Description

Technical Field

[0001] This application relates to the field of fruit and vegetable sorting technology, and in particular to a fruit and vegetable packing machine and fruit and vegetable sorting equipment. Background Technology

[0002] To reduce floor space, fruit and vegetable sorting equipment typically utilizes vertical space, staggering the sorting and conveying routes along the vertical axis. This necessitates downward transport of fruits and vegetables during the boxing process. Fruit and vegetable boxing machines are commonly used automated boxing equipment in fruit and vegetable sorting. However, existing conveying methods, whether simple free fall or crude mechanical conveying, struggle to precisely control the vertical movement speed and posture of the fruits and vegetables. This makes them susceptible to damage during descent or transfer due to excessive impact, collisions, or hard contact with the receiving equipment structure. Summary of the Invention

[0003] One objective of this application is to provide a fruit and vegetable packing machine and a fruit and vegetable sorting device to solve the technical problem that fruits and vegetables are easily damaged during the falling or transfer process due to excessive impact, mutual collision, or hard contact with the receiving device structure.

[0004] This application provides a fruit and vegetable packing machine, including: frame; The packing assembly has a fruit box at the bottom for stacking the received fruits and vegetables in a rotating direction inside the fruit box; A vertical conveying assembly is connected to both the frame and the boxing assembly. The vertical conveying assembly is located above the boxing assembly and is used to convey the fruits and vegetables to the boxing assembly at a preset speed.

[0005] The aforementioned structure utilizes a vertical conveyor assembly to control the falling speed of fruits and vegetables, preventing excessive impact from gravity-induced acceleration. Simultaneously, the rotating stacking mechanism of the packing assembly ensures that fruits and vegetables are placed stably and orderly, rather than piled up haphazardly. This achieves high efficiency and low loss during the automated packing process, effectively protecting the integrity and quality of the fruits and vegetables.

[0006] Optionally, the vertical conveying assembly includes: A first housing, wherein the first housing is provided with a receiving compartment; A vertical conveyor belt is housed within the receiving chamber, and the conveying direction of the vertical conveyor belt is vertically downward; Multiple support units are spaced apart along the length of the vertical conveyor belt and connected to the belt surface of the vertical conveyor belt. The support units are used to support a preset number of fruits and vegetables.

[0007] The above structure employs a vertical conveyor belt operating within a closed first housing, with multiple independent support units spaced at intervals on the belt surface. Each support unit is designed to hold a preset quantity (e.g., one to several) of fruits and vegetables. As the vertical conveyor belt circulates, the support units smoothly transport the fruits and vegetables in batches and quantities from a height to the bottom, effectively preventing them from being squeezed or collided with each other during the fall. Simultaneously, the spaced support units ensure that the feeding of materials to the packaging assembly is rhythmic and intermittent, avoiding instantaneous accumulation of materials.

[0008] Optionally, each of the supporting units includes a plurality of supporting fingers, which are spaced apart in the width direction of the vertical conveyor belt and connected to the belt surface of the vertical conveyor belt.

[0009] The aforementioned structure incorporates multiple support fingers spaced apart along the width of the conveyor belt into each support unit, rather than a single flat plate. These support fingers collectively form a comb-like support surface, providing stable support for the fruits and vegetables. This multi-point support finger structure better adapts to the curved surfaces of round fruits and vegetables, preventing them from rolling.

[0010] Optionally, one end of the supporting finger is connected to the surface of the vertical conveyor belt, and the other end of the supporting finger is bent and extended in the opposite direction to the movement direction of the vertical conveyor belt.

[0011] With the above structure, the other end of the supporting finger can laterally limit the fruits and vegetables, so that when the conveyor belt moves downward, it can firmly hold the fruits and vegetables, prevent them from slipping, and avoid collision with the inner wall of the first housing.

[0012] Optionally, the bottom of the first housing is provided with a side opening and a guide ramp, the guide ramp faces the side opening and is inclined downward, and the side opening is at a preset height from the packing assembly; The supporting unit is capable of placing the fruits and vegetables on the guide ramp and abutting them when it moves to the bottom of the first housing, so that the fruits and vegetables continue to move on the guide ramp at the preset speed, and releasing the fruits and vegetables when it rises and resets, so that the fruits and vegetables fall into the packing assembly through the side opening.

[0013] With the above structure, a lateral opening and an inclined guide ramp are provided at the bottom of the first housing, where the vertical conveyor belt turns. When the supporting unit lifts fruits and vegetables to this area, it does not allow the fruits and vegetables to fall directly. Instead, it first places the fruits and vegetables smoothly on the guide ramp and continues to block the fruits and vegetables from moving a short distance along the ramp at the same linear speed as the vertical conveyor belt. Subsequently, when the supporting unit begins to reset upwards, it releases the fruits and vegetables, allowing them to slide out from the lateral opening along the ramp and fall into the packaging assembly. This effectively prevents the fruits and vegetables from rolling freely on the guide ramp, reduces the impact force after the fruits and vegetables slide out from the lateral opening, and thus reduces the damage rate of the fruits and vegetables.

[0014] Optionally, the vertical conveying assembly further includes a buffer brush disposed at the lateral opening, the buffer brush being used to reduce the speed at which the fruits and vegetables leave the lateral opening.

[0015] With the above structure, a row of soft, cushioning brushes is installed along the path of the fruits and vegetables as they slide out of the side opening. As the fruits and vegetables leave the guide ramp, they pass through these brushes. The flexible bristles of the cushioning brushes provide slight resistance to the sliding fruits and vegetables, effectively reducing their speed as they finally fall into the packing assembly, further reducing the impact force after they slide out of the side opening.

[0016] Optionally, the vertical conveying assembly further includes: A roller brush is disposed in the lateral opening; A roller brush driver is installed in the first housing and connected to the roller brush. The roller brush driver is used to drive the roller brush to rotate. The rotation direction of the roller brush is the same as the running direction of the vertical conveyor belt.

[0017] With the above structure, the rotation direction of the roller brush is the same as the downward running direction of the vertical conveyor belt. When fruits and vegetables move close to the side opening, they are blocked by the bristles of the roller brush, and then pushed until they are pushed out of the side opening, effectively reducing the speed at which the fruits and vegetables finally fall into the packing assembly, and further reducing the impact force after the fruits and vegetables slide out of the side opening.

[0018] Optionally, the packing assembly includes: A rotating tray for holding fruits and vegetables, wherein the vertical conveying component is offset relative to the axis of the rotating tray, the rotating tray includes an upper tray and a lower tray arranged coaxially, the upper tray has at least two partitions around the axis, the lower tray has a hollow area offset relative to the axis, and the area directly below the lower tray is used to place fruit boxes. A rotary drive mechanism is connected to the upper plate and the lower plate respectively, and is used to drive the upper plate and the lower plate to rotate at different speeds, wherein the rotational speed of the upper plate is greater than that of the lower plate; The upper plate can drive the fruits and vegetables to rotate relative to the lower plate. Whenever one of the partitions rotates to align with the hollow area, the fruits and vegetables in that partition fall into the fruit box through the hollow area.

[0019] With the above structure, the vertical conveying component does not place fruits and vegetables at the center of the rotating disc, but rather offset them onto its upper plate. The fruits and vegetables rotate with the upper plate within its designated sections, and finally fall when aligned with the open area of ​​the lower plate, achieving stacking in the rotational direction. A rotary drive mechanism is connected to both the upper and lower plates, providing differential rotation, with the upper plate rotating at a higher speed than the lower plate. Specifically, the upper plate drives the fruits and vegetables to rotate relative to the lower plate, and whenever one section rotates to align with the open area, the fruits and vegetables in that section fall into the fruit box through the open area.

[0020] Optionally, the frame includes a mounting frame and a support structure. The vertical conveying assembly is connected to the mounting frame. The mounting frame is located above and connected to the support structure. The projected outline of the frame on the horizontal plane includes a first edge and a second edge that are perpendicular to each other and connected. The support structure is disposed on the first edge and the second edge. The area at the bottom of the frame where the support structure is not disposed allows the fruit box to pass through and move to the bottom of the boxing assembly.

[0021] The aforementioned structure, with support structures along the first and second perpendicular edges, creates an L-shaped open bottom structure. This completely opens up the area at the bottom of the frame where no support structure is present, providing a passage for the fruit boxes to enter and exit. Operators can easily push or pull the fruit boxes in or out from at least two different directions, greatly improving the efficiency of changing fruit boxes.

[0022] In another aspect, embodiments of this application provide a fruit and vegetable sorting device, including a fruit and vegetable packing machine as described in any of the above claims.

[0023] The embodiments of this application achieve the following technical effects: By controlling the falling speed of fruits and vegetables through a vertical conveying component, the embodiments of this application avoid excessive impact force caused by gravity acceleration. Simultaneously, the rotating stacking method of the packing component ensures that fruits and vegetables are placed stably and orderly, rather than piled up haphazardly, thereby achieving high efficiency and low loss in the automated packing process and effectively protecting the integrity and quality of the fruits and vegetables.

[0027] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or one or more intermediate elements can exist between them. The terms "upper," "lower," "left," "right," "upper end," "lower end," "top," and "bottom," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0029] In related technologies, the existing conveying methods of fruit and vegetable packing machines, whether simple free fall or rough mechanical conveying, are difficult to precisely control the vertical movement speed and posture of fruits and vegetables. This makes it easy for fruits and vegetables to be damaged during the fall or transfer process due to excessive impact, collisions, or hard contact with the receiving equipment structure.

[0030] Please refer to the following: Figure 1 and Figure 2 To address the aforementioned technical problems, this application provides a fruit and vegetable packing machine 100, which includes a frame 10, a packing assembly 20, and a vertical conveying assembly 30. The packing assembly 20 has a fruit box at its bottom for stacking fruits and vegetables in a rotating direction. The vertical conveying assembly 30 is connected to both the frame 10 and the packing assembly 20, and is located above the packing assembly 20. The vertical conveying assembly 30 conveys fruits and vegetables to the packing assembly 20 at a preset speed.

[0031] The working principle of the fruit and vegetable packing machine 100 in this embodiment is as follows: The vertical conveying component 30 conveys fruits and vegetables located at a high position downwards at a preset speed, and then delivers them to the packing component 20 at the bottom for receipt. The packing component 20, through its rotational motion, orderly stacks the received fruits and vegetables into the fruit box in a layered manner.

[0032] Understandably, in this embodiment, the vertical conveying component 30 controls the falling speed of fruits and vegetables, avoiding excessive impact force caused by gravity acceleration. Simultaneously, the rotating stacking method of the packing component 20 ensures that fruits and vegetables are placed stably and orderly, rather than piled up haphazardly, thereby achieving high efficiency and low loss in the automated packing process and effectively protecting the integrity and quality of the fruits and vegetables.

[0033] The rotation direction mentioned in this embodiment is the same as the rotation direction of the rotating disk 21, and can be set to clockwise or counterclockwise.

[0034] Please refer to 3 and 4 together. Figure 4In some embodiments, the vertical conveying assembly 30 includes a first housing 31, a vertical conveyor belt 32, and a plurality of support units 33. The first housing 31 has a receiving chamber 311, in which the vertical conveyor belt 32 is received, and the conveying direction of the vertical conveyor belt 32 is vertically downward. The plurality of support units 33 are spaced apart along the length of the vertical conveyor belt 32 and connected to the belt surface of the vertical conveyor belt 32, and the support units 33 are used to support a preset number of fruits and vegetables.

[0035] Understandably, this embodiment employs a vertical conveyor belt 32 operating within a closed first housing 31, with multiple independent support units 33 spaced apart on the belt surface. Each support unit 33 is configured to carry a preset quantity (e.g., one to several) of fruits and vegetables. As the vertical conveyor belt 32 circulates, the support units 33 transport the fruits and vegetables in batches and quantities smoothly from a height to the bottom, effectively preventing the fruits and vegetables from being squeezed and collided with each other during the fall. Simultaneously, the spaced support units 33 ensure that the feeding of materials to the packaging assembly 20 is rhythmic and intermittent, avoiding instantaneous accumulation of materials.

[0036] In some embodiments, each support unit 33 includes a plurality of support fingers 331, which are spaced apart in the width direction of the vertical conveyor belt 32 and connected to the belt surface of the vertical conveyor belt 32.

[0037] Understandably, each support unit 33 comprises multiple support fingers 331 spaced apart along the width of the conveyor belt, rather than a single flat plate. These support fingers 331 collectively form a comb-like support surface to stably support the fruits and vegetables. The multi-point support finger 331 structure better adapts to the curved surface of round fruits and vegetables, preventing them from rolling. Compared to a solid flat plate, the finger structure is lighter, saves materials, and is less prone to water accumulation during washing and other processes, making the structure lighter while ensuring support stability.

[0038] In other embodiments, the support unit 33 may also be a flat plate or an arc-shaped plate, etc.

[0039] In some embodiments, one end of the support finger 331 is connected to the surface of the vertical conveyor belt 32, and the other end of the support finger 331 is bent and extended in the opposite direction to the direction of movement of the vertical conveyor belt 32.

[0040] Understandably, one end of the support finger 331 is connected to the conveyor belt, while the other end extends and bends in the opposite direction of the conveyor belt's movement. Specifically, the other end of the support finger 331 can laterally restrain the fruits and vegetables, so that when the conveyor belt moves downward, it can firmly hold the fruits and vegetables, prevent them from slipping, and avoid collision with the inner wall of the first housing 31.

[0041] Please review Figure 3In some embodiments, the bottom of the first housing 31 is provided with a lateral opening 312 and a guide ramp 313, the guide ramp 313 faces the lateral opening 312 and is inclined downward, and the lateral opening 312 is at a preset height from the packing assembly 20.

[0042] The supporting unit 33 can place the fruits and vegetables on the guide ramp 313 and abut against the fruits and vegetables when it moves to the bottom of the first housing 31, so that the fruits and vegetables continue to move on the guide ramp 313 at a preset speed, and release the fruits and vegetables when it rises and resets, so that the fruits and vegetables fall into the packing assembly 20 through the side opening 312.

[0043] Understandably, at the bottom of the first housing 31, where the vertical conveyor belt 32 turns, a side opening 312 and an inclined guide ramp 313 are provided. When the supporting unit 33 lifts the fruits and vegetables and moves them to this area, it does not allow the fruits and vegetables to fall directly. Instead, it first places the fruits and vegetables smoothly on the guide ramp 313 and continues to block the fruits and vegetables from moving a short distance along the ramp at the same linear speed as the vertical conveyor belt 32. Subsequently, when the supporting unit 33 begins to reset upward, it releases the fruits and vegetables, allowing them to slide out from the side opening 312 along the ramp and fall into the packaging assembly 20. This effectively prevents the fruits and vegetables from rolling freely on the guide ramp 313, reduces the impact force after the fruits and vegetables slide out from the side opening 312, and thus reduces the damage rate of the fruits and vegetables.

[0044] In some embodiments, the vertical conveying assembly 30 further includes a buffer brush disposed in the lateral opening 312, the buffer brush being used to reduce the speed at which fruits and vegetables leave the lateral opening 312.

[0045] Understandably, a row of soft, cushioning brushes is installed along the path of the fruits and vegetables as they slide out of the side opening 312. The fruits and vegetables pass through these brushes as they leave the guide ramp 313. The flexible bristles of the cushioning brushes provide slight resistance to the sliding fruits and vegetables, effectively reducing their speed as they finally fall into the packing assembly 20, further reducing the impact force after they slide out of the side opening 312.

[0046] In some embodiments, the vertical conveying assembly 30 further includes a roller brush 34 and a roller brush drive 35. The roller brush 34 is disposed in the lateral opening 312. The roller brush drive 35 is mounted on the first housing 31 and connected to the roller brush 34, and the roller brush drive 35 is used to drive the roller brush 34 to rotate. The rotation direction of the roller brush 34 is the same as the running direction of the vertical conveyor belt 32.

[0047] Understandably, in this embodiment, the passive buffer brush described in the previous embodiment is replaced with an actively rotating roller brush 34 driven by the roller brush drive 35. The rotation direction of the roller brush 34 is the same as the downward running direction of the vertical conveyor belt 32. When fruits and vegetables move close to the side opening 312, they are blocked by the bristles of the roller brush 34, and then pushed until they are pushed out of the side opening 312, effectively reducing the speed at which the fruits and vegetables finally fall into the packing assembly 20, and further reducing the impact force after the fruits and vegetables slide out of the side opening 312.

[0048] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the fruit and vegetable packing machine 100 further includes a feeding conveyor belt 60, which is connected to the vertical packing assembly 30. Exemplarily, the output end of the feeding conveyor belt 60 is connected to a first housing 31, which has a feeding opening aligned with the feeding conveyor belt 60. The feeding conveyor belt 60 is used to convey fruits and vegetables to the vertical packing assembly 30 through the feeding opening, and then the fruits and vegetables are transported downwards by the supporting unit 33 of the vertical packing assembly 30. Also exemplaryly, the feeding conveyor belt 60 extends obliquely upwards to the vertical packing assembly 30, and the belt surface of the feeding conveyor belt 60 is wavy to prevent the fruits and vegetables from rolling back during transport.

[0049] Please refer to the following: Figures 5 to 7 In some embodiments, the packing assembly 20 includes a rotating disk 21 and a rotation drive mechanism 22. The rotating disk 21 is used to hold fruits and vegetables. The vertical conveying assembly 30 is offset relative to the axis of the rotating disk 21. The rotating disk 21 includes an upper disk 211 and a lower disk 212 arranged coaxially. The upper disk 211 has at least two partitions 2111 around the axis, and the lower disk 212 has a hollow area 2121 offset relative to the axis. The area directly below the lower disk 212 is used to place fruit boxes.

[0050] Understandably, the vertical conveying component 30 does not place the fruits and vegetables into the center of the rotating disk 21, but rather offset them onto its upper disk 211. The fruits and vegetables rotate within the partitions 2111 of the upper disk 211, and finally fall when aligned with the hollowed-out area 2121 of the lower disk 212, achieving stacking in the rotational direction. The rotary drive mechanism 22 is connected to both the upper disk 211 and the lower disk 212, and is used to differentially drive their rotation, with the upper disk 211 rotating at a higher speed than the lower disk 212. Specifically, the upper disk 211 can drive the fruits and vegetables to rotate relative to the lower disk 212. Whenever one of the partitions 2111 rotates to align with the hollowed-out area 2121, the fruits and vegetables in partition 2111 fall into the fruit box through the hollowed-out area 2121.

[0051] To put it more simply, the vertical conveyor assembly 30 ensures that fruits and vegetables arrive smoothly in a low-speed, quantitative, and batch manner, while the differentially rotating turntable 21 is responsible for efficiently, orderly, and collision-free distribution of these arriving fruits and vegetables to different positions in the fruit box. The coordinated work of the two reduces the stacking and collision of fruits and vegetables during the packing process.

[0052] Please refer to the following: Figure 1 and Figure 8 In some embodiments, the frame 10 includes a mounting frame 11 and a support structure 12. The vertical conveying assembly 30 is connected to the mounting frame 11. The mounting frame 11 is located above and connected to the support structure 12. The projected outline of the frame 10 on the horizontal plane includes a first edge 10a and a second edge 10b that are perpendicular to each other and connected. The support structure 12 is disposed on the first edge 10a and the second edge 10b. The area at the bottom of the frame 10 where the support structure 12 is not disposed allows the fruit box to pass through and move under the boxing assembly 20.

[0053] Understandably, the support structure 12 of the frame 10 is not a traditional four-corner design, but rather the support structure 12 is only provided along the mutually perpendicular first edge 10a and second edge 10b, forming an L-shaped open bottom structure. This makes the area at the bottom of the frame 10 without the support structure 12 completely open, providing a passage for the fruit boxes to enter and exit. Operators can easily push or pull the fruit boxes in from at least two different directions, greatly improving the efficiency of changing fruit boxes.

[0054] In some embodiments, the support structure 12 includes support columns 122 and support beams 121. The L-shaped structure formed by the first edge 10a and the second edge 10b includes a first end, a second end, and an included angle. Each of the first end, the second end, and the included angle is provided with a corresponding support column 122. A corresponding support beam 121 is provided from the first end to the included angle and from the second end to the included angle. The support columns 122 are connected to the mounting frame 11, and the support beams 121 are connected to the support columns 122 at both ends.

[0055] In some embodiments, the frame 10 further includes an auxiliary support foot 13, the auxiliary support foot 13 having an L-shaped profile on the horizontal projection plane, the auxiliary support foot 13 including a connecting portion and a supporting portion that are perpendicularly connected to each other on the horizontal projection plane, the connecting portion being detachably connected to one of the supporting beams 121, and the supporting portion being parallel to the other supporting beam 121 and abutting against the ground.

[0056] In some embodiments, the number of partitions 2111 in the upper tray 211, the number of open areas 2121 in the lower tray 212, and their positions can be set according to the required packing efficiency, and are not limited here. For example, the upper tray 211 has 5 partitions 2111, and each partition 2111 can hold one, two, or more fruits and vegetables. The lower tray 212 has 2 open areas 2121, which are located on the same diameter of the lower tray 212 and are arranged opposite to each other.

[0057] Please refer to the following: Figure 6 , Figure 7 , Figure 9 and Figure 10 In some embodiments, the upper plate 211 includes a first spindle 2112 located at its center, and the first spindle 2112 has a first central hole 21121 along its axis. The lower plate 212 includes a second spindle 2122 located at its center, the second spindle 2122 passing through the first central hole 21121, and the second spindle 2122 is rotatable relative to the first spindle 2112. A rotary drive mechanism 22 is connected to the first spindle 2112 and the second spindle 2122 respectively, and is used to differentially drive the first spindle 2112 and the second spindle 2122 to rotate, so that the upper plate 211 and the lower plate 212 rotate respectively.

[0058] Understandably, the upper plate 211 is fixed to a hollow first spindle 2112, while the lower plate 212 is fixed to a second spindle 2122 that passes through the hole of the first spindle 2112. The rotary drive mechanism 22 is connected to these two independent spindles respectively, and by controlling the rotational speeds of the first spindle 2112 and the second spindle 2122 respectively, the coaxial but different speed rotational motions of the upper plate 211 and the lower plate 212 are realized.

[0059] To be more easily understood, the first spindle 2112 is fitted onto the second spindle 2122, which has a compact structure, high space utilization and stable transmission, and ensures that the upper plate 211 and the lower plate 212 maintain precise coaxiality during rotation, thereby improving the stability of the rotating plate 21.

[0060] Please refer to the following: Figure 9 and Figure 10 In some embodiments, the second spindle 2122 passes through the first spindle hole 21121 and extends outward, and the rotary drive mechanism 22 includes a rotary drive motor 221, a drive shaft 222, a first gear set 223, and a second gear set 224.

[0061] A rotary drive motor 221 is connected to and drives the second spindle 2122 to rotate. The drive shaft 222 is arranged parallel to the second spindle 2122. A first gear set 223 includes a first gear 2231 and a second gear 2232 that mesh with each other. The first gear 2231 is fitted onto the second spindle 2122, and the second gear 2232 is fitted onto the drive shaft 222. A second gear set 224 includes a third gear 2241 and a fourth gear 2242 that mesh with each other. The third gear 2241 is fitted onto the first spindle 2112, and the fourth gear 2242 is fitted onto the drive shaft 222.

[0062] The second spindle 2122 drives the drive shaft 222 to rotate via the first gear set 223, and the drive shaft 222 drives the first spindle 2112 to rotate via the second gear set 224.

[0063] Understandably, the rotary drive motor 221 directly drives the protruding second spindle 2122. Simultaneously, the first gear 2231 fixed on the second spindle 2122 meshes with the second gear 2232 on the drive shaft 222, transmitting power to the drive shaft 222. Next, the fourth gear 2242 on the drive shaft 222 meshes with the third gear 2241 mounted on the first spindle 2112, returning power to the first spindle 2112. By setting the gear ratio between the first gear set 223 and the second gear set 224, the power transmitted from the second spindle 2122 to the first spindle 2112 undergoes a change in speed and transmission ratio after passing through the drive shaft 222. This allows a single rotary drive motor 221 to drive the upper plate 211 and the lower plate 212, enabling them to rotate at different speeds.

[0064] To be more easily understood, differential transmission is achieved using only a single rotary drive motor 221, which effectively simplifies the rotary drive mechanism 22 and reduces equipment cost and control complexity.

[0065] In some embodiments, the upper plate 211 further includes a plurality of baffles 2113 and a buffer pad 2114. The plurality of baffles 2113 are spaced apart around an axis, and two adjacent baffles 2113 form a single partition 2111. Each partition 2111 is covered with a corresponding buffer pad 2114, and the buffer pad 2114 is connected to the baffle 2113 that is relatively forward in the rotational direction in the corresponding partition 2111.

[0066] When partition 2111 rotates to align with the hollowed-out area 2121, the cushioning pad 2114 hangs down through the hollowed-out area 2121 so that the fruits and vegetables in partition 2111 fall into the fruit box. When partition 2111 rotates to be misaligned with the hollowed-out area 2121, the baffle 2113 connected to the cushioning pad 2114 pulls the cushioning pad 2114 up from the hollowed-out area 2121 so that the cushioning pad 2114 is re-laid on partition 2111.

[0067] Understandably, the bottom of each section 2111 of the upper plate 211 is not a rigid plane, but rather covered with a flexible cushioning pad 2114. One end of this cushioning pad 2114 is connected to the baffle 2113 in front of the section 2111. During normal rotation, the cushioning pad 2114 is supported by the solid part of the lower plate 212, forming a flat bearing surface. When the section 2111 rotates to align with the hollow area 2121 of the lower plate 212, the cushioning pad 2114 loses its support and droops downwards due to its own weight and the weight of the fruits and vegetables, allowing the fruits and vegetables in the section 2111 to slide down smoothly. After the section 2111 rotates past the hollow area 2121, the baffle 2113 connected to it will smoothly pull the drooping cushioning pad 2114 from the edge of the hollow area 2121 as the upper plate 211 rotates, making it flat again and ready to receive the next batch of fruits and vegetables.

[0068] To be more easily understood, this embodiment of the application provides a corresponding buffer pad 2114 in each partition 2111, so that fruits and vegetables can be cushioned when they fall into the partition 2111, reducing collisions. Furthermore, during the alignment of the buffer pad 2114 in the partition 2111 with the perforated area 2121, the fruits and vegetables do not fall directly downwards through the perforated area 2121, but rather through a gentle, gradual release process. Before the buffer pad 2114 is fully aligned with the perforated area 2121, it briefly supports the fruits and vegetables, and then gradually lowers vertically as the opening formed by the alignment increases, thus releasing the fruits and vegetables and preventing them from falling directly vertically into the fruit box and causing damage.

[0069] In some embodiments, the baffle 2113 is partially covered by the structure of the buffer pad 2114 to prevent the fruits and vegetables in the partition 2111 from colliding and being damaged by the baffle 2113.

[0070] In some embodiments, the upper plate 211 further includes a protective cover 2115, which houses the first spindle 2112. The protective cover 2115 is provided with a plurality of bar clearance holes 21151 spaced apart around the axis. The bar clearance holes 21151 extend in the height direction. One end of each bar 2113 passes through the corresponding bar clearance hole 21151 and is hinged to the first spindle 2112. The hinge axis between the bar 2113 and the first spindle 2112 is perpendicular to the first spindle 2112.

[0071] When some fruits and vegetables in the fruit box emerge from the hollow area 2121, the buffer pad 2114 in the hollow area 2121 can be lifted by the emerging fruits and vegetables, so that the baffle 2113 rotates upward relative to the first spindle 2112 around the hinge axis.

[0072] Understandably, the fruit and vegetable separator 2113 is designed as a hinged structure that can rotate upwards around its axis and is connected to the first spindle 2112. When the fruits and vegetables in the lower fruit box pile up too high, causing them to overflow the open area 2121, these overflowing fruits and vegetables will push up the falling buffer pad 2114. Since the buffer pad 2114 is connected to the separator 2113, the pushed-up buffer pad 2114 will cause the separator 2113 to rotate upwards around its hinge axis.

[0073] To make it easier to understand, the fruits and vegetables in the previous section 2111 fall into the fruit box through the hollow area 2121 of the lower plate 212, and the height of the piled fruits and vegetables is gradually approaching the height of the full box. At this time, if the last one or two fruits and vegetables slightly protrude from the hollow area 2121 of the lower plate 212, and the fruits and vegetables in the next section 2111 continue to be unloaded, the baffle 2113 will push against the piled fruits and vegetables in front and make them float up, so as to avoid hard interference with the piled fruits and vegetables.

[0074] In some embodiments, the rotating disk 21 further includes a detection sensor for detecting the upward movement of the baffle 2113 to determine whether the fruit box is full, and controlling the rotation drive mechanism 22 to stop the rotation of the rotating disk 21 based on the signal from the detection sensor.

[0075] In some embodiments, the lower plate 212 includes a brush structure 2123, which is disposed on the edge of the lower plate 212 and extends downward, and the brush structure 2123 is located in the centrifugal direction of the hollow area 2121.

[0076] Understandably, a downward-extending brush structure 2123 is provided on the outer edge of the lower plate 212, particularly on the centrifugal side of the hollowed-out area 2121. When the fruit and vegetable boxing machine 100 is operating, the tip of the brush will come very close to or slightly contact the inner wall of the fruit box placed below. On the one hand, the brush helps to better align the lower plate 212 with the fruit box when it is placed below; on the other hand, for fruits and vegetables falling from the hollowed-out area 2121, especially those that slightly shift outward due to inertia, the brush provides a flexible end cushion to prevent them from directly impacting the inner wall of the fruit box, further reducing the risk of damage from collisions.

[0077] Please refer to the following: Figure 2 , Figure 5 , Figure 6 , Figure 9 and Figure 10 In some embodiments, the rotating disk 21 includes a guide plate 213 located below the lower disk 212. Each hollow area 2121 has a corresponding guide plate 213 hinged to its relatively forward edge in the rotation direction. The guide plate 213 can rotate relative to the lower disk 212. The guide plate 213 is used to tilt and guide the fruits and vegetables falling from the hollow area 2121 to the fruit box.

[0078] The bottom surface of the guide plate 213 can be abutted by the fruits and vegetables in the fruit box, and the included angle between the guide plate 213 and the lower plate 212 decreases as the height of the fruits and vegetables in the fruit box increases.

[0079] Understandably, a freely rotatable guide plate 213 is hinged to the front edge of the hollow area 2121 of the lower plate 212. Under normal circumstances, the guide plate 213 tilts due to its own weight or a preset angle. Fruits and vegetables falling from the hollow area 2121 will first land on the guide plate 213 and then be gently guided into the center of the fruit box. As the fruits and vegetables continue to accumulate in the fruit box, their height will gradually increase and rise to contact the bottom surface of the guide plate 213, thereby lifting it upwards and reducing the angle between it and the lower plate 212.

[0080] To put it more easily, the inclined guide plate 213 provides a secondary deceleration and buffer for the falling fruits and vegetables, allowing them to enter the fruit box more smoothly.

[0081] For example, the guide plate 213 has a certain elastic deformation or is covered with flexible leather to improve the cushioning capacity for fruits and vegetables.

[0082] Please review Figure 2 In some embodiments, the top surface of the guide plate 213 is provided with a plurality of mutually spaced protrusions 2131, which extend in the width direction of the guide plate 213.

[0083] Understandably, multiple spaced-apart raised structures 2131 are provided along the width direction on the top surface of the guide plate 213, i.e., the side that contacts the fruits and vegetables. By adding the raised structures 2131, the cushioning performance of the guide plate 213 is further enhanced. When the fruits and vegetables fall onto the guide plate 213, they roll on the guide plate 213, and the rolling speed is reduced when they come into contact with the raised structures 2131, so as to reduce the impact on other fruits and vegetables in the fruit box.

[0084] In some embodiments, the lower plate 212 further includes a disc 2124 limiting sidewall 2125, a hollow area 2121 is provided on the disc 2124, the limiting sidewall 2125 is located at the edge of the disc 2124 and connected to the disc 2124, the limiting sidewall 2125 and the disc 2124 together enclose a receiving space, and the upper plate 211 and fruits and vegetables are received in the receiving space.

[0085] Understandably, the lower plate 212 not only includes a bottom surface of a disc 2124 with a hollowed-out area 2121, but also has an upwardly extending limiting sidewall 2125 integrally or connected to its outer edge. This sidewall, together with the bottom surface of the disc 2124, forms a receiving space that encompasses the entire upper plate 211 and the fruits and vegetables moving on it. The limiting sidewall 2125 effectively prevents fruits and vegetables from being thrown out of the rotating disc 21 due to centrifugal force during high-speed rotation, ensuring that all fruits and vegetables are guided to the preset hollowed-out falling area, avoiding material loss and pollution to the surrounding environment.

[0086] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the fruit and vegetable packing machine 100 also includes a detection mechanism 40, a lifting drive mechanism 50, and a controller.

[0087] The detection mechanism 40 is connected to the boxing assembly 20 and is used to detect the filling status of the fruit box. The lifting drive mechanism 50 is connected to both the frame 10 and the vertical conveying assembly 30 and is used to drive the vertical conveying assembly 30 to move up and down relative to the frame 10. The controller is electrically connected to both the detection mechanism 40 and the lifting drive mechanism 50 and is used to control the lifting drive mechanism 50 to drive the vertical conveying assembly 30 and the boxing assembly 20 to rise relative to the frame 10 when the detection mechanism 40 confirms that the fruit box is full, so that the boxing assembly 20 is detached from the fruit box.

[0088] Understandably, firstly, the detection mechanism 40 monitors the filling status of the fruit box in real time; once it detects that the fruit box is full, it immediately sends a signal to the controller; after receiving the signal, the controller will control the lifting drive mechanism 50 to drive the vertical conveying component 30 to lift the boxing component 20 vertically upward, so that it is completely separated from and higher than the full fruit box below.

[0089] To be more easily understood, this embodiment of the application uses a detection mechanism 40 to automatically determine whether the fruit box is full, reducing manual operation. Once full, the controller controls the lifting drive mechanism 50 to lift the entire boxing assembly 20 upwards, freeing up sufficient operating space for changing the fruit box and making the process of changing the fruit box quick and convenient.

[0090] In some embodiments, the detection mechanism 40 is located below the lower plate 212, directly below the lower plate 212, i.e. on the path where fruits and vegetables fall and accumulate, so that the accumulation height of fruits and vegetables in the fruit box can be directly and accurately monitored.

[0091] Please refer to the following: Figure 5 , Figure 6 , Figure 9 and Figure 10In some embodiments, the detection mechanism 40 includes a movable plate 41 and a sensor. The movable plate 41 is located below and hinged to the lower plate 212, and the movable plate 41 can be flipped upward by being pressed against by fruits and vegetables in the fruit box.

[0092] The sensor is electrically connected to the controller and is used to send a full box signal to the controller when the movable plate 41 is flipped upward to a preset angle, so that the controller controls the lifting drive mechanism 50 to drive the vertical conveying assembly 30 and the packing assembly 20 to rise relative to the frame 10 according to the full box signal.

[0093] Understandably, one or more freely rotating movable plates 41 are hinged below the lower plate 212. Initially, the movable plates 41 hang naturally. As the fruit and vegetables inside the box increase in number and height, they eventually push the movable plate 41 upwards, causing it to rotate upwards around the hinge point. When the rotation angle of the movable plate 41 reaches a preset angle, it triggers the associated sensor, which then sends a full box signal to the controller.

[0094] Please see Figure 11 In some embodiments, the sensor is located below the lower plate 212. The sensor is a micro switch 421. When the movable plate 41 is pushed up by the fruits and vegetables in the fruit box and flips upward at a preset angle, it pushes against the micro switch 421, so that the sensor is triggered and sends a full box signal to the controller.

[0095] Understandably, a micro switch 421 is used as a sensor. When the movable plate 41 is lifted by fruits and vegetables and flipped to a preset angle, it will directly make physical contact with and press the contacts of the micro switch 421, thereby closing the circuit, triggering and sending a full box signal to the controller.

[0096] Please refer to the following: Figure 9 , Figure 10 , Figures 12 to 14 In some embodiments, the sensor is disposed above the second spindle 2122. The sensor is a non-contact sensor 422. The second spindle 2122 is provided with a second shaft hole 21221. There are two movable plates 41, and the two movable plates 41 are arranged opposite each other in the same diameter direction of the lower plate 212. Each movable plate 41 is provided with a ring 411.

[0097] The detection mechanism 40 also includes a linkage rod 43 and a push rod 44. The linkage rod 43 passes sequentially through the annulus 411 of the two movable plates 41 and is located directly below the second axial hole 21221. The push rod 44 passes through the second axial hole 21221, with one end of the push rod 44 abutting against the linkage rod 43 and the other end extending out of the second spindle 2122. In the initial state, the push rod 44 is at a preset distance from the sensor in the height direction. When the push rod 44 rises beyond the preset distance, it can be detected by the sensor, causing the sensor to trigger and send a full box signal to the controller.

[0098] When the two movable plates 41 are flipped upward to a preset angle, they can lift the linkage rod 43 by a preset distance through the ring 411, so that the top rod 44 can be detected by the sensor.

[0099] Understandably, when the two movable plates 41 at the bottom are lifted by fruits and vegetables, a linkage rod 43 passing through their ring 411 will be raised simultaneously. The linkage rod 43 then pushes a top rod 44 passing through the second spindle 2122 of the lower plate 212; the top of the top rod 44 moves upward and eventually enters the sensing range of the non-contact sensor 422 located above the second spindle 2122, thereby triggering the sensor to send a full box signal. The arrangement of the double movable plates 41 and the linkage rod 43 makes the detection action smoother and avoids misjudgments caused by fruit and vegetable offset that may occur in single-point detection, making it more reliable than the detection method of the micro switch 421.

[0100] For example, the non-contact sensor 422 may be a photoelectric sensor or the like.

[0101] Please see Figure 1 and Figure 15 In some embodiments, the lifting drive mechanism 50 includes a lifting drive unit 51 and a guide unit 52. The lifting drive unit 51 is connected to the vertical conveying assembly 30, the frame 10, and the controller, respectively. The lifting drive unit 51 is controlled by the controller and is used to drive the vertical conveying assembly 30 to move up and down relative to the frame 10. The guide unit 52 is connected to the vertical conveying assembly 30 and the frame 10, respectively, and is used to provide guidance when the vertical conveying assembly 30 moves up and down.

[0102] Understandably, in addition to the lifting drive unit 51 that drives the vertical conveying component 30 and the packing component 20 to lift and lower, the lifting drive mechanism 50 also adopts a guide unit 52 to ensure that the large and heavy vertical conveying and packing components can maintain a strictly vertical posture during the lifting process, avoiding shaking, tilting or jamming, and ensuring the smoothness and safety of equipment operation.

[0103] In some embodiments, the lifting drive unit 51 includes a rack 511, a lifting drive gear 512, and a lifting drive motor 513. The rack 511 is connected to the vertical conveying assembly 30 and extends in the height direction of the vertical conveying assembly 30. The lifting drive gear 512 is mounted on the frame 10 and meshes with the rack 511. The lifting drive motor 513 is connected to both the lifting drive gear 512 and a controller. The lifting drive motor 513 is controlled by the controller to drive the lifting drive gear 512 to rotate, thereby causing the vertical conveying assembly 30 to move vertically through the meshing transmission between the lifting drive gear 512 and the rack 511.

[0104] In other embodiments, the lifting drive unit 51 may also use a lead screw slider mechanism, linear cylinder drive or electric telescopic rod to achieve lifting, and there is no limitation here.

[0105] Understandably, a vertical rack 511 is fixed to the vertical conveying assembly 30 that needs to be raised and lowered, and a lifting drive gear 512 that meshes with the rack 511 is installed on the frame 10. The lifting drive gear 512 is driven to rotate by a lifting drive motor 513 controlled by a controller. The forward and reverse rotation of the lifting drive gear 512 can drive the rack 511 and the vertical conveying assembly 30 connected to it to rise and fall, thereby causing the packing assembly 20 to rise and fall.

[0106] Please review Figure 2 In some embodiments, the vertical conveying assembly 30 includes a first housing 31 for housing other components of the vertical conveying assembly 30. A rack 511 is mounted on the first housing 31. The packing assembly 20 includes a second housing 23 for housing a first spindle 2112 and a second spindle 2122 and for driving both to rise and fall. The first housing 31 is connected to the second housing 23, so that when the first housing 31 moves up and down, the second housing 23 drives the entire packing assembly 20 to rise and fall.

[0107] Optionally, the number of guide units 52 can be set according to actual needs, and there is no limit here.

[0108] In some embodiments, the guide unit 52 includes a guide post 521 and two guide wheel sets 522. The guide post 521 is connected to the vertical conveying assembly 30. The guide wheel sets 522 are rotatably mounted on the frame 10. Each guide wheel set 522 includes a plurality of guide wheels 5221 aligned in the height direction. The two guide wheel sets 522 are spaced apart, and the guide post 521 is located between the two guide wheel sets 522 and abuts against the guide wheels 5221 of the two guide wheel sets 522 respectively.

[0109] Understandably, guide columns 521 are installed on the vertical conveying assembly 30 for lifting, while two sets of guide wheel sets 522 are provided on the fixed frame 10 to hold the guide columns 521 in the middle. When the working unit lifts or lowers, the guide columns 521 slide up and down between these two sets of guide wheels 5221. In this embodiment, the sliding friction between the guide wheels 5221 and the guide columns 521 greatly reduces the resistance during the lifting process, making the lifting smoother.

[0110] In other embodiments, the guide unit 52 may also employ a guide rail slider mechanism or the like for guidance, and this is not a limitation.

[0111] In some embodiments, the controller may be a commonly used programmable logic controller (PLC) or a microcontroller with a preset program. The controller is at least able to acquire the sensor signal and send instructions to the lifting drive motor 513 to control the lifting drive mechanism 50 to drive the vertical conveying component 30 to lift according to the sensor signal.

[0112] Please refer to the following: Figure 1 and Figure 2 On the other hand, embodiments of this application provide a fruit and vegetable sorting device, including the fruit and vegetable packing machine 100 as described in the above embodiments.

[0113] It is understood that the fruit and vegetable packing machine 100 in the above embodiments is applied to the fruit and vegetable sorting equipment in this application embodiment, so that the fruit and vegetable sorting equipment can ensure that the fruits and vegetables are stably transported to the packing component 20 when the packing process is carried out, so as to stack and pack them through the packing component 20, thereby ensuring the quality of the fruits and vegetables.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; under the concept of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
