[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Strip steel is also known as steel strip. Its width is within 1300mm, and its length varies slightly depending on the size of each coil. In the strip steel production process, the stability and accurate control of strip steel tension is crucial to product quality, and strip steel tensioning devices are required.
[0003] Currently, some existing strip tensioning devices are very cumbersome to adjust, requiring staff to perform complex manual operations, which causes inconvenience for the staff. At the same time, manual operation is difficult to ensure that each adjustment is accurate, which can easily lead to deviations that affect the strip and reduce the practicality of the device.
[0004] Meanwhile, some existing strip tensioning devices cannot limit the strip during operation, which can cause wrinkles and jamming. In severe cases, this can damage the device, shorten its service life, and cause economic losses during repair. Damage can also reduce work efficiency. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 As shown, a conveniently adjustable strip tension device includes a workbench 1. An adjustment box 2 is fixedly connected to the top of the workbench 1. A motor 3 is fixedly connected to one side of the adjustment box 2. A transmission rod 4 is fixedly connected to the output end of the motor 3. A winding drum 5 is fixedly connected to the outer surface of the transmission rod 4. The motor 3 drives the winding drum 5 and the transmission rod 4 to rotate for winding. An adjustment mechanism 8 is installed on one side of the inner cavity of the adjustment box 2. An adjustment roller 10 is movably connected to one side of the adjustment mechanism 8 via a bearing. Through the cooperation of the adjustment mechanism 8 and the adjustment roller 10, the tension can be automatically adjusted to the required height as needed, reducing the trouble for the operator and improving the practicality of the device. A limiting shell 6 is fixedly connected to one side of the top of the workbench 1. A limiting mechanism 9 is installed on one side of the inner cavity of the limiting shell 6. A limiting roller 7 is movably connected to one side of the limiting mechanism 9 via a bearing. Through the cooperation of the limiting mechanism 9 and the limiting roller 7, the passing strip can be limited, keeping it in a flat state for operation and preventing jamming of the device, thereby preventing damage to the device.
[0023] The adjustment mechanism 8 includes a first cylinder 801 fixedly connected to one side of the inner cavity of the adjustment box 2. A triangular plate 802 is fixedly connected to the output end of the first cylinder 801. A guide groove 803 is provided on the inner surface of the triangular plate 802. An adjustment rod 804 is movably connected to the inner surface of the triangular plate 802 through the guide groove 803. The adjustment rod 804 is rotatably connected to the adjustment roller 10. Through the adjustment mechanism 8, the first cylinder 801 pushes the triangular plate 802 to move left and right. The triangular plate 802 drives the adjustment rod 804 to move up and down through the inclined surface of the guide groove 803. The adjustment rod 804 drives the adjustment roller 10 to move up and down. When the adjustment roller 10 is raised, the wrap angle of the strip on the winding drum 5 increases, and the strip tension increases. Conversely, when the height of the adjustment roller 10 is lowered, the wrap angle decreases, and the tension decreases. The tension can be automatically adjusted to the required height as needed, reducing the trouble for the workers and improving the practicality of the device.
[0024] The limiting mechanism 9 includes a second cylinder 901 fixedly connected to the top and bottom of the inner cavity of the limiting shell 6. A connecting plate 902 is fixedly connected to the output end of the second cylinder 901. A first sliding sleeve 904 is fixedly connected to one side of the connecting plate 902. A first sliding rod 903 is slidably connected to the inner surface of the first sliding sleeve 904. A movable plate 905 is fixedly connected to one side of the first sliding sleeve 904. The movable plate 905 is rotatably connected to the limiting roller 7. Through the limiting mechanism 9, the second cylinder 901 pushes the connecting plate 902 to one side. The connecting plate 902 drives the first sliding sleeve 904 to slide to one side on the outer surface of the first sliding rod 903. The first sliding sleeve 904 drives the movable plate 905 to one side. The movable plate 905 drives the limiting roller 7 to one side. This can limit the passing strip steel, keep it in a flat state for operation, prevent jamming of the device, and thus prevent damage to the device. At the same time, it can limit strip steel of different thicknesses.
[0025] The inner surface of the adjusting rod 804 is slidably connected to a second slide rod 12. The top and bottom of the second slide rod 12 are fixedly connected to the top and bottom of the inner cavity of the adjusting box 2. By setting the second slide rod 12, the adjusting rod 804 can move up and down more stably, thereby making the tension adjustment more stable.
[0026] The inner cavity of the adjustment box 2 is fixedly connected to the two sides of the third slide rod 14. The outer surface of the third slide rod 14 is slidably connected to the second slide sleeve 13. The top of the second slide sleeve 13 is fixedly connected to the bottom of the triangle plate 802. The second slide sleeve 13 and the third slide rod 14 can support the triangle plate 802, thereby improving the stability of the triangle plate 802 when it moves left and right.
[0027] A controller 11 is fixedly installed on one side of the top of the workbench 1. The output of the controller 11 is electrically connected to the input of the motor 3. The speed of the motor 3 can be controlled by the controller 11. The motor 3 can be adjusted to a suitable speed according to the required tension to prevent deviation.
[0028] It is worth noting that the technical features proposed in this technical solution, such as motor 3, controller 11, winding drum 5, first cylinder 801 and second cylinder 901, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.
[0029] Working principle: First, the strip steel passes through the inner side of the limiting roller 7. Then, the second cylinder 901 is opened, pushing the connecting plate 902 to one side. The connecting plate 902 drives the first sliding sleeve 904 to slide to one side on the outer surface of the first sliding rod 903. The first sliding sleeve 904 drives the movable plate 905 to one side, and the movable plate 905 drives the limiting roller 7 to one side. This can limit the passing strip steel and keep it flat. At the same time, it can limit different strip steels. The passing strip steel is simultaneously located above the adjusting roller 10. Then, the first cylinder 901 is opened. Cylinder 801 pushes triangular plate 802 to move left and right. Triangular plate 802 drives adjusting rod 804 to move up and down through the inclined surface of guide groove 803. Adjusting rod 804 drives adjusting roller 10 to move up and down. When adjusting roller 10 is raised, the wrap angle of the strip on the winding drum 5 increases, and the tension of the strip increases. Conversely, when the height of adjusting roller 10 is lowered, the wrap angle decreases, and the tension decreases. Then, one end of the strip is placed on the winding drum 5. Motor 3 is turned on through controller 11. Motor 3 drives winding drum 5 and transmission rod 4 to rotate for winding.
