For example, when the apparatus for coiling the slitter edge of the cold-rolled steel strip for manufacturing automobiles is used, the telescopic cylinder 31 drives the first roller 33 to abut against the second roller 43, the guide cylinder 51 drives the guide roller 52 to rotate, so that two steel strip slitter edges are guided into the transmission gap 525, the end parts of the two steel strip slitter edges are respectively fixed on the first roller 33 and the second roller 43, and then the rotary cylinder 41 drives the first roller 33 and the second roller 43 to rotate, so that the steel strip slitter edges are coiled on the first roller 33 and the second roller 43, and further the simultaneous coiling of the two steel strip slitter edges is realized, and the coiling efficiency is improved.

For example, in order to guide the steel scrap edge to be transferred from the transfer gap 525 to the first roller 33 and the second roller 43, the two mounting plates 13 are perpendicular to the bottom plate 11, the mounting frame 14 is mounted on the fixing frame 10, and opposite ends of the mounting frame 14 are respectively mounted on the two mounting plates 13. The opposite ends of the mounting bracket 14 are respectively provided with a vertical guide groove 141, and the opposite ends of the driven roller 53 are respectively provided with a guide rod 531 in a protruding manner. The guide rods 531 have a diameter smaller than that of the driven roller 53, and the two guide rods 531 are slidably inserted into the two upright guide grooves 141, respectively.

An included angle of 90-170 degrees is formed between the separating arm 335 and the supporting arm 435. The end surface of the separating arm 335 is convexly provided with a stopping convex part, and the stopping convex part is stopped on the inserting rod to limit the turning angle of the inserting rod relative to the separating arm 335. By forming an included angle of 90-170 degrees between the separating arm 335 and the supporting arm 435, the first winding area and the second winding area can be separated by using the separating arm 335 and the supporting arm 435, and the mutual winding of the two steel strip trims is avoided.

For example, it is particularly important that the separating arm 335 is perpendicular to the central axis of the first roller 33 with respect to the rotational axis of the first roller 33, and that the supporting arm 435 is perpendicular to the central axis of the second roller 43 with respect to the rotational axis of the second roller 43.

30 and 40, respectively. When the partition arm 335 and the support arm 435 are used to wind the strip edge, the roll-over stand 72 is under the action of external force to drive the follower roller 73 to rotate 90 degrees, so that the follower roller 73 is parallel to the bottom plate 11. Thereafter, the strip trim may be passed under the follower rollers 73 into the winding zone. For example, the adjustment cylinder 71 is used to drive the follower roller 73 upward to adjust the height of the follower roller 73.

The middle of the second arc-shaped flexible strip 754 is located below the abutting slot 142 and abuts against the top of the driven roller 53, two opposite ends of the second arc-shaped flexible strip 754 respectively extend upwards in an arc shape through the abutting slot 142, two opposite ends of the second arc-shaped flexible strip 754 are respectively connected to the middle of the two abutting strips 752, and two opposite ends of the first arc-shaped flexible strip 753 are respectively connected to two opposite ends of the second arc-shaped flexible strip 754. The middle of the first arc-shaped flexible strip 753 protrudes upward, and the middle of the second arc-shaped flexible strip 754 protrudes downward. For example, when the conveying gap 525 needs to be reduced, the pulling cylinder 74 pulls the hard rod 751 to descend, so that the two abutting strips 752 are rotated and spread in the direction away from each other, the first arc-shaped flexible strip 753 and the second arc-shaped flexible strip 754 are deformed under force and descend, so that the second arc-shaped flexible strip 754 abuts against the driven roller 53 to descend, and the size of the conveying gap is adjusted.
