The initial position of the connecting rod 6 is located on the side of the connecting rod 6 that is away from the guide table 4 when the connecting rod 6 is perpendicular to the steel. When no external force is applied, the connecting rod 6 is vertically disposed downward. The connecting rod 6 and the abutment block 7 form a tensioning mechanism 9 for tensioning the steel material.

When the steel is loose, the connecting rod 6 rotates towards the vertical steel, so that the steel is tightly propped by the propping block 7 again, and the steel is smoothly transported forwards. When the steel receives large tension, the connecting rod 6 rotates towards the side far away from the guide table 4 under the action of the external force of the steel, so that the tension of the steel is reduced, and the possibility of deformation of the steel due to the fact that the steel receives too large tension is reduced.

As shown in fig. 4 and 5, the connecting rod 6 is positioned to slidably connect the rotating rollers 5 so that the maximum tension of the steel material by the tension mechanism 9 can be adjusted. Specifically, the side wall of the connecting rod 6 is provided with a through groove 10 along the length direction thereof. The rotating roller 5 is provided with a mounting bolt 11 in a penetrating way, and the mounting bolt 11 penetrates through the through groove 10. One end of the mounting bolt 11 is connected with a mounting nut 12 for tightly abutting against the rotating roller 5 through screw threads. When the maximum tension of the tensioning mechanism 9 on the steel needs to be adjusted, the mounting nut 12 is loosened, and then the connecting rod 6 slides relative to the rotating roller 5. When adjusted to the proper position, the mounting nut 12 is tightened and the connecting rod 6 and the rotating roller 5 are relatively fixed under the clamping force of the mounting bolt 11 and the mounting nut 12 against them. A fixed sliding connection of the connecting rod 6 with respect to the turning roller 5 is achieved.

As shown in fig. 6, in order that the abutting block 7 does not affect the installation of the new steel coil, one end of the rotating roller 5 is provided with an urging handle 13 along the radial direction thereof for facilitating the urging of the rotating roller 5 to rotate.

The rotating roller 5 is provided with a sliding groove 16 along the radial direction, and the connecting rod 6 is connected with the sliding groove 16 in a sliding manner. The connecting rod 6 is provided with a spring jumping bean 17 along the length direction thereof, and the inner wall of the sliding groove 16 is provided with a plurality of embedding holes 18 for embedding the spring jumping bean 17 along the length direction thereof. The spring jumping beans 17 are arranged in a plurality along the length direction of the connecting rod 6.

The embedding hole 18 has a limiting force on the spring jumping bean 17, so that the connecting rod 6 can be fixed relative to the rotating roller 5. The relative positions of the connecting rod 6 and the rotating roller 5 are adjusted by combining the spring jumping beans 17 in different embedding holes 18, so that the positioning sliding connection of the connecting rod 6 relative to the rotating roller 5 is realized. When the maximum tension of the tensioning mechanism 9 on steel needs to be adjusted, the connecting rod 6 only needs to slide relative to the rotating roller 5, and the spring jumping beans 17 are embedded into different embedding holes 18.
