At the same time, the drive motor drives the winding cavity to rotate through the transmission gear and transmission ring. With the assistance of the first positioning roller and the second positioning roller, the winding and shaping are completed. By winding gradually inward from the outside to the inside relying on the elasticity of the strip steel itself, the wear of the auxiliary rollers on the surface of the strip steel body in the existing equipment is reduced, and the product quality is improved.

[0016] By adopting the above technical solution, multiple sets of second positioning rollers work together to guide the strip body and send the strip to the outside for winding and shaping.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figures 1 to 3The diagram illustrates a strip steel winding device from the outside in, comprising a winding cavity 1. A winding assembly is disposed inside the winding cavity 1. The winding assembly includes a first positioning roller 11, a winding platform 13, a transmission gear ring 14, an annular guide rail 15, a drive motor 16, a transmission gear 17, a support plate 2, a guide plate 21, a second positioning roller 23, a first guide roller 24, a second guide roller 26, a servo motor 28, a connecting turntable 29, and a feeding wheel 210. The winding platform 13 is fixedly connected to the inner wall of the winding cavity 1. The inner side of the winding cavity 1 winds up the strip steel body 3. The support plate 2... Plate 2 is positioned at the center of winding platform 13. An annular guide rail 15 is provided on the lower side of winding cavity 1. The lower end of winding cavity 1 is rotatably connected to annular guide rail 15. Transmission gear ring 14 is fixedly connected to the surface of winding cavity 1. Drive motor 16 is fixedly mounted on the side of annular guide rail 15. The output end of drive motor 16 is fixedly connected to transmission gear 17. Transmission gear 17 meshes with transmission gear ring 14. Connecting frames 12 are rotatably connected to both the upper and lower ends of the first positioning roller 11. Connecting frames 12 are fixedly connected to the inner wall of winding cavity 1.

[0031] The feeding roller 210 is inclined to facilitate the conveying of the strip body 3 to the inside of the winding chamber 1. At this time, the first guide roller 24 and the two sets of second guide rollers 26 cooperate with the feeding roller 210 to convey the strip body 3 to the inside of the winding chamber 1. Meanwhile, the drive motor 16 drives the winding chamber 1 to rotate through the transmission gear 17 and the transmission gear ring 14. During the rotation of the winding chamber 1, the winding platform 13 rotates around the side of the support plate 2. With the assistance of the first positioning roller 11 and the second positioning roller 23, the winding and shaping are completed. At the same time, the first positioning roller 11 and the second positioning roller 23 reduce the wear of the strip body 3 and improve the strip winding efficiency and winding quality.

[0032] See Figure 1 , Figures 3 to 5 Two sets of guide plates 21 are fixedly connected to the edge of the upper surface of the support plate 2. The first guide roller 24 is rotatably connected to the upper end of the two sets of guide plates 21. Connecting plates 25 are fixedly connected to the upper and lower sides of the inner surface of the two sets of guide plates 21. The two sets of connecting plates 25 on the same side are rotatably connected to the upper and lower sets of connecting plates 25. An inclined mounting base 27 is fixedly connected to the middle of the upper surface of the support plate 2. The connecting turntable 29 is rotatably connected to the upper surface of the mounting base 27. The feeding turntable 210 is fixedly connected to the upper surface of the connecting turntable 29. The servo motor 28 is fixedly installed at the bottom of the support plate 2. The output end of the servo motor 28 is coaxially fixedly connected to the connecting turntable 29. An annular inner rolling bracket 22 is fixedly connected to the outer side of the two sets of guide plates 21. Multiple sets of second positioning rollers 23 are rotatably connected between the inner rolling bracket 22 and the support plate 2.

[0033] Specifically, during the winding process, the strip body 3 is first passed through the gap between the two sets of second guide rollers 26, then the strip body 3 is passed around the feed roller 210, and then passed through the second positioning roller 23 and fed into the winding cavity 1. As the servo motor 28 drives the feed roller 210 to rotate, the strip body 3 is continuously fed into the winding cavity 1. At this time, the end of the strip body 3 will slide against the multiple sets of first positioning rollers 11 at the edge until the strip body 3 is fully wound. Then the second turn will press the surface of the first turn. At this time, the drive motor 16 is started. The output end of the drive motor 16 drives the transmission gear 17 to rotate. The transmission gear 17 drives the winding cavity 1 to rotate on the upper side of the annular guide rail 15 through the transmission gear ring 14, continuously winding the strip body 3. At the same time, under the action of its own elasticity, the strip body 3 will gradually wind inward, so that it is wound from the outside to the inside, and the two layers of strip body 3 are tightly attached.

[0034] The working principle of this utility model is as follows: The strip body 3 is conveyed into the winding cavity 1 by the cooperation of the servo motor 28, the feeding wheel 210, the first guide roller 24 and the second guide roller 26. At the same time, the drive motor 16 drives the winding cavity 1 to rotate through the transmission gear 17 and the transmission gear ring 14. With the assistance of the first positioning roller 11 and the second positioning roller 23, the winding and shaping are completed. The strip body 3 is wound from the outside to the inside by relying on its own elasticity, so that the inner and outer sides of the strip body 3 are tightly attached. It is not necessary to use auxiliary rollers to press the strip body 3, thereby reducing the wear of the auxiliary rollers on the surface of the strip body 3 and improving the quality of the strip body 3.
