted to drive the bouncing roller 5 to rotate around the rotating shaft 7, and the bouncing roller 5 moves up and down, so that the tension of the plate strip 4 maintains a constant tension set theoretically, thereby realizing the control of the tension of the plate strip 4.

[0028] Preferably, the force transmission member 9 is suspended at the center of the rotating shaft 7 to ensure that the bouncing roller bracket 6 is evenly stressed, thereby ensuring the stability of the rotation of the bouncing roller bracket 6 .

[0029] An optimized implementation method, the rotating structure bouncing roller tension adjustment device of this embodiment also includes a tension meter (not shown in the figure) for detecting the tension of the plate strip 4. The tension meter is interlocked with the driving member 8 for control. When working, the bouncing roller 5 moves under the action of the tension of the plate strip 4 and the low-speed cylinder. The tension meter on the production line obtains the actual measured data of the tension of the plate strip 4, and adjusts the air pressure value of the low-speed cylinder according to the measured data, so that the low-speed cylinder generates appropriate force in real time, further ensuring the precise control of the stable tension of the plate strip 4.

[0030] In this embodiment, the rotational connections among the first steering roller 2, the second steering roller 3, the bouncing roller 5, the bouncing roller bracket 6, the driving member 8, and the frame 1 are all connected by low-friction bearings to reduce the influence of system friction on the accuracy of strip tension control.

[0031] The above examples are merely illustrative of the present invention and do not constitute a limitation on the protection scope of the present invention. All designs that are identical or similar to the present invention fall within the protection scope of the present invention.
