Abstract
Description
Technical Field
[0001] The utility model relates to a steel coil bundling auxiliary device, belonging to the technical field of steel rolling production auxiliary equipment. Background Art
[0002] On the cold-rolled hot-dip galvanizing line, the steel coils taken off the line are transported to the bundling and lifting position by the walking beam. Before bundling is completed, the steel coils are left with a 300mm long tail to facilitate the connection between the steel coils off the line and the equipment. For strip steel with a thickness of more than 3.0mm, the strapping machine cannot completely tie the tail tightly against the steel coil when bundling, and there is still a certain opening between the tail and the steel coil, and the packaging material is easily damaged here during packaging. If the reserved length of the tail of the steel coil is shortened, the tail of the steel coil will enter between the saddles when the steel coil is placed on the saddle. During the process of moving the walking beam, the tail of the steel coil will be squeezed and deformed by the moving beam of the walking beam, making it impossible to bundle and package, and it needs to be cut off in a secondary process, resulting in a lower yield rate.

[0006] In the above-mentioned steel coil bundling auxiliary device, one end of the coupling is connected and matched with the output shaft key of the reducer, and the other end is connected and matched with the shaft key of the rotating roller; the rotating roller and the supporting roller are fixed on the static beam of the walking beam through the bearing seat.
[0007] The above-mentioned steel coil bundling auxiliary device comprises three support rollers and one rotating roller.

At this time, three supporting rollers and one rotating roller support the steel coil. Since the rotating roller has the same size as the supporting roller, the upper roller surfaces of the rotating roller and the supporting roller are on the same horizontal plane, ensuring that the steel coil is placed stably; operate the motor switch to turn The motor is driven, and the motor drives the reducer to rotate slowly, which drives the steel coil on the utility model to rotate slowly until the tail of the steel coil is pressed onto the roller surface of the supporting roller on the same side of the stepping beam and the static beam as the rotating roller, and stops rotating. At this time, the tail of the steel coil is at 7 o'clock below the steel coil side; then, the steel coil is moved to the static beam bundling position by the stepping beam moving beam, the stepping beam moving beam slowly descends, and the steel coil is stably placed on the saddle at the static beam bundling position, and the tail of the steel coil is pressed onto the V-shaped polyurethane pad of the static beam saddle, and the dead weight of the steel coil presses the tail tightly against the outer ring of the steel coil, and the baling machine is started to bundle the steel coil. When the strap is tightened, the tail of the strap can be tightly pressed against the outer ring, which is convenient for the packaging of the steel coil and reduces the damage of the packaging material.
[0009] The beneficial effects of the utility model are:
[0010] The utility model slowly rotates the steel coil by means of a rotating roller, adjusts the belt tail to the lower side of the steel coil, and assists a baling machine to tightly press the belt tail against the outer ring surface of the steel coil, thereby avoiding damage to the packaging material and improving the yield rate of the steel plate.

The utility model is installed at saddle position No. 1 on the walking beam static beam 6, saddle position No. 2 of the walking beam static beam is the steel coil bundling position, and saddle positions No. 3 and No. 4 are steel coil hoisting positions.
[0019] like Figure 1 As shown, the utility model is a steel coil bundling auxiliary device, comprising a motor 1, a reducer 2, a coupling 3, a rotating roller 4, three supporting rollers 5, two stepping beam static beams 6 and a stepping beam moving beam 7; the two stepping beam static beams 6 are distributed on both sides of the stepping beam moving beam 7; the roller diameters and lengths of the rotating roller 4 and the three supporting rollers 5 are the same; the bracket of the reducer 2 is fixed to the ground by bolts, the motor 1 is connected to the reducer 2 by bolts, the coupling 3 connects the reducer 2 and the rotating roller 4 concentrically, and the three supporting rollers 5 and the rotating roller 4 are fixed in pairs On the walking beam static beam 6 on both sides of the walking beam moving beam 7 and symmetrically in pairs along the walking beam moving beam 7; bearing seats are installed at both ends of the support roller 5 and the rotating roller 4, and the bearing seats are welded and installed on the steel plate of the walking beam static beam 6 to fix the support roller 5 and the rotating roller 4; after the utility model is installed, the axis of the rotating roller 4 and a supporting roller 5 symmetrical with it along the walking beam moving beam 7 coincide with each other, and the axes of the other two supporting rollers 5 symmetrical along the walking beam moving beam 7 coincide with each other; the axes of the rotating roller 4 and the three supporting rollers 5 are located on the same horizontal plane; the entire device plays a role in supporting the steel coil.
[0020] The steel coil 8 off the production line is placed on the cross saddle by the unloading trolley, the walking beam movable beam 7 moves the No. 1 saddle 9 of the walking beam movable beam 7 to the bottom of the cross saddle, the walking beam movable beam 7 rises to lift the steel coil 8 on the cross saddle, the walking beam movable beam 7 moves to move the steel coil 8 to the top of the utility model, the walking beam movable beam 7 slowly descends, and the steel coil 8 is placed on the utility model, and the steel coil 8 is at the No. 1 saddle position of the walking beam static beam 6; at this time, three supporting rollers 5 and one rotating roller 4 support the steel coil 8. Since the rotating roller 4 has the same size as the supporting roller 5, the upper roller surfaces of the rotating roller 4 and the supporting roller 5 are at the same horizontal plane, ensuring that the steel coil 8 is placed stably; Figure 2As shown, at this time, the opening between the tail 10 of the steel coil 8 and the steel coil is relatively large, which is not conducive to the subsequent bundling and packaging; the motor 1 is operated to turn the motor, and the motor 1 drives the reducer 2 to rotate slowly, driving the steel coil 8 on the utility model to rotate slowly until the tail 10 of the steel coil is pressed onto the roller surface of the support roller 5 on the same side of the stepping beam and the static beam 6 as the rotating roller 4, and the rotation stops. At this time, the tail 10 of the steel coil is at the 7 o'clock direction below the side of the steel coil 8, as shown in FIG. Figure 3 As shown; the walking beam movable beam 7 moves to the coil transfer position, the walking beam movable beam 7 rises to lift the steel coil 8 on the utility model, the walking beam movable beam 7 moves the steel coil 8 to the No. 2 saddle bundling position of the walking beam static beam 6, the walking beam movable beam 7 slowly descends, and the steel coil 8 is stably placed on the No. 2 saddle of the walking beam static beam 6, as shown Figure 5 As shown, the tail 10 of the steel coil 8 is pressed onto the polyurethane pad of the V-shaped saddle of the walking beam static beam 6.
