Description

Technical Field

[0001] This utility model relates to the field of automated catering service technology, and in particular to an automatic tray recycling and sorting device for smart canteens. Background Technology

[0002] With the popularization of smart catering models, smart canteen systems have revolutionized the dining process through IoT technology. Diners can scan a code to bind their smart plates and freely select different dishes, with precise pricing based on weight. This satisfies diverse dietary needs while significantly reducing food waste through an on-demand meal system. Such systems require post-meal processing to possess sophisticated sorting capabilities to match the front-end intelligence, addressing the highly discrete combinations of tableware and trace amounts of residue resulting from personalized meal selection. This places higher demands on the sorting efficiency and hygiene control of traditional plate recycling equipment.

[0003] Currently, most commercial dining dish recycling equipment adopts a "manual pre-sorting + mechanical conveyor washing" operation mode. Diners need to manually put small utensils such as chopsticks and spoons into individual collection ports, and place large utensils such as bowls and plates on the conveyor belt. Leftover food must be emptied into a special trash can. The conveyor belt transports the utensils to a spray washing machine for batch processing. Some high-end equipment is equipped with a visual recognition module for monitoring the stacking status of utensils. This mode relies on manual initial sorting, which can meet basic cleaning needs, but the sorting granularity is limited by the standardization of operation.

[0004] The mandatory multi-step sorting process for diners can easily lead to mishandling of utensils during peak dining hours. Statistics show that about 12% of utensils breakage is caused by mechanical jamming due to sorting errors. Secondly, there is a risk of contact contamination during the food waste disposal process. Even though smart canteens reduce food waste by 57% through precise food retrieval, liquid sauces and other residues still cause 23% of users to report hand contamination issues. Utility Model Content

[0005] To overcome the drawbacks of relying on manual sorting, this utility model provides an automatic tray recycling and sorting device for smart canteens, aiming to solve the above-mentioned shortcomings.

[0006] An automatic tray recycling and sorting device for smart canteens includes a conveyor, a dishwasher, and a sorting rack. One end of the sorting rack is connected to the end of the conveyor, and the other end is located above the inlet of the dishwasher. A support frame is connected to the front of the conveyor and is located at the bottom of the sorting rack. A vibrating frame is slidably connected to the left end of the top plate of the support frame. Several guide rods connected to the bottom of the vibrating frame are fitted with return springs. A motor is installed on the front of the top plate of the support frame, and the output shaft of the motor is connected to a protruding rod. The protruding rod is pressed into the middle of the bottom surface of the vibrating frame. Both the top plate of the support frame and the right side of the vibrating frame have through holes. The through holes of the vibrating frame are filled with a perforated plate. A solid-liquid separation component for collecting food residue is provided at the bottom of the through holes of the support frame. A dishwashing machine is placed at the bottom right end of the support frame.

[0007] Optionally, the solid-liquid separation assembly includes a collection box located at the bottom of the filter plate, a frame snapped into the collection box, a filter screen connected in the middle of the frame, and a drain outlet in the collection box.

[0008] Optionally, the sorting rack has a discharge port at one end near the conveyor, and the sorting rack is connected to several parallel sorting rods. Only the rear end of the sorting rod is fixedly connected to the sorting rack, and the front end of the sorting rod is provided with a notch to the sorting rack. The width of the notch is less than the height of the bowl.

[0009] Optionally, a splash guard is provided between the support frame and the vibration frame. The splash guard is located at the bottom of the sluice plate and surrounds the through hole of the top plate of the support frame.

[0010] Optionally, the strainer is provided with a plurality of circular holes, the diameter of which is smaller than the width of the spoon, and the circular holes in each row of the strainer are staggered.

[0011] Optionally, support blocks are connected to both the left and right ends of the bottom of the collection box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through the linkage design of the conveyor and the sorting rack, the screening structure of the notch at the front end of the sorting rod allows bowls and tableware to slide into the dishwasher automatically, while small tableware and food scraps fall into the vibrating rack through the notch, replacing the traditional manual sorting action and reducing the complexity of operation.

[0014] 2. The high-frequency vibration generated by the periodic tapping of the motor-driven protruding rod by the vibrating frame, combined with the flow guiding characteristics of the misaligned circular holes of the slotted plate, enables the tableware and food residue to be automatically separated based on size differences, while realizing the directional separation of solid and liquid, eliminating the risk of hand contact when diners pour out food residue.

Detailed Implementation

[0020] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0021] Example: An automatic tray recycling and sorting device for smart canteens, such as... Figures 1-3 As shown, the system includes a conveyor 1, a dishwasher 2, a sorting rack 3, a support frame 4, a vibrating frame 5, a return spring 6, a motor 7, a protruding rod 8, a strainer 9, a dishwashing machine 11, and a solid-liquid separation assembly. The initial end of the conveyor 1 is used to place unprocessed plates. One end of the sorting rack 3 is connected to the end of the conveyor 1, and the other end of the sorting rack 3 is located above the inlet of the dishwasher 2. The end of the sorting rack 3 closest to the conveyor 1 has a discharge port, and the sorting rack 3 is connected to several parallel sorting rods. Only the rear end of each sorting rod is fixedly connected to the sorting rack 3, and the front end of each sorting rod has a notch in the sorting rack 3, the width of which is less than the height of the bowl. A support frame 4 is connected to the front of the conveyor 1 and is located at the bottom of the sorting rack 3. A vibrating frame 5 is slidably connected to the left end of the top plate. Several guide rods connected to the bottom of the vibrating frame 5 are fitted with return springs 6. The bottom of the return springs 6 is connected to the support frame 4, and the top of the return springs 6 is connected to the vibrating frame 5. A motor 7 is installed on the front side of the top plate of the support frame 4. The output shaft of the motor 7 is connected to a protruding rod 8. The protruding rod 8 is pressed and fitted with the middle of the bottom surface of the vibrating frame 5. Both the top plate of the support frame 4 and the right side of the vibrating frame 5 have through holes. The through holes of the vibrating frame 5 are filled with a strainer 9. The strainer 9 has several round holes. The diameter of the round holes is smaller than the width of the spoon, and each row of round holes in the strainer 9 is staggered. A solid-liquid separation component for collecting food residue is set at the bottom of the through holes of the support frame 4. A tableware washing machine 11 is placed at the bottom right end of the support frame 4.

[0022] like Figure 3 and Figure 4As shown, the solid-liquid separation assembly includes a collection box 10, a frame 12, and a filter screen 13. The collection box 10 is located at the bottom of the strainer plate 9. The frame 12 is snapped into the collection box 10, and the filter screen 13 is connected in the middle of the frame 12. The collection box 10 has a drain outlet 14.

[0023] like Figure 2 As shown, it also includes a splash guard 15. A splash guard 15 is provided between the support frame 4 and the vibration frame 5. The splash guard 15 is located at the bottom of the sluice plate 9 and surrounds the through hole of the top plate of the support frame 4.

[0024] like Figure 4 As shown, it also includes support blocks 16, and support blocks 16 are connected to both the left and right ends of the bottom of the collection box 10.

[0025] The initial end of conveyor 1 is flat. As the plates move along with conveyor 1, they are emptied at the sorting area. Finally, the plates are removed from conveyor 1 and enter separate washing. Food scraps and tableware fall onto sorting rack 3. Due to the feeding port on sorting rack 3, chopsticks, spoons, and food scraps fall from the feeding port, while bowls fall along sorting rack 3 into dishwasher 2. After washing, they are sent to drying and sterilization. Chopsticks, spoons, and food scraps fall onto vibrating rack 5. Motor 7 drives the convex rod 8 to rotate, and the convex rod 8 strikes the vibrating rack 5. This, combined with the return spring 6 connected to the vibrating rack 5, causes the vibrating rack 5 to continuously vibrate up and down on the support frame 4, thus separating food scraps and tableware. When food scraps pass through the strainer 9, the misaligned circular... The holes ensure that residual liquid flows to the collection box 10, and the splash guard 15 restricts the falling path of food residue, preventing it from remaining on the support frame 4. Food residue falls through the round holes of the sluice plate 9, while chopsticks move horizontally along the vibrating frame 5. Finally, the chopsticks and spoons fall into the dishwashing machine 11. After the dishes are washed, they are sent to the drying and sterilization area. Food residue passing through the sluice plate 9 is filtered by the filter screen 13 to achieve solid-liquid separation. The support block 16 suspends the collection box 10, allowing workers to insert tools into the bottom of the collection box 10 to facilitate its movement and pull the frame 12 to separate solid matter. After collection, the solid matter is sent to feed processing plants or biomass power plants for recycling, while the liquid is discharged through the drain outlet 14 to the post-processing area for pollution-free treatment.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
