Description

Technical Field

[0001] This invention relates to the field of recycling technology, and in particular to a device for recycling and processing waste plastic bottles. Background Technology

[0002] The field of plastic recycling technology encompasses the research and application of complete processes and supporting treatment equipment for the classification, collection, crushing, washing, sorting, separation, melting, recycling, and modification of waste plastics. This technology focuses on reducing the pollution of the natural environment by plastic waste and increasing the recycling rate of waste plastic resources. It covers the recycling and treatment of various types of waste plastics, including consumer plastics, industrial plastics, and food packaging plastics. It adapts corresponding treatment processes and hardware devices to waste plastics of different materials, pollution levels, and forms, connecting the front-end waste collection and transportation system with the back-end recycled material processing and application stages. It is an important component of the field of solid waste resource utilization and ecological environmental protection.

[0003] Chinese Patent Publication No. CN120245270A discloses a waste recycling and processing device for processing plastic bottles, including a box body. A conveyor belt is provided on one side of the box body, and an active roller is provided at one end of the conveyor belt. This waste recycling and processing device for processing plastic bottles uses the conveyor belt to transport plastic bottles into the box body for processing, saving manpower. During the transportation process, a cleaning structure pre-washes the surface of the plastic bottles to remove surface dust and prevent dust from flying and polluting the environment during crushing. The crushed plastic particles are sprayed with clean water through a first water outlet, and then the plastic particles are turned over by an arc-shaped stirring plate to ensure that the plastic particles are cleaned evenly. Since the surface of the arc-shaped stirring plate is provided with a first brush, it can sweep away dust from the surface of the plastic particles. Through two cleanings of the plastic waste, the cleaning efficiency is improved, thereby ensuring the quality of the plastic waste and improving the recycling rate. However, the above solution still has the following defects:

[0004] The above solution only uses a conveyor belt to transport plastic bottles and perform preliminary surface washing. After crushing, the plastic particles are stirred and washed. It cannot separate lightweight label impurities in advance after the crushing process. Labels mixed into the crushed material will increase the processing load of the washing process. Stirring and washing alone cannot achieve precise separation of bottle body and cap debris. The material conveying process lacks a precise guiding design, which can easily lead to material jamming and accumulation. There is no synchronous linkage structure between the various processing steps, the manual operation intensity is high, the purity of material recovery is difficult to guarantee consistently, and the continuity of the equipment processing flow is insufficient. Summary of the Invention

[0005] The main objective of this invention is to provide a plastic bottle waste recycling and processing device that can effectively solve the problems mentioned in the background art.

When a large number of labels are attached to the surface of the sieve gap baffle, the sieve gap baffle will drive the rotating rod to rotate. A collection bucket is slidably connected to the inner cavity of the fixed shell, and two handles are provided at the rear of the collection bucket.

[0013] Preferably, when the rotating rod rotates, since the front part is fixedly connected to the transmission wheel, the transmission belt connected to the outer surface of the transmission wheel will drive the feeder to rotate. After the screen gap baffle rotates to the appropriate position, the left side of the mating plate will cooperate with the screen gap baffle to remove the label on the surface of the screen gap baffle.

[0020] 2. Through the cooperation of the guide component and the outer shell, the crushed plastic fragments are precisely guided and conveyed, avoiding material jamming, accumulation, and waste, and ensuring the continuity of the material processing flow. Through the cooperation of the electric fan and the screen baffle of the separation mechanism, the plastic fragments and lightweight labels are efficiently separated, improving the purity of the recycled materials. Through the linkage of the drive wheel and drive belt of the separation mechanism and the feeder of the collection mechanism, the label rejection and conveying are synchronized, reducing the intensity of manual operation.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1, please refer to Figure 1 , Figure 2 ,as well as Figure 3As shown, a plastic bottle waste recycling and processing device includes four support legs 1, which provide stable load-bearing support for the entire device, effectively dispersing the vibration generated during the operation of the device and ensuring the stability of the operation of each mechanism. The upper ends of the four support legs 1 are fixedly connected to a box body 2, which provides a closed and stable processing space for the label separation, cleaning, and bottle body and cap separation processes of plastic bottle waste. A transfer component 3 is fixedly connected to the left side of the box body 2, which is used to stably transfer the plastic bottle body fragments that have completed the entire process to a designated storage or reprocessing location. A crushing mechanism 4 is set on the top of the box body 2, which is used to pre-crush the input plastic bottle waste, breaking the whole plastic bottle into uniformly sized fragments, providing a processing basis for the subsequent separation and cleaning processes. A collection mechanism 5 is fixedly connected to the rear of the box body 2, which is used to collect and store the separated plastic bottle labels for easy cleaning by staff.

[0035] The crushing mechanism 4 includes a second outer shell 41, which provides a closed working space for the crushing process of plastic bottle waste. This effectively prevents plastic fragments from splashing outwards during crushing, ensuring a clean working environment and operator safety. Guide blocks 42 are fixedly connected to the left and right sides of the inner cavity of the second outer shell 41. These guide blocks 42 precisely guide the input plastic bottle waste, guiding it smoothly into the meshing working area of ​​the two crushing wheels 43, preventing waste from getting stuck at the inlet and affecting overall processing efficiency. Two symmetrically arranged crushing wheels are rotatably connected to the bottom of the second outer shell 41. The crushing wheels 43, two symmetrically arranged, ensure uniform crushing force, breaking the plastic bottle into uniformly sized fragments, effectively improving the processing effect of subsequent separation and cleaning processes. A storage box 44 is fixedly connected to the rear of the outer casing 41. The storage box 44 contains a gearbox and a power source, which are used to drive the two crushing wheels 43 to crush the plastic bottle. At the same time, the storage box 44 can provide good protection for the built-in gearbox and power source, preventing dust generated during the crushing process and wastewater generated in subsequent processes from entering the interior and causing damage to the components, effectively extending the service life of the power mechanism.

[0036] Furthermore, the housing 2 includes an outer shell 21, which provides a closed working chamber for the entire process of label separation, cleaning, and bottle body and cap separation after the plastic bottle waste is crushed. This effectively prevents wastewater overflow and debris scattering during the process, ensuring cleanliness and smooth operation. Several electric fans 22 are installed on the right side of the outer shell 21, each equipped with a power supply to start. The built-in power supply ensures continuous and stable operation of the electric fans 22, providing stable airflow for the label separation process. A guide component 23 is fixedly connected to the top of the inner cavity of the outer shell 21. The guide component 23 accurately guides the crushed plastic debris, guiding it smoothly into the subsequent processing station and preventing debris from accumulating on the top of the outer shell 21 and affecting the overall processing progress. The guide component 23 has an outer surface... A separation mechanism 24 is wound around the left side of the outer shell 21. The separation mechanism 24 is used to work with the airflow generated by the electric fan 22 to separate plastic fragments from lightweight labels. A centrifugal mechanism 26 is fixedly connected to the bottom right side of the outer shell 21. The centrifugal mechanism 26 is used to fully stir the water in the inner cavity of the outer shell 21, so that the plastic fragments and water can fully contact each other to complete the cleaning operation, while accelerating the separation speed of water and fragments. A separation mechanism 25 is fixedly connected to the left side of the centrifugal mechanism 26. The separation mechanism 25 is used to separate the plastic bottle body and plastic cap fragments after cleaning, so as to realize the classified recycling of bottle body and cap and improve the utilization rate of recycled resources. Several drying components are set on the left side of the inner cavity of the outer shell 21. The drying components only need to heat and blow air on the crushed plastic bottle body and cap. The specifics are subject to actual production.

[0037] The support leg 1 and the outer shell 21 of the housing 2 provide a stable load-bearing and enclosed processing space for the device. The outer shell 41, guide block 42, crushing wheel 43 and the collection box 44 of the crushing mechanism 4 are used to achieve uniform crushing of plastic bottle waste and protection of the power components. The electric fan 22, guide component 23 and separation mechanism 24 are used to achieve efficient separation of labels and plastic fragments. The centrifugal mechanism 26 and separation mechanism 25 are used to clean plastic fragments and accurately separate bottle body and cap. The transfer component 3 and the collection mechanism 5 are used to achieve stable transfer and collection of processed materials and separated labels. The whole process realizes integrated processing of plastic bottle recycling, improves recycling efficiency and resource utilization, and reduces manual operation intensity and equipment operation wear.

[0038] Example 2 further demonstrates how to separate the label from the surface of the plastic bottle, building upon Example 1. For further details, please refer to [link / reference needed]. Figure 4 and Figure 5As shown, the guiding component 23 includes a guide plate 231, which assists in the smooth sliding of crushed plastic fragments, preventing them from getting stuck or accumulating, and ensuring the continuity of material conveying. A mating plate 233 is fixedly connected to one side of the guide plate 231. The mating plate 233 provides a support for the rotation of the subsequent feeder 54, ensuring the stability of the label conveying process. It can also work with the separation mechanism 24 to remove labels. A guide block 232 is fixedly connected to one side of the mating plate 233. The guide block 232 is used to guide the crushed plastic bottle body and plastic cap fragments, accurately guiding the fragments to the processing station on the left side of the outer casing 21, preventing the fragments from scattering into non-working areas. When the plastic bottle body and plastic cap fragments fall, they will first land on the surface of the guide block 232 and slide into the left side of the outer casing 21, ensuring that all crushed materials can enter the preset processing flow and avoiding material waste.

[0039] Furthermore, the separation mechanism 24 includes a rotating rod 241, which is rotatably connected to the inner cavity of the outer shell 21. The rotation process is smooth and stable, providing stable transmission support for the rotation of the screen baffles 242. Several screen baffles 242 are fixedly connected to the outer surface of the rotating rod 241. The screen baffles 242 can effectively intercept lightweight labels blown by the electric fan 22, while allowing small plastic fragments to continue falling through the screen gaps, avoiding the mixing of labels and plastic fragments and affecting the purity of subsequent recycling. A transmission wheel 243 is fixedly connected to the front of the rotating rod 241. The transmission wheel 243 can rotate synchronously with the rotating rod 241, stably outputting rotational power. A transmission belt 244 is wound around the outer surface of the transmission wheel 243. The transmission belt 244 can synchronously transmit the rotational power of the transmission wheel 243 to the feeder 54 of the collection mechanism 5, realizing the synchronous linkage of label interception and label conveying, and improving the coordination of device operation.

[0040] Furthermore, the collection mechanism 5 includes a fixed housing 51, which protects and positions the built-in collection bin 52, preventing labels from scattering during collection and ensuring the cleanliness of the collection operation. A feeder 54 is rotatably connected to the front of the fixed housing 51. The feeder 54 is in close contact with the inner surface of the mating plate 233, ensuring that the labels removed by the mating plate 233 are smoothly scraped off and conveyed, avoiding label residue or jamming. When the plastic bottle body and cap are crushed, since the crushed labels are lighter than the plastic itself, the labels on their surface will be removed by several electric fans 2. 2. The labels are blown onto the surface of the screen baffle 242, achieving initial separation of the labels from the plastic debris. When a large number of labels are applied to the surface of the screen baffle 242, the weight of the labels will drive the screen baffle 242 and the rotating rod 241 to rotate synchronously, providing power for subsequent label removal and conveying. A collection bucket 52 is slidably connected to the inner cavity of the fixed shell 51. The collection bucket 52 is used to collect the separated labels. Two handles 53 are provided at the rear of the collection bucket 52. The two handles 53 make it convenient for the staff to regularly remove the collection bucket 52 from the fixed shell 51 for cleaning, improving the convenience of device maintenance.

[0041] When the rotating rod 241 rotates, since the front part of the rotating rod 241 is fixedly connected to the transmission wheel 243, the rotating rod 241 will drive the transmission wheel 243 to rotate synchronously. The transmission belt 244, which is connected to the outer surface of the transmission wheel 243, will then drive the feeder 54 to rotate synchronously, realizing the coordinated operation of the label rejection action and the label conveying action, avoiding the accumulation of labels. After the screen gap baffle 242 rotates to the appropriate position, the left side of the mating plate 233 will cooperate with the screen gap baffle 242 to completely remove the labels attached to the surface of the screen gap baffle 242, avoiding label residue from affecting the subsequent label separation effect. After the labels are removed, they will slide to the feeder 54, and then enter the inner cavity of the collection bucket 52 for centralized collection through the spiral conveying action of the feeder 54. This realizes fully automated label separation and collection, effectively reducing the intensity of manual operation.

[0042] By cooperating with the guide component 23 and the outer shell 21, the crushed plastic fragments are precisely guided and conveyed, avoiding material jamming, accumulation, and waste, and ensuring the continuity of the material processing flow. By cooperating with the electric fan 22 and the screen baffle 242 of the separation mechanism 24, the plastic fragments and lightweight labels are efficiently separated, improving the purity of the recycled materials. By cooperating with the drive wheel 243 and drive belt 244 of the separation mechanism 24 and the feeder 54 of the collection mechanism 5, the label rejection and conveying are synchronized, reducing the intensity of manual operation. By cooperating with the collection bucket 52 of the collection mechanism 5 and the fixed shell 51, the separated labels are centrally collected, ensuring the cleanliness of the operation and the convenience of equipment maintenance.

[0043] Example 3 further achieves the separation of the plastic bottle body and the plastic bottle cap based on Examples 1 and 2. For further details, please refer to [link / reference]. Figure 6 , Figure 7 , Figure 8 as well as Figure 9 As shown, the separation mechanism 25 includes a guide block 251, which guides the cleaned plastic debris precisely into the transfer bucket 252, preventing debris from scattering into non-working areas and ensuring the accuracy of material conveying. The transfer bucket 252 is fixedly connected to the upper end of the guide block 251. The transfer bucket 252 provides a stable working space for the upward conveying of plastic bottle debris and the separation of bottle body and cap. A transmission rod 253 is rotatably connected to the inner cavity of the transfer bucket 252. The transmission rod 253 provides stable transmission support for the rotation of the spiral feed plate 255, driving the spiral feed plate 255 to rotate synchronously. A separation rod 254 is fixedly connected to the upper part of the guide block 251. The separating rod 254 is used to scrape off the crushed bottle cap fragments. It can effectively scrape off the bottle cap fragments floating or mixed in with the plastic bottle body fragments, and achieve precise separation of the bottle body and bottle cap fragments. This facilitates subsequent classification and recycling, effectively improving recycling efficiency and resource utilization. The upper end of the transmission rod 253 is fixedly connected to the spiral feeding plate 255. The spiral feeding plate 255, in cooperation with the guide block 251, separates the plastic bottle body that has sunk to the bottom. It can stably transport the plastic bottle body fragments that have sunk to the bottom after cleaning upwards, completing the separation of bottle body fragments from water and bottle cap fragments. The right side of the guide block 251 is movably connected and controlled by the control end at the front of 21.

[0044] Furthermore, the spiral feed plate 255 includes a guide rod 2551, which is fixedly connected to the transmission rod 253 and can rotate synchronously with the transmission rod 253, providing fixed support for the spiral plate 2552 and ensuring the stability of the spiral plate 2552 during rotation. The spiral plate 2552 is fixedly connected to the outer surface of the guide rod 2551. The spiral plate 2552 can push the bottomed plastic bottle fragments upward during rotation, realizing the stable transfer of bottle fragments. Several drainage holes 2553 are opened on the outer surface of the spiral plate 2552. The drainage holes 2553 can drain the moisture carried on the surface of the plastic fragments in time during the upward transfer of bottle fragments, realizing the secondary separation of fragments and moisture, effectively improving the dryness of the plastic fragments during subsequent transfer, and providing convenience for subsequent storage and reprocessing.

[0045] Furthermore, the centrifugal mechanism 26 includes a receiving plate 261, which can receive plastic fragments that fall after label separation and guide them smoothly into the water washing area. A fixing column 264 is fixedly connected to the bottom of the receiving plate 261, providing stable support and effectively preventing displacement or deformation of the receiving plate 261 under the impact of material and water disturbance, ensuring the stability of the receiving operation. Power columns 263 are rotatably connected to the front and rear sides of the receiving plate 261. The two power columns 263 provide stable transmission support for the rotation of the turbulence belt 262. The turbulence belt 262 is wound around the outer surfaces of the two power columns 263. The turbulence belt 262 is used to agitate the water inside the outer shell 21, ensuring that the plastic fragments come into full contact with the water during rotation, thoroughly cleaning away stains and residual impurities from the surface of the fragments. To effectively improve the purity of recycled plastic scrap and accelerate the separation of water and scrap, a transmission belt 265 is wound around the bottom of the two power columns 263 and the bottom of the transmission rod 253. The transmission belt 265 can synchronously transmit the rotational power of the rear power column 263 to the front power column 263 and the transmission rod 253, realizing the synchronous linkage of the cleaning and stirring process and the bottle body and cap separation process, improving the coordination and processing efficiency of the device. A motor 266 is fixedly connected to the bottom of the rear power column 263. The motor 266 provides the core power for the operation of the centrifugal mechanism 26 and the separation mechanism 25. A fixing plate 267 is fixedly connected to the bottom of the motor 266. The fixing plate 267 is fixedly connected to the right rear support leg 1, which can firmly fix the motor 266 and effectively reduce the vibration generated by the motor 266 during operation, ensuring the stability of the device operation.

[0046] The simultaneous cleaning and precise separation of plastic debris is achieved through the cooperation of separation mechanism 25 and centrifugal mechanism 26. The guide block 251 ensures the accuracy of material conveying. The separation rod 254 achieves precise separation of bottle body and cap debris. The spiral feed plate 255 achieves stable conveying of bottle body debris and secondary moisture separation. The turbulence belt 262 of centrifugal mechanism 26 achieves thorough cleaning of plastic debris. The transmission belt 265 enables the synchronous linkage of the cleaning and separation processes, effectively improving the recycling purity of plastic debris and the processing efficiency of the device, and ensuring the stability and synergy of the device operation.

[0047] Example 4, based on Examples 1, 2, and 3, further achieves the purpose of transferring the separated bottle cap and bottle body. Please refer to [link / reference needed]. Figure 10As shown, the transfer assembly 3 includes a protective shell 31. One side of the protective shell 31 is fixedly connected to the left side of the outer shell 21. The protective shell 31 provides good protection for the built-in motor 32 and transmission components, preventing sewage and plastic debris from entering and damaging the components, and effectively extending the service life of the transmission components. The motor 32 is fixedly connected to one side of the protective shell 31. The motor 32 provides stable power output for the operation of the transfer assembly 3. A transmission roller is fixedly connected to the output end of the motor 32. The transmission roller can rotate synchronously with the output end of the motor 32, stably transmitting power to the conveyor belt 33. Two symmetrically arranged fixed legs 35 are fixedly connected to the bottom of the outer shell 21. The transmission roller is fixedly connected to the middle of the two fixed legs 35. The two fixed legs 35 transmit power to the transmission roller. The second moving roller provides stable support, ensuring the smoothness of the rotation of the second transmission roller. The outer surfaces of the first and second transmission rollers are connected together by a conveyor belt 33. The conveyor belt 33 can rotate stably under the drive of the first and second transmission rollers to complete the transfer of plastic fragments. A baffle plate 34 is fixedly connected to the outer surface of the conveyor belt 33. The baffle plate 34 is L-shaped and is used to transfer the crushed plastic bottle fragments. It can effectively prevent the plastic fragments from slipping during the transfer process, ensuring the stability of the transfer process and the integrity of the material. The outer surface of the conveyor belt 33 is hollowed out to drain the crushed material. It can drain the plastic fragments again during the transfer process, further reducing the moisture content of the fragments, which is convenient for subsequent storage and reprocessing.

[0048] The protective shell 31, in conjunction with the second motor 32, effectively protects the internal transmission components, preventing sewage and plastic debris from entering and damaging them, thus extending the service life of the transmission components. The combination of the second motor 32, the first and second transmission rollers, and the conveyor belt 33 provides stable power output for plastic debris transfer, ensuring smooth operation. The fixed leg 35, in conjunction with the second transmission roller, enhances the support stability of the transmission structure.
