[0002] Steel coil, also known as coiled steel. Steel is hot-pressed or cold-pressed into a coil, which is convenient for storage and transportation, and convenient for various processing (such as processing into steel plates, steel strips, etc.). In the production process of steel pipes, it is usually necessary to split the processed steel coil into strips, and then slit and roll the steel coil into several relatively narrow steel strips.

[0003] After a relatively wide steel coil is cut into several narrow steel strips, the strips usually need to be bundled. However, in the prior art, the narrow steel strips are usually wound first and then transported to the next process, where they are bundled by a bundling machine.

[0047] Reference Figure 3 and Figure 5When the steel strip is wound, the top plate 3121 is driven to move upward by the opening and closing cylinder 311, so that the top plate 3121 drives the top rod 3122 to move upward, so that the upper end of the top rod 3122 pushes the first connecting rod 3123 and the second connecting rod 3124 upward, so that the ends of the first connecting rod 3123 and the second connecting rod 3124 hinged to the top rod 3122 move upward, so that the other end of the first connecting rod 3123 pulls the right opening arm 313, so that the second connecting rod 3124 The other end of the left opening arm 314 is pulled, so that the right opening arm 313 and the left opening arm 314 are closed, so that the right mounting rod 315 and the left mounting rod 316 are closed, thereby driving the right binding member 321 and the left binding member 322 to surround the winding roller 231, so that the right positioning ring 331 and the left positioning ring 332 both contact the side wall of the wound steel strip roll, and are kept tightly against the steel strip roll under the action of the right positioning spring 333 and the left positioning spring 334, thereby reducing the disorder of the steel strip roll. While the opening and closing cylinder 311 drives the top plate 3121 to move upward, the top plate 3121 drives the linkage plate 317 to move upward, so that the linkage plate 317 drives the support plate 318 to move upward, thereby pushing the guide roller 233 upward, thereby causing the guide roller 233 to move away from the winding roller 231, so that when the right bundling piece 321 and the left bundling piece 322 surround the winding roller 231, the interference of the guide roller 233 with the right bundling piece 321 and the left bundling piece 322 is reduced.

[0048] Reference Figure 3 and Figure 6 When the linkage plate 317 pushes the support plate 318 to move upward, so that the support plate 318 drives the guide roller 233 to move upward, the slide bar 235 on the guide roller 233 drives the buffer plate 344 to move upward and compresses the buffer spring 345. When the buffer plate 344 moves upward until the avoidance block 341 is in the avoidance groove 3441 on the buffer plate 344, the avoidance block 341 rotates into the waist-shaped groove 11 under the action of the avoidance spring piece 342, so that the upper end of the avoidance block 341 extends outward into the waist-shaped groove 11, so that the avoidance block 341 is inserted into the avoidance groove 3441 of the buffer plate 344, thereby limiting the buffer plate 344.

[0049] Reference Figure 3 and Figure 5After the right binding piece 321 and the left binding piece 322 surround the steel strip roll on the winding roller 231, the steel strip roll is bound by the right binding piece 321 and the left binding piece 322. After the steel strip roll is bound, the opening and closing cylinder 311 drives the piston rod to retract, thereby driving the top plate 3121 to move downward, so that the top plate 3121 drives the top rod 3122 to move downward, so that the top rod 3122 pulls the first connecting rod 3123 and the second connecting rod 3124 downward, so that the angle between the first connecting rod 3123 and the second connecting rod 3124 gradually increases, so that the right opening arm 313 and the left opening arm 314 are stretched open by the first connecting rod 3123 and the second connecting rod 3124, so that the right opening arm 3121 is opened. The right and left opening arms 314 rotate away from the winding roller 231, thereby driving the right mounting rod 315 and the left mounting rod 316 to move away from the winding roller 231, thereby driving the right binding member 321 and the left binding member 322 to separate from the steel strip roll on the winding roller 231, thereby loosening the steel strip roll after binding, and then removing the winding roller 231 from the frame 1, so as to facilitate the unloading of the steel strip roll after binding. The unloading method of the steel strip roll is the existing technology in the field and will not be elaborated here. When the opening and closing cylinder 311 drives the top plate 3121 to descend, the top plate 3121 drives the linkage plate 317 to move downward. At this time, the buffer plate 344 remains stationary under the limit of the avoidance block 341, so that the guide roller 233 remains stationary at the current position, so that the support plate 318 stops moving, so that the support plate 318 moves relative to the linkage plate 317, and the guide rod slides in the linkage plate 317.

[0050] Reference Figure 5When the bundled steel strip coil is unloaded, the avoidance rod 343 is toggled to make the avoidance rod 343 drive the avoidance block 341 to rotate into the installation groove 12, so that the avoidance block 341 compresses the avoidance spring piece 342, and makes the avoidance block 341 gradually withdraw from the avoidance groove 3441, so that the avoidance block 341 is separated from the buffer plate 344, thereby releasing the limit of the buffer plate 344, so that the buffer plate 344 can move downward along the waist groove 11 under the action of the gravity of the guide roller 233, thereby driving the buffer plate 344 to descend, making the buffer plate 344 The part of the punch plate 344 provided with the avoidance groove 3441 moves downward, so that the avoidance groove 3441 is staggered with the avoidance block 341, and the guide roller 233 also drives the support plate 318 to move downward, so that the support plate 318 drives the guide rod to slide in the linkage plate 317, so that the support plate 318 gradually approaches the linkage plate 317, until the support plate 318 contacts the linkage plate 317, and thus remains stationary under the support of the linkage plate 317, at which time the guide roller 233 moves downward to the winding roller 231, so as to guide the subsequent winding steel strip. Then the avoidance rod 343 is released, so that the avoidance block 341 rotates toward the direction of the buffer plate 344 under the push of the avoidance spring 342, so that the avoidance block 341 contacts the side wall of the buffer plate 344, and at this time, the avoidance groove 3441 is located below the avoidance block 341.

[0051] The working principle of the embodiment of the present application is as follows: a whole roll of unstripped steel strip is conveyed to the unwinding roller 24, the steel strip is unwound by the unwinding roller 24, the unwound steel strip is conveyed to the cutting roller 211, the steel strip is cut and stripped by the slitting knife 212 on the cutting roller 211, so that the original complete steel strip is cut into a plurality of narrower steel strips, and the stripped steel strip is conveyed to the guide roller 233 by the conveying roller 221, so that the guide roller 233 guides the stripped steel strip to the winding roller 231 for winding, thereby winding it into a plurality of rolls of steel strip.

[0052] After the winding is completed, the opening component 31 is driven to move, so that the guide roller 233 moves away from the winding roller 231, and the opening component 31 drives the bundling component 32 to surround the steel strip on the winding roller 231 in the circumferential direction, and then the bundling component 32 is used to bundle the several rolls of steel strip on the winding roller 231. After the bundling is completed, the opening component 31 is driven to move again, so that the opening component 31 drives the bundling component 32 to separate from the steel strip roll on the winding roller 231, so as to facilitate the unloading of the bundled steel strip roll. At this time, the guide roller 233 is kept away from the winding roller 231 under the action of the avoidance component 34, thereby reducing the influence of the guide roller 233 on the unloading process of the bundled steel strip. After unloading is completed, the avoidance block 341 is driven to rotate through the avoidance rod 343, so that the avoidance block 341 is separated from the avoidance groove 3441, thereby releasing the limit on the guide roller 233, so that the guide roller 233 can be reset under the action of gravity, so as to guide the new steel strip to the winding roller 231.

[0053] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
