[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] In the fruit and vegetable packaging industry, the traditional method involves using a conveyor to directly transport the fruits and vegetables into the packaging box. However, current fruit and vegetable conveyors have a certain drop from the discharge port to the bottom of the box, and the larger the box size, the greater the drop. During the downward conveying process, the fruits and vegetables are prone to rolling off the sides of the conveyor, causing damage to some of them and affecting the efficiency of packing.

[0035] Based on this, please refer to Figure 1 , Figure 2 and Figure 3 The fruit and vegetable packing system 1000 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. This fruit and vegetable packing system 1000 can prevent fruits and vegetables from rolling and being damaged during transportation and packing, reducing the rate of spoiled fruit and improving packing efficiency.

[0036] Figure 1 This is a first-view schematic diagram of the fruit and vegetable packing system 1000 provided in an embodiment of the present invention; Figure 2 This is a schematic diagram from a second perspective of the fruit and vegetable packing system 1000 provided in an embodiment of the present invention; Figure 3 This is a third-view schematic diagram of the fruit and vegetable packing system 1000 provided in an embodiment of this utility model, as shown below. Figure 1 , Figure 2 and Figure 3 As shown, the fruit and vegetable packing system 1000 in this embodiment includes a lifting conveyor 100, a vertical conveyor 200, and a movable baffle 300. The lifting conveyor 100 includes an inlet 121 and an outlet 122, with the inlet 121 positioned lower than the outlet 122. The vertical conveyor 200 is located at the outlet 122 and receives the fruits and vegetables transported from the lifting conveyor 100 to the outlet 122, then conveys them downwards for packing. The movable baffle 300 is located below the outlet 122 and is positioned close to the vertical conveyor 200; it prevents the fruits and vegetables on the vertical conveyor 200 from falling off. By using the lifting device, the fruits and vegetables can be conveyed to a certain height, facilitating subsequent packing. By installing a movable baffle 300 on the side of the vertical conveyor 200, the movable baffle 300 can prevent the fruits and vegetables from rolling off during the process of receiving them at the discharge port 122 and transporting them downwards for packing. This reduces the spoilage rate and improves packing efficiency.

[0037] Specifically, please refer to Figure 1In this embodiment, the lifting and conveying device 100 includes a frame 110 and a second conveyor belt 120. The second conveyor belt 120 is connected to the frame 110 via a drive mechanism. One end of the conveyor belt is a feed inlet 121, and the other end is a discharge outlet 122. A movable baffle 300 is connected to the frame 110. The second conveyor belt 120 is powered by a drive component 420, such as a motor. To ensure smoother transport of fruits and vegetables, the second conveyor belt 120 in this embodiment is inclined at a 15° angle to the ground. Of course, the second conveyor belt 120 can be inclined at other angles to the ground, such as 10°, 17°, 30°, etc., and is not limited here. As long as the second conveyor belt 120 can smoothly transport the fruits and vegetables entering the second conveyor belt 120 from the feed inlet 121 to the vertical conveying device 200, it is acceptable.

[0038] To offset the impact of fruits and vegetables and to hold them in place, preventing them from sliding down during the lifting process of the second conveyor belt 120, the second conveyor belt 120 in this embodiment is a corrugated conveyor belt. The concave areas of the corrugations can catch the fruits and vegetables to prevent them from rolling off during lifting. At the same time, when the fruits and vegetables fall into the corrugated belt, the raised, soft waves can effectively mitigate the impact of gravity. Of course, the second conveyor belt 120 can also be designed with other shapes or structures such as serrated edges, as long as it can buffer and prevent fruits and vegetables from falling. The specific shape is not limited here.

[0039] After the fruits and vegetables are transported to the discharge port 122, they will roll onto the vertical conveyor 200. Due to inertia, the fruits and vegetables may continue to roll after landing on the vertical conveyor 200 and may eventually fall off. To prevent the fruits and vegetables from rolling off the vertical conveyor 200, a movable baffle 300 is provided near the vertical conveyor 200 in this embodiment.

[0040] Specifically, please refer to Figure 1 and Figure 2 In this embodiment, the movable baffle 300 includes a baffle 310, a first roller 320, a second roller 330, and a counterweight 340. Both the first roller 320 and the second roller 330 are connected to the lifting and conveying device 100. The first roller 320 is positioned below the discharge port 122, and the second roller 330 is positioned near the inlet 121. The baffle 310 is drivenly connected to the first roller 320 and the second roller 330. A portion of the baffle 310 is close to the vertical conveying device 200 to prevent fruits and vegetables from falling off the vertical conveying device 200. The counterweight 340 is connected to the end of the baffle 310 furthest from the vertical conveying device 200. By varying the weight of the counterweight 340, the movable baffle 300 can move up and down along the conveying direction of the vertical conveying device 200. When the counterweight 340 drives the baffle 310 to move up and down, the rollers rotate, providing assistance to the movement of the baffle 310, thus facilitating its movement. The 300 activity curtain has a simple structure, is easy to install, and has a low cost.

[0041] Of course, the number of rollers can be three, four, or more, and is not limited here. The position of the rollers is set according to specific circumstances and labor-saving requirements, and is not limited here, as long as the curtain 310 is close to the vertical conveyor 200 and can play a blocking role to prevent fruits and vegetables from rolling off the vertical conveyor 200.

[0042] In addition, the movable curtain 300 can also be a retractable roller shutter or other means to achieve the effect of vertical belt blocking fruit, so as to prevent the fruits and vegetables on the vertical conveyor 200 from rolling off, and there is no limitation here.

[0043] As more and more fruits and vegetables accumulate in the fruit box, their surface height gradually increases. To adapt this, the distance between the contour-following claw 222 and the surface of the fruits and vegetables in the box is adjusted to maintain a reasonable distance and prevent the fruits and vegetables from being damaged due to excessive distance from the surface. Please refer to [link / reference needed]. Figure 3 and combined Figure 1 and Figure 2 The vertical conveying device 200 in this embodiment also includes a lifting assembly 400, which is connected to the conveying frame 210 and is used to drive the conveying frame 210 to move up and down.

[0044] Specifically, to simplify the structure and reduce costs, please refer to Figure 3 and combined Figure 1 and Figure 2 In this embodiment, the lifting assembly 400 includes a connecting frame 410, a driving component 420, a connecting shaft 430, a gear 440, and a rack 450. The connecting frame 410 is connected to the conveying frame 210, the connecting shaft 430 is fixedly connected to the connecting frame 410, the gear 440 is sleeved on the connecting shaft 430, the driving component 420 is connected to the connecting shaft 430 and is used to drive the gear 440 to rotate, the gear 440 meshes with the rack 450, and the rack 450 is used to be mounted on an external fixed frame; the extending direction of the rack 450 is the same as the conveying direction of the vertical conveying device 200; the gear 440 can move along the rack 450. Of course, the lifting assembly 400 can also be designed with other structures, such as casters, as long as it can realize that the lifting assembly 400 adjusts the height of the vertical conveying device 200 according to the surface height of the fruits and vegetables in the fruit box. The specific design is not limited here.

[0045] To prevent accidental movement of gears 440 and rack 450, the drive component 420 in this embodiment is a clutch motor. The clutch motor can precisely control the motor's start and stop, as well as its speed and direction of movement, and can prevent the motor from continuing to move under unexpected circumstances, thereby avoiding accidents. Of course, the drive component 420 can also be other motors or similar devices, and is not limited here.

[0046] To prevent the gear 440 and rack 450 from moving back and forth, the lifting assembly 400 in this embodiment also includes a limiting guide rail 460 and a slider 470. The slider 470 is slidably connected to the limiting guide rail 460, which is disposed on the conveyor frame 210. The slider 470 is connected to the connecting frame 410. The limiting guide rail 460 and slider 470 serve as an auxiliary limiting element. Of course, limiting elements can also be set in other positions to ensure that the conveyor frame 210 moves only in the conveying direction and does not sway.

[0047] To cushion the fruits and vegetables rolling from the conformal claws 222 into the fruit box, a brush roller 240 is provided at the bottom end of the first conveyor belt 221 in this embodiment. The brush roller 240 plays a certain role in slowing down the flow.

[0048] Please continue reading. Figure 3 and combined Figure 1 and Figure 2 In this embodiment, the vertical conveying device 200 also includes a disc packing device 230, which is connected to the bottom end of the first conveyor belt 221. The disc packing device 230 can be designed with a multi-layer buffer structure, such as using a soft and elastic material for the fruit drop tray and incorporating a buffered, inclined rubber sheet to reduce the force on the fruits and vegetables as they fall into the fruit box, thereby reducing damage. In this embodiment, the disc packing device 230 includes a geared motor, a transmission device, a fan-shaped rubber sheet, a fruit drop disc, a fruit-contacting brush, a limit switch, a fruit-blocking brush, and a long fruit drop rubber sheet. The geared motor provides rotational power to the transmission device, which provides coaxial differential speed between the upper fan-shaped rubber sheet and the fruit drop disc, allowing them to rotate at different speeds. Five fan-shaped rubber sheets are connected to the transmission device via support rods. Each rubber sheet has an effective arc of 110°. The fruit-dropping disc is also connected to the transmission device. The disc has two evenly distributed fruit-dropping notches with an arc of 65°. A fruit-touching brush and a limit switch are installed below the disc. Two long rubber sheets are fixed to the two notches on the disc. Two fruit-blocking brushes are installed at the two notches to prevent fruits and vegetables from falling through.

[0049] Figure 4 For a schematic diagram of the vertical conveying device 200 provided in an embodiment of this utility model, please refer to [link / reference]. Figure 4 and combined Figure 3To better support fruits and vegetables, the vertical conveying device 200 in this embodiment includes a conveyor frame 210 and a contoured finger belt 220. The contoured finger belt 220 is installed on the conveyor frame 210 and can convey fruits and vegetables vertically relative to the conveyor frame 210. Specifically, the contoured finger belt 220 includes a first conveyor belt 221 and multiple contoured fingers 222. The multiple contoured fingers 222 are spaced apart on the first conveyor belt 221 and are used to support fruits and vegetables. The first conveyor belt 221 drives the multiple contoured fingers 222 to move up and down cyclically, so that after the received fruits and vegetables are placed in the fruit box, new fruits and vegetables can be received, realizing cyclical operation. The spacing between the multiple contoured fingers 222 is greater than the diameter of the fruits and vegetables to prevent fruits and vegetables from getting stuck between adjacent contoured fingers 222.

[0050] To better support fruits and vegetables, please place them down more gently. Figure 5 , Figure 5 This is a schematic diagram of the contouring claw 222 provided in an embodiment of the present invention. In this embodiment, each contouring claw 222 includes a first finger segment 2221, a second finger segment 2222, and a third finger segment 2223 connected in sequence. The first finger segment 2221 is connected to the first conveyor belt 221 and has a first angle with the Y direction; the second finger segment 2222 has a second angle with the Y direction; and the third finger segment 2223 has a third angle with the Y direction. The first angle is greater than the second angle, the second angle is greater than the third angle, and the first angle is an acute angle. The length of the first finger segment 2221 is greater than the length of the second finger segment 2222, and the length of the second finger segment 2222 is greater than the length of the third finger segment 2223. This design of the claws not only allows them to support heavier fruits and vegetables, but also prevents them from directly impacting the fingertips when they enter the contoured claws 222 from the outlet 122. Instead, the fruits and vegetables come into contact with the third finger segment 2223, effectively preventing soft fruits and vegetables from being punctured by the fingertips. The fruits and vegetables will also be squeezed at the entrance edge of the contoured claws 222. The contoured claws 222 have a three-section curved design with a diameter that tapers from bottom to top, which reduces the pressure on the fruit and vegetables from the fingertips.

[0051] Specifically, in this embodiment, from the first finger segment 2221 to the third finger segment 2223, the diameter gradually tapers from 20mm at the bottom to 8mm upwards. The first finger segment 2221 is at a 75° angle to the conveying direction of the vertical conveying device 200 and has a length of 83mm; the second finger segment 2222 is at a 55° angle to the conveying direction of the vertical conveying device 200 and has a length of 41mm; the third finger segment 2223 is at a 25° angle to the conveying direction of the vertical conveying device 200 and has a length of 30mm. Of course, the diameter, length, and included angle of the first finger segment 2221, the second finger segment 2222, and the third finger segment 2223 can also be other values, depending on the actual fruits and vegetables being conveyed, and are not limited here. According to the principle of contouring, in this embodiment, the tilt angle of the first finger segment 2221 is 70° to 85°, the tilt angle of the second finger segment 2222 is 50° to 65°, and the tilt angle of the third finger segment 2223 is 20° to 30°.

[0052] Of course, the contouring claw 222 may also include two, four or more finger segments, depending on the actual fruits and vegetables being transported, and is not limited here.

[0053] Furthermore, to prevent the claws from squeezing and damaging fruits and vegetables, the contoured claws 222 in this embodiment are made of materials with good toughness and elasticity, such as PU material or rubber. Specifically, the contoured claws 222 in this embodiment are made of PU material with a Shore hardness of 60° to 65°. PU material not only has good toughness but also good resilience and a long service life. Of course, other materials can also be used, and this is not limited here.

[0054] The working principle of the fruit and vegetable packing system 1000 provided in this embodiment is as follows:

[0055] When fruits and vegetables fall from the previous process onto the second conveyor belt 120 of the lifting conveyor mechanism, the wavy conveyor belt effectively offsets the impact of the fruits and vegetables and holds them in place, preventing them from sliding down during the lifting process. The fruits and vegetables are conveyed to the discharge port 122 and then slide onto the contoured claws 222 of the contoured claw belt 220. When the fruits and vegetables roll unstablely on the claws, the movable baffle 300 will block the fruits and vegetables, preventing them from falling off the contoured claw 222 belt. Fruits and vegetables are slowly lowered below the vertical conveyor and slide into the rotating brush roller 240. The brush roller 240 effectively reduces the speed of the fruits and vegetables and separates them to prevent collisions. The fruits and vegetables are gently transferred to the upper fan-shaped rubber sheet of the disc packing mechanism. As the fan-shaped rubber sheet rotates on the fruit-dropping disc, when it rotates to the notch of the disc, the weight of the fruits and vegetables will press the fan-shaped rubber sheet into the long fruit-dropping rubber sheet. As the differential rotation continues, the tail of the fan-shaped rubber sheet will be completely attached to the long fruit-dropping rubber sheet, and the fruits and vegetables will slowly slide onto it. When the long fruit-dropping rubber sheet rotates to the low point of the large box, the fruits and vegetables on it will slide into the large box to fill the low point. When the fruits and vegetables in the large box reach a certain height, the fruit-touching brush will be obstructed by the fruits and vegetables and rotate backward, triggering the limit switch. After receiving the limit switch trigger signal, the drive component 420 of the lifting component 400 will drive the vertical conveying mechanism and the disc packing device 230 to rise a short distance and continue packing. This process is repeated until the large box is full, triggering the full frame sensor of the photoelectric sensor, stopping the operation, and completing the fruit and vegetable packing.

[0056] In summary, the fruit and vegetable packing system 1000 includes a lifting conveyor 100, a vertical conveyor 200, and a movable baffle 300. The lifting conveyor 100 includes an inlet 121 and an outlet 122, with the inlet 121 positioned lower than the outlet 122. The vertical conveyor 200 is located at the outlet 122 and receives the fruits and vegetables transported from the lifting conveyor 100 to the outlet 122, then conveys them downwards for packing. The movable baffle 300 is positioned below the outlet 122 and close to the vertical conveyor 200; it prevents fruits and vegetables from falling off the vertical conveyor 200. By incorporating the lifting device, fruits and vegetables can be conveyed to a certain height, facilitating subsequent packing. By installing a movable baffle 300 on the side of the vertical conveyor 200, the movable baffle 300 can prevent the fruits and vegetables from rolling off during the process of receiving them at the discharge port 122 and transporting them downwards for packing. This reduces the spoilage rate and improves packing efficiency.

[0057] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
