DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-5 This application is described in further detail.

[0027] Example 1 of the present application discloses an intelligent classifier for restaurant waste using the Clean Plate Action.

[0028] Reference Figure 1 , the intelligent sorting machine for catering garbage of the "Clear Plate Action" comprises a box body 1, a garbage can 2 and an identification device. A recycling platform is provided on the top of the box body 1, and a recycling port 3 is provided on the recycling platform. The garbage can 2 is placed in the box body 1 and is located below the recycling port 3. The identification device is used to obtain the personal identity information of the diners at the garbage recycling site and the recycled plate information and communicate with the host computer. The recycled plate information at least includes the remaining weight of the dishes and the remaining type of the dishes. A multi-station switching mechanism is provided in the box body 1, and the multi-station switching mechanism includes a horizontal electric rotating table 4, a vertical electric rotating table 5 and a turnover barrel 6. A plurality of vertical electric rotating tables 5 are distributed circumferentially on the horizontal electric rotating table 4. The vertical electric rotating table 5 is fixedly connected to a horizontal mounting plate 7. The turnover barrel 6 is fixedly installed on the upper and lower sides of the horizontal mounting plate 7. A weighing module 8 is provided between the horizontal mounting plate 7 and the turnover barrel 6. The number and position of the recycling port 3, the horizontal mounting plate 7 and the garbage can 2 correspond to each other one by one. The horizontal electric rotating table 4, the vertical electric rotating table 5 and the weighing device are all electrically connected to the identification device.

[0029] Working principle: The intelligent sorting machine for catering waste in the "Clean Plate Campaign" is an efficient catering waste recycling and sorting system. It realizes the intelligent management and recycling of catering waste by integrating key components such as the box 1, the trash can 2, the recycling platform, the recycling port 3, the identification device, and the multi-station switching mechanism. The recycling platform on the top of the box 1 is provided with a recycling port 3 for receiving the plate waste thrown in by diners. Different recycling type names can be marked on the recycling port 3 to guide users to place the waste. The trash can 2 is located in the box 1, corresponding to the recycling port 3 below, for collecting garbage.

[0030] The identification device can obtain the personal identity information of the diner and can also identify the information of the recycled plate, including the remaining weight and type of the dishes. For easy operation, the plate consists of a tray and multiple plates. The tray can weigh the total weight of the tableware and dishes. The remaining weight of the dishes is obtained by calculating the difference between the total weight weighed at the serving window and the recycling place.

[0031] The dishes are marked with different shapes or patterns to facilitate image recognition by cameras or barcode scanners, so as to quickly obtain information such as the name and type of the corresponding dishes. This information is crucial for analyzing diners' dining habits and waste. The multi-station switching mechanism inside the box 1 is composed of a horizontal electric rotating table 4, a vertical electric rotating table 5 and a turnover barrel 6, which realizes automatic classification and storage of garbage.

[0032] A plurality of vertical electric rotating tables 5 are distributed on the horizontal electric rotating table 4, each vertical electric rotating table 5 is fixedly connected with a horizontal mounting plate 7, and turnover barrels 6 are installed on the upper and lower sides of the horizontal mounting plate 7 for temporarily storing garbage of different types or weights.

[0033] Taking two workstations as an example, the upper turnover barrel 6 receives the garbage dropped from the recycling port 3. If the garbage type is placed correctly, the vertical electric rotating table 5 drives the horizontal mounting plate 7 to flip 180 degrees, so that the upper and lower turnover barrels 6 move and switch, and dump the garbage into the corresponding garbage can 2 below. If the garbage type is placed incorrectly, the horizontal electric rotating table 4 rotates 180 degrees, so that the left and right turnover barrels 6 move and switch, and then the vertical electric rotating table 5 flips 180 degrees to dump the garbage into the correctly corresponding garbage can 2.

[0034] In addition, a weighing module 8 is provided between the horizontal mounting plate 7 and the turnover barrel 6, which is used to monitor the weight of garbage put into the recycling port 3 of different recycling types in real time to ensure the correct classification and storage of garbage. The number and position of the recycling port 3, the horizontal mounting plate 7 and the garbage bin 2 correspond one to one, ensuring the accuracy of garbage delivery. All the above structures are electrically connected to the identification device, ensuring the coordinated operation of the entire system and the real-time transmission of data.

[0035] The intelligent classifier for restaurant waste in the "Clean Plate Campaign" adopts an intelligent design, which not only improves the efficiency of waste recycling, but also provides personalized waste analysis and feedback to diners, thereby promoting the rational use and conservation of restaurant resources. At the same time, the solution can also correct errors in the process of separating garbage and ensure the accuracy of garbage classification, providing strong support for the "Clean Plate Campaign" and environmental protection.

[0036] In order to improve the weighing effect and the garbage dumping effect, the left and right sides of the turnover barrel 6 are provided with vertical slide grooves 9, and a vertical slider 10 is slidably installed in the vertical slide grooves 9. The vertical slider 10 is fixedly connected to the clamping claw rod 11. The lower end of the clamping claw rod 11 is hinged to the horizontal mounting plate 7. An elastic connecting rod 12 for resetting is hinged between the middle part of the clamping claw rod 11 and the horizontal mounting plate 7. The function of the elastic connecting rod 12 is to automatically reset the clamping claw rod to the original state after the clamping action is completed, and keep the vertical slider 10 sliding in the vertical slide groove 9. A weighing plate 13 is provided in the middle part of the horizontal mounting plate 7, and the weighing module 8 is installed on the load-bearing plate. In order to further reduce friction, rollers are preferably installed on the inner side of the vertical slider 10.

[0037] Through the above technical solution, the structure of the turnover bucket 6 is optimized to improve the accuracy of weighing and the efficiency of garbage disposal. The left and right sides of the turnover bucket 6 are equipped with vertical slide grooves 9, and the vertical slide grooves 9 are equipped with slidable vertical sliders 10, so that the turnover bucket 6 and the clamping claw rod 11 form a floating connection, so that the weighing module 8 can accurately measure and record the weight of the garbage, and provide accurate data for the system to analyze the food waste of diners.

[0038] When the turnover barrel 6 is turned over to the bottom, the turnover barrel 6 can follow the free fall of the garbage for a distance and then use inertia and kinetic energy to shake out the garbage, ensuring that the garbage can be poured out of the turnover barrel 6 smoothly, thereby improving the efficiency and reliability of the entire garbage recycling process. When the turnover barrel 6 needs to be replaced, it is only necessary to open the clamping claws 11 on both sides to separate the vertical slide groove 9 and the vertical slide block 10.

[0039] As attached Figure 3-4 As shown, Example 2: The difference from Example 1 is that a shock-absorbing seat 14 is provided on the horizontal mounting plate 7, a mounting hole is provided in the middle of the shock-absorbing seat 14, a through-type push-pull electromagnet 15 is fixedly installed on the mounting hole, and the through-type push-pull electromagnet 15 includes an electromagnetic coil, a reset spring and an iron core, and shock-absorbing support feet are provided at the upper and lower ends of the iron core.

[0040] In order to improve the stability of the equipment and reduce vibration during operation, a shock-absorbing seat 14 is specially provided on the horizontal mounting plate 7. The shock-absorbing seat 14 is designed to absorb and isolate the impact and vibration that may be generated during the garbage delivery process, thereby protecting the accuracy of the weighing module 8 and extending the service life of the equipment.

[0041] The through-type push-pull electromagnet 15 is used to assist in realizing the shock-absorbing function of dumping garbage. The electromagnetic coil is responsible for generating electromagnetic force to drive the movement of the iron core; the reset spring pulls the iron core back to the initial position when the electromagnet is powered off to ensure that the mechanism can be quickly reset; the iron core serves as the moving part of the electromagnet, and its upper and lower ends are equipped with shock-absorbing support feet, which not only increases the stability of the electromagnet, but also helps to reduce the impact and vibration during direct contact.

[0042] The through-type push-pull electromagnet 15 can be extended in advance to prop up the upper turnover barrel 6, and the impact force of the garbage thrown into the turnover barrel 6 is transferred to the shock-absorbing seat 14. Then the through-type push-pull electromagnet 15 is powered off and reset, and the turnover barrel 6 is placed on the weighing module 8 for weighing. After weighing, it is propped up again to prevent the turnover barrel 6 from flipping over and affecting the measurement accuracy and life of the weighing module 8.

[0043] In order to reduce the number of weighing modules 8, reduce the use cost and ensure the consistency of measurement, the middle part of the horizontal mounting plate 7 has a hollow hole, one side of the hollow hole is provided with an axis hole, a horizontal axis 16 is provided in the axis hole, one end of the horizontal axis 16 is fixedly connected to the weighing plate 13, and the other end of the horizontal axis 16 is fixedly connected to the horizontal electric rotating table 4. The weighing plate 13 can be used as a center point, and the other end of the horizontal axis 16 is fixedly connected to the horizontal electric rotating table 4, which is kept fixed by the horizontal axis 16 and will not flip vertically, so that the weighing module 8 can serve two different turnover barrels 6 above and below.

[0044] The movement of the horizontal electric rotating table 4 can drive the horizontal shaft 16 to rotate horizontally, thereby keeping the horizontal positions of the weighing module 8 and the turnover barrel consistent. The above design not only reduces the number of weighing modules 8 and reduces the cost of the equipment, but also ensures the consistency of the measurement results by sharing one weighing module 8 to weigh the contents of the upper and lower turnover barrels 6.

[0045] In addition, since the weighing module 8 does not need to be installed separately for each turnover barrel 6, this also simplifies the maintenance and calibration of the equipment and improves the operating efficiency and reliability of the entire intelligent sorting machine.

[0046] As attached Figure 5 As shown, Example 3: The difference from Example 1 is that, in order to ensure the orderly entry of garbage, a feed hopper 17 is provided on the recycling port 3, and a feed valve is provided at the bottom of the feed hopper 17. The feed valve includes a valve plate 18 and a linear drive module 19. The linear drive module 19 is arranged between the valve plate 18 and the box body 1. The valve plate 18 is a key component for controlling the garbage to enter the interior of the box body 1 from the feed hopper 17. The linear drive module 19 can drive the valve plate 18 to perform linear motion to open or close.

[0047] Some restaurants offer free soup, and when these soups are mixed with the food residue and poured in together, it will affect the weighing results. When the weight of the soup does not need to be counted, a filter cavity 20 is provided on the valve plate 18, and a filter plate 21 is provided on the filter cavity 20. The filter cavity 20 is connected to the liquid collecting tank 22 through a pipeline, and a rinse pipe 23 is provided on the top of the feed hopper 17, and the rinse pipe 23 is connected to the automatic water spray system. The filter cavity 20 is an area specially used to separate the liquid and solid parts in the garbage. The filter plate 21 on the filter cavity 20 is to further ensure that only solid garbage enters the box body 1, while the liquid is separated and guided to the liquid collecting tank 22. The filter cavity 20 is connected to the liquid collecting tank 22 through a pipeline, so that the liquid part of the garbage can be effectively collected and processed.

[0048] In order to keep the recovery port 3 and the feed hopper 17 clean, a rinse pipe 23 is also provided on the top of the feed hopper 17. The rinse pipe 23 is connected to an automatic water spraying system, which can automatically clean the recovery port 3 and the feed hopper 17 when necessary to keep the equipment clean and reduce the generation of odor.

[0049] This design not only improves the efficiency and accuracy of waste collection, but also improves the cleanliness and maintenance convenience of the equipment through liquid separation and automatic cleaning functions. Through these meticulous designs, the Clean Plate Campaign catering waste intelligent sorting machine can optimize services for the Clean Plate Campaign, promote the environmentally friendly treatment of catering waste and the rational use of resources.

[0050] In order to solve the pollution problem that may be caused by the turnover barrel in the box after the trash can is vacated, a water collection tank 24 is provided at the bottom of the box body 1, and a grid plate is designed on the top of the water collection tank 24 to support the trash can. A sewage pump 25 is provided at the bottom of the water collection tank 24, and the sewage pump 25 is connected to the liquid collection box 22. The function of the water collection tank 24 is to collect liquid that may drip or overflow during the garbage collection and pouring process, so as to prevent these liquids from accumulating in the box body and causing secondary pollution. The sewage pump 25 is used to discharge the collected liquid from the water collection tank 24 and transport it to the liquid collection box 22.

[0051] The liquid collecting box 22 can be a storage container for temporarily storing the collected liquids for subsequent processing or discharge. Through the above-mentioned design, the CD Action catering garbage intelligent sorting machine can not only effectively process solid waste, but also properly manage liquid waste to prevent pollution and odor in the box. This garbage disposal solution helps to maintain the cleanliness and hygiene of the equipment and the surrounding environment, and also improves the efficiency of the equipment and the user experience.

[0052] In order to automatically clean the turnover barrel, a nozzle 26 is provided in the water collection tank 24, and the nozzle 26 is connected to the automatic water spraying system. The nozzle 26 is located directly below the turnover barrel 6. When cleaning is required, the automatic water spraying system will be started, and the nozzle 26 will then spray water to rinse the inside of the turnover barrel 6. This automated cleaning method not only saves water resources, but also improves the uniformity and thoroughness of cleaning. The sewage and residual liquid after cleaning will flow down the inner wall of the turnover barrel 6 and finally gather in the water collection tank 24.

[0053] In addition, the design of the identification device includes a communication host, a card reader 27, a weighing instrument 28 and an identification camera. The card reader 27, the weighing instrument 28 and the identification camera 30 are electrically connected to the communication host. The identification device integrates multiple functions. It works in coordination with the communication host, the card reader 27, the weighing instrument 28 and the identification camera to realize the identification of the diner, the weighing of the dishes and the photographing and recording of the dishes.

[0054] Card reader 27: A device for reading the IC card of a diner, through which the personal identity information of the diner can be obtained. The information read by the card reader 27 is then sent to the communication host for further processing and recording.

[0055] Weighing instrument 28: This device is responsible for measuring the remaining weight of the dishes in the returned plate to assess whether the diner has achieved the "Clean Plate Action". The data obtained by the weighing instrument 28 will also be transmitted to the communication host.

[0056] Identification camera 30: It is not only used for face recognition to verify the identity of the diner, but also used to take pictures of the plate and the remaining dishes. These pictures can be used for subsequent image recognition and analysis to more accurately assess the type of dishes and the remaining amount.

[0057] Communication host: As the processor of the identification device, the communication host is responsible for receiving data from the card reader 27, weighing instrument 28 and identification camera, and processing this information. The communication host is also responsible for data communication with the host computer and uploading the collected data to the central management system for data aggregation, analysis and recording.

[0058] The recognition device also includes a voice guidance module 31 connected to the communication host and a touch screen 29. The voice guidance module 31 is connected to the communication host to realize voice interaction between the device and the user. This module can provide operation guidance, feedback information or answer questions, enhance user experience, and make operation more intuitive and convenient.

[0059] Touch screen 29: provides an intuitive interface for users. Through the touch screen, users can perform various settings and operations, such as viewing weighing results, personal CD credit information, and can also interact with the system through the touch screen.

[0060] Through the collaborative work of the above components, the identification device not only improves the intelligence level of the restaurant waste intelligent sorting machine, but also enhances the user interaction experience, making the entire waste recycling process more efficient, accurate and user-friendly. This design helps promote the implementation of the "Clean Plate" campaign and reduce food waste, while also providing diners with a high-tech interactive platform.

[0061] In order to improve the quality of catering services and the profitability of operators through intelligent data analysis, the intelligent sorting machine for catering waste in the Clean Plate Campaign provided by this application can add the following functional modules: (1) Customer preference analysis function: By collecting information about diners’ frequency of choosing dishes, the amount of dishes left over, and feedback after meals, data mining technology is used to analyze customers’ dining preferences and provide restaurants with customer preference reports.

[0085] The recognition device in the Clean Plate Campaign restaurant waste intelligent sorting machine, especially the camera. The camera can identify the remaining dishes on the plate, including the type and weight of the dishes, through image recognition technology. This recognition technology usually involves machine learning and deep learning algorithms, which enable the camera to recognize different objects and materials.

[0086] In a smart garbage collection machine, the working principle of the camera usually includes the following steps: Image capture: The camera captures the image of the remaining food on the plate or the image of the food on the plate in real time.

[0087] Image preprocessing: Process the captured images, such as adjusting brightness, contrast, and cropping, to improve recognition accuracy.

[0088] Feature extraction: Algorithms are used to extract key features from images that can represent the type and state of the dish.

[0089] Classification and recognition: Use the trained classification model to classify and recognize dishes based on the extracted features.

[0090] Data recording: The recognition results will be recorded and uploaded to the host computer or central management system together with the user's personal identity information.

[0091] Feedback output: The system may provide feedback based on the recognition results. For example, if the user puts in the wrong type of garbage, the system can prompt the user through a display or voice.

[0092] In addition, in the "Clean Plate Campaign" restaurant waste smart sorting machine, we can expand the camera's function into a more comprehensive evaluation system that can not only identify plates and dishes, but also evaluate the accuracy and effectiveness of consumers' waste sorting and give rewards accordingly.

[0093] The functions of the evaluation system include the following: 1. Visual evaluation and classification guidance: The evaluation system uses advanced image recognition technology, integrated camera modules, and deep learning algorithms such as convolutional neural networks (CNN) to improve the accuracy of identifying different types of garbage. It can not only identify plates and dishes, but also determine whether consumers have correctly classified garbage into vegetable, fruit, staple food, and protein categories as required. The system provides real-time feedback and guides diners on how to correctly classify through speakers or displays to improve the accuracy of garbage classification.

[0094] 2. Classification effect scoring: The evaluation system automatically gives a score based on the accuracy and effectiveness of garbage classification. The score information can be sent to the user's personal smart terminal to encourage or supervise the diners' dining behavior. This scoring system can set different standards, such as classification completeness, cleanliness, etc. The score can be quantitative, such as from 0 to 100 points, or a rating based on specific standards, such as excellent, good, qualified, etc.

[0095] 3. Carbon emission reduction points reward: According to the consumer's classification effect score, the system can give corresponding carbon reduction points as rewards. This reward mechanism encourages consumers to participate more actively in garbage classification and reduce food waste. Carbon reduction points can be used to redeem restaurant coupons, small gifts or other incentives to increase consumer participation.

[0096] 4. Contribution: The evaluation system can calculate the contribution of each correct garbage sorting to reducing carbon emissions. This can be achieved by estimating the amount of food waste reduced and the corresponding carbon footprint. The system can show individual and collective carbon reduction results and increase consumer awareness and participation in environmental protection. The system analyzes consumer behavior through machine learning models and continuously optimizes the classification guidance and scoring system.

[0097] 5. Data recording and analysis: The evaluation system records detailed data for each classification, including classification type, weight, time and score. These data can be used to analyze consumer behavior patterns, optimize garbage classification guidance strategies, and improve the overall garbage classification effect. The system can be integrated with a data encryption module to ensure that all collected data complies with data protection regulations and protect consumer privacy.

[0098] 6. Education and publicity: The evaluation system can integrate an education module to provide knowledge and skills on waste sorting, helping consumers better understand and implement waste sorting.
