When the movable member 60 is in the retracted position, the first guide slot 21 alone allows the rolled product to pass therethrough.
In actual production, when different production processes are adopted, the lengths of the guide and guards at the outlet of the rolling mill stand are different, so that the movable piece 60 is connected at the feed end 22 of the loop body 20, and the second guide groove 61 of the movable piece 60 can be overlapped with the first guide groove 21 in length to match the rolled piece to pass through. That is, when the movable member 60 is located at the extended position, the second guide grooves 61 of the movable member 60 correspond to and communicate with the first guide grooves 21 one by one, so that the lengths are overlapped, and the first guide grooves 21 and the second guide grooves 61 are used in cooperation for a rolled piece to pass through. When the movable member 60 is located at the retracted position, the first guide groove 21 and the second guide groove 61 are staggered from each other, and cannot be overlapped in length, so that the first guide groove 21 is used for the rolled piece to pass through alone. The looper 100 with the structure can be suitable for different guide lengths required by different processes, so that matching is performed through the movable piece 60, the universality of the looper 100 is further improved, and the number of online standby loopers 100 in a continuous rolling production line is reduced.
Further, as shown in fig. 4, the moveable member 60 is pivotally connected to the feed end 22 to effect movement of the moveable member 60 between the deployed and stowed positions. When the movable member 60 is turned to the unfolded position, the second guide grooves 61 of the movable member 60 correspond to and communicate with the first guide grooves 21 one by one, thereby performing length superposition. When the movable member 60 is turned to the retracted position, the movable member 60 covers the movable sleeve body 20. The movable member 60 is connected to the feed end 22 in a reversible manner to effect switching of the movable member 60 between the deployed and stowed positions, which is simple and easy to operate. In other embodiments, the moveable member 60 may have other configurations. For example, the moveable member 60 is movably coupled to the feed end 22 in a vertical direction to enable the moveable member 60 to be switched between the deployed position and the stowed position.
