[0033] like Figures 1 to 4 As shown, this embodiment proposes a clamping roller device, including a housing 1 and a pair of double rocker arm clamping rollers 2. The pair of double rocker arm clamping rollers 2 are arranged vertically at intervals on the housing 1 and can be used to clamp the rolled workpiece. In addition, the housing 1 is also provided with a gearbox assembly 3, which is drivenly connected to the pair of double rocker arm clamping rollers 2. Furthermore, a drive assembly 4 is provided on one side of the housing 1. The housing 1 has a channel through which the drive assembly 4 can extend and be drivenly connected to the gearbox assembly 3. In this way, by setting up a housing 1 and installing a pair of double-rocker arm pinch rolls 2 inside the housing 1, the rolled workpiece can be clamped by the pair of double-rocker arm pinch rolls 2. By installing a gearbox assembly 3 inside the housing 1, the gearbox assembly 3 is driven to drive the pair of double-rocker arm pinch rolls 2. The drive assembly 4 is located on one side of the housing 1, and a channel is opened on the housing 1 for the drive assembly 4 to extend into and drive to drive the gearbox assembly 3, thereby driving the pair of double-rocker arm pinch rolls 2 to rotate. This structural layout integrates the pinch rolls and the gearbox assembly 3 into a single housing 1, effectively reducing space occupation, avoiding the transmission parts passing through the housing wall, simplifying the complexity of the transmission parts, reducing maintenance difficulty, improving transmission efficiency and stability, and thus improving the production efficiency and product quality of the entire rolling line.

[0034] Further, please refer to Figure 1 and Figure 3As shown, the double rocker arm pinch roll 2 includes a rocker arm pinch roll 21, an adjusting rocker arm 22, and a connecting member 23. The connecting member 23 connects the rocker arm pinch roll 21 to the adjusting rocker arm 22. The diameter of the rocker arm pinch roll 21 is larger than the diameter of the adjusting rocker arm 22. Thus, by setting rocker arm pinch rolls 21 and adjusting rocker arms 22 with different diameters and connecting them with the connecting member 23, flexible adjustment of the clamping force on the rolled piece can be achieved. The large diameter design of the rocker arm pinch roll 21 enhances its clamping capacity, making it suitable for stable clamping of larger rolled pieces; while the small diameter of the adjusting rocker arm 22 makes it more flexible in adjusting the clamping position, improving the applicability of the pinch roll and ensuring the stability and accuracy of the rolled piece during the clamping process.

[0035] Further, please refer to Figure 3 As shown, the connector 23 includes a first housing 231, a second housing 232, and a connecting plate 233. The first housing 231 is rotatably sleeved on the rocker arm clamping roller 21, and the second housing 232 is sleeved on the adjusting rocker arm 22. The connecting plate 233 is integrally formed with both the first housing 231 and the second housing 232. Thus, by integrally forming the first housing 231, the second housing 232, and the connecting plate 233, the operator can adjust the first housing 231. The first housing 231, through the connecting plate 233, drives the second housing 232 to rotate. Under the action of the adjusting rocker arm 22, the opening value of the rocker arm clamping roller 21 can be adjusted through the lever principle. The integral design enhances the stability of each structural component and reduces subsequent machining.

[0036] Further, please refer to Figure 4 As shown, the housing 1 is also provided with an adjustment component 5, which can be used to adjust the height of the rocker arm clamping roller 21. Specifically, the adjustment component 5 includes a cylinder device 51 and a first sector gear 52. The cylinder device 51 is mounted on the first housing 231, and the first sector gear 52 is fixedly mounted on the second housing 232. The first sector gear 52 cooperates with the cylinder device 51 to adjust the height of the rocker arm clamping roller 21.

[0037] In this application, the adjustment component 5 operates as follows:

[0038] When the height of the rocker arm pinch roll 21 needs to be adjusted, the cylinder device 51 is activated. The piston rod of the cylinder device 51 extends or retracts, which in turn pushes the first housing 231 to rotate. The first housing 231 drives the second housing 232 to rotate, which in turn drives the first sector gear 52 to rotate. Since the first sector gear 52 is fixedly mounted on the second housing 232, the rotation of the first sector gear 52 will drive the second housing 232 and its adjusting rocker arm 23 to move, thereby realizing the height adjustment of the rocker arm pinch roll 21. This adjustment method is simple and quick, and through the precise control of the cylinder device 51, the height of the rocker arm pinch roll 21 can be precisely adjusted, meeting the different requirements of different rolled products for the clamping distance, and improving the applicability and flexibility of the pinch roll.

[0039] In this application, for ease of description, the pair of rocker arm pinch rollers 23 are designated as the first rocker arm pinch roller and the second rocker arm pinch roller, and the first rocker arm pinch roller and the second rocker arm pinch roller have identical structures. Please refer to [link to application]. Figure 1 As shown, the adjustment component 5 also includes a second sector gear 53, which is disposed on the second housing 232 of the second rocker arm clamping roller, and the first sector gear 52 meshes with the second sector gear 53.

[0040] In this application, when it is necessary to adjust the opening value of a pair of rocker arm pinch rollers 2, the cylinder device 51 is activated. The piston rod of the cylinder device 51 extends or retracts, and the piston rod pushes the first housing 231 to rotate. The first housing 231 drives the second housing 232 to rotate, and the second housing 232 drives the first sector gear 51 to rotate. Since the first sector gear 52 and the second sector gear 53 are meshed, the first sector gear 52 can drive the second sector gear 53 to rotate. Since the second sector gear 53 is fixed on the second housing 232 of the second rocker arm pinch roller, the first sector gear 52 and the second sector gear 53 can synchronously drive the two adjusting rocker arms 22 to move relative to or towards each other. Thus, the two adjusting rocker arms 22 respectively drive the two rocker arm pinch rollers 2 to move synchronously, thereby realizing the adjustment of the opening value of the rocker arm pinch rollers 2.

[0041] Further, please refer to Figure 4 As shown, the first housing 231 is provided with a lug 24. The piston rod of the cylinder device 51 is connected to the lug 24 via a hinge shaft. This connection method makes the cylinder device 51 more stable and reliable when pushing the first housing 231 to rotate, avoiding the shaking problem caused by the direct connection of the piston rod, and further improving the accuracy and stability of adjustment. In addition, the design of the lug 24 also facilitates the installation and debugging by operators, reduces the difficulty of maintenance, and improves work efficiency.

[0042] In practice, operators can adjust the rotation angle of the first housing 231 by controlling the extension or retraction length of the piston rod of the cylinder device 51, thereby achieving precise adjustment of the height of the rocker arm pinch roller 2. Simultaneously, the cooperation between the first sector gear 52 and the cylinder device 51 makes the adjustment process smoother and more continuous, avoiding impacts and vibrations caused by sudden adjustments, protecting the overall structure of the pinch roller device, and extending its service life.

[0043] Further, please refer to Figure 1 As shown, the housing 1 has a positioning hole corresponding to the position of the rocker arm pinch roller 2. The rocker arm pinch roller 2 is equipped with a rolling bearing, which is connected to the positioning hole. This connection between the positioning hole and the rolling bearing not only achieves precise positioning of the rocker arm pinch roller 2, but also reduces motion resistance through the rolling friction of the bearing, making the rotation of the rocker arm pinch roller 2 smoother and improving the transmission efficiency and stability of the pinch roller device. Simultaneously, the design of the positioning hole and the rolling bearing enhances the overall structural strength of the pinch roller device, improving its load-bearing capacity and service life.

[0044] Further, please refer to Figure 3 and Figure 4 As shown, the gearbox assembly 3 includes a first connecting shaft 31 and a second connecting shaft 32. The first connecting shaft 31 and the second connecting shaft 32 are respectively connected to a pair of rocker arm clamping rollers 2. The first connecting shaft 31 is equipped with a first gear 33, and the second connecting shaft 32 is equipped with a second gear 34. The first gear 33 meshes with the second gear 35. Furthermore, the second connecting shaft 32 is equipped with a third gear 35, which is connected to the drive assembly 4. Thus, through the meshing transmission of the first gear 33 and the second gear 34, and the transmission connection of the third gear 35 to the drive assembly 4, power transmission between the gearbox assembly 3 and the pair of double rocker arm clamping rollers 2 is achieved. The first gear 33 and the second gear 35 have the same number of teeth, ensuring smooth and uniform transmission and avoiding transmission errors and vibrations caused by differences in the number of teeth. Simultaneously, the first connecting shaft 31 is connected to the rocker arm clamping rollers 2 via a universal joint 36. This connection method makes the transmission more flexible, adaptable to clamping requirements at different angles and directions, and improves the applicability and flexibility of the clamping roller device.

[0045] In this application, the second connecting shaft 32 is also connected to the rocker arm pinch roller 21 via a universal joint 36, thereby enabling both the upper and lower double rocker arm pinch rollers 21 to achieve flexible transmission with the gearbox assembly 3 via the universal joint 36. This design not only simplifies the transmission structure but also improves the reliability and stability of the transmission.

[0046] Further, please refer to Figure 3As shown, the drive assembly 4 includes a base 41, a drive motor 42, and a rotating shaft 43. The drive motor 42 is mounted on the base 41, and the rotating shaft 42 is connected to the movable end of the drive motor 42. Furthermore, the rotating shaft 43 is equipped with a fourth gear 44, which meshes with a third gear 35. In practice, when the drive motor 41 of the drive assembly 4 is started, it drives the fourth gear 44 to rotate via the rotating shaft 42. The fourth gear 44 then meshes with the third gear 35, transmitting power to the second connecting shaft 32. Since the first gear 33 and the second gear 34 have the same number of teeth and mesh with each other, the first connecting shaft 31 and the second connecting shaft 32 rotate at the same speed, thereby driving a pair of double-rocker arm clamping rollers 2 to rotate synchronously, achieving stable clamping and conveying of the rolled workpiece.

[0047] In addition, please see Figure 1 As shown, the drive assembly in this embodiment is also equipped with a protective cover 45, which covers the periphery of the rotating shaft 43 to prevent dust, debris, etc. from entering the device and affecting its normal operation. At the same time, the design of the protective cover also enhances the safety of the device, avoiding accidents caused by accidental contact by operators.
