Description

Technical Field

[0001] This utility model belongs to the field of aluminum rod production technology, specifically relating to an aluminum rod alignment device used in an aluminum rod continuous casting production line. Background Technology

[0002] Aluminum rods are metal products refined from aluminum ore through a smelting process. They are usually in rod shape, such as round rods or square rods.

[0003] In the production line of square-shaped aluminum bars, in order to facilitate the use of the stacking device, it is necessary to ensure that the aluminum bars are kept in the center position on the conveyor line for transportation. When the aluminum bars are manually placed on the conveyor line one by one for transportation, the posture of the aluminum bars cannot be uniform, such as tilting or not being centered. These problems will inevitably lead to non-standard and uneven stacking later. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an aluminum bar alignment device for an aluminum bar continuous casting production line. This application can align and adjust aluminum bars that are tilted and not centered on the conveyor belt, so as to facilitate standardized and neat stacking later.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An aluminum bar alignment device for use in an aluminum bar continuous casting production line, comprising:

[0007] The base has a gantry frame fixedly connected to its upper end. Two cylinders are fixedly connected to the gantry frame. A lifting plate is fixedly connected to the piston rods of the two cylinders. A rotating shaft is rotatably connected to the lifting plate. A rectangular frame is fixedly connected to the lower end of the rotating shaft. Five equally spaced connecting plates are arranged on one side of the rectangular frame. The connecting plate in the middle is fixedly connected to the rectangular frame. A driving block is fixedly connected to the side of the other four connecting plates. At least two guide rods are slidably connected to each driving block. The two ends of the guide rods are fixedly connected to the inner wall of the rectangular frame. A first rack is fixedly connected to the two driving blocks near the end of the rectangular frame. A first gear meshes between the two first racks. A second rack is fixedly connected to the other two driving blocks. A second gear with a diameter smaller than the first gear meshes between the two second racks. The second gear is fixedly connected to the outer side of the first gear. A lifting plate is fixedly connected to the lower end of the connecting plate. Clamping plates are fixedly connected to the side of the two outermost connecting plates.

[0008] A conveyor belt is located below a rectangular frame. Drive rollers are provided on the inner sides of both ends of the conveyor belt. Four equally spaced protrusions are fixedly connected to the conveyor belt, and the protrusions are located between two adjacent lifting plates.

[0009] The principles and technical effects of the above technical solution are as follows:

[0010] The drive source drives the transmission roller to rotate, which in turn drives the conveyor belt. Aluminum bars are spaced apart on the conveyor belt and mounted on raised supports. As the aluminum bars are conveyed, they move towards the connecting plate. Any unevenly placed aluminum bars contact the connecting plate and are straightened under its constraint. Then, two cylinders simultaneously drive the piston rods to retract, causing the lifting plate to move upwards. The lifting plate moves the rotating shaft upwards, which in turn moves the rectangular frame upwards. The rectangular frame then moves the connecting plate and the lifting plate upwards, lifting the aluminum bars and detaching them from the conveyor belt. Simultaneously, the drive source drives the first gear and the second gear to rotate synchronously. The first gear moves the two first racks, which in turn move the two drive blocks connected to them towards the center. The two drive blocks then move the two outermost connecting plates and the lifting plate towards the center. The second gear... The wheel drives two second gears to move, which in turn drive two connected drive blocks to move towards the center. The two drive blocks then drive the remaining two connecting plates and lifting plates to move towards the center. Except for the central connecting plate and lifting plate, which remain stationary, the remaining connecting plates and lifting plates move towards the center until the two clamping plates contact the ends of the aluminum rod, clamping the aluminum rod. This process centers and aligns the aluminum rod. Then, after the rectangular frame rotates in the opposite direction, the drive source drives the first and second gears to rotate synchronously in the opposite direction, resetting the connecting plates and lifting plates. Simultaneously, the two cylinders drive the piston rods to move downwards, causing the lifting plate to move downwards until the lifting plate is located in the groove between the convex strips. After the aluminum rod contacts the convex strips on the conveyor belt, it continues to move with the conveyor belt. At this point, the aluminum rod has been aligned and is centered on the conveyor belt.

[0011] Furthermore, the pivot is located at the exact center of the rectangular frame.

[0012] Furthermore, a third gear is fixedly connected to the rotating shaft, and a fourth gear meshes with the circumference of the third gear. The fourth gear is fixedly connected to the output end of the first motor, and the first motor is fixedly connected to the lifting plate.

[0013] Furthermore, a fixed bracket is fixedly connected to the inner side of the rectangular frame, and a second motor is fixedly connected to the fixed bracket. The output end of the second motor is fixedly connected to the first gear and the second gear.

[0014] Furthermore, the circumference of the first gear is twice the circumference of the second gear.

[0015] Furthermore, the two ends of the transmission roller are rotatably connected to a first support plate, the first support plate is fixedly connected to the base, one end of one of the transmission rollers is fixedly connected to the output end of a third motor, and the third motor is fixedly connected to the first support plate.

[0016] Furthermore, a smooth support plate is provided on the inner side of the conveyor belt, the upper end surface of the smooth support plate is in contact with the conveyor belt, and a second support plate is fixedly connected to both sides of the smooth support plate, the second support plate being fixedly connected to the base.

[0017] Furthermore, the thickness of the convex strip is greater than the thickness of the lifting plate.

[0018] Furthermore, a reinforcing plate is fixedly connected between the lifting plate and the connecting plate.

[0019] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0020] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0021] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0022] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly is required by forging, sawing, or oxy-acetylene cutting during repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.

[0023] A threaded connection is a detachable connection in which threaded parts (or the threaded portion of the connected parts) are joined together as one unit.

[0024] A sliding connection refers to two objects that are in contact but not fixed, and can slide relative to each other.

[0025] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0026] The beneficial effects of this utility model are:

[0027] This application can align and adjust aluminum bars that are tilted and off-center when placed on a conveyor belt, making it easier to stack them neatly and orderly in the future. Attached Figure Description

[0034] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0036] Based on the concept of this application, combined with Figures 1 to 5This describes an embodiment of an aluminum bar alignment device for use in an aluminum bar continuous casting production line. Specifically, the aluminum bar alignment device for the aluminum bar continuous casting production line is constructed as a split structure, which has a base 1, a gantry frame 2, a rectangular frame 7, a connecting plate 8, a conveyor belt 17, and a lifting plate 15, etc., which cooperate with each other. A drive source drives a transmission roller 18 to rotate, and the transmission roller 18 drives the conveyor belt 17 to move. Aluminum bars are placed at intervals on the conveyor belt 17. The aluminum bars are mounted on a convex strip 19. The aluminum bars move towards the connecting plate 8 under the conveyor belt 17. After the misaligned aluminum bars come into contact with the connecting plate 8, they are aligned. Under the constraint of plate 8, the plate is straightened. Then, the two cylinders 3 simultaneously drive the piston rod 4 to retract, causing the lifting plate 5 to move upward. The lifting plate 5 drives the rotating shaft 6 to move upward, the rotating shaft 6 drives the rectangular frame 7 to move upward, and the rectangular frame 7 drives the connecting plate 8 and the lifting plate 15 to move upward. The lifting plate 15 lifts the aluminum rod upward and removes it from the conveyor belt 17. At the same time, the drive source drives the first gear 12 and the second gear 14 to rotate synchronously. The first gear 12 drives the two first racks 11 to move, and the two first racks 11 drive the two drive blocks 9 connected to them to move... The two drive blocks 9 move the two outermost connecting plates 8 and lifting plates 15 towards the center. The second gear 14 drives two second gears 14 to move, which in turn drive the two drive blocks 9 connected to them to move towards the center. The two drive blocks 9 then drive the remaining two connecting plates 8 and lifting plates 15 towards the center. Except for the central connecting plate 8 and lifting plate 15, which remain stationary, the remaining connecting plates 8 and lifting plates 15 all move towards the center until the two clamping plates 16 contact the ends of the aluminum rod, clamping the aluminum rod. The process involves centering the aluminum rod, then rotating the rectangular frame 7 180 degrees to reverse its orientation. The drive source then drives the first gear 12 and the second gear 14 to rotate synchronously in the opposite direction, resetting the connecting plate 8 and the lifting plate 15. Simultaneously, the two cylinders 3 drive the piston rod 4 to move downwards, causing the lifting plate 5 to move downwards until the lifting plate 15 is located in the groove between the protrusions 19. After the aluminum rod contacts the protrusions 19 on the conveyor belt 17, it continues to move with the conveyor belt 17. At this point, the aluminum rod has been centered on the conveyor belt 17.

[0037] like Figures 1 to 5 As shown, an aluminum bar alignment device for use in an aluminum bar continuous casting production line includes:

[0038] A base 1 has a gantry frame 2 fixedly connected to its upper end. Two cylinders 3 are fixedly connected to the gantry frame 2. A lifting plate 5 is fixedly connected to the piston rods 4 of the two cylinders 3. A rotating shaft 6 is rotatably connected to the lifting plate 5. A rectangular frame 7 is fixedly connected to the lower end of the rotating shaft 6. Five equally spaced connecting plates 8 are provided on one side of the rectangular frame 7. The central connecting plate 8 is fixedly connected to the rectangular frame 7. Drive blocks 9 are fixedly connected to the sides of the other four connecting plates 8. At least two guide rods 10 are slidably connected to each drive block 9. Both ends are fixedly connected to the inner wall of the rectangular frame 7. Two drive blocks 9 near the ends of the rectangular frame 7 are fixedly connected to the first rack 11. A first gear 12 meshes between the two first racks 11. Two other drive blocks 9 are fixedly connected to the second rack 13. A second gear 14 with a diameter smaller than the first gear 12 meshes between the two second racks 13. The second gear 14 is fixedly connected to the outer side of the first gear 12. A lifting plate 15 is fixedly connected to the lower end of the connecting plate 8. Clamping plates 16 are fixedly connected to the sides of the two outermost connecting plates 8.

[0039] The conveyor belt 17 is located below the rectangular frame 7. The inner sides of both ends of the conveyor belt 17 are provided with drive rollers 18. Four equally spaced protrusions 19 are fixedly connected to the conveyor belt 17. The protrusions 19 are located between two adjacent lifting plates 15.

[0040] In operation, the drive source drives the transmission roller 18 to rotate, which in turn drives the conveyor belt 17. Aluminum bars are spaced apart on the conveyor belt 17 and mounted on the convex strips 19. The aluminum bars move towards the connecting plate 8 under the conveyor belt 17. Any unevenly placed aluminum bars come into contact with the connecting plate 8 and are straightened under its constraint. Then, the two cylinders 3 simultaneously drive the piston rods 4 to retract, causing the lifting plate 5 to move upwards. The lifting plate 5 then drives the rotating shaft 6 to move upwards, which in turn drives the rectangular frame 7 to move upwards. The rectangular frame 7 then drives the connecting plate 8 and the lifting plate 15 to move upwards. The lifting plate 15 lifts the aluminum bars upwards, separating them from the conveyor belt 17. Simultaneously, the drive source drives the first gear 12 and the second gear 14 to rotate synchronously. The first gear 12 drives the two first racks 11 to move, which in turn drive the two connected drive blocks 9 to move towards the center. The two drive blocks 9 then drive the two outermost connecting plates 8 and the lifting plate 15 to move towards the center. The second gear 14 drives two second gears 14 to move, and the two second gears 14 drive two drive blocks 9 connected to them to move towards the center. The two drive blocks 9 drive the remaining two connecting plates 8 and lifting plates 15 to move towards the center. Except for the connecting plate 8 and lifting plate 15 in the very center which are fixed, the remaining connecting plates 8 and lifting plates 15 all move towards the center until the two clamping plates 16 contact the end of the aluminum rod and clamp the aluminum rod. This process centers and straightens the aluminum rod. Then, after the rotating rectangular frame 7 rotates 180 degrees and reverses, the drive source drives the first gear 12 and the second gear 14 to rotate synchronously in the opposite direction. The connecting plates 8 and lifting plates 15 are reset. At the same time, the two cylinders 3 drive the piston rod 4 to move down and move the lifting plate 5 down until the lifting plate 15 is located in the groove between the protrusions 19. After the aluminum rod contacts the protrusions 19 on the conveyor belt 17, it continues to move with the conveyor belt 17. At this time, the aluminum rod has been straightened and is centered on the conveyor belt 17.

[0041] The upper sides of the lifting plate 15 are curved to prevent the ends of the aluminum rods from contacting the sides of the lifting plate 15. Of course, in the initial design, the upper surfaces of all the lifting plates 15 were flush.

[0042] In one embodiment of this invention, the rotating shaft 6 is located at the exact center of the rectangular frame 7. The vertical projection of the rotating shaft 6 onto the conveyor belt 17 is equidistant from both sides of the conveyor belt 17. This arrangement ensures that the aluminum rod, once aligned, is positioned as centrally as possible on the conveyor belt 17.

[0043] In one embodiment of this utility model, a third gear 20 is fixedly connected to the rotating shaft 6, and a fourth gear 21 meshes with the peripheral side of the third gear 20. The fourth gear 21 is fixedly connected to the output end of the first motor 22, which is fixedly connected to the lifting plate 5. The first motor 22 acts as a drive source to drive the fourth gear 21 to rotate, which in turn drives the third gear 20 to rotate. The third gear 20 then drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the rectangular frame 7 to rotate 180 degrees.

[0044] In one embodiment of this utility model, a fixed bracket 23 is fixedly connected to the inner side of the rectangular frame 7, and a second motor 24 is fixedly connected to the fixed bracket 23. The output end of the second motor 24 is fixedly connected to the first gear 12 and the second gear 14. The second motor 24 is used to drive the first gear 12 and the second gear 14 to rotate simultaneously. The second motor 24 acts as a drive source to drive the first gear 12 and the second gear 14 to rotate synchronously, thereby realizing the movement of the connecting plate 8 and the lifting plate 15.

[0045] In one embodiment of this invention, the circumference of the first gear 12 is twice the circumference of the second gear 14. When the lifting plates 15 move towards the center, the spacing between all adjacent lifting plates 15 remains the same.

[0046] In one embodiment of this utility model, the two ends of the transmission roller 18 are rotatably connected to a first support plate 25, which is fixedly connected to the base 1. One end of one of the transmission rollers 18 is fixedly connected to the output end of a third motor 26, and the third motor 26 is fixedly connected to the first support plate 25. The third motor 26 acts as a drive source to drive the transmission roller 18 to rotate, and the transmission roller 18 drives the conveyor belt 17 to move.

[0047] In one embodiment of this utility model, a smooth support plate 27 is provided on the inner side of the conveyor belt 17. The upper end surface of the smooth support plate 27 is in contact with the conveyor belt 17. Second support plates 28 are fixedly connected to both sides of the smooth support plate 27 and are fixedly connected to the base 1. The smooth support plate 27 is used to support the upper end of the conveyor belt 17 and prevent the conveyor belt 17 from collapsing due to gravity.

[0048] In one embodiment of this utility model, the thickness of the protrusion 19 is greater than the thickness of the lifting plate 15. When the lifting plate 15 is located between the protrusions 19, the aluminum rod supported by the upper end of the protrusion 19 can move smoothly to the upper end of the lifting plate 15, avoiding the lifting plate 15 being too thick and blocking the movement of the aluminum rod.

[0049] In one embodiment of this utility model, a reinforcing plate 29 is fixedly connected between the lifting plate 15 and the connecting plate 8. This strengthens the connection between the lifting plate 15 and the connecting plate 8, improving their bending resistance.
