Abstract

This invention discloses a waste metal recycling and sorting device with a crushing structure, relating to the field of waste metal recycling technology. The invention includes a feeding frame, with a crushing component at the bottom for crushing waste metal. At the bottom of the crushing component is a metal sorting machine body for sorting the crushed waste metal. A conveying component for transporting the waste metal is located on the inner wall of the feeding frame, and a separation device is located at the bottom of the feeding frame.

Description

Technical Field

[0001] This invention relates to the field of waste metal recycling technology, specifically to a waste metal recycling and sorting device with a crushing structure. Background Technology

[0002] Waste metal recycling and sorting equipment with a crushing structure uses a powerful crushing system to break waste metal materials into small pieces, facilitating subsequent sorting and processing. The equipment is usually equipped with an automated sorting system that can classify according to metal type (such as iron, aluminum, copper, etc.), improving recycling efficiency. Its crushing structure can effectively reduce the mixing between metals, ensuring the purity of the recycled metals. It also has strong durability and low energy consumption characteristics, making it suitable for the recycling and reuse of waste metals.

[0003] Chinese patent CN221934977U discloses a waste metal recycling and sorting device with a crushing structure, including a support frame. A waste metal recycling and sorting box is installed at the top of the support frame, and a sorting box is installed on one side of the waste metal recycling and sorting box. A feeding funnel is installed at the top of the sorting box. This patent uses a scraper to scrape off the waste metal objects adhering to the magnetic adsorption roller and scrape them into the waste metal recycling and sorting box. At this time, the first motor is started to drive the rotating shaft and the crushing blades on both sides to rotate to crush the waste metal objects. At the same time, the crushing blades also drive the second bevel gear to rotate, and under the action of gear meshing, the cleaning roller is further driven to rotate. This can realize the work of crushing and cleaning at the same time, which not only improves the work efficiency and quality, but also provides a pretreatment effect for subsequent processing.

[0004] However, current sorting equipment has the following problems: when small scrap metals (such as bolts, nuts, etc.) that need to be sorted are wrapped in plastic bags, the small scrap metals (such as bolts, nuts, etc.) will cause the plastic bags to be crushed along with them, which makes separation more difficult and results in low purity of the recycled materials. Therefore, we propose a scrap metal recycling and sorting equipment with a crushing structure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a waste metal recycling and sorting device with a crushing structure, which solves the problems mentioned in the background section.

[0010] According to the above technical solution, a winding device is provided on the side of the feeding frame. The winding device includes four spiral frames, the sides of which are fixed to the side of the feeding frame. Corresponding pairs of the four spiral frames are set as a group. A movable block is slidably installed on the inner wall of each of the four spiral frames. A spring is provided between each of the four movable blocks and the four spiral frames. A Z-shaped rod is fixed on the side of each of the four movable blocks. The ends of two Z-shaped rods away from their corresponding movable blocks are respectively fixed to the outer wall of two L-shaped blocks. The ends of the other two Z-shaped rods away from their corresponding movable blocks are respectively fixed to the outer wall of two L-shaped blocks. Eight spiral frames are fixed on the outer wall of the feeding frame. Support blocks are slidably installed on the inner wall of the four spiral frames on the same side. Hollow blocks are slidably installed on the inner wall of the four spiral frames on the other side. Each spaced support block is connected by a U-shaped frame. The hollow blocks are interconnected, with each spaced hollow block connected by a U-shaped frame. Each of the four movable blocks has an L-shaped plate fixed to its top. Two L-shaped plates on the same side, away from the movable block, are fixed to the sides of two support blocks. The other two L-shaped plates on the same side, away from the movable block, are fixed to the sides of two hollow blocks. Motors are fixed to the sides of all four support blocks. Circular posts are fixed to the output shafts of all four motors. Hollow retaining rings are inserted into the outer walls of the circular posts. Multiple long grooves are formed on the outer walls of the hollow retaining rings. Adhesive plates are slidably installed on the inner walls of the long grooves. A spring is placed between the adhesive plates and the hollow retaining rings. A pull bracket is fixed to the side of the hollow retaining rings. A ring is rotatably installed on the inner wall of each hollow block. Multiple triangular blocks are fixed to the side of the ring, and the sides of the triangular blocks are slidably installed on the inner walls of the long grooves.

[0011] According to the above technical solution, the adhesive plate is located on the displacement trajectory of the inclined plane of the triangular block.

[0012] According to the above technical solution, a collecting device is provided at the top of the feeding frame. The collecting device includes a fixed positioning block. The bottom of the positioning block is fixed to the top of the feeding frame. A U-shaped collecting block is fixedly and slidably installed on the top of the feeding frame. Multiple springs are provided between the U-shaped collecting block and the positioning block. A trapezoidal block is fixed to the side of the U-shaped collecting block.

[0013] According to the above technical solution, the inclined surface of the trapezoidal block is located on the displacement trajectory of the hollow block.

[0014] This invention provides a waste metal recycling and sorting device with a crushing structure. It has the following beneficial effects:

[0015] (1) Through the setting of the separation device, with the cooperation of the fixed block, motor 2, bidirectional threaded rod, threaded sleeve, L-shaped block 1, sawtooth plate 1, bidirectional telescopic rod, slider, L-shaped block 2, and sawtooth plate 2, the back-and-forth movement of sawtooth plate 2 and sawtooth plate 1 can tear the plastic bag containing small scrap metal at the same time, thereby avoiding the small scrap metal from being crushed along with the plastic bag, which would make separation more difficult and result in low purity of the recycled material; at the same time, with the cooperation of inclined plate, sawtooth plate 1, and sawtooth plate 2, the back-and-forth movement of sawtooth plate 2 and sawtooth plate 1 will drive the inclined plate to move. When the inclined plate moves, its inclined surface will form a wedge and lifting action, thereby conveying the small scrap metal and avoiding the small scrap metal from getting stuck in the tooth gap, causing the small scrap metal to stay at the sawtooth plate 2 and sawtooth plate 1, forming an accumulation, which would affect the subsequent material passage.

[0016] (2) Through the setting of the winding device, the present invention, with the cooperation of the first circular frame, the moving block, the Z-shaped rod, the L-shaped plate, the support block, the hollow block, the second circular frame, the third motor, the circular insert, the hollow retaining ring, and the adhesive plate, will wrap the torn plastic bag, thereby avoiding the problem that the torn but not removed plastic strips will be wrapped into a ball again or mixed with the subsequent metal to form a larger blockage. At the same time, it ensures that the boundary between small scrap metal and plastic is clearer, the sorting accuracy and efficiency are significantly improved, and the purity and value of the final recycled metal are higher. Meanwhile, the other part of the adhesive plate will also be driven by the output shaft of the corresponding third motor to rotate the circular insert, so that the small plastic fragments torn off by the first or second sawtooth plate can be adhered, thereby avoiding the problem that the small plastic fragments are carried into the crushing component.

[0017] (3) In this invention, when the adhesive plate moves toward the inner wall of the hollow retaining ring, the adhesive plate will no longer stick to the plastic strip. At the same time, when the adhesive plate and the hollow retaining ring are moving, the triangular block will clean off the small plastic blocks on the surface of the adhesive plate, thereby avoiding the problem that the adhesive plate is covered with small plastic blocks and plastic strips, which would make the adhesive plate unusable.

[0018] (4) With the collection device, the U-shaped collection block, spring three, trapezoidal block, adhesive plate and hollow retaining ring are combined. When the hollow block moves above the trapezoidal block, spring three will use its own elasticity to drive the U-shaped collection block and trapezoidal block to reset, so that the U-shaped collection block is located below the adhesive plate and hollow retaining ring. This allows small plastic blocks and plastic strips to fall into the U-shaped collection block, thus avoiding the problem of small plastic blocks and plastic strips falling back onto the belt body.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figure 1 - Figure 11 One embodiment of the present invention is as follows: a waste metal recycling and sorting device with a crushing structure, including a feeding frame 1, a crushing component 2 for crushing waste metal is provided at the bottom of the feeding frame 1, a metal sorting machine body 3 for sorting the crushed waste metal is provided at the bottom of the crushing component 2, a conveying component 4 for conveying waste metal is provided on the inner wall of the feeding frame 1, a separation device 5 is provided at the bottom of the feeding frame 1, the separation device 5 includes a fixing block 51, the top of the fixing block 51 is fixed to the bottom of the feeding frame 1, a second motor 52 is fixed to the side of the fixing block 51, a bidirectional threaded rod 53 is fixed to the output shaft of the second motor 52, two threaded sleeves 54 are threadedly connected to the circumferential surfaces of the bidirectional threaded rod 53 with opposite thread directions, an L-shaped block 55 is fixed to the side of each of the two threaded sleeves 54, a serrated plate 56 is fixed to the top of the L-shaped block 55, and two bidirectional telescopic rods 57 are rotatably installed at the bottom of the feeding frame 1 via two long rods. Two sliders 58 are slidably installed at the bottom of the feed frame 1. One telescopic end of the bidirectional telescopic rod 57 is rotatably installed at the bottom of the slider 58, and the other retracted end of the bidirectional telescopic rod 57 is rotatably installed at the bottom of the threaded sleeve 54. An L-shaped block 59 is fixed to the side of the slider 58, and a serrated plate 510 is fixed to the top of the L-shaped block 59. The transmission assembly 4 includes two pulleys 41, both of which are rotatably installed on the inner wall of the feed frame 1. A belt body 42 is connected between the two pulleys 41. One of the pulleys 41 is driven by a motor 43, which is fixed to the side of the feed frame 1. With the above structure, the back-and-forth movement of the serrated plate 510 and the serrated plate 56 can tear the plastic bag containing small scrap metal at the same time, thereby avoiding the small scrap metal from pulling the plastic bag to be crushed together. Furthermore, after crushing, the small scrap metal and plastic bag fragments will stick together, making separation more difficult and resulting in low purity of the recycled material.

[0033] Both the second sawtooth plate 510 and the first sawtooth plate 56 have inclined plates 511 fixed to their sides. The second sawtooth plate 510 and the first sawtooth plate 56 are both slidably installed through and on the side of the feed frame 1. The second sawtooth plate 510 and the first sawtooth plate 56 are staggered. With the above structure, the back-and-forth movement of the second sawtooth plate 510 and the first sawtooth plate 56 will drive the inclined plates 511 to move. When the inclined plates 511 move, their inclined surfaces will form a wedge-in and lifting action, thereby conveying small scrap metals and preventing small scrap metals from getting stuck in the tooth gaps, causing small scrap metals to stay at the second sawtooth plate 510 and the first sawtooth plate 56, forming an accumulation and affecting the subsequent material passage.

[0034] A winding device 6 is provided on the side of the feed frame 1. The winding device 6 includes four loop frames 61. The sides of the four loop frames 61 are all fixed to the side of the feed frame 1. Corresponding pairs of the four loop frames 61 are set as a group. A moving block 62 is slidably installed on the inner wall of each of the four loop frames 61. A spring is provided between each of the four moving blocks 62 and the four loop frames 61. A Z-shaped rod 63 is fixed on the side of each of the four moving blocks 62. The ends of two Z-shaped rods 63 away from their corresponding moving blocks 62 are respectively fixed to the outer walls of two L-shaped blocks 59. The other two Z-shaped rods 63 are away from their corresponding moving blocks. One end of 62 is fixed to the outer wall of two L-shaped blocks 55. Eight loop frames 66 are fixed to the outer wall of the feed frame 1. Support blocks 65 are slidably installed on the inner walls of four loop frames 66 on the same side. Hollow blocks 6501 are slidably installed on the inner walls of four loop frames 66 on the other side. Each spaced support block 65 is connected to each other by a U-shaped frame 615. Each spaced hollow block 6501 is connected to each other by a U-shaped frame 615. An L-shaped plate 64 is fixed to the top of each of the four moving blocks 62. The side of the two L-shaped plates 64 on the same side away from the moving block 62 is fixed to the two support blocks 65 respectively. On the other side, two L-shaped plates 64 on the same side, away from the moving block 62, are respectively fixed to the sides of two hollow blocks 6501. Motors 67 are fixed to the sides of all four support blocks 65. Circular inserts 68 are fixed to the output shafts of all four motors 67. Hollow retaining rings 69 are inserted into the outer walls of the circular inserts 68. Multiple long grooves are formed on the outer walls of the hollow retaining rings 69. Adhesive plates 610 are slidably installed on the inner walls of the multiple long grooves. Springs 611 are provided between the adhesive plates 610 and the hollow retaining rings 69. A pull bracket 612 is fixed to the side of the hollow retaining rings 69. The inner walls of the hollow blocks 6501 rotate. A circular ring 613 is installed, and multiple triangular blocks 614 are fixed to the side of the circular ring 613. The sides of the triangular blocks 614 are slidably installed on the inner wall of the long groove. The adhesive plate 610 is located on the displacement trajectory of the inclined surface of the triangular block 614. With the above structure, the adhesive plate 610 will wrap the torn plastic bag, thereby avoiding the problem that the torn but not removed plastic strips will be tangled again or mixed with subsequent metals to form larger blockages. At the same time, it ensures that the boundary between small scrap metals and plastics is clearer, the sorting accuracy and efficiency are significantly improved, and the purity and value of the recycled metal are higher.

[0035] In operation, the small scrap metal to be crushed, sorted, and recycled is poured into the feed frame 1. Then, motor 1 (43) is started. The output shaft of motor 1 (43) will cause one of the pulleys 41 to rotate. The rotation of this pulley 41 will drive the other pulley 41 to rotate through the belt body 42, thereby transporting the small scrap metal. Before starting motor 1 (43), motor 2 (52) is started first. The output shaft of motor 2 (52) will cause the bidirectional threaded rod 53 to rotate. The rotation of the bidirectional threaded rod 53 will cause the two threaded sleeves 54 to rotate. Moving back and forth in opposite and opposite directions, the back-and-forth movement of the two threaded sleeves 54 causes their respective L-shaped blocks 55 to move back and forth, which in turn causes the serrated plate 56 to move back and forth. Simultaneously, the back-and-forth movement of the two threaded sleeves 54, through their respective connected bidirectional telescopic rods 57, causes the two sliders 58 to move back and forth, thus causing the two sliders 58 to move out of alignment with the two threaded sleeves 54. The movement of the two sliders 58 then causes their respective L-shaped blocks 59 to move back and forth. The back-and-forth movement of the saw blade 510 causes it to move back and forth. Therefore, saw blade 510 and saw blade 56 move back and forth in a staggered manner. This back-and-forth movement of saw blade 510 and saw blade 56 can tear the plastic bag containing the small scrap metal at the same time, thus preventing the small scrap metal from pulling the plastic bag and causing it to break along with it. Furthermore, the broken scrap metal and plastic bag fragments would stick together, making separation more difficult and resulting in low purity of the recycled material. Finally, the small scrap metal will pass through the conveyor belt body 42. The material is transferred to the crushing component 2 for crushing, and then enters the metal sorting machine body 3 for sorting and recycling. The back-and-forth movement of the second sawtooth plate 510 and the first sawtooth plate 56 will drive the inclined plate 511 to move. When the inclined plate 511 moves, its inclined surface will form a wedge and lift action, thereby conveying small scrap metals and avoiding small scrap metals getting stuck in the tooth gaps, causing small scrap metals to stay at the second sawtooth plate 510 and the first sawtooth plate 56, forming an accumulation and affecting the subsequent material passage.

[0036] Simultaneously with starting motor 2 52, motor 3 67 is also started. The output shaft of motor 3 67 causes the circular insert 68 to rotate. The rotation of the circular insert 68 drives the hollow retaining ring 69 to rotate, which in turn drives the adhesive plate 610 to rotate. The rotation of the hollow retaining ring 69 also drives the triangular block 614 to rotate, which in turn drives the circular ring 613 to rotate on the inner wall of the hollow block 6501. When L-shaped block 1 55 moves the serrated plate 1 56 into the feed frame 1, L-shaped block 2 59 moves the serrated plate 2 510 towards the outer wall of the feed frame 1. Therefore, the movement of L-shaped block 1 55 pushes the moving block 62 through the Z-shaped rod 63. The L-shaped block 59 moves downward along the inner wall of the first ring 61, compressing the corresponding spring. The L-shaped block 59, via the Z-shaped rod 63, drives the moving block 62 upward along the inner wall of the first ring 61. The corresponding spring, through its own elasticity, facilitates the upward movement of the moving block 62. When the moving block 62, corresponding to the L-shaped block 55, moves downward, it causes the L-shaped plate 64 to move. The movement of the L-shaped plate 64 causes the support block 65 to move downward along the inner wall of the second ring 66. The movement of the support block 65 causes the circular insert 68, hollow retaining ring 69, adhesive plate 610, ring 613, triangular block 614, and hollow block 6501 to move downward, thereby causing the hollow retaining ring 69... The adhesive plate 610 moves above the toothed plate 56. Simultaneously, the hollow retaining ring 69 rotates the adhesive plate 610, causing it to wrap around the torn plastic bag. This prevents shredded but not removed plastic strips from tangling again or mixing with subsequent metals to form larger blockages. It also ensures a clearer boundary between small scrap metals and plastics, significantly improving sorting accuracy and efficiency, resulting in higher purity and value of the recycled metal. Meanwhile, the moving block 62, corresponding to the L-shaped block 59, moves in the same direction as described above, positioning the circular insert 68 corresponding to the L-shaped block 59 above the feed frame 1. Each time the support block 65 and the hollow block 6501 move downwards, they... The support block 65 and hollow block 6501 connected by the U-shaped frame 615 move downwards synchronously. Therefore, the downward movement of the support block 65 and hollow block 6501 will drive the connected circular insert 68, hollow retaining ring 69, adhesive plate 610, ring 613, triangular block 614, and motor 67 to move downwards. This will move the hollow retaining ring 69 and adhesive plate 610 to the top of the belt body 42. The adhesive plate 610 will also rotate due to the rotation of the circular insert 68 driven by the output shaft of the corresponding motor 67. Therefore, it can adhere the small plastic fragments torn off by the toothed plate 56 or the toothed plate 510, thereby preventing these small plastic fragments from being carried into the crushing component 2.

[0037] When the hollow retaining ring 69 and the adhesive plate 610 move above the feed frame 1, the operator pulls the pull bracket 612. The pull bracket 612 will move the hollow retaining ring 69 and the adhesive plate 610 towards the triangular block 614. Therefore, the inclined surface of the triangular block 614 will squeeze the adhesive plate 610 against the inner wall of the hollow retaining ring 69. The adhesive plate 610 will compress the spring 611 when it is squeezed. Since some plastic strips are wrapped around the outer wall of the adhesive plate 610 and the hollow retaining ring 69, the adhesive plate 610 will no longer stick to the plastic strips as it moves towards the inner wall of the hollow retaining ring 69. At the same time, as the adhesive plate 610 and the hollow retaining ring 69 move, the triangular block 614 will clean off the small plastic pieces on the surface of the adhesive plate 610, thereby avoiding the problem that the adhesive plate 610 is covered with small plastic pieces and plastic strips, making the adhesive plate 610 unusable.

[0038] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, a collecting device 7 is provided on the top of the feeding frame 1. The collecting device 7 includes a fixed positioning block 71. The bottom of the positioning block 71 is fixed to the top of the feeding frame 1. A U-shaped collecting block 72 is fixedly and slidably installed on the top of the feeding frame 1. A plurality of springs 73 are provided between the U-shaped collecting block 72 and the positioning block 71. A trapezoidal block 74 is fixed on the side of the U-shaped collecting block 72. The inclined surface of the trapezoidal block 74 is located on the displacement trajectory of the hollow block 6501. With the above structure, the springs 73 will drive the U-shaped collecting block 72 and the trapezoidal block 74 to reset through their own elastic force, so that the U-shaped collecting block 72 is located below the adhesive plate 610 and the hollow retaining ring 69, so that small plastic blocks and plastic strips can fall into the U-shaped collecting block 72, thereby avoiding the problem of small plastic blocks and plastic strips falling back onto the belt body 42.

[0039] In use, when the hollow block 6501 moves upwards towards the feed frame 1, the hollow block 6501 first contacts the lower inclined surface of the trapezoidal block 74, thereby pushing the trapezoidal block 74 away from the hollow block 6501. The movement of the trapezoidal block 74 will cause the U-shaped collecting block 72 to move. The movement of the U-shaped collecting block 72 will compress the spring 3 73. When the hollow block 6501 moves above the trapezoidal block 74, the spring 3 73 will use its own elasticity to drive the U-shaped collecting block 72 and the trapezoidal block 74 to reset, so that the U-shaped collecting block 72 is located below the adhesive plate 610 and the hollow retaining ring 69, so that small plastic blocks and plastic strips can fall into the U-shaped collecting block 72, thereby avoiding the problem of small plastic blocks and plastic strips falling back onto the belt body 42.

[0040] It should be noted that when small plastic blocks and strips fall onto the surface of the circular post 68, workers can move them into the U-shaped collection block 72.

[0041] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
