Description

Technical Field

[0001] This utility model belongs to the field of aluminum strip drawing, and specifically relates to a multi-roll rolling device for aluminum strip drawing. Background Technology

[0002] In modern industrial production, metal wire drawing is highly favored for its ability to impart aesthetic appeal and corrosion resistance to products. This is especially true in the aluminum processing industry, where aluminum strip wire drawing is widely used in the manufacture of metal casings for numerous products. Metal wire drawing involves processes such as degreasing, sand milling, and washing. After these processes, the aluminum strip surface undergoes anodizing to form a special film layer, resulting in a brilliant, hair-like sheen. With the development of related industries, higher demands are being placed on the quality and efficiency of aluminum strip wire drawing, necessitating advanced rolling equipment to meet production needs.

[0003] Existing technologies have specifically developed some multi-roll rolling devices for aluminum strip drawing. For example, Chinese Patent No. CN207565219U discloses "An Aluminum Strip Surface Drawing Device". This utility model has a simple structure, flexible adjustment, improves the drawing quality and drawing efficiency of aluminum strip, and can be used for drawing aluminum strips of different thicknesses, improving the drawing effect of aluminum strip surface and meeting people's production needs for aluminum strip surface drawing.

[0004] Although the flexible adjustment improves the drawing quality and efficiency of aluminum strips and makes it applicable to drawing aluminum strips of different thicknesses, thus improving the drawing effect on the aluminum strip surface and meeting people's production needs for aluminum strip surface drawing, the above structure cannot effectively adjust the mounting base. This greatly reduces the difficulty and practicality of adjustment when the mounting base needs to be adjusted during processing. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a multi-roll rolling device for aluminum strip drawing, so as to solve the problem of aluminum strip drawing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A multi-roll rolling device for drawing aluminum strip includes a worktable. Fixed plates are fixedly installed on both sides of the upper end of the worktable. Multiple conveying rollers are rotatably installed between the two sets of fixed plates. Rectangular plates are fixedly installed on both sides of the upper end of the worktable. A guide rod is fixedly installed inside one side of the rectangular plate, and a second drive motor is fixedly installed on one side of the other rectangular plate. A threaded rod is fixedly installed on the output shaft of the second drive motor, and the threaded rod rotates inside the rectangular plate. Moving plates are slidably installed inside both rectangular plates. A cylinder is fixedly installed at the center of the upper end of each moving plate. A sliding block is fixedly installed on the output shaft of each cylinder. Both sliding blocks slide inside the moving plates. An upper roller shaft is rotatably installed between the two sliding blocks. A first drive motor is fixedly installed on the opposite sides of both moving plates. A drive gear is fixedly installed on the output shaft of the first drive motor. Two lower roller shafts are rotatably installed on both sides of the bottom of both moving plates. Driven gears are fixedly installed on the opposite sides of the two lower roller shafts, and the driven gears mesh with the drive gears.

[0008] As a preferred technical solution, a support frame is fixedly installed around the bottom of the workbench, and rectangular slots are opened inside the two rectangular plates. The guide rod is fixedly installed inside one of the rectangular plates through the rectangular slots, and the threaded rod is rotatably installed inside the other rectangular plate through the rectangular slots opened inside the other rectangular plate.

[0009] As a preferred technical solution, both of the movable plates have a rectangular slider integrally formed at their bottom. One of the rectangular sliders has a guide groove inside, and the other rectangular slider has an internal thread groove inside. The threaded rod is threadedly connected to the rectangular slider through the internal thread groove, and the rectangular slider is sleeved on the outer ring of the guide rod through the guide groove inside.

[0010] As a preferred technical solution, a first rotating shaft is fixedly installed at both ends of the two lower roller shafts, and the first rotating shaft is rotatably installed on both sides inside the moving plate. A second rotating shaft is fixedly installed at both ends of the upper roller shaft, and the second rotating shaft is rotatably installed inside the sliding block.

[0011] As a preferred technical solution, both of the movable plates are provided with sliding grooves, and the sliding block is slidably installed inside the movable plate through the sliding grooves. Limiting grooves are provided on both sides of the sliding grooves, and limiting rods are fixedly installed inside the limiting grooves.

[0012] As a preferred technical solution, limit blocks are fixedly installed on both sides of the two sliding blocks, and a limiting groove is opened inside the limit blocks on both sides. The limit blocks are slidably installed inside the limiting grooves, and the limit blocks are sleeved on the outer ring of the limiting rod through the limiting grooves opened inside.

[0013] As a preferred technical solution, the output shafts of the first drive motors on both sides are fixedly mounted with drive gears through the moving plate, and a driven gear is fixedly mounted on one side of one of the lower roller shafts, while a driven gear is also fixedly mounted on the other lower roller shaft at the end away from the first lower roller shaft.

[0014] In summary, the present invention has the following main advantages:

[0015] After the first and second drive motors start, they drive the threaded rod to rotate. Since the threaded rod is threadedly connected to the internal thread groove of the rectangular slider at the bottom of the moving plate, and the rectangular slider is sleeved on the guide rod through the guide groove, the rotation of the threaded rod will cause the moving plate to move horizontally in a straight line along the guide rod. By controlling the forward and reverse rotation and rotation angle of the second drive motor, the horizontal position of the moving plate can be precisely adjusted to adapt to the rolling requirements of aluminum strips of different widths.

[0016] Secondly, the extension and retraction of the cylinder causes the sliding block to slide up and down in the sliding groove inside the moving plate. The up and down movement of the sliding block changes the distance between the upper and lower roller shafts, thereby adjusting the thickness of the aluminum strip. The precise control of the cylinder ensures the vertical position adjustment accuracy of the upper roller shaft, which can meet the rolling requirements of aluminum strips of different thicknesses. After the first drive motor starts, the drive gear on its output shaft drives the driven gear meshing with it to rotate, thereby rotating the lower roller shaft. The rotation of the lower roller shaft drives the aluminum strip to move through friction. At the same time, the upper roller shaft also rotates under the drive of the aluminum strip. This driving method ensures the synchronous rotation of the upper and lower roller shafts, improving the quality of aluminum strip rolling. Attached Figure Description

Detailed Implementation

[0024] Example

[0025] refer to Figures 1-6 This embodiment of a multi-roll rolling device for aluminum strip drawing includes a worktable 11. Fixed plates 5 are fixedly installed on both sides of the upper end of the worktable 11. Multiple conveying rollers 12 are rotatably installed between the two sets of fixed plates 5. Rectangular plates 9 are fixedly installed on both sides of the upper end of the worktable 11. A guide rod 19 is fixedly installed inside one rectangular plate 9, and a second drive motor 10 is fixedly installed on one side of the other rectangular plate 9. A threaded rod 17 is fixedly installed on the output shaft of the second drive motor 10, rotating inside the rectangular plate 9. Sliding installations are also provided inside both rectangular plates 9. There is a movable plate 4, and a cylinder 1 is fixedly installed at the center of the upper end of the movable plate 4. A sliding block 15 is fixedly installed on the output shaft of the cylinder 1. Both sliding blocks 15 slide inside the movable plate 4. An upper roller shaft 2 is rotatably installed between the two sliding blocks 15. A first drive motor 7 is fixedly installed on the opposite side of the two movable plates 4. A drive gear 22 is fixedly installed on the output shaft of the first drive motor 7. Two lower roller shafts 3 are rotatably installed on both sides of the bottom of the two movable plates 4. A driven gear 18 is fixedly installed on the opposite side of the two lower roller shafts 3. The driven gear 18 meshes with the drive gear 22.

[0026] refer to Figure 2The workbench 11 has support frames 6 fixedly installed around its bottom. Two rectangular plates 9 each have rectangular grooves 13 inside. A guide rod 19 is fixedly installed inside one of the rectangular plates 9 through the rectangular grooves 13. A threaded rod 17 is rotatably installed inside the other rectangular plate 9 through the rectangular groove 13 inside the other rectangular plate 9. Both movable plates 4 have integrally formed rectangular sliders 20 at their bottoms. One rectangular slider 20 has a guide groove 21 inside, and the other rectangular slider 20 has an internal threaded groove 16 inside. The threaded rod 17 is threadedly connected to the rectangular slider 20 through the internal threaded groove 16. The rectangular slider 20 is sleeved on the outer ring of the guide rod 19 through the internal guide groove 21. After the second drive motor 10 is started, it drives the threaded rod 17 to rotate. Since the threaded rod 17 is threadedly connected to the internal thread groove 16 of the rectangular slider 20 at the bottom of the moving plate 4, and the rectangular slider 20 is sleeved on the guide rod 19 through the guide groove 21, the rotation of the threaded rod 17 will cause the moving plate 4 to move horizontally along the guide rod 19. By controlling the forward and reverse rotation and rotation angle of the second drive motor 10, the horizontal position of the moving plate 4 can be precisely adjusted to adapt to the rolling requirements of aluminum strips of different widths.

[0027] refer to Figure 1 , Figures 3 to 4 Two lower rollers 3 are each fixedly mounted with a first rotating shaft 8 at both ends. The first rotating shaft 8 is rotatably mounted inside both sides of the moving plate 4. Two upper rollers 2 are each fixedly mounted with a second rotating shaft 23 at both ends. The second rotating shaft 23 is rotatably mounted inside the sliding block 15. Both moving plates 4 have sliding grooves 14 inside. The sliding block 15 is slidably mounted inside the moving plate 4 through the sliding grooves 14. Limiting grooves 26 are opened on both sides of the sliding grooves 14. Limiting rods 27 are fixedly installed inside the limiting grooves 26. The extension and retraction of the cylinder 1 causes the sliding block 15 to slide up and down in the sliding grooves 14 inside the moving plate 4. The up and down movement of the sliding block 15 will change the distance between the upper roller 2 and the lower roller 3, thereby adjusting the thickness of the aluminum strip rolling.

[0028] refer to Figures 3 to 5Limiting blocks 24 are fixedly installed on both sides of the two sliding blocks 15. Limiting grooves 25 are opened inside the limiting blocks 24 on both sides. The limiting blocks 24 are slidably installed inside the limiting grooves 26. The limiting blocks 24 are sleeved on the outer ring of the limiting rod 27 through the limiting grooves 25. The output shafts of the first drive motors 7 on both sides are fixedly installed with drive gears 22 through the moving plate 4. One side of the lower roller shaft 3 is fixedly installed with a driven gear 18, and the other lower roller shaft 3 is also fixedly installed with a driven gear 18 at the end away from the first lower roller shaft 3. After the first drive motor 7 is started, the drive gear 22 on its output shaft drives the driven gear 18 that meshes with it to rotate, thereby rotating the lower roller shaft 3. The rotation of the lower roller shaft 3 drives the aluminum strip to move through friction. At the same time, the upper roller shaft 2 also rotates under the drive of the aluminum strip. This driving method ensures the synchronous rotation of the upper roller shaft 2 and the lower roller shaft 3, and improves the quality of aluminum strip rolling.

[0029] Operating principle and advantages: During operation, the conveyor rollers 12 rotate under the drive of the motor, driving the aluminum strip forward on the worktable 11. The arrangement of multiple conveyor rollers 12 ensures the stability and continuity of aluminum strip conveying, providing a good foundation for subsequent rolling processes. The surface of the conveyor rollers 12 is usually specially treated to increase the friction with the aluminum strip and prevent the aluminum strip from slipping during conveying. After the second drive motor 10 starts, it drives the threaded rod 17 to rotate. Since the threaded rod 17 is threadedly connected to the internal thread groove 16 of the rectangular slider 20 at the bottom of the moving plate 4, and the rectangular slider... 20 is sleeved on guide rod 19 through guide groove 21. Therefore, the rotation of threaded rod 17 will cause moving plate 4 to move horizontally along guide rod 19. By controlling the forward and reverse rotation and rotation angle of second drive motor 10, the horizontal position of moving plate 4 can be precisely adjusted to adapt to the rolling requirements of aluminum strips of different widths. The telescopic movement of cylinder 1 drives sliding block 15 to slide up and down in sliding groove 14 inside moving plate 4. The up and down movement of sliding block 15 will change the distance between upper roller shaft 2 and lower roller shaft 3, thereby realizing the adjustment of aluminum strip rolling thickness. Cylinder 1 Precise control ensures the vertical position adjustment accuracy of the upper roller 2, meeting the rolling requirements of aluminum strips of different thicknesses. After the first drive motor 7 starts, the drive gear 22 on its output shaft drives the driven gear 18 meshing with it to rotate, thereby rotating the lower roller 3. The rotation of the lower roller 3 drives the aluminum strip to move through friction. At the same time, the upper roller 2 also rotates under the drive of the aluminum strip. This driving method ensures the synchronous rotation of the upper roller 2 and the lower roller 3, improving the quality of aluminum strip rolling. The setting of multiple lower rollers 3 increases the contact area between the aluminum strip and the rollers, making the rolling process more efficient. The force distribution is more uniform, further improving the rolling effect. The limiting blocks 24 on both sides of the sliding block 15 are slidably installed in the limiting grooves 26 on both sides of the sliding groove 14, and the limiting blocks 24 are sleeved on the limiting rod 27 through the internal limiting groove 25. This structural design not only limits the movement of the sliding block 15 and prevents it from deviating during the movement, but also plays a guiding role, ensuring that the sliding block 15 slides smoothly in the sliding groove 14. At the same time, the cooperation between the limiting rod 27 and the limiting groove 25 can also withstand a certain lateral force, improving the stability and reliability of the device.
