Description

Technical Field

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

[0002] In the automated operation of vertical fruit and vegetable packing machines, boxes with openings at the bottom are typically used to receive and unload fruits and vegetables. Flexible doors are used in vertical packing machines due to their gentle contact with fruits and vegetables and their structural adaptability.

[0003] However, existing technologies often struggle to achieve complex and precise coordinated movements when controlling the opening and closing of the bottom flexible door. The flexible door is prone to deformation as more fruits and vegetables are added, making it difficult to support them effectively. In some cases, the door may even create gaps between the door and the bottom of the container under pressure from the fruits and vegetables, causing them to detach from the container. Utility Model Content

[0004] One objective of this application is to provide a box assembly, a vertical boxing machine, and a fruit and vegetable sorting device to solve the technical problem that fruits and vegetables are prone to deformation and difficult to support properly when the amount of fruit and vegetables increases.

[0005] In a first aspect, embodiments of this application provide a housing assembly, including:

[0006] The box structure has an opening at the bottom;

[0007] A flexible door, comprising a first side and a second side opposite to each other;

[0008] The traction mechanism includes a drive module, a first traction member, and a second traction member. The first traction member is connected to a first side, and the second traction member is connected to a second side. The drive module is connected to both the first and second traction members. The first traction member is suspended below the opening by the drive module, and the second traction member is suspended on the outer periphery of the box structure by the drive module. The flexible door is supported and tensioned by the first traction member, the second traction member, and one side edge of the bottom of the box structure. The drive module is used to simultaneously drive the first traction member to move laterally along the opening and drive the second traction member to move up and down, so that the flexible door opens or closes the opening.

[0009] Wherein, the angle between the direction of the first side pointing to one side edge of the bottom of the box structure and the direction of the one side edge of the bottom of the box structure pointing to the second side is greater than 90°.

[0010] With the above structure, the embodiments of this application achieve precise control of the opening and closing of the flexible door by the joint support and tension of the first and second traction members and the bottom edge of the box structure, and by the coordinated control of the two traction members in a specific direction by the drive module. This helps to maintain the shape of the flexible door, reduce deformation and gaps under the pressure of fruits and vegetables, and thus better support the fruits and vegetables and prevent them from falling out of the gaps.

[0011] Optionally, the driving module includes:

[0012] A first rocker arm is hinged to the box structure, and one end of the rocker arm is connected to the first traction member;

[0013] The connecting frame is connected to the second traction component;

[0014] A first drive unit is installed on the box structure and connected to the connecting frame, and is used to drive the connecting frame to move up and down relative to the box structure to move up and down.

[0015] The first linkage unit is connected to the rocker arm and to the first drive unit or the connecting frame. When the first drive unit drives the connecting frame, it simultaneously drives the rocker arm to swing, causing the first traction member to move laterally along the opening, so that the flexible door opens or closes the opening.

[0016] With the above structure, the first linkage unit is connected between the first rocker arm and the first drive unit or connecting frame. When the first drive unit drives the connecting frame to rise and fall, the first linkage unit will simultaneously transmit this motion and convert it into the swing of the first rocker arm, thereby causing the first traction member to move laterally along the opening.

[0017] Optionally, the first drive unit includes a first drive component, which is mounted on the box structure and connected to the connecting frame. The first drive component can drive the connecting frame to move up and down relative to the box structure.

[0018] The first linkage unit includes a connecting rod, one end of which is hinged to the body of the first rocker arm, and the other end of which is hinged to the connecting frame. The connecting rod is used to drive the rocker arm to swing and move the first traction member laterally along the opening when the connecting frame moves up and down, so as to open or close the opening of the flexible door.

[0019] With the above structure, the first driving component directly drives the connecting frame to rise and fall. The first linkage unit is specifically a connecting rod, one end of which is hinged to the body of the first rocker arm, and the other end is hinged to the connecting frame. When the first driving component drives the connecting frame to rise and fall, the linear motion of the connecting frame is transmitted through the connecting rod, forcing the first rocker arm to swing around its hinge point, thereby driving the first traction component to move laterally.

[0020] Optionally, the first drive unit includes a second drive component, which is mounted on the box structure and connected to the connecting frame. The second drive component is capable of driving the connecting frame to move up and down relative to the box structure.

[0021] The first linkage unit includes a third driving component and a first controller. The third driving component is installed on the box structure and connected to the first rocker arm. The third driving component can drive the first rocker arm to swing. The first controller is connected to the second driving component and the third driving component respectively. The first controller is used to simultaneously control the second driving component and the third driving component, so that the first traction component and the second traction component are simultaneously pulled, so that the flexible door opens or closes the opening.

[0022] With the above structure, the first drive unit includes a second drive component for driving the connecting frame to raise and lower the second traction component. The first linkage unit includes an independent third drive component and a first controller. The third drive component directly drives the first rocker arm to swing, thereby controlling the lateral movement of the first traction component. The first controller is connected to and simultaneously controls the actions of the second and third drive components to ensure that the first and second traction components can move in coordination to realize the opening and closing of the flexible door.

[0023] Optionally, the third driving member is a telescopic driving member, which includes a first fixed part and a first movable part. The first fixed part is hinged to the box structure, and the first movable part is hinged to the first rocker arm and can move linearly relative to the first fixed part to drive the first rocker arm.

[0024] The third driving member is configured such that the direction in which the first fixed part points to the first movable part is inclined toward or horizontally toward the first rocker arm.

[0025] With the above structure, the third driving component is a telescopic driving component, such as an electric actuator or a cylinder. The third driving component includes a first fixed part hinged to the box structure and a first movable part hinged to the first rocker arm. The linear telescopic movement of the movable part relative to the fixed part drives the first rocker arm to swing. Its installation direction is configured such that the first fixed part is tilted or horizontally toward the first rocker arm in the direction pointing from the first movable part, ensuring that the telescopic driving component can effectively transmit force to the first rocker arm.

[0026] Optionally, the driving module includes:

[0027] The second rocker arm is hinged to the box structure, and one end of the second rocker arm is connected to the first traction member;

[0028] The second drive unit is installed in the box structure and connected to the second rocker arm, and is used to drive the second rocker arm to swing so that the first traction member moves laterally along the opening;

[0029] The second linkage unit includes a third traction member and a pull strap. The pull strap includes a third side and a fourth side opposite to each other. The third traction member is connected to the third side and the other end of the second rocker arm, and is suspended from the top of the box structure by the other end of the second rocker arm. The fourth side is connected to the second traction member. The pull strap is supported and tensioned by the second traction member, the third traction member, and one side edge of the top of the box structure. The second linkage unit is used to follow the other end of the second rocker arm and drive the second traction member to move when the second drive unit drives the second rocker arm to swing, so as to open or close the opening of the flexible door.

[0030] With the above structure, different components are driven by the two ends of the second rocker, and the motion is transmitted through the pull belt. The swing of the rocker is simultaneously converted into the lateral motion of the first traction component and the lifting motion of the second traction component, realizing the coordinated opening and closing of the flexible door controlled by a single drive source. The structure is relatively compact.

[0031] Optionally, the second drive unit includes a fourth drive member, which is a telescopic drive member. The fourth drive member includes a second fixed part and a second movable part. The second fixed part is hinged to the box structure, and the second movable part is hinged to the second rocker arm.

[0032] The fourth driving member is configured such that the direction in which the second fixed part points to the second movable part is inclined toward or horizontally toward the second rocker arm.

[0033] With the above structure, the second drive unit includes a fourth drive member, which comprises a second fixed part hinged to the box structure and a second movable part hinged to the second rocker arm. Its installation direction is also configured such that the second fixed part is tilted or horizontally toward the second rocker arm in the direction pointing towards the second movable part, to optimize the lever arm and stroke.

[0034] Optionally, the second rocker arm is provided with a hinge portion, and the second drive unit includes a slide rod and a slider. The slide rod is horizontally mounted on the box structure and parallel to the swing plane of the second rocker arm. The slider is connected to the slide rod, and the hinge portion is connected to the slider. When the slider is controlled to slide, it drives the hinge portion to make the second rocker arm swing.

[0035] With the above structure, the second rocker arm has a hinged portion. The second drive unit includes a slide bar horizontally mounted on the box structure and parallel to the swing plane of the second rocker arm, and a slider connected to the slide bar. The hinged portion of the second rocker arm is connected to the slider. When the slider is controlled to slide along the slide bar, it drives the second rocker arm to swing through the hinged portion.

[0036] In a second aspect, embodiments of this application also provide a vertical packing machine, comprising:

[0037] frame;

[0038] A fruit and vegetable conveyor belt, installed on the frame, is used to transport fruits and vegetables;

[0039] The box assembly as described in any of the above claims is vertically mounted on the frame and located at the output end of the fruit and vegetable conveyor belt, for receiving the fruit and vegetable conveyor belt, closing the opening during loading, and opening the opening during unloading.

[0040] In a third aspect, embodiments of this application also provide a fruit and vegetable sorting device, including the vertical packing machine as described above.

[0041] The embodiments of this application achieve the following technical effects: The flexible door is supported and tensioned by the first and second traction members and the bottom edge of the box structure. The drive module coordinates the movement of the two traction members in specific directions, achieving precise control over the opening and closing of the flexible door. This helps maintain the shape of the flexible door, reducing deformation and gaps under pressure from fruits and vegetables, thus better supporting the fruits and vegetables and preventing them from falling out of the gaps. Simultaneously, the included angle formed by the flexible door on one side of the bottom edge of the box structure exceeds 90°, reducing the frictional contact area between the flexible door and one side of the bottom edge of the box structure, avoiding obstruction during the movement of the flexible door 2.

[0053] 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.

[0054] 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.

[0055] In related technologies, vertical fruit and vegetable loading cameras often struggle to achieve complex and precise coordinated movements when controlling the opening and closing of the bottom flexible door. The flexible door is prone to deformation as more fruits and vegetables are added, making it difficult to properly support them. In some cases, the door may even create gaps between the fruit and vegetable loading camera and the bottom of the loading unit, causing the fruits and vegetables to detach from the loading unit through these gaps.

[0056] Please see Figures 1 to 3 To solve the above-mentioned technical problems, this application provides a box assembly 100, which is applied to a vertical box packer 1000 and can also be applied to other hoisting scenarios. For example, the vertical box packer 1000 includes a frame 200 and a fruit and vegetable conveyor belt 300. The fruit and vegetable conveyor belt 300 is mounted on the frame 200, and the box assembly 100 is liftably mounted on the frame 200 and located at the output end of the fruit and vegetable conveyor belt 300.

[0057] In some embodiments, the housing assembly 100 includes a housing structure 10, a flexible door 20, and a traction mechanism 30. The housing structure 10 has an opening 11 at its bottom. The flexible door 20 includes a first side 21 and a second side 22 opposite to each other. The traction mechanism 30 includes a drive module 31, a first traction member 32, and a second traction member 33. The first traction member 32 is connected to the first side 21, and the second traction member 33 is connected to the second side 22. The drive module 31 is connected to both the first traction member 32 and the second traction member 33. The first traction member 32 is suspended below the opening 11 by the drive module 31, and the second traction member 33 is suspended on the outer periphery of the housing structure 10 by the drive module 31. The flexible door 20 is supported and tensioned by the first traction member 32, the second traction member 33, and one side edge of the bottom of the housing structure 10. The drive module 31 is used to simultaneously drive the first traction member 32 to move laterally along the opening 11 and drive the second traction member 33 to move up and down, so that the flexible door 20 opens or closes the opening 11. The angle between the direction of the first side 21 pointing to one side edge of the bottom of the box structure 10 and the direction of the one side edge of the bottom of the box structure 10 pointing to the second side is greater than 90°.

[0058] The structural principle of the housing assembly 100 in this embodiment is as follows: The housing assembly 100 controls the coordinated movement of two traction members through the drive module 31 to realize the opening and closing of the flexible door 20. The first traction member 32 is connected to the first side 21 of the flexible door 20 and is suspended by the drive module 31 below the bottom opening 11 of the housing assembly 100, mainly responsible for the lateral expansion and contraction of the flexible door 20 below the opening 11. The second traction member 33 is connected to the second side 22 of the flexible door 20 and is suspended by the drive module 31 on the outer periphery of the housing structure 10, mainly responsible for the lifting and tensioning of the outer side of the flexible door 20. The flexible door 20 is supported and tensioned by the two traction members and one side edge of the bottom of the housing structure 10. The drive module 31 can simultaneously drive the first traction member 32 to move laterally along the opening 11 and drive the second traction member 33 to move up and down, thereby opening or closing the bottom opening 11 of the housing assembly 100. Furthermore, the angle α between the direction of the first side 21 pointing to one side edge of the bottom of the box structure 10 and the direction of the one side edge of the bottom of the box structure 10 pointing to the second side is set to exceed 90°, thereby reducing the frictional contact area between the flexible door 20 and one side edge of the bottom of the box structure 10.

[0059] Understandably, in this embodiment, the flexible door 20 is supported and tensioned by the first and second traction members 33 and the bottom edge of the box structure 10, and the drive module 31 coordinates the movement of the two traction members in a specific direction, thereby achieving precise control over the opening and closing of the flexible door 20. This helps maintain the shape of the flexible door 20, reduces deformation and gaps under the pressure of fruits and vegetables, and thus better supports the fruits and vegetables, preventing them from falling out of the gaps. At the same time, the included angle formed by the flexible door 20 on one side edge of the bottom of the box structure 10 exceeds 90°, in order to reduce the frictional contact area between the flexible door 20 and one side edge of the bottom of the box structure 10, and avoid obstruction when the flexible door 20 moves.

[0060] In some embodiments, both the first traction member 32 and the second traction member 33 are traction rollers, and the flexible door 20 can be a belt, textile belt, or chain plate, etc., and is wound around or fixed to the first traction member 32 and the second traction member 33. In other embodiments, the flexible door 20 can be a belt, textile belt, or chain plate, etc., and the flexible door 20 can be fastened to each of the first traction member 32 and the second traction member 33 by bolts and nuts, or by other fastening methods such as riveting.

[0061] In some embodiments, one side edge of the bottom of the box structure 10 may be provided with an arc surface or a support roller to prevent the bottom edge of the box structure 10 from pulling on the flexible door 20. Preferably, the included angle formed by the flexible door 20 at one side edge of the bottom of the box structure 10 is 120°.

[0062] Please see Figure 2 In some embodiments, the drive module 31 includes a first rocker arm 311, a connecting frame 312, a first drive unit 313, and a first linkage unit 314. The first rocker arm 311 is hinged to the box structure 10, and one end of the rocker arm is connected to the first traction member 32. The connecting frame 312 is connected to the second traction member 33. The first drive unit 313 is mounted on the box structure 10 and connected to the connecting frame 312, and is used to drive the connecting frame 312 to move up and down, thereby causing the second traction member 33 to move up and down relative to the box structure 10. The first linkage unit 314 is connected to the first rocker arm 311 and to the first drive unit 313 or the connecting frame 312, and is used to drive the rocker arm to swing while the first drive unit 313 drives the connecting frame 312, thereby causing the first traction member 32 to move laterally along the opening 11, so that the flexible door 20 opens or closes the opening 11.

[0063] Understandably, the first linkage unit 314 is connected between the first rocker arm 311 and the first drive unit 313 or the connecting frame 312. When the first drive unit 313 drives the connecting frame 312 to rise or fall, the first linkage unit 314 simultaneously transmits this motion and converts it into the swinging motion of the first rocker arm 311, thereby causing the first traction member 32 to move laterally along the opening 11. In this way, the linkage of the two traction members is achieved through a single drive source, improving the reliability and coordination of the system, and reducing the difficulty of achieving complex coordinated actions.

[0064] In some embodiments, the first rocker arms 311 are arranged in pairs, with the two first rocker arms 311 of the same pair located on opposite sides of the box structure 10 and connected to the same first linkage unit 314. The two first rocker arms 311 of the same pair are respectively connected to the first traction member 32.

[0065] Please see Figure 3 In some embodiments, the first drive unit 313 includes a first drive member 3131, which is mounted on the box structure 10 and connected to the connecting frame 312. The first drive member 3131 can drive the connecting frame 312 to move up and down relative to the box structure 10. The first linkage unit 314 includes a connecting rod 3141, one end of which is hinged to the body of the first rocker arm 311, and the other end of which is hinged to the connecting frame 312. The connecting rod 3141 is used to drive the rocker arm to swing while the connecting frame 312 moves up and down, so that the first traction member 32 moves laterally along the opening 11, thereby opening or closing the flexible door 20.

[0066] Understandably, the first driving component 3131 directly drives the connecting frame 312 to rise and fall. The first linkage unit 314 is specifically a connecting rod 3141, one end of which is hinged to the body of the first rocker arm 311, and the other end is hinged to the connecting frame 312. When the first driving component 3131 drives the connecting frame 312 to rise and fall, the linear motion of the connecting frame 312 is transmitted through the connecting rod 3141, forcing the first rocker arm 311 to swing around its hinge point, thereby driving the first traction component 32 to move laterally. This embodiment of the application realizes the conversion from lifting motion to swinging motion through the connecting rod 3141 mechanism, which is simple in structure, highly reliable, low in cost, and easy to implement and maintain. In this embodiment, the first driving component 3131 is a cylinder; in other embodiments, the first driving component 3131 can be an electric push rod or an electric cylinder, etc.

[0067] For example, the first driving component 3131 is a linear push rod cylinder, the cylinder body of which is mounted on the housing structure 10, and the piston of which is connected to the connecting frame 312. The designer can set the number and position of the first driving components 3131 according to experience and actual needs. For example, there can be two first driving components 3131, spaced apart and connected to the same connecting frame 312, to smoothly drive the connecting frame 312 to move up and down.

[0068] In some embodiments, the first drive unit 3131 is connected to and controlled by the controller of the vertical packing machine 1000. This controller may be a programmable logic controller (PLC) or a microcontroller (MCU), etc. When the first drive unit 3131 is a cylinder, the controller connects to the cylinder's valve and controls the opening and closing of the valve to control the cylinder. When the first drive unit 3131 is an electric actuator or electric cylinder, the controller can control corresponding electronic components, such as the motors of each electric actuator, to drive the electric actuator or electric cylinder. In other embodiments, the cylinder's valve may be equipped with a corresponding manual switch to allow the operator to manually control the cylinder; correspondingly, the motor of the electric actuator may be equipped with a corresponding power switch to allow the operator to manually turn the electric actuator on or off.

[0069] In some embodiments, the first rocker arms 311 are arranged in pairs, with the two first rocker arms 311 of the same pair located on opposite sides of the box structure 10. The connecting rods 3141 are also arranged in pairs, with the two connecting rods 3141 of the same pair located on opposite sides of the box structure 10. Each connecting rod 3141 is connected to the same connecting frame 312, and each connecting rod 3141 is also connected to a corresponding first rocker arm 311. When the connecting frame 312 is raised or lowered, each connecting rod 3141 synchronously drives the corresponding first rocker arm 311, so that the paired first rocker arms 311 jointly drive the first traction member 32.

[0070] Please refer to the following: Figures 4 to 6In some embodiments, the first drive unit 313 includes a second drive member 3132, which is mounted on the box structure 10 and connected to the connecting frame 312. The second drive member 3132 can drive the connecting frame 312 to move up and down relative to the box structure 10. The first linkage unit 314 includes a third drive member 3142 and a first controller 3143. The third drive member 3142 is mounted on the box structure 10 and connected to the first rocker arm 311. The third drive member 3142 can drive the first rocker arm 311 to swing. The first controller 3143 is connected to both the second drive member 3132 and the third drive member 3142. The first controller 3143 is used to simultaneously control the second drive member 3132 and the third drive member 3142, so that the first traction member 32 and the second traction member 33 are simultaneously pulled, so that the flexible door 20 opens or closes the opening 11.

[0071] Understandably, the first drive unit 313 includes a second drive member 3132 for driving the connecting frame 312 to raise and lower the second traction member 33. The first linkage unit 314 includes an independent third drive member 3142 and a first controller 3143. The third drive member 3142 directly drives the first rocker arm 311 to swing, thereby controlling the lateral movement of the first traction member 32. The first controller 3143 is connected to and simultaneously controls the actions of the second drive member 3132 and the third drive member 3142 to ensure that the first traction member 32 and the second traction member 33 can move in coordination to realize the opening and closing of the flexible door 20. The embodiments of this application adopt dual drive and electronic control synchronization, which has higher control accuracy and flexibility, and can more easily adjust the movement amplitude and speed relationship of the two traction members to adapt to different working conditions. In this embodiment, the second drive member 3132 and the third drive member 3142 are both cylinders. In other embodiments, either the second drive member 3132 or the third drive member 3142 can be an electric push rod or an electric cylinder, etc.

[0072] For example, the second driving element 3132 is a linear push rod cylinder, the cylinder body of which is mounted on the housing structure 10, and the piston of the cylinder is connected to the connecting frame 312. The designer can set the number and position of the second driving element 3132 according to experience and actual needs. For example, there can be two second driving elements 3132, with two first driving elements 3131 spaced apart and connected to the same connecting frame 312, to smoothly drive the connecting frame 312 to move up and down.

[0073] In some embodiments, the first controller 3143 may be a programmable logic controller (PLC) or a microcontroller (MCU), etc., and may be part of the control system of the vertical packing machine 1000, or may be a controller configured separately for the housing assembly 100. When the second drive unit 3132 and the third drive unit 3142 are cylinders, the first controller 3143 connects to the air valves of each cylinder and controls the opening and closing of the air valves to control each cylinder; when the second drive unit 3132 and the third drive unit 3142 are electric drive units such as electric push rods or electric cylinders, the first controller 3143 can control the corresponding electronic control components, such as the motors of each electric drive unit, to drive the electric push rods or electric cylinders, etc.

[0074] In some embodiments, the third driving member 3142 is a telescopic driving member, comprising a first fixed portion 31421 and a first movable portion 31422. The first fixed portion 31421 is hinged to the box structure 10, and the first movable portion 31422 is hinged to the first rocker arm 311 and is capable of linear movement relative to the first fixed portion 31421 to drive the first rocker arm 311. The third driving member 3142 is configured such that the direction from the first fixed portion 31421 to the first movable portion 31422 is either inclined towards or horizontally towards the first rocker arm 311. For example... Figure 4 The first fixing part 31421 of the third drive member 3142 of the housing assembly 100 is tilted downward toward the first rocker arm 311, pointing in the direction of the first movable part 31422. Figure 6 The first fixed part 31421 of the third drive member 3142 of the middle housing assembly 100 is tilted upward toward the first rocker arm 311 in the direction of the first movable part 31422.

[0075] Understandably, the third drive component 3142 is a telescopic drive component, such as an electric actuator or cylinder. The third drive component 3142 includes a first fixed portion 31421 hinged to the housing structure 10 and a first movable portion 31422 hinged to the first rocker arm 311. The linear telescopic movement of the first movable portion 31422 relative to the first fixed portion 31421 drives the first rocker arm 311 to swing. Its installation direction is set such that the direction from the first fixed portion 31421 to the first movable portion 31422 is either inclined towards or horizontally towards the first rocker arm 311, ensuring that the telescopic drive component can effectively transmit force to the first rocker arm 311.

[0076] For example, the third driving member 3142 is a linear push rod cylinder, the first fixed part 31421 is a part of the cylinder body structure, such as the end of the cylinder body structure, and the first movable part 31422 is a part of the piston rod structure of the cylinder, such as the piston rod joint. The designer can set the number and position of the third driving member 3142 according to experience and actual needs. For example, there can be two third driving members 3142, each connected to a corresponding first rocker arm 311 to drive the corresponding first rocker arm 311 to swing. The two third driving members 3142 are configured to drive synchronously so that different first rocker arms 311 synchronously drive the same first traction member 32 to move laterally along the opening 11 of the box structure 10.

[0077] In other embodiments, the third drive member 3142 is a swing drive member, such as a swing cylinder, to realize the swing drive of the first rocker arm 311. The specific configuration of the swing drive member can be referred to the relevant technology, and is not limited here.

[0078] Please see Figure 7 In some embodiments, the drive module 31 includes a second rocker arm 315, a second drive unit 316, and a second linkage unit 317. The second rocker arm 315 is hinged to the box structure 10, and one end of the second rocker arm 315 is connected to the first traction member 32. The second drive unit 316 is mounted on the box structure 10 and connected to the second rocker arm 315, and is used to drive the second rocker arm 315 to swing, thereby causing the first traction member 32 to move laterally along the opening 11.

[0079] The second linkage unit 317 includes a third traction member 3171 and a pull strap 3172. The pull strap 3172 includes a third side 31721 and a fourth side 31722 opposite to each other. The third traction member 3171 is connected to the third side 31721 and the other end of the second rocker arm 315 respectively, and is suspended on the top of the box structure 10 by the other end of the second rocker arm 315. The fourth side 31722 is connected to the second traction member 33. The pull strap 3172 is supported and tensioned by the second traction member 33, the third traction member 3171 and one side edge of the top of the box structure 10. The second linkage unit 317 is used to follow the other end of the second rocker arm 315 and drive the second traction member 33 to move when the second drive unit 316 drives the second rocker arm 315 to swing, so as to open or close the opening 11 of the flexible door 20.

[0080] Understandably, the second drive unit 316 drives the second rocker arm 315 to swing, thereby causing the first traction member 32 to move laterally along the opening 11. The second linkage unit 317 is responsible for the movement of the second traction member 33, which includes a third traction member 3171 and a pull strap 3172. The third traction member 3171 is connected to the third side 31721 of the pull strap 3172 and the other end of the second rocker arm 315, and is suspended by this end from the top of the box structure 10. The fourth side 31722 of the pull strap 3172 is connected to the second traction member 33. The pull strap 3172 is supported and tensioned by the second traction member 33, the third traction member 3171, and one side edge of the top of the box structure 10. When the second drive unit 316 drives the second rocker arm 315 to swing, one end of the rocker arm drives the first traction member 32; at the same time, the other end of the second rocker arm 315 drives the third traction member 3171 to move, and the third traction member 3171 pulls the second traction member 33 up and down through the pull strap 3172.

[0081] In this embodiment, the two ends of the second rocker 315 drive different components respectively, and the motion is transmitted through the pull belt 3172. The swing of the rocker is simultaneously converted into the lateral motion of the first traction member 32 and the lifting motion of the second traction member 33, realizing the coordinated opening and closing of the flexible door 20 controlled by a single drive source. The structure is relatively compact.

[0082] In some embodiments, one side edge of the top of the box structure 10 may be provided with an arc surface or a support roller to prevent the top edge of the box structure 10 from pulling the strap 3172.

[0083] In some embodiments, the second linkage unit 317 further includes a fourth traction member and a connecting member. The fourth side 31722 of the pull strap 3172 is connected to the fourth traction member, and the connecting member is connected to the fourth traction member and the second traction member 33 respectively, so that the second linkage unit 317 pulls the second traction member 33 to rise and fall sequentially through the force transmission path of the third traction member 3171, the pull strap 3172, the fourth traction member, the connecting member, and the second traction member 33. The connecting member can be a common rigid structural component, or it can be a tensioning mechanism of the tensioning pull strap 3172 and the flexible door 20.

[0084] In some embodiments, the third traction member 3171 and the fourth traction member are both traction rollers, and the pull belt 3172 can be a belt, textile belt, or chain plate, etc., and the pull belt 3172 is wound around or fixed to the third traction member 3171 and the fourth traction member. In other embodiments, the pull belt 3172 can be a belt, textile belt, or chain plate, etc., and the pull belt 3172 can be fastened to the third traction member 3171 and the fourth traction member by bolts and nuts, or by other fastening methods such as riveting.

[0085] In some embodiments, the second drive unit 316 includes a fourth drive member 3161, which is a telescopic drive member. The fourth drive member 3161 includes a second fixed portion 31611 and a second movable portion 31612. The second fixed portion 31611 is hinged to the box structure 10, and the second movable portion 31612 is hinged to the second rocker arm 315. The fourth drive member 3161 is configured such that the direction from the second fixed portion 31611 to the second movable portion 31612 is either inclined towards or horizontally towards the second rocker arm 315. For example... Figure 7 The second fixed part 31611 of the third drive member 3142 of the housing assembly 100 is generally horizontally oriented toward the second rocker arm 315, pointing toward the second movable part 31612.

[0086] Understandably, the second drive unit 316 includes a fourth drive member 3161, which is a telescopic drive member. The fourth drive member 3161 includes a second fixed part 31611 hinged to the housing structure 10 and a second movable part 31612 hinged to the second rocker arm 315. Its installation direction is also set such that the direction from the second fixed part 31611 to the second movable part 31612 is either inclined towards or horizontally towards the second rocker arm 315, to optimize the lever arm and stroke.

[0087] In some embodiments, the fourth drive unit 3161 is connected to and controlled by the controller of the vertical packing machine 1000. This controller may be a programmable logic controller (PLC) or a microcontroller (MCU). When the fourth drive unit 3161 is a cylinder, the controller connects to the cylinder's valve and controls the opening and closing of the valve to control the cylinder. When the fourth drive unit 3161 is an electric actuator or electric cylinder, the controller can control corresponding electronic components, such as the motors of each electric actuator, to drive the electric actuator or electric cylinder. In other embodiments, the cylinder's valve may be equipped with a corresponding manual switch to allow the operator to manually control the cylinder; correspondingly, the motor of the electric actuator may be equipped with a corresponding power switch to allow the operator to manually turn the motor on or off.

[0088] For example, the fourth drive member 3161 is a linear push rod cylinder, the second fixed part 31611 is a part of the cylinder body structure, such as the end of the cylinder body structure, and the second movable part 31612 is a part of the piston rod structure of the cylinder, such as the piston rod joint.

[0089] In other embodiments, the fourth drive member 3161 is a swing drive member, such as a swing cylinder, to drive the swing of the second rocker arm 315. The specific configuration of the swing drive member can be referred to in related technologies, and is not limited here.

[0090] Please see Figure 8 In some embodiments, the second rocker arm 315 is provided with a hinge portion 3151, and the second drive unit 316 includes a slide rod 3162 and a slider 3163. The slide rod 3162 is horizontally mounted on the box structure 10 and parallel to the swing plane of the second rocker arm 315. The slider 3163 is connected to the slide rod 3162. The hinge portion 3151 is connected to the slider 3163. When the slider 3163 is controlled to slide, it drives the hinge portion 3151 to make the second rocker arm 315 swing.

[0091] Understandably, the second rocker arm 315 is provided with a hinge portion 3151. The second drive unit 316 includes a slide bar 3162 horizontally mounted on the box structure 10 and parallel to the swing plane of the second rocker arm 315, and a slider 3163 connected to the slide bar 3162. The hinge portion 3151 of the second rocker arm 315 is connected to the slider 3163. When the slider 3163 is controlled to slide along the slide bar 3162, the second rocker arm 315 is driven to swing through the hinge portion 3151. In this embodiment, the rocker arm is driven by a slide bar 3162 and slider 3163 mechanism, which can accurately convert linear sliding motion into the swing motion of the rocker arm.

[0092] For example, the second drive unit 316 is installed inside the box structure 10, and the second rocker arm 315 is located outside the box structure 10. The box structure 10 is provided with a clearance hole 12 to avoid the hinge portion 3151 of the second rocker arm 315, so that the hinge portion 3151 of the second rocker arm 315 can pass through the clearance hole 12 and connect to the slider 3163. For another example, the slider 3163 is provided with an oblong hole 31631 extending in the height direction. The hinge portion 3151 is a cylindrical structure, which is received in the oblong hole 31631 and cooperates with the oblong hole 31631. When the slider 3163 moves in a controlled manner, it abuts against the hinge portion 3151 laterally through the inner wall of the oblong hole 31631, causing the second rocker arm 315 to swing. At the same time, the hinge portion 3151 can move in the height direction of the oblong hole 31631, thereby avoiding interference.

[0093] In some embodiments, the second drive unit 316 is connected to and controlled by the controller of the vertical packing machine 1000. This controller may be a programmable logic controller (PLC) or a microcontroller (MCU). When the second drive unit 316 is a cylinder, such as a rodless cylinder, the controller connects to the cylinder's valve and controls its opening and closing to control the slider 3163. When the second drive unit 316 is an electric drive component such as an electric lead screw slider 3163 module, the controller can control corresponding electrical components, such as the motors of each electric drive component, to drive the slider 3163. In other embodiments, the cylinder's valve may be equipped with a corresponding manual switch to allow the operator to manually control the cylinder; correspondingly, the motor of the electric drive component may be equipped with a corresponding power switch to allow the operator to manually turn the electric drive component on or off.
