Description

Technical Field

[0001] This utility model belongs to the field of waste plastic recycling technology, and specifically relates to a sorting device for waste plastic recycling. Background Technology

[0002] Waste plastics refer to discarded plastic products after consumption or use, formally known as post-consumer plastic waste. These plastic products are widely used in daily life, such as plastic bags and plastic bottles. When they reach the end of their service life or have completed their purpose, they are discarded and become waste plastics. The vast majority of plastic products, especially a large number of single-use products, do not undergo significant changes in the properties of the plastic material itself after use. Therefore, they can be completely recycled and reprocessed into plastic products for reuse using appropriate methods.

[0003] With the widespread use of plastic products, the number of waste plastic bottles is also increasing. Recycling waste plastic bottles can not only reduce resource waste but also reduce environmental pollution. However, due to the wide variety of waste plastic bottles, with different shapes, sizes, and colors, the traditional sorting method mainly involves placing the plastic bottles on a conveyor platform for manual sorting. This causes the plastic bottles to accumulate on the conveyor platform, requiring operators to manually separate the accumulated waste plastic bottles, which consumes more manpower and time and affects the sorting efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a sorting device for recycling waste plastics to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a sorting device for recycling waste plastics, including a base, a conveying component installed on the base, a discharge pipe installed at one end of the base, a feeding hopper installed at the upper end of the discharge pipe, a discharge component installed inside the feeding hopper, a driving component installed on one side of the discharge component, a control component installed inside the discharge component, and a blocking component installed on one side of the discharge bin.

[0008] The feeding hopper is used to pour in waste plastic bottles, the driving component is used to drive the discharging component to rotate, so as to transport the waste plastic bottles in the feeding hopper to the discharging pipe. The waste plastic bottles in the discharging pipe can fall onto the conveying component for conveying. The control component can adjust the amount conveyed by the discharging component. The blocking component is used to spread out the accumulated waste plastic bottles.

[0009] Furthermore, the discharge assembly includes a discharge roller, which is rotatably installed inside the feed hopper. The discharge roller has a symmetrically designed discharge chamber inside its cavity, and the discharge chamber has an opening on its surface.

[0010] Furthermore, the control component includes a rotating shaft, which is rotatably mounted inside the discharge drum. Arc-shaped rotating blocks are symmetrically mounted on the rotating shaft. The outer surfaces of the arc-shaped rotating blocks are all in contact with the inner wall of the discharge bin. The arc-shaped rotating blocks can all rotate inside the discharge bin to change the storage capacity of the discharge bin.

[0011] Furthermore, an adjusting disc is coaxially mounted on the rotating shaft, the adjusting disc being able to slide with the slot, a spring is mounted around the outside of the adjusting disc around the rotating shaft, a spring fixing plate is mounted on the center of one end of the outer side of the rotating shaft, a plurality of fixing holes are evenly opened on the adjusting disc, and fixing rods are symmetrically mounted on one side of the discharge roller, the fixing rods fitting into the fixing holes.

[0012] Furthermore, the drive assembly includes a motor, an mounting plate is installed on one side of the feed hopper, the motor is mounted on the mounting plate, a drive shaft is mounted on the motor shaft, and one end of the discharge roller is mounted on one end of the drive shaft.

[0013] Furthermore, a positioning groove is provided through one end of the discharge pipe, and the blocking assembly includes a blocking plate. Both ends of the blocking plate are slidably installed in the positioning groove, and the lower end of the blocking plate is provided with a certain tilt angle.

[0014] Furthermore, two fixing grooves are formed through the surface of the baffle plate, and two fixing seats are installed at one end of the discharge pipe. Each fixing seat is equipped with a screw, which can slide with the fixing groove. Each screw is threaded with a nut.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model enables intermittent conveying of waste plastic bottles through the discharge component, preventing excessive accumulation on the conveying component. Furthermore, the control component allows for adjustment of the discharge volume per cycle, accommodating a wider range of conveying scenarios and enhancing practicality. The blocking component spreads the waste plastic bottles on the conveying component, further preventing accumulation and facilitating sorting by workers. Ultimately, this device prevents waste plastic bottles from accumulating on the conveying component, eliminating the need for manual separation, saving time and effort, and improving sorting efficiency.

[0017] 2. This utility model uses a screw and nut to fix the position of the baffle plate, allowing it to stably spread out the accumulated waste plastic bottles. When the size of the waste plastic bottles changes, the position of the baffle plate can be loosened by rotating the nut, allowing the baffle plate to slide manually in its positioning groove. This causes the screw to slide in its fixing groove. When the reserved height below the baffle plate matches the size of the waste plastic bottles, the position of the baffle plate can be fixed again by the nut. This avoids the problem of the waste plastic bottles being blocked by the baffle plate due to changes in size and no longer being transported normally on the conveying component. This device can adapt to waste plastic bottles of different sizes for sorting operations, spreading them out on the conveying component for easy sorting by workers.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is a sorting device for recycling waste plastics, including a base 1, a conveying component 2 installed on the base 1, a discharge pipe 3 installed at one end of the base 1, a feeding hopper 4 installed at the upper end of the discharge pipe 3, a discharge component 5 installed inside the feeding hopper 4, a driving component 6 installed on one side of the discharge component 5, a control component 7 installed inside the discharge component 5, and a blocking component 8 installed on one side of the discharge bin 10.

[0032] The feeding hopper 4 is used to pour in waste plastic bottles. The driving component 6 is used to drive the discharging component 5 to rotate, so as to transport the waste plastic bottles in the feeding hopper 4 to the discharging pipe 3. The waste plastic bottles in the discharging pipe 3 can fall onto the conveying component 2 for conveying. The control component 7 can adjust the amount conveyed by the discharging component 5. The blocking component 8 is used to spread out the accumulated waste plastic bottles.

[0033] In practical use, waste plastic bottles are poured into the feed hopper 4, and the drive component 6 drives the discharge component 5 to rotate. The discharge component 5 then transports the waste plastic bottles in the feed hopper 4 to the discharge pipe 3, allowing for intermittent transport of waste plastic bottles. The conveying capacity of the discharge component 5 can be changed by adjusting the control component 7, enabling applications in more conveying scenarios. When the waste plastic bottles enter the discharge pipe 3, they fall onto the conveying component 2, which facilitates the sorting of different types of waste plastic bottles by personnel. The blocking component 8 can spread out the waste plastic bottles piled up on the conveying component 2, preventing them from accumulating and facilitating manual sorting.

[0034] This invention enables intermittent conveying of waste plastic bottles via the discharge component 5, preventing excessive accumulation on the conveying component 2. The control component 7 allows for adjustments to the conveying volume of the discharge component 5 each time, facilitating application in various conveying scenarios and enhancing practicality. Furthermore, the blocking component 8 spreads the waste plastic bottles on the conveying component 2, further preventing accumulation and facilitating sorting by workers. Ultimately, this device prevents waste plastic bottles from accumulating on the conveying component 2, eliminating the need for manual separation, saving time and effort, and improving sorting efficiency.

[0035] In one embodiment, the discharge assembly 5 includes a discharge roller 9, which is rotatably installed in the feed hopper 4. The discharge roller 9 has a symmetrically designed discharge chamber 10 inside its cavity, and the discharge chamber 10 has an opening on its surface.

[0036] By installing the discharge roller 9, the feed hopper 4 and the discharge pipe 3 can be blocked and separated, so that a certain amount of waste plastic bottles are first stored in the discharge bin 10. Then, the discharge roller 9 is driven by the drive component 6 to rotate, which causes the discharge bin 10 to rotate, thereby conveying the waste plastic bottles into the feed hopper 4, and then to the conveying component 2 for sorting. This solves the problem of excessive waste plastic bottles accumulating on the conveying component 2, making it inconvenient for manual sorting.

[0037] In one embodiment, the control component 7 includes a rotating shaft 11, which is rotatably mounted inside the discharge roller 9. Arc-shaped rotating blocks 12 are symmetrically mounted on the rotating shaft 11. The outer surfaces of the arc-shaped rotating blocks 12 are all in contact with the inner wall of the discharge bin 10. The arc-shaped rotating blocks 12 can all rotate inside the discharge bin 10 to change the storage capacity of the discharge bin 10.

[0038] The rotating shaft 11 can drive the arc-shaped rotating block 12 to rotate within its discharge bin 10, thereby changing the volume of the discharge bin 10 and thus flexibly adjusting the amount of waste plastic bottles it conveys, enabling it to be applied to more demanding conveying scenarios and improving its practicality.

[0039] In one embodiment, for the aforementioned rotating shaft 11, an adjusting disc 14 is coaxially mounted on the rotating shaft 11. The adjusting disc 14 can slide with the slot 13. A spring 15 is mounted around the outside of the adjusting disc 14 around the rotating shaft 11. A spring 15 fixing plate is mounted on the center of one end of the outer side of the rotating shaft 11. A plurality of fixing holes 17 are evenly opened on the adjusting disc 14. A fixing rod 18 is symmetrically mounted on one side of the discharge roller 9. The fixing rod 18 fits into the fixing holes 17.

[0040] When the conveying volume needs to be adjusted, the adjusting plate 14 can be moved within the slot 13 by pulling it, so that the fixing rod 18 no longer fixes the adjusting plate 14. This allows the adjusting plate 14 to rotate, causing the rotating shaft 11 to rotate. The rotating shaft 11 then drives the arc-shaped rotating block 12 to rotate within its discharge bin 10, thus changing the volume of the discharge bin 10. Once the desired volume is reached, the adjusting plate 14 is no longer in contact with the adjusting plate. Under the compression force of the spring 15, the fixing hole 17 re-enters the fixing rod 18, thus fixing it in place. This ensures that the arc-shaped rotating block 12 will not move when the discharge roller 9 rotates, allowing the conveying to continue according to the adjusted volume. This enables flexible adjustment of the conveying volume of waste plastic bottles as needed.

[0041] In one embodiment, the drive assembly 6 includes a motor 19, an mounting plate 20 is installed on one side of the feed hopper 4, the motor 19 is mounted on the mounting plate 20, a drive shaft 21 is mounted on the axis of the motor 19, and one end of the discharge roller 9 is mounted on one end of the drive shaft 21.

[0042] By driving the motor 19 mounted on the mounting plate 20, the discharge roller 9 can be rotated via the drive shaft 21. This allows the waste plastic bottles in the feed hopper 4 to be intermittently transported to the conveying assembly 2 by the rotation of the discharge roller 9. This avoids the problem of excessive waste plastic bottles accumulating on the conveying assembly 2, which would make manual sorting inconvenient.

[0043] In one embodiment, for the above-mentioned discharge pipe 3, a positioning groove 22 is provided through one end of the discharge pipe 3, and the blocking component 8 includes a blocking plate 23. Both ends of the blocking plate 23 are slidably installed in the positioning groove 22, and the lower end of the blocking plate 23 is provided with a certain tilt angle.

[0044] By sliding the baffle plate 23 in the positioning groove 22, the baffle plate 23 can block the waste plastic bottles conveyed on the conveying component 2. Thus, the baffle plate 23 can spread out the waste plastic bottles accumulated on the conveying component 2, thereby further preventing the waste plastic bottles from accumulating on the conveying component 2. This device can solve the problem of waste plastic bottles accumulating on the conveying component 2, making it easier for manual sorting operations.

[0045] In one embodiment, for the aforementioned baffle plate 23, two fixing grooves 24 are formed through the surface of the baffle plate 23, and two fixing seats 25 are installed at one end of the discharge pipe 3. Each fixing seat 25 is equipped with a screw 26, and each screw 26 can slide with the fixing groove 24. Each screw 26 is threaded with a nut 27.

[0046] The position of the baffle plate 23 can be fixed by the screw 26 and the nut 27, so that the accumulated waste plastic bottles can be stably spread out. When the size of the waste plastic bottles changes, the position of the baffle plate 23 can be unfixed by rotating the nut 27, so that the baffle plate 23 can be manually moved to slide in its positioning groove 22, and the screw 26 will slide in its fixing groove 24. When the reserved height below the baffle plate 23 is consistent with the size of the waste plastic bottles, the position of the baffle plate 23 can be fixed again by the nut 27, so as to avoid the problem that the waste plastic bottles will be blocked by the baffle plate 23 due to changes in the size of the waste plastic bottles and will no longer be conveyed normally on the conveying assembly 2. This device can adapt to waste plastic bottles of different sizes for sorting operations, spread them out on the conveying assembly 2, and facilitate workers to sort them.

[0047] Through the above technical solution, 1. The discharge component 5 enables intermittent conveying of waste plastic bottles, preventing them from accumulating on the conveying component 2 due to excessive conveying. Furthermore, the control component 7 can change the conveying volume of the discharge component 5 each time, allowing for application in more conveying scenarios and improving practicality. The blocking component 8 spreads out the waste plastic bottles on the conveying component 2, further preventing accumulation and facilitating sorting by workers. Thus, this device prevents the accumulation of waste plastic bottles on the conveying component 2, eliminating the need for manual separation, saving time and effort, and improving sorting efficiency; 2. The screw 26 and nut 27 can fix the position of the blocking plate 23, making... The device can stably spread out the accumulated waste plastic bottles. When the size of the waste plastic bottles changes, the position of the baffle plate 23 can be removed by rotating the nut 27, thereby manually moving the baffle plate 23 to slide in its positioning groove 22, causing the screw 26 to slide in its fixing groove 24. When the reserved height below the baffle plate 23 matches the size of the waste plastic bottle, the position of the baffle plate 23 can be fixed again by the nut 27. This avoids the problem of the waste plastic bottles being blocked by the baffle plate 23 due to changes in size and no longer being transported normally on the conveying assembly 2. The device can adapt to waste plastic bottles of different sizes for sorting operations, spreading them out on the conveying assembly 2 for easy sorting by workers.
