Description

Technical Field

[0001] This invention relates to the field of electronic component recycling equipment technology, and specifically to an electronic waste recycling and processing equipment. Background Technology

[0002] With the rapid development of the electronics and information industry, the product update cycle of electronic products is constantly shortening, resulting in an explosive growth in the amount of electronic waste (such as discarded mobile phones, computers, home appliances, and electronic component manufacturing waste). Electronic waste contains various high-value metal resources such as copper, aluminum, gold, and silver, as well as non-metallic components such as plastics and glass. Efficient recycling can not only reduce resource waste but also avoid environmental problems such as heavy metal pollution and soil acidification caused by indiscriminate disposal. Current technologies for recycling electronic waste first crush parts such as casings and motherboards to facilitate subsequent processing. Traditional crushing methods mostly use double-toothed roller crushers, but because crushing usually involves crushing waste of varying sizes together, the resulting waste is unevenly crushed, and the crushing equipment suffers from low crushing efficiency. Summary of the Invention

[0003] This invention provides an electronic waste recycling and processing device to solve the problem that existing crushers usually crush waste of different sizes together, resulting in uneven crushing and low crushing efficiency.

The first and second discharge areas are used to receive waste with a size smaller than or equal to a first preset value. The second discharge area is used to receive waste with a size larger than the first preset value. Waste falling into the first discharge area can directly enter the meshing end of the two crushing belts. Waste falling into the second discharge area moves synchronously with the rotation of the crushing belts. Both crushing plates are installed in the housing. Each crushing plate is parallel to a crushing belt. Each crushing plate and a crushing belt define a pre-crushing zone, which is located between the second discharge area and the meshing end of the two crushing belts. The crushing plates can move relative to the crushing belts.

[0005] Furthermore, the crushing belt includes a belt body, a first drive shaft, and a second drive shaft. Both the first and second drive shafts are mounted on the housing and are arranged along a first direction and are rotatable around their own axes. The first drive shaft is located on the side of the housing near the vertical central axis of the housing in the second direction. The second direction is horizontal and perpendicular to the first direction. The belt body is wound around the first and second drive shafts. Multiple first crushing blades are evenly distributed in the circumferential direction of the belt body. Each crushing plate is parallel to a belt body.

[0007] Furthermore, it also includes two rotating frames, which are rotatably mounted inside the housing in a first direction, and two crushing belts are rotatably mounted on the two rotating frames respectively.

[0008] Furthermore, a track groove is provided on the housing, the second drive shaft extends out of the housing through the track groove and is connected to the rotating block; a rotating groove is provided on the rotating block, the second drive shaft is rotatably installed in the rotating groove, a protrusion is provided in the circumferential direction of the second drive shaft, and a groove is provided in the rotating block that can rotate and cooperate with the protrusion, so that the rotating block and the second drive shaft can move relative to each other.

[0009] Furthermore, the guiding mechanism includes a first connecting frame, a second connecting frame, two connecting plates, and two telescopic rods. The first connecting frame is vertically positioned within the housing and located between the two crushing belts. The second connecting frame is slidably mounted on the first connecting frame in the vertical direction. The two telescopic rods are slidably mounted on both sides of the first connecting frame in the vertical direction. The two connecting plates are located on both sides of the first connecting frame, and their ends are rotatably connected to the second connecting frame and one telescopic rod, respectively. Both connecting frames have grooves along a third direction, which is the direction of the side of the crushing belt. The two crushing plates... The two crushing plates are slidably installed in two chute sections, and each crushing plate is rotatably connected to a first connecting frame and a telescopic rod at both ends. The two connecting plates and the two crushing plates form a first material dropping area, and a second material dropping area is formed between each crushing belt and the corresponding connecting plate. Multiple first material dropping ports are evenly distributed on the connecting plates, and a second material dropping port is provided on the first connecting frame. Both the first and second material dropping ports allow only waste with a size smaller than or equal to a first preset value to enter. The second material dropping port is located directly above the end of the two crushing belts that are close to each other, so that the waste can directly enter the end of the two crushing belts that are meshing.

A connecting sleeve is provided on the paddle, which is installed on the rotating sleeve and moves synchronously with and rotates relative to the rotating sleeve. A protrusion is provided inside the connecting sleeve and is installed in the threaded groove. When the second connecting frame moves in the vertical direction, the protrusion moves in the threaded groove, thereby causing the connecting sleeve to drive the paddle to swing back and forth.

[0012] Furthermore, two sealing plates are provided inside the housing, with each rotating frame abutting against one sealing plate. The sealing plates are connected to the housing by a first elastic element, which is arranged along the second direction.

[0013] Furthermore, a stop block is provided inside the housing, which is arranged along the first direction and located directly above the paddle, defining two feed ports between the stop block and the housing.

The other waste (including waste larger than or equal to the first preset value) will fall onto the crushing belts from the second discharge area. As the crushing belts rotate continuously, the waste will move towards the end where the two crushing belts are close to each other. During the movement, the waste passes through the crushing plates. When the waste passes through the crushing plates, it will be torn by the relative movement of the crushing plates and the crushing belts, achieving pre-crushing of the waste. Then, it will come to the end where the two crushing belts are close to each other for synchronous crushing with the waste smaller than or equal to the first preset value, increasing the overall crushing efficiency. Furthermore, the pre-crushing setting of the crushing plates can also improve the crushing effect of waste larger than the first preset value. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] An embodiment of an electronic waste recycling and processing device according to the present invention, such as... Figures 1 to 7 As shown.

[0020] An electronic waste recycling and processing device includes a housing 100, a guiding mechanism 200, two crushing plates 300 and two crushing belts 400.

[0021] The housing 100 has a feed inlet 101. Two crushing belts 400 are installed inside the housing 100 and can rotate around a first direction, which is horizontal. One end of the two crushing belts 400 is close to each other, and the other end is far away from each other. The ends of the two crushing belts 400 that are close to each other are engaged, and the ends of the two crushing belts 400 that are far away from each other are located on the side of the ends of the two crushing belts 400 that are close to each other that are near the feed inlet 101.

[0022] A guiding mechanism 200 is installed inside the housing 100. The guiding mechanism 200 defines a first discharge area 210 and a second discharge area 220 between the two crushing belts 400. The first discharge area 210 receives waste with a size smaller than or equal to a first preset value, while the second discharge area 220 receives waste with a size larger than the first preset value. Waste falling into the first discharge area 210 can directly enter the meshing end of the two crushing belts 400, and waste falling into the second discharge area 220 moves synchronously with the rotation of the crushing belts 400. Two crushing plates 300 are both installed inside the housing 100. Each crushing plate 300 is parallel to one crushing belt 400, and a pre-crushing zone is defined between each crushing plate 300 and one crushing belt 400. The pre-crushing zone is located between the second discharge area 220 and the meshing end of the two crushing belts 400. The crushing plates 300 are movable relative to the crushing belts 400. The housing 100 has a discharge port 102 located below the two crushing belts 400, which is used to discharge the crushed waste.

[0023] This embodiment, through the coordinated arrangement of a housing 100, a guiding mechanism 200, two crushing plates 300, and two crushing belts 400, allows waste to enter the housing 100 from the feed inlet 101. Under the action of the guiding mechanism 200, a portion of the waste with a size smaller than or equal to a first preset value can enter the first discharge area 210, while the rest of the waste (including waste with a size larger than or equal to the first preset value) will fall onto the crushing belts 400 from the second discharge area 220. As the crushing belts 400 continuously rotate, the waste will continuously move towards the end where the two crushing belts 400 are close to each other, and pass through the crushing plates 300 during the movement. When the waste passes through the crushing plates 300, it will be torn by the relative movement of the crushing plates 300 and the crushing belts 400, thus achieving pre-crushing of the waste. Afterward, it will come to the end where the two crushing belts 400 are close to each other and be crushed synchronously with the waste with a size smaller than or equal to the first preset value. By pre-crushing the waste with a size larger than the first preset value, the overall crushing efficiency can be increased, and the crushing effect of the waste with a size larger than the first preset value can also be improved.

[0024] In this embodiment, the shredding belt 400 includes a belt body 401, a first drive shaft 402, and a second drive shaft 403. Both the first drive shaft 402 and the second drive shaft 403 are mounted on the housing 100 and are both arranged along a first direction and capable of rotating around their own axes. The first drive shaft 402 is located on the side of the second drive shaft 403 near the vertical central axis of the housing 100 in the second direction. The second direction is horizontal and perpendicular to the first direction. The belt body 401 is wound around the first drive shaft 402 and the second drive shaft 403. Multiple first shredding blades 404 are evenly distributed circumferentially on the belt body 401. Each shredding plate 300 is parallel to one belt body 401, and multiple second shredding blades 301 are arranged on the side of the shredding plate 300 near the first shredding blades 404. When waste passes through the pre-shredding space, the relative movement of the first shredding blades 404 and the second shredding blades 301 can tear the waste, achieving pre-shredding.

[0025] Furthermore, a motor 103 is mounted on the housing 100, and a first drive shaft 402 is mounted on the output shaft of the motor 103 via a drive belt, rotating synchronously with the motor 103. The motors 103 correspondingly mounted on the two first drive shafts 402 rotate in opposite directions, so that the waste can be crushed when it enters the meshing end of the two crushing belts 400.

[0026] In this embodiment, an electronic waste recycling and processing device further includes a hydraulic cylinder 500 and a connecting block 501. Rotating blocks 405 are provided at both ends of the second drive shaft 403. The rotating blocks 405 are coaxially arranged with the second drive shaft 403 and can rotate relative to it. The rotating blocks 405 extend out of the housing 100. The hydraulic cylinder 500 is mounted on the housing 100 and can extend and retract in the vertical direction. The connecting block 501 is fixedly installed at the output end of the hydraulic cylinder 500. Two rotating blocks 405 correspondingly arranged on the two second drive shafts 403 are rotatably connected to the connecting block 501 through two connecting rods.

[0027] Specifically, the housing 100 has a track groove 104, and the second drive shaft 403 extends out of the housing 100 through the track groove 104 and is connected to the rotating block 405. The rotating block 405 has a rotating groove, and the second drive shaft 403 is rotatably mounted in the rotating groove. The second drive shaft 403 has a protrusion in the circumferential direction, and the rotating block 405 has a groove that can rotate and cooperate with the protrusion, so that the rotating block 405 and the second drive shaft 403 can move relative to each other.

[0028] In this embodiment, by setting up a hydraulic cylinder 500 and a connecting block 501 in cooperation, the two crushing belts 400 are arranged in a V-shape within the housing 100 by bringing one end of each other closer together and the other end further apart. During crushing, the hydraulic cylinder 500 is activated, which drives the connecting block 501 to move vertically. As the connecting block 501 moves, it drives the two rotating blocks 405 to rotate within the track groove 104 via the connecting rod. This causes the two crushing belts 400 to rotate around the first direction at the ends that are close together, changing from open to closed and then open again, and repeating this cycle. The arrangement of the crushing belts 400 increases the path of the debris and reduces the space for the debris to move after crushing when the two crushing belts 400 change from open to closed, thus preventing the debris from collapsing during the crushing process.

[0029] Furthermore, an electronic waste recycling and processing device also includes two rotating frames 502, which are rotatably mounted inside the housing 100 around a first direction, and two crushing belts 400 are respectively rotatably mounted on the two rotating frames 502. Specifically, a first drive shaft 402 and a second drive shaft 403 corresponding to each crushing belt 400 are respectively rotatably mounted at both ends of one rotating frame 502.

[0030] In this embodiment, the guiding mechanism 200 includes a first connecting frame 230, a second connecting frame 240, two connecting plates 250, and two telescopic rods 260. The first connecting frame 230 is vertically disposed within the housing 100 and located between the two crushing belts 400. The second connecting frame 240 is slidably mounted on the first connecting frame 230 in a vertical direction. The two telescopic rods 260 are slidably mounted on both sides of the first connecting frame 230 in a vertical direction. The two connecting plates 250 are located on both sides of the first connecting frame 230, and their ends are rotatably connected to the second connecting frame 240 and a telescopic rod 260, respectively. Each of the two rotating frames 502 has a sliding groove 503, which is arranged in a third direction, which is the direction of the side of the crushing belt 400. The two crushing plates 300 are slidably mounted in the two sliding grooves 503, and the two ends of each crushing plate 300 are rotatably connected to the first connecting frame 230 and a telescopic rod 260, respectively.

[0031] Two connecting plates 250 and two crushing plates 300 enclose a first material dropping area 210. A second material dropping area 220 is formed between each crushing belt 400 and the corresponding connecting plate 250. Multiple first material dropping ports 252 are evenly distributed on the connecting plate 250. A second material dropping port 231 is provided on the first connecting frame 230. Both the first material dropping port 252 and the second material dropping port 231 only allow waste with a size smaller than or equal to a first preset value to enter. The second material dropping port 231 is located directly above the end of the two crushing belts 400 that are close to each other, so that the waste can directly enter the end of the two crushing belts 400 that are meshing.

[0032] In this embodiment, by setting up a first connecting frame 230, a second connecting frame 240, two connecting plates 250, and two telescopic rods 260 in cooperation, a first dropping area 210 and a second dropping area 220 are defined between the two crushing belts 400. This allows waste with a size smaller than or equal to a first preset value to pass through the first dropping area 210, while other waste can fall into the second dropping area 220. When the two crushing belts 400 rotate around the first direction, since the crushing plates 300 are arranged parallel to the crushing belts 400, when the two crushing belts 400 rotate around the first direction and converge, the crushing belts 400 will cause the two crushing plates 300 to rotate, thereby causing the telescopic rods 260 to retract, and causing the second connecting frame 240 to move upward relative to the first connecting frame 230, so that the first dropping area 210 converges synchronously. At the same time, the crushing plate 300 will slide on the rotating frame 502 to realize the relative movement between the crushing plate 300 and the crushing belt 400. The first crushing blade 404 and the second crushing blade 301 cooperate with each other to pre-crush the waste with a size larger than the first preset value.

[0033] Furthermore, multiple guide plates 251 are evenly distributed on both connecting plates 250. By setting multiple guide plates 251, as the rhomboid first material dropping area 210 formed by the two connecting plates 250 and the two crushing plates 300 continuously deforms, the guide plates 251 on the connecting plates 250 guide the waste in the second material dropping area 220, thereby reducing the resistance caused by the waste when the two crushing belts 400 approach each other.

[0034] Furthermore, two sealing plates 105 are provided inside the housing 100, and each rotating frame 502 abuts against one sealing plate 105. The sealing plate 105 is connected to the housing 100 through a first elastic member 106, which is arranged along the second direction.

[0035] By setting two sealing plates 105, when the two crushing belts 400 rotate around the first direction, they will drive the rotating frame 502 to rotate synchronously, moving towards or away from the sealing plates 105. When the rotating frame 502 moves towards the sealing plates 105, it will compress the first elastic element 106. When the rotating frame 502 moves away from the sealing plates 105, the first elastic element 106 will reset, ensuring that the sealing plates 105 are always in contact with the rotating frame 502. This ensures that when the two crushing belts 400 rotate around the first direction, the waste can fall into the second discharge area 220.

[0036] In this embodiment, an electronic waste recycling and processing device further includes multiple feeding mechanisms 600. These feeding mechanisms 600 are sequentially arranged along a first direction on a second connecting frame 240. Each feeding mechanism 600 includes a connecting post 610 and a feeding plate 620. The connecting post 610 is arranged vertically and fixed to a first connecting frame 230. A rotating sleeve 241 is provided on the second connecting frame 240, through which the connecting post 610 passes. A threaded groove 611, which is a zigzag shape, is provided on the connecting plate 620. The connecting sleeve 621 is mounted on the rotating sleeve 241, moves synchronously with the rotating sleeve 241, and rotates relative to it. A protrusion is provided inside the connecting sleeve 621, which is installed within the threaded groove 611. When the second connecting frame 240 moves vertically, the protrusion moves within the threaded groove 611, thereby causing the connecting sleeve 621 to drive the feeding plate 620 to reciprocate.

[0037] In this embodiment, by setting up a feeding mechanism 600, when the two crushing belts 400 rotate around the first direction respectively, the second connecting frame 240 moves in the vertical direction, which will drive the protrusion to move in the threaded groove 611, thereby causing the connecting sleeve 621 to drive the feeding plate 620 to swing back and forth, so that the waste is evenly distributed in the second dropping area 220.

[0038] Furthermore, a stop 107 is provided inside the housing 100. The stop 107 is arranged along the first direction and is located directly above the paddle 620. The stop 107 and the housing 100 define two feed inlets 101. By setting the stop 107, the waste can be allowed to enter from the two feed inlets 101 respectively, preventing the waste from falling directly onto the paddle 620.

[0039] Based on the above embodiments, the specific working principle and process are as follows: In use, the motor 103 is started, which drives the two crushing belts 400 to rotate. The waste then enters the housing 100 through the feed inlet 101. After entering the housing 100, some waste smaller than or equal to a first preset value can enter the first discharge area 210 formed by the two connecting plates 250 and the two crushing plates 300 through the first discharge port 252. From the first discharge area 210, it flows downwards through the second discharge port 231 directly into the meshing end of the two crushing belts 400. Other waste (including waste larger than or equal to the first preset value) will be discharged from the second discharge port 231. The material falling area 220 falls onto the crushing belt 400. As the crushing belt 400 rotates continuously, the waste will move towards the end where the two crushing belts 400 are close to each other. During the movement, the waste passes through the crushing plate 300. When the waste passes through the crushing plate 300, it will be torn by the relative movement of the crushing plate 300 and the crushing belt 400, thus achieving pre-crushing of the waste. Then, it will come to the end where the two crushing belts 400 are close to each other and be crushed synchronously with waste with a size smaller than or equal to a first preset value. By pre-crushing waste with a size larger than the first preset value, the overall crushing efficiency can be increased, and the crushing effect of waste with a size larger than the first preset value can also be improved.

[0040] Simultaneously, the hydraulic cylinder 500 is activated, causing the connecting block 501 to move vertically. As the connecting block 501 moves, it drives the two rotating blocks 405 to rotate within the track groove 104 via the connecting rod. This causes the ends of the two crushing belts 400 that are close to each other to rotate around the first direction, changing from open to closed and then open again, in a cyclical manner. The crushing belts 400 increase the path for debris to dissipate, and when the two crushing belts 400 change from open to closed, they reduce the space for the crushed debris to move, preventing debris from scattering during the crushing process. Furthermore, as the two crushing belts 400 rotate around the first direction, the second connecting frame 240 moves vertically, causing the protrusion to move within the threaded groove 611. This, in turn, causes the connecting sleeve 621 to drive the paddle 620 to swing back and forth, ensuring that the debris is evenly distributed within the second material drop area 220.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
