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] In the fruit and vegetable processing and packaging sector, automated packing is a key step in improving production efficiency and reducing labor costs.

[0003] Current fruit and vegetable packing operations typically involve dropping the pallets directly from the pallet conveyor belt or pushing them into the packaging boxes. This method, especially when placing the bottom pallets, involves a significant vertical drop, making the fruits and vegetables inside highly susceptible to damage from impact. Utility Model Content

[0004] 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 during the pallet stacking process, there is a large vertical drop height, which makes the fruits and vegetables in the pallet easily damaged due to impact.

[0005] This application provides a fruit and vegetable packing machine, including:

[0006] The support assembly includes two spaced-apart support units;

[0007] A support rope is connected to two of the support units respectively, and the support rope forms a support portion between the two support units. The support rope includes a first end and a second end opposite to each other.

[0008] A support platform, located above the support section, is used to support trays containing fruits and vegetables that are sequentially input. The support platform can be opened intermittently so that the trays can be stacked on the support section.

[0009] A drive assembly drives the first and second ends of the support rope to lower the support portion as the number of pallets on the support portion increases, so that the topmost pallet is kept at a preset height, and pulls the support rope away from under the pallets when the number of pallets on the support portion reaches a preset number, so as to unload the stacked pallets.

[0010] The aforementioned structure dynamically adjusts the height of the support section, ensuring that the falling height of each subsequent pallet is small and constant, significantly reducing impact and effectively protecting the quality and integrity of fruits and vegetables. Furthermore, this embodiment automates pallet stacking and unloading, replacing traditional manual or extensive mechanical operations, significantly improving production efficiency and automation levels in the packing process, and reducing labor costs and product loss rates.

[0011] Optionally, the support platform includes a pull-out plate unit for supporting the sequentially input pallet, the pull-out plate unit comprising:

[0012] A blocking element is positioned directly opposite the input direction of the tray;

[0013] A pull plate is located between the support and the blocking member in the height direction. The pull plate can move relative to the blocking member to directly below the blocking member. The initial position of the pull plate is directly above the support.

[0014] A first drive module, connected to the pull plate, is used to drive the pull plate to move intermittently to directly below the blocking member, so that the tray is stacked on the support.

[0015] Through the aforementioned structure, the cooperation of the pull plate and the blocking components ensures that each pallet is in the correct predetermined position before falling, guaranteeing the neatness and stability of subsequent stacking. The intermittent driving method enables precise control of the packing rhythm, allowing it to perfectly match the speed of the front pallet conveyor belt, thereby ensuring the continuity and smoothness of the entire packing process.

[0016] Optionally, the support platform further includes:

[0017] The split panel is located directly above the support and below the pull plate in the height direction. The split panel can be flipped downwards to open or reset to close relative to the support.

[0018] The second drive module is connected to the split panel and is used to drive the split panel to open or close.

[0019] The first tray supported by the pull plate falls onto the split panel after the pull plate is opened, and then falls onto the support part after the split panel is opened. The split panel remains open after the first tray falls onto the support part, and returns to the closed state after all the trays stacked on the support part are completely unloaded.

[0020] With the above structure, the originally relatively long drop process of the first tray is broken down into two shorter drops, reducing the initial impact and minimizing the risk of damage to fruits and vegetables.

[0021] Optionally, the split panel includes two panel units, which are arranged sequentially along the length of the support portion. The second drive module is connected to each panel unit respectively, and the second drive module is used to drive the two panel units to flip downwards to open or flip upwards to reset and close.

[0022] The panel unit is provided with a clearance groove, and each clearance groove is aligned with a corresponding support rope. When the panel unit is flipped downward, each clearance groove avoids the corresponding support rope.

[0023] With the above structure, the split panel is configured as two panel units arranged along the length of the support section, and they are driven to flip synchronously by the second drive module. Each panel unit has a clearance groove corresponding to the position of the support rope below. When the two panel units flip downwards and open, the clearance groove can bypass the support rope, so that the flipping action of the panel will not interfere with the support rope.

[0024] Optionally, the driving component includes:

[0025] A rope winding mechanism, connected to the first end of the supporting rope, is used to wind up and unwind the supporting rope;

[0026] A rope-grabbing mechanism is connected to the second end of the supporting rope. The rope-grabbing mechanism is movable relative to the rope-winding mechanism to move closer to or further away from the rope-winding mechanism. The rope-grabbing mechanism is used to grab or release the second end.

[0027] When the number of pallets on the support increases, the rope-grabbing mechanism drives the second end to move and approach the rope-winding mechanism, so as to lower the support and keep the uppermost pallet at a preset height.

[0028] When the number of pallets on the support reaches the preset number, the rope-grabbing mechanism releases the second end, and the rope-winding mechanism cooperates with the rope-grabbing mechanism to wind up the support rope and pull the support rope away from under the pallets to unload the stacked pallets.

[0029] After the stacked pallets are completely unloaded, the rope gripping mechanism can move close to the rope winding mechanism and re-grip the second end, and after gripping the second end, move away from the rope winding mechanism back to the initial position. The rope winding mechanism can cooperate with the rope gripping mechanism to retract the supporting rope.

[0030] With the above structure, during the descent phase, the fruit and vegetable packing machine can achieve smooth and precise height changes between the support section and the pallet through the translational control of the rope-grabbing mechanism. During the unloading phase, the fruit and vegetable packing machine achieves a fast and thorough rope-pulling action by releasing one end and quickly winding it up from the other end, thus improving unloading efficiency.

[0031] Optionally, the rope winding mechanism includes:

[0032] A reel is connected to the first end of the supporting rope;

[0033] The rotating shaft is fixedly connected coaxially to the reel.

[0034] The third drive module is connected to the rotating shaft and is used to drive the rotating shaft to rotate, so as to drive the reel to wind up or unwind the supporting rope.

[0035] Through the aforementioned structure, the third drive module drives the rotating shaft to rotate, which in turn drives the reel to rotate synchronously, thereby realizing the winding or unwinding function of the supporting rope. The above-mentioned configuration of the rope winding mechanism provides a stable and controllable power source for the winding and unwinding of the supporting rope, ensuring that the supporting rope can be quickly and smoothly wound and unwound during unloading and resetting processes, thus guaranteeing the efficiency and reliability of the entire equipment's cyclic operation.

[0036] Optionally, the rope-grabbing mechanism includes:

[0037] A slide rail, wherein the rope winding mechanism is located in the extending direction of the slide rail;

[0038] A finger-clamping cylinder is connected to the second end of the supporting rope and is used to grip or release the second end.

[0039] A connecting arm is connected to the finger clamp cylinder;

[0040] A slider is connected to both the connecting arm and the slide rail, and the slider is movable relative to the slide rail.

[0041] The fourth drive module, connected to the slider, is used to drive the slider to move relative to the slide rail, so as to drive the finger clamp cylinder to move closer to or away from the rope winding mechanism via the connecting arm.

[0042] Through the above structure, the fourth drive module drives the slider to move back and forth precisely along the slide rail, thereby driving the finger gripper cylinder to move as a whole, realizing the action of approaching or moving away from the rope winding mechanism. This ensures that the supporting rope can be stably gripped or released under various working conditions, guaranteeing the smoothness of the packing machine during the stacking and descent stage and the accuracy of the unloading and resetting stage.

[0043] Optionally, the rope-grabbing mechanism further includes:

[0044] A receiving arm is arranged parallel to the slide rail and located below the connecting arm, and the receiving arm is provided with a receiving groove with the opening facing upward;

[0045] The cable chain is housed in the receiving slot, and the air pipe of the finger clamp cylinder is housed inside the cable chain.

[0046] With the above structure, a receiving arm with an upward-opening receiving groove is arranged parallel to the slide rail, and a cable chain is laid in the receiving groove. The air pipe that supplies air to the finger gripper cylinder is housed inside the cable chain. When the finger gripper cylinder moves along the slide rail with the slider, the air pipe will bend and unfold in an orderly manner under the protection and guidance of the cable chain, and will not be dragged randomly or tangled with other parts, thus preventing it from being worn due to bending, friction or scratching during long-term reciprocating motion.

[0047] Optionally, there are multiple supporting ropes, which are arranged in parallel and spaced apart. Each support unit includes pulleys, and each pulley can roll against a corresponding supporting rope. The axes of the pulleys in each support unit are coaxial.

[0048] With the above structure, each support rope is equipped with a rolling pulley on the support units at both ends for support and guidance. To simplify the structure and ensure synchronization, all pulleys in each support unit are set coaxially, resulting in more even and stable support for the bottom of the pallet, effectively preventing the pallet from tilting or swaying during descent or support. The use of pulleys significantly reduces the friction of the support ropes during movement, allowing the drive assembly to use less force to drive the extension, retraction, and movement of the support ropes, reducing energy consumption and wear on the support ropes.

[0049] 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.

[0050] The embodiments of this application achieve the following technical effects: By dynamically adjusting the height of the supporting part, the falling height of each subsequent pallet is small and constant, greatly reducing the impact force and effectively protecting the quality and integrity of fruits and vegetables. Simultaneously, the embodiments of this application automate pallet stacking and unloading, replacing traditional manual or extensive mechanical operations, significantly improving the production efficiency and automation level of the packing process, and reducing labor costs and product loss rates.

Detailed Implementation

[0063] To facilitate understanding of this utility model, 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 this utility model 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 this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0064] 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 scope of the invention.

[0065] In related technologies, when handling pallets containing fruits and vegetables during fruit and vegetable packing operations, the pallets are typically dropped directly from the pallet conveyor belt or pushed into the packaging box. This method involves a significant vertical drop during pallet stacking, especially when placing the bottom pallets, which can easily cause damage to the fruits and vegetables inside due to impact.

[0066] In addition, when a pallet moves horizontally along the pallet conveyor belt to be stacked with other pallets, the horizontal movement of the pallet can easily scratch the fruits and vegetables on the other pallets, thereby damaging the surface of the fruits and vegetables.

[0067] Please refer to the following: Figures 1 to 4 To address the aforementioned technical problems, this application provides a fruit and vegetable packing machine 100, applied to fruit and vegetable sorting equipment. The fruit and vegetable packing machine 100 includes a support assembly 10, a support rope 20, a support platform 30, and a drive assembly 40. The support assembly 10 includes two spaced-apart support units 11. The support rope 20 is connected to each of the two support units 11, forming a support portion 21 between the two support units 11. The support rope 20 includes a first end and a second end 22 facing each other. The support platform 30 is located above the support portion 21 and is used to support trays sequentially input and containing fruits and vegetables. The support platform 30 can be opened intermittently to allow trays to be stacked on the support portion 21.

[0068] The drive assembly 40 drives the first end and the second end 22 of the support rope 20 to lower the support 21 when the number of pallets on the support 21 increases, so that the top pallet is kept at a preset height, and to pull the support rope 20 away from the bottom of the pallets when the number of pallets on the support 21 reaches a preset number, so as to unload the stacked pallets.

[0069] The working principle of the fruit and vegetable packing machine 100 in this embodiment is as follows: This embodiment utilizes a support rope 20 connected between two support units 11 to form a liftable support section 21 for supporting stacked pallets. In the initial stage of pallet packing, the pallets are temporarily supported by the upper support platform 30. When the support platform 30 is intermittently opened, the pallets fall onto the support rope 20. As the pallets are stacked one by one, the drive component 40 synchronously drives at least one end of the support rope 20, causing the support section 21 to descend smoothly, ensuring that the top pallet always maintains a small, preset vertical distance from the support platform 30. When the pallets are stacked to a preset number, the drive component 40 quickly pulls the support rope 20 away from the bottom of the entire stack of pallets, thus completing a full stacking and unloading process.

[0070] Understandably, this embodiment of the application dynamically adjusts the height of the supporting part 21, ensuring that the falling height of each subsequent pallet is small and constant, greatly reducing impact and effectively protecting the quality and integrity of fruits and vegetables. Simultaneously, this embodiment of the application automates pallet stacking and unloading, replacing traditional manual or extensive mechanical operations, significantly improving production efficiency and automation levels in the packing process, and reducing labor costs and product loss rates.

[0071] Please see Figure 1 In some embodiments, the fruit and vegetable packing machine 100 further includes a pallet conveyor belt 50, the end of which is connected to a support platform 30 for sequentially outputting pallets containing fruits and vegetables to the support platform 30. The pallet conveyor belt 50 includes two opposing limiting arms 51, located on opposite sides of the pallet conveyor belt 50 along its transport direction. Optionally, the distance between the two limiting arms 51 gradually decreases along the transport direction of the pallet conveyor belt 50 to a preset distance. Specifically, the preset distance is just large enough to accommodate a single pallet passing through, and under the limiting action of the limiting arms 51, the sequentially input pallets align with the previous pallet on the support platform 30, thereby keeping the pallets stacked on the support section 21 aligned.

[0072] For example, in this embodiment of the application, the support rope 20 is controlled to keep the uppermost pallet at a preset height. The preset height may be that the top of the uppermost pallet is level with or slightly below the output end of the pallet conveyor belt 50.

[0073] In other embodiments, manual operation can be combined with the fruit and vegetable packing machine 100 for packing. Specifically, the manual operator sequentially moves the trays containing fruits and vegetables onto the support platform 30 and coordinates with the opening and closing rhythm of the support platform 30 to meet the sequential input of the trays.

[0074] In some embodiments, the fruit and vegetable packing machine 100 further includes a frame 60, on which the pallet conveyor belt 50, support component 10, support platform 30 and drive component 40 are all mounted. In other embodiments, some of the pallet conveyor belt 50, support component 10, support platform 30 and drive component 40 may be mounted on the frame 60, while others may be modules independent of the frame 60.

[0075] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the support platform 30 includes a pull-out plate unit 31 for supporting sequentially input trays. The pull-out plate unit 31 includes a stop member 311, a pull-out plate 312, and a first drive module 313. The stop member 311 is positioned directly opposite the input direction of the tray. The pull-out plate 312 is located between the support portion 21 and the stop member 311 in the height direction. The pull-out plate 312 is movable relative to the stop member 311 directly below it, and its initial position is directly above the support portion 21. The first drive module 313 is connected to the pull-out plate 312 and is used to drive the pull-out plate 312 to intermittently move directly below the stop member 311 so that the trays are stacked on the support portion 21.

[0076] Understandably, the support platform 30 employs a pull-out plate unit 31, which includes a blocking member 311 for positioning and a pull-out plate 312 that can move below the blocking member 311. The sequentially input trays are first conveyed onto the pull-out plate 312 and positively limited by the blocking member 311 to ensure accurate positioning. The first drive module 313 drives the pull-out plate 312 to perform intermittent reciprocating motion in the horizontal direction according to a control signal. When the pull-out plate 312 retracts directly below the blocking member 311, the trays it supports will fall vertically due to loss of support and stack onto the support portion 21 below.

[0077] To be more easily understood, the embodiments of this application, through the cooperation of the pull plate 312 and the blocking member 311, ensure that each pallet is in the correct predetermined position before falling, thus guaranteeing the neatness and stability of subsequent stacking. The intermittent driving method enables precise control of the packing rhythm, allowing it to perfectly match the speed of the front pallet conveyor belt 50, thereby ensuring the continuity and smoothness of the entire packing process.

[0078] In some embodiments, the first drive module 313 includes a first linear drive member and a push plate connector. The first linear drive member is mounted on the frame 60, and the push plate connector is connected to both the push plate and the movable end of the first linear drive member. The first linear drive member can drive the push plate to move via the push plate connector. Optionally, the first linear drive member may be a telescopic cylinder or an electric push rod, etc.

[0079] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the support platform 30 further includes a split panel 32 and a second drive module 33. The split panel 32 is located directly above the support portion 21 and below the pull plate 312 in the height direction. The split panel 32 can be flipped downwards relative to the support portion 21 to open or reset to close. The second drive module 33 is connected to the split panel 32 and is used to drive the split panel 32 to open or close.

[0080] The first pallet supported by the pull plate 312 falls onto the split panel 32 after the pull plate 312 is opened, and then falls onto the support part 21 after the split panel 32 is opened. The split panel 32 remains open after the first pallet falls onto the support part 21, and returns to the closed state after all the pallets stacked on the support part 21 are completely unloaded.

[0081] Understandably, a downward-flipping split panel 32 is added between the pull plate 312 and the support rope 20. For the first pallet in the stack, after the pull plate 312 opens, the pallet does not fall directly onto the support rope 20, but first gently falls onto the closed split panel 32. Subsequently, the second drive module 33 drives the split panel 32 to flip downward, releasing the first pallet onto the support rope 20 with a shorter distance and lower impact force. After this, the split panel 32 will remain open, and subsequent pallets will fall directly from the pull plate 312 onto the stacked pallets. The split panel 32 will only reset and close after the entire stack of pallets has been unloaded, preparing for the next packing cycle.

[0082] This application embodiment breaks down the originally relatively long drop process of the first tray into two shorter drops, reducing the initial impact and minimizing the risk of damage to fruits and vegetables.

[0083] During actual packing, the packaging box or fruit basket is located below the support part 21. As the support part 21 gradually descends, the stacked pallets will enter the interior of the packaging box or fruit basket. For example, the split panel 32 can open the packaging box or fruit basket when it is opened downwards, and it also plays a certain guiding role in the entry of the pallets into the packaging box or fruit basket, making the packing process more stable.

[0084] Please refer to the following: Figure 5 and Figure 6 In some embodiments, the split panel 32 includes two panel units 321, which are arranged sequentially along the length of the support portion 21. The second drive module 33 is connected to each panel unit 321 respectively, and the second drive module 33 is used to drive the two panel units 321 respectively to flip down to open or flip up to reset and close.

[0085] The panel unit 321 is provided with a clearance groove 3211, and each clearance groove 3211 is aligned with a corresponding support rope 20. When the panel unit 321 is flipped downward, each clearance groove 3211 avoids the corresponding support rope 20.

[0086] Understandably, in this embodiment, the split panel 32 is configured as two panel units 321 arranged along the length of the support portion 21, and they are driven to flip synchronously by the second drive module 33. Each panel unit 321 has a clearance groove 3211 corresponding to the position of the support rope 20 below. When the two panel units 321 are flipped downwards and opened, the clearance groove 3211 can bypass the support rope 20, so that the flipping action of the panel will not interfere with the support rope 20.

[0087] Please see Figure 5 In some embodiments, the second drive module 33 includes a first connecting shaft 3301, a second connecting shaft 3302, a first pulley 3303, a second pulley 3304, a third pulley 3305, a fourth pulley 3306, a first synchronous belt 3307, a second synchronous belt 3308, a first drive shaft 3309, a second drive shaft 3310, a first gear 3311, a second gear 3312, and a first drive motor 3313. The first connecting shaft 3301, the second connecting shaft 3302, the first drive shaft 3309, and the second drive shaft 3310 are parallel to each other and are respectively mounted on the frame 60. The first connecting shaft 3301, the second connecting shaft 3302, the first drive shaft 3309, and the second drive shaft 3310 are all perpendicular to the supporting rope 20. The first connecting shaft 3301 is connected to one of the panel units 321, and the second connecting shaft 3302 is connected to the other panel unit 321. The first pulley 3303 is coaxially and fixedly connected to the first connecting shaft 3301, and the second pulley 3304 is coaxially and fixedly connected to the second connecting shaft 3302. The first gear 3311 and the third pulley 3305 are coaxially and fixedly connected to the first drive shaft 3309, respectively, and the second gear 3312 and the fourth pulley 3306 are coaxially and fixedly connected to the second drive shaft 3310, respectively. The first synchronous belt 3307 is sleeved on the first pulley 3303 and the third pulley 3305, and is engaged with the first pulley 3303 and the third pulley 3305, respectively. The second synchronous belt 3308 is sleeved on the second pulley 3304 and the fourth pulley 3306, and is engaged with the second pulley 3304 and the fourth pulley 3306, respectively. The first gear 3311 and the second gear 3312 mesh with each other, and the first drive motor 3313 is connected to the first drive shaft 3309.

[0088] Understandably, the first drive motor 3313 drives the first drive shaft 3309 to rotate, causing the third pulley 3305 and the first gear 3311 to rotate. Through meshing transmission and belt transmission, the first pulley 3303 and the second pulley 3304 rotate, thereby causing the first connecting shaft 3301 and the second connecting shaft 3302 to rotate. Under the rotation of the first connecting shaft 3301 and the second connecting shaft 3302, the two panel units 321 together flip downwards to open or flip upwards to reset.

[0089] Please see Figure 6 In other embodiments, the second drive module 33 includes two panel control units 3314, each panel control unit 3314 including a third connecting shaft 33141, a connecting rod 33142, and a second linear drive member 33143. Each third connecting shaft 33141 is mounted on the frame 60 and connected to a corresponding panel unit 321. One end of each connecting rod 33142 is fixedly connected to a corresponding third connecting shaft 33141, and the other end of each connecting rod 33142 is hinged to the movable end of a corresponding second linear drive member 33143. Each second linear drive member 33143 is hinged to the frame 60. The second linear drive member 33143 may be a telescopic cylinder or an electric push rod, etc.

[0090] Understandably, the extension and retraction of the second linear drive 33143 causes the connecting rod 33142 to move, and the connecting rod 33142 causes the third connecting shaft 33141 to rotate around its axis, thereby causing the corresponding panel unit 321 to flip. Furthermore, by synchronously controlling the two linear drive assemblies, the two panel units 321 can be flipped downwards to open or flipped upwards to reset together under the rotation of the corresponding third connecting shaft 33141.

[0091] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the drive assembly 40 includes a winding mechanism 41 and a gripping mechanism 42. The winding mechanism 41 is connected to a first end of the support rope 20 and is used to wind up and unwind the support rope 20. The gripping mechanism 42 is connected to a second end 22 of the support rope 20 and is movable relative to the winding mechanism 41 to approach or move away from the winding mechanism 41. The gripping mechanism 42 is used to grip or release the second end 22.

[0092] When the number of pallets on the support section 21 increases, the rope grabbing mechanism 42 drives the second end 22 to move and approach the rope winding mechanism 41, so as to lower the support section 21 and keep the uppermost pallet at a preset height.

[0093] When the number of pallets on the support section 21 reaches a preset number, the rope gripping mechanism 42 releases the second end 22, and the rope winding mechanism 41, in cooperation with the rope gripping mechanism 42, winds up the support rope 20, pulling the support rope 20 away from under the pallets to unload the stacked pallets. After the stacked pallets are completely unloaded, the rope gripping mechanism 42 can move closer to the rope winding mechanism 41 and re-grip the second end 22, and after gripping the second end 22, it can move away from the rope winding mechanism 41 back to the initial position, and the rope winding mechanism 41 can cooperate with the rope gripping mechanism 42 to rewind the support rope 20.

[0094] Understandably, in this embodiment, the drive assembly 40 is divided into a rope winding mechanism 41 located at the first end of the support rope 20 and a rope gripping mechanism 42 located at the second end 22. During the stacking and descent process, the rope gripping mechanism 42 clamps the second end 22 of the support rope 20 and simultaneously releases the support rope 20 by translating itself towards the rope winding mechanism 41, thereby achieving a smooth descent of the support portion 21. When unloading the pallet, the rope gripping mechanism 42 first releases the second end 22 of the rope, and then the rope winding mechanism 41 quickly winds up the entire support rope 20 completely from the first end, completing the extraction action. During the reset phase, the rope gripping mechanism 42 moves and re-grips the end of the rope, then moves in the opposite direction to the initial position, while the rope winding mechanism 41 cooperates to release the support rope 20 and re-tension the support portion 21.

[0095] During the descent phase, the fruit and vegetable packing machine 100 achieves smooth and precise height changes between the support section 21 and the pallet through the translational control of the rope-grabbing mechanism 42. During the unloading phase, the fruit and vegetable packing machine 100 achieves a fast and thorough rope-pulling action by releasing one end and quickly winding it up from the other end, thus improving unloading efficiency.

[0096] Please see Figure 3 , Figure 4 as well as Figure 7 In some embodiments, the rope winding mechanism 41 includes a reel 411, a rotating shaft 412, and a third drive module 413. The reel 411 is connected to the first end of the supporting rope 20. The rotating shaft 412 is coaxially and fixedly connected to the reel 411. The third drive module 413 is connected to the rotating shaft 412 and is used to drive the rotating shaft 412 to rotate, thereby driving the reel 411 to wind up or unwind the supporting rope 20.

[0097] Understandably, the rope winding mechanism 41 includes a reel 411 for directly winding the support rope 20, a rotating shaft 412 coaxially fixed with the reel 411, and a third drive module 413 for providing rotational power. The third drive module 413 drives the rotating shaft 412 to rotate, which in turn drives the reel 411 to rotate synchronously, thereby realizing the winding or unwinding function of the support rope 20. The above-mentioned configuration of the rope winding mechanism 41 can provide a stable and controllable power source for the winding and unwinding of the support rope 20, ensuring that the support rope 20 can be quickly and smoothly wound and unwound during unloading and resetting, thus ensuring the efficiency and reliability of the entire equipment's cyclic operation.

[0098] In some embodiments, the third drive module 413 includes a fifth pulley 4131, a sixth pulley 4132, a third synchronous belt 4133, and a second drive motor 4134. The fifth pulley 4131 is coaxially and fixedly connected to the rotating shaft 412, and the sixth pulley 4132 is connected to the second drive motor 4134. The third synchronous belt 4133 is respectively sleeved on the fifth pulley 4131 and the sixth pulley 4132, and is respectively engaged and connected with the fifth pulley 4131 and the sixth pulley 4132.

[0099] Understandably, the second drive motor 4134 drives the sixth pulley 4132, which in turn drives the fifth pulley 4131 to rotate via the third synchronous belt 4133. The rotating shaft 412 follows the rotation of the fifth pulley 4131, so that the reel 411 can wind up or unwind the supporting rope 20.

[0100] Please refer to the following: Figure 7 and Figure 8 In some embodiments, the rope-grabbing mechanism 42 includes a slide rail 421, a finger-grip cylinder 422, a connecting arm 423, a slider 424, and a fourth drive module 425. The rope-winding mechanism 41 is located along the extension direction of the slide rail 421. The finger-grip cylinder 422 is connected to the second end 22 of the supporting rope 20 and is used to grip or release the second end 22. The connecting arm 423 is connected to the finger-grip cylinder 422. The slider 424 is connected to both the connecting arm 423 and the slide rail 421, and the slider 424 is movable relative to the slide rail 421. The fourth drive module 425 is connected to the slider 424 and is used to drive the slider 424 to move relative to the slide rail 421, thereby causing the finger-grip cylinder 422 to move closer to or away from the rope-winding mechanism 41 via the connecting arm 423.

[0101] Understandably, the rope gripping mechanism 42 is equipped with a finger-grip cylinder 422 to clamp or release the second end 22 of the supporting rope 20. The finger-grip cylinder 422 is fixed to the slider 424 via a connecting arm 423, and the slider 424 is mounted on the slide rail 421. The fourth drive module 425 drives the slider 424 to move precisely back and forth along the slide rail 421, thereby driving the finger-grip cylinder 422 to move as a whole, realizing the action of moving closer to or away from the rope winding mechanism 41. This ensures stable gripping or release of the supporting rope 20 under various working conditions, guaranteeing the smoothness of the packing machine during the stacking and descent phase and the accuracy during the unloading and resetting phase.

[0102] In some embodiments, the fourth drive module 425 includes a seventh pulley 4251, an eighth pulley 4252, a fourth conveyor belt 4253, and a third drive motor 4254. The seventh pulley 4251 and the eighth pulley 4252 are respectively disposed at both ends of the slider 424. The fourth conveyor belt 4253 is respectively sleeved on the seventh pulley 4251 and the eighth pulley 4252 and is connected to the seventh pulley 4251 and the eighth pulley 4252 respectively. The third drive motor 4254 is connected to the eighth pulley 4252. The slider 424 is fixedly connected to the fourth conveyor belt 4253.

[0103] Understandably, the third drive motor 4254 drives the eighth pulley 4252 to rotate, thereby moving the fourth conveyor belt 4253 and causing the slider 424 to slide on the slide rail 421. The slider 424 then drives the finger-grip cylinder 422 to move closer to or away from the rope winding mechanism 41 via the connecting arm 423.

[0104] Please review Figure 7 In some other embodiments, the fourth drive module 425 further includes a ninth pulley 4255, a tenth pulley 4256, and a fifth synchronous belt 4257. The ninth pulley 4255 and the eighth pulley 4252 are coaxially connected and can rotate synchronously. The fifth synchronous belt 4257 is respectively sleeved on the ninth pulley 4255 and the tenth pulley 4256. The third drive motor 4254 is connected to the tenth pulley 4256 and drives it to rotate through the tenth pulley 4256, so that the eighth pulley 4252 rotates, thereby driving the fourth conveyor belt 4253.

[0105] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the rope gripping mechanism 42 further includes a receiving arm 426 and a cable chain 427. The receiving arm 426 is arranged parallel to the slide rail 421 and located below the connecting arm 423. The receiving arm 426 is provided with an upward-facing receiving groove 4261. The cable chain 427 is received in the receiving groove 4261, and the air pipe of the finger-gripping cylinder 422 is housed inside the cable chain 427.

[0106] Understandably, a receiving arm 426 with an upward-opening receiving groove 4261 is arranged parallel to the slide rail 421, and a cable chain 427 is laid inside the receiving groove 4261. The air pipe that supplies air to the finger gripper cylinder 422 is housed inside the cable chain 427. When the finger gripper cylinder 422 moves along the slide rail 421 with the slider 424, the air pipe will bend and unfold in an orderly manner under the protection and guidance of the cable chain 427, without being dragged randomly or tangled with other parts, thus preventing it from being worn due to bending, friction or scratching during long-term reciprocating motion.

[0107] Please refer to the following: Figure 8 and Figure 9 In some embodiments, there are multiple support ropes 20, which are arranged in parallel and spaced apart. The support unit 11 includes pulleys 111, each pulley 111 can roll against a corresponding support rope 20, and the axes of each pulley 111 in each support unit 11 are arranged coaxially.

[0108] Understandably, this embodiment replaces the single support surface with multiple parallel and spaced support ropes 20. Correspondingly, each support rope 20 is equipped with a rolling pulley 111 for support and guidance on the support units 11 at both ends. To simplify the structure and ensure synchronization, all pulleys 111 in each support unit 11 are coaxially aligned, resulting in more uniform and stable support for the bottom of the pallet, effectively preventing the pallet from tilting or swaying during descent or support. The application of pulleys 111 significantly reduces the friction of the support ropes 20 during movement, allowing the drive assembly 40 to use less force to drive the ropes' extension and retraction, reducing energy consumption and wear on the support ropes 20.

[0109] Please see Figures 1 to 4 In another aspect, embodiments of this application provide a fruit and vegetable sorting device, including a fruit and vegetable packing machine 100 as described above.

[0110] It is understandable that the embodiments of this application extend and apply the advantages of the aforementioned fruit and vegetable packing machine 100 in flexible packing and protecting fruits and vegetables to the entire fruit and vegetable sorting equipment, thereby improving the overall production efficiency and the quality of fruits and vegetables.
