Description

Technical Field

[0001] The invention relates to the technical field of waste plastic recycling, in particular to waste plastic recycling equipment with a metal separation function. Background Art

[0002] With the rapid development of metal-plastic composites around the world, various metal-plastic composites have been widely used. For example, plastic recycling plants are used to pre-process waste plastics from various sources, separating the metal impurities from them for subsequent processing and recycling of the plastics. Waste treatment plants, when sorting and processing urban waste, can separate waste plastics and metals from mixed waste, achieving resource recycling and reducing environmental pollution. Electronic waste treatment plants, such as circuit boards and plastic casings, contain large amounts of waste plastics and metals. This separation device can effectively separate the plastics and metals in electronic waste, allowing for the recovery and refining of metals and the recycling of plastics.

[0003] At present, the recycling of such materials is still in its infancy. Generally, incineration and chemical methods are used to recycle waste. Metals and plastics cannot be recycled at the same time. In addition, the cost is high, the recovery rate is low, and the scale is small, making it difficult to achieve industrial recycling. This not only pollutes the environment but also wastes a lot of resources. Summary of the Invention

The material guide assembly is fixedly installed on the side of the top of the frame and extends to the interior of the separation operation chamber through the material guide trough; A crushing assembly, the crushing assembly being rotatably mounted inside the separation operation chamber and being rotatably adapted to the material guide assembly; The airflow separation component is fixedly mounted on the surface of the separation operation chamber away from the material guide component, and is mounted above the magnetic strip. When separating the metal from the waste plastic, the staff first places the waste plastic inside the material guide component. The inclined material guide component transports the raw materials through the material guide trough into the separation operation chamber, so that the waste plastic is crushed by the crushing component installed in the separation operation chamber. At this time, the crushing component rotated by the motor rolls and crushes the waste plastic. The crushed plastic fragments fall to the bottom of the separation operation chamber. The airflow separation component installed in the separation operation chamber blows the plastic fragments, so that the lighter plastic particles are carried by the airflow and flow to the side of the discharge port with the airflow, while the heavier metal particles settle and adsorb on the magnetic strip, thereby completing the separation of plastic and metal in the waste plastic.

[0005] Preferably, the material guiding assembly includes a support frame, a conveying plate is fixedly installed on the top of the support frame, a positioning plate is fixedly installed on the surface of the conveying plate away from the support frame, and swing frames are rotatably installed on both sides of the outer surface of the positioning plate.

The staff places the waste plastic on the inside of the conveying plate, and the tilted conveying plate transports the raw materials through the material guide trough into the separation operation chamber. When the crushing roller rolls the waste scraps, the equipment vibrates, causing the swing frame to drive the material-diverting adsorption piece to swing in the separation operation chamber to prevent the scraps from falling and accumulating under the crushing assembly. A magnetic structure is installed on the surface of the material-diverting adsorption piece to adsorb some metal particles while diverting the material, so as to perform a preliminary separation of the plastic scraps and the metal.

[0007] Preferably, the material-dispensing adsorbent includes a mounting block, two of which are provided, and both mounting blocks are fixedly mounted inside the swing frame, a rotating rod is rotatably mounted between the opposite surfaces of the mounting blocks, a collar and a mounting ring are rotatably mounted on the outer surface of the rotating rod, a material-dispensing piece is fixedly mounted on the outer surface of the collar, an anti-stuck frame is fixedly mounted on the outer surface of the mounting ring, and both the material-dispensing piece and the anti-stuck frame are frictionally adapted to the bottom of the separation operation chamber. When the crushing roller rolls the waste scraps, the equipment vibrates so that the swing frame drives the mounting block to swing back and forth in the separation operation chamber to avoid accumulation and blockage of scraps. During the swinging process, the collar and the mounting ring drive the material-dispensing piece and the anti-stuck frame to rotate on the rotating rod to improve the efficiency of plastic scrap dispensing. The surfaces of the material-dispensing piece and the anti-stuck frame are both provided with a magnetic material structure to perform preliminary separation of metal particles in the plastic scraps.

[0008] Preferably, the crushing assembly includes two mounting seats, each of which has a rotating shaft rotatably mounted on its surface. Crushing rollers are rotatably mounted between opposing surfaces of the rotating shafts. Roller pressure blocks and crushing piercing elements are fixedly mounted on the surfaces of the crushing rollers, respectively. The roller pressure blocks and crushing piercing elements are evenly distributed circumferentially on the surfaces of the crushing rollers. A worker places waste plastic inside a conveyor plate, which is tilted and conveys the material to the top of the crushing rollers. The motor output rotates through a pulley to drive the rotating shaft and crushing rollers. Since the two crushing rollers are respectively connected to the rotating shaft and positioning plate, the material is rolled between the two crushing rollers as the crushing rollers mounted on the rotating shaft rotate. The crushing piercing elements come into contact with the waste plastic as the crushing rollers rotate, crushing it. Since the crushing piercing elements on the two crushing rollers are staggered, the rotation of one crushing roller drives the rotation of the other crushing roller. The two crushing rollers rotate in opposite directions to press the waste plastic, thereby increasing the crushing speed and facilitating the separation of plastic from metal.

[0009] Preferably, the rotating shaft is rotatably connected to the output end of the motor via a pulley, two crushing rollers are provided, and the two crushing rollers are rotatably connected to the rotating shaft and the positioning plate respectively, and the crushing puncture members installed on the surface of the crushing roller are staggered.

A staff member connects the fan to the air supply pipe so that the air flow is transported into the air collecting chamber along the air supply pipe, and blows the plastic scraps that are moved by the material adsorption member to the inclined slope at the bottom of the separation operation chamber along the exhaust port. At this time, the lighter plastic particles are carried by the air flow and slide on the inclined slope. The air flow accelerates the sliding speed of the plastic scraps so that the plastic particles flow toward the side of the discharge port with the air flow; while the heavier metal particles are not easily blown and settle. The magnetic strips mounted on the inclined slope come into contact with the metal particles in the plastic scraps when the plastic scraps slide, so that the metal particles are adsorbed on the magnetic strips and separated from the plastic scraps.

[0012] Preferably, the air supply pipe passes through the separation operation chamber and extends to the interior of the chamber, and the air exhaust port is arranged at an angle, and the air exhaust port is mounted above the magnetic strip through the air collecting chamber.

[0013] Preferably, a waste plastic recycling method with metal separation function consists of the following steps: S1. Raw material conveying: The staff places the waste plastics inside the conveying plate. The inclined conveying plate conveys the raw materials through the guide trough into the separation operation chamber, so that the waste plastics are crushed by the crushing assembly installed in the separation operation chamber; S2, roller crushing: the motor output end rotates to drive the shaft and crushing rollers to rotate. Since there are two crushing rollers, the raw materials rotate between the two crushing rollers along with the crushing rollers installed on the surface of the shaft. The two crushing rollers work together to crush the waste plastics, so as to facilitate the subsequent separation of plastics and metals, realize resource recycling, and reduce pollution to the environment; S3, shaking separation: When the crushing roller rolls the waste plastic, the equipment vibrates, causing the swing frame to drive the material-diverting adsorbent to swing in the separation operation chamber. The crushed waste plastic scraps fall to the bottom of the separation operation chamber. The swinging material-diverting adsorbent diverts the scraps, and the magnetic structure installed on the surface of the material-diverting adsorbent adsorbs some metal particles while diverting the scraps, so as to achieve preliminary separation of the plastic scraps and metals. S4, air flow separation, the swinging material-pickup adsorption piece pushes the plastic scraps toward the side of the discharge port, so that the plastic scraps slide down along the inclined slope set at the bottom of the separation operation chamber. When sliding down, the air flow separation component installed in the separation operation chamber blows the plastic scraps, so that the lighter plastic particles are carried by the air flow and flow toward the side of the discharge port with the air flow, while the heavier metal particles settle down and are adsorbed on the magnetic strip, thereby completing the separation of plastic and metal in the waste plastic.

[0014] The present invention provides a waste plastic recycling device with metal separation function. It has the following beneficial effects: 1. The waste plastic recycling equipment with metal separation function is connected by the staff to the fan and the air supply pipe, so that the air flow is transported into the air collecting chamber along the air supply pipe, and the plastic crumbs moved by the material adsorption component to the inclined slope at the bottom of the separation operation chamber are blown along the exhaust port installed at the bottom of the air collecting chamber. At this time, the lighter plastic particles are carried by the air flow and slide on the inclined slope. The air flow accelerates the sliding speed of the plastic crumbs so that the plastic particles flow to the side of the discharge port with the air flow; while the heavier metal particles are not easily blown and settle down. The magnetic strips installed on the inclined slope plate come into contact with the metal particles in the plastic crumbs when the plastic crumbs slide, so that the metal particles are adsorbed on the magnetic strips and separated from the plastic crumbs.

[0015] 2. This waste plastic recycling equipment with metal separation function has workers place the waste plastics on the inside of the conveyor plate. The inclined conveyor plate transports the raw materials through the material guide trough to the separation operation chamber. When the crushing roller rolls the waste scraps, the equipment vibrates, causing the swing frame to drive the material-pickup adsorption part to swing in the separation operation chamber to prevent the scraps from falling and accumulating under the crushing component.

[0016] 3. This waste plastic recycling equipment with metal separation function, when rolling the waste scraps through the crushing roller, the equipment generates vibration so that the swing frame drives the mounting block to swing back and forth in the separation operation chamber to avoid the accumulation and blockage of scraps. During the swinging process, the ring and the mounting ring drive the material shifting piece and the anti-jamming frame to rotate on the rotating rod to improve the efficiency of plastic scrap shifting. The surfaces of the material shifting piece and the anti-jamming frame are both provided with a magnetic material structure to perform preliminary separation of the metal particles in the plastic scraps.

[0017] 4. The waste plastic recycling equipment with metal separation function has the following steps: the staff places the waste plastic inside the conveying plate, and the inclined conveying plate conveys the raw materials to the top of the crushing roller. The output end of the motor rotates through the pulley to drive the rotating shaft and the crushing roller to rotate. Since the two crushing rollers are respectively connected to the rotating shaft and the positioning plate, the raw materials are rolled between the two crushing rollers as the crushing rollers installed on the rotating shaft rotate. The crushing puncture parts come into contact with the waste plastic as the crushing rollers rotate and crush the waste plastic. Since the crushing puncture parts on the two crushing rollers are staggered, when one crushing roller rotates, it will drive the other crushing roller to rotate. The waste plastic is rolled by the two crushing rollers rotating in opposite directions, thereby increasing the crushing speed to facilitate the separation of plastic and metal.

[0018] 5. This waste plastic recycling equipment with metal separation function, when the two crushing rollers rotate, the staggered crushing and piercing parts can penetrate into waste plastics of different shapes through the piercing knife, inner blade and side blade, crushing the waste plastics to improve the crushing efficiency.

The material guide assembly 6 is fixedly mounted on the side of the top of the frame 1 and extends to the interior of the separation operation chamber 3 through the material guide trough 8; A crushing assembly 4, the crushing assembly 4 being rotatably mounted inside the separation operation chamber 3, and the crushing assembly 4 being rotatably adapted to the material guide assembly 6; The air flow separation component 7 is fixedly mounted on the surface of the separation operation chamber 3 away from the material guide component 6, and the air flow separation component 7 is mounted above the magnetic strip 9. When the staff separates the metal from the waste plastic, they first place the waste plastic inside the material guide component 6. The inclined material guide component 6 transports the raw materials into the separation operation chamber 3 through the material guide trough 8, so that the waste plastic is crushed by the crushing component 4 installed in the separation operation chamber 3. At this time, the crushing component 4 rotated by the motor 5 rolls and crushes the waste plastic. The crushed plastic fragments fall to the bottom of the separation operation chamber 3. The air flow separation component 7 installed in the separation operation chamber 3 blows the plastic fragments, so that the lighter plastic particles are carried by the air flow and flow to the side of the discharge port 2 with the air flow, while the heavier metal particles settle down and adsorb on the magnetic strip 9, thereby completing the separation of plastic and metal in the waste plastic.

[0023] Preferably, the air flow separation assembly 7 includes an air supply pipe 73, a cover plate 72 being rotatably mounted on the outer surface of the air supply pipe 73, an air collecting chamber 71 being fixedly mounted on the outer surface of the air supply pipe 73, and an exhaust port 74 being fixedly mounted on the bottom of the air collecting chamber 71. A worker connects the fan to the air supply pipe 73 so that air is transported along the air supply pipe 73 into the air collecting chamber 71, and blows the plastic scraps that have been moved by the material-pickup adsorption member 64 onto the inclined slope at the bottom of the separation operation chamber 3 along the exhaust port 74 mounted at the bottom of the air collecting chamber 71. At this time, the lighter plastic particles are lifted by the air flow and slide on the inclined slope. The air flow accelerates the sliding speed of the plastic scraps so that the plastic particles flow toward the discharge port 2 with the air flow. The heavier metal particles are not easily blown and settle. The magnetic strips 9 mounted on the inclined slope come into contact with the metal particles in the plastic scraps as they slide, causing the metal particles to be adsorbed by the magnetic strips 9 and separated from the plastic scraps.

[0024] Preferably, the air supply pipe 73 passes through the separation operation chamber 3 and extends to the interior of the chamber. The air exhaust port 74 is tilted and is mounted above the magnetic strip 9 through the air collecting chamber 71 .

[0025] Preferably, a waste plastic recycling method with metal separation function consists of the following steps: S1. Raw material transportation: The staff places the waste plastics inside the conveying plate 61. The inclined conveying plate 61 conveys the raw materials through the guide trough 8 into the separation operation chamber 3, so that the waste plastics are crushed by the crushing assembly 4 installed in the separation operation chamber 3; S2, roller crushing: the output end of the motor 5 rotates to drive the rotating shaft 45 and the crushing roller 41 to rotate. Since there are two crushing rollers 41, the raw material rotates between the two crushing rollers 41 along with the crushing rollers 41 installed on the surface of the rotating shaft 45. The two crushing rollers 41 cooperate to crush the waste plastic, so as to facilitate the subsequent separation of plastic and metal, realize resource recycling, and reduce pollution to the environment; S3, separation by shaking: When the crushing roller 41 rolls the waste plastic, the equipment vibrates, causing the swing frame 62 to drive the material-diverting adsorbent 64 to swing in the separation operation chamber 3. The crushed waste plastic scraps fall to the bottom of the separation operation chamber 3. The swinging material-diverting adsorbent 64 digs the scraps, and the magnetic structure installed on the surface of the material-diverting adsorbent 64 adsorbs some metal particles while diverting the scraps, thereby preliminarily separating the plastic scraps from the metal. S4, air flow separation, the swinging material-moving adsorption member 64 moves the plastic scraps toward the side of the discharge port 2, so that the plastic scraps slide downward along the inclined slope set at the bottom of the separation operation chamber 3. When sliding down, the air flow separation component 7 installed in the separation operation chamber 3 blows the plastic scraps, so that the lighter plastic particles are carried by the air flow and flow toward the side of the discharge port 2 with the air flow, while the heavier metal particles settle down and are adsorbed on the magnetic attraction strip 9, thereby completing the separation of plastic and metal in the waste plastic.

[0026] The second embodiment, based on the first embodiment, see Figures 6 to 8 As shown, preferably, the crushing assembly 4 includes a mounting seat 42, two of which are provided, and a rotating shaft 45 is rotatably mounted on the surface of the two mounting seats 42, and a crushing roller 41 is rotatably mounted between opposite surfaces of the rotating shaft 45, and a roller pressure block 44 and a crushing puncture member 43 are fixedly mounted on the surface of the crushing roller 41, respectively, and the roller pressure block 44 and the crushing puncture member 43 are evenly distributed in a circular shape on the surface of the crushing roller 41. The staff places the waste plastic inside the conveying plate 61, and the inclined conveying plate 61 conveys the raw materials to the top of the crushing roller 41. The output end of the motor 5 rotates through the pulley to drive the rotating shaft 45 and the crushing roller 41 to rotate. Since the two crushing rollers 41 are respectively connected to the rotating shaft 45 and the positioning plate 63, the raw materials are rolled between the two crushing rollers 41 as the crushing roller 41 installed on the rotating shaft 45 rotates. The crushing puncture parts 43 contact the waste plastics and crush the waste plastics as the crushing rollers 41 rotate. Since the crushing puncture parts 43 on the two crushing rollers 41 are staggered, when one crushing roller 41 rotates, it will drive the other crushing roller 41 to rotate. The waste plastics are rolled by the two crushing rollers 41 rotating in opposite directions, thereby increasing the crushing speed to facilitate the separation of plastic and metal.

[0027] Preferably, the rotating shaft 45 is rotatably connected to the output end of the motor 5 through a pulley, and two crushing rollers 41 are provided. The two crushing rollers 41 are rotatably connected to the rotating shaft 45 and the positioning plate 63 respectively, and the crushing puncture members 43 installed on the surface of the crushing roller 41 are staggered.

[0028] Preferably, the crushing and piercing members 43 include connecting blocks 433, which are circumferentially distributed on the surface of the crushing rollers 41. A piercing blade 434 is fixedly mounted in the middle of the outer surface of the connecting blocks 433. An inner blade 431 and a side blade 432 are fixedly mounted on either side of the outer surface of the piercing blade 434. When the two crushing rollers 41 rotate, the staggered crushing and piercing members 43, through the piercing blade 434, inner blade 431, and side blade 432, can penetrate into waste plastics of various shapes, crushing the waste plastics and improving crushing efficiency.

[0029] The third embodiment, based on the first and second embodiments, see Figure 5 、 Figure 6 、 Figure 9 and Figure 10 As shown, preferably, the material guiding assembly 6 includes a support frame 65, a conveying plate 61 is fixedly installed on the top of the support frame 65, a positioning plate 63 is fixedly installed on the surface of the conveying plate 61 away from the support frame 65, and swing frames 62 are rotatably installed on both sides of the outer surface of the positioning plate 63. There are two swing frames 62, and a material-discharging adsorption part 64 is fixedly installed between the opposite surfaces of the two swing frames 62.

[0030] Preferably, the support frame 65 is fixedly mounted on the side of the top of the frame 1. The conveyor plate 61 is tilted above the separation operation chamber 3 via the support frame 65. The positioning plate 63 extends through the material guide trough 8 into the separation operation chamber 3 and is rotatably connected to the crushing assembly 4. Workers place waste plastics inside the conveyor plate 61. The tilted conveyor plate 61 conveys the material through the material guide trough 8 into the separation operation chamber 3. When the crushing roller 41 rolls the waste scraps, the equipment vibrates, causing the swing frame 62 to drive the material-dispensing adsorbent 64 to swing within the separation operation chamber 3 to prevent the scraps from falling and accumulating below the crushing assembly 4. A magnetic structure is mounted on the surface of the material-dispensing adsorbent 64 to absorb some metal particles while dispensing the material, thereby preliminarily separating the plastic scraps from the metal.

[0031] Preferably, the material-prying adsorption component 64 includes a mounting block 641, and two mounting blocks 641 are provided. The two mounting blocks 641 are fixedly mounted inside the swing frame 62, and a rotating rod 646 is rotatably mounted between the opposite surfaces of the mounting block 641. The outer surfaces of the rotating rod 646 are respectively rotatably mounted with a ring 645 and a mounting ring 644. The outer surface of the ring 645 is fixedly mounted with a material-prying piece 642, and the outer surface of the mounting ring 644 is fixedly mounted with an anti-stuck frame 643. The material-prying piece 642 and the anti-stuck frame 643 are both frictionally adapted to the bottom of the separation operation chamber 3. When the crushing roller 41 rolls the waste scraps, the equipment vibrates, causing the swing frame 62 to drive the mounting block 641 to swing back and forth in the separation operation chamber 3 to avoid accumulation and blockage of scraps. During the swinging process, the collar 645 and the mounting ring 644 drive the material-prying piece 642 and the anti-jamming frame 643 to rotate on the rotating rod 646 to improve the efficiency of moving the plastic scraps. The surfaces of the material-prying piece 642 and the anti-jamming frame 643 are both provided with a magnetic material structure to perform preliminary separation of the metal particles in the plastic scraps.

[0032] During use, when separating the metal in the waste plastic, the staff first places the waste plastic inside the material guide component 6. The inclined material guide component 6 transports the raw materials through the material guide trough 8 to the separation operation chamber 3, so that the waste plastic is crushed by the crushing component 4 installed in the separation operation chamber 3. At this time, the crushing component 4 rotated by the motor 5 rolls and crushes the waste plastic. The crushed plastic fragments fall to the bottom of the separation operation chamber 3. The airflow separation component 7 installed in the separation operation chamber 3 blows the plastic fragments, so that the lighter plastic particles are carried by the airflow and flow to the side of the discharge port 2 with the airflow, while the heavier metal particles settle down and adsorb on the magnetic strip 9, thereby completing the separation of plastic and metal in the waste plastic.

[0033] Workers place waste plastics inside conveyor plate 61, which is tilted and conveys the material through guide trough 8 into separation chamber 3. As crushing rollers 41 roll the waste, the equipment vibrates, causing swing frame 62 to swing material-dispensing adsorbent 64 within separation chamber 3, preventing the waste from falling and accumulating beneath crushing assembly 4. A magnetic structure mounted on the surface of adsorbent 64 simultaneously absorbs some metal particles, achieving a preliminary separation of plastic waste from metal.

[0034] The staff places the waste plastic inside the conveying plate 61, and the inclined conveying plate 61 conveys the raw materials to the top of the crushing roller 41. The output end of the motor 5 rotates through the pulley to drive the rotating shaft 45 and the crushing roller 41 to rotate. Since the two crushing rollers 41 are respectively connected to the rotating shaft 45 and the positioning plate 63, the raw materials are rolled between the two crushing rollers 41 as the crushing roller 41 installed on the rotating shaft 45 rotates. The crushing puncture parts 43 contact the waste plastics and crush the waste plastics as the crushing rollers 41 rotate. Since the crushing puncture parts 43 on the two crushing rollers 41 are staggered, when one crushing roller 41 rotates, it will drive the other crushing roller 41 to rotate. The waste plastics are rolled by the two crushing rollers 41 rotating in opposite directions, thereby increasing the crushing speed to facilitate the separation of plastic and metal.

[0035] When the two crushing rollers 41 rotate, the staggered crushing puncture members 43 can penetrate into waste plastics of different shapes through the puncture knife 434, the inner blade 431 and the side blade 432, and crush the waste plastics to improve the crushing efficiency.

[0036] When the crushing roller 41 rolls the waste scraps, the equipment vibrates, causing the swing frame 62 to drive the mounting block 641 to swing back and forth in the separation operation chamber 3 to avoid accumulation and blockage of scraps. During the swinging process, the collar 645 and the mounting ring 644 drive the material-prying piece 642 and the anti-jamming frame 643 to rotate on the rotating rod 646 to improve the efficiency of moving the plastic scraps. The surfaces of the material-prying piece 642 and the anti-jamming frame 643 are both provided with a magnetic material structure to perform preliminary separation of the metal particles in the plastic scraps.

[0037] The staff connects the fan to the air supply pipe 73 so that the air flow is transported into the air collecting chamber 71 along the air supply pipe 73, and blows the plastic crumbs that are moved by the material adsorption component 64 to the inclined slope at the bottom of the separation operation chamber 3 along the exhaust port 74 installed at the bottom of the air collecting chamber 71. At this time, the lighter plastic particles are carried by the air flow and slide on the inclined slope. The air flow accelerates the sliding speed of the plastic crumbs so that the plastic particles flow to the side of the discharge port 2 with the air flow; while the heavier metal particles are not easily blown and settle down. The magnetic strips 9 installed on the inclined slope plate come into contact with the metal particles in the plastic crumbs when the plastic crumbs slide, so that the metal particles are adsorbed on the magnetic strips 9 and separated from the plastic crumbs.

10. According to the waste plastic recycling equipment with metal separation function according to any one of claims 1 to 9, a waste plastic recycling method with metal separation function is proposed, characterized in that: It consists of the following steps: S1, raw material transportation, the staff places the waste plastics inside the conveying plate (61), and the inclined conveying plate (61) conveys the raw materials through the guide trough (8) into the separation operation chamber (3), so that the waste plastics are crushed by the crushing assembly (4) installed in the separation operation chamber (3); S2, roller crushing, the output end of the motor (5) rotates to drive the rotating shaft (45) and the crushing roller (41) to rotate. Since two crushing rollers (41) are provided, the raw material rotates between the two crushing rollers (41) along with the crushing rollers (41) installed on the surface of the rotating shaft (45). The two crushing rollers (41) cooperate to crush the waste plastic, so as to facilitate the subsequent separation of plastic and metal, realize resource recycling, and reduce pollution to the environment; S3, separation by shaking. When the crushing roller (41) rolls the waste plastic, the equipment generates vibrations, causing the swing frame (62) to drive the material-splitting adsorption member (64) to swing in the separation operation chamber (3). The crushed waste plastic plastic fragments fall to the bottom of the separation operation chamber (3). The swinging material-splitting adsorption member (64) stirs the plastic fragments. A magnetic structure is installed on the surface of the material-splitting adsorption member (64) to adsorb some metal particles while the plastic fragments are being slid, thereby preliminarily separating the plastic fragments from the metal. S4, air flow separation, the swinging material-dispensing adsorption member (64) pushes the plastic scraps toward the side of the discharge port (2), so that the plastic scraps slide down along the inclined slope set at the bottom of the separation operation chamber (3). When sliding down, the air flow separation component (7) installed in the separation operation chamber (3) blows the plastic scraps, so that the lighter plastic particles are carried by the air flow and flow toward the side of the discharge port (2) with the air flow, while the heavier metal particles settle and are adsorbed on the magnetic strip (9), thereby completing the separation of plastic and metal in the waste plastic.
