Description

Technical Field

[0001] This utility model relates to the field of sorting machines, and in particular to an eddy current sorting machine. Background Technology

[0002] A sorting machine is a device used to separate different materials. It is widely used in industries such as industry, environmental protection, electronics manufacturing, and agriculture. Depending on the working principle and application scenario, sorting machines can be divided into various types, including eddy current sorting machines, gravity sorting machines, optical sorting machines, and ultrasonic sorting machines.

[0003] Eddy current separators are key equipment for efficiently separating non-ferrous metals (such as copper, aluminum, zinc, etc.). They are widely used in fields such as scrap metal recycling, electronic waste treatment, and automobile dismantling. Their core principle is to use an alternating magnetic field to induce eddy currents in conductive metals, thereby generating repulsive forces to achieve separation.

[0004] However, traditional eddy current separators may result in uneven accumulation of metals and non-metals within the collection box during screening. During the feeding process, materials may accumulate on one side of the box, requiring manual intervention. Otherwise, the accumulation may overflow the box, increasing the frequency of manual cleaning and resulting in low collection efficiency. Therefore, an eddy current separator is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a current sorting machine, which aims to improve the existing technology where, during the feeding process, materials may accumulate on one side of the box, requiring manual intervention to prevent overflow and increase the frequency of manual cleaning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an eddy current separator, comprising a conveyor frame, a connecting box fixedly connected to the left side of the conveyor frame, a baffle fixedly connected to the inner wall of the connecting box, a magnetic roller provided on the inner side of the conveyor frame, and a vibration mechanism provided on the side wall of the connecting box.

[0007] The vibration mechanism includes a pulley a, which is connected to a pulley b via a transmission belt. A rotating block is fixedly connected to the surface of the pulley b, and a contact rod is fixedly connected to the surface of the rotating block. The outer arc surface of the contact rod contacts a sliding seat. A sliding block is hinged to the end of the sliding seat away from the contact rod. A connecting block is slidably connected to the outer wall of the sliding block. Two sets of fixed blocks are slidably connected to the outer wall of the connecting block. A hinge rod is hinged to the bottom end of the outer wall of the fixed block. A connecting frame is hinged to the end of the hinge rod away from the fixed block. A base plate is fixedly connected to both sides of the connecting frame.

[0008] As a further description of the above technical solution:

[0009] The surface of the base plate is provided with an adjustable fixing component, which includes a bidirectional threaded rod. The surface of the bidirectional threaded rod is threaded with a fixing clamp, and the inner sidewall of the fixing clamp contacts a collection box.

[0010] As a further description of the above technical solution:

[0011] The rotation center shaft of the pulley b is rotatably connected to the surface of the connecting box, and the magnetic roller is fixedly connected to the rotation center shaft of the pulley a.

[0012] As a further description of the above technical solution:

[0013] The pulley b is rotatably connected to the outer surface of the top of the connecting box.

[0014] As a further description of the above technical solution:

[0015] Both sets of fixing blocks are fixedly connected to the outer surface of the connecting box, and the rotatable connection is connected to the surface of the side wall of the connecting box.

[0016] As a further description of the above technical solution:

[0017] The bottom support leg of the connecting box is provided with a sliding groove, and the outer wall of the connecting frame is slidably connected to the sliding groove of the support leg of the connecting box.

[0018] As a further description of the above technical solution:

[0019] The bidirectional threaded rod is rotatably connected to the outer sidewall.

[0020] As a further description of the above technical solution:

[0021] The inner wall of the base plate is provided with a sliding groove, and the outer wall of the fixing clamp is slidably connected to the inner wall of the sliding groove of the base plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the rotation of the magnetic roller will cause the rotating block to move the sliding seat. The sliding seat will drive the connecting block to move up and down through the sliding block, applying a pushing or pulling force to the hinge rod, causing the connecting frame to vibrate the bottom plate in the groove on the surface of the connecting box. Vibration can keep the material in the box loose, preventing non-ferrous metal particles or non-metallic debris from accumulating on one side of the box, reducing the frequency of manual cleaning, effectively solving problems such as material accumulation and adhesion, and improving collection efficiency and sorting accuracy.

[0024] 2. In this utility model, by rotating the bidirectional threaded rod, the two sets of fixing clamps can be moved closer to each other or further apart, and more precise fixing can be achieved by dynamically adapting to changes in the size, vibration amplitude and working conditions of the collection box.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3This utility model provides an embodiment of an eddy current separator, including a conveyor frame 1. The conveyor frame 1 undertakes the key functions of carrying, guiding, and transporting materials, and is the core support structure of the eddy current separator. The conveyor frame 1 is existing technology. A connecting box 4 is fixedly connected to the left side of the conveyor frame 1, and the connecting box 4 fixes the conveyor frame 1. A baffle 6 is fixedly connected to the inner wall of the connecting box 4, and the connecting box 4 supports the baffle 6. At the same time, the baffle 6 can prevent non-metals from entering the output port on the left side of the connecting box 4, ensuring the efficiency and reliability of the sorting process in the field of metal recycling. A magnetic roller 5 is provided on the inner side of the conveyor frame 1. The magnetic roller 5 interacts with the metal material by generating an alternating magnetic field to achieve the separation of metals and non-metals. This is existing technology. The magnetic roller 5 is located at the end of the conveyor frame 1 that extends into the connecting box 4. A vibration mechanism 2 is provided on the side wall of the connecting box 4.

[0036] Reference Figure 3 and Figures 6-7 The vibration mechanism 2 includes a pulley a21, which is connected to a pulley b22 via a transmission belt. Rotation of pulley a21 drives pulley b22 to rotate. Pulley b22 is rotatably connected to the outer surface of the top of the connecting box 4. The rotation axis of pulley b22 is rotatably connected to the surface of the connecting box 4, which supports pulley b22. A magnetic roller 5 is fixedly connected to the rotation axis of pulley a21. A motor is installed inside the magnetic roller 5, which drives pulley a21 to rotate around a center. A rotating block 23 is fixedly connected to the surface of pulley b22. Rotation of pulley b22 drives rotating block 23 to rotate around a center. A contact rod 211 is fixedly connected to the surface of rotating block 23. Rotation of rotating block 23 around a center causes contact rod 211 to rotate in a circle on the surface of rotating block 23. The outer arc surface of contact rod 211 contacts a sliding seat 24. The sliding seat 24 has a groove on its surface. When the contact rod 211 rotates around the center, it will slide against the inner wall of the groove of the sliding seat 24. At the same time, it will drive the sliding seat 24 to rotate around the center. The end of the sliding seat 24 away from the connecting block 26 is rotatably connected to the connecting box 4. The end of the sliding seat 24 away from the contact rod 211 is hinged to a sliding block 25. The sliding seat 24 supports the sliding block 25. The outer wall of the sliding block 25 is slidably connected to the connecting block 26. The surface of the connecting block 26 has a transverse groove. The outer wall of the sliding block 25 slides left and right in the transverse groove on the surface of the connecting block 26. When the sliding seat 24 rotates around the rotation center point, it will push the sliding block 25 to slide laterally in the transverse groove of the connecting block 26. The outer wall of the connecting block 26 is slidably connected to two sets of upper and lower fixing blocks 27. The two sets of fixing blocks 27 support the connecting block 26.

[0037] Reference Figure 3 and Figures 6-7Both sets of fixing blocks 27 are fixedly connected to the outer surface of the connecting box 4. The sliding seat 24 is rotatably connected to the surface of the side wall of the connecting box 4. The connecting box 4 fixes the sliding seat 24. A groove is provided on the support leg at the bottom of the connecting box 4. The outer wall of the connecting frame 29 is slidably connected in the groove of the support leg of the connecting box 4. The connecting box 4 supports the connecting frame 29. The bottom end of the outer wall of the connecting block 26 is hinged to a hinge rod 28. The connecting block 26 slides up and down, causing the hinge rod 28 to slide up and down. The end of the hinge rod 28 away from the fixing block 27 is hinged to the connecting frame 29. The up and down movement of the hinge rod 28 causes the connecting frame 29 to reciprocate within the groove of the support leg of the connecting box 4. Both sides of the connecting frame 29 are fixedly connected to a base plate 210. The reciprocating movement of the connecting frame 29 causes both base plates 210 to reciprocate. The surface of the base plate 210 is provided with an adjustable fixing component 3.

[0038] Reference Figures 3-5 The adjustable fixing component 3 includes a bidirectional threaded rod 33. By rotating the bidirectional threaded rod 33, the two sets of fixing clips 32 can be brought closer together or moved away from each other. The bidirectional threaded rod 33 is rotatably connected to the outer sidewall of the base plate 210. The base plate 210 supports the bidirectional threaded rod 33. The inner wall of the base plate 210 has a sliding groove. The outer wall of the fixing clip 32 is slidably connected to the inner wall of the sliding groove of the base plate 210. The sliding groove of the inner wall of the base plate 210 allows the two sets of fixing clips to move along the fixed direction on the inner wall of the sliding groove. The surface of the bidirectional threaded rod 33 is threadedly connected to the fixing clip 32. The bidirectional threaded rod 33 supports the fixing clip 32. At the same time, the bottom end of the fixing clip 32 has an internal threaded groove, which matches the forward and reverse threads on the surface of the bidirectional threaded rod 33. The fixing clip 32 contacts the surface of the external collection box. The two fixing clips 32 apply a squeezing force to both sides of the collection box to fix the collection box and prevent the position of the collection box from shifting when the base plate 210 swings back and forth.

[0039] Working principle: When using this equipment, the material to be filtered by the filter plate is conveyed to the connecting box 4 through the conveyor frame 1. Before exiting the connecting box 4, the material is affected by the magnetic force of the magnetic roller 5, which will screen the metal material and the non-metal material. The metal material will pass through the baffle 6 and enter the metal collection box due to the magnetic force, while the non-metal material will be fed down into the non-metal collection box along the conveyor frame 1. When different materials enter the collection box.

[0040] Simultaneously, the rotation of magnetic roller 5 drives pulley a21 to rotate around the center. Pulley a21, via a belt, drives pulley b22 to rotate around the center. The rotation of pulley b22 drives surface rotating block 23 to rotate around the center. The rotation of rotating block 23 drives surface contact rod 211 to rotate around the center on the surface of rotating block 23. Contact rod 211 slides on the inner wall of the guide groove of sliding seat 24, thereby driving sliding seat 24 to rotate around the center. Sliding block 25 is hinged to sliding seat 24. The reciprocating movement of sliding seat 24 drives sliding block 25 to slide back and forth in the slot of connecting block 26, simultaneously driving connecting block 26 to move against fixed block 2. The inner wall of 7 slides up and down. The sliding of the connecting block 26 will drive the hinge rod 28 at the bottom to pull inward or push outward. The reciprocating movement of the hinge rod 28 will drive the bottom connecting frame 29 to move back and forth in the sliding groove of the support foot of the connecting box 4. This allows the collection box fixed on the surface of the bottom plate 210 to swing back and forth. The shaking can keep the material in the box loose, prevent non-ferrous metal particles or non-metallic debris from clumping at the bottom of the box, and shake off the material attached to the box wall. It can also prevent broken plastic pieces from being attracted to the inner wall of the box due to static electricity, reduce the frequency of manual cleaning, effectively solve the problems of material accumulation and adhesion, and improve collection efficiency and sorting accuracy.

[0041] By rotating the bidirectional threaded rod 33, the two sets of fixing clamps 32 can be brought closer together or moved away from each other on the surface of the base plate 210. By dynamically adapting to the size of the collection box, the external collection box can be firmly installed on the surface of the base plate 210, preventing the collection box from detaching from the base plate 210 during reciprocating shaking.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
