DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The embodiment of the present application discloses a cold-rolled steel plate unwinding device.

[0030] refer to Figure 1 The cold-rolled steel plate unwinding device includes an equipment body 1, a sliding cylinder 2, a main rod 3, a tension spring 42 and a hook plate 4. The sliding cylinder 2 is installed on the top of the back of the equipment body 1, and the main rod 3 is slidably connected in the sliding cylinder 2. A cross bar 31 is horizontally arranged on the top of the main rod 3, and the cross bar 31 is located above the steel coil placed on the equipment body 1. Two rotating frames 311 are rotatably connected at the bottom of the cross bar 31, and a pressure roller 3112 is rotatably connected at the bottom of the rotating frame 311. A plurality of clamping springs 3111 are arranged between the two rotating frames 311, so that the two rotating frames 311 are close to each other.

[0031] refer to Figure 2 and Figure 3 The tension spring 42 is installed at the bottom of the back of the equipment body 1, just below the sliding cylinder 2. The hook plate is installed at the top of the tension spring 42, and the side wall at the bottom end of the main rod 3 is provided with a hook groove 32, and the hook plate can be hooked in the hook groove 32, at which time the tension spring 42 is in a tensioned state.

[0032] After the steel coil is mounted on the rotating roller of the equipment body 1, the main rod 3 is moved so that the pressure roller 3112 abuts against the steel coil, and then the hook plate 4 is pulled so that the hook plate 4 is hooked in the hook groove 32. Then, the cross bar 31 is pressed against the steel coil by the tensioning force of the tension spring 42, and the tensioning force of the two rotating frames 311 is cooperated so that the two pressure rollers 3112 can always be pressed against the steel coil, thereby improving the stability and safety of the cold-rolled steel coil during unwinding.

[0033] refer to Figure 3The side wall of the sliding cylinder 2 is provided with a mounting hole 21, and the main rod 3 is provided with a positioning hole 33 that can be connected to the mounting hole 21. A positioning rod 5 is inserted into the mounting hole 21, and the positioning rod 5 is threadedly connected to the positioning hole 33. When the positioning rod 5 is located in the positioning hole 33 and the mounting hole 21 at the same time, the pressure roller 3112 does not abut against the steel coil placed on the equipment body 1. The hook plate is provided with a connecting hole 41, and the bottom side wall of the main rod 3 is provided with a connecting groove 34 that is connected to the connecting hole 41. The positioning rod 5 can also pass through the connecting hole 41 and be threadedly connected to the connecting groove 34. A back door 6 is rotatably connected to the back of the equipment body 1. After the back door 6 is closed, it can shield the hook plate 4 and the tension spring 42 and abut against the hook plate.

[0034] When the steel coil is not placed, the positioning rod 5 can be inserted into the mounting hole 21 and the positioning hole 33 at the same time to fix the position of the main rod 3, thereby facilitating the placement and removal of the steel coil. After the hook plate 4 is hung on the main rod 3, the positioning rod 5 is inserted into the connecting hole 41 and the connecting groove 34 at the same time to improve the stability of the connection between the hook plate 4 and the main rod 3. Closing the back door 6 at the same time can effectively reduce the probability of the tension spring 42 popping out and splashing after it is loosened, and can also protect the tension spring 42. The abutment relationship of the back door 6 can also improve the stability of the position of the hook plate 4.

[0035] The implementation principle of the cold-rolled steel plate unwinding device of the embodiment of the present application is as follows: after the steel coil is placed on the equipment body 1, the main rod 3 is pulled down by hooking the hook plate 4 in the hook groove 32, so that the pressure roller 3112 is always pressed against the top of the steel coil, and then the positioning rod 5 is inserted into the connection hole 41 and the connection groove 34 at the same time to improve the stability of the connection between the hook plate 4 and the main rod 3, and finally the back door 6 is closed. In this way, the steel coil can maintain a stable unwinding rotation on the equipment body 1 after being thinned, thereby improving the stability and safety during the unwinding process.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
