[0022] A support base plate 12 is provided above the bottom support block 1, located between the first mounting block 2 and the second mounting block 3. The steel strip passes over the bottom support base plate 12, which provides support for the steel strip. A first spring 13 is fixed to each of the four corners of the bottom of the support base plate 12, with the bottom of the first spring 13 fixed to the top surface of the bottom support block 1. With the first springs 13 in place, even after some wear on the top surface of the support base plate 12, the support base plate 12 can still support the steel strip under the action of the first springs 13. A placement groove 14 is provided on the top surface of the support base plate 12, and a rotating roller 15 is rotatably connected to the placement groove 14. The rotating roller 15 reduces the friction between the support base plate 12 and the steel strip.

[0023] Reference Figure 1Two sets of limiting rollers 16 are provided on the bottom support block 1. One set of limiting rollers 16 is located on one side of the bottom support block 1, and the other set of limiting rollers 16 is located on the other side of the bottom support block 1.

Both ends of the limiting rollers 16 are provided with fixing plates 17, and the limiting rollers 16 are rotatably connected to the fixing plates 17.

[0024] The working principle of this utility model's steel strip slitting limiting device is as follows: Before the steel strip enters the steel strip slitting machine, it passes through the guide limiting sleeve 4 on the first mounting block 2 and the second mounting block 3, thereby limiting the swing of the steel strip in the width direction, ensuring accurate cutting by the steel strip slitting machine, and improving the utilization rate of the steel strip. After prolonged use, the surface of the guide limiting sleeve 4 may become damaged, requiring replacement. During replacement, the locking bolt 81 is removed, the guide limiting sleeve 4 is removed from the connecting column 23, and a new guide limiting sleeve 4 is installed.

[0025] Embodiment 2 of this utility model Reference Figure 6 and Figure 7 The difference from Embodiment 1 is that the locking assembly 8 includes a pressing block 82, a first connecting plate 83 and a second connecting plate 84. The first connecting plate 83 is fixed to the side wall of the first mounting block 2. The top of the first connecting plate 83 is provided with a receiving groove 831.

[0026] A first insertion hole 833 is provided on the side wall of the first connecting plate 83, and a second insertion hole 841 is provided on the second connecting plate 84. A locking pin 834 is provided on the first connecting plate 83, and the locking pin 834 passes through the first insertion hole 833 and is inserted into the second insertion hole 841. When fixing the mounting plate 7, the insertion hole 71 on the mounting plate 7 is aligned with the corresponding insertion block 24, so that the insertion block 24 is inserted into the insertion hole 71. Then, the pressing block 82 is pressed down, and the second connecting plate 84 presses the second spring 832. When the second insertion hole 841 is aligned with the first insertion hole 833, the locking pin 834 is inserted into the first insertion hole 833 and the second insertion hole 841. When the second insertion hole 841 is aligned with the first insertion hole 833, the pressing block 82 presses the mounting plate 7.

[0027] When disassembling the mounting plate 7, the locking pin 834 is pulled out. Under the action of the second spring 832, the second connecting plate 84 automatically moves upward, thereby disengaging the clamping block 82 from the top of the mounting plate 7. Then, the mounting plate 7 is pulled upward to disengage it from the insertion block 24. The mounting plate 7 is fixed by the locking assembly 8, which facilitates the installation and disassembly of the mounting plate 7 and the replacement of the guide limit sleeve 4.
