[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] Before express delivery, a logistics disinfection device is required to spray disinfectant on the outer surface of the logistics box. An existing logistics disinfection device has a conveyor belt and a disinfection mechanism. The conveyor belt is used to transport express delivery. The conveyor belt is provided with multiple hollow holes to form a mesh structure. The disinfection mechanism is located below the conveyor belt and sprays disinfectant through upward nozzles. The disinfectant passes through the hollow holes and is sprayed on the lower surface of the express delivery. However, the contact point between the lower surface of the logistics box and the conveyor belt is blocked and cannot be sprayed with disinfectant, resulting in insufficient disinfection of the lower surface of the logistics box.

[0041] Reference Figures 1 to 4, a logistics disinfection device according to an embodiment of the present invention, includes a first base 100, a conveyor belt 200, a disinfection mechanism 300, and a displacement mechanism 400. The conveyor belt 200 is mounted on the first base 100 and is provided with a plurality of hollow holes. The disinfection mechanism 300 is provided with a first nozzle 310 facing upward. The disinfection mechanism 300 is mounted on the first base 100 and is located below the conveyor belt 200. The displacement mechanism 400 is mounted on the first base 100 and is used to shift objects on the conveyor belt 200 relative to the conveyor belt 200 along the conveying plane of the conveyor belt 200.

[0042] When the logistics disinfection device is in use, the logistics box is placed on the conveyor belt 200 and is driven by the conveyor belt 200 to move. The disinfection mechanism 300 can spray disinfectant on the lower surface of the logistics box that is not blocked by the conveyor belt 200 through the hollow holes of the conveyor belt 200 through the first nozzle 310 set upward. During this period, the offset mechanism 400 can cause the logistics box to shift relative to the conveyor belt 200 in the conveying plane direction, replacing the portion of the logistics box's lower surface that is blocked by the conveyor belt 200, so that the portion of the logistics box's lower surface that was originally in contact with the conveyor belt 200 is no longer blocked. The first nozzle 310 sprays disinfectant, which passes through the hollow holes and disinfects this portion. The above structure can more thoroughly disinfect the lower surface of the logistics box. In the embodiment, the direction of the conveying object of the conveyor belt 200 refers to the front-to-back direction; the conveying plane direction of the conveyor belt 200 refers to the direction in which the object can move relative to the conveyor belt 200 when placed on the conveyor belt 200, that is, the direction contained in the upper plane of the conveyor belt 200. In this embodiment, the conveying plane direction of the conveyor belt 200 is the horizontal direction.

[0043] Specifically, the number of the hollow holes is three or more, so that the conveyor belt 200 forms a mesh-like structure. Specifically, the conveyor belt 200 can be a conveyor mesh belt, or other conveyor belts 200 with multiple hollow holes.

[0044] Specifically, in this embodiment, the object refers to a logistics box. In other embodiments, the object may also be an object other than a logistics box, such as a logistics bag or the goods themselves.

[0045] In this embodiment, the offset mechanism 400 is a guide structure disposed above the conveyor belt 200. The guide structure is used to guide objects on the conveyor belt 200 to move perpendicularly to the direction in which the conveyor belt 200 is conveying the objects. The guide structure guides the objects to move relative to the conveyor belt 200 perpendicularly to the direction in which the conveyor belt 200 is conveying the objects. This displacement is achieved by utilizing the power of the conveyor belt 200 itself and the guide structure. This structure is simple and does not require an additional power source.

[0046] In an embodiment, the guide structure includes a plurality of guide members 410 arranged in a straight line, the guide members 410 extending vertically, and the arrangement direction of the guide members 410 being tilted relative to the direction of the conveying object of the conveyor belt 200. The guide members 410 are arranged vertically, and the arrangement direction of the plurality of guide members 410 is tilted relative to the direction of the conveying object of the conveyor belt 200, so that the objects on the conveyor belt 200 can be abutted by the guide members 410 and guided to move sideways relative to the conveyor belt 200, thereby continuously changing the portion of the lower surface of the logistics box that is blocked, facilitating the full disinfection of the lower surface. Specifically, the number of guide members 410 provided can be three, four, five or more, arranged in rows, to facilitate the position of the mobile logistics box relative to the conveyor belt 200.

[0047] In an embodiment, the guide member 410 is configured as a guide roller, which is pivotally connected to the first base 100. The guide roller is pivotally connected to the first base 100. When the logistics box touches the inclined rows of guide rollers, the guide roller can rotate, reducing the friction of the logistics box relative to the guide member 410, thereby facilitating the displacement of the logistics box relative to the conveyor belt 200.

[0048] In the embodiment, the direction in which the object is conveyed along the vertical conveyor belt 200 refers to the left-right direction.

[0049] It is conceivable that the guide member 410 can also be a vertically arranged light rod. It is conceivable that the guide mechanism can also be other structures, for example, the guide structure is a plate body, which is arranged vertically and tilted relative to the conveyor belt 200, so that when the logistics box collides with the plate body, it can also move sideways relative to the conveyor belt 200.

[0050] It is conceivable that the offset mechanism 400 can also be other structures. For example, the offset mechanism 400 includes a stopper pivotally connected to the first base 100, a motor and a photoelectric sensor for driving the stopper. The photoelectric sensor is used to detect whether a logistics box passes on the upper side of the conveyor belt 200. The photoelectric sensor controls the rotation of the motor to drive the stopper to rotate above the conveyor belt 200 or move away. The stopper can cause the logistics box to be displaced in the front-to-back direction relative to the conveyor belt 200 to achieve similar functions; or the offset mechanism 400 can also include a cylinder and a photoelectric sensor. The photoelectric sensor is used to detect whether a logistics box passes on the upper side of the conveyor belt 200. The cylinder can push the logistics box to be displaced on the conveying plane relative to the conveyor belt 200.

[0051] Optionally, in some embodiments, the first nozzles 310 are arranged in at least two rows, with each row of first nozzles 310 spaced apart along the direction of the conveyor belt 200 conveying the object. In an embodiment, the first nozzles 310 are arranged in four rows, each row including three first nozzles 310. The first nozzles 310 in each row are spaced apart in the left-right direction, forming a large area for spraying the disinfectant, with a simple structure and easy implementation. It is conceivable that the first nozzles 310 can also be arranged in two, three, or more rows, which can be determined by those skilled in the art based on actual needs; and the number of first nozzles 310 in each row can also be two, three, or more, which can be determined by those skilled in the art based on actual needs.

[0052] Optionally, in some embodiments, at least two first nozzles 310 are arranged along the conveying direction of the conveyor belt 200. Arranging a row of first nozzles 310 along the conveying direction of the conveyor belt 200 provides a better disinfection effect. Specifically, the number of first nozzles 310 can be two, three, or more, and those skilled in the art can determine this based on actual needs.

[0053] There is also a logistics disinfection device that can disinfect the six sides of the outer surface of the logistics box. The disinfection process requires continuous rolling of the logistics box to disinfect the outer surface of the logistics box. The rolling process can easily damage the goods in the logistics box, so further improvements are needed.

[0054] In the embodiment, the direction of conveying objects of the conveyor belt 200 is the front-to-back direction, the first machine base 100 is provided with a disinfection chamber 110, the front side wall of the disinfection chamber 110 is provided with a delivery port 111, the rear side wall of the disinfection chamber 110 is provided with an entrance port 112, the conveyor belt 200 is passed through the disinfection chamber 110, the disinfection mechanism 300 is provided with a plurality of second nozzles 320, and the left side wall, right side wall and upper side wall of the disinfection chamber 110 are provided with second nozzles 320. A disinfection chamber 110 is provided on the first machine base 100, and the conveyor belt 200 is located in the disinfection chamber 110. The atomized disinfectant can stay in the air of the disinfection chamber 110, which is convenient for disinfecting other surfaces of the logistics box and improving the utilization efficiency of the disinfectant. A second nozzle 320 is provided on the other side wall of the disinfection chamber 110. The disinfection mechanism 300 can spray disinfectant on surfaces other than the lower surface of the logistics box through the second nozzle 320, thereby realizing a six-sided disinfection function and disinfecting all surfaces of the logistics box at one time. The structure is simple and easy to implement.

[0055] Specifically, the guide roller is pivotally connected to the upper side wall of the disinfection chamber 110 .

[0056] Specifically, two second nozzles 320 are provided on the upper side wall of the disinfection chamber 110. The two second nozzles 320 are tilted downward, and the two second nozzles 320 located on the upper side wall are arranged front and back. One of the second nozzles 320 sprays disinfectant on the upper and rear surfaces of the logistics box, while the other second nozzle 320 disinfects the upper and front surfaces of the logistics box. The second nozzle 320 provided on the left side wall of the disinfection chamber 110 can disinfect the left surface of the logistics box, and the second nozzle 320 provided on the right side wall can disinfect the right surface of the logistics box. Together with the first nozzle 310 of the disinfection mechanism 300, a six-sided disinfection function is achieved.

[0057] Specifically, the first nozzle 310 and the second nozzle 320 are both atomizing nozzles. Specifically, the disinfection mechanism 300 includes a liquid storage tank 330, a liquid pump 340, and an air compressor 350. The liquid pump 340 pumps the disinfectant in the liquid storage tank 330 into the pipeline. The air output by the air compressor 350 mixes with the disinfectant in the pipeline, thereby atomizing and spraying the disinfectant. It is conceivable that the disinfection mechanism 300 may include a liquid storage tank 330 and a liquid pump 340. The liquid pump 340 directly pumps the disinfectant in the liquid storage tank 330 into the first nozzle 310 and the second nozzle 320 to form a spray.

[0058] In the embodiment, the first base 100 is provided with a front windshield 120 for shielding the delivery port 111 and a rear windshield 130 for shielding the inlet port 112. The provision of the front windshield 120 and the rear windshield 130 prevents the disinfectant in the disinfection chamber 110 from being blown out of the disinfection chamber 110 by external wind, thereby reducing pollution to the environment and improving the utilization rate of the disinfectant.

[0059] Specifically, the front windshield curtain 120 and the rear windshield curtain 130 may be made of polyvinyl chloride, or may be made of cloth or other materials. Those skilled in the art may choose the material according to actual needs.

[0060] In an embodiment, the logistics disinfection device further includes a second base 500 and an entry conveyor belt 600. The entry conveyor belt 600 is disposed on the second base 500. The direction of the conveying objects of the entry conveyor belt 600 is the front-to-back direction. The front end of the entry conveyor belt 600 is docked with the rear end of the conveyor belt 200. The logistics disinfection device further includes a third base 700 and an exit conveyor belt 800. The exit conveyor belt 800 is disposed on the third base 700. The direction of the conveying objects of the exit conveyor belt 800 is the front-to-back direction. The rear end of the exit conveyor belt 800 is docked with the front end of the conveyor belt 200. The second base 500 and the entry conveyor belt 600 are provided to facilitate connection to other areas and to automatically deliver logistics boxes to the rear end of the conveyor belt 200. The third base 700 and the exit conveyor belt 800 are provided to facilitate automatically delivering logistics boxes from the front end of the conveyor belt 200 to other areas. Specifically, the entry conveyor belt 600 is docked with the conveyor belt 200, which means that objects on the entry conveyor belt 600 can be moved to the conveyor belt 200; the delivery conveyor belt 800 is docked with the conveyor belt 200, which means that objects on the conveyor belt 200 can be moved to the delivery conveyor belt 800.

[0061] Specifically, the conveyor belt 600 and the conveyor belt 800 are belt conveyors. It is conceivable that the conveyor belt 600 and the conveyor belt 800 can also be other types of conveyor belts, such as mesh transmission belts, or plate conveyor belts.

[0062] In the embodiment, the second machine base 500 is provided with an entry channel 510 along the front-to-back direction, the entry conveyor belt 600 is passed through the entry channel 510, the second machine base 500 is provided with an air curtain blower 900, the air curtain blower 900 is located at the rear side of the entry channel 510, and the front end of the entry channel 510 is connected to the entry port 112; the third machine base 700 is provided with an outlet channel 710 along the front-to-back direction, the outlet conveyor belt 800 is passed through the outlet channel 710, the third machine base 700 is provided with an air curtain blower 900, the air curtain blower 900 is located at the front side of the outlet channel 710, and the rear end of the outlet channel 710 is connected to the outlet 111.

[0063] An entry channel 510 is provided in the second base 500 along the front-to-back direction, and an air curtain blower 900 is provided at the rear side of the entry channel 510 so that the rear side of the entry channel 510 is shielded by the air curtain. The front end of the entry channel 510 is opposite to the rear wind curtain 130, so that the entry channel 510 can form a relatively airtight space, thereby reducing the risk of the atomized disinfectant in the disinfection chamber 110 entering the external environment through the entry channel 510.

[0064] Similarly, a delivery channel 710 is opened in the front-to-back direction of the third base 700, and an air curtain blower 900 is set on the front side of the delivery channel 710, so that the front end of the delivery channel 710 is blocked by the wind curtain, and the rear end of the delivery channel 710 is opposite to the front windshield 120, so that the delivery channel 710 can form a relatively closed space for airflow, thereby reducing the risk of the atomized disinfectant in the disinfection chamber 110 entering the external environment through the delivery channel 710.

[0065] In this embodiment, the first base 100 is equipped with a first lifting mechanism 140 for adjusting the height of the conveyor belt 200, the second base 500 is equipped with a second lifting mechanism 520 for adjusting the height of the entry conveyor belt 600, and the third base 700 is equipped with a third lifting mechanism 720 for adjusting the height of the delivery conveyor belt 800. The heights of the conveyor belt 200, the entry conveyor belt 600, and the delivery conveyor belt 800 are adjustable, making them convenient for adapting to existing logistics sorting equipment.

[0066] Specifically, the first machine base 100 also includes a first base 150 and a first mounting base 160. The conveyor belt 200 is mounted on the first mounting base 160. The first lifting mechanism 140 includes a first screw, a first screw nut, and a first motor. The first screw is vertically arranged and connected to the first mounting base 160. The first screw nut is pivotally connected to the first base 150. The first screw and the first screw nut are threadedly connected. The first motor is arranged on the first base 150 and its output shaft is connected to a gear. The gear engages with the first screw nut. When the motor starts, the gear engagement drives the first screw nut to rotate. The first screw nut rotates relative to the first screw, causing the first screw to move vertically. The above structure realizes the height adjustment function of the conveyor belt 200 and has a simple structure.

[0067] Specifically, the motor drives the first lead screw nut to rotate via a gear, thereby adjusting the first lead screw's position vertically, thereby adjusting the conveyor belt 200 on the first mounting base 160 vertically relative to the first base 150. Specifically, four first lifting mechanisms 140 are provided, and the four first lifting mechanisms 140 are respectively connected to the left and right sides of the front and rear ends of the first mounting base 160.

[0068] It is conceivable that the first mounting seat 160 can also be vertically slidably set on the first base 150 by means of guide pillars and guide sleeves, and then a first lifting structure is used to adjust the position of the first mounting seat 160 relative to the first base 150.

[0069] It is conceivable that the first lifting mechanism 140 can also be other structures and is not limited to the above embodiments. For example, the first mounting seat 160 is slidably set on the first base 150 through guide columns and guide sleeves. At this time, the first lifting mechanism 140 can also be a hydraulic lifting mechanism, a gear rack lifting mechanism, etc.

[0070] Specifically, the second machine base 500 includes a second base 530 and a second mounting base 540. The conveyor belt 600 is mounted on the second mounting base 540. The second mounting base 540 is vertically slidably arranged on the second base 530. The second lifting mechanism 520 includes a second lead screw, a second lead screw nut and a second motor. The second lead screw is vertically arranged and connected to the second mounting base 540. The second lead screw nut is pivotally connected to the second base 530. The second lead screw is threadedly connected to the second lead screw nut. The second motor is arranged on the second base 530 and its output shaft is connected to a gear. The gear engages with the second lead screw nut. When the second motor is started, the gear engagement drives the second lead screw nut to rotate. The second lead screw nut rotates relative to the second lead screw, causing the second lead screw to move vertically. The above structure realizes the height adjustment function of the conveyor belt 600 and has a simple structure.

[0071] Specifically, the second mounting seat 540 is vertically connected with a guide column, and the second base 530 is connected with a guide sleeve. The guide column and the guide sleeve are slidably matched, so that the second mounting seat 540 is vertically slidably arranged relative to the second base 530.

[0072] It is conceivable that the second mounting seat 540 may further be provided with a slider portion, and a slide groove portion may be provided vertically on the second base 530, with the slider portion being slidably connected to the slide groove portion, so that the second mounting seat 540 can be vertically slidably disposed on the second base 530. It is conceivable that the second lifting mechanism 520 may also be other structures, such as a hydraulic lifting mechanism, a rack and pinion lifting mechanism, etc.

[0073] Similarly, the height adjustment method of the delivery conveyor belt 800 is the same as that of the entry conveyor belt 600, which will not be described here.

[0074] In this embodiment, the conveyor belt 200 can be adjusted to an angle of inclination relative to the horizontal plane. With the above-described structure, when the conveyor belt 200 is adjusted to an inclination, when the logistics box on the conveyor belt 200 contacts the offset mechanism 400 and is displaced relative to the conveyor belt 200, the friction on the lower surface of the logistics box is reduced. The offset mechanism 400 reduces the force required to displace the logistics box relative to the conveyor belt 200, facilitating displacement of the logistics box relative to the conveyor belt 200.

[0075] Specifically, the four first lifting mechanisms 140 are used to adjust the heights of the front and rear ends, the left and right sides of the first mounting base 160 respectively, so as to achieve the above functions.

[0076] The upper end of the first screw is pivotally connected to the first mounting base 160. Optionally, in some embodiments, when the heights of the two first screws on the left and right sides are different, the first mounting base 160 and the conveyor belt 200 thereon can be tilted in the left-right direction, resulting in different heights at the left and right ends of the conveyor belt 200. In this case, the adaptive offset mechanism 400 causes the logistics box to shift in the left-right direction relative to the conveyor belt 200.

[0077] Optionally, in some embodiments, when the heights of the two front first screws differ from the heights of the two rear first screws, the first mounting base 160 and the conveyor belt 200 thereon can be tilted along the length direction, resulting in different heights at the front and rear ends of the conveyor belt 200. In this case, the adaptive offset mechanism 400 enables the logistics box to move forward and backward relative to the conveyor belt 200.

[0078] Alternatively, in some embodiments, when the heights of the four first lead screws are all different, the first mounting base 160 and the conveyor belt 200 thereon are tilted, with the four heights on the left and right sides at the front and rear ends having their highest and lowest points. In this case, the offset mechanism 400 can be adapted to propel the logistics box sideways and forward and backward relative to the conveyor belt 200. In this case, the first lead screws are connected to the first mounting base 160 via a universal joint or a ball joint structure.
