[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a reducer limiter of the utility model comprises a side plate 1, a circular groove 2 is provided on the inner side surface of the side plate 1, grooves 16 are provided on both sides of the circular groove 2, and clamping plates 3 with arc structures are provided in the grooves 16, and a plurality of positioning grooves 15 are distributed in an annular structure on the outer side surface of the side plate 1, and positioning blocks are slidably installed in the positioning grooves 15, and L-shaped plates 5 are installed on the outer side surfaces of the positioning blocks, and a plurality of fixed plates 6 are installed on the inner side surface of one lateral end of the L-shaped plate 5, and rollers 7 are provided between the fixed plates 6, and a reduction mechanism for controlling the rotation speed of the roller 7 is installed on one side of the roller 7, and a driving mechanism for driving the L-shaped plate 5 to synchronously move inward or open outward is installed at the center of the side plate 1.

[0020] In this embodiment, the speed reduction mechanism includes a pressure plate 8, a friction plate 9, an adjustment plate 10, a screw 11, a bearing and a hand wheel 12. The lower end of the fixed plate 6 is embedded with a sealed bearing. The rollers at both ends of the drum 7 are installed in the inner ring of the sealed bearing. The rollers on one side are extended outward and are installed with friction plates 9. The pressure plates 8 are arranged on the outside of the friction plates 9 and are in contact with the friction plates 9. The fixed plate 6 away from the side plate 1 is provided with a positioning hole. One end of the adjustment plate 10 is installed on the pressure plate 8 through the positioning hole. The other end of the adjustment plate 10 is provided with a screw hole. The screw 11 is threadedly connected to the screw hole. A ball bearing is embedded in the fixed plate 6 on one side opposite to the screw 11. One end of the screw 11 is installed in the inner ring of the ball bearing, and the other end is fixedly connected to the hand wheel 12.

[0021] Among them, the pressure plate and the friction plate are both made of metal materials, and the outer surface of the friction plate is provided with anti-slip grooves, which increases the friction between the pressure plate and the friction plate, and can better limit the speed of the steel belt when it is pulled out.

[0022] In this embodiment, the driving mechanism includes a first cylinder 13 and multiple connecting plates 14. One end of the connecting plate 14 is installed on the piston rod of the cylinder through a hinge, and the other end is installed on the L-shaped plate 5 through a hinge. A fixing frame is installed between the first cylinder 13 and the side plate 1.

[0023] In this embodiment, the cross-sections of the positioning groove 15 and the positioning block are both arranged in a trapezoidal structure, so that the L-shaped plate can only move along the positioning groove, thereby avoiding the swing and shaking of the L-shaped plate and increasing the stability during the movement.

[0024] In this embodiment, the outer ring surface of the side plate 1 is provided with an axial hole opposite to the groove 16, and the second cylinder 4 is installed on the outside of the axial hole. The piston rod of the second cylinder 4 passes through the axial hole and is installed on the outer side of the clamping plate.

[0025] When in use, the side plate can be sleeved on one side of the winding disk through the circular groove, and the second cylinder is started to make the piston rod of the second cylinder extend outward. The movement of the piston rod drives the clamping plate, and the side plate can be clamped and fixed on the winding disk through the clamping plate that moves inward.

[0026] After the above is completed, the first cylinder can be started to retract the piston rod of the first cylinder. The movement of the piston rod drives the connecting plate, and the movement of the connecting plate drives the L-shaped plate in linkage, so that the L-shaped plate moves inward along the positioning groove synchronously. The movement of the L-shaped plate drives the fixed plate and the roller until multiple rollers move inward and press on the outermost circle of the rolled steel strip, so that the steel strips can fit together and avoid looseness.

[0027] The rotation speed of the drum can be adjusted according to the speed of pulling out the steel strip. When adjusting, the hand wheel can be rotated, and the rotation of the hand wheel drives the screw rod, and the rotating screw rod can drive the adjusting plate to move along the positioning port. The movement of the adjusting plate drives the pressure plate, and the pressure plate moving toward the friction plate can increase the friction of the friction plate when rotating, thereby reducing the rotation speed of the drum, so as to reduce the speed when the steel strip is pulled out, so that the steel strip can be tightened, avoiding the looseness and affecting the processing quality of the steel strip.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
