[0035] In a preferred embodiment, the water outlet pipe 18 is clamped inside the fixed block 19. One end of the water outlet pipe 18 is connected to the outer wall of the water pump 16, and the other end of the water outlet pipe 18 is located inside the lunch box processing component 6. A spray head is fixedly installed on the outer wall of the water outlet pipe 18 away from the water pump 16. The water pump 16 is electrically connected to the central control cabinet 2. The water suction pipe 17 is located inside the water tank 14, and the inner wall of the water tank 14 is filled with water source;

[0036] With the above structure, by the central control cabinet 2 emitting a signal, the water pump 16 can be started, and the water source inside the water tank 14 can be adsorbed through the water suction pipe 17, and sprayed onto the inner wall of the transfer cart 5 by the spray head installed at the bottom of the water outlet pipe 18, so that it can clean the plastic lunch boxes placed on the inner wall of the transfer cart 5.

[0037] In a preferred embodiment, the servo motor 11 is electrically connected to the central control cabinet 2. The cleaning roller 12 is located inside the transfer cart 5 and above the water filtering assembly 8. The self-cleaning filter 10 is electrically connected to the central control cabinet 2.

[0040] In a preferred embodiment, the number of the vertical frames 22, the fixing seats 24, the cylinders 25 and the push plates 28 is three. The three vertical frames 22, the fixing seats 24, the cylinders 25 and the push plates 28 are evenly distributed on the outer wall of the fixing plate 3. The identification camera 23 is electrically connected to the cylinder 25. A negative pressure device is arranged inside the conveyor belt 27, and the negative pressure device is electrically connected to the central control cabinet 2. The conveyor belt 27 is woven from polyester fiber.

[0041] With the above structure, due to the characteristic that the conveyor belt 27 is woven from polyester fiber, it can be known that the conveyor belt 27 has the advantages of excellent air permeability, uniform pore size and smooth air circulation. When the negative pressure device is started, it can adsorb the plastic lunch boxes placed on the top of the conveyor belt 27 by the adsorption force generated by the airflow, effectively preventing the plastic lunch boxes from moving when being transported on the top of the conveyor belt 27 and ensuring the stability of the lunch boxes during the transfer process.

[0042] In a preferred embodiment, the lunch box processing component 6 includes a protective housing 61. A micro motor 62 is fixedly installed at the top of the protective housing 61. A rotating disk 63 is fixedly assembled on the power output shaft of the micro motor 62. Mounting columns 64 are fixedly installed on the outer wall of the rotating disk 63. One end of a rotating handle 65 is rotatably sleeved on the outer wall of the mounting column 64, and the other end of the rotating handle 65 is rotatably sleeved on one end of a driving handle 66. The other end of the driving handle 66 is rotatably connected to a connecting block 67. A window plate 611 is fixedly installed on the outer wall of the connecting block 67. Mounting blocks 610 are fixedly assembled on the outer wall of the window plate 611. One end of a limiting handle 68 is rotatably sleeved on the outer wall of the mounting block 610, and the other end of the limiting handle 68 is rotatably sleeved on a fixing rod 69. A square groove 612 is formed on the outer wall of the protective housing 61. An electric drying rod 613 and a partition plate 614 are respectively fixedly installed at the top of the inner wall of the protective housing 61. A fixing column 615 is rotatably sleeved on the inner wall of the driving handle 66;

[0043] Using the above structure, by sending a signal through the central control cabinet 2, the electric drying rod 613 can be started, so that the electric drying rod 613 can dry the plastic lunch boxes after being cleaned on the inner wall of the transfer cart 5, enabling the plastic lunch boxes to be in a dry state during the transfer process.

[0044] In a preferred embodiment, both the fixing rod 69 and the square groove 612 are fixedly installed on the inner wall of the protective housing 61. Both the mounting block 610 and the connecting block 67 are fixedly installed on the outer wall of the window plate 611. The micro motor 62 is electrically connected to the central control cabinet 2. The window plate 611 is located inside the square groove 612. The number of electric drying rods 613 is several, and several electric drying rods 613 are evenly distributed on the inner wall of the protective housing 61. The electric drying rods 613 are electrically connected to the central control cabinet 2;

[0045] Using the above structure, by sending a signal through the central control cabinet 2, the micro motor 62 can be started and drive the rotating disk 63 to rotate, so that the mounting column 64 can drive the rotating handle 65 to rotate. The window plate 611 can be unfolded outward from the inner wall of the square groove 612 through the driving handle 66, enabling the square groove 612 to be exposed and the inner wall of the protective housing 61 to be in a rapid ventilation state. Due to the setting of the limiting handle 68, it can play a role in limiting the window plate 611, and when the window plate 611 is opened, the hot air inside the protective housing 61 can be quickly dissipated to the outside, effectively preventing the problem that plastic lunch boxes breed bacteria during the transfer process due to humid air.

[0046] In a preferred embodiment, the water filtering component 8 includes a water filtering plate 81. Water filtering holes 82 are formed at both the upper and lower ends of the water filtering component 8. An electric telescopic rod 83 is provided on the outer wall of the water filtering plate 81. A connecting plate 84 is fixedly assembled on the telescopic end of the electric telescopic rod 83. A baffle 85 is fixedly installed on the outer wall of the connecting plate 84;

[0047] In a preferred embodiment, there are several columns of baffles 85 and several columns of water filtration holes 82. The number of columns of the water filtration holes 82 is the same as that of the baffles 85. The width of the baffle 85 is the distance between two longitudinal water filtration holes 82. The distance that the electric telescopic rod 83 drives the connecting plate 84 to stretch and contract once is the width of the baffle 85. The electric telescopic rod 83 is electrically connected to the central control cabinet 2. The water filtration plate 81 is fixedly installed inside the transfer cart 5;

[0048] Using the above structure, when the plastic lunch box is cleaned by this device, the baffle 85 can be in a position corresponding to the water filtration hole 82, so that the water source on the inner wall of the transfer cart 5 will not leak downward. And when the lunch box cleaning is completed, the central control cabinet 2 can emit a signal to start the electric telescopic rod 83, which drives the connecting plate 84 to move a distance equal to the width of the baffle 85 in the direction of the electric telescopic rod 83. At this time, the baffle 85 can be located between two water filtration holes 82, making the water filtration holes 82 completely exposed, and enabling the sewage after the internal cleaning of the transfer cart 5 to flow downward, so that there is no water on its upper side, which is conducive to the drying work of the lunch box.

[0049] Working principle: When using this device to transfer plastic lunch boxes, place the lunch box on the top of conveyor belt 27, and make the lunch box be on the top of conveyor belt 27 near the driving motor 26. A signal can be sent through the central control cabinet 2 to make the driving motor 26 start working, and the negative pressure device placed on the inner wall of conveyor belt 27 is started. The plastic lunch box placed on the top of conveyor belt 27 can be adsorbed by the adsorption force generated by the airflow, which can effectively prevent the plastic lunch box from moving during the transmission on the top of conveyor belt 27, ensuring the stability of the lunch box during the transfer process. During the movement of the lunch box, the recognition camera 23 performs image recognition on the lunch box, enabling it to be used for automatic sorting and positioning before cleaning. When the recognition camera 23 detects the corresponding lunch box, it will emit a signal to start the corresponding cylinder 25, so that the cylinder 25 can push the push plate 28, and the corresponding plastic lunch box will fall into the inner wall of the corresponding transfer vehicle 5. At this time, the central control cabinet 2 can emit a signal to start the water pump 16. The water source in the inner wall of the water tank 14 is adsorbed through the water suction pipe 17, and the nozzle installed at the bottom of the water outlet pipe 18 sprays water onto the inner wall of the transfer vehicle 5. During this process, the servo motor 11 starts working, so that the cleaning roller 12 can start working and clean the plastic lunch box on the inner wall of the transfer vehicle 5. During this process, the activated carbon 13 can use the porous structure on its surface to adsorb dissolved organic matter, odor and trace chemical residues in the water, and can also adsorb the residual organic matter and odor on the lunch box. After the cleaning is completed, the central control cabinet 2 emits a signal to start the electric telescopic rod 83, and drives the connecting plate 84 to move a distance equal to the width of the baffle 85 in the direction of the electric telescopic rod 83. At this time, the baffle 85 is located between the two water filtering holes 82, making the water filtering holes 82 completely exposed, and the sewage after cleaning inside the transfer vehicle 5 can flow downward, so that there is no water on its upper side, and the sewage flows to the bottom of the transfer vehicle 5. At this time, under the control of the central control cabinet 2, the filler 9 and the self-cleaning filter 10 are started. The self-cleaning filter 10 can effectively remove large particle suspended matters in the sewage, and the filler 9 can degrade the oil stains and organic pollutants in the water through the biofilm formed by the attachment of microorganisms on its surface, thereby improving the water quality, enabling the sewage to be recycled, and it can be connected to the vehicle through the connecting hook 15 and the transfer vehicle 5 can be transferred, enabling this device to complete the work of transferring plastic lunch boxes.
