[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a steel coil tensioning structure for an unwinding machine. Figure 1 and Figure 2A steel coil tensioning structure for an unwinding machine includes a plate-shaped floor 1, and a rectangular parallelepiped side plate 2 is fixedly connected to the upper surface of the floor 1, so that the entire device is stably supported and operated by the floor 1 and the side plate 2, and a columnar unwinding shaft 3 is rotatably connected to the side surface of the side plate 2, so that the steel coil is sleeved on the outer surface of the unwinding shaft 3, and the steel coil is unwound by rotating the unwinding shaft 3 during the unwinding process, and then two plate-shaped moving plates 4 are slidably connected to the side surface of the side plate 2, so that the two moving plates 4 slide relative to each other to adjust the distance between the two pressing columns 6, so that It is convenient to be applied to steel coils of any diameter, and to tension them to prevent them from slipping and loosening during the unwinding process, thereby improving the versatility of the device. When the steel coil becomes smaller during the unwinding process, the distance between the two clamping columns 6 can be adjusted to maintain the tensioning effect of the steel coil during the unwinding process. The side surfaces of the two movable plates 4 are elastically slidably connected with U-shaped plates 5, and the inner side walls of the two U-shaped plates 5 are rotatably connected with columnar clamping columns 6. During the tensioning process of the steel coil, the friction caused to the steel coil is reduced by rotating the clamping columns 6, so as to ensure the surface quality of the steel coil.

[0021] Reference Figure 1 A groove-shaped slide groove 11 is opened on the side surface of the side plate 2, and a stud 12 is rotatably connected to the inner wall of the slide groove 11 through a ball screw, and the outer wall of the stud 12 is screwed together with the two plate-shaped movable plates 4, and one end of the stud 12 penetrates the side plate 2 to its side surface and is fixedly connected to the output end of the motor so that the stud 12 can be driven to rotate by the motor, thereby driving the two movable plates 4 to slide relative to each other under the action of the ball screw, so as to quickly adjust the spacing between the two clamping columns 6.

[0022] Reference Figure 2 A columnar support shaft 13 is fixedly connected to the inner wall of the U-shaped plate 5, and a columnar clamping column 6 is rotatably connected to the outer surface of the support shaft 13, so that the clamping column 6 can rotate around the support shaft 13 as the axis during the tensioning process.

[0023] Reference Figure 3A plurality of groove-shaped mounting grooves 7 are provided on the side surface of the movable plate 4, a tubular fixed sleeve 8 is fixedly connected to the inner wall of the mounting groove 7, a columnar sliding column 9 is slidably connected to the inner wall of the fixed sleeve 8, and the other end of the sliding column 9 is fixedly connected to the side surface of the U-shaped plate 5. At the same time, a plurality of return springs 10 are fixedly connected to the side surface of the movable plate 4, and the other end of the return spring 10 is fixedly connected to the side surface of the U-shaped plate 5, and the plurality of mounting grooves 7 and the plurality of fixed sleeves 8 are located inside the plurality of return springs 10, so that when the two clamping columns 6 are slid close to the outer surface of the steel coil, the sliding column 9 is contracted inside the fixed sleeve 8, and the return spring 10 is in a compressed state, so that in the process of unwinding the steel coil, through the reset effect of the return spring 10 and the sliding column 9 sliding outward on the inner wall of the fixed sleeve 8, the unwinding of the steel coil is effectively compressed within a certain range.

[0024] The implementation principle of the steel coil tensioning structure for an uncoiler in the embodiment of the present application is as follows: before the steel coil needs to be uncoiled, the steel coil is first sleeved on the outer surface of the uncoiler shaft 3. During the uncoiler process, the uncoiler shaft 3 will rotate, and then the stud 12 is driven by the motor to rotate, thereby driving the two moving plates 4 to slide relative to each other under the action of the ball screw, so as to quickly adjust the distance between the two clamping columns 6, so that the two clamping columns 6 slide close to the outer surface of the steel coil of any diameter, while the sliding column 9 is contracted inside the fixed sleeve 8, and the reset spring 10 is in a compressed state, so that during the uncoiler process, the steel coil can be tightened. In the process, the steel coil is effectively compressed within a certain range by the reset action of the reset spring 10 and the sliding column 9 sliding outward on the inner wall of the fixed sleeve 8. Then, after a certain amount of unwinding, when the diameter of the steel coil decreases within a certain range, the two movable plates 4 drive the two compression columns 6 to slide relative to each other to maintain the tensioning effect of the steel coil during the unwinding process, so that it is suitable for steel coils of any diameter to be tensioned. When the steel coil becomes smaller during the unwinding process, the distance between the two compression columns 6 can be adjusted to ensure the tensioning effect of the steel coil at all times.
