Description

Technical Field

[0001] This invention relates to the field of aluminum processing uncoiling devices, specifically to a cold-forming aluminum processing uncoiling device. Background Technology

[0002] Cold-formed aluminum, as an important metallic material, is widely used in construction decoration, transportation, electronics, and packaging industries due to its excellent formability, corrosion resistance, and lightweight yet high strength. In the continuous processing of aluminum, the uncoiling process, as the starting point of the entire production line, directly affects the processing effect and finished product quality of subsequent rolling, stamping, coating, and other processes, as well as the overall quality of the finished product.

[0003] The inner diameter of aluminum coils has certain manufacturing tolerances, and traditional mandrel structures lack effective radial adjustment capabilities, often resulting in situations where the fit between the inner hole and the shaft is too loose or too tight during installation. Too loose a fit can cause the aluminum coil to slip or rotate eccentrically during unwinding, affecting tension stability; too tight a fit leads to difficulties in assembly and disassembly, increases the workload of operators, and may damage the inner wall of the aluminum coil. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cold-forming aluminum processing uncoiling device that solves the problem of traditional mandrel structures lacking effective radial adjustment capabilities, often resulting in the aluminum coil having an excessively loose or excessively tight fit between the inner hole and the shaft during installation. Excessive looseness can easily cause the aluminum coil to slip or rotate eccentrically during uncoiling, affecting tension stability; excessive tightness leads to difficulties in assembly and disassembly, increases the labor intensity of operators, and may damage the inner wall of the aluminum coil.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cold-forming aluminum processing uncoiling device, comprising a pair of wall panels, a pair of housings fixedly installed between the pair of wall panels, a discharge port provided between the pair of housings, a pressing assembly provided inside the housings, an extension plate fixedly installed on one side wall of one of the pair of wall panels, a bearing box fixedly installed on the rear wall of the extension plate, a bearing roller rotatably installed on the extension plate, the rear end of the bearing roller penetrating through the extension plate and located inside the bearing box, a driving assembly provided between the bearing box and the rear end of the bearing roller, and a support assembly provided on the bearing roller.

[0006] Preferably, the clamping assembly includes a U-shaped plate, with a pair of through holes respectively opened on the opposite walls of the box body, the vertical end of the U-shaped plate passing through the through hole, and a pressure roller rotatably installed between the through ends of the U-shaped plate. Slide rails are fixedly installed on the two inner walls of the box body respectively, and sliders are slidably installed in the slide rails. The U-shaped plate is fixedly installed between the sliders, and several springs are fixedly installed between the lateral end of the U-shaped plate and the inner wall of the box body away from the wall with the through hole.

[0007] Preferably, the drive assembly includes a first motor, which is fixedly installed on the rear wall of the carrier box. Pulleys are fixedly installed on the drive end of the first motor and the rear end of the carrier roller, respectively, and a transmission belt is connected between the pulleys.

[0008] Preferably, the support assembly includes a second motor and a pair of moving blocks. The second motor is fixedly installed on the outer rear wall of the bearing roller. The bearing roller has an inner cavity and three openings. The drive end of the second motor passes through the rear wall of the bearing roller. A bidirectional lead screw is fixedly installed on the drive end of the second motor. The other end of the bidirectional lead screw is rotatably installed on the front wall of the inner cavity. The moving blocks have threaded holes and are engaged with the bidirectional lead screw through the threaded holes. Three support rods are hinged to the moving blocks, and a top plate is hinged between the support rods.

[0009] Preferably, the included angle between the adjacent openings is 120 degrees.

[0010] Preferably, a limiting rod is fixedly installed on the top plate on both sides of the support rod, and a limiting hole is opened on the bearing roller on both sides of the opening. The limiting rod passes through the limiting hole and a limiting plate is fixedly installed at its lower end.

[0011] Preferably, a pair of bearing plates are fixedly installed on the extension plate between the bearing roller and the discharge port, and brushes are fixedly installed on the opposite wall surfaces of the bearing plates.

[0012] Beneficial effects This invention provides a cold-forming aluminum processing uncoiling device, solving the problem that traditional mandrel structures lack effective radial adjustment capabilities, often resulting in either excessively loose or excessively tight fits between the inner hole and the shaft during aluminum coil installation. Excessive looseness can cause the aluminum coil to slip or rotate eccentrically during uncoiling, affecting tension stability; excessive tightness leads to difficult assembly and disassembly, increasing the labor intensity of operators and potentially damaging the inner wall of the aluminum coil. This invention achieves rapid and precise clamping and support of aluminum coils with different inner diameters through a support component installed within the carrying roller. Specifically, a second motor drives a bidirectional lead screw to rotate, causing a pair of moving blocks to move in opposite directions, which in turn pushes three top plates to expand or contract synchronously radially via a hinged support rod. This design allows the device to adapt to the actual dimensions of the aluminum coil's inner hole, effectively overcoming fit problems caused by manufacturing tolerances. The top plates are evenly distributed at 120-degree angles, ensuring balanced support and preventing eccentric swaying or slippage of the aluminum coil during high-speed unwinding. Compared to traditional fixed mandrel or sleeve replacement solutions, this device significantly shortens coil changeover time and reduces operator workload, while providing a solid support foundation for stable unwinding. The invention features a clamping assembly within a pair of housings, which continuously applies pressure to the U-shaped plate and pressure rollers via springs, ensuring the aluminum strip is always under stable clamping force at the outlet. This elastic clamping structure automatically compensates for changes in aluminum coil diameter and strip thickness fluctuations. This invention provides continuous and uniform tension control, effectively preventing strip wrinkling and stacking caused by tension slack during unwinding, or tensile deformation caused by excessive tension. Simultaneously, the close contact between the pressure roller and the aluminum coil surface helps guide the strip along a predetermined path, providing a certain degree of automatic correction for slight deviations, reducing production interruptions and scrap rates, and significantly improving the stability of the unwinding process and product quality. The drive assembly of this invention uses a motor coupled with a pulley and a transmission belt, resulting in a compact structure and smooth transmission, ensuring uniform rotation of the carrier roller and the aluminum coil, providing reliable power for controllable unwinding speed. Furthermore, an innovative pair of carrier plates with brushes are installed between the carrier roller and the discharge port. This brush structure can... During the unwinding process of aluminum strip, dust, aluminum shavings, and other impurities attached to its surface are directly brushed off, achieving simultaneous unwinding and preliminary cleaning. This integrated design eliminates the need for a separate subsequent cleaning process, simplifies the production flow, saves equipment space, and provides clean raw materials for subsequent high-quality rolling or coating processes. The main body of the device uses wall panels and a box to form a stable frame. The bearing rollers are equipped with limiting rods and limiting holes to ensure precise guidance and limiting of the top plate during radial movement, preventing unexpected displacement or torsion of the support structure. The overall structure is rigid and stable. This device is suitable for high-speed, continuous industrial production environments in cold-forming aluminum processing, with low operating noise, convenient maintenance, and long service life.

[0019] Please see Figure 1-4 The present invention provides a technical solution: a cold-forming aluminum processing uncoiling device, comprising a pair of wall plates 1, a pair of housings 2 fixedly installed between the pair of wall plates 1, a discharge port 3 provided between the pair of housings 2, a pressing assembly provided inside the housings 2, an extension plate 4 fixedly installed on one side wall of the pair of wall plates 1, a bearing box 5 fixedly installed on the rear wall of the extension plate 4, a bearing roller 6 rotatably installed on the extension plate 4, the rear end of the bearing roller 6 passing through the extension plate 4 and located inside the bearing box 5, a driving assembly provided between the bearing box 5 and the rear end of the bearing roller 6, and a support assembly provided on the bearing roller 6.

[0020] In this embodiment, the pressing assembly includes a U-shaped plate 7, and a pair of through holes are respectively opened on the opposite walls of the box body 2. The vertical end of the U-shaped plate 7 passes through the through hole, and a pressure roller 8 is rotatably installed between the through ends of the U-shaped plate 7. Slide rails 9 are fixedly installed on the two inner walls of the box body 2, and sliders 10 are slidably installed in the slide rails 9. The U-shaped plate 7 is fixedly installed between the sliders 10, and a plurality of springs 11 are fixedly installed between the horizontal end of the U-shaped plate 7 and the inner wall of the box body 2 away from the wall with the through hole.

[0021] In this embodiment, the driving component includes a first motor 12, which is fixedly installed on the rear wall of the bearing box 5. Pulleys 13 are fixedly installed on the driving end of the first motor 12 and the rear end of the bearing roller 6, respectively, and a transmission belt 14 is connected between the pulleys 13.

[0022] In this embodiment, the support assembly includes a second motor 15 and a pair of moving blocks 16. The second motor 15 is fixedly installed on the outer rear wall of the bearing roller 6. The bearing roller 6 has an inner cavity 17 and three openings 18. The driving end of the second motor 15 passes through the rear wall of the bearing roller 6. A bidirectional lead screw 19 is fixedly installed on the driving end of the second motor 15. The other end of the bidirectional lead screw 19 is rotatably installed on the inner front wall of the inner cavity 17. The moving blocks 16 have threaded holes and are engaged with the bidirectional lead screw 19 through the threaded holes. Three support rods 20 are hinged to the moving blocks 16, and a top plate 21 is hinged between the support rods 20.

[0023] In this embodiment, the included angle between the adjacent openings 18 is 120 degrees.

[0024] In this embodiment, the limiting rods 22 are fixedly installed on the top plate 21 on both sides of the support rod 20, and the bearing roller 6 is provided with limiting holes on both sides of the opening 18. The limiting rods 22 pass through the limiting holes and the lower end is fixedly installed with a limiting plate 23.

[0025] In this embodiment, a pair of bearing plates 24 are fixedly installed on the extension plate 4 and between the bearing roller 6 and the discharge port 3, and brushes 25 are fixedly installed on the opposite wall surfaces of the bearing plates 24.

[0026] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0027] Example: As shown in the accompanying drawings, during use, a forklift transports the coiled aluminum to the vicinity of the bearing roller 6, and the forklift inserts the center of the aluminum coil into the bearing roller 6. At this time, the second motor 15 is started, and the second motor 15 drives the bidirectional lead screw 19 to rotate. Since the moving block 16 is connected to the bidirectional lead screw 19 through a threaded hole, the rotation of the bidirectional lead screw 19 drives the moving block 16. At this time, the moving block 16 moves towards each other, thereby causing the support rod 20 to perform a supporting movement, thereby supporting and opening the top plate 21, so that the top plate 21 contacts the inner wall of the aluminum coil, thereby supporting and fixing the inner diameter of the aluminum coil. During the movement, the top plate 21 moves along the limit rod 22. Moving along the path of the limiting hole, the aluminum coil passes through the brush 25 and between the pressure rollers 8. The pressure rollers 8 are pushed by the aluminum coil, which in turn pushes the U-shaped plate 7. Under the action of the slider 10, the U-shaped plate 7 moves along the path of the slide rail 9, which in turn squeezes the spring 11. Due to the principle of mutual action of forces, the spring 11 pushes the U-shaped plate 7, which in turn squeezes the aluminum coil. At this time, the first motor 12 is started. Since the drive end of the first motor 12 and the rear end of the bearing roller 6 are respectively fixedly installed with pulleys 13, and the pulleys 13 are connected by a transmission belt 14, when the first motor 12 is started, the bearing roller 6 rotates, which in turn causes the aluminum coil to unwind.
