Description

Technical Field

[0001] This utility model relates to the technical field of aluminum processing, and in particular to an aluminum plate coiling tool. Background Technology

[0002] As a type of metal processing equipment, aluminum sheet coiling machines are closely related to the processing needs of sheet metal. With the widespread application of aluminum sheets in aerospace, automotive manufacturing, and building materials industries, the market demand for aluminum sheet coiling machines continues to grow. Especially in the construction industry, the application of aluminum sheet coiling machines is becoming increasingly widespread, providing huge development potential for the market.

[0003] Existing technologies suffer from several problems. During the aluminum sheet winding process, the inability to firmly press the left and right edges causes the sheet to wobble, resulting in unevenly rolled sheets that are unsuitable for subsequent storage and transportation. Without lateral restraints during the rolling process, this problem is exacerbated. Furthermore, aluminum sheets come in various widths, requiring different tooling changes to accommodate different specifications, which is time-consuming, labor-intensive, and impacts production efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This utility model provides an aluminum plate coiling fixture, which aims to solve the problem of edge wobbling caused by the inability to effectively press the left and right edges together, as well as the problem of needing to change fixtures during the coiling process of aluminum plates of different widths.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model proposes an aluminum sheet winding fixture, comprising a first frame, a roller, a limiting plate, and a roller bearing assembly. The roller is rotatably mounted on the first frame for winding the aluminum sheet. The limiting plate is slidably mounted on the roller and connected to the first frame via an elastic element. The limiting plate can slide left and right along the axial direction of the roller to clamp the aluminum sheet roll between the two limiting plates. The roller bearing assembly is correspondingly arranged to the roller and is used to press the aluminum sheet roll radially. The length of the roller bearing assembly can be adjusted according to the width of aluminum sheets of different specifications.

[0008] A further technical solution is that a groove is formed on the roller, and a slider that cooperates with the groove is provided on the limiting plate, so that the limiting plate can move back and forth along the groove by means of the slider.

[0009] A further technical solution involves providing a fixing structure on the roller shaft for fixing the aluminum sheet at the start of the aluminum sheet winding process. The fixing structure includes an elongated groove along the axial direction of the roller shaft and a fixing rod arranged along the axial direction of the elongated groove. The fixing rod has a square cross-section, and one end of the aluminum sheet is wound around the fixing rod and located in the gap between the fixing rod and the elongated groove.

[0010] A further technical solution includes a second frame, wherein the roller bearing assembly is movably connected to the second frame and located above the roller.

[0011] A further technical solution involves the roller bearing assembly comprising a first roller bearing, a second roller bearing, a support frame, and an adjusting handwheel. Both the first and second roller bearings are slidably disposed within the support frame and are positioned opposite each other. The first roller bearing has a first rack on the side near the second roller bearing, and the second roller bearing has a second rack on the side near the first roller bearing; the first and second racks are connected by a gear transmission. The adjusting handwheel is connected to the gears via a connecting rod, enabling the gears to rotate, thereby allowing the first and second roller bearings to slide relative to each other or away, thus adjusting the length of the roller bearing assembly to match the width of the aluminum plate.

[0012] A further technical solution is that slip rings are provided at both ends of the support frame, the slip rings are movably sleeved on the connecting column extending downward from the second frame, and the upper part of the slip rings is connected to the second frame by a spring.

[0013] A further technical solution includes a drive device and a base. The first frame and the second frame are fixed to the base, and the roller bearing assembly is located directly above the roller. One end of the roller is driven by the drive device.

[0014] A further technical solution is that the drive device is driven by a belt, chain, or gear.

[0015] A further technical solution is that the driving device includes a drive motor fixed on the base and a drive wheel located at the output end of the drive motor. One end of the roller shaft is fixed with a driven wheel that is connected to the drive wheel in a transmission manner. The drive wheel and the driven wheel are connected by a belt.

[0016] (III) Beneficial Effects

[0017] In the aluminum sheet winding fixture described above, the first frame provides excellent support for the entire roller shaft, ensuring smooth rotation and thus stable winding of the aluminum sheet. The limiting plates can slide left and right along the roller shaft's axial direction, automatically adjusting the clamping force according to the diameter of the aluminum sheet roll. This ensures a tight clamping of the aluminum sheet roll between the two limiting plates, preventing loosening or shifting during winding. The roller bearing assembly is correspondingly positioned to the roller shaft and is used to press the left and right edges of the aluminum sheet roll radially. This enhances the stability of the aluminum sheet roll during winding, helps improve the winding quality, and prevents wrinkles or damage to the aluminum sheet edges. The length of the roller bearing assembly can be adjusted according to the width of aluminum sheets of different specifications. This adjustability allows the aluminum sheet winding fixture to be applied to aluminum sheets of different widths, improving the equipment's versatility and flexibility, and reducing production costs and equipment investment.

Detailed Implementation

[0023] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This embodiment provides an aluminum sheet coiling fixture, such as... Figure 1As shown, the assembly includes a first frame 1, a roller 2, a limiting plate 3, and a roller bearing assembly 4. The roller 2 is rotatably mounted on the first frame 1 and is used to wind up aluminum sheets. The limiting plate 3 is slidably mounted on the roller 2 and connected to the first frame 1 via an elastic element 5. The limiting plate 3 can slide left and right along the axial direction of the roller 2 so that the aluminum sheet roll can be clamped between the two limiting plates 3. The roller bearing assembly 4 is correspondingly arranged with the roller 2 and is used to press the left and right edges of the aluminum sheet roll from the radial direction. The length of the roller bearing assembly 4 can be adjusted according to the width of aluminum sheets of different specifications.

[0025] In the aluminum sheet winding fixture described above, the first frame 1 provides excellent support for the entire roller 2, ensuring smooth rotation of the roller 2 and thus achieving stable winding of the aluminum sheet. Bearings can also be installed at the connection between the roller 2 and the first frame 1 to help reduce friction during roller 2 rotation. A limiting plate 3 is slidably mounted on the roller 2 and connected to the first frame 1 via an elastic element 5. This allows the limiting plate 3 to slide left and right along the axial direction of the roller 2, automatically adjusting the clamping force according to the diameter of the aluminum sheet roll, ensuring a tight clamping of the aluminum sheet roll between the two limiting plates 3, preventing loosening or displacement of the aluminum sheet roll during winding. A roller bearing assembly 4 is correspondingly positioned to the roller 2 and is used to press the left and right edges of the aluminum sheet roll from the radial direction. This enhances the stability of the aluminum sheet roll during winding, helps improve the winding quality of the aluminum sheet roll, and avoids wrinkles or damage to the aluminum sheet edges. The length of the roller bearing assembly 4 can be adjusted according to the width of aluminum sheets of different specifications. This adjustability allows the aluminum sheet winding fixture to be adapted to aluminum sheets of different widths, improving the versatility and flexibility of the equipment and reducing production costs and equipment investment.

[0026] Reference Figure 2 As shown, in this embodiment, a groove 21 is provided on the roller 2, and a slider 31 that cooperates with the groove 21 is provided on the limiting plate 3. The limiting plate 3 can move back and forth along the groove 21 by the slider 31.

[0027] The groove 21 provides a stable guide for the movement of the limiting plate 3 on the roller 2, ensuring that the limiting plate 3 does not rotate or wobble during movement, and effectively maintaining the neatness of the aluminum coil edge. Specifically, in this embodiment, the limiting plate is annular. The annular shape can well adapt to the shape of the aluminum coil. The slider is square, and the matching groove is also square. The slider and the limiting plate are connected by bolts.

[0028] In this embodiment, the roller 2 is provided with a fixing structure 22 for fixing the aluminum plate at the start of the aluminum plate winding. Specifically, the fixing structure 22 includes an elongated groove 221 opened along the axial direction of the roller 2 and a fixing rod 222 arranged along the axial direction of the elongated groove 221. The fixing rod 222 has a square cross-section. One end of the aluminum plate is wrapped around the fixing rod 222 and located in the gap between the fixing rod 222 and the elongated groove 221. It should be noted that the gap between the fixing rod 222 and the elongated groove 221 needs to be relatively thick for the aluminum plate. One end of the aluminum plate passes through the gap and wraps around the fixing rod 222, thereby fixing one end of the aluminum plate.

[0029] The fixing structure 22 secures the aluminum sheet at the start of winding, preventing it from shifting or slipping during the initial winding stage. This ensures the stability and continuity of the winding process. By fixing the aluminum sheet with the fixing structure 22, it is ensured that the aluminum sheet maintains the correct position and angle throughout the winding process. This helps improve winding accuracy and overall product quality.

[0030] Reference Figure 3 As shown, this embodiment also includes a second frame 6, with the roller bearing assembly 4 movably connected to the second frame 6 and located above the roller 2. Specifically, the roller bearing assembly 4 includes a first roller bearing 41, a second roller bearing 42, a support frame 43, and an adjusting handwheel 44. The first roller bearing 41 and the second roller bearing 42 are both slidably disposed inside the support frame 43 and are arranged opposite to each other. The first roller bearing 41 has a first rack on the side near the second roller bearing 42, and the second roller bearing 42 has a second rack on the side near the second roller 2. The first rack and the second rack are connected by a gear transmission. The adjusting handwheel 44 is connected to the gear through a connecting rod, which can drive the gear to rotate, thereby causing the first roller bearing 41 and the second roller bearing 42 to slide relative to each other, so as to adjust the length of the roller bearing assembly 4 to match the width of the aluminum plate.

[0031] The roller bearing assembly 4 can be adjusted in length to accommodate aluminum sheets of different widths. By adjusting the handwheel 44 to drive the gear rotation, the first roller bearing 41 and the second roller bearing 42 slide closer or further apart, allowing the tooling to flexibly handle aluminum sheets of various specifications, greatly improving its versatility and adaptability. The first roller bearing 41 and the second roller bearing 42 are connected by gear transmission, ensuring synchronization and stability during sliding. This helps maintain the stability of the roller bearing assembly 4 during aluminum sheet winding, thereby improving winding quality and safety. Adjusting the handwheel 44 allows the operator to easily adjust the length of the roller bearing assembly 4. By adjusting the relative position between the first roller bearing 41 and the second roller bearing 42, precise pressing of the aluminum sheet edges can be achieved. This helps optimize pressure distribution during winding, reducing wrinkles and damage to the aluminum sheet edges. The operator can quickly adjust the length of the roller bearing assembly 4 according to the width of the aluminum sheet, thereby reducing changeover time and improving production efficiency.

[0032] Specifically, in this embodiment, the support frame 43 is provided with slip rings 431 at both ends. The slip rings 431 are movably sleeved on the connecting post 61 extending downward from the second frame 6. The upper part of the slip rings 431 is connected to the second frame 6 via a spring 9. It should be noted that the length of the connecting post 61 is set to ensure that when the roller bearing assembly 4 is at its lowest point, it is close to the roller 2, so as to ensure that pressure can be applied to the aluminum plate when winding begins.

[0033] The slip ring 431 and the connecting post 61 are in a sliding connection. The slip ring 431 can slide on the connecting post 61 to drive the entire roller bearing assembly 4 to move radially along the aluminum plate coil. The first roller bearing 41 and the second roller bearing 42 are kept pressed against the two ends of the aluminum plate coil during the winding process under the pressure of the spring 9, which plays a role in adaptive adjustment according to the number of aluminum plate layers in the aluminum plate coil.

[0034] like Figure 1 As shown in the diagram, this embodiment also includes a drive device 7 and a base 8. The first frame 1 and the second frame 6 are fixed to the base 8, and it is necessary to ensure that the roller bearing assembly 4 on the second frame 6 is directly above the roller 2 on the first frame 1. One end of the roller 2 is connected to the drive device 7. In this embodiment, the drive device 7 is driven by a belt, but chain drive or gear drive can also be selected.

[0035] Specifically, in this embodiment, the drive device 7 includes a drive motor fixed on the base 8 and a drive wheel located at the output end of the drive motor. One end of the roller shaft 2 is fixed with a driven wheel that is drively connected to the drive wheel. The drive wheel and the driven wheel are connected by a belt. Belt drive has the function of buffering and shock absorption, which can absorb some vibration and impact, making the rotation of the roller shaft 2 more stable. This helps to reduce noise and wear during equipment operation and extend the service life of the equipment.

[0036] The specific workflow of the aluminum sheet coiling fixture in the above embodiments is as follows:

[0037] First, manually rotate roller 2 to rotate the fixing structure 22 on roller 2 away from roller bearing assembly 4. Insert one end of the aluminum plate into the gap between the long groove 221 and the fixing rod 222, and wind and fix the aluminum plate. At this time, the two limiting plates 3 press the aluminum plate from both ends under the action of the elastic element 5. Next, rotate the handwheel to adjust the length of the first roller bearing 41 and the second roller bearing 42 of roller bearing assembly 4 to the same position as the distance between the two limiting plates 3. Then, start the drive device 7 to drive roller 2 to rotate and wind the aluminum plate. During the winding process, the aluminum plate automatically lifts roller bearing assembly 4 upward. Roller bearing assembly 4 applies a certain pressure to the aluminum plate roll through spring 9, pressing the aluminum plate roll radially until winding is completed.

[0038] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.

[0039] Furthermore, in this embodiment, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features.
