Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a fruit box positioning mechanism and a fruit and vegetable sorting device. Background Technology

[0002] Currently, fruits and vegetables are a type of food that people often consume. Fruits and vegetables include citrus fruits, cherries, apples, pears, and tomatoes. After ripening, fruits and vegetables need to be harvested and then transported to factories for sorting and processing to facilitate subsequent packaging and sales.

[0003] In related technologies, fruit and vegetable sorting devices can collect information about fruits and vegetables and sort them according to that information. After the fruit and vegetable sorting device completes the sorting, fruits and vegetables of the same grade can be transported to the same output channel. Users need to pack the fruits and vegetables at the same output channel into boxes, and the packed fruits and vegetables can be transported to the sales outlet for sale.

[0004] However, during the fruit and vegetable packing process, users generally need to place the fruit box under the fruit and vegetable grabbing mechanism so that the grabbing mechanism can accurately fill the fruit and vegetables into the fruit box; this results in a low degree of automation in fruit and vegetable packing and a slow packing efficiency. Utility Model Content

[0005] The present invention aims to provide a fruit box positioning mechanism and a fruit and vegetable sorting device to solve the technical problems of low automation and slow efficiency in the prior art of fruit and vegetable boxing.

[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution:

[0007] A fruit box positioning mechanism is provided, comprising:

[0008] frame;

[0009] A lifting assembly having a receiving cavity for receiving a fruit box, the lifting assembly being mounted on the frame;

[0010] A drive assembly, mounted on the frame, is used to drive the lifting assembly to move vertically relative to the frame;

[0011] A fruit box fixing assembly is installed on the frame and is located above the lifting assembly. During the process of the driving assembly driving the lifting assembly to rise, the fruit box fixing assembly can extend into the fruit box located in the receiving cavity and abut against the inner side wall of the fruit box.

[0012] With the above structure, the mechanism for conveying the fruit box can transport the fruit box into the receiving cavity. The drive component can drive the lifting component to rise relative to the frame. During the rising process, the lifting component can drive the fruit box fixing component into the opening of the fruit box. When the fruit box fixing component is located at the opening of the fruit box, it can abut against the inner wall of the fruit box, so that the opening of the fruit box is opened and the fruit box is fixed. After the fruit box is fixed, the fruit and vegetable grabbing mechanism can quickly load the fruit and vegetables into the fruit box.

[0013] Once the fruit box is full, the drive unit can drive the lifting unit to descend relative to the frame. During the descent, the lifting unit can bring the fruit box back to its initial position. Then, the mechanism for conveying the fruit box can bring a new empty fruit box into the receiving cavity and squeeze the fruit box filled with fruits and vegetables out of the receiving cavity, thereby improving the automation level of the fruit and vegetable packing process and increasing the packing speed.

[0014] In some embodiments, the fruit box positioning mechanism further includes:

[0015] Multiple roller components are arranged below the frame. The roller components are rotatably connected to the frame. The arrangement direction of the roller components is perpendicular to the extension direction of the rotation axis of the roller components. There is a gap between two adjacent roller components.

[0016] The lifting assembly includes multiple bottom support bars arranged in parallel, which are used to support the bottom of the fruit box; during the process of the driving assembly driving the lifting assembly to rise or fall, each bottom support bar can pass through the gap between two adjacent rollers.

[0017] With the above structure, during the process of the fruit box conveying mechanism pushing the fruit box into the receiving cavity, the bottom support bar can be located below the roller component, and the bottom of the fruit box contacts the roller component, making it easier for the fruit box to enter the receiving cavity. During the process of the drive assembly driving the lifting assembly to rise relative to the frame, the bottom support bar can pass through the gap between two adjacent roller components, and the bottom support bar contacts and drives the fruit box to move upward.

[0018] After the fruit box is filled with fruits and vegetables, the drive component drives the lifting component to descend relative to the frame. During this process, the bottom support bar can pass through the gap between two adjacent roller components. When the fruit box contacts the roller component again, the fruit box filled with fruits and vegetables is heavier, and when a new empty fruit box enters the receiving cavity, it is easier to push the fruit box filled with fruits and vegetables on the roller component to move out of the receiving cavity.

[0019] In some embodiments, the lifting assembly further includes a mounting frame and a rotation limiting component, the bottom support bar is mounted on the lower end of the mounting frame, the mounting frame is mounted on the frame, and the drive assembly is used to drive the mounting frame to move vertically relative to the frame;

[0020] The rotation limiting component is rotatably connected to the mounting frame, the rotation axis of the rotation limiting component is located on one side of the mounting frame, and the rotation axis of the rotation limiting component is perpendicular to the rotation axis of the roller component; the receiving cavity is opened in the mounting frame, the outlet of the receiving cavity is located on one side of the mounting frame, and the rotation limiting component is used to open or close the outlet of the receiving cavity.

[0021] With the above structure, after the mechanism for conveying the fruit box pushes the empty fruit box into the receiving cavity, the rotating limiting component can close the outlet of the receiving cavity. The rotating limiting component can abut against one side of the empty fruit box to prevent the fruit box from being misaligned with the fruit box fixing component during the process of the lifting component rising relative to the frame.

[0022] In addition, when the fruit box filled with fruits and vegetables descends onto the roller component, the rotating limiting component can open the outlet of the receiving cavity, so that a new empty fruit box can enter the receiving cavity and push the fruit box filled with fruits and vegetables out of the receiving cavity.

[0023] In some embodiments, the rotation limiting component includes a first rotation driving member and a rotation rod. The first rotation driving member is mounted on one side of the mounting bracket and is used to drive the rotation rod to rotate. The rotation axis of the rotation rod is perpendicular to the rotation axis of the roller component.

[0024] The first rotation drive unit drives the rotating rod to rotate to a position parallel to the horizontal plane to close the outlet of the receiving cavity; the first rotation drive unit drives the rotating rod to rotate to a position perpendicular to the horizontal plane to open the outlet of the receiving cavity.

[0025] With the above structure, the first rotation drive can drive the rotating rod to rotate; when the first rotation drive drives the rotating rod to a position parallel to the horizontal plane, one side of the fruit box abuts against the rotating rod, so the fruit box will not move out of the receiving cavity, that is, the outlet of the receiving cavity is closed; when the first rotation drive drives the rotating rod to a position perpendicular to the horizontal plane, the rotating rod is located on one side of the mounting frame, so the fruit box can move out of the receiving cavity, that is, the outlet of the receiving cavity is opened.

[0026] In some embodiments, the drive assembly includes a drive component, a chain component, and a sprocket component. The drive component is mounted below the frame, the sprocket component is rotatably connected to the frame, the chain component is sleeved on the sprocket component, and the lifting assembly is fixed to the chain component. The drive component is used to drive the sprocket component to rotate, thereby moving the chain component and causing the lifting assembly to move vertically relative to the frame.

[0027] With the above structure, the drive component drives the lifting assembly to move vertically relative to the frame through the sprocket component and the chain component, so that the lifting assembly is more stable during the rising or falling process, so as to prevent the fruits and vegetables in the fruit box from falling out of the fruit box due to shaking.

[0028] In some embodiments, the fruit box fixing assembly includes a positioning component and three rotating and spreading components, which are respectively located at the four sides of the opening of the fruit box;

[0029] The positioning component is mounted on the frame, and the rotating expansion component is rotatably connected to the frame. During the process of the driving component driving the lifting component to rise, the positioning component and the three rotating expansion components can extend into the fruit box located in the receiving cavity. The positioning component abuts against one inner wall of the fruit box, and the rotating expansion component can rotate and abut against the corresponding inner wall of the fruit box.

[0030] With the above structure, during the process of the lifting assembly driving the fruit box to rise, the positioning component and the three rotating support components can simultaneously extend into the opening of the fruit box. The positioning component abuts against one of the inner side walls of the fruit box, and the rotating support components rotate relative to the frame. Each rotating support component can abut against the inner side wall of a corresponding fruit box, thereby the fruit box fixing component plays a role in fixing the fruit box.

[0031] In some embodiments, the number of fruit box fixing components is two, and the positioning component includes guide ramps, the upper ends of the two guide ramps being connected to each other; in the top-to-bottom direction, each guide ramp is inclined away from the other guide ramp.

[0032] With the above structure, two fruit box fixing components are used, allowing the fruit box positioning mechanism to simultaneously position two fruit boxes. This enables both fruit boxes to be filled with fruits and vegetables at the same time, further improving the packing efficiency. From top to bottom, each guide wall is inclined away from the other, so that as the fruit box fixing components extend into the fruit box, the guide walls guide the fruit box, further reducing the possibility of the fruit box and the fixing components misaligning.

[0033] In some embodiments, the fruit box fixing assembly further includes a box pressing bracket and a vertical drive component. The vertical drive component is mounted on the frame and is used to drive the box pressing bracket to move vertically relative to the frame. The upper ends of the two guide inclined walls are respectively connected to the opposite sides of the box pressing bracket. During the process of the vertical drive component driving the box pressing bracket to move downward, the box pressing bracket can abut against the upper end of the side wall of the fruit box.

[0034] With the above structure, as the driving component drives the lifting component to move upward, the guide inclined wall extends into the corresponding fruit box, and the vertical driving component drives the pressing bracket to move downward, so that the pressing bracket can abut against the upper end of the side wall of the fruit box. The pressing bracket and the lifting component together clamp the fruit box, so that the fruit box can be more stable during the fruit and vegetable packing process.

[0035] In some embodiments, the rotating expansion component includes a second rotating drive member and a limiting plate. The limiting plate is rotatably connected to the frame. The second rotating drive member is used to drive the limiting plate to rotate relative to the frame, so that the limiting plate can abut against a corresponding inner sidewall of the fruit box.

[0036] With the above structure, before the fruit box fixing assembly extends into the fruit box, the limiting plate can be tilted relative to the horizontal plane, so that the limiting plate can be more easily inserted into the opening of the fruit box; after the limiting plate extends into the fruit box, the second rotation drive can drive the limiting plate to rotate to a position perpendicular to the horizontal plane, and the limiting plate can abut against one of the inner side walls of the fruit box.

[0037] Another embodiment of this utility model provides a fruit and vegetable sorting device, including the fruit and vegetable positioning mechanism in any of the above embodiments.

[0038] Compared with existing technologies, the mechanism for conveying fruit boxes can transport the fruit boxes into the receiving cavity. The drive component can drive the lifting component to rise relative to the frame. During the rising process, the lifting component can drive the fruit box fixing component into the opening of the fruit box. When the fruit box fixing component is located at the opening of the fruit box, it can abut against the inner wall of the fruit box, so that the opening of the fruit box is opened and the fruit box is fixed. After the fruit box is fixed, the fruit and vegetable grabbing mechanism can quickly load the fruits and vegetables into the fruit box.

[0039] Once the fruit box is full, the drive unit can drive the lifting unit to descend relative to the frame. During the descent, the lifting unit can bring the fruit box back to its initial position. Then, the mechanism for conveying the fruit box can bring a new empty fruit box into the receiving cavity and squeeze the fruit box filled with fruits and vegetables out of the receiving cavity, thereby improving the automation level of the fruit and vegetable packing process and increasing the packing speed.

[0052] The following detailed description, in conjunction with all the accompanying drawings, of a fruit box positioning mechanism 100 and a fruit and vegetable sorting device provided in this application, will be provided through specific embodiments.

[0053] Please refer to Figure 1 and Figure 2 One embodiment of this utility model discloses a fruit box positioning mechanism 100, including a frame 10, a lifting assembly 20, a driving assembly 30, and a fruit box fixing assembly 40; the lifting assembly 20 has a receiving cavity 202 for receiving fruit boxes, and the lifting assembly 20 is mounted on the frame 10; the driving assembly 30 is mounted on the frame 10 and is used to drive the lifting assembly 20 to move vertically relative to the frame 10; the fruit box fixing assembly 40 is mounted on the frame 10 and is located above the lifting assembly 20; during the process of the driving assembly 30 driving the lifting assembly 20 to rise, the fruit box fixing assembly 40 can extend into the fruit box located in the receiving cavity 202 and abut against the inner side wall of the fruit box.

[0054] With the above structure, the mechanism for conveying the fruit box can transport the fruit box into the receiving cavity 202. The drive component 30 can drive the lifting component 20 to rise relative to the frame 10. During the rising process, the lifting component 20 can drive the fruit box fixing component 40 into the opening of the fruit box. When the fruit box fixing component 40 is located at the opening of the fruit box, the fruit box fixing component 40 can abut against the inner side wall of the fruit box, so that the opening of the fruit box is opened and the fruit box is fixed. After the fruit box is fixed, the fruit and vegetable grabbing mechanism can quickly load the fruit and vegetables into the fruit box.

[0055] After the fruit box is full of fruits and vegetables, the drive component 30 can drive the lifting component 20 to descend relative to the frame 10. During the descent of the lifting component 20, the fruit box can be driven back to the initial position. Then, the mechanism for conveying the fruit box can drive a new empty fruit box into the receiving cavity 202 and squeeze the fruit box containing fruits and vegetables out of the receiving cavity 202, so as to improve the automation level of the fruit and vegetable packing process and increase the packing speed of fruits and vegetables.

[0056] Specifically, in this embodiment, the frame 10 may include steel plates and steel bars spliced ​​together, and the frame 10 may have a frame structure similar to a cuboid; the lifting assembly 20 may also include steel plates and steel bars spliced ​​together, and the receiving cavity 202 is formed between the steel plates and steel bars of the lifting assembly 20. Openings may be provided on opposite sides of the receiving cavity 202. The opening on one side of the receiving cavity 202 is used for the fruit box to enter, and the opening on the other opposite side is used for the fruit box to move out.

[0057] The drive assembly 30 may include a chain structure driven by an electric motor. One side of the lifting assembly 20 may be fixed to the chain of the drive assembly 30. The electric motor can drive the lifting assembly 20 to move vertically relative to the frame 10 via the chain. The fruit box fixing assembly 40 may include multiple plate-like structures, each of which can abut against a corresponding inner sidewall of the fruit box, so that the fruit box fixing assembly 40 can fix the fruit box.

[0058] In other embodiments, the frame 10 may also include other structures, such as a hollow box structure; the lifting assembly 20 may also include other structures, such as a box structure with openings on opposite sides; the drive assembly 30 may also include other structures, such as a pulley structure driven by an electric motor; the fruit box fixing assembly 40 may also include other structures, such as multiple strip structures for abutting against the inner sidewall of the fruit box.

[0059] Please refer to Figure 3 L1 is the conveying direction of fruits and vegetables. In some embodiments, the fruit box positioning mechanism 100 also includes a plurality of rollers 50. All rollers 50 are arranged below the frame 10. The rollers 50 are rotatably connected to the frame 10. The arrangement direction of the rollers 50 is perpendicular to the extension direction of the rotation axis of the rollers 50. There is a gap between two adjacent rollers 50. The lifting assembly 20 includes a plurality of bottom support bars 22 arranged in parallel. The bottom support bars 22 are used to support the bottom of the fruit box. During the process of the driving assembly 30 driving the lifting assembly 20 to rise or fall, each bottom support bar 22 can pass through the gap between two adjacent rollers 50.

[0060] With the above structure, during the process of the fruit box being pushed into the receiving cavity 202 by the mechanism for conveying the fruit box, the bottom support bar 22 can be located below the roller component, and the bottom of the fruit box contacts the roller component 50, making it easier for the fruit box to enter the receiving cavity 202. During the process of the drive assembly 30 driving the lifting assembly 20 to rise relative to the frame 10, the bottom support bar 22 can pass through the gap between two adjacent roller components 50, and the bottom support bar 22 contacts and drives the fruit box to move upward.

[0061] After the fruit box is filled with fruits and vegetables, as the drive assembly 30 drives the lifting assembly 20 to descend relative to the frame 10, the bottom support bar 22 can pass through the gap between two adjacent rollers 50. The fruit box contacts the roller 50 again. The fruit box filled with fruits and vegetables is relatively heavy, and when the new empty fruit box enters the receiving cavity 202, it is easier to push the fruit box filled with fruits and vegetables on the roller 50 out of the receiving cavity 202.

[0062] Specifically, in this embodiment, the roller component 50 can be rotatably connected to the frame 10 via a rotating shaft, the bottom support bar 22 can be made of steel, and a roller component 50 can be provided on two adjacent bottom support bars 22.

[0063] In other embodiments, adjacent bottom support bars 22 may also be provided with other numbers of rollers 50, such as two or three.

[0064] In some embodiments, the lifting assembly 20 further includes a mounting frame 24 and a rotation limiting component 26. A bottom support bar 22 is installed at the lower end of the mounting frame 24, which is mounted on the frame 10. The drive assembly 30 is used to drive the mounting frame 24 to move vertically relative to the frame 10. The rotation limiting component 26 is rotatably connected to the mounting frame 24, and the rotation axis of the rotation limiting component 26 is located on one side of the mounting frame 24. The rotation axis of the rotation limiting component 26 is perpendicular to the rotation axis of the roller component 50. A receiving cavity 202 is opened in the mounting frame 24, and the outlet of the receiving cavity 202 is located on one side of the mounting frame 24. The rotation limiting component 26 is used to open or close the outlet of the receiving cavity 202.

[0065] With the above structure, after the mechanism for conveying the fruit box pushes the empty fruit box into the receiving cavity 202, the rotating limiting component 26 can close the outlet of the receiving cavity 202. The rotating limiting component 26 can abut against one side of the empty fruit box to prevent the fruit box and the fruit box fixing component 40 from being misaligned during the process of the lifting component 20 rising relative to the frame 10.

[0066] In addition, when the fruit box filled with fruits and vegetables descends onto the roller 50, the rotating limiting component 26 can open the outlet of the receiving cavity 202, so that a new empty fruit box can enter the receiving cavity 202 and push the fruit box filled with fruits and vegetables out of the receiving cavity 202.

[0067] Specifically, in this embodiment, the mounting frame 24 can be a steel frame structure, and openings can be provided on opposite sides of the mounting frame 24 so that the fruit box can enter and exit the receiving cavity 202; the rotation limiting component 26 can include a cylinder-driven rod-shaped component.

[0068] In other embodiments, the rotation limiting member 26 may also include other structures, such as a motor-driven rod structure.

[0069] In some embodiments, the rotation limiting component 26 includes a first rotation drive 262 and a rotation rod 264. The first rotation drive 262 is mounted on one side of the mounting bracket 24. The first rotation drive 262 is used to drive the rotation rod 264 to rotate. The rotation axis of the rotation rod 264 is perpendicular to the rotation axis of the roller component 50. The first rotation drive 262 drives the rotation rod 264 to rotate to a position parallel to the horizontal plane to close the outlet of the receiving cavity 202. The first rotation drive 262 drives the rotation rod 264 to rotate to a position perpendicular to the horizontal plane to open the outlet of the receiving cavity 202.

[0070] With the above structure, the first rotation drive 262 can drive the rotation rod 264 to rotate; when the first rotation drive 262 drives the rotation rod 264 to a position parallel to the horizontal plane, one side of the fruit box abuts against the rotation rod 264, so the fruit box will not move out of the receiving cavity 202, that is, the outlet of the receiving cavity 202 is closed; when the first rotation drive 262 drives the rotation rod 264 to a position perpendicular to the horizontal plane, the rotation rod 264 is located on one side of the mounting bracket 24, so the fruit box can move out of the receiving cavity 202, that is, the outlet of the receiving cavity 202 is opened.

[0071] Specifically, in this embodiment, the first rotation drive member 262 may include a cylinder-driven connecting rod, which is connected between the cylinder and the rotating rod 264. During the cylinder push, the rotating rod 264 can be driven to rotate through the connecting rod. The connecting rod may be a strip structure with a cross-section similar to a rectangle.

[0072] In other embodiments, the first rotation drive 262 may also include other structures, such as an electric motor, the rotation shaft of which may be directly connected to the rotation rod 264; the rotation rod 264 may also be other structures, such as a straight rod with a circular or elliptical cross section.

[0073] Please refer to Figure 4 In some embodiments, the drive assembly 30 includes a drive component 32, a chain component 34, and a sprocket component 36. The drive component 32 is mounted below the frame 10, the sprocket component 36 is rotatably connected to the frame 10, the chain component 34 is sleeved on the sprocket component 36, and the lifting assembly 20 is fixed to the chain component 34. The drive component 32 is used to drive the sprocket component 36 to move, thereby driving the chain component 34 to move, so as to drive the lifting assembly 20 to move vertically relative to the frame 10.

[0074] With the above structure, the drive component 32 drives the lifting component 20 to move vertically relative to the frame 10 through the sprocket component 36 and the chain component 34, so that the lifting component 20 is more stable during the rising or falling process, so as to prevent the fruits and vegetables in the fruit box from falling out of the fruit box due to the shaking of the fruits and vegetables.

[0075] Specifically, the drive component 32 can be an electric motor, the number of sprocket components 36 can be two, and the number of chain components 34 can be two. Each end of the chain component 34 is fitted onto a corresponding sprocket component 36. Both chain components 34 are perpendicular to the horizontal plane, and the two sprocket components 36 at the same height can be connected to each other by a connecting rod. The drive component 32 can be fixed to the lower side of the frame 10 by screws. The drive component 32 can drive the two sprocket components 36 to rotate simultaneously through the connecting rod located at the lower end of the drive assembly 30, so as to drive the two chain components 34 to move synchronously.

[0076] In some embodiments, the fruit box fixing assembly 40 includes a positioning component 42 and three rotating expansion components 44, which are respectively located at the four sides of the opening of the fruit box. The positioning component 42 is mounted on the frame 10, and the rotating expansion components 44 are rotatably connected to the frame 10. During the process of the drive assembly 30 driving the lifting assembly 20 to rise, the positioning component 42 and the three rotating expansion components 44 can extend into the fruit box located in the receiving cavity 202. The positioning component 42 abuts against one inner side wall of the fruit box, and the rotating expansion components 44 can rotate and abut against the corresponding inner side wall of the fruit box.

[0077] With the above structure, during the process of the lifting assembly 20 driving the fruit box to rise, the positioning component 42 and the three rotating support components 44 can simultaneously extend into the opening of the fruit box. The positioning component 42 abuts against one inner side wall of the fruit box, and the rotating support components 44 rotate relative to the frame 10. Each rotating support component 44 can abut against the inner side wall of a corresponding fruit box, thereby the fruit box fixing assembly 40 plays a role in fixing the fruit box.

[0078] Specifically, in this embodiment, the positioning component 42 and the three rotating and spreading components 44 all include steel plate-like structures, and the rotating and spreading components 44 may include cylinders; in the horizontal direction, the positioning component 42 and the three rotating and spreading components 44 are respectively located at the four sides of the rectangle.

[0079] In other embodiments, the positioning component 42 and the rotating spreading component 44 may also include other structures, such as steel strip structures; the rotating spreading component 44 may also be driven by other structures, such as electric motors.

[0080] Please refer to Figure 1 and Figure 2 In some embodiments, the number of fruit box fixing components 40 is two, and the positioning component 42 includes guide inclined walls 422, the upper ends of the two guide inclined walls 422 are connected to each other; in the direction from top to bottom, each guide inclined wall 422 is inclined away from the other guide inclined wall 422.

[0081] With the above structure, there are two fruit box fixing components 40, so that the fruit box positioning mechanism 100 can simultaneously position two fruit boxes, allowing fruits and vegetables to be loaded into both boxes at the same time, further improving the packing efficiency. In the top-to-bottom direction, each guide wall 422 is inclined away from the other guide wall 422, so that as the fruit box fixing component 40 extends into the fruit box, the guide wall 422 guides the fruit box, further reducing the possibility of the fruit box and the fruit box fixing component 40 misaligning.

[0082] Specifically, in this embodiment, the guide inclined wall 422 can be a plate-like structure similar to a rectangle. In other embodiments, the guide inclined wall 422 can also be other structures, such as a semi-circular or inverted triangular plate-like structure.

[0083] Please refer to Figure 5 and Figure 6 In some embodiments, the fruit box fixing assembly 40 further includes a pressing bracket 46 and a vertical drive member 48. The vertical drive member 48 is mounted on the frame 10 and is used to drive the pressing bracket 46 to move vertically relative to the frame 10. The upper ends of the two guide inclined walls 422 are respectively connected to the opposite sides of the pressing bracket 46. During the process of the vertical drive member 48 driving the pressing bracket 46 to move downward, the pressing bracket 46 can abut against the upper end of the side wall of the fruit box.

[0084] With the above structure, as the driving component 30 drives the lifting component 20 to move upward, the guide inclined wall 422 extends into a corresponding fruit box, and the vertical driving component 48 drives the pressing bracket 46 to move downward, so that the pressing bracket 46 can abut against the upper end of the side wall of the fruit box. The pressing bracket 46 and the lifting component 20 together clamp the fruit box, so that the fruit box can be more stable during the fruit and vegetable packing process.

[0085] Specifically, the pressure box bracket 46 may include two strip-shaped sheet metal structures. The pressure box bracket 46 may be inverted "V" shape in side view. Both ends of the pressure box bracket 46 can be vertically connected to the frame 10 via guide members. The positioning component 42 may be located in the middle of the pressure box bracket 46. The vertical drive component 48 may be a cylinder positioned vertically. The vertical drive component 48 may be fixed to the frame 10. Each opposite end of the pressure box bracket 46 may be connected to a corresponding vertical drive component 48, enabling the vertical drive component 48 to drive the pressure box bracket 46 to move vertically relative to the frame 10.

[0086] Please refer to Figure 7In some embodiments, the rotating support component 44 includes a second rotating drive 442 and a limiting plate 444. The limiting plate 444 is rotatably connected to the frame 10. The second rotating drive 442 is used to drive the limiting plate 444 to rotate relative to the frame 10, so that the limiting plate 444 can abut against a corresponding inner sidewall of the fruit box.

[0087] With the above structure, before the fruit box fixing assembly 40 extends into the fruit box, the limiting plate 444 can be tilted relative to the horizontal plane, so that the limiting plate 444 can be more easily inserted into the opening of the fruit box; after the limiting plate 444 extends into the fruit box, the second rotation drive member 442 can drive the limiting plate 444 to rotate to a position perpendicular to the horizontal plane, and the limiting plate 444 can abut against one of the inner side walls of the fruit box.

[0088] Specifically, the second rotation drive 442 may include a cylinder and a transmission block. The upper side of the limiting plate 444 is rotatably connected to the frame 10 via a rotating shaft. The cylinder is connected to the rotating shaft of the limiting plate 444 via the transmission block. During the extension or retraction of the cylinder, the limiting plate 444 can be driven to rotate relative to the frame 10 via the transmission block.
