Description

Technical Field

[0001] The utility model relates to the technical field of metal strip coils, in particular to a bag turning and unloading machine for metal strip coils. Background Art

[0002] During the rolling production process of metal strips, each roll of metal strip material needs to be turned from a horizontal state to a vertical state.

[0003] During the rolling process, the finished metal coil is typically placed horizontally. However, for narrower coils, this can easily cause the coil to tip over, potentially damaging the product. Therefore, the coil must be turned over to position it vertically. An overhead crane is then used to hoist the vertically positioned coil onto the unwinder for unwinding and production.

[0004] However, in the process of transferring the metal coil from the bag turning machine to the unwinding machine using an overhead crane, friction is easily generated on the surface of the metal coil, which in turn causes defects such as roughness and scratches on the surface of the metal coil. Utility Model Content

For example, they can refer to fixed connections, detachable connections, or integral connections; of course, they can also refer to mechanical connections or electrical connections; in addition, they can also refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0024] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] Example

[0026] The specific implementation of the utility model is as follows Figure 1-2 As shown, a bag turning and unloading machine for metal strip coils includes a support base 1, which is a frame structure welded from channel steel or angle steel. A rotating seat 2 that can rotate downward 90 degrees is provided on the top of the support base 1. A discharge spindle 4 is horizontally provided on the top of the rotating seat 2, one end of which extends to the outside of the rotating seat 2 and can rotate axially. The extension direction of the discharge spindle 4 is perpendicular to the rotation axis of the rotating seat 2, and an outer baffle 6 with a vertically arranged plate surface is detachably mounted on the discharge spindle 4 located on the outside of the rotating seat 2. An inner baffle 5 parallel to the outer baffle 6 is also fixed to the discharge spindle 4 between the outer baffle 6 and the rotating seat 2.

[0027] Before use, first remove the outer baffle 6 from the unloading spindle 4, then put the metal strip roll on the unloading spindle 4 on the side of the inner baffle 5 facing away from the rotating seat 2, and then reinstall the outer baffle 6 on the unloading spindle 4 to achieve the installation of the metal strip roll before use.

[0028] To use this device, first rotate the rotating base 2 90°, so that the metal coil attached to the unwinding spindle 4 changes from a horizontal axis to a vertical axis, completing the metal coil turnover. Subsequently, during unwinding and production, the metal coil is supported by the inner baffle 5, which is fixed to the axially rotatable unwinding spindle 4. Therefore, the metal coil can rotate axially along with the inner baffle 5 and unwinding spindle 4 under the traction of the subsequent processing line, thereby enabling the unwinding of the metal coil.

[0029] Therefore, this equipment can realize the turnover and unloading of metal strip coils without the need for an overhead crane to transfer the metal strip coils between the turnover machine and the unloading machine. This also avoids the friction caused by the transfer process on the metal strip surface, thus preventing defects such as roughness and scratches on the metal strip surface, thereby ensuring the smoothness of the metal strip surface and the quality of subsequent products.

[0030] In order to achieve a 90° downward rotation of the rotating seat 2, the device has a side plate 22 vertically provided on the edge of the rotating seat 2 on the side close to the inner baffle 5. The discharge spindle 4 is arranged through the side plate 22, and there is a clearance fit between the discharge spindle 4 and the side plate 22. A bag turning cylinder 3 is provided on the side of the side plate 22 away from the inner baffle 5. The output end of the bag turning cylinder 3 is hinged to the side plate 22, and the fixed end is hinged to the bracket base 1. The telescopic drive of the bag turning cylinder 3 can provide a rotational driving force to the rotating seat 2. In this embodiment, in order to achieve the rotational installation of the rotating seat 2 on the bracket base 1, a rotating bearing seat 11 for rotating the rotating seat 2 is provided at the top of the bracket base 1, and a mounting shaft 21 that rotates with the rotating bearing seat 11 is provided at the bottom of the rotating seat 2.

[0031] To mount the unloading spindle 4, the top of the rotating base 2 is equipped with at least two spindle bearing blocks 23 for rotatably mounting the unloading spindle 4. In this embodiment, the unloading spindle 4 passes through the two spindle bearing blocks 23 in sequence, achieving axial mounting of the unloading spindle 4. Furthermore, to stop the rotation of the unloading spindle 4 when necessary, a spindle brake 24 is also installed on the top of the rotating base 2. The spindle brake 24 is known from the prior art, and its specific structure will not be described in detail here.

[0032] In addition, in order to achieve detachable installation of the outer baffle 6, an internal threaded sleeve 61 for detachably installing it on the discharge spindle 4 is provided at the axis center of the outer baffle 6, and an external thread that matches the internal threaded sleeve 61 is provided on the outer wall of the discharge spindle 4.

[0033] In addition, the inner baffle 5 is fixedly provided with a plurality of limiting bars 51 on the side of the plate near the outer baffle 6. The limiting bars 51 extend radially along the cross-section of the unwinding spindle 4. In this embodiment, the limiting bars 51 are arranged rotationally symmetrically around the unwinding spindle 4. The limiting bars 51 fully support the metal coil during unwinding.

[0034] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
