Description

Technical Field

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

[0002] Vertical packing machines, common equipment in automated production lines, are primarily used to receive fruits and vegetables from the end of a conveyor belt and transfer them to another location, such as boxes or crates, via vertical lifting. During the fruit and vegetable packing process, the weight of each box needs to be controlled to minimize weight variations between packing operations.

[0003] However, existing vertical packing machines typically only have lifting and conveying functions. Their design focuses primarily on the stability of the mechanical structure and lifting efficiency, and the equipment itself does not integrate weighing functionality. If it is necessary to obtain the weight of the fruits and vegetables inside the box, it is often necessary to transfer the box containing the fruits and vegetables to a separate weighing device for weighing, or to quantitatively add the weighed fruits and vegetables before packing. The process is relatively cumbersome, and it is difficult to monitor weight changes in real time during lifting and transfer, and it is also difficult to control the packing based on real-time weight. Utility Model Content

[0004] One objective of this application is to provide a lifting box assembly, a vertical boxing machine, and a fruit and vegetable sorting device to solve the technical problem in the related art that vertical boxing machines are unable to weigh the fruit and vegetable boxes in real time.

[0005] In a first aspect, embodiments of this application provide a lifting box assembly, comprising: frame; The housing is mounted on the frame and is capable of sliding relative to the frame in the height direction. A traction mechanism is installed on the frame and connected to the housing; the traction mechanism is used to pull the housing up or down. A weighing sensor is installed on the frame or at the connection between the traction mechanism and the box. The weighing sensor is used to weigh the fruits and vegetables inside the box.

[0006] The above structure integrates the weighing sensor into the lifting box assembly, thus integrating the weighing function with the receiving, lifting, and transfer process of fruits and vegetables. Since the weighing sensor can monitor the weight of the fruits and vegetables inside the box in real time, the timing of unloading can be flexibly adjusted based on the monitored weight, thereby reducing weight variations in each vertical loading and transfer.

[0007] Optionally, the traction mechanism includes: The first motor is mounted on the frame and located above the housing; The first tape, the axis of which rotates is controlled by the first motor, is connected at one end to the weighing sensor and at the other end to the housing.

[0008] With the above structure, the traction mechanism uses a motor-driven belt winding method to achieve the lifting and lowering of the box.

[0009] Optionally, the traction mechanism further includes: The first connector connects the end of the first tape and one end of the weighing sensor, respectively. The second connector connects the other end of the weighing sensor to the housing. An anti-detachment component is provided, which connects the first connector and the second connector respectively. The anti-detachment component is used to prevent the first connector and the second connector from detaching from each other when the weighing sensor breaks, so as to prevent the housing from being driven by the first motor.

[0010] With the above structure, when the load cell fails or breaks, the anti-detachment component can connect the first and second connecting components, forming a backup force transmission path. Even if the load cell is damaged, the housing remains connected to the first conveyor belt through the anti-detachment component, preventing it from falling immediately and thus avoiding serious accidents.

[0011] Optionally, the anti-detachment component includes a fastening part and a first limiting part, the fastening part and the first limiting part being fixedly disposed relative to each other in the direction from the first connector to the second connector, the fastening part being fixedly connected to one of the first connector and the second connector, the other of the first connector and the second connector being closer to the first limiting part than the other one, and the first limiting part being used to limit the other of the first connector and the second connector or to limit the other of the first connector and the second connector when the weighing sensor breaks.

[0012] Through the above structure, the fixed connection of the fastening part and the limiting function of the first limiting part ensure that even after the weighing sensor fails, the box can still be connected to the traction mechanism through the anti-detachment component, preventing the box from falling freely and improving the safety of the equipment.

[0013] Optionally, the anti-detachment component includes a limiting engagement part and a second limiting part. The limiting engagement part and the second limiting part are fixedly disposed relative to each other in the direction from the first connecting member to the second connecting member. The limiting engagement part abuts against the first connecting member and is located above the first connecting member, and the second limiting part is located below the second connecting member. The second limiting part is used to limit the second connecting member when the weighing sensor breaks.

[0014] Through the above structure, the combined action of the limiting and the second limiting part restricts the relative separation of the first and second connecting parts, so that the box can still be constrained by the traction mechanism after the weighing sensor fails, thus preventing it from falling.

[0015] Optionally, the traction mechanism includes: The second motor is mounted on the frame and located on the side of the housing; A support roller is mounted on the frame and located on the same side of the housing as the second motor, with the support roller being closer to the housing than the second motor. The second tape, the axis of which rotates is controlled by the second motor, and the end of the second tape is connected to one end of the weighing sensor; A connecting belt, one end of which is connected to the other end of the weighing sensor, and the other end of which is connected to the housing, wherein the belt surface is configured to partially conform to and be supported by the support roller.

[0016] With the above structure, the second motor is mounted on the frame and located on the side of the box, which helps to reduce the overall height of the equipment. Since the box is located at the output end of the fruit and vegetable conveyor belt, the second motor, the second belt reel, the support roller and the connecting belt can be located below the fruit and vegetable conveyor belt to improve the space utilization of the vertical boxing machine.

[0017] Optionally, the housing is provided with a side opening, and the other end of the connecting strap is connected to the bottom of the side opening; The connecting strap is configured to close the side opening when the housing is lowered and to open the side opening when the housing is raised.

[0018] Through the above structure, the connecting belt, as it wraps around the support roller, gradually blocks or closes the side openings, preventing fruits and vegetables from accidentally falling out during descent. When the container finishes unloading and begins to rise, the connecting belt is driven by a second motor via a second winding belt and a weighing sensor. The connecting belt, used to block or close the side openings, repositions itself around the support roller to lift the entire container. The lifting drive component is integrated with the feeding gate control component, simplifying the structure, reducing additional drive devices and control links, and improving the system's integration and reliability.

[0019] Optionally, the frame includes a first frame and a second frame, the first frame being located above the second frame, the weighing sensor being fixedly connected to the first frame and the second frame respectively, and the traction mechanism and the housing being mounted on the first frame.

[0020] With the above structure, the entire weight of the first frame and all components mounted on it is transferred to the second frame via load cells. In this configuration, the load cells measure the weight of the entire superstructure, including the first frame, the traction mechanism, the box, and the total weight of the fruits and vegetables.

[0021] In a second aspect, embodiments of this application provide a vertical packing machine, comprising: Fruit and vegetable conveyor belts are used to transport fruits and vegetables. As described in any of the above, the lifting box assembly has its box body located at the output end of the fruit and vegetable conveyor belt and a fruit and vegetable container disposed below it. The lifting box assembly is used to receive the fruits and vegetables on the fruit and vegetable conveyor belt through the box body and transfer the fruits and vegetables to the fruit and vegetable container below.

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

[0023] The embodiments of this application can achieve the following technical effects: The lifting box assembly provided in this application integrates a weighing sensor into the lifting box assembly, thereby integrating the weighing function with the receiving, lifting, and transfer process of fruits and vegetables. Since the weighing sensor can monitor the weight of the fruits and vegetables inside the box in real time, the timing of unloading the box can be flexibly adjusted according to the monitored weight of the fruits and vegetables, so as to reduce the weight difference of fruits and vegetables in each vertical loading and transfer.

[0027] 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.

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 scope of the invention.

[0029] In related technologies, vertical packing machines have difficulty monitoring and controlling the weight of fruits and vegetables in real time during the packing process, resulting in excessive weight differences among the fruits and vegetables in each packing box or basket, making it difficult to ensure the consistency of weight of each box or basket.

[0030] Please see Figure 1In order to solve the above problems, in a first aspect, this application provides a lifting box assembly 100, which is applied to a vertical boxing machine 1000. The lifting box assembly 100 is used to receive and transport fruits and vegetables.

[0031] In some embodiments, the lifting box assembly 100 includes a frame 10, a box body 20, a traction mechanism 30, and a load cell 40. The box body 20 is mounted on the frame 10 and is capable of sliding relative to the frame 10 in the height direction. The traction mechanism 30 is mounted on the frame 10 and connected to the box body 20, and is used to lift or lower the box body 20. The load cell 40 is mounted on the frame 10 or at the connection between the traction mechanism 30 and the box body 20, and is used to weigh the fruits and vegetables inside the box body 20.

[0032] The working principle of the lifting box assembly 100 in this embodiment is as follows: When the lifting box assembly 100 is started, the box body 20 is located at the receiving position, for example, the output end of the fruit and vegetable conveyor belt 200. Fruits and vegetables fall from the conveyor belt 200 into the box body 20. The weighing sensor 40 monitors the weight of the fruits and vegetables in the box body 20 in real time. The output signal of the weighing sensor 40 can be used to provide the operator with the weight information of the fruits and vegetables in the box body 20, or it can be directly used to control the start and stop of the traction mechanism 30, etc.

[0033] Understandably, the lifting box assembly 100 provided in this application integrates the weighing sensor 40 into the lifting box assembly 100, thereby integrating the weighing function with the receiving, lifting, and transfer process of fruits and vegetables. Since the weighing sensor 40 can monitor the weight of the fruits and vegetables inside the box 20 in real time, the timing of unloading from the box 20 can be flexibly adjusted based on the monitored weight of the fruits and vegetables, so as to reduce the weight difference of fruits and vegetables in each vertical loading and transfer.

[0034] In some embodiments, the frame 10 may be provided with a limiting structure so that the housing 20 can slide only in the height direction. See also Figure 2 Alternatively, one of the frame 10 and the housing 20 may be equipped with a slide rail 11, and the other with a slider 21. The slide rail 11 extends along the height direction of the frame 10, and the slider 21 and the slide rail 11 are connected to each other, so that the housing 20 can slide relative to the frame 10 in the height direction.

[0035] Please refer to the following: Figure 3 and Figure 4 In other embodiments, the frame 10 includes columns 12, and the housing 20 is equipped with at least one pair of guide wheels 22. A corresponding column 12 is accommodated between the two guide wheels of the same pair, and the guide wheels 22 roll against the column 12 to restrict the housing 20 to slide only along the length of the column 12. Designers can set the specific shape, number, and position of the columns 12 and rollers according to experience and actual needs; no restrictions are imposed here.

[0036] In some embodiments, the signal from the weighing sensor 40 is used to provide the operator with weight information of the fruits and vegetables inside the box 20. For example, the weighing sensor 40 is connected to a display device, and the display device shows the weight value of the fruits and vegetables inside the box 20. For example, the display device can be a device capable of human-computer interaction, or it can simply provide a display function. For further examples, the display device can be a handheld terminal device, a display screen, or a console or control panel. The operator controls the traction mechanism 30, the fruit and vegetable conveyor belt 200, etc., respectively, based on the fruit and vegetable weight information on the display device to complete the vertical boxing operation.

[0037] In other embodiments, the signal from the weighing sensor 40 is directly used to control the start and stop of the traction mechanism 30. The weighing sensor 40 can be connected to the control system of the vertical boxing machine 1000. The control system is connected to and controls devices such as the traction mechanism 30 and the fruit and vegetable conveyor belt 200. The control system can accurately control the amount of fruit and vegetables packed each time based on real-time weight data, thereby significantly reducing the weight difference between different boxes or baskets and ensuring weight consistency.

[0038] When the weight of the fruits and vegetables inside the container 20 reaches a preset value, the weighing sensor 40 sends a signal to the control system, for example, to stop the feeding of the fruit and vegetable conveyor belt 200. Subsequently, the traction mechanism 30 starts, pulling the container 20 down to a preset unloading position, such as above or inside a packaging box or fruit basket. The container 20 unloads the fruits and vegetables into the packaging box or fruit basket. After unloading, the traction mechanism 30 then pulls the empty container 20 back up to the receiving station, ready for the next fruit and vegetable packing operation.

[0039] Throughout the process, the weighing sensor 40 operates continuously, monitoring the weight not only when receiving fruits and vegetables but also during transport, and recording the actual weight of each shipment via the control system. Furthermore, in this way, the lifting container assembly 100 achieves automated and integrated operation of fruit and vegetable receiving, weighing, transporting, and unloading.

[0040] In some embodiments, the control system connected to the weighing sensor 40 may be composed of devices and functional modules such as a programmable logic controller (PLC) or a microcontroller unit (MCU). The weighing sensor 40 outputs an electrical signal or wireless signal proportional to the weight of the fruits and vegetables it carries. The control system is connected to the traction mechanism 30 and controls the start and stop of the traction mechanism 30. Exemplarily, the control system includes a programmable logic controller, and the traction mechanism 30 includes an electric cylinder and a connecting component. The connecting component is a rigid or flexible structural component that connects the electric cylinder and the housing 20 respectively. The electric cylinder is mounted on the frame 10 and located above the housing 20, and drives the housing 20 to rise and fall through the connecting component. The programmable logic controller is connected to the weighing sensor 40 and the electric cylinder respectively, and drives the electric cylinder to work according to the signal sent by the weighing sensor 40.

[0041] In some embodiments, the load cell 40 may be an S-type force sensor, which meets the requirements for both tensile and compressive force testing and can be flexibly arranged on the lifting box assembly 100. In other embodiments, the load cell 40 may also be a compression load cell, a strain gauge load cell, etc., and there is no limitation here.

[0042] Please refer to the following: Figure 1 and Figure 5 In some embodiments, the traction mechanism 30 includes a first motor 31 and a first belt 32. The first motor 31 is mounted on the frame 10 and located above the housing 20. The rotation of the axis of the first belt 32 is controlled by the first motor 31, and one end of the first belt 32 is connected to one end of a load cell 40, the other end of which is connected to the housing 20.

[0043] Understandably, the traction mechanism 30 uses a motor-driven belt winding method to achieve the lifting and lowering of the housing 20. The first motor 31, as the power source, is mounted on the frame 10 and located above the housing 20, facilitating the vertical traction of the housing 20 via the belt winding. The first belt winding 32 can be a belt, chain, or steel rope equipped with a reel or drum. The reel or drum of the first belt winding 32 is connected to the drive shaft of the first motor 31, and the other end is connected to one end of the load cell 40. The other end of the load cell 40 is then connected to the housing 20. Through the series structure, the load cell 40 is directly located on the path of the lifting force transmission.

[0044] When the first motor 31 drives the first tape reel 32 to wind up or unwind, the box 20 rises or falls accordingly. Since the weighing sensor 40 is connected in series between the tape reel and the box 20, the entire weight of the box 20 and the fruits and vegetables inside it acts on the weighing sensor 40, enabling the weighing sensor 40 to measure the weight of the fruits and vegetables inside the box 20 in real time and accurately. Specifically, in this embodiment, the weight of the fruits and vegetables inside the box 20 can be obtained by subtracting the fixed weight of the box 20 from the weighing value taken by the weighing sensor 40.

[0045] Please see Figure 6 In some embodiments, the traction mechanism 30 further includes a first connector 33, a second connector 34, and an anti-detachment component 35. The first connector 33 is connected to one end of the first tape 32 and one end of the load cell 40. The second connector 34 is connected to the other end of the load cell 40 and the housing 20. The anti-detachment component 35 is connected to the first connector 33 and the second connector 34, and is used to prevent the first connector 33 and the second connector 34 from detaching from each other when the load cell 40 breaks, thereby preventing the housing 20 from being disengaged from the drive of the first motor 31.

[0046] Understandably, the first connector 33 and the second connector 34 serve as interfaces at both ends of the load cell 40, respectively, to stably connect it to the traction mechanism 30 and the housing 20, ensuring that force is effectively transmitted through the load cell 40. More easily understood, the load cell 40, as a precision measuring element, is at risk of breakage under extreme overload or fatigue failure. If the load cell 40 breaks, without the anti-detachment component 35, the housing 20 will lose the restraint of the traction mechanism 30 and fall, potentially causing equipment damage, spoilage of fruits and vegetables, or even a safety accident. When the load cell 40 fails and breaks, the anti-detachment component 35 connects the first connector 33 and the second connector 34, forming a backup force transmission path. Even if the load cell 40 is damaged, the housing 20 remains connected to the first conveyor belt 32 via the anti-detachment component 35, preventing immediate fall and thus avoiding serious accidents.

[0047] In other embodiments, the traction mechanism 30 may also use other types of driving components such as cylinders to drive the box 20 to rise and fall, which is not limited here.

[0048] In some embodiments, the anti-detachment member 35 includes a fastening portion and a first limiting portion, which are fixedly disposed relative to each other in the direction from the first connector 33 to the second connector 34. The fastening portion is fixedly connected to one of the first connector 33 and the second connector 34, and the other of the first connector 33 and the second connector 34 is closer to the first limiting portion than the other one. The first limiting portion is used to be limited by the other of the first connector 33 and the second connector 34 or to limit the other of the first connector 33 and the second connector 34 when the weighing sensor 40 breaks.

[0049] Understandably, the anti-detachment component 35 includes a fastening part and a first limiting part, which are relatively fixed in the direction from the first connecting member 33 to the second connecting member 34, that is, they are relatively fixed approximately along the direction of gravity or traction. The fastening part is fixedly connected to one of the first connecting member 33 and the second connecting member 34, while the other part, which is not fixedly connected to the fastening part, is located between the fastening part and the first limiting part.

[0050] During normal operation, the load cell 40 bears the load, and a small gap can be provided between the first limiting part and the nearest connecting part. When the load cell 40 breaks unexpectedly, the two connecting parts originally connected by the load cell 40 will attempt to separate. At this time, the connecting parts without fastening parts will move relative to each other until they contact and are blocked by the first limiting part, or the first limiting part blocks the connecting parts without fastening parts, thereby preventing further separation of the two connecting parts.

[0051] To be more easily understood, the fastening connection and the limiting effect of the first limiting part ensure that even if the weighing sensor 40 fails, the box 20 can still be connected to the traction mechanism 30 through the anti-detachment part 35, preventing the box 20 from falling freely and improving the safety of the equipment.

[0052] For example, the anti-detachment component 35 is a bolt, the fastening part is the threaded end of the bolt, and the first limiting part is the bolt head. The first connecting member 33 has a threaded hole that mates with the bolt thread, and the second connecting member 34 has a through hole that avoids the bolt. The threaded end of the bolt passes through the through hole of the second connecting member 34 and the threaded hole of the first connecting member 33 in sequence, and mates with the threaded hole of the first connecting member 33. The bolt head size is larger than the through hole size. When the load cell 40 breaks, the second connecting member 34 tends to fall along with the housing 20. When it is limited by the bolt head of the bolt, it pulls the housing 20. Under the action of the bolt, the first connecting member 33 and the second connecting member 34 remain relatively fixed, and the housing 20 can still rise or fall under the traction of the traction mechanism 30.

[0053] In other embodiments, the anti-detachment component 35 includes a limiting engagement portion and a second limiting portion, which are fixedly disposed relative to each other in the direction from the first connector 33 to the second connector 34. The limiting engagement portion abuts against the first connector 33 and is located above the first connector 33, while the second limiting portion is located below the second connector 34. The second limiting portion is used to limit the second connector 34 when the weighing sensor 40 breaks.

[0054] Understandably, the anti-slip component 35 includes a limiting engagement portion and a second limiting portion, both of which are relatively fixed in the direction from the first connector 33 to the second connector 34, that is, approximately fixed in the direction of gravity or traction. The limiting engagement portion is configured to contact or be adjacent to the upper surface of the first connector 33. The second limiting portion is located below the lower surface of the second connector 34.

[0055] During normal operation, the load cell 40 connects the first connector 33 and the second connector 34 and bears the load. Small gaps can be provided between the lower surface of the second connector 34 and the second limiting part, and between the upper surface of the first connector 33 and the limiting mating part, to ensure that the load cell 40 is subjected to normal force. When the load cell 40 breaks, the second connector 34 will move downwards due to the gravity of the box 20 and the fruits and vegetables until its lower surface is supported by the second limiting part. Simultaneously, the first connector 33 will be subjected to traction, and its upper surface will abut against the limiting mating part.

[0056] To be more easily understood, the combined action of the limiting engagement part and the second limiting part restricts the relative separation of the first connecting member 33 and the second connecting member 34, so that the box 20 can still be constrained by the traction mechanism 30 after the weighing sensor 40 fails, thus preventing it from falling.

[0057] For example, the anti-detachment component 35 includes a bolt and a nut that cooperate with each other. The first connecting member 33 and the second connecting member 34 are respectively provided with through holes that are aligned with each other and avoid the bolt. The bolt passes through the first connecting member 33 and the second connecting member 34 and is connected to the nut. One of the bolt head and the nut serves as a limiting mating part located above the first connecting member 33 and is larger than the through hole size of the first connecting member 33. The other serves as a second limiting part located below the second connecting member 34 and is larger than the through hole size of the second connecting member 34. When the weighing sensor 40 breaks, the second connecting member 34 tends to fall along with the housing 20. One of the bolt head and the nut is abutted and limited by the first connecting member 33, and the other abuts and limits the second connecting member 34 to hold the housing 20 in place. Under the action of the bolt and the nut, the first connecting member 33 and the second connecting member 34 remain relatively fixed, and the housing 20 can still rise or fall under the traction of the traction mechanism 30.

[0058] Please refer to the following: Figure 3 , Figure 7 and Figure 8In some embodiments, the traction mechanism 30 includes a second motor 36, a support roller 37, a second belt 38, and a connecting belt 39. The second motor 36 is mounted on the frame 10 and located to the side of the housing 20. The support roller 37 is mounted on the frame 10 and located on the same side of the housing 20 as the second motor 36, but closer to the housing 20 than the second motor 36. The axis rotation of the second belt 38 is controlled by the second motor 36, and one end of the second belt 38 is connected to one end of a load cell 40. One end of the connecting belt 39 is connected to the other end of the load cell 40, and the other end of the connecting belt 39 is connected to the housing 20. The surface of the connecting belt 39 is configured to partially conform to and be supported by the support roller 37.

[0059] Understandably, mounting the second motor 36 on the frame 10 and placing it to the side of the box 20 helps reduce the overall height of the equipment. Since the box 20 is located at the output end of the fruit and vegetable conveyor belt 200, the second motor 36, the second belt reel 38, the support roller 37, and the connecting belt 39 can be positioned below the fruit and vegetable conveyor belt 200 to improve the space utilization of the vertical boxing machine 1000. To effectively convert the lateral motor drive force into the vertical lifting motion of the box 20, the support roller 37 is provided. The support roller 37 is also located to the side of the box 20, but closer to the box 20 than the second motor 36. The second belt reel 38 can be a belt, chain, or steel rope equipped with a reel or drum. The reel or drum of the second belt reel 38 is connected to the drive shaft of the second motor 36, and the end of the second belt reel 38 is connected to one end of the load cell 40. The other end of the load cell 40 is connected to the box 20 via the connecting belt 39. The connecting belt 39 bypasses the support roller 37, which acts as a fulcrum, altering the direction of the connecting belt 39 and allowing it to vertically lift or lower the box 20. A load cell 40 is connected in series in the force transmission path, enabling accurate measurement of the weight of the fruits and vegetables inside the box 20. Specifically, when the second motor 36 releases the second roll 38, the connecting belt 39 lowers the box 20 around the support roller 37; when the second electrode coils the second roll 38, the connecting belt 39 retracts and resets around the support roller 37. In this embodiment, the weight of the fruits and vegetables inside the box 20 is obtained by subtracting the fixed weight of the box 20 from the weighing value measured by the load cell 40.

[0060] In some embodiments, the housing 20 is provided with a side opening 23, and the other end of the connecting strap 39 is connected to the bottom of the side opening 23. The connecting strap 39 is configured to close the side opening 23 when the housing 20 is lowered and to open the side opening 23 when the housing 20 is raised.

[0061] Understandably, this application embodiment provides a clever way to simultaneously control the state setting of the side opening 23 of the box 20 using the connecting belt 39. The box 20 itself has a side opening 23 for unloading fruits and vegetables. The end of the connecting belt 39 that passes around the support roller 37 and connects to the weighing sensor 40 is not connected to the traditional lifting point of the box 20, but rather to the bottom edge of the side opening 23, so that the belt surface of the connecting belt 39 after passing around the support roller 37 can directly affect the opening and closing of the side opening 23.

[0062] As the container 20 descends, the connecting belt 39, wrapping around the support roller 37, gradually blocks or closes the side opening 23 to prevent fruits and vegetables from accidentally falling out during descent. When the container 20 finishes unloading and begins to rise, the connecting belt 39 is driven by the second motor 36 via the second winding belt 38 and the weighing sensor 40. The connecting belt 39, used to block or close the side opening 23, returns to its original position around the support roller 37 to lift the entire container 20. The lifting drive component is integrated with the feeding gate control component, simplifying the structure, reducing additional drive devices and control links, and improving the system's integration and reliability.

[0063] Please see Figure 9 In some embodiments, the frame 10 includes a first frame 14 and a second frame 15, with the first frame 14 located above the second frame 15. Weighing sensors 40 are fixedly connected to the first frame 14 and the second frame 15 respectively, and the traction mechanism 30 and the housing 20 are installed on the first frame 14.

[0064] Understandably, the frame 10 includes a first frame 14 and a second frame 15, with the first frame 14 positioned above the second frame 15. A load cell 40 acts as a connector, securely linking the first frame 14 and the second frame 15. The entire weight of the first frame 14 and all components mounted on it is transferred to the second frame 15 via the load cell 40. In this configuration, the load cell 40 measures the weight of the entire superstructure, including the first frame 14, the traction mechanism 30, the box 20, and the total weight of the fruits and vegetables.

[0065] To make it easier to understand, the net weight of the fruits and vegetables inside the box can be calculated by pre-calibrating the weights of the first frame 14, the traction mechanism 30, and the empty box 20 when unloaded. Through this structure, the weighing sensor 40 does not directly participate in the transmission of traction force, but rather serves as part of the support structure, making its stress distribution more stable and reducing dynamic interference.

[0066] Please refer to the following: Figure 1 , Figure 3 and Figure 9In a second aspect, this application also provides a vertical packing machine 1000, including a fruit and vegetable conveyor belt 200 and a lifting box assembly 100 as described in the above embodiment. The fruit and vegetable conveyor belt 200 is used to transport fruits and vegetables. The box body 20 of the lifting box assembly 100 is located at the output end of the fruit and vegetable conveyor belt 200 and a fruit and vegetable container is disposed below it. The lifting box assembly 100 is used to receive fruits and vegetables on the fruit and vegetable conveyor belt 200 through the box body 20 and transfer the fruits and vegetables to the fruit and vegetable container below.

[0067] As is understood, the vertical boxing machine 1000 described in this application includes a fruit and vegetable conveyor belt 200 and a lifting box assembly 100. During operation, the fruit and vegetable conveyor belt 200 continuously or in batches transports the fruits and vegetables to be boxed to the lifting box assembly 100. The box body 20 of the lifting box assembly 100 is positioned at the output end of the fruit and vegetable conveyor belt 200 to receive these fruits and vegetables.

[0068] Meanwhile, fruit and vegetable containers are pre-placed below the lifting box assembly 100 or intermittently transported via a fruit and vegetable container conveyor belt. The lifting box assembly 100 receives the fruits and vegetables, weighs them in real time via the weighing sensor 40, and once the target weight is reached, the traction mechanism 30 controls the box body 20 to descend, transferring the weighed fruits and vegetables to the fruit and vegetable containers below. After unloading is complete, the box body 20 rises back to the receiving position.

[0069] The vertical boxing machine 1000 of this application embodiment, by integrating the lifting box assembly 100, realizes full automation or semi-automation of the entire process from fruit and vegetable conveying, receiving, real-time weighing to quantitative transfer and boxing, which significantly improves the accuracy and efficiency of boxing, ensures the consistency of the weight of each box of fruits and vegetables, and reduces manual operation and material waste.

[0070] In some embodiments, the vertical packing machine 1000 further includes a fruit and vegetable container conveyor belt disposed below the lifting box assembly 100 for transporting fruit and vegetable containers. The fruit and vegetable container conveyor belt includes a transport chain for transporting fruit and vegetable containers and a movable positioning mechanism. The positioning mechanism is capable of intermittently positioning each fruit and vegetable container on the transport chain belt below the box body 20 of the lifting box assembly 100, and allowing it to continue to be transported by the transport chain belt to the next process when the fruit and vegetables are transferred to the fruit and vegetable container.
