[0002] Fruits and vegetables are the abbreviation of fruits and vegetables, which refer to edible fruits and vegetables. The purpose of preserving fruits and vegetables by coating them is to inhibit respiration, reduce nutrient consumption, inhibit water evaporation, inhibit microbial invasion, prevent corruption and deterioration, and also improve the color of fruits and vegetables, increase brightness and enhance the commercial value of fruits and vegetables.

[0003] After searching, a Chinese patent with publication number CN218681695U discloses a coating device for preserving fruits and vegetables. The structure conveys fruits and vegetables to the inside of the shell through a conveyor belt. Under the action of a water pump, the coating liquid enters the upper and lower pipes through the main pipe, and then is sprayed out through a number of nozzles. The fruits and vegetables can be coated in all directions to ensure that all parts of the fruits and vegetables can be coated, thereby increasing the coating rate of the fruits and vegetables.

[0004] However, when the structure is actually used, firstly, after coating the fruits and vegetables, the excess coating agent will be discharged into the liquid storage tank through the leakage holes on the conveyor belt, but the impurities or dust on the surface of the fruits and vegetables will also be discharged through the leakage holes along with the coating agent, causing the leakage holes on the surface of the conveyor belt to be easily blocked, and it is not convenient to clean the conveyor belt. In addition, the overall width of the receiving bucket of the structure is fixed, which causes fruits and vegetables of different sizes to be easily blocked when they are discharged through the receiving bucket. In view of this, the utility model proposes an automatic fruit and vegetable coating device. Utility Model Content

[0025] As attached Figure 1-6The illustrated automatic film coating device for fruits and vegetables comprises a frame 1, a film coating frame 2 and a liquid storage tank 3. The film coating frame 2 is at the top of the frame 1, and the liquid storage tank 3 is installed at the bottom of the frame 1. A conveyor belt 4 is rotatably arranged inside the frame 1, and a plurality of leakage holes 5 are provided on the surface of the conveyor belt 4. One end of the liquid storage tank 3 is located at the bottom of the frame 1 and is obliquely provided with a material receiving plate 6. A pump 7 is provided on the surface of the liquid storage tank 3, and a delivery pipe 8 is provided at the output end of the pump 7. Liquid separation pipes 9 are provided on both sides of the bottom of the delivery pipe 8, and two drainage pipes 10 are provided on one side of the delivery pipe 8 at the top of the film coating frame 2. Multiple nozzles 11 are provided at one end of the liquid separation pipe 9 and the drainage pipe 10. The input end of the pump 7 extends to the interior of the liquid storage tank 3, and the output end of the pump 7 is connected to the delivery pipe 8. The top ends of the two liquid separation pipes 9 are connected to the bottom of the delivery pipe 8, and one ends of the two drainage pipes 10 are connected to one end of the delivery pipe 8, and the nozzle 11 extends to the interior of the film coating frame 2.

[0026] Specifically, in this structure, first, fruits and vegetables can be transported from the right side to the left side of the conveyor belt 4. During the transportation process, the pump 7 transports the coating agent in the liquid storage tank 3 through the conveying pipe 8, and uses two liquid separation pipes 9 to transport the coating agent to both sides of the coating frame 2 through the nozzle 11. At the same time, two liquid discharge pipes 10 are used to transport the coating agent to the top of the coating frame 2 through the corresponding nozzle 11, so that the fruits and vegetables on the conveyor belt 4 can be evenly coated. The coated coating agent can enter the liquid storage tank 3 through the leakage hole 5 on the conveyor belt 4 for recovery, reducing the waste of the coating agent, and the coated fruits and vegetables are discharged to the next device through the receiving plate 6 for processing;

[0027] It is worth noting that the frame 1 and the conveyor belt 4 in the present invention are existing structures. The conveyor belt 4 is installed inside the frame 1. The motor drives the roller to rotate so that the conveyor belt 4 runs inside the frame 1 to transport fruits and vegetables. The specific principle of this structure is the existing technology and will not be described in detail.

[0028] In a specific embodiment, as shown in the attached Figure 2 , 3As shown in Figure 4, a cleaning structure is provided inside the frame 1 on one side of the conveyor belt 4, and the cleaning structure includes a screw rod 12. Both inner walls of the frame 1 are provided with mounting grooves 13. The screw rod 12 is installed in one of the mounting grooves 13, and a slide rod 14 is provided in the other mounting groove 13. An adjusting block 15 is provided at the top of the screw rod 12. Threaded blocks 16 and sliders 17 are provided on the outside of the screw rod 12 and the slide rod 14. A Z-shaped plate 18 is provided between the threaded block 16 and the slider 17. A cleaning brush 19 is provided on the surface of the Z-shaped plate 18. The threaded block 16 and the slider 17 are respectively threadedly connected and slidably connected to the outside of the screw rod 12 and the slide rod 14, and the threaded block 16 and the slider 17 are respectively fixedly installed at both ends of the Z-shaped plate 18, and one end of the Z-shaped plate 18 extends to the bottom of the conveyor belt 4.

[0029] Specifically, in this structure, during the process of coating fruits and vegetables on the conveyor belt 4, since there are more or less impurities on the surface of fruits and vegetables, when the coating agent is sprayed on the surface of fruits and vegetables and the excess coating agent is discharged through the leakage hole 5 on the surface of the conveyor belt 4, it is easy to cause the leakage hole 5 to be blocked;

[0030] Then, the operator can rotate the adjusting block 15 to rotate the screw rod 12 in one of the mounting grooves 13, so that the threaded block 16 drives the Z-shaped plate 18 to approach the lower surface of the conveyor belt 4, so that the slider 17 at one end of the Z-shaped plate 18 slides and guides outside the slide rod 14, and the Z-shaped plate 18 drives the cleaning brush 19 to fit the lower surface of the conveyor belt 4. Then, during the operation of the conveyor belt 4, the cleaning brush 19 can fit the bottom of the conveyor belt 4 for cleaning, so as to avoid clogging of the leakage hole 5 on the surface of the conveyor belt 4, and at the same time, prevent the impurities on the conveyor belt 4 from affecting the next use;

[0031] After cleaning is completed, the Z-shaped plate 18 can be moved away from the lower surface of the conveyor belt 4 so that the cleaning brush 19 on the surface of the Z-shaped plate 18 does not contact the bottom of the conveyor belt 4 .

[0032] In a specific embodiment, as shown in the attached Figure 1 , 5 As shown, the receiving plate 6 is hollow, and two L-shaped plates 20 are slidably arranged inside the receiving plate 6. A support plate 21 is arranged at the central part of the bottom of the receiving plate 6. Electric push rods 22 are fixedly installed on both side walls of the support plate 21. The output ends of the two electric push rods 22 are respectively connected to the corresponding L-shaped plates 20.

[0033] Specifically, in this structure, since fruits and vegetables are of different sizes, in order to avoid the phenomenon of clogging when fruits and vegetables of different sizes are discharged through the receiving plate 6, the two electric push rods 22 at the bottom support plate 21 of the receiving plate 6 push the L-shaped plate 20 to both sides respectively, so that one end of the L-shaped plate 20 slides inside the hollow receiving plate 6, thereby expanding the overall width of the receiving plate 6, ensuring the smoothness of the discharge of fruits and vegetables of different sizes and avoiding clogging.

[0034] In a specific embodiment, as shown in the attached Figure 6 As shown, a filter screen 23 is slidably provided inside the liquid storage tank 3, a slide groove is provided on the outer wall at the rear side of the liquid storage tank 3, the filter screen 23 is slidably installed inside the liquid storage tank 3 through the slide groove, a mounting plate 24 is provided at one end of the filter screen 23, the mounting plate 24 is installed on the outer wall at the rear side of the liquid storage tank 3 by screws, and a handle is provided on the surface of the mounting plate 24.

[0035] Specifically, in this structure, after the excess coating agent on the surface of fruits and vegetables enters the interior of the liquid storage tank 3, it can be filtered through the filter screen 23 to prevent residual impurities in the coating agent from affecting use. The operator removes the screws on the mounting plate 24 and pulls the mounting plate 24 outward through the handle, so that the mounting plate 24 drives the filter screen 23 to be pulled out from the interior of the liquid storage tank 3 through the slide groove, and the filter screen 23 can be cleaned and replaced.

[0036] In a specific embodiment, as shown in the attached Figure 1 As shown, protective curtains 25 are detachably mounted on both ends of the coating frame 2 , and both protective curtains 25 are located above the conveyor belt 4 .

[0037] Specifically, in this structure, the protective curtain 25 can not only prevent the coating liquid from escaping and affecting the normal operation of various components of the device, but also ensure the recovery rate of the coating liquid.

[0038] Working principle of this utility model:

[0039] When the above structure is used, first, fruits and vegetables are transported from the right side to the left side through the conveyor belt 4. During the transportation, the pump 7 transports the coating agent in the liquid storage tank 3 through the conveying pipe 8, and the coating agent is transported to the two sides of the coating frame 2 through the nozzle 11 by two liquid distribution pipes 9. At the same time, the coating agent is transported to the top of the coating frame 2 through the corresponding nozzle 11 by two liquid discharge pipes 10, so that the fruits and vegetables on the conveyor belt 4 can be evenly coated.

[0040] After coating, the coating agent can enter the liquid storage tank 3 through the leakage hole 5 on the conveyor belt 4 for recycling, reducing the waste of the coating agent. After the excess coating agent on the surface of fruits and vegetables enters the liquid storage tank 3, it can be filtered through the filter screen 23 to avoid the residual impurities in the coating agent affecting the use. The operator removes the screws on the mounting plate 24 and pulls the mounting plate 24 outward through the handle, so that the mounting plate 24 drives the filter screen 23 to be drawn out from the liquid storage tank 3 through the chute, and the filter screen 23 can be cleaned and replaced.

[0041] The coated fruits and vegetables are discharged to the next device through the receiving plate 6 for processing. The two electric push rods 22 at the bottom support plate 21 of the receiving plate 6 push the L-shaped plate 20 to the two sides respectively, so that one end of the L-shaped plate 20 slides inside the hollow receiving plate 6, thereby expanding the overall width of the receiving plate 6, ensuring the smoothness of the discharge of fruits and vegetables of different sizes and avoiding blockage.

[0042] The operator can rotate the adjustment block 15 to rotate the screw rod 12 inside one of the mounting grooves 13, so that the threaded block 16 drives the Z-shaped plate 18 to approach the lower surface of the conveyor belt 4, so that the slider 17 at one end of the Z-shaped plate 18 slides and guides on the outside of the slide rod 14, and the Z-shaped plate 18 drives the cleaning brush 19 to fit the lower surface of the conveyor belt 4. Then, during the operation of the conveyor belt 4, the cleaning brush 19 can fit the bottom of the conveyor belt 4 for cleaning, so as to avoid clogging of the leakage holes 5 on the surface of the conveyor belt 4. At the same time, it can avoid impurities on the conveyor belt 4 affecting the next use. After cleaning, the Z-shaped plate 18 can be moved away from the lower surface of the conveyor belt 4, so that the cleaning brush 19 on the surface of the Z-shaped plate 18 does not contact the bottom of the conveyor belt 4.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
