Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal waste recycling technology, specifically a rolling mill device for metal waste recycling. Background Technology
[0002] In the recycling of metal scrap, a rolling process is used to facilitate the storage of scrap. During the rolling process, the shearing force generated between the rollers causes the material to be squeezed and sheared multiple times, thereby increasing its plasticity. Based on further plasticization, it is stretched into thin products. The rolling mill is usually composed of two or more rollers, and the metal scrap can pass between the rollers to be rolled.
[0003] Current rolling mills lack the ability to limit the movement of rolled metal during operation. As a result, metal deviation is prone to occur during the rolling and traction process. This leads to uneven stress on the remaining metal during subsequent rolling, resulting in decreased ductility and ultimately, a rolling effect that does not meet expectations.
[0004] Therefore, we propose a rolling mill for metal scrap recycling to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a rolling device for recycling metal waste, including a base 1, a support 2 fixed to the top of the base 1, and a mounting base 3 connected to one side of the bottom of the support 2.
[0027] A first cylinder 4 is fixedly mounted on one end surface of the mounting base 3, and a first linkage rod 5 is connected to the end of the first cylinder 4 away from the mounting base 3. The two ends of the first cylinder 4 are rotatably connected to the mounting base 3 and the linkage rod respectively through connecting ears. One end of the first linkage rod 5 and the second linkage rod 12 are rotatably connected to the mounting base 3 through connecting ears. The other end of the first linkage rod 5 is connected to an adjustment frame 6, and a second cylinder 7 is fixedly mounted on the side wall of the adjustment frame 6. The output end of the second cylinder 7 is connected to a limit seat 8, and an auxiliary wheel 9 is rotatably connected to the inner side of the limit seat 8. The auxiliary wheels 9 are equidistantly distributed on the inner side of the limit seat 8, and the auxiliary wheels 9 are rotatably connected to the limit seat 8 through a bearing seat. A guide block 10 is fixedly mounted at the bottom of the limit seat 8, and a guide rod 11 passes through the inner side of the bottom of the guide block 10. The second linkage rod 12 is connected to the side of the adjustment frame 6 away from the first linkage rod 5, and a first motor 13 is fixedly mounted on the other side of the second linkage rod 12.
[0028] During operation, the mounting base 3 and the bracket 2 are pre-installed. Then, the operation of the first cylinder 4 drives the first linkage rod 5 and the second linkage rod 12 connected to its output end, causing the linkage rods on both sides to rotate around the mounting base 3 via connecting ears. As the linkage rods rotate, they drive the adjustment frame 6, connected to the other end via connecting ears, to adjust its position, facilitating better subsequent traction of the rolled metal scrap. Once the adjustment frame 6 is adjusted, the operation of the first motor 13 causes its output end, connected to the adjustment frame 6 via a rotating shaft, to rotate, thereby adjusting the angle of the adjustment frame 6. This allows the adjustment frame 6 to better traction the output metal scrap. This process is designed to better traction of the rolled metal scrap. The second cylinders 7, symmetrically arranged on both sides of the adjusting frame 6, drive the limiting seats 8 connected to their output ends, causing the limiting seats 8 to slide along the guide block 10 fixed at their bottom along the guide rod 11. This adjusts the distance between the two limiting seats 8. The guide block 10 improves the stability of the limiting seats 8 during lateral movement. After the positions of the two limiting seats 8 are adjusted, it is convenient to traction the rolled metal scrap. Since multiple auxiliary wheels 9 are evenly distributed on the inner side wall of the limiting seat 8, and the auxiliary wheels 9 are rotatably connected to the limiting seat 8, the multiple auxiliary wheels 9 can assist in the conveying of the rolled metal scrap, improve the stability of the metal scrap conveying process, and achieve the purpose of limiting.
[0029] like Figure 1 and Figure 4 As shown, in some embodiments, a second motor 14 is fixedly mounted on the side wall of the support 2, and the output end of the second motor 14 is connected to a first calendering roller 15. A hydraulic cylinder 16 is fixedly mounted at the middle of the top of the support 2, and the output end of the hydraulic cylinder 16 is connected to a lifting seat 17. A third motor 18 is fixedly mounted on the side wall of the lifting seat 17, and the output end of the third motor 18 is connected to a second calendering roller 19. One end of the second calendering roller 19 is connected to the third motor 18 through a rotating shaft, while the other end is rotatably connected to the lifting seat 17 through a bearing seat.
[0030] During operation, the hydraulic cylinder 16 is first used to longitudinally push the lifting seat 17 fixedly connected to its bottom. Then, the lifting seats 17 on both sides move longitudinally synchronously under the action of the hydraulic cylinder 16. The longitudinal movement of the lifting seats 17 is used to realize the gap between the second rolling roller 19 and the first rolling roller 15, which facilitates better rolling of the metal scrap in the subsequent process. During the rolling process, the second motor 14 and the third motor 18 will drive the first rolling roller 15 and the second rolling roller 19 to rotate respectively, which facilitates better rolling of the metal scrap in the subsequent process.
[0031] like Figure 3 and Figure 4 As shown, in some embodiments, a mounting groove 20 is provided on one side of the bottom of the bracket 2, and one end of the mounting groove 20 is connected to a lock hole 21. The lock holes 21 are symmetrically distributed along the vertical center line of the mounting groove 20. A return spring 22 is fixedly connected to the inner wall of the mounting base 3, and the other end of the return spring 22 is connected to a locking rod 23. The outer diameter of the locking rod 23 is adapted to the inner diameter of the lock hole 21, and the locking rod 23 is slidably connected to the mounting base 3 through the return spring 22. The two ends of the return spring 22 are respectively fixedly connected to one end of the locking rod 23 and the inner wall of the mounting base 3. An auxiliary slider 24 is sleeved on the outer side of one end of the locking rod 23.
[0032] During operation, the locking rod 23 is laterally pressed, causing it to laterally compress the return spring 22 and retract to the inside of the mounting base 3. Then, when the mounting base 3 is engaged with the mounting groove 20 on the side wall of the bracket 2, the locking rod 23 moves to one side of the lock hole 21. At this point, the center line of the locking rod 23 and the lock hole 21 are on the same horizontal line, and the lateral force applied to the locking rod 23 disappears. Then, the reverse force generated by the deformation of the return spring 22 pushes the locking rod 23 in the opposite direction, causing the locking rod 23 to drive the auxiliary slider 24 to slide inside the mounting base 3. This improves the stability of the locking rod 23 during lateral movement. Finally, when one end of the locking rod 23 is inserted into the inside of the lock hole 21, the mounting base 3 is positioned.
[0033] As shown in the figure Figure 2 As shown, in some embodiments, the two ends of the first cylinder 4 are rotatably connected to the mounting base 3 and the first linkage rod 5 respectively through connecting ears, and the first cylinder 4 is symmetrically distributed along the vertical center line of the adjusting frame 6.
[0034] During operation, since the two ends of the first cylinder 4 are rotatably connected to the first linkage rod 5 and the mounting base 3 respectively, when the first cylinder 4 works, it will push the first linkage rod 5, causing the first linkage rod 5 to rotate along the mounting base 3, which facilitates the subsequent adjustment of the position of the adjustment frame 6.
[0035] like Figure 2 As shown, in some embodiments, the limiting seat 8 is slidably connected to the guide rod 11 via the guide block 10, and the inner side of the guide block 10 is provided with a hole whose diameter is adapted to the guide rod 11.
[0036] During operation, when the limit seat 8 slides laterally inside the adjusting frame 6 under the action of the second cylinder 7, it will drive the guide block 10 to move laterally along the guide rod 11, thereby improving the stability of the limit seat 8 during the lateral movement.
[0037] In summary, during use, the mounting base 3 is pre-locked into the inner side of the mounting groove 20. Then, the locking rod 23 is used to position the mounting base 3. Next, the first cylinder 4 drives the first linkage rod 5 and the second linkage rod 12, causing the linkage rods on both sides to adjust the position of the adjusting frame 6. After the position of the adjusting frame 6 is adjusted, the first motor 13 rotates the adjusting frame 6 to adjust its angle. To better traction the rolled metal scrap, the second cylinder 7 drives the limiting seat 8, causing the limiting seat 8 to slide along the guide rod 11, thus adjusting the distance between the two limiting seats 8. Multiple auxiliary wheels 9 are evenly distributed on the inner side wall of the limiting seat 8, and the auxiliary wheels 9 are rotatably connected to the limiting seat 8. Therefore, the multiple auxiliary wheels 9 can be used to assist in the conveying of the rolled metal waste. After adjustment, the hydraulic cylinder 16 pushes the lifting seat 17. Then, the lifting seats 17 on both sides move synchronously longitudinally under the action of the hydraulic cylinder 16. The longitudinal movement of the lifting seats 17 is used to realize the distance between the second rolling roller 19 and the first rolling roller 15. During the rolling process, the second motor 14 and the third motor 18 will drive the first rolling roller 15 and the second rolling roller 19 to rotate respectively, which facilitates better subsequent rolling of the metal waste.
[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
