[0019] It should be noted that the inflatable shaft 22 belongs to the prior art and will not be described in detail here.

[0020] like Figure 4 As shown, the cross-section of the tile is an arc-shaped surface, and the curvature of the tile 23 is adapted to the curvature of the circumferential direction of the inflatable shaft 22. A plurality of arc-shaped grooves 231 are provided on the surface of the tile 23. Two to six tiles 23 can be provided. Each tile 23 forms a circle on the outer circumferential surface of the inflatable shaft 22, so that the arc-shaped grooves 231 corresponding to each tile 23 form a circle of annular grooves. The separator 24 is annular, and the separator 24 is detachably sleeved in the annular groove.

[0021] like Figure 1 As shown, the rotating shaft 21 is provided with a bearing, and the bearing is connected to the frame 1, so that the utility model is connected to the rolling shear body. Figures 1 to 3 As shown, the utility model also includes a clamping mechanism, which includes a connecting bracket 31, a pressure wheel frame 32, a separation roller 33, a pressure wheel 34 and a cylinder 35. The connecting bracket 31 is connected to the rolling shear body 1, the cylinder 35 is connected to the connecting bracket 31, the pressure wheel frame 32 is connected to the movable end of the cylinder 35, the separation roller 33 is pivotally connected to the pressure wheel frame 32, and the separation roller 33 is provided with a pressure wheel 34, and a plurality of pressure wheels 34 are provided, and each pressure wheel 34 corresponds to the interval position between each separation sheet 24, and each pressure wheel 34 is respectively located above the interval between each separation sheet 24. The action of the cylinder 35 can drive the pressure wheel 34 to press down. The connecting bracket 31 is provided with a guide rod 36, the guide rod 36 is slidably connected to the connecting bracket 31, and the lower end of the guide rod 36 is connected to the pressure wheel frame 32.

[0022] The method of using the utility model is as follows: Figure 1 and Figure 5As shown, the utility model is installed on the rolling shear body 1, the inflatable shaft 22 is inflated, the rubber airbag 222 is inflated, the key strip 223 of the inflatable shaft 22 protrudes from the surface of the shell 221 of the inflatable shaft 22, and because the tile 23 is connected to the key strip 223, each tile 23 forms a propped circular structure, and the separator 24 is engaged with the annular groove formed by the tile 23. At this time, the separator 24 is in a locked state, and the rolling shear cuts a steel strip into multiple steel strips 4, and each steel strip is rolled into each interval formed between each separator 24 on the tile 23. The rotating shaft 21 rotates, thereby rolling each steel strip 4 to form a steel strip roll. When the rolling is completed, the rotating shaft 21 stops rotating, and the cylinder 35 of the clamping mechanism is actuated to press the pressure wheel frame 32 downward, so that the pressure wheel 32 is pressed into each interval, and the pressure wheel 32 presses the steel strip roll, so that the inflatable shaft stops rotating immediately, which is convenient for cutting the steel strip. The air shaft is deflated, the rubber airbag 222 shrinks, and the key strip 223 of the air shaft 22 retracts into the shell 221 of the air shaft 22, so that each tile 23 forms a contracted circular structure. At this time, the rolled steel strip and the separator can be removed one by one along the free end of the air shaft. The whole process is simple and convenient. When it is necessary to roll again, first install the separator into the corresponding annular slot, and then inflate the air shaft again, and repeat the above steps.

[0023] It can be seen from the above description that the utility model can lock the separator by inflating the inflatable shaft, thereby forming a gap to facilitate the winding of each material strip, and the material roll and the separator can be disassembled along the free end of the inflatable shaft by deflating the inflatable shaft. Compared with the prior art, there is no need to disassemble the winding rod, nor is it necessary to use tools to disassemble the material roll on the winding roller. The disassembly process is simple and convenient. By setting a clamping mechanism to clamp the material roll, the inflatable shaft can quickly stop rotating, which is convenient for cutting the material strip.

[0024] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
