Description

Technical Field

[0001] The present invention relates to the technical field of waste plastic treatment, and specifically to a waste plastic fine sorting device, method and detection process with human-computer interaction. Background Art

[0002] With the wide application of plastic products in daily life and industrial production, the generation amount of waste plastics shows an increasing trend. Due to their advantages such as light weight, durability, and low cost, plastic products are widely used in many fields such as packaging, construction, electronics, and automobiles. However, a large number of plastic products are discarded after use, becoming waste in the environment and bringing great pressure to the environment. Traditional waste plastic treatment methods face many challenges in dealing with the increasing amount of waste plastics. The development of human-computer interaction technology provides new ideas and methods for waste plastic treatment. Through human-computer interaction, the sorting efficiency and accuracy can be improved, and the environmental problems brought by waste plastics can be better addressed.

[0003] At present, there are certain deficiencies in traditional waste plastic sorting methods. Most sorting devices can only perform simple rough sorting on waste plastics and cannot accurately distinguish waste plastics of different materials. Waste plastics of different materials have different chemical and physical properties. If they are recycled together, it will seriously affect the quality and performance of recycled plastics and limit the scope and value of their reuse. If the size of the mixed waste plastics of different materials after screening is screened, the screened waste plastics still contain mixed waste plastics of multiple materials, resulting in insufficient fineness in the screening of the size of waste plastics and having certain deficiencies. Therefore, we provide a waste plastic fine sorting device and method with human-computer interaction to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art and provide a waste plastic fine sorting device and method with human-computer interaction.

[0006] Furthermore, the salvage mechanism includes a motor 1 fixedly mounted on the outer surface of a support frame, the output end of the motor 1 is fixedly connected to a screw rod 1, and the screw rod 1 rotates with the support frame, and the end of the screw rod 1 away from the motor 1 is fixedly connected to a driving wheel.

[0007] Furthermore, a belt is sleeved on the outer surface of the screw rod 1, the outer surface of the screw rod 1 is threadedly connected to a mounting bracket, the inner wall of the mounting bracket is threadedly connected to the screw rod 2, the end of the screw rod 2 close to the driving wheel is fixedly connected to a driven wheel, and the driven wheel and the driving wheel are connected by a belt transmission.

[0008] Furthermore, a cylinder 2 is fixedly installed on the bottom of the mounting frame, a mounting plate is fixedly connected to the telescopic end of the cylinder 2, a collecting bag is fixedly connected to the bottom of the mounting plate and a cylinder 3 is fixedly installed on the outer surface of the screening box, a push plate is fixedly connected to the telescopic end of the cylinder 3, and the outer surface of the push plate slides with the inner wall of the screening box, a rubber strip is fixedly connected to the outer surface of the push plate, and the rubber strip is plugged into the sealing slot.

[0009] Furthermore, the shaking mechanism includes a second motor fixedly mounted on the bottom of the supporting plate, the output end of the second motor is fixedly connected to a rotating shaft, and the rotating shaft rotates with the supporting plate, and the end of the rotating shaft away from the second motor is fixedly connected to a turntable.

[0010] Furthermore, the inner wall of the turntable is rotatably connected to a connecting rod, and the outer surface of one end of the connecting rod away from the turntable is rotatably connected to a fan-shaped tooth plate, the inner wall of the fan-shaped tooth plate is rotatably connected to a limiting shaft, and the limiting shaft rotates with the supporting plate, the outer surface of the fan-shaped tooth plate is meshingly connected to a gear rod, and the end of the gear rod away from the fan-shaped tooth plate is fixedly connected to the outer surface of the buffer pad.

[0011] Furthermore, the fine sorting method comprises the following steps: S1: injecting a liquid medium into the screening box. The liquid medium is selected according to the waste plastics of different densities. Brine and alcohol can be selected. First, the approximate material range of the waste plastics to be sorted is determined, and the density difference is estimated. Based on this, a liquid medium of appropriate concentration is prepared to ensure that waste plastics of different materials can show obvious floating and sinking differences in the liquid medium; S2: Use the salvaging mechanism to collect the waste plastics with lower density floating on the liquid. First, start the second cylinder to drive the mounting plate and the collecting bag to move downward, so that the collecting bag moves to the appropriate depth of the liquid in the screening box. Then start the first motor to drive the first screw to rotate. The first screw drives the second screw to rotate through the belt. The second screw drives the mounting frame to move to the right. During the movement of the mounting frame to the right, the collecting bag on it moves with it, and the waste plastics floating on the liquid are picked up and collected in the collecting bag. S3: The collected waste plastics with lower density are placed on the screening bucket. During operation, the waste plastics in the collection bag are transferred to the screening bucket through the corresponding grabbing device or manual operation to ensure that the waste plastics can be evenly placed on the surface of the screening bucket for subsequent screening operations; S4: The waste plastics with high density are screened by the shaking mechanism. The motor 2 is started to drive the rotating shaft to rotate, and the rotating shaft drives the turntable to rotate. The turntable drives the fan-shaped tooth plate to swing through the connecting rod. The fan-shaped tooth plate is engaged with the tooth bar, driving the tooth bar to move left and right, thereby driving the screening bucket, the slider and the buffer pad to follow the left and right movement, thereby causing the screening bucket to vibrate. Under the action of vibration, the waste plastics with high density and small size fall into the collection box through the sieve holes on the screening bucket for centralized collection, while the waste plastics with large size cannot pass through the sieve holes and still remain on the screening bucket; S5: Take out the waste plastics with larger sizes on the screening bucket. You can do it manually or use the corresponding grabbing device to transfer the waste plastics with larger sizes left on the screening bucket to the designated collection area for further processing. At the same time, the waste plastics with larger density settle at the bottom of the screening box. Through the cooperation between the pushing mechanism, the cylinder 1, the blanking plate, and the guide block, the waste plastics with larger density are taken out from the bottom of the screening box and fall into the screening bucket. Specifically, the cylinder 3 pushes the push plate to move rightward, and the push plate pushes the waste plastics settled at the bottom to the left until the rubber strip is inserted into the sealing slot. Then, the cylinder 1 controls the blanking plate to move downward so that it drives the waste plastics to move out of the bottom of the screening box. The waste plastics move from the inclined part of the blanking plate to the guide block, and then the waste plastics fall into the screening bucket through gravity. S6: Repeat steps S4 and S5 to screen the waste plastics made of denser materials again by size, so as to ensure the effective separation of waste plastics of different sizes. When repeating the operation, restart the jitter mechanism for vibrating screening to further separate the waste plastics of different sizes that may remain. At the same time, check again whether there are still waste plastics of larger sizes on the screening hopper that need to be taken out, and whether there are waste plastics made of denser materials that have not been completely transferred from the bottom of the screening box to the screening hopper. If necessary, continue with the corresponding operations until the waste plastics of different sizes are completely separated.

[0012] Compared with the prior art, the waste plastic fine sorting equipment and method with human-computer interaction have the following beneficial effects: In the present invention, by injecting a suitable liquid medium into the screening box and utilizing the density difference of waste plastics made of different materials, it is ensured that waste plastics made of different materials can show obvious floating and sinking differences in this liquid medium. The floating waste plastics with smaller density above the liquid can be fished out by the fishing mechanism, while the waste plastics with larger density sink to the bottom of the screening box and are then taken out through the cooperation of the pushing mechanism, cylinder one and the blanking plate, so as to realize the separation of waste plastics made of different materials. By setting up structures such as the jitter mechanism and the screening hopper, waste plastics of different sizes can be screened, and through the cooperation of each component, a fine screening effect of the size of mixed waste plastics made of different materials is achieved.

[0013] In the present invention, by starting cylinder three to drive the pushing plate to move, at the same time the pushing plate will drive the rubber strip to insert into the sealing slot. This structural design can not only effectively push the waste plastics settled at the bottom of the screening box, but also ensure the sealing of the screening box, prevent a large amount of liquid leakage caused by the discharge of waste plastics with large density, and ensure the normal operation of the equipment.

[0019] In this embodiment, the base 1 is the basic support structure of the entire device, usually made of a strong and corrosion-resistant metal material such as stainless steel, with a flat bottom, which enables the device to be placed stably on the ground or workbench, providing a stable working environment for subsequent sorting operations and avoiding affecting the accuracy of sorting due to device shaking. The screening box 2, as a key component for waste plastic sorting, can be made of high-strength transparent plastic or stainless steel. The advantage of the transparent material is that it is convenient for operators to directly observe the sorting situation inside the box, while the stainless steel material has excellent durability and corrosion resistance. Its shape is a cuboid, and the internal space is reasonably planned to ensure that it can accommodate an appropriate amount of liquid medium and waste plastic to meet the sorting requirements. The support frame 3 is generally made of a metal material such as aluminum alloy, which has the characteristics of light weight and high strength. Its main function is to provide a stable support for the screening box 2, ensuring that the screening box 2 remains stable during operation and will not tilt or shake due to external interference, thus guaranteeing the accuracy and stability of the sorting process. The fishing mechanism 4 is used to fish out the waste plastic floating above the liquid, and its various components cooperate closely to achieve efficient fishing operations. The purpose of the pushing mechanism 5 is to perform specific operations on the waste plastic in the box to assist the sorting process. The sealing slot 6 is provided to cooperate with relevant components to achieve a good sealing effect, prevent liquid leakage, and ensure the stability and reliability of the sorting environment.

The guide rod 10 is usually a slender rod-shaped structure made of a metal material, with a smooth surface. Its main function is to provide accurate guidance for the slider 11, ensuring that the slider 11 can slide smoothly on its surface, thereby ensuring the position accuracy of the screening bucket 12 connected thereto and further affecting the sorting accuracy. The slider 11 is made of wear-resistant metal or plastic material, and its shape matches that of the guide rod 10 and can closely fit and slide on the guide rod 10. The buffer pad 13 is generally made of rubber or other elastic materials, and its function is to buffer and protect when the screening bucket 12 is vibrated or impacted, avoiding excessive impact and damage to the screening bucket 12 and the waste plastic inside it. The bearing plate 14 is usually made of a metal material, and its function is to provide installation support for the shaking mechanism 15, ensuring that the shaking mechanism 15 can operate stably, thereby effectively driving the screening bucket 12 to vibrate and realizing the screening of the size of waste plastic.

[0020] The working steps of this embodiment are as follows: like Figures 1 - 8 As shown, by injecting a suitable liquid medium into the screening box 2, the density difference of waste plastics of different materials is utilized to ensure that waste plastics of different materials can show obvious floating and sinking differences in the liquid medium, and the waste plastics with lower density floating on the liquid can be fished out by the salvaging mechanism 4, and finally the screening bucket 12 is driven by the shaking mechanism 15 to swing back and forth, thereby realizing the separation of waste plastics of different materials, and the waste plastics with higher density settle at the bottom of the screening box 2, and then the waste plastics that have sunk to the bottom are pushed onto the blanking plate 8 by the pushing mechanism 5, and the blanking plate 8 is driven to move downward by starting the cylinder 7 to drive the waste plastics to move out of the screening box 2, and then the waste plastics fall on the guide block 9, and finally fall into the screening bucket 12, and similarly, the screening bucket 12 is driven by the shaking mechanism 15 to swing back and forth, thereby realizing the separation of waste plastics of different materials, so that waste plastics of different sizes can be screened, and through the cooperation between the various components, the fine screening effect of the size of mixed waste plastics of different materials is realized. Example 2

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the salvage mechanism 4 includes a motor 401 fixedly mounted on the outer surface of the support frame 3, the output end of the motor 401 is fixedly connected to a screw rod 402, and the screw rod 402 rotates with the support frame 3, the end of the screw rod 402 away from the motor 401 is fixedly connected to a driving wheel 403, the outer surface of the screw rod 402 is sleeved with a belt 404, the outer surface of the screw rod 402 is threadedly connected to a mounting frame 405, the inner wall of the mounting frame 405 is threadedly connected to a screw rod 2 406, the end of the screw rod 2 406 close to the driving wheel 403 is fixedly connected to a driven wheel 407, and the driven wheel 407 and the driving wheel 403 are connected through the belt 404, the bottom of the mounting frame 405 is fixedly mounted with a cylinder 2 408, the telescopic end of the cylinder 2 408 is fixedly connected to a mounting plate 409, and the bottom of the mounting plate 409 is fixedly connected to a collecting bag 410.

[0022] In this embodiment, the first motor 401 serves as the power source of the entire salvage mechanism 4. Generally, a high-performance DC motor is adopted. Its material shell is usually made of metal, such as aluminum alloy, which has good heat dissipation performance and mechanical strength. Key components such as the motor winding and rotor inside are made of high-quality electromagnetic materials to ensure stable power output. This material and structural design enable the first motor 401 to work continuously and stably for a long time, providing reliable power support for subsequent salvage operations. The first lead screw 402 is usually made of high-strength metal, such as stainless steel. Its shape is a slender cylinder, and its surface is finely processed, with high smoothness and precision. This material and shape design enable the first lead screw 402 to rotate smoothly on the support frame 3 and can withstand large axial forces and torques, ensuring that it will not bend or deform during the transmission process. The driving wheel 403 is tightly connected to the first lead screw 402 and is usually made of metal, such as steel. Its shape is disc-shaped, and its surface has tooth grooves matching the belt 404. This material and shape design of the driving wheel 403 can ensure good friction and transmission efficiency with the belt 404, effectively transmitting the power of the first motor 401 to the belt 404. The belt 404 is made of high-strength rubber material, and it has a multi-layer fiber-reinforced structure inside to increase the strength and wear resistance of the belt 404. The shape of the belt 404 is annular, and its width and thickness are designed according to specific transmission requirements. This material and shape design enable the belt 404 to maintain good elasticity and flexibility under the condition of bearing large tensile forces, effectively transmit power, and can adapt to different working environments, and is not prone to aging, fracture, etc. The mounting bracket 405 is a metal structure and is usually made of aluminum alloy. Its shape is frame-shaped, with multiple mounting holes and connection parts to facilitate the installation of other components. This material and shape design enable the mounting bracket 405 to have sufficient strength to support subsequent components and also have a light weight, facilitating movement on the first lead screw 402. The second lead screw 406 usually adopts the same material and processing technology as the first lead screw 402 to ensure the consistency and stability of the transmission. The material and shape of the driven wheel 407 are similar to those of the driving wheel 403, and it is also made of metal, such as steel, with a disc-shaped shape and tooth grooves matching the belt 404 on its surface. Through the transmission of the belt 404, the driven wheel 407 can rotate with the rotation of the driving wheel 403, thereby driving the second lead screw 406 to rotate. This transmission method can not only achieve power transmission but also adjust the transmission accuracy and efficiency by adjusting the tightness of the belt 404. The second cylinder 408 is made of metal, such as stainless steel. Its internal key components such as pistons and cylinder barrels are manufactured by high-precision processing technology to ensure good sealing performance and telescopic performance. The mounting plate 409 is a metal thin plate structure and is usually made of aluminum alloy. Its shape is rectangular, and its surface is flat and smooth.This material and shape design enable the mounting plate 409 to be stably mounted on the telescopic end of the second cylinder 408 and to be tightly connected to the collection hopper 410. The collection hopper 410 is usually made of metal mesh or high-strength plastic, such as stainless steel mesh or polycarbonate plastic. When using metal mesh, its material has good strength and air permeability, can bear a certain weight of waste plastic, and is convenient for the liquid in the waste plastic to flow out; when using high-strength plastic, it has a lighter weight and good flexibility, which is convenient for operation and cleaning. The shape of the collection hopper 410 is funnel-shaped with a large opening, which is convenient for collecting waste plastic floating on the liquid surface, and has a certain constriction at the bottom, which is convenient for concentrating the collected waste plastic together.

[0023] The working steps of this embodiment are as follows: As Figure 1 、 Figure 2 、 Figure 3 and Figure 7 shown, when it is necessary to centrally collect waste plastic with a smaller density floating above the liquid, the second cylinder 408 is started to drive the mounting plate 409 and the collection hopper 410 to move downward, so that the collection hopper 410 moves to an appropriate depth in the liquid in the screening box 2. Then, the first motor 401 is started to drive the first lead screw 402 to rotate. The first lead screw 402 drives the second lead screw 406 to rotate through the belt 404. The second lead screw 406 drives the mounting frame 405 to move to the right. During the movement of the mounting frame 405 to the right, the collection hopper 410 thereon moves along with it, scooping up the waste plastic floating above the liquid, so that it can be collected in the collection hopper 410. Embodiment 3

[0024] As Figure 1 、 Figure 4 and Figure 6 shown, the pushing mechanism 5 includes a third cylinder 501 fixedly installed on the outer surface of the screening box 2. The telescopic end of the third cylinder 501 is fixedly connected with a pushing plate 502, and the outer surface of the pushing plate 502 slides on the inner wall of the screening box 2. The outer surface of the pushing plate 502 is fixedly connected with a rubber strip 503, and the rubber strip 503 is inserted into the sealing slot 6.

[0025] In this embodiment, the cylinder three 501 serves as the power source for pushing the waste plastics settled at the bottom of the screening box 2. It is usually made of metal, such as stainless steel. Its internal structure includes key components such as a piston and a cylinder barrel. These components are manufactured using high-precision processing techniques to ensure good sealing performance and telescopic performance. This material and structure design enable the cylinder three 501 to stably output power and effectively push the pushing plate 502 to move. The material of the pushing plate 502 is generally metal, such as aluminum alloy. Its shape is a rectangular plate with a smooth surface. This material and shape design enable the pushing plate 502 to smoothly slide on the inner wall of the screening box 2 and effectively transfer the force to the waste plastics. The rubber strip 503 is usually made of wear-resistant and corrosion-resistant rubber material. Its shape is a long strip and is parallel to the long side of the pushing plate 502. This material and shape design of the rubber strip 503 enable it to play a good sealing role when contacting the sealing slot 6, preventing liquid from leaking from the gap between the pushing plate 502 and the inner wall of the screening box 2.

[0026] The working steps of this embodiment are as follows: As Figure 1 、 Figure 4 and Figure 6 shown, by starting the cylinder three 501 to drive the pushing plate 502 to move, at the same time the pushing plate 502 will drive the rubber strip 503 to insert into the sealing slot 6. This structural design can not only effectively push the waste plastics settled at the bottom of the screening box 2, but also ensure the sealing performance of the screening box 2, preventing a large amount of liquid leakage caused by the discharge of high-density waste plastics, and ensuring the normal operation of the equipment.

[0028] In this embodiment, the second motor 1501 serves as the power source of the jitter mechanism 15. Generally, a high-performance AC motor is adopted. Its material shell is usually made of metal, such as aluminum alloy, which has good heat dissipation performance and mechanical strength. Key components such as the motor winding and rotor inside are made of high-quality electromagnetic materials to ensure stable power output. This material and structural design enable the second motor 1501 to work continuously and stably for a long time, providing reliable power support for subsequent jitter operations. The rotating shaft 1502 is usually made of high-strength metal, such as stainless steel. Its shape is a slender cylinder, and its surface has been finely processed, with high smoothness and precision. This material and shape design enable the rotating shaft 1502 to rotate smoothly on the bearing plate 14 and can withstand large axial forces and torques, ensuring that it will not bend or deform during the transmission process. The turntable 1503 is tightly connected to the rotating shaft 1502 and is usually made of metal, such as steel. Its shape is disc-shaped, and its surface is smooth to facilitate the connection and rotation of the connecting rod 1504. The material of the connecting rod 1504 is generally metal, such as aluminum alloy. Its shape is a slender rod, and its surface is smooth. This material and shape design enable the connecting rod 1504 to rotate smoothly on the inner wall of the turntable 1503 and can effectively transmit power. The material of the sector gear plate 1505 is generally metal, such as aluminum alloy. Its shape is sector-shaped, and its surface has tooth grooves matching the toothed rod 1507. This material and shape design enable the sector gear plate 1505 to effectively mesh with the toothed rod 1507 and can transmit power during rotation. The inner wall of the sector gear plate 1505 is rotatably connected to the limiting shaft 1506. The limiting shaft 1506 rotates with the bearing plate 14. The material of the limiting shaft 1506 is usually metal, such as steel. Its shape is a cylinder, and its surface is smooth to facilitate the rotation and positioning of the sector gear plate 1505. The material of the toothed rod 1507 is generally metal, such as aluminum alloy. Its shape is a slender rod, and its surface has tooth grooves matching the sector gear plate 1505. This material and shape design enable the toothed rod 1507 to effectively mesh with the sector gear plate 1505 and can transmit power during rotation. And one end of the toothed rod 1507 away from the sector gear plate 1505 is fixedly connected to the outer surface of the buffer pad 13. The buffer pad 13 is usually made of rubber or other elastic materials. Its function is to buffer and protect when the screening hopper 12 is vibrated or impacted, avoiding excessive impact and damage to the screening hopper 12 and the waste plastics inside it.

[0029] The working steps of this embodiment are as follows: Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 8As shown, starting the second motor 1501 can drive the rotation of the rotating shaft 1502. The rotating shaft 1502 drives the rotation of the turntable 1503. The turntable 1503 drives the swinging of the sector gear plate 1505 through the connecting rod 1504. The sector gear plate 1505 meshes with the toothed rod 1507, driving the toothed rod 1507 to move left and right, thereby driving the screening hopper 12, the slider 11, and the buffer pad 13 to move left and right accordingly, and further causing the screening hopper 12 to vibrate, so that the size of the waste plastic can be screened smoothly.

8. A fine sorting device for waste plastics for human-computer interaction according to any one of claims 1-7, characterized in that: The fine sorting method comprises the following steps: S1: injecting a liquid medium into the screening box (2). The liquid medium is selected according to the waste plastics of different densities. Salt water or alcohol can be selected. First, the approximate material range of the waste plastics to be sorted is determined, and the density difference is estimated. Based on this, a liquid medium of appropriate concentration is prepared to ensure that waste plastics of different materials can show obvious floating and sinking differences in the liquid medium. S2: Using the salvaging mechanism (4), the waste plastics with a lower density floating on the liquid are collected and collected. First, the second cylinder (408) is started to drive the mounting plate (409) and the collecting bag (410) to move downward, so that the collecting bag (410) moves to a suitable depth of the liquid in the screening box (2). Then, the motor (401) is started to drive the screw rod (402) to rotate. The screw rod (402) drives the screw rod (406) to rotate through the belt (404). The screw rod (406) drives the mounting frame (405) to move rightward. When the mounting frame (405) moves rightward, the collecting bag (410) thereon moves along with it, and the waste plastics floating on the liquid are scooped up and collected in the collecting bag (410); S3: placing the collected waste plastics with a lower density on the screening bucket (12); during operation, the waste plastics in the collection bag (410) are transferred to the screening bucket (12) through a corresponding grabbing device or manual operation, ensuring that the waste plastics can be evenly placed on the surface of the screening bucket (12) for subsequent screening operations; S4: The waste plastics with a relatively high density are screened by size through the shaking mechanism (15), and the motor 2 (1501) is started to drive the rotating shaft (1502) to rotate. The rotating shaft (1502) drives the rotating disk (1503) to rotate. The rotating disk (1503) drives the fan-shaped tooth plate (1505) to swing through the connecting rod (1504). The fan-shaped tooth plate (1505) meshes with the tooth bar (1507), driving the tooth bar (1507) to move left and right, thereby driving the screening bucket (12), the slider (11) and the buffer pad (13) to follow the left and right movement, thereby causing the screening bucket (12) to vibrate. Under the action of vibration, the waste plastics with a relatively high density and a relatively small size fall into the collection box (16) through the sieve holes on the screening bucket (12) and are collected in a centralized manner, while the waste plastics with a relatively large size cannot pass through the sieve holes and remain on the screening bucket (12); S5: Remove the larger-sized waste plastics on the screening hopper (12), which can be manually removed or using a corresponding grasping device to transfer the larger-sized waste plastics remaining on the screening hopper (12) to a designated collection area for subsequent further processing. At the same time, the waste plastics made of denser materials settle at the bottom of the screening box (2). Through the mutual cooperation among the pushing mechanism (5), the first cylinder (7), the blanking plate (8), and the guiding block (9), the waste plastics with a large density are taken out from the bottom of the screening box (2) and made to fall into the screening hopper (12). Specifically: The third cylinder (501) pushes the pushing plate (502) to move to the right. The pushing plate (502) pushes the waste plastics settled at the bottom to the left until the rubber strip (503) is inserted into the sealing slot (6). Then, the first cylinder (7) controls the blanking plate (8) to move downward, driving the waste plastics to move out from below the screening box (2). The waste plastics move from the inclined part of the blanking plate (8) to the guiding block (9), and then the waste plastics fall into the screening hopper (12) under the action of gravity. S6: Repeat steps S4 and S5 to screen the waste plastics made of denser materials again for their size to ensure the effective separation of waste plastics of different sizes. When repeating the operation, restart the jitter mechanism (15) for vibrating screening to further separate the waste plastics of different sizes that may remain. At the same time, check again whether there are still larger-sized waste plastics on the screening hopper (12) that need to be removed, and whether there are waste plastics with a large density that have not been completely transferred from the bottom of the screening box (2) to the screening hopper (12).
