[0024] Embodiment 1: In combination with Figures 1 to 10 As shown in the drawings, the present application provides a shaft diameter adjustable steel belt unwinding device, which comprises a distance adjusting support mechanism 200, a disc diameter adjusting mechanism 100 arranged outside the distance adjusting support mechanism 200, a belt surface cleaning mechanism 300 arranged on the distance adjusting support mechanism 200, a belt width adapting mechanism 400 arranged on the distance adjusting support mechanism 200 and located outside the disc diameter adjusting mechanism 100, and a steel belt 500 wound on the belt width adapting mechanism 400; the disc diameter adjusting mechanism 100 moves along the distance adjusting support mechanism 200 to adjust the shaft diameter and the cross-sectional width of the belt width adapting mechanism 400, the belt surface cleaning mechanism 300 is used to remove impurities from the side of the steel belt 500 facing outward before unwinding, and the belt width adapting mechanism 400 unwinds the steel belt 500 after adjusting the shaft diameter and the cross-sectional width.

[0025] The disc diameter adjusting mechanism 100 comprises a booster disc 110 and four load-bearing columns 130 arranged at the inner end of the booster disc 110; The distance adjusting support mechanism 200 comprises a support column 210 arranged at the middle part of the booster disc 110, and four insertion holes 220 are formed at the inner end of the support column 210; The belt width adapting mechanism 400 comprises four guide pads 4604, two protective tools 4602 movably mounted outside the load-bearing columns 130, fixed pins 4601 inserted at the outer end of the protective tools 4602, a winding clamp 460 arranged at the outer end of the protective tools 4602 and located outside the fixed pins 4601, an inner built-in drawer plate 4603 movably mounted in the winding clamp 460, a limiting rail 440 inserted into the insertion hole 220, a third locking bolt 450 mounted in the insertion hole 220 and penetrating into the limiting rail 440, a sliding pad ring 410 movably mounted outside the support column 210, four clamps 4101 fixed outside the sliding pad ring 410, a traction arm 420 movably mounted on the clamps 4101, an inner built-in support frame 430 movably mounted at the other end of the traction arm 420, and the inner built-in support frame 430 is movably mounted in the sliding groove inside the limiting rail 440; The exposed ends of the built-in support frame 430 are equipped with guide rods 4301, two sets of expansion brackets 4302 are movably mounted on the guide rods 4301 and are in a stacked state, and a pressure bracket 4303 is installed on the end of the expansion bracket 4302 away from the guide rod 4301; The other end of the pressure-bearing bracket 4303 is fixedly mounted on the inner wall of the winding fixture 460; There are four groups of eight winding clamps 460, with two in each group. The four groups of winding clamps 460 are used to adjust the shaft diameter of the steel strip 500. An arc-shaped slot is provided inside the winding clamp 460 , and the L-shaped arc-shaped end surfaces at both ends of the built-in drawer plate 4603 are adapted to penetrate into the two arc-shaped slots in the two adjacent winding clamps 460 .

[0026] When the steel strip 500 rewinding device needs to adjust the shaft diameter, pressure is applied to the sliding washer 410. The pressed sliding washer 410 will move relatively along the support column 210. The moved sliding washer 410 and the clamp 4101 outside it will push the traction arm 420. The traction arm 420 will push the built-in support frame 430 and the guide rod 4301 after being pressed outward. The two sets of expansion brackets 4302 in the stacked state will expand at the same angle. Finally, the two sets of expansion brackets 4302 will expand at the same angle and push the two adjacent winding clamps 460 to move along the outside of the built-in drawer plate 4603. Until the two adjacent winding clamps 460 are stretched out to adapt to the steel belt 500 with different cross-sectional widths, at the same time, as the booster disc 110 moves along the support column 210, the four guide pads 4604 that are pressed by the outer inclined surface of the booster disc 110 will be pressurized to adjust the wheelbase. Finally, the bandwidth adaptation mechanism 400 after the shaft diameter and cross-sectional width are adjusted can rewind the steel belt 500.

[0027] Example 2: Combine Figure 4 、 Figure 9 as well as Figure 10 As shown, based on Example 1, the disc diameter control mechanism 100 further includes four first positioning plates 170 fixedly mounted on the inner side of the boosting disc 110, a first base 140 and a second base 150 disposed on the bearing column 130, a reinforcing spring 160 disposed between the first base 140 and the second base 150, and a combination bolt 120 mounted in the boosting disc 110 and the bearing column 130; The adjustable support mechanism 200 further includes four second positioning plates 230 fixedly mounted on the inner ends of the support columns 210. Multiple screw holes are evenly distributed within the second positioning plates 230, each of which contains a first locking bolt 240. The threaded section of the first locking bolt 240 fits within the interior of the first positioning plate 170 to secure the boost plate 110 after it has been laterally moved. The inside of the pressure disc 110 is provided with circumferentially distributed fan-shaped insertion holes, and the uniformly distributed fan-shaped insertion holes are located at the periphery of the central hole of the pressure disc 110; The inside of the protector 4602 is provided with an elliptical slide, and the end of the load-bearing column 130 away from the pressure disc 110 is adapted to penetrate into the elliptical slide.

[0028] Preferably, the four first positioning plates 170 are welded at the inner end of the pressure disc 110. When the four first locking bolts 240 are loosened and removed, the moved pressure disc 110 can help the four first positioning plates 170 slide along the outside of the four second positioning plates 230 until the hole in the inside of the first positioning plate 170 moves to a selected screw hole in the inside of the second positioning plate 230, and then the first locking bolt 240 can be assembled along the screw hole. At this time, the moved pressure disc 110 can provide sufficient stable outward support for the four sets of winding clamps 460; When the shaft diameter of the four sets of winding clamps 460 needs to be restored, the four first locking bolts 240 are removed, and the load-bearing column 130 and the pressure disc 110 subjected to the reverse pressure of the four reinforcing springs 160 are quickly reset.

[0029] Embodiment 3: In combination Figure 7 And Figure 8 As shown in FIG. 3, on the basis of embodiment 1, the belt surface cleaning mechanism 300 includes an outward supporting plate 310 mounted on the supporting column 210, a beam plate 320 arranged in the horizontal groove in the inside of the outward supporting plate 310, a first positioning pin 330 penetrating into the inside of the beam plate 320 and inserted into the inside of the outward supporting plate 310, a sliding seat 340 fixed on the outside of the beam plate 320, a limiting clamp 360 movably mounted in the inside of the sliding seat 340, a second positioning pin 350 penetrating into the inside of the sliding seat 340 and inserted into the limiting clamp 360, a fixed shaft 380 fixedly mounted at the outer end of the beam plate 320, a rotating roller 3801 arranged on the outside of the fixed shaft 380, a moving shaft 370 movably mounted in the slot at the outer end of the beam plate 320, a protective roller 3701 arranged on the outside of the moving shaft 370, and a scraping sheet 3702 fixedly mounted on the protective roller 3701. The protective roller 3701 and the rotating roller 3801 are both in the shape of an I-beam, and the ends of the protective roller 3701 are attached to the outside of the ends of the rotating roller 3801, for providing anti-slip protection for the passing steel belt 500.

[0030] Preferably, the interior of the external support plate 310 is provided with evenly distributed recessed holes adapted to the first positioning pin 330. When the shaft diameters of the four sets of winding clamps 460 are adjusted, the first positioning pin 330 is adjusted to fix a selected recessed hole inside the external support plate 310. At this time, the fixed and extended beam plate 320 can deliver the carried movable shaft 370 and the fixed shaft 380 outward, and the protective roller 3701 and the rotating roller 3801 supported by the movable shaft 370 and the fixed shaft 380 can remove impurities from the passing steel strip 500.

[0031] Example 4: Combine Figures 2 to 10 As shown, in the above embodiment, the outer wall of the sliding washer 410 is provided with four pre-installed grooves 4102, and the fourth positioning plates 4103 are fixedly installed in the pre-installed grooves 4102; The distance adjustment support mechanism 200 also includes four third positioning plates 260 fixedly installed on the inner end of the support column 210, and the interior of the third positioning plate 260 is provided with evenly distributed holes, and the second locking bolt 250 is arranged in the hole. The threaded section of the second locking bolt 250 is adapted to pass through the screw hole inside the fourth positioning plate 4103, and is used to adjust the spacing after the sliding gasket 410 is horizontally moved.

[0032] When the sliding gasket 410 is moved laterally along the support column 210 and the two adjacent winding clamps 460 are adjusted to adjust the cross-sectional width, the steel belt 500 wound on the two adjacent winding clamps 460 can be further adapted and constrained on this basis until the steel belts 500 of different widths are perfectly wound and supported by four sets of winding clamps 460, and the cross-sectional width of the two adjacent winding clamps 460 can be fine-tuned by the second locking bolt 250.

[0033] The working principle and use process of the present invention: The support column 210 is fixed to the transmission shaft of the external driving device in advance so that the device is in a suspended state; After the four first locking bolts 240 are effectively adjusted, the four first locking bolts 240 can be re-entered into the four first positioning plates 170 until the threaded sections of the four first locking bolts 240 are tightened again in the screw holes selected by the four second positioning plates 230. Then the external driving device can drive the support column 210, and the bandwidth adapter mechanism 400 as a whole can rewind the steel belt 500. When the cross-sectional width of the rewound steel strip 500 is different from the initial width of the two adjacent built-in drawer plates 4603 in the device, the four second locking bolts 250 are screwed out, and then a thrust is applied to the sliding washer 410 toward the outward support plate 310. As the sliding washer 410 cooperates with the four fourth positioning plates 4103 to move laterally along the support column 210, the traction arm 420 exerted by the clamp 4101 will pull the built-in support frame 430 to extend inward, thereby obtaining two sets of expansion brackets 430 pressed by the built-in support frame 430 and in a stacked state. 02 will exert an outward expansion force on the two groups of pressure-bearing brackets 4303. Finally, the two winding clamps 460 will expand outward at equal intervals along the two ends of the built-in drawer plate 4603 after being compressed. At this time, the two adjacent winding clamps 460 can rewind the steel strips 500 of different widths. After the cross-sectional widths of the four groups of winding clamps 460 are adjusted, the four second locking bolts 250 can be re-entered into the four third positioning plates 260 until the threaded sections of the second locking bolts 250 are fixed in the screw holes inside the fourth positioning plate 4103. When the above-mentioned components for adapting the cross-sectional width of the steel belt 500 and the axial diameter of the steel belt 500 are adjusted, one end of the steel belt 500 can be passed through the gap between the rotating roller 3801 and the protective roller 3701. At this time, the scraper 3702 fixed on the protective roller 3701 facing the rotating roller 3801 can pressurize and scrape the exposed side of the steel belt 500 before rewinding, thereby preventing the dirt on the exposed surface of the steel belt 500 before rewinding from causing wear to the other side after rewinding.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
