Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to a device for unwinding multiple aluminum strips. Background Art

[0002] When aluminum strips are purchased and sent back to the factory, they are in the form of aluminum coils. In the subsequent processing of the workshop, the aluminum coils must be mounted on the unwinding machine, and one end of the aluminum strip must be connected to the traction equipment. Under the traction of the traction equipment on the aluminum strip, the aluminum coils follow the rotation to achieve the purpose of unwinding and unloading.

[0003] The existing aluminum strip unwinding machines unwind a single aluminum coil when unwinding. However, in this way, one unwinding machine can only supply one forming device in front, and cannot complete the purpose of unwinding and feeding multiple devices at the same time. Therefore, this unwinding method is inefficient and has a great impact on the subsequent product processing efficiency.

[0004] Therefore, there is an urgent need for a multiple aluminum strip unwinding device that can unwind and unwind multiple aluminum coils at the same time to improve the efficiency of unwinding and processing. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a multiple aluminum strip unwinding device, which is used to solve the problem that the existing aluminum strip unwinding machine cannot unwind and discharge multiple aluminum coils at the same time, thereby resulting in low discharge and processing efficiency.

[0011] Furthermore, a plurality of supporting legs are provided on the other side of the supporting beam, the supporting legs are coplanar with the supporting beam, and the other ends of the supporting legs are fixed to the base frame.

[0012] Furthermore, the distance between the mounting opening and the base frame is greater than the diameter of the aluminum coil.

[0013] Furthermore, the tensioning mechanism includes a rotating sleeve, which cooperates with the second rotating shaft, and a plurality of first threaded sleeves are provided in a circular array on the rotating sleeve, a screw rod is provided inside the first threaded sleeve, and a second threaded sleeve is provided at the other end of the screw rod, the threads in the first threaded sleeve and the second threaded sleeve have opposite directions, and a tensioning plate is provided at the other end of the second threaded sleeve.

[0014] Furthermore, two end plates are provided in parallel at both ends of the rotating sleeve, and the distance between the two end plates is not greater than the distance between two adjacent support beams.

DETAILED DESCRIPTION

[0031] The present invention will be described clearly and completely below in conjunction with the embodiments.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] See attached Figure 1-2, shown is a multiple aluminum strip unwinding device, including a base frame 1, an unwinding frame and a tensioning mechanism 10 arranged on the unwinding frame. Specifically, the base frame 1 is welded and fixed with an unwinding frame, wherein the unwinding frame includes a plurality of E-shaped frames 2 arranged in parallel and at equal intervals, and the spacing between two adjacent E-shaped frames 2 is greater than the thickness of the aluminum coil 20. The E-shaped frame 2 is provided with a support beam 3, and support legs 4 are provided at both ends and the middle of one side of the support beam 3. The support legs 4 are equal in thickness to the support beam 3 and are arranged in the same plane. In this way, the width of the two adjacent E-shaped frames 2 can be kept at the maximum to avoid contact with the aluminum coil. 20 interference occurs, a plurality of mounting openings 5 ​​are opened on the support beam 3, the mounting openings 5 ​​on two adjacent support beams 3 are of equal diameter and concentric, and the spacing between two adjacent mounting openings 5 ​​increases successively from the left end of the support beam 3. When in use, the mounting openings 5 ​​with larger spacing can be used to mount and unwind the large-diameter aluminum coil 20. When the large-diameter aluminum coil 20 is unwound to become a small-diameter aluminum coil 20, the small-diameter aluminum coil 20 can be mounted in the mounting openings 5 ​​with smaller spacing, and the large-diameter aluminum coil 20 can continue to be placed in the mounting openings 5 ​​with larger spacing as a backup;

[0035] In addition, a rotating support device 6 is installed in two concentric installation openings 5 ​​on two adjacent support beams 3. The rotating support device 6 is arranged on the entire unwinding frame through the installation opening 5 according to an N-shaped path. At the same time, a tensioning mechanism 10 for tensioning the aluminum coil 20 is provided on the rotating support device 6. By arranging the rotating support device 6 according to the N-shaped path, the tensioning mechanism 10 can realize the installation and unwinding of multiple aluminum coils 20 at the same time, and the aluminum coils 20 do not interfere with each other. Therefore, compared with the original unwinding machine, the number of aluminum coils 20 installed is increased, the efficiency of unwinding is improved, and multiple equipment can be supplied for processing at the same time, which indirectly improves the processing efficiency;

[0036] See attached Figure 3 , the rotating support device 6 shown is provided with a first rotating shaft 7, and bearings 9 are provided at both ends of the first rotating shaft 7. The bearings 9 are located in the mounting opening 5. The friction between the first rotating shaft 7 and the mounting opening 5 can be reduced by the bearings 9, thereby reducing the wear of the first rotating shaft 7. The first rotating shaft 7 is provided with a second rotating shaft 8 between the two bearings 9. The cross section of the second rotating shaft 8 is polygonal. The second rotating shaft 8 is provided with a tensioning mechanism 10. The second rotating shaft 8 can prevent slipping when cooperating with the tensioning mechanism 10 through the polygonal cross-sectional structure. In this way, the rotation of the entire aluminum coil 20 and the tensioning mechanism 10 can be concentrated through the bearings 9, thereby improving the stability of the material discharge and reducing the wear of the second rotating shaft 8;

[0037] See attached Figure 4-5As shown, the tensioning mechanism 10 includes a rotating sleeve 11, which cooperates with the second rotating shaft 8. Four first threaded sleeves 12 are arranged in a circumferential array on the outer wall of the rotating sleeve 11. A screw 14 is arranged in the first threaded sleeve 12. The other end of the screw 14 is arranged in a second threaded sleeve 13. The thread directions of the first threaded sleeve 12 and the second threaded sleeve 13 are opposite. The other end of the second threaded sleeve 13 is connected to a tensioning plate 16 with an arc structure. When in use, the entire tensioning mechanism 10 is first placed in the inner hole of the aluminum coil 20, and then the screw 14 is rotated to make the first threaded sleeve 12 and the second threaded sleeve 13 move toward each other so that the tensioning plate 16 is attached to the inner hole wall of the aluminum coil 20 to achieve tensioning. When unloading, the tensioning mechanism rotates with the aluminum coil 20;

[0038] In addition, in order to rotate the screw rod 14 more conveniently and labor-savingly, a rotating member 15 is provided in the middle of the screw rod 14, and force can be conveniently applied to the screw rod 14 through the rotating member 15;

[0039] In addition, the second rotating shaft 8 is located on both sides of the rotating sleeve 11 and is provided with end plates 17. The maximum spacing between the two end plates 17 is smaller than the spacing between the inner walls of the two adjacent support beams 3. The end plates 17 can limit the rotating sleeve 11, thereby reducing the large-range left and right movement of the rotating sleeve 11 on the second rotating shaft 8 when the tensioning mechanism 10 rotates, thereby reducing the stability of the unwinding of the aluminum coil 20.

[0040] See also Appendix Figure 5 As shown, in order to improve the stability of the tensioning plate 16 and prevent the screw 14 from moving with the rotation, a guide sleeve 18 is provided perpendicular to the axial direction of the first threaded sleeve 12. The four guide sleeves 18 are connected end to end. A guide rod 19 is provided in the guide sleeve 18, and the other end of the guide rod 19 is connected to the tensioning plate 16.

[0041] See attached Figure 6 When in use, firstly, the rotating member 15 drives the screw rod 14 to rotate and adjust the four tensioning plates 16 to shrink inward so that the diameter of the entire tensioning mechanism 10 is smaller than the inner diameter of the aluminum coil 20, and then the tensioning mechanism 10 is placed in the inner hole of the aluminum coil 20, and then the screw rod 14 is reversed again to drive the tensioning plate 16 to expand outward and make the tensioning plate 16 fit to the inner hole wall of the aluminum coil 20, and then the rotation support device 6 is installed in the rotating sleeve 11, and then the aluminum coil 20 installed with the tensioning mechanism 10 and the rotation support device 6 is sequentially erected in the erection opening 5 of the support beam 3 according to the N-shaped arrangement path, and then one end of the aluminum strip is placed in the traction device at the front end, and the aluminum coil 20 is pulled along the first rotating shaft 7 to rotate under the drive of the traction device to realize material discharge.

[0042] The above description is only a preferred specific implementation method of the present utility model, and does not limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
