[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1: As Figures 1-8 As shown in the embodiment of the present invention, a steel strip cutting and winding device includes a first cylinder 1, with first rings 12 respectively arranged on both sides of the first cylinder 1, a second ring 121 rotatably arranged in the middle of the first ring 12, the first cylinder 1 slidably arranged inside the second ring 121, and third rings 13 respectively arranged on the outer sides of both ends of the first cylinder 1. An arc plate 132 is fixed between the upper ends of the two third rings 13, and a plurality of fourth rings 131 are fixed to the lower end of the arc plate 132 through an arc block 133. The first cylinder 1 is rotatably arranged between the plurality of fourth rings 131. A cutting assembly is arranged on one side of the first cylinder 1. The cutting assembly includes a first cylindrical wheel 2 rotatably arranged on one side of the first cylinder 1, a second cylindrical wheel 22 rotatably arranged at the lower end of the first cylindrical wheel 2, a plurality of circular cutting blades 21 arranged on the outer side of the first cylindrical wheel 2, and grooves 221 respectively opened on the outer side of the second cylindrical wheel 22 corresponding to the positions of the circular cutting blades 21.

[0032] Specifically, depending on production needs, some steel strips need to be slit and then wound after production. When the steel strip is slit into several narrow strips, and these strips are wound simultaneously, the sides of the coiled steel strip may become uneven or even misaligned, affecting the winding efficiency and effect. In this winding device, the processed steel strip is placed between the first cylindrical wheel 2 and the second cylindrical wheel 22. The circular cutting blade 21 slits the steel strip, and the ends of the slit strips are respectively installed on the side of the first cylinder 1, so that each slit strip is located between the fourth ring 131. By driving the first cylinder 1 to rotate in the middle of the fourth ring 131, the slit steel strips are wound around the outside of the first cylinder 1. The fourth ring 131 limits the movement of the slit steel strips. When the strips are wound up simultaneously, the sides of each roll of steel strip are kept neat. When several rolls of steel strip need to be removed, they are bundled together, and the first cylinder 1 is driven to slide to one side in the middle of the fourth ring 131, so that the first cylinder 1 gradually separates from the middle of each fourth ring 131. Then the rolls of steel strip are taken out from between the fourth rings 131 in sequence. When winding up multiple slit steel strips, multiple fourth rings 131 are set on the outside of the first cylinder 1, so that each slit steel strip is located between the fourth rings 131. By driving the first cylinder 1 to rotate in the middle of the fourth ring 131, the slit steel strip is wound around the outside of the first cylinder 1. The fourth rings 131 limit the slit steel strip. This solves the problem that when winding up several narrow steel strips at the same time, the sides of the rolled steel strips may be uneven or even mis-layered, which affects the winding efficiency and winding effect.

[0033] like Figures 1-2 As shown, a base plate 6 is provided at the lower end of the first cylinder 1, the first ring 12 is fixed to the upper end of the base plate 6 through the first support plate 122, and the third ring 13 is fixed to the upper end of the base plate 6 through the second support plate 134. A rectangular groove 11 is provided on the outer side of the first cylinder 1, and a protrusion is provided on the inner side of the second ring 121 corresponding to the position of the rectangular groove 11. The first cylinder 1 slides on the outer side of the protrusion through the rectangular groove 11.

[0034] Specifically, the second ring 121 is electrically driven and can rotate in the middle of the first ring 12. The protrusion on the inner side of the first ring 12 is locked in the rectangular groove 11. When the second ring 121 rotates, it drives the first cylinder 1 to rotate in the middle of the fourth ring 131 to wind up the steel strip. After winding, the first cylinder 1 is driven to slide to one side. The first cylinder 1 slides outside the protrusion through the rectangular groove 11, so that the first cylinder 1 gradually separates from the middle of each fourth ring 131. Then the coiled steel strip is taken out from between the fourth rings 131 in sequence.

[0035] like Figure 2 As shown, an arc-shaped groove 16 is provided on the upper outer side of the first cylinder 1 corresponding to the side of the cutting component. A clamping device is provided inside the arc-shaped groove 16, which is used to clamp the end of the steel strip.

[0036] Specifically, the ends of the slit steel strips are placed inside the arc-shaped groove 16, and the ends of the steel strips are fixed by the clamping device. Then, the first cylinder 1 is driven to rotate, which causes the steel strip to be wound around the outside of the first cylinder 1. The clamping device is an existing elastic component that squeezes and fixes the ends of the steel strips.

[0037] like Figure 6 As shown, a second cylinder 14 is provided at one end of the first cylinder 1. The second cylinder 14 has the same structure as the first cylinder 1. A gap is provided between the second cylinder 14 and the first cylinder 1. Rectangular plates 15 are fixedly connected to the opposite ends of the second cylinder 14 and the first cylinder 1. The upper ends of the two rectangular plates 15 are fixedly connected by a U-shaped frame 151. Electric slide tables 152 are fixedly connected to the lower ends of the rectangular plates 15. Electric slide rails 153 are fixedly connected to the upper end of the base plate 6 at the positions corresponding to the electric slide tables 152. The electric slide tables 152 are slidably arranged on the upper ends of the electric slide rails 153.

[0038] Specifically, by driving the electric slide table 152 to slide on the upper end of the electric slide rail 153, the electric slide table 152 drives the first cylinder 1 and the second cylinder 14 to slide in the same direction simultaneously through the rectangular plate 15. A certain gap is provided between the first cylinder 1 and the second cylinder 14. When the first cylinder 1 slides to one side in the middle of the fourth ring 131, it simultaneously drives the second cylinder 14 to slide towards the middle of the fourth ring 131. The steel strip rolled on the outside of the first cylinder 1 can be taken out from the gap between the first cylinder 1 and the second cylinder 14. After the second cylinder 14 has completely slid to the middle of the fourth ring 131, the above steps can be repeated to rewind the steel strip to the outside of the second cylinder 14.

[0039] like Figure 5 As shown, a cutting assembly is provided between the first cylinder 1 and the first cylindrical wheel 2. The cutting assembly includes a cutting blade 5 that is slidably disposed on the upper end of the base plate 6. A third support platform 52 is fixedly connected to the upper end of the base plate 6 at the position corresponding to the cutting blade 5. A blade holder 51 is fixedly connected to the upper end of the third support platform 52 at the position corresponding to the cutting blade 5. The output ends of a third electric telescopic rod 53 are fixedly connected to the lower sides of both ends of the cutting blade 5. The third electric telescopic rod 53 is fixedly connected to the upper end of the third support platform 52.

[0040] Specifically, after the steel strip is wound up, the third electric telescopic rod 53 is retracted, causing the cutting blade 5 to slide downwards, so that the cutting blade 5 contacts the lower blade holder 51 and cuts the steel strip. Then the cut end is wound up, and after winding up, it is removed so that the next round of winding can be carried out.

[0041] like Figures 3-4 As shown, extrusion wheels 17 are respectively provided at the upper ends of several fourth rings 131. Rectangular holes 1321 are respectively opened in the middle of the arc plate 132 corresponding to the position of the extrusion wheels 17. Rectangular strips 171 are slidably arranged inside the rectangular holes 1321. The extrusion wheels 17 are respectively rotatably arranged at the lower ends of the corresponding rectangular strips 171. The upper ends of the rectangular strips 171 are all fixedly connected to the I-shaped plate 172. The output ends of the first electric telescopic rod 173 are respectively fixedly connected to the four corners of the lower end of the I-shaped plate 172. The first electric telescopic rod 173 is fixedly connected to the upper end of the base plate 6.

[0042] Specifically, after the coiling is completed and the steel strip is cut, the first electric telescopic rod 173 is retracted, which drives the I-shaped plate 172 to move downward. The I-shaped plate 172 slides downward inside the rectangular hole 1321 through the rectangular bar 171. The rectangular bar 171 drives the extrusion wheel 17 to move closer to the first cylinder 1 until the extrusion wheel 17 is in close contact with the upper end of the coiled steel strip on the outside of the first cylinder 1. The extrusion wheel 17 is in close contact with the outside of the coiled steel strip. Then the first cylinder 1 is driven to rotate to coil the last section of the cut steel strip to prevent the steel strip from loosening.

[0043] like Figure 3 As shown, an arc-shaped collecting frame 18 is fixed to the upper end of the base plate 6 at the position corresponding to the first cylinder 1, and a flexible material is provided inside the arc-shaped collecting frame 18.

[0044] Specifically, when the first cylinder 1 slides to one side in the middle of the fourth ring 131, it simultaneously drives the second cylinder 14 to slide in the middle of the fourth ring 131. The rolled steel strip on the outside of the first cylinder 1 can fall into the arc-shaped collection frame 18 through the gap between the first cylinder 1 and the second cylinder 14. The flexible material inside the arc-shaped collection frame 18 can be a sponge to hold the rolled steel strip that has been bumped and rolled up.

[0045] like Figure 7 As shown, a first adjustment component is provided at the lower end of the first cylindrical wheel 2. The first adjustment component includes a first support platform 25 fixed to the upper end of the base plate 6. A first rectangular frame 23 is fixed to both sides of the upper end of the first support platform 25. A first rectangular block 24 is rotatably provided at both ends of the first cylindrical wheel 2 and the second cylindrical wheel 22. The first rectangular block 24 is slidably provided on one side of the first rectangular frame 23. A cylindrical rod 241 slides through the middle of the two first rectangular blocks 24. A connecting plate 242 is fixed to the upper end of the two cylindrical rods 241. The first adjustment component is used to adjust the distance between the first cylindrical wheel 2 and the second cylindrical wheel 22.

[0046] Specifically, by driving the first rectangular block 24 to slide on the outside of the cylindrical rod 241, the first rectangular block 24 drives the first cylindrical wheel 2 to slide downward on one side of the first rectangular frame 23, so that the first cylindrical wheel 2 drives the circular cutting blade 21 to slide downward, and cuts the steel strip between the first cylindrical wheel 2 and the second cylindrical wheel 22.

[0047] like Figure 8 As shown, a pressing assembly is provided between the cutting blade 5 and the first cylindrical wheel 2. The pressing assembly includes two fourth cylindrical wheels 3 that rotate at the upper end of the base plate 6. A second adjusting assembly is provided at the lower end of the fourth cylindrical wheels 3. The second adjusting assembly has the same structure as the first adjusting assembly. The second adjusting assembly is used to adjust the distance between the two fourth cylindrical wheels 3. U-shaped frames 31 are provided on both sides of the fourth cylindrical wheels 3. The U-shaped frames 31 are fixed to the upper end of the second adjusting assembly. Several cylindrical strips 311 are fixed to the lower end of the U-shaped frames 31.

[0048] Specifically, the cut steel strip will have curled edges on the sides. The cut steel strip is placed between two fourth cylindrical wheels 3, and then the second adjustment component is driven to move the two fourth cylindrical wheels 3 closer to each other to squeeze the cut steel strip in the middle. At the same time, the cut steel strip is placed between each cylindrical strip 311 to prevent the cut steel strip from overlapping and to squeeze the cut steel strip to prevent the sides of the cut steel strip from curling.

[0049] Example 2: Figure 5 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a tension adjustment assembly is provided between the fourth cylindrical wheel 3 and the first cylindrical wheel 2. The tension adjustment assembly includes a third cylindrical wheel 4 rotatably disposed on the upper end of the base plate 6. A second support platform 41 is fixedly connected to the upper end of the base plate 6 at the position corresponding to the third cylindrical wheel 4. A second rectangular frame 42 is fixedly connected to both sides of the upper end of the second support platform 41. A second rectangular block 43 is rotatably disposed at both ends of the second support platform 41. The second rectangular block 43 is slidably disposed on one side of the second rectangular frame 42. The lower end of the second rectangular block 43 is fixedly connected to the output end of the second electric telescopic rod 44. The second electric telescopic rod 44 is fixedly connected to the upper end of the second support platform 41.

[0050] Specifically, when winding up the slit steel strip, the second electric telescopic rod 44 is driven to retract. The second electric telescopic rod 44 drives the third cylindrical wheel 4 to move downward through the second rectangular block 43, so that the third cylindrical wheel 4 is pressed tightly against one side of the steel strip, squeezing the steel strip and keeping the steel strip taut at all times.

[0051] Working principle: When using this winding device, the processed steel strip is placed between the first cylindrical wheel 2 and the second cylindrical wheel 22. The first rectangular block 24 is driven to slide on the outside of the cylindrical rod 241. The first rectangular block 24 drives the first cylindrical wheel 2 to slide downward on one side of the first rectangular frame 23, so that the first cylindrical wheel 2 drives the circular cutting blade 21 to slide downward. The circular cutting blade 21 cuts the steel strip. Then the cut steel strip is placed between the two fourth cylindrical wheels 3. Then the second adjusting component is driven to drive the two fourth cylindrical wheels 3 to move closer to each other and squeeze the cut steel strip in the middle. At the same time, the cut steel strip is placed between each cylindrical bar 311 to prevent the cut steel strip from overlapping. The cut steel strip is squeezed to prevent the sides of the cut steel strip from curling up.

[0052] The ends of the slit steel strips are placed inside the arc-shaped grooves 16 and fixed by a clamping device. The second ring 121 is electrically driven and can rotate in the middle of the first ring 12. The protrusions on the inner side of the first ring 12 are engaged in the rectangular groove 11. When the second ring 121 rotates, it drives the first cylinder 1 to rotate in the middle of the fourth ring 131, thus winding up the steel strip. After the steel strip is wound up, the third electric telescopic rod 53 is retracted, causing the cutting blade 5 to slide downwards, so that the cutting blade 5 contacts the lower blade holder 51 and cuts the steel strip. The steel strip is cut. After the steel strip is cut, the first electric telescopic rod 173 is retracted, which drives the I-shaped plate 172 to move downward. The I-shaped plate 172 slides downward inside the rectangular hole 1321 through the rectangular bar 171. The rectangular bar 171 drives the extrusion wheel 17 to move closer to the first cylinder 1 until the extrusion wheel 17 is in close contact with the upper end of the rolled steel strip on the outside of the first cylinder 1. The extrusion wheel 17 is in close contact with the outside of the rolled steel strip. Then the first cylinder 1 is driven to rotate to roll up the last section of the cut steel strip to prevent the steel strip from loosening.

[0053] When the first cylinder 1 slides to one side in the middle of the fourth ring 131, it simultaneously drives the second cylinder 14 to slide in the middle of the fourth ring 131. The rolled steel strip on the outside of the first cylinder 1 can fall into the arc-shaped collection frame 18 through the gap between the first cylinder 1 and the second cylinder 14. The flexible material inside the arc-shaped collection frame 18 can be a sponge to hold the rolled steel strip that has been bumped.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
