Description

Technical Field

[0001] This utility model relates to the field of aluminum coil winding technology, and more specifically, to a coil changing device for aluminum coil winding. Background Technology

[0002] Aluminum coils are metal products produced by rolling and bending on a casting and rolling mill, and are widely used in electronics, packaging, construction, machinery and other fields.

[0003] After searching, it was found that application number CN202323166772.6, entitled "Aluminum Coil Variable Diameter Sleeve," discloses prior art (publication number CN202461186U) of a top-cone type variable diameter sleeve. However, this sleeve requires workers to disassemble the bearing end cap from the winding shaft after the aluminum coil is wound up before the coil and core can be removed together. This installation and disassembly process is cumbersome, time-consuming, and labor-intensive, causing inconvenience for core replacement and affecting the coil winding efficiency. While the application improves the convenience of replacement by incorporating a movable frame, winding shaft, variable diameter top cone, and sleeve plate, it still requires workers to use equipment for disassembly. Due to the large weight of the aluminum coil, lifting equipment is needed, and the installation and disassembly of the aluminum coil clamps are cumbersome. Reinstalling the sleeve requires lifting it to a fixed position, which is also inconvenient. Further improvements are needed.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0029] According to an embodiment of the present invention, a rewinding device for aluminum coils is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, an aluminum coil winding and changing device according to an embodiment of the present invention includes a movable base 1 and a top frame 2. The top surface of the movable base 1 is hinged to the top frame 2 via a first hinge seat 9, and a drive motor 3 is fixedly installed on the top surface of the top frame 2. A lead screw 4 is installed at the output end of the drive motor 3. The top of the lead screw 4 is rotatably connected to the top frame 2 via a bearing, and the bottom surface of the lead screw 4 is rotatably connected to the inner bottom surface of the top frame 2 via a rotary connecting seat 8. A lifting seat 5 is slidably connected to the inner side of the top frame 2, and one side surface of the lifting seat 5... A hook 6 is fixedly installed. A lead screw 4 passes through and is threadedly connected to the lifting seat 5. A hydraulic cylinder 14 is hinged to one end of the top surface of the movable base 1 via a third hinge seat 15. The other end of the piston rod of the hydraulic cylinder 14 is hinged to a slider 12 via a second hinge seat 13. An end plate 10 is fixedly connected to the back facade of the top frame 2. A sliding rod 11 is fixedly installed between the end plates 10, and the sliding rod 11 passes through and is slidably connected to the slider 12. When changing the aluminum coil, the operator can push the device until the hook 6 is below the aluminum coil. Then, the drive motor 3 is started, driving the lead screw 4 to rotate, which in turn moves the lifting seat 5 upward, causing the hook 6 to hook onto both ends of the aluminum coil. Subsequently, after releasing the winding machine from fixing the center winding drum of the aluminum coil, the operator can push this device to move the aluminum coil to the storage position. Then, the new aluminum coil winding drum is placed inside the hook 6. The bottom of the hook 6 has an arc-shaped structure, so the aluminum coil winding drum is naturally located at the bottom inside the hook 6. By raising and lowering the hook 6, the winding drum can be moved to the fixed position of the winding machine, and the new winding drum is fixed, completing the entire replacement process. This eliminates the trouble of using hoisting equipment and improves the work efficiency of aluminum coil replacement. At the same time, after the aluminum coil is transferred to the storage position, the operator can activate the hydraulic cylinder 14 to extend, pushing the top frame 2 to tilt to the side, which in turn causes the hook 6 to tilt to the side. After the hook 6 tilts to a certain extent, the aluminum coil can roll away from the hook 6, completing automatic unloading, which improves the convenience of unloading and thus the ease of use. Compared with traditional hoisting equipment, there is no need for operators to disassemble and install or remove clamps, further improving the ease of use.

[0031] In one embodiment, a movable wheel 16 is fixedly installed at the corner of the bottom surface of the movable base 1, and the movable wheel 16 is a load-bearing universal wheel, which facilitates movement and turning.

[0032] In one embodiment, hooks 6 are distributed at both ends of the lifting base 5, and hooks 6 are made of metal structure that is not easily deformed, which is convenient for bearing the weight of aluminum coils.

[0033] In one embodiment, a guide rod 7 is vertically fixedly installed inside the top frame 2, and the guide rod 7 passes through the lifting seat 5 and is slidably connected to the lifting seat 5. Multiple sets of guide rods 7 are arranged, and the guide rods 7 guide the lifting of the lifting seat 5, thereby improving the stability of the lifting of the lifting seat 5.

[0034] In one embodiment, multiple sets of first hinge seats 9 are arranged, and the first hinge seats 9 are distributed at both ends of the bottom frame to improve the stability of the hinge.

[0035] In one embodiment, the bottom of the hook 6 has a semi-circular structure, and a stabilizing frame is welded between the hook 6 and the lifting seat 5 to improve stability.

[0036] In one embodiment, the slide bar 11 is a smooth metal round bar, which facilitates the sliding of the slider 12.

[0037] Working principle:

[0038] When changing the aluminum coil drum, the operator can push this device until hook 6 is below the aluminum coil. Then, start the drive motor 3 to rotate the lead screw 4, which moves the lifting seat 5 upward, causing hook 6 to hook onto both ends of the aluminum coil. After releasing the winding machine from fixing the center winding drum of the aluminum coil, the operator can push this device to move the aluminum coil to the storage position. Then, place the new aluminum coil winding drum inside hook 6. The bottom of hook 6 has an arc-shaped structure, so the aluminum coil winding drum naturally sits at the bottom of hook 6. By raising and lowering hook 6, the winding drum can be moved to the fixed position of the winding machine. The new winding drum is fixed in place, completing the entire replacement process. This eliminates the hassle of using hoisting equipment and improves the efficiency of aluminum coil replacement. Simultaneously, after the aluminum coil is transferred to the storage location, the operator can activate the hydraulic cylinder 14 to extend, pushing the top frame 2 to tilt, which in turn causes the hook 6 to tilt. Once the hook 6 tilts to a certain extent, the aluminum coil rolls off the hook 6, completing automatic unloading. This improves the convenience of unloading and, consequently, the ease of use. Compared to traditional hoisting equipment, there is no need for operators to disassemble or remove clamps, further enhancing usability.
