Description

Technical Field

[0001] This invention relates to the field of aluminum profile conveying equipment technology, and specifically to a bidirectional discharge mechanism for aluminum product processing. Background Technology

[0002] Roller conveyors are suitable for conveying various boxes, bags, pallets, and other packaged goods. Bulk materials, small items, or irregularly shaped items need to be placed on pallets or in turnover boxes for transport. They can transport materials with large single-item weights or withstand large impact loads. Roller lines are easy to connect and filter, and multiple roller lines can be combined with other conveyors or special machines to form complex logistics conveying systems to meet various process requirements. In the production process of recycled aluminum, they are also commonly used for conveying unloading. After scrap aluminum is recycled, melted, and recast into aluminum profiles, it is generally transported to the required location via roller conveyors. Then, long aluminum profiles are unloaded onto the ground or receiving rack using a unloading device.

[0003] Existing roller conveyors generally require a feeding device to feed long profiles unidirectionally from one side. If bidirectional feeding from both sides is desired depending on the type of aluminum profile, a feeding device is usually installed on the other side of the frame, which increases costs.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to design a mechanism that can bidirectionally unload long profiles on a roller conveyor, in order to overcome the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bidirectional feeding mechanism for aluminum product processing, used for bidirectional conveying and feeding of long profiles, comprising a frame, on which multiple rollers are rotatably mounted, and within the frame, multiple feeding rods are provided, with a first connecting rod and a second connecting rod rotatably mounted at the bottom of each feeding rod, and a first driving member and a second driving member rotatably mounted at the ends of the first and second connecting rods, respectively, with a positioning rod rotatably mounted in the middle of each of the first and second driving members and fixedly connected to the inner wall of the frame, wherein when the first connecting rod rotates on the first driving member, the angle between it and the first driving member is at most 180°, and when the second connecting rod rotates on the second driving member, the angle between it and the second driving member is at most 180°;

[0007] When the first and second drive components rotate to a position perpendicular to the ground, the feed rod lifts the long profile off the roller. When the first drive component rotates in the opposite direction, the second drive component continues to rotate in the forward direction, causing the feed rod to move horizontally while tilting towards the second drive component, so that the end of the feed rod extends out of the frame and slides the long profile laterally to one side of the frame.

[0008] Preferably, the first driving member includes a first driving rod rotatably connected to the positioning rod, and a first rectangular groove formed at the end of the first driving rod; the second driving member includes a second driving rod rotatably connected to the positioning rod, and a second rectangular groove formed at the end of the first driving rod.

[0009] Preferably, the end of the first connecting rod is located in the first rectangular groove and is rotatably connected to the first driving rod, and the end of the second connecting rod is located in the second rectangular groove and is rotatably connected to the second driving rod.

[0010] Preferably, the ends of the first connecting rod and the second connecting rod have rounded corners. When the first connecting rod and the first driving rod are parallel, the side wall of the first connecting rod fits against the inner wall of the first driving rod in the first rectangular groove. When the second connecting rod and the second driving rod are parallel, the side wall of the second connecting rod fits against the inner wall of the second driving rod in the second rectangular groove.

[0011] Preferably, a first shaft is connected through and fixedly connected to the end of the first connecting rod. A first gear is fixedly installed at one end of the first shaft, and a first positioning piece is rotatably installed at the other end and fixedly connected to the bottom surface of the feeding rod. A first rack is meshed on one side of the first gear, and a first guide strip is fixedly installed on one side of the first rack. A first guide hole is vertically passed through the feeding rod for the first rack and the first guide strip to slide.

[0012] Preferably, a second shaft is connected to the end of the second connecting rod through and fixedly connected to it. A second gear is fixedly installed at one end of the second shaft, and a second positioning piece is rotatably installed at the other end and fixedly connected to the bottom surface of the feeding rod. A second rack is meshed on one side of the second gear, and a second guide strip is fixedly installed on one side of the second rack. A second guide hole is vertically passed through the feeding rod for sliding installation of the second rack and the second guide strip. The first shaft and the second shaft are symmetrically distributed at the bottom of the feeding rod.

[0013] Preferably, the distance between the first guide strip and the second guide strip is less than the distance between the first rack and the second rack.

[0014] Preferably, a first connecting shaft is fixedly installed at the ends of the first driving components below the plurality of feeding rods, and a second connecting shaft is fixedly installed at the ends of the second driving components below the plurality of feeding rods.

[0015] Preferably, a first telescopic module and a second telescopic module are rotatably mounted on the first connecting shaft and the second connecting shaft, respectively, and positioning components that are fixedly installed in the frame are rotatably mounted at the tail of the first telescopic module and the second telescopic module.

[0016] Preferably, the connection point between the feeding rod and the first connecting rod is located directly above the connection point between the first driving member and the positioning rod, and the connection point between the feeding rod and the second connecting rod is located directly above the connection point between the second driving member and the positioning rod. The distance between the connection point between the first driving member and the positioning rod and the connection point between the second driving member and the positioning rod is greater than the distance between the two positioning members.

[0017] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0018] 1. The present invention can drive the first connecting rod, the second connecting rod, the first driving component and the second driving component to control the unloading rod to first rise vertically, then move horizontally and slightly lower to extend out of the frame, and finally tilt to slide the long profile to one side of the frame for unloading. The reverse operation can slide another type of long profile to the other side of the frame for unloading.

[0019] 2. Before the long profile slides down for feeding, the present invention will use the first guide bar and the second guide bar to prevent the long profile from sliding down, so that the long profile will automatically keep horizontal with the frame. Then, after the feeding bar is tilted at a certain angle, the long profile will slide down for feeding, avoiding the situation where the end contacts first, and promoting the long profile to contact the ground or the receiving rack line or surface contact, reducing the damage caused by collision.

[0020] 3. Meanwhile, the roller conveyor in this invention adopts double-sided feeding instead of tail feeding, which reduces the occupied area and eliminates the need to reserve a long feeding area at the tail of the roller conveyor, making it suitable for feeding long aluminum profiles.

[0031] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] This invention provides, for example Figure 1-7The illustrated bidirectional feeding mechanism for aluminum product processing is mainly used for bidirectional conveying and feeding of long aluminum profiles. It includes a frame 2 and rollers 3 as in the prior art. The rollers 3 are rotatably mounted on the frame 2 at equal intervals. A feeding rod 4 is provided between the rollers 3. A first positioning plate 12 and a second positioning plate 18 are fixedly mounted at the bottom of the feeding rod 4. A first shaft 10 is rotatably mounted inside the first positioning plate 12. A first gear 11 is fixedly mounted at the end of the first shaft 10. A first rack 13 meshes with one side of the first gear 11. A first guide strip 14 is fixedly mounted on one side of the first rack 13. A first guide hole 15 vertically penetrates the feeding rod 4, restricting the vertical sliding of the first rack 13 and the first guide strip 14. A first connecting rod 5 is fixedly mounted in the middle of the first shaft 10. A second shaft is rotatably mounted inside the second positioning plate 18. 16. A second gear 17 is fixedly installed at the end of the second shaft 16. A second rack 19 meshes with one side of the second gear 17. A second guide bar 20 is fixedly installed on one side of the second rack 19. A second guide hole 21 is vertically inserted through the feed rod 4 to restrict the vertical sliding of the second rack 19 and the second guide bar 20. A second connecting rod 6 is fixedly installed in the middle of the second shaft 16. At the same time, the distance between the first guide bar 14 and the second guide bar 20 is smaller than the distance between the first rack 13 and the second rack 19, so that when the aluminum profile slides on the feed rod 4, it will directly contact the first guide bar 14 or the second guide bar 20, avoiding contact with the teeth of the first rack 13 or the second rack 19, thereby affecting the vertical sliding of the first rack 13 or the second rack 19 in the first guide hole 15 or the second guide hole 21.

[0034] A first driving member 7, consisting of a first driving rod 701 and a first rectangular groove 702, is provided at the end of the first connecting rod 5. The end of the first connecting rod 5 is located in the middle of the first rectangular groove 702 and is rotatably connected to the first driving rod 701. One end of the first connecting rod 5 located in the first rectangular groove 702 has a rounded corner. When the first connecting rod 5 is parallel to the first driving rod 701, the side wall of the first connecting rod 5 is located in the first rectangular groove 702 and fits against the first driving rod 701. A second driving member 8, consisting of a second driving rod 801 and a second rectangular groove 802, is provided at the end of the second connecting rod 6. The end of the second connecting rod 6 is located in the middle of the second rectangular groove 802 and is rotatably connected to the second driving rod 801. One end of the second connecting rod 6 located in the second rectangular groove 802 has a rounded corner. When the second connecting rod 6 is parallel to the second driving rod 801, the side wall of the second connecting rod 6 is located in the second rectangular groove 802 and fits against the second driving rod 801.

[0035] The first drive rod 701 and the second drive rod 801 are both rotatably mounted with positioning rods 9 fixedly installed on the inner wall of the frame 2. The ends of multiple first drive rods 701 are fixedly mounted with a first connecting shaft 22. A first telescopic module 24 is rotatably mounted on the first connecting shaft 22. The ends of multiple second drive rods 801 are fixedly mounted with a second connecting shaft 23. A second telescopic module 25 is rotatably mounted on the second connecting shaft 23. The tails of the first telescopic module 24 and the second telescopic module 25 are both rotatably mounted with positioning parts 26 fixedly installed inside the frame 2. The first telescopic module 24 and the second telescopic module 25 can be electric telescopic rods or products with adjustable output shaft lengths, such as hydraulic cylinders. In the initial state, the first telescopic module 24 and the second telescopic module 25 are in an upside-down "V" shape. The connection between the first drive rod 701 and the positioning rod 9 is located directly below the first shaft 10, and the connection between the second drive rod 801 and the positioning rod 9 is located directly below the second shaft 16.

[0036] Workflow: In the initial state, such as Figure 3 As shown, the output shafts of the first telescopic module 24 and the second telescopic module 25 are extended to their maximum length. At this time, the unloading rod 4 is located below the roller 3 and does not contact the bottom surface of the long profile 1. When the long profile 1 stops being conveyed on the roller 3 and needs to be unloaded, the output shafts of the first telescopic module 24 and the second telescopic module 25 are shortened. At this time, the first drive rod 701 rotates counterclockwise and the second drive rod 801 rotates clockwise, thereby driving the first connecting rod 5 to rotate clockwise and the second connecting rod 6 to rotate counterclockwise. This causes the unloading rod 4 to rise, lifting the long profile 1 from the roller. When the first connecting rod 5 is lifted, it also drives the first shaft 10 to rotate. The first shaft 10 drives the first gear 11 to rotate, and the first gear 11 drives the rack to slide upward in the guide hole. When the second connecting rod 6 rotates, it drives the second shaft 16 to rotate, and the second shaft 16 drives the second gear 17 to rotate. The second gear 17 drives the second rack 19 to rise in the guide hole. When the first connecting rod 5, the second connecting rod 6, the first drive rod 701, and the second drive rod 801 are perpendicular to the ground, the output shaft of the first telescopic module 24 stops shortening, forming... Figure 5 As shown in the diagram; at this time, the output shaft of the first telescopic module 24 extends, while the output shaft of the second telescopic module 25 continues to shorten. The shortening of the output shaft of the second telescopic module 25 will continue to drive the second drive rod 801 to rotate clockwise. The second drive rod 801 drives the second connecting rod 6 to rotate around the connection between the second drive rod 801 and the positioning rod 9 through the second rectangular groove 802. The second connecting rod 6 pulls the feeding rod 4, and the feeding rod 4 pulls the first connecting rod 5. In conjunction with the extension of the output shaft of the first telescopic module 24, the first connecting rod 5 and the first drive rod 701 rotate in a straight line around the connection between the first drive rod 701 and the positioning rod 9, remaining parallel to the second drive rod 801. This forms a rectangular to rhomboid change pattern when the crank and the rocker arm rotate synchronously with the same length in a four-bar linkage mechanism, forming a pattern as shown in the diagram. Figure 6 As shown, the unloading rod 4 moves horizontally towards the second drive rod 801 while its height decreases; then, the output shaft of the second telescopic module 25 stops shortening, while the output shaft of the first telescopic module 24 continues to extend. Due to the weight of the long profile 1, a downward force is exerted on the unloading rod 4. The second connecting rod 6 rotates around the point where the second drive rod 801 and the second connecting rod 6 rotate, while the first connecting rod 5 and the first drive rod 701 continue to rotate in a straight line, causing the unloading rod 4 to continue moving horizontally towards the second drive rod 801. 01. The long profile 1 tilts downwards on one side, sliding towards the second drive rod 801 until it contacts the second guide bar 20 and is restricted from moving. This keeps the long profile 1 parallel to the frame 2, eliminating problems caused by skewed feeding and preventing the end from hitting the ground first when sliding off the unloading rod 4. As the angle between the second connecting rod 6 and the second drive rod 801 decreases, the second guide bar retracts back into the second guide hole 21, no longer obstructing the long profile 1. The long profile 1 slides from the unloading rod 4 towards the frame 2, completing the lateral unloading process, forming a shape like... Figure 7 As shown in the diagram; by reversing the above transmission, the feeding rod 4 can be reset. Similarly, the long profile 1 can be fed to the side of the frame 2 closer to the first drive rod 701, realizing the function of feeding two different profiles from both sides of the same roller 3 conveyor.

[0037] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative.
