Description

Technical Field

[0001] This utility model relates to the field of waste metal recycling technology, and in particular to a waste metal recycling sorting and conveying mechanism. Background Technology

[0002] The scrap metal recycling sorting and conveying mechanism is a crucial link connecting the front-end collection with the back-end crushing, packaging, or smelting processes. Its core function is to continuously transport mixed scrap metal materials of various shapes, creating favorable conditions for manual or automated sorting in the process. The conveying stability and material distribution uniformity of this mechanism directly determine the efficiency and accuracy of the sorting operation, making it one of the core pieces of equipment affecting the quality of scrap metal recycling pretreatment.

[0003] Currently, belt conveyor systems are commonly used for scrap metal recycling and sorting. There are two common implementation methods: one is to use a single long-distance belt conveyor to transport all materials from the starting point to the final sorting point; the other is to use multiple independently driven belt conveyors connected end-to-end for relay transport. The former has a simple structure but limited functionality; the latter can achieve preliminary segmentation, but has higher equipment costs and control complexity. Both methods rely on the natural state of the materials during transport, only achieving basic handling functions.

[0004] Therefore, existing conveying mechanisms have significant structural and functional defects: First, materials tend to accumulate and distribute unevenly during transport. Existing conveyor belts typically operate at a constant speed, making it easy for scrap metal to accumulate and overlap during loading and transport, resulting in lumps or clusters on the conveyor belt surface. This not only increases the difficulty of manual sorting but also severely interferes with the visual recognition and positioning of automated sorting systems, leading to sorting omissions or low efficiency. Second, the conveying mechanism only acts as a passive carrier, lacking the mechanical function to actively break up, flatten, or organize accumulated materials. Furthermore, the use of multiple independent motors for multi-stage conveying increases energy consumption and control costs. Therefore, further improvements are needed. To this end, we propose a scrap metal recycling and sorting conveying mechanism. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a waste metal recycling, sorting and conveying mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waste metal recycling sorting and conveying mechanism, comprising a first trough frame and a second trough frame, wherein the first trough frame is located obliquely above the second trough frame, a support plate is fixedly connected to the lower surface of the first trough frame on one side of the top of the second trough frame, and support legs are fixed to the lower surfaces of both the first and second trough frames, a first conveying component is rotatably connected inside the first trough frame, a second conveying component is rotatably connected inside the second trough frame, two side plates are fixed in the middle of the first trough frame, and a leveling component is rotatably connected between the two side plates, a motor for driving the first conveying component to rotate is fixed on the outer wall of the first trough frame, a uniform speed transmission component is connected between the first conveying component and the leveling component, and an acceleration transmission component is connected between the first conveying component and the second conveying component.

[0007] Furthermore, the first conveying assembly includes a first shaft and a second shaft rotatably connected to the first trough frame, the surfaces of the first shaft and the second shaft are jointly fitted with a first conveyor belt, and the first shaft is fixedly connected to the motor output end.

[0008] Furthermore, the second conveying assembly includes a third shaft and a fourth shaft rotatably connected to the second trough frame, and a second conveyor belt is sleeved on the surface of the third shaft and the fourth shaft, with one end of the second conveyor belt located below the first conveyor belt.

[0009] Furthermore, the acceleration transmission assembly includes a third sprocket, a fourth sprocket, and a second chain. The third sprocket is fixedly connected to a second shaft, and the fourth sprocket is fixedly connected to a third shaft. The second chain is sleeved on the surfaces of the third and fourth sprockets, and the third sprocket is larger than the fourth sprocket.

[0010] Furthermore, the leveling component includes a fifth shaft rotatably connected to the two side plates, and a plurality of claws are fixed on the surface of the fifth shaft. The uniform speed transmission component includes a first sprocket, a second sprocket, and a first chain. The second sprocket is fixedly connected to one end of the fifth shaft, the first sprocket is fixedly connected to one end of the first shaft, and the first chain is sleeved on the surfaces of the first sprocket and the second sprocket. The first sprocket and the second sprocket are of the same size.

[0011] Furthermore, a mounting plate is fixed to one end of the claw near the fifth axis, and the mounting plate is fixedly connected to the fifth axis by bolts.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model, by setting up an acceleration transmission component and using a single motor drive, makes the linear speed of the second conveyor belt higher than that of the first conveyor belt. When the scrap metal material is thrown from the end of the low-speed first conveyor belt to the high-speed second conveyor belt, the inertial force generated by the speed difference causes the material to undergo relative displacement and diffusion at the moment of contact, thereby effectively breaking the original accumulation state and realizing the automatic spreading and uniform distribution of the material on the conveying surface. This not only significantly improves the visibility and sortability of the material, but also creates ideal conditions for subsequent manual or automatic sorting. At the same time, the single-motor drive scheme simplifies the structure and reduces energy consumption and control costs.

[0014] 2. This utility model integrates a leveling component driven by the same motor in the first conveyor section. The motor synchronously drives a set of rotating claws through a uniform speed transmission component, causing them to operate continuously above the first conveyor belt at a rhythm matched with the belt speed. The rotating claws can actively intervene and level the clumps of scrap metal accumulated on the conveyor belt, effectively separating the sticky light and thin materials and exposing the non-metallic impurities mixed in. This online pre-processing function improves the material condition from the source, laying a solid foundation for subsequent high-efficiency and high-precision sorting operations.

Detailed Implementation

[0021] 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.

[0022] like Figures 1-3 As shown, a waste metal recycling sorting and conveying mechanism is disclosed, including a first trough frame 1 and a second trough frame 2, with the first trough frame 1 located obliquely above the second trough frame 2. A support plate 3 is fixedly connected to the lower surface of the first trough frame 1 on one side of the top of the second trough frame 2. Support legs are fixed to the lower surfaces of both the first trough frame 1 and the second trough frame 2. A first conveying component 4 is rotatably connected inside the first trough frame 1, and a second conveying component 5 is rotatably connected inside the second trough frame 2. Two side plates 101 are fixed in the middle of the first trough frame 1, and a leveling component 6 is rotatably connected between the two side plates 101. A motor 7 for driving the first conveying component 4 to rotate is fixed on the outer wall of the first trough frame 1. A uniform speed transmission component 8 is connected between the first conveying component 4 and the leveling component 6, and an acceleration transmission component 9 is connected between the first conveying component 4 and the second conveying component 5.

[0023] The first conveying assembly 4 includes a first shaft 41 and a second shaft 42 rotatably connected to the first trough frame 1. A first conveyor belt 43 is sleeved on the surface of the first shaft 41 and the second shaft 42. The first shaft 41 is fixedly connected to the output end of the motor 7.

[0024] After the motor 7 is started, the first motor 7 will drive the first shaft 41 to rotate, thereby driving the first conveyor belt 43 to rotate towards the second conveyor assembly 5. At the same time, the second shaft 42 will also rotate.

[0025] The second conveying assembly 5 includes a third shaft 51 and a fourth shaft 52 that are rotatably connected to the second trough frame 2. A second conveyor belt 53 is sleeved on the surface of the third shaft 51 and the fourth shaft 52. One end of the second conveyor belt 53 is located below the first conveyor belt 43.

[0026] The scrap metal material conveyed by the first conveyor belt 43 will fall onto the surface of the second conveyor belt 53.

[0027] The acceleration transmission assembly 9 includes a third sprocket 91, a fourth sprocket 92, and a second chain 93. The third sprocket 91 is fixedly connected to the second shaft 42, and the fourth sprocket 92 is fixedly connected to the third shaft 51. The second chain 93 is sleeved on the surfaces of the third sprocket 91 and the fourth sprocket 92. The third sprocket 91 is larger than the fourth sprocket 92.

[0028] Under the transmission action of the third sprocket 91, the fourth sprocket 92 and the second chain 93, the rotating second shaft 42 will drive the third shaft 51 to rotate, and the third shaft 51 will drive the second conveyor belt 53 to rotate. Since the acceleration transmission component 9 plays an acceleration role, the rotation speed of the second conveyor belt 53 is greater than that of the first conveyor belt 43, so that the scrap metal will scatter when it falls from the surface of the first conveyor belt 43 to the surface of the second conveyor belt 53.

[0029] The leveling component 6 includes a fifth shaft 61 rotatably connected to the two side plates 101. Multiple claws 62 are fixed on the surface of the fifth shaft 61. The uniform speed transmission component 8 includes a first sprocket 81, a second sprocket 82, and a first chain 83. The second sprocket 82 is fixedly connected to one end of the fifth shaft 61, and the first sprocket 81 is fixedly connected to one end of the first shaft 41. The first chain 83 is sleeved on the surface of the first sprocket 81 and the second sprocket 82. The first sprocket 81 and the second sprocket 82 are the same size.

[0030] While the motor 7 drives the first shaft 41 to rotate, it drives the fifth shaft 61 to rotate through the first sprocket 81, the second sprocket 82 and the first chain 83 at a constant speed. This drives the claw 62 to rotate. When the claw 62 rotates to the bottom of the fifth shaft 61, it moves in the opposite direction to the first conveyor belt 43 and smooths out the waste metal material that is piled up on the surface of the first conveyor belt 43.

[0031] A mounting plate 63 is fixed to one end of the claw 62 near the fifth shaft 61, and the mounting plate 63 is fixedly connected to the fifth shaft 61 by bolts. The claw 62 is a consumable part that comes into contact with scrap metal. When the claw 62 is severely worn, it can be disassembled and replaced.

[0032] Working principle: When the motor 7 is started, the waste metal material is poured onto the surface of the first conveyor belt 43. The motor 7 drives the first shaft 41 of the first conveying component 4 to rotate, causing the first conveyor belt 43 to move towards the second conveying component 5. At the same time, the motor 7 drives the fifth shaft 61 of the leveling component 6 to rotate at the same speed through the first sprocket 81, the first chain 83 and the second sprocket 82 of the uniform speed transmission component 8. This causes the multiple claws 62 fixed to the fifth shaft 61 to rotate accordingly. When the rotating claws 62 rotate to the area below the fifth shaft 61, their direction of movement is opposite to the running direction of the first conveyor belt 43, thereby continuously turning over and leveling the waste metal material accumulated on the surface of the first conveyor belt 43, achieving pretreatment.

[0033] The leveled material continues to be conveyed to the end of the first conveyor belt 43. The second shaft 42 of the first conveyor belt 43 transmits power to the third shaft 51 of the second conveyor assembly 5 through the third sprocket 91, the second chain 93, and the fourth sprocket 92 of the acceleration transmission assembly 9. Since the third sprocket 91 is larger than the fourth sprocket 92, this transmission is an acceleration transmission, making the linear speed of the third shaft 51 and the second conveyor belt 53 higher than that of the first conveyor belt 43. When the material falls from the low-speed first conveyor belt 43 to the high-speed second conveyor belt 53, the inertial force generated by the speed difference causes the material to diffuse and redistribute, effectively breaking the accumulation state and achieving uniform spreading of the material on the surface of the second conveyor belt 53. Finally, the uniformly dispersed material continues to be conveyed backward with the second conveyor belt 53, creating favorable conditions for subsequent sorting operations.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
