[0002] After the food is packaged in a box and sealed, in order to ensure that the surface of the box is clean and pollution-free, the sealed box needs to be sprayed and cleaned.

By installing the detection probe near the position after the packaging box is turned over, the detection probe can quickly detect the leaked food, preventing the leaked food from completely contaminating the water on the right side of the cleaning pool and contaminating the packaging box that has been turned over in the front. The front and back sides of the packaging box are squeezed by the squeezing rod to expand the gap between the sealing part and the packaging box, which is conducive to monitoring the leaked food by the detection probe after the packaging box is turned over, thereby minimizing the contamination range of the water on the right side of the cleaning tank, and further avoiding contamination of the packaging box that has been turned over in front.

DETAILED DESCRIPTION

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0019] Example 1 like Figure 1-Figure 6 As shown, a surface cleaning device for a packaging box includes a cleaning pool 1, a conveyor belt 2 and a spray pipe 3; the cleaning pool 1 is equipped with a conveyor belt 2; a water pipe 1001 is provided on the cleaning pool 1, and the water pipe 1001 is connected to an external pump; five spray pipes 3 are provided on the cleaning pool 1, and all the spray pipes 3 are connected to the water pipe 1001; It also includes a rotating shaft 4, an L-shaped flip plate 5, a limiting rod 201 and a rotating component; a partition 1002 is arranged in the cleaning pool 1, and the partition 1002 is used to separate the cleaning pool 1 into two front and rear cleaning slots; a connecting block 1003 is arranged on the left side of the cleaning pool 1, and the connecting block 1003 is connected to the external pump 2; the cleaning pool 1 is connected to two front-to-back symmetrical rotating components; each rotating component is connected to a rotating shaft 4, and the rotating shaft 4 is rotatably connected to the inner wall of the cleaning pool 1 and the partition 1002; an L-shaped flip plate 5 is fixedly connected to each rotating shaft 4; the rotating component is used to drive the L-shaped flip plate 5 to rotate through the rotating shaft 4; an infrared sensing device is arranged on the cleaning pool 1, and the infrared sensing device is located between the horizontal part and the vertical part of the L-shaped flip plate 5; each L-shaped flip plate 5 is arranged on three first flow slots 5001; two front-to-back symmetrical limiting rods 201 are fixedly connected to the partition 1002 of the cleaning pool 1.

[0020] The rotating assembly includes a fixed block 101, a driving motor 102 and an output shaft 103; the fixed block 101 is fixedly connected to the cleaning tank 1; the driving motor 102 is fixedly connected to the fixed block 101; the output end of the driving motor 102 is fixedly connected to the output shaft 103, and the output shaft 103 is connected to the corresponding rotating shaft 4.

[0021] The spray head of each spray pipe 3 is inclined toward the packaging box.

[0022] The working steps of this embodiment are: Preparation work: Inject water into the cleaning pool 1 in advance, set a collection frame or conveying device on the right side of the cleaning pool 1, so that the cleaned packaging boxes can be collected or conveyed to the subsequent process, and with the upper surface of the conveyor belt 2 as a reference, the distance between the water surface in the cleaning pool 1 and the upper surface of the conveyor belt 2 is less than the height of the packaging boxes, and then start the external pump 1 to allow water to be injected into the spray pipe 3 through the water pipe 1001, and the spray pipe 3 starts the spraying operation. At the same time, start the external pump 2 to pump out the water in the cleaning pool 1 through the connecting block 1003. The water flow direction in the cleaning pool 1 is to flow to the left to ensure that the water surface in the cleaning pool 1 will not immerse the packaging boxes. At the same time, start the conveyor belt 2 to run, and the conveyor belt 2 runs clockwise based on the view from front to back.

[0023] Cleaning work: After the preparation work is completed, the packaging box is transported to the inclined surface of the connecting block 1003 at a rate of 3 seconds through the external loading device. Under the influence of gravity, the packaging box automatically slides onto the conveyor belt 2, and the conveyor belt 2 drives the packaging box to the right and gradually passes through the spray pipe 3, and the spray pipe 3 cleans the surface of the packaging box. During the cleaning process, since the water surface in the cleaning pool 1 is below the packaging box, the water flow sprayed by the spray pipe 3 will not flush the packaging box into the water during the cleaning process, so as to avoid the water in the cleaning pool 1 to buffer and disperse the impact force of the water flow sprayed by the spray pipe 3, resulting in the difficulty of the water flow to concentrate on removing the dirt on the surface of the packaging box, which affects the cleaning effect of the packaging box; it should be noted that the connecting block 1003 is provided with a supporting net at the drainage position to prevent the packaging box from being stuck on the inclined surface of the connecting block 1003, and the cleaning pool 1 is divided into two front and rear cleaning slots by the partition 1002, and the cleaning slot is only for one packaging box to pass through, so as to avoid the packaging boxes from stacking in the cleaning pool 1 and affecting the cleaning effect of the packaging boxes.

[0024] During the process of cleaning the packaging box, although there is a continuous flow of water in the cleaning tank 1, the bottom surface of the packaging box in contact with the conveyor belt 2 is poorly cleaned. In order to improve the cleaning effect of the packaging box, when the infrared sensing device on the cleaning tank 1 is triggered, it means that the conveyor belt 2 transports the packaging box to the L-shaped flip plate 5. At this time, based on the view from front to back, the drive motor 102 is controlled to drive the output shaft 103, the rotating shaft 4 and the L-shaped flip plate 5 to rotate clockwise, so that the packaging box on the L-shaped flip plate 5 is turned over. After turning over, the upper surface of the packaging box contacts the conveyor belt 2. The conveyor belt 2 continues to transport the inverted packaging box to the right, and the bottom surface of the packaging box is cleaned through the subsequent spray pipe 3 of the cleaning pool 1 to ensure the cleaning effect of the packaging box; it should be noted that after the L-shaped flip plate 5 rotates clockwise to turn the packaging box over, the drive motor 102 drives the output shaft 103, the rotating shaft 4 and the L-shaped flip plate 5 to rotate counterclockwise and reset to turn over the subsequent packaging boxes; it should be noted that the conveyor belt 2 is squeezed by the limiting rod 201, so that the conveyor belt 2 is concave downward, and the L-shaped flip plate 5 is avoided to rotate clockwise, so that the packaging box can be turned over smoothly.

[0025] Since the nozzle of the spray pipe 3 in the prior art is set downward, that is, the nozzle of the spray pipe 3 is directly opposite to the packaging box, when cleaning a square or round packaging box, the side of the packaging box is parallel to the water flow sprayed by the spray pipe 3, the impact force is limited, and the cleaning effect is poor. When cleaning a trapezoidal packaging box, if the side of the trapezoidal packaging box is tilted inward, the water flow sprayed by the spray pipe 3 cannot contact the side of the packaging box. Although there is a continuously flowing water flow in the cleaning pool 1, the water flow impact force is limited, and the cleaning effect on the side of the packaging box is limited. For this reason, the present invention ensures effective cleaning of different packaging boxes by changing the direction of the nozzle of the spray pipe 3. The specific method is as follows: first, with the L-shaped flip plate 5 as the boundary, the nozzles of the two spray pipes 3 located on the left side of the L-shaped flip plate 5 are relatively tilted, and with the partition 1002 as the boundary, the two nozzles of the spray pipe 3 located in front of the partition 1002 are relatively tilted, that is, in the process of the packaging box passing through the spray pipe 3, the spray pipe 3 can fully clean the packaging box to ensure the cleaning effect of the packaging box.

[0027] All detection probes 1005 installed on the cleaning tank 1 and the partition 1002 are close to the rotation path of the L-shaped flip plate 5.

[0028] It also includes an elastic member 401, a guide plate 402, an extrusion rod 403 and an arc block 404; four elastic members 401 are fixedly connected to the transverse part of each L-shaped flip plate 5, and the elastic member 401 is a spring telescopic rod; two front-to-back symmetrical telescopic parts 5003 are arranged on the transverse part of each L-shaped flip plate 5, and the telescopic end of each elastic member 401 is located in the adjacent telescopic part 5003, and the telescopic part 5003 is in close contact with the inner wall of the cleaning pool 1 and the partition 1002; the telescopic ends of all elastic members 401 located in the same telescopic part 5003 are commonly fixedly connected to the guide plate 402; a curved surface 40201 is arranged on the side of each guide plate 402 away from the L-shaped flip plate 5; an extrusion rod 403 is arranged on the side of each guide plate 402 close to the L-shaped flip plate 5; two arc blocks 404 are fixedly connected to the cleaning pool 1, and two arc blocks 404 are also fixedly connected to the partition 1002.

[0029] A limiting portion 40401 is provided on each bending block 404 .

[0030] Each curved surface 40201 is configured to be larger at the top and smaller at the bottom, so as to facilitate the movement of the guide plate 402 after being restricted by the curved block 404 .

[0031] The two squeezing rods 403 on the same L-shaped flip plate 5 are combined in an eight-shaped shape to guide and limit the packaging box conveyed to the L-shaped flip plate 5 to prevent the packaging box from being tilted, thereby ensuring the squeezing effect of the squeezing rods 403 on the packaging box.

[0032] It also includes a telescopic block 405 and a limiting rod 406; a telescopic block 405 is provided at one end of each guide plate 402 close to the vertical part of the L-shaped flip plate 5; a plurality of limiting holes 40501 are provided on the telescopic structure of each telescopic block 405; one end of the extrusion rod 403 is rotatably connected to the adjacent guide plate 402, and the other end is rotatably connected to the telescopic structure on the adjacent telescopic block 405; a limiting rod 406 is inserted into each telescopic block 405, and the limiting rod 406 is inserted into the limiting hole 40501.

[0033] An alarm device is provided on the cleaning pool 1, and the alarm device is connected to the detection probe 1005 via Bluetooth.

[0034] The working process of this embodiment is as follows: After the packaging boxes are sealed by the sealing machine, a small number of packaging boxes are not tightly sealed, that is, there is a small gap between the sealing film and the packaging box. When the sealed packaging boxes are cleaned, the packaging boxes will be immersed in water. If the packaging boxes are not tightly sealed at this time, the food packaged in the packaging boxes will leak, causing the water in the entire cleaning tank 1 and other packaging boxes to be contaminated. The contaminated packaging boxes and the sewage in the cleaning tank 1 need to be manually processed, which increases additional manpower and costs. For this reason, the present invention prevents the food in the packaging boxes from leaking into the water by making the water level in the cleaning tank 1 lower than the surface of the packaging box.

[0035] However, in order to ensure the overall cleaning effect of the packaging box, the packaging box needs to be turned over for cleaning. However, after the packaging box is turned over, the food in the packaging box will leak through the gap. For this reason, the turbidity of the water is detected in real time by the detection probe 1005 in the cleaning tank 1 (the detection principle is: when the light emitted by the turbidity detector propagates in the water, it will be scattered or absorbed when it encounters suspended particles in the water, so the turbidity of the water is measured according to the degree of scattering or absorption of light). After the L-shaped flip plate 5 rotates to force the packaging box to turn over, if there is a problem of food leakage, the detection probe 1005 will be triggered at this time, and the detection probe 1005 will send a signal to control the conveyor belt 2 to stop running, and control the output end of the driving member 301 to shrink, and the driving member 301 drives the adjacent sealing member 301 through the mounting block 30101 at its output end. The blocking block 1004, the connecting portion 10301 of the output shaft 103 and the connecting rod 302 move away from the cleaning pool 1, so that the blocking block 1004 no longer blocks the drain port of the cleaning pool 1, and the connecting rod 302 forces the second flow groove 30301 on the blocking plate 303 to no longer be aligned with the first flow groove 5001 of the adjacent L-shaped flip plate 5, so that the water on the left and right sides of the cleaning pool 1 are separated by the L-shaped flip plate 5, thereby preventing the polluted water on the right side of the cleaning pool 1 from affecting the water on the left side of the cleaning pool 1, i.e., preventing the water in the cleaning pool 1 from being fully polluted, thereby reducing the cost of water use. At the same time, the polluted water on the right side of the cleaning pool 1 is discharged into the drainage box 304 through the drain port of the cleaning pool 1, thereby preventing sewage from polluting the subsequent packaging boxes that have not been turned over and the packaging boxes that have been turned over previously.

[0036] It should be noted that by arranging an alarm device on the cleaning pool 1, and connecting the alarm device to the detection probe 1005 through wireless technology, when the detection probe 1005 is triggered, the alarm device is activated to prompt a person to take out the leaking package box, and the detection probe 1005 is installed near the position after the package box is turned over, so that the detection probe 1005 can quickly detect the leaked food, so as to prevent the leaked food from completely contaminating the water on the right side of the cleaning pool 1 and contaminating the package box that has been turned over in front. Note that when the contaminated water passes through the drain port of the cleaning pool 1 When the leaking package box is discharged and manually taken out, the spray pipe 3 on the right side of the cleaning pool 1 is manually controlled to continue the spraying operation, and the nozzle of the spray pipe 3 on the right side of the cleaning pool 1 near the L-shaped flip plate 5 is directed toward the corresponding position of the conveyor belt 2 and the detection probe 1005, so as to process the leaked material remaining on the conveyor belt 2. Since the detection probe 1005 is installed near the position after the package box is turned over, after the detection probe 1005 is triggered to stop the conveyor belt 2, the contact position between the conveyor belt 2 and the leaking package box is within the cleaning range of the nozzle of the spray pipe 3 near the L-shaped flip plate 5.

[0037] It should be noted that the contact parts between the connecting block 1003 and the conveyor belt 2 and the contact parts between the conveyor belt 2 and the cleaning pool 1 are both provided with sealing structures, and the water is only located between the cleaning pool 1 and the conveyor belt 2 to avoid comprehensive contamination of the water in the cleaning pool 1.

[0038] It should be noted that after the contaminated water is discharged through the drain port of the cleaning pool 1, the leaking packaging box is manually taken out, and the conveyor belt 2 is manually checked for cleanliness, the adjacent blocking blocks 1004 and the blocking plate 303 are reset by the manually controlled driving member 301, and then the conveyor belt 2 is started to continue cleaning the packaging box.

[0039] When the L-shaped flip plate 5 drives the packaging box to turn over, the L-shaped flip plate 5 drives the curved surface 40201 of the guide plate 402 to gradually approach the curved block 404. Under the restriction of the curved block 404, the guide plate 402 drives the telescopic end of the elastic member 401 to approach the packaging box, so that the squeezing rod 403 squeezes the front and rear sides of the packaging box, so that the sealing part of the packaging box expands outward. For a packaging box that is not tightly sealed, the gap between the sealing part and the packaging box will gradually expand, which is conducive to the detection probe 1 after the packaging box is turned over. 005 monitors the leaked food to minimize the contaminated range of the water on the right side of the cleaning tank 1, and further avoids contamination of the packaging box that has been turned over in the front; it should be noted that when the L-shaped flip plate 5 drives the packaging box to turn over, the part of the packaging box supported by the L-shaped flip plate 5 will separate the water in the cleaning tank 1, and at the same time, the telescopic part 5003 of the L-shaped flip plate 5 is tightly fitted with the adjacent curved block 404, ensuring the water separation effect of the L-shaped flip plate 5 during the flipping process, and avoiding the leaked food from contaminating the water on the left side of the cleaning tank 1.

[0040] When the L-shaped flip plate 5 drives the packaging box to turn over, after the telescopic part 5003 of the L-shaped flip plate 5 passes through the curved block 404, the telescopic part 5003 will contact the limiting part 40401. When the L-shaped flip plate 5 needs to be reset, the limiting part 40401 guides the L-shaped flip plate 5 to avoid the curved block 404 blocking the L-shaped flip plate 5 when the L-shaped flip plate 5 drives the packaging box to turn over and passes through the curved block 404. When the L-shaped flip plate 5 is reset, the curved block 404 will prevent the L-shaped flip plate 5 from being blocked and affecting the reset of the L-shaped flip plate 5.

[0041] Furthermore, taking into account the different sizes of packaging boxes, in order to improve the ease of use and applicability of the device, a person only needs to pull up the limiting rod 406 on the telescopic block 405 according to the size of the packaging box, and push the telescopic structure on the telescopic block 405 to extend or contract the telescopic structure on the telescopic block 405, adjust the length of the telescopic block 405, and then press the limiting rod 406 down again to reinsert the limiting rod 406 into the limiting hole 40501 of the telescopic structure. In this way, packaging boxes of different sizes can be squeezed.

[0042] 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 principle of the present invention should be included in the protection scope of the present invention.
