Description

Technical Field

[0001] This utility model relates to the field of lychee packaging equipment technology, and in particular to a conveying device used in lychee packaging equipment. Background Technology

[0002] With rapid technological advancements and a significant improvement in people's living standards, consumers are increasingly demanding higher quality fruits. To ensure fruits are presented to consumers in their freshest condition, many high-end fruits are now individually packaged. Traditional transparent bags are no longer sufficient to protect fruits during transportation, easily causing them to be crushed and affecting their appearance and quality. Therefore, PVC boxes, with their inherent rigidity, are gradually becoming a new packaging choice, providing more reliable protection and ensuring fruits remain intact even during long-distance transport.

[0003] Lychee, a renowned fruit of Lingnan (southern China), is a precious gift from nature. Rich in nutrients such as vitamin C, vitamin A, vitamin B, folic acid, glucose, sucrose, protein, fat, fruit acids, and various minerals, it boasts extremely high nutritional value and is widely loved. However, preserving lychee remains an ancient and thorny problem. As early as the Tang Dynasty, there was the famous story of "A rider in the dust brings a smile to the imperial concubine's face, but no one knows it's lychees arriving," illustrating the immense effort put into ensuring Yang Guifei could enjoy fresh lychees. The saying, "If separated from the branch, its color changes in a day, and its taste changes in three days," vividly depicts the difficulty of preserving lychees.

[0004] However, with the advancement of modern technology, this age-old problem has many effective solutions. For high-end lychees, individual packaging in hard-shell PVC boxes is now common. This packaging method not only provides solid physical protection for the lychees but also isolates them from external air and moisture to a certain extent, reducing the risk of oxidation and spoilage. During the packaging process, nitrogen is also injected into the box. Nitrogen is an inert gas that effectively inhibits the respiration of lychees and the growth and reproduction of microorganisms, further extending the shelf life of the lychees. Finally, the sealed lychees are placed in a cold storage for freezing. The low temperature environment slows down the metabolism of the lychees, keeping them fresh for a longer period of time.

[0005] However, packaging lychees individually is an extremely tedious and monotonous task, requiring a significant amount of manpower and time. To improve packaging efficiency and quality while reducing labor costs, the assistance of mechanical equipment is crucial. By introducing advanced automated packaging equipment, lychees can be packaged quickly and accurately, not only improving packaging efficiency but also ensuring packaging consistency and stability, providing strong support for lychee preservation and sales. Utility Model Content

[0006] This invention overcomes the shortcomings of the prior art and provides a conveying device for lychee packaging equipment. It is equipped with a moving feeding component. Through the reciprocating motion of the moving table, lychees can be filled into the slots of the packaging box row by row, realizing continuous and efficient packaging of lychees. Compared with manual packaging, it greatly improves the packaging speed, reduces the intensity of manual labor, and improves the overall production efficiency, which can meet the needs of large-scale lychee packaging.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A conveying device for lychee packaging equipment includes a hopper, a conveying assembly, a rotating docking assembly, and a moving unloading assembly; the conveying assembly is used to carry lychees out of the hopper, and the conveying assembly is provided with conveying rollers, which are provided with a number of roller body arc grooves. The roller body arc grooves of two adjacent conveying rollers form a circular groove, and a lychee can be placed in the circular groove. The mobile unloading assembly includes a mobile power component and a mobile stage, wherein the mobile power component drives the mobile stage to reciprocate relative to the docking assembly. Lychee packaging boxes with multiple slots are placed at the exit of the moving feeding component. The slots are arranged in a square array, forming several rows of equally spaced slots. Lychees fall from the output end of the conveying component into the docking component, which then transports the lychees to the corresponding feeding rails on the moving platform. Each feeding rail transports one lychee at a time, and the lychees eventually fall from the feeding rail exit into the lychee packaging box. Several lychees falling at once fill one row of slots. Then the moving platform moves the distance between two slots, and several lychees falling a second time fill the second row of slots. This process continues until all the slots on a lychee packaging box are filled. The lychee packaging box is then sent to the next process for nitrogen filling and sealing.

[0008] Furthermore, an end baffle is rotatably connected to the outlet of the feeding rail. The end baffle is controlled by an end movable cylinder. When the lychee rolls down from the feeding rail, the end baffle closes the opening of the feeding rail, so that the lychee is blocked when it reaches the end baffle. Then the end baffle opens, so that the lychee rolls down from the opening of the feeding rail into the lychee packaging box.

[0009] Furthermore, the rotating docking assembly includes a docking motor connected to a docking track plate, which is rotatably connected to the output end of the conveying assembly. The docking motor sets the angle of rotation of the docking track plate for each docking based on the distance between the moving platform and the conveying assembly, so that the lower end of the docking track plate can abut against the upper surface of the moving platform, thereby allowing the packaged lychees to smoothly transition from the conveying assembly to the moving platform via the docking track plate.

[0010] Furthermore, the docking track plate includes a docking rotating shaft, and the docking track plate is also provided with a number of docking rails. When the docking track plate rotates upward, the docking rails correspond one-to-one with the roller body arc grooves. When the docking track plate rotates downward, the docking rails correspond one-to-one with the feeding rails.

[0011] Furthermore, the docking track plate is provided with a docking rounded corner at one end near the roller body arc groove. When the docking track plate moves upward, the docking rounded corner abuts against the outer circumference of the conveying roller.

[0012] Furthermore, a vertical vibration machine is installed below the hopper, and the lower end of the conveying assembly is located inside the hopper.

[0013] Furthermore, a sorting and return assembly and a vision inspection system are provided above the conveying assembly, with the vision inspection system located between the sorting and return assembly and the hopper; The vision inspection system is used to detect whether there are lychees on each row of roller grooves. The selection and return component is used to pick up the lychees on the roller grooves of a row with insufficient lychees and make them roll into the return hopper.

[0014] Furthermore, the selection and recirculation assembly includes a recirculation base, a recirculation rocker connected to the recirculation base, a rocker rotating rod in the middle of the recirculation rocker, a rocker connecting part and a rocker insert on both sides of the rocker rotating rod, a recirculation power component at the upper end of the recirculation base, the output end of the recirculation power component connected to a fisheye connector, and the fisheye connector connected to the rocker connecting part. When the return power component pushes the rocker connector downward, the rocker block rises; when the return power component pulls the rocker connector upward, the rocker connector is pressed downward.

[0015] Furthermore, several rocker blocks are provided, and each rocker block corresponds to a groove on the roller body.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. A moving feeding component is installed. Through the reciprocating motion of the moving table, lychees can be filled into the slots of the packaging box row by row, realizing continuous and efficient packaging of lychees. Compared with manual packaging, it greatly improves the packaging speed, reduces the intensity of manual labor, and improves the overall production efficiency, which can meet the needs of large-scale lychee packaging.

[0017] 2. The end baffle at the outlet of the feeding rail can be controlled by the end movable cylinder to open and close. When the lychees fall, the end baffle closes to block the lychees and prevent them from jumping out of the packaging box due to the conversion of potential energy into kinetic energy. When the outlet of the feeding rail is aligned with the pit, the end baffle opens to allow the lychees to fall accurately into the pit, ensuring the integrity and stability of the lychee packaging.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] like Figures 1 to 9As shown, a conveying device for lychee packaging equipment includes a hopper 1, a conveying assembly 2, a rotating docking assembly 4, and a moving unloading assembly 5. The conveying assembly 2 is used to carry lychees out of the hopper 1. The conveying assembly 2 is equipped with a conveying motor 201, which is connected to a chain. Multiple conveying rollers 202 are provided on the chain. When the chain rotates, it drives the conveying rollers 202 to move along the chain. The conveying rollers 202 are provided with several roller body arc grooves 2021. The roller body arc grooves 2021 of two adjacent conveying rollers 202 form a circular groove, which can hold one lychee. If there is already one lychee in the circular groove, other lychees cannot fall into the circular groove when passing over it, so that the lychees can be stably placed during the conveying process, avoiding mutual squeezing and collision.

[0022] The conveying component 2 is set at an angle, with the lower end inserted into the hopper 1 and the higher end connected to the rotating docking component 4. A vertical vibration machine 101 is set below the hopper 1, and the lower end of the conveying component 2 is set inside the hopper 1. The vertical vibration machine 101 vibrates the lychees in the hopper 1, so that the lychees are not tightly squeezed together, and the lychees can be smoothly carried by the conveying component 2.

[0023] The mobile feeding component 5 includes a mobile power component 501 and a mobile stage 502. The mobile power component 501 drives the mobile stage 502 to reciprocate relative to the docking component 4. The lychee packaging box with multiple slots is placed at the outlet of the mobile feeding component 5. The multiple slots are arranged in a square array to form several rows of equally spaced slots.

[0024] Lychees fall from the output end of the conveying component 2 into the docking component 4. The docking component 4 then conveys the lychees to the corresponding feeding rails 5021 on the moving table 502. Each feeding rail 5021 conveys one lychee at a time. The lychees eventually fall from the outlet of the feeding rail 5021 into the lychee packaging box. Several lychees falling at once fill one row of slots. Then the moving table 502 moves the distance between two slots, and several lychees falling a second time fill the second row of slots. This process continues until all the slots on a lychee packaging box are filled. The lychee packaging box is then sent to the next process for nitrogen filling and sealing.

[0025] In this embodiment, the moving power component 501 is a belt-driven moving module. Because the moving power component 501 drives the moving platform 502 to move back and forth, the lychees can be placed into the lychee packaging box row by row, depending on the different lychee packaging boxes.

[0026] An end baffle 5023 is rotatably connected to the outlet of the feeding rail 5021. The end baffle 5023 is controlled by an end movable cylinder. When the lychee rolls down from the feeding rail 5021, the end baffle 5023 closes the opening of the feeding rail 5021, so that the lychee is blocked at the end baffle 5023. Then the end baffle 5023 opens, so that the lychee rolls from the opening of the feeding rail 5021 into the lychee packaging box. When the lychee falls from the height of the feeding rail 5021, its potential energy is converted into kinetic energy, which allows the lychee to fall. In order to prevent the lychee from falling into the lychee packaging box and then bouncing out, the end baffle 5023 is set. The end baffle 5023 can block the lychee. The end baffle 5023 is opened only when the outlet of the feeding rail 5021 is aligned with the pit of the lychee packaging box, so that the lychee can fall accurately into the pit.

[0027] The rotating docking assembly 4 includes a docking motor 401, which is connected to a docking track plate 402. The docking track plate 402 is rotatably connected to the output end of the conveying assembly 2. The docking motor 401 sets the angle of rotation of the docking track plate 402 for each docking according to the distance between the moving platform 502 and the conveying assembly 2, so that the lower end of the docking track plate 402 can abut against the upper surface of the moving platform 502, thereby allowing the packaged lychees to smoothly transition from the conveying assembly 2 through the docking track plate 402 to the moving platform 502.

[0028] The docking track plate 402 includes a docking rotating shaft 4021 and a number of docking rails 4023. When the docking track plate 402 moves upward, the docking rails 4023 correspond one-to-one with the roller body arc grooves 2021. When the docking track plate 402 moves downward, the docking rails 4023 correspond one-to-one with the unloading rails 5021.

[0029] The end of the docking track plate 402 near the roller body arc groove 2021 is also provided with a docking rounded corner 4022. When the docking track plate 402 moves upward, the docking rounded corner 4022 abuts against the outer circumference of the conveying roller 202. Therefore, when the lychee falls from the conveying roller 202 to the docking track 4023, the left and right sides of the lychee will be protected by the two sides of the docking track 4023, so that the lychee will not fall from the side.

[0030] A sorting and return assembly 3 and a vision inspection system are installed above the conveying assembly 2. The vision inspection system is located between the sorting and return assembly 3 and the hopper 1. The vision inspection system is used to detect whether there are lychees on each row of roller grooves 2021. The sorting and return assembly 3 is used to pick up the lychees on the roller grooves 2021 where there are not enough lychees, so that they roll into the return hopper 1. When the roller grooves 2021 are full of lychees, the sorting and return assembly 3 does not operate, so that the lychees can be smoothly transferred. The lychees are conveyed to the outlet of the conveying component 2. In this way, the number of lychees conveyed by the conveying component 2 in each batch is consistent with the number of roller grooves 2021 set on the conveying roller 202. The number of roller grooves 2021 is consistent with the number of slots in a row on the lychee packaging box. In this way, each time the conveying component 2 outputs lychees, it fills a row of slots on the lychee packaging box. As the moving table 502 moves, it can fill all the slots in the lychee packaging box, thus ensuring that each lychee packaging box is full of lychees.

[0031] The selected reflux assembly 3 includes a reflux base 301, a reflux rocker 303 rotatably connected to the reflux base 301, a rocker rotating rod 3031 in the middle of the reflux rocker 303, a rocker connecting part 3032 and a rocker insert 3033 respectively on both sides of the rocker rotating rod 3031, and a reflux power component 302 at the upper end of the reflux base 301. In this embodiment, the reflux power component 302 is a cylinder or an electric cylinder. The output end of the reflux power component 302 is connected to a fisheye connector 3021, and the fisheye connector 3021 is connected to the rocker connecting part 3032. When the reflux power component 302 pushes the rocker connecting part 3032 downward, the rocker insert 3033 is raised. When the reflux power component 302 pulls the rocker connecting part 3032 upward, the rocker connecting part 3032 is pressed downward. Several rocker inserts 3033 are provided, and each rocker insert 3033 corresponds to a roller body arc groove 2021.

[0032] During operation, the vertical vibration machine 101 below the hopper 1 vibrates the lychees in the hopper to prevent the lychees from being squeezed and clumped together, so that the lychees can be smoothly carried up by the conveying roller 202 of the conveying component 2 and fall into the roller body arc groove 2021.

[0033] The rocker block 3033 of the selection return assembly 3 is initially in a tilted state. The vision inspection system detects the number of lychees on each row of roller arc grooves 2021. If the number is insufficient, the return power component 302 of the selection return assembly 3 is activated, pushing the rocker connecting part 3032 to make the rocker block 3033 fall down and tilt up quickly, picking up the lychees on the row of roller arc grooves 2021 with insufficient quantity and rolling them into the return hopper 1. If the quantity is sufficient, the selection return assembly 3 does not activate.

[0034] The conveying component 2 transports lychees to the output end. The docking motor 401 of the rotating docking component 4 adjusts the rotation angle of the docking track plate 402 according to the distance between the moving platform 502 and the conveying component 2, so that the docking rail 4023 of the docking track plate 402 corresponds to the roller body arc groove 2021 and the unloading rail 5021. The lychees are transferred from the conveying roller 202 to the unloading rail 5021 via the docking rail 4023.

[0035] After the lychees enter the feeding rail 5021, the end baffle 5023 first closes to block the lychees. When the outlet of the feeding rail 5021 is aligned with the pit of the lychee packaging box, the end baffle 5023 opens and the lychees fall into the pit. The moving power unit 501 drives the moving table 502 to move, so that the lychees fill each row of pits in the packaging box in sequence until the entire packaging box is full, and then it is sent to the nitrogen filling and sealing process.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
