[0024] First embodiment:

[0025] This embodiment discloses an aluminum coil unwinding machine.

[0026] The aluminum coil unwinding machine includes a base 1, a housing 2, and a rotating assembly 3.

[0027] like Figure 1 As shown, base 1 is placed on the ground. The housing 2 is rotatably mounted on top of base 1. For example, a first motor (not shown) is installed inside base 1. The aluminum coil unwinding machine also includes a first rotating shaft 11, with its upper end fixedly connected to housing 2 and its lower end rotatably connected to base 1. The output end of the first motor is connected to the lower end of the first rotating shaft 11. The first motor drives the first rotating shaft 11 to rotate, and the first rotating shaft 11 drives housing 2 to rotate 180°, thereby enabling the rotating components 3 on both sides to alternately unwind.

[0028] like Figure 1 and Figure 2 As shown, there are two rotating components 3. The rotating component 3 includes a disc body 31, an arc plate 33, and a limiting frame 34.

[0029] The disc body 31 is rotatably mounted on both sides of the housing 2. Exemplarily, the rotating assembly 3 includes a second rotating shaft 32 and a second motor (not shown). The second rotating shaft 32 is rotatably mounted on both sides of the housing 2, and the disc body 31 is fixedly mounted on the outside of the second rotating shaft 32. Two second motors are staggered within the housing 2, and the output ends of the two second motors are connected to the second rotating shaft 32. The second motors drive the second rotating shaft 32 to rotate, which in turn drives the disc body 31 to rotate, thereby unwinding the corresponding roll material.

[0030] The arc plate 33 is arc-shaped and is circumferentially spaced on the side of the disk body 31 away from the chassis 2. There are five limiting brackets 34, four of which have their first end fitted onto the outer side of the arc plate 33 near the chassis 2 and connected to the arc plate 33 with screws 345, and their second end extending towards the end away from the axis of the disk body 31. The remaining limiting bracket 34 has its first end fitted onto the outer side of the arc plate 33 away from the chassis 2 and connected to the arc plate 33 with screws 345, and its second end extending towards the end away from the axis of the disk body 31. Exemplarily, the limiting bracket 34 includes a first rod 341, a second rod 342, a crossbar 343, and a hook 344. The first rod 341 and the second rod 342 are radially symmetrically arranged with respect to the disk body 31, and the second end of the first rod 341 is connected to the second end of the second rod 342 in a conical shape. The crossbar 343 connects the first end of the first rod 341 and the first end of the second rod 342. Two hooks 344 are provided, respectively connected to the first end of the first rod 341 and the first end of the second rod 342. The two hooks 344 and the crossbar 343 form a through hole for the arc plate 33 to pass through. The crossbar 343 is connected to the arc plate 33 by screws 345. The limiting bracket 34 has a strong axial force bearing capacity and is easy to assemble and disassemble. Specifically, there are four arc plates 33, evenly spaced circumferentially, all on the same circle. The circle containing the four arc plates 33 is concentric with the disk body 31.

[0031] In this embodiment, a disc body 31 is rotatably arranged on both sides of the housing 2. An arc plate 33 is arranged circumferentially at the end of the disc body 31 away from the housing 2. A limiting frame 34 is fitted on the outer side of the arc plate 33 near the housing 2 and on the outer side of the arc plate 33 away from the housing 2. At the same time, the limiting frame 34 is connected to the arc plate 33 by screws 345, which facilitates the installation and removal of the limiting frame 34. After the coil is fitted on the outer side of the arc plate 33, the limiting frame 34 at the end away from the housing 2 and the limiting frame 34 at the end near the housing 2 restrict the axial movement of the coil, thereby improving the stability of the coil during use.

[0032] Second embodiment:

[0033] Based on the first embodiment, the second embodiment further optimizes and refines the aluminum coil unwinding machine.

[0034] like Figure 3 As shown, the arc plate 33 slides radially relative to the disc body 31. The aluminum coil unwinding machine also includes an adjusting assembly 4, which includes a sleeve 41, a screw 42, a pressure plate 43, and a swing arm 44. The sleeve 41 is slidably fitted onto the outside of the second rotating shaft 32. The screw 42 is threadedly connected to the end of the second rotating shaft 32 away from the housing 2. The pressure plate 43 is located on the outside of the screw 42 away from the housing 2, and the end of the pressure plate 43 near the housing 2 abuts against the sleeve 41. There are two sets of swing arms 44, which are arranged in parallel. The first end is rotatably connected to the outside of the sleeve 41, and the second end is rotatably connected to the inside of the arc plate 33.

[0035] For example, a first connecting plate 331 is radially arranged on the inner side of the arc plate 33, and a second connecting plate 411 is radially arranged on the outer side of the sleeve 41. Each set of swing arms 44 has two arms, which are symmetrically arranged on both sides of the first connecting plate 331 and the second connecting plate 411. A sliding groove 311 is radially formed on the disc body 31, through which the first connecting plate 331 passes, and the sliding groove 311 limits the sliding distance of the first connecting plate 331. The arc plate 33 includes a first roller 3311 and a second roller 3312. There are two sets of first rollers 3311, which are rotatably arranged on both sides of the first connecting plate 331 and roll on the side of the disc body 31 closest to the chassis 2. There is one set of second rollers 3312, which are rotatably arranged on both sides of the first connecting plate 331 and roll on the side of the disc body 31 away from the chassis 2. The first rollers 3311 and the second rollers 3312 cooperate to clamp the disc body 31, so that the first connecting plate 331 remains stable when sliding.

[0036] In this embodiment, by rotating the screw 42, the screw 42 generates a threaded displacement relative to the second rotating shaft 32, moving closer to or away from the second rotating shaft 32. The sleeve 41 slides along the pressure plate 43 on the screw 42, moving closer to or away from the second rotating shaft 32. The sleeve 41 drives the rocker arm to rotate, and the rocker arm drives the arc plate 33 to slide along the radial direction of the disc 31, moving closer to or away from the axis of the disc 31, so as to adjust the outer diameter of the arc plate 33, thereby adapting to coils with different inner diameters.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
