Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a fruit and vegetable packing 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 packing mechanisms may include fruit and vegetable conveying components and loading and unloading components. The fruit and vegetable conveying components are used to convey a preset weight of fruits and vegetables into the loading and unloading components, and the loading and unloading components are used to pack the fruits and vegetables into a corresponding empty fruit box. After each packing is completed, the fruit and vegetable conveying components can convey the preset weight of fruits and vegetables into the loading and unloading components again to achieve automation of fruit and vegetable packing.

[0004] However, when fruits and vegetables fall into the loading and unloading assembly, they may hit the inner wall of the assembly, causing them to fall and get injured. Utility Model Content

[0005] The present invention aims to provide a fruit and vegetable packing mechanism and a fruit and vegetable sorting device to solve the technical problem in the prior art that when fruits and vegetables fall into the loading and unloading assembly, they may hit the inner wall of the loading and unloading assembly, causing the fruits and vegetables to be injured.

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

[0007] A fruit and vegetable packing mechanism is provided, comprising:

[0008] frame;

[0009] The loading and unloading assembly is movably mounted on the frame in the vertical direction, and the loading and unloading assembly has a receiving cavity, a feed inlet and a discharge outlet;

[0010] A switch assembly is installed on the loading and unloading assembly. The switch assembly includes a flexible blocking component and a switch driving component. The switch driving component is used to drive the flexible blocking component to open or close the discharge port.

[0011] An elastic blocking member is provided, the upper side of which is connected to the frame, the lower side of which is installed on the loading and unloading assembly, and the elastic blocking member covers the lower side of the discharge port.

[0012] With the above structure, when the user loads fruits and vegetables into the loading and unloading assembly, the loading and unloading assembly can be moved to a higher position relative to the frame. Then, the fruits and vegetables are placed into the inlet. The distance between the fruits and vegetables and the bottom wall of the receiving cavity is relatively short, and the fruits and vegetables contact the bottom wall of the receiving cavity at a slower speed, thereby reducing the possibility of the fruits and vegetables being injured by falling.

[0013] In addition, the elastic barrier covers the lower side of the discharge port, and the flexible barrier is located at the discharge port; thus, when fruits and vegetables come into contact with the elastic barrier or the flexible barrier, the elastic barrier or the flexible barrier can cushion the fruits and vegetables, further reducing the possibility of fruits and vegetables being injured by falling.

[0014] Once the preset weight of fruits and vegetables is loaded into the receiving cavity, the loading and unloading components move downward relative to the frame. The user can then stop loading fruits and vegetables into the receiving cavity and move the fruit box to the discharge port. The switch drive component drives the flexible blocking component to open the discharge port, and the fruits and vegetables in the receiving cavity fall into the fruit box under the action of gravity, thus completing the packing of fruits and vegetables.

[0015] In some embodiments, the fruit and vegetable packing mechanism further includes a vertical drive assembly, which includes a vertical drive component and a telescopic component. The vertical drive component is mounted on the top of the frame, and the telescopic component is mounted on the vertical drive component. The vertical drive component is used to drive the telescopic component to retract upward or extend downward. The loading and unloading assembly is fixed to the end of the telescopic component facing away from the vertical drive component.

[0016] With the above structure, the vertical drive assembly is used to drive the loading and unloading assembly to move vertically relative to the frame, so that when the user inputs fruits and vegetables into the receiving cavity through the inlet, the vertical drive assembly can adjust the height of the loading and unloading assembly relative to the frame, thereby adjusting the height of the inlet relative to the frame.

[0017] When the vertical drive component retracts the telescopic component upwards, the telescopic component moves the loading / unloading assembly vertically upwards relative to the frame. When the vertical drive component extends the telescopic component downwards, the telescopic component moves the loading / unloading assembly vertically downwards relative to the frame. The cooperation between the vertical drive component and the telescopic component simplifies the structure of the vertical drive assembly; and the telescopic component can continuously apply an upward vertical pulling force to the loading / unloading assembly, making the loading / unloading assembly more stable during vertical movement.

[0018] In some embodiments, the frame includes two guide rails perpendicular to the horizontal plane, and the two guide rails are located on opposite sides of the loading and unloading assembly; the loading and unloading assembly includes two guide blocks, each guide block being connected to a corresponding guide rail.

[0019] Through the above structure, the guide rail can guide the loading and unloading components via a corresponding guide block, so that the loading and unloading components can move stably in the vertical direction relative to the frame, thereby improving the overall stability of the fruit and vegetable packing mechanism.

[0020] In some embodiments, the switch driving component includes a first mounting rod and two switch driving structures, the two switch driving structures being respectively mounted on opposite sides of the loading and unloading assembly, and the opposite ends of the first mounting rod being respectively connected to the two switch driving structures; one side of the flexible blocking component is connected to the first mounting rod, and the other opposite side of the flexible blocking component is connected to one side of the loading and unloading assembly;

[0021] The switch drive structure is used to drive the first mounting rod to move between the opposite sides of the discharge port. The movement direction of the first mounting rod is perpendicular to the arrangement direction of the two switch drive structures, so that the flexible blocking component opens or closes the discharge port.

[0022] With the above structure, two switch drive structures are respectively installed on opposite sides of the loading and unloading assembly, so that the switch drive structures can drive the flexible blocking component to move more stably; the switch drive structure is used to drive the first mounting rod to move between opposite sides of the discharge port, and the end of the flexible blocking component is connected to the first mounting rod; when the first mounting rod is located on one side of the discharge port, the upper surface of the flexible blocking component can cover the discharge port to close the discharge port; when the first mounting rod is located on the other opposite side of the discharge port, the flexible blocking component can be offset from the discharge port to open the discharge port.

[0023] In some embodiments, the switch drive structure includes a rotating pusher and a rotating rod. The upper end of the rotating rod is rotatably connected to the upper end of the loading / unloading assembly, and the lower end of the rotating rod assembly is connected to the first mounting rod. One end of the rotating pusher is rotatably connected to the loading / unloading assembly, and the other opposite end of the rotating pusher is rotatably connected to the rotating rod. The rotating pusher is used to push the rotating rod to rotate relative to the loading / unloading assembly, thereby driving the first mounting rod to move between the opposite sides of the feed inlet.

[0024] With the above structure, the upper end of the rotating rod is rotatably connected to the upper end of the loading and unloading assembly, the lower end of the rotating rod is connected to the first mounting rod, and the end of the rotating pusher is connected between the two ends of the rotating rod. This makes the distance from the connection point of the rotating pusher and the rotating rod to the rotation axis of the rotating rod less than the distance from the first mounting rod to the central axis of the rotating rod. The stroke of the rotating pusher when it pushes is less than the stroke of the first mounting rod. As a result, the size of the rotating pusher can be smaller, and the switch drive structure is easier to assemble.

[0025] In some embodiments, the loading and unloading assembly includes a main body, a vertical pulling component, and a second mounting rod. The receiving cavity, the inlet, and the outlet are all opened in the main body. The two switch driving structures are respectively installed on opposite sides of the main body. The vertical pulling component and the second mounting rod are both installed in the main body, and the vertical pulling component is located above the second mounting rod.

[0026] The flexible blocking component is connected to the vertical pulling component at one end facing away from the first mounting rod. The vertical pulling component is used to drive the flexible blocking component at one end facing away from the first mounting rod to move in the vertical direction. The second mounting rod is located on the side of the discharge port facing the vertical pulling component. The second mounting rod contacts the middle of the flexible blocking component and supports the flexible blocking component.

[0027] With the above structure, the vertical pulling component provides tension to the end of the flexible blocking component facing away from the first mounting rod, so that the flexible blocking component can be straightened when the outlet is closed, preventing fruits and vegetables from falling out through the gap between the flexible blocking component and the main body. In addition, the second mounting rod contacts the middle of the flexible blocking component and supports the flexible blocking component; so that the part of the flexible blocking component covering the outlet can be parallel to the horizontal plane and fit against the lower surface of the main body, further improving the airtightness when the outlet is closed.

[0028] In some embodiments, the vertical pulling component includes an elastic pulling member, a connecting member, and a third mounting rod. The upper end of the elastic pulling member is connected to the upper end of the main body, the lower end of the elastic pulling member is connected to the connecting member, and the third mounting rod is mounted on the connecting member.

[0029] The flexible blocking component is a belt structure. One end of the flexible blocking component is sleeved on the first mounting rod, the other opposite end of the flexible blocking component is sleeved on the third mounting rod, and the middle part of the flexible blocking component is sleeved on the second mounting rod.

[0030] With the above structure, the upper end of the elastic pull member is connected to the upper end of the main body, the lower end of the elastic pull member is connected to the connector, and the third mounting rod is installed on the connector. When the flexible blocking member closes the discharge port, the elastic pull member provides a pulling force to the third mounting rod and can also extend, so that the height of the third mounting rod is reduced. The extension of the flexible blocking member is less than the length of the discharge port, which plays a buffering role for the flexible blocking member, so as to avoid the flexible blocking member from over-extending and becoming loose.

[0031] In some embodiments, the elastic blocking member includes a parallel segment and a vertical segment connected to each other, the parallel segment being located below the parallel segment, one end of the parallel segment facing the loading and unloading assembly being connected to the upper part of the vertical segment, and the other end of the parallel segment facing away from the loading and unloading assembly being fixed to the frame.

[0032] The lower side of the vertical section is installed on the loading and unloading assembly, and the vertical section covers the portion of the feed inlet located below the parallel section.

[0033] With the above structure, the vertical section covers the part of the feed inlet located below the parallel section. During the downward movement of the loading and unloading components, the parallel section and the vertical section are stretched together, which reduces the elongation ratio of the elastic blocking component after stretching and reduces the possibility of the elastic blocking component relaxing after resetting.

[0034] In some embodiments, the frame includes a rotating support roller that abuts against the connection between the vertical section and the parallel section, the vertical section being located between the rotating support roller and the loading / unloading assembly; the length of the vertical section is less than the length of the parallel section.

[0035] With the above structure, a vertical section and a parallel section are formed under the support of the rotating support roller. The rotating support roller abuts against the connection between the vertical section and the parallel section. During the stretching process, the rotating support roller can rotate, and rolling friction is generated between the rotating support roller and the elastic blocking component, which reduces the wear of the elastic blocking component and improves its durability.

[0036] Another embodiment of this utility model provides a fruit and vegetable sorting device, including the fruit and vegetable packing mechanism in any of the above embodiments.

[0037] Compared with existing technologies, when users load fruits and vegetables into the loading and unloading components, they can move the components to a higher position relative to the frame, and then put the fruits and vegetables into the inlet. The distance between the fruits and vegetables and the bottom wall of the receiving cavity is closer, and the fruits and vegetables contact the bottom wall of the receiving cavity at a slower speed, thereby reducing the possibility of fruits and vegetables being injured by falling.

[0038] In addition, the elastic barrier covers the lower side of the discharge port, and the flexible barrier is located at the discharge port; thus, when fruits and vegetables come into contact with the elastic barrier or the flexible barrier, the elastic barrier or the flexible barrier can cushion the fruits and vegetables, further reducing the possibility of fruits and vegetables being injured by falling.

[0039] Once the preset weight of fruits and vegetables is loaded into the receiving cavity, the loading and unloading components move downward relative to the frame. The user can then stop loading fruits and vegetables into the receiving cavity and move the fruit box to the discharge port. The switch drive component drives the flexible blocking component to open the discharge port, and the fruits and vegetables in the receiving cavity fall into the fruit box under the action of gravity, thus completing the packing of fruits and vegetables.

[0049] 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.

[0050] The following detailed description, in conjunction with all the accompanying drawings, of a fruit and vegetable packing mechanism 100 and a fruit and vegetable sorting device provided in this application, will be provided through specific embodiments.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 One embodiment of this utility model discloses a fruit and vegetable packing mechanism 100, including a frame 10, a loading and unloading assembly 20, a switch assembly 30, and an elastic blocking member 40. The loading and unloading assembly 20 is movably mounted on the frame 10 in the vertical direction, and the loading and unloading assembly 20 has a receiving cavity 2202, a feeding port 2204, and a discharging port 2206. The switch assembly 30 is mounted on the loading and unloading assembly 20, and the switch assembly 30 includes a flexible blocking member 32 and a switch driving member 34. The switch driving member 34 is used to drive the flexible blocking member 32 to open or close the discharging port 2206. The upper side of the elastic blocking member 40 is connected to the frame 10, and the lower side of the elastic blocking member 40 is mounted on the loading and unloading assembly 20, and the elastic blocking member 40 covers the lower side of the discharging port 2206.

[0052] With the above structure, when the user loads fruits and vegetables into the loading and unloading assembly 20, the loading and unloading assembly 20 can be moved to a higher position relative to the frame 10. Then, the fruits and vegetables are placed into the inlet 2204. The distance between the fruits and vegetables and the bottom wall of the receiving cavity 2202 is relatively short, and the fruits and vegetables contact the bottom wall of the receiving cavity 2202 at a slower speed, thereby reducing the possibility of the fruits and vegetables being injured by falling.

[0053] In addition, the elastic blocking member 40 covers the lower side of the discharge port 2206, and the flexible blocking member 32 is located at the discharge port 2206; thus, when fruits and vegetables come into contact with the elastic blocking member 40 or the flexible blocking member 32, the elastic blocking member 40 or the flexible blocking member 32 can buffer the fruits and vegetables, further reducing the possibility of fruits and vegetables being injured by falling.

[0054] After the preset weight of fruits and vegetables is loaded into the receiving cavity 2202, the loading and unloading assembly 20 moves downward relative to the frame 10. The user can stop loading fruits and vegetables into the receiving cavity 2202 and move the fruit box to the discharge port 2206. The switch drive component 34 drives the flexible blocking component 32 to open the discharge port 2206. The fruits and vegetables in the receiving cavity 2202 fall into the fruit box under the action of gravity to complete the packing of fruits and vegetables.

[0055] Specifically, in this embodiment, the frame 10 may include steel plates and steel bars spliced ​​together, and the frame 10 may have a hollow frame structure; the loading and unloading assembly 20 may move vertically relative to the fruit and vegetable packing mechanism 100, and the loading and unloading assembly 20 may have a structure similar to a cuboid, the inlet 2204 may be located on one side of the loading and unloading assembly 20, and both the inlet 2204 and the outlet 2206 may be openings similar to rectangles.

[0056] The flexible blocking component 32 may include an elastic annular belt, and the width of the flexible blocking component 32 may be equal to or greater than the width of the discharge port 2206. The switch driving component 34 may include a cylinder-driven rotating structure. One end of the flexible blocking component 32 may be sleeved on the rotating structure, and the other opposite end of the flexible blocking component 32 may be sleeved on the loading and unloading assembly 20. The rotating structure can drive the end of the flexible blocking component 32 to move between the opposite sides of the discharge port 2206, so that the flexible blocking component 32 covers the discharge port 2206 or is offset from the discharge port 2206, so as to realize the opening or closing of the discharge port 2206 by the flexible blocking component 32.

[0057] The elastic stopper 40 may include a rectangular elastic belt, and the end of the elastic stopper 40 may be fixed to the frame 10 and the loading / unloading assembly 20 by a fixing plate.

[0058] In other embodiments, the frame 10 may also include other structures, such as a hollow box structure; the loading and unloading assembly 20 may also be in other shapes, such as a cylinder or a column with a polygonal cross-section; the switching assembly 30 may also include other structures, such as a flexible stop driven by a motor, which can cover the discharge port 2206 or be offset from the discharge port 2206.

[0059] In some embodiments, the fruit and vegetable packing mechanism 100 further includes a vertical drive assembly 50, which includes a vertical drive component 52 and a telescopic component 54. The vertical drive component 52 is mounted on the top of the frame 10, and the telescopic component 54 is mounted on the vertical drive component 52. The vertical drive component 52 is used to drive the telescopic component 54 to retract upward or extend downward. The loading and unloading assembly 20 is fixed to one end of the telescopic component 54 facing away from the vertical drive component 52.

[0060] With the above structure, the vertical drive assembly 50 is used to drive the loading and unloading assembly 20 to move vertically relative to the frame 10, so that when the user inputs fruits and vegetables into the receiving cavity 2202 through the inlet 2204, the vertical drive assembly 50 can adjust the height of the loading and unloading assembly 20 relative to the frame 10, thereby adjusting the height of the inlet 2204 relative to the frame 10.

[0061] When the vertical drive component 52 drives the telescopic component 54 to retract upwards, the telescopic component 54 causes the loading / unloading assembly 20 to move upwards in the vertical direction relative to the frame 10; when the vertical drive component 52 drives the telescopic component 54 to extend downwards, the telescopic component 54 causes the loading / unloading assembly 20 to move downwards in the vertical direction relative to the frame 10. The vertical drive component 52 and the telescopic component 54 cooperate with each other, which can simplify the structure of the vertical drive assembly 50; and the telescopic component 54 can continuously apply a vertically upward pulling force to the loading / unloading assembly 20, so that the loading / unloading assembly 20 is more stable during vertical movement.

[0062] Specifically, the vertical drive component 52 may include a motor, and the telescopic component 54 may include a belt reel, which may be mounted on the drive shaft of the motor. One protruding end of the telescopic component 54 may be fixed to the loading / unloading assembly 20; the vertical drive component 52 drives the telescopic component 54 to rotate in a preset direction, the protruding part of the telescopic component 54 lengthens, and the loading / unloading assembly 20 moves downward; the vertical drive component 52 drives the telescopic component 54 to rotate away from the preset direction, the protruding part of the telescopic component 54 shortens, and the loading / unloading assembly 20 moves upward.

[0063] In some embodiments, the frame 10 includes two guide rails 12, which are perpendicular to the horizontal plane and are located on opposite sides of the loading and unloading assembly 20. The loading and unloading assembly 20 includes two guide blocks 22, each of which is connected to a corresponding guide rail 12.

[0064] Through the above structure, the guide rail 12 can guide the loading and unloading assembly 20 through a corresponding guide block 22, so that the loading and unloading assembly 20 can move stably in the vertical direction relative to the frame 10, thereby improving the overall stability of the fruit and vegetable packing mechanism 100.

[0065] Specifically, the guide rail 12 may include a strip-shaped protrusion, which may be embedded in the guide block 22 so that the guide block 22 can move vertically relative to the guide rail 12; the two guide rails 12 may be located at the two corners on the same side of the loading and unloading assembly 20, so that the two guide rails 12 are located on opposite sides of the loading and unloading assembly 20.

[0066] In some embodiments, the switch driving component 34 includes a first mounting rod 342 and two switch driving structures 344, which are respectively mounted on opposite sides of the loading / unloading assembly 20. The opposite ends of the first mounting rod 342 are respectively connected to the two switch driving structures 344. One side of the flexible blocking component 32 is connected to the first mounting rod 342, and the other opposite side of the flexible blocking component 32 is connected to one side of the loading / unloading assembly 20.

[0067] The switch drive structure 344 is used to drive the first mounting rod 342 to move between the opposite sides of the discharge port 2206. The movement direction of the first mounting rod 342 is perpendicular to the arrangement direction of the two switch drive structures 344, so that the flexible blocking component 32 opens or closes the discharge port 2206.

[0068] With the above structure, two switch drive structures 344 are respectively installed on opposite sides of the loading and unloading assembly 20, so that the switch drive structure 344 can drive the flexible blocking component 32 to move more stably; the switch drive structure 344 is used to drive the first mounting rod 342 to move between opposite sides of the discharge port 2206, and the end of the flexible blocking component 32 is connected to the first mounting rod 342; when the first mounting rod 342 is located on one side of the discharge port 2206, the upper surface of the flexible blocking component 32 can cover the discharge port 2206 to close the discharge port 2206; when the first mounting rod 342 is located on the other opposite side of the discharge port 2206, the flexible blocking component 32 can be offset from the discharge port 2206 to open the discharge port 2206.

[0069] Specifically, in this embodiment, the switch drive structure 344 may include a cylinder and a rotating rod structure, which drives the rotating rod structure to rotate so as to move the first mounting rod 342 relative to the discharge port 2206 of the loading and unloading assembly 20.

[0070] In other embodiments, the switch drive structure 344 may also include other structures, such as a motor-driven slider structure, wherein the first mounting rod 342 may be fixed to the slider.

[0071] In some embodiments, the switch drive structure 344 includes a rotating pusher 3442 and a rotating rod 3444. The upper end of the rotating rod 3444 is rotatably connected to the upper end of the loading / unloading assembly 20, and the lower end of the rotating rod 3444 assembly is connected to the first mounting rod 342. One end of the rotating pusher 3442 is rotatably connected to the loading / unloading assembly 20, and the other opposite end of the rotating pusher 3442 is rotatably connected to the rotating rod 3444. The rotating pusher 3442 is used to push the rotating rod 3444 to rotate relative to the loading / unloading assembly 20, so as to drive the first mounting rod 342 to move between the opposite sides of the feed inlet 2204.

[0072] With the above structure, the upper end of the rotating rod 3444 is rotatably connected to the upper end of the loading / unloading assembly 20, the lower end of the rotating rod 3444 is connected to the first mounting rod 342, and the end of the rotating pusher 3442 is connected between the two ends of the rotating rod 3444. This makes the distance from the connection point of the rotating pusher 3442 and the rotating rod 3444 to the rotation axis of the rotating rod 3444 less than the distance from the first mounting rod 342 to the central axis of the rotating rod 3444. The stroke of the rotating pusher 3442 when it pushes is less than the stroke of the first mounting rod 342. As a result, the size of the rotating pusher 3442 can be smaller, and the switch drive structure 344 is easier to assemble.

[0073] Specifically, in this embodiment, the rotating pusher 3442 may include a cylinder. The cylinder body of the rotating pusher 3442 can be rotatably connected to the loading and unloading assembly 20 via a rotating shaft. The piston rod of the rotating pusher 3442 cylinder can be rotatably connected to the middle of the rotating rod 3444 via a bearing. The connection between the pusher and the rotating rod 3444 can be closer to the end of the rotating axis of the rotating rod 3444.

[0074] In other embodiments, the rotating pusher 3442 may also include other structures, such as a slider driven by an electric motor; the connection between the rotating pusher 3442 and the rotating rod 3444 may be closer to the end where the first mounting rod 342 is located.

[0075] In some embodiments, the loading and unloading assembly 20 includes a main body 24, a vertical pulling component 26, and a second mounting rod 28. The receiving cavity 2202, the feed port 2204, and the discharge port 2206 are all opened on the main body 24. Two switch drive structures 344 are respectively installed on opposite sides of the main body 24. The vertical pulling component 26 and the second mounting rod 28 are both installed on the main body 24, with the vertical pulling component 26 located above the second mounting rod 28.

[0076] The end of the flexible blocking component 32 facing away from the first mounting rod 342 is connected to the vertical pulling component 26. The vertical pulling component 26 is used to drive the end of the flexible blocking component 32 facing away from the first mounting rod 342 to move in the vertical direction. The second mounting rod 28 is located on the side of the discharge port 2206 facing the vertical pulling component 26. The second mounting rod 28 contacts the middle of the flexible blocking component 32 and supports the flexible blocking component 32.

[0077] Through the above structure, the vertical pulling component 26 provides a pulling force to the end of the flexible blocking component 32 facing away from the first mounting rod 342, so that the flexible blocking component 32 can be straightened when the discharge port 2206 is closed, preventing fruits and vegetables from falling out through the gap between the flexible blocking component 32 and the main body 24. In addition, the second mounting rod 28 contacts the middle of the flexible blocking component 32 and supports the flexible blocking component 32; so that the part of the flexible blocking component 32 covering the discharge port 2206 can be parallel to the horizontal plane and fit against the lower surface of the main body 24, further improving the airtightness of the discharge port 2206 when closed.

[0078] Specifically, the flexible blocking component 32 can be made of elastic materials such as rubber or soft leather; the flexible blocking component 32 can be a ring structure with its ends connected, one end of the flexible blocking component 32 being sleeved on the first mounting rod 342, and the middle part of the flexible blocking component 32 being sleeved on the second mounting rod 28. The vertical pulling component 26 can include an elastic material so that the vertical pulling component 26 can buffer the flexible blocking component 32. The vertical pulling component 26 and the second mounting rod 28 are both located between the two switch drive structures 344.

[0079] Please refer to Figure 4 In some embodiments, the vertical pulling component 26 includes an elastic pulling member 262, a connecting member 264, and a third mounting rod 266. The upper end of the elastic pulling member 262 is connected to the upper end of the main body 24, the lower end of the elastic pulling member 262 is connected to the connecting member 264, and the third mounting rod 266 is mounted on the connecting member 264.

[0080] The flexible blocking component 32 is a belt structure. One end of the flexible blocking component 32 is sleeved on the first mounting rod 342, the other opposite end of the flexible blocking component 32 is sleeved on the third mounting rod 266, and the middle part of the flexible blocking component 32 is sleeved on the second mounting rod 28.

[0081] With the above structure, the upper end of the elastic pull member 262 is connected to the upper end of the main body 24, the lower end of the elastic pull member 262 is connected to the connector 264, and the third mounting rod 266 is mounted on the connector 264. When the flexible blocking member 32 closes the discharge port 2206, the elastic pull member 262 provides a pulling force to the third mounting rod 266 and can also extend, so that the height of the third mounting rod 266 is reduced. The extension of the flexible blocking member 32 is less than the length of the discharge port 2206, which plays a buffering role for the flexible blocking member 32 to avoid the flexible blocking member 32 from over-extending and becoming loose.

[0082] Specifically, in this embodiment, the elastic pull member 262 can have the same structure as the flexible blocking member 32. The upper end of the elastic pull member 262 is sleeved on the upper end of the main body 24, and the lower end of the elastic pull member 262 can be sleeved on the connector 264. The connector 264 can be a hollow block structure, and the third mounting rod 266 can be installed on the lower end of the connector 264.

[0083] In other embodiments, the elastic pull member 262 may also be other structures, such as a tension spring.

[0084] Please refer to Figure 5 In some embodiments, the elastic blocking member 40 includes a parallel segment 42 and a vertical segment 44 connected to each other. The parallel segment 42 is located below the parallel segment 42. One end of the parallel segment 42 facing the loading / unloading assembly 20 is connected to the upper part of the vertical segment 44. The other end of the parallel segment 42 facing away from the loading / unloading assembly 20 is fixed to the frame 10.

[0085] The lower side of the vertical section 44 is installed on the loading and unloading assembly 20, and the vertical section 44 covers the part of the feed inlet 2204 located below the parallel section 42.

[0086] With the above structure, the vertical section 44 covers the part of the feed inlet 2204 located below the parallel section 42. During the downward movement of the loading and unloading assembly 20, the parallel section 42 and the vertical section 44 are stretched together, which reduces the elongation ratio of the elastic blocking member 40 after stretching and reduces the possibility of the elastic blocking member 40 relaxing after resetting.

[0087] Specifically, in this embodiment, the parallel segment 42 is arranged parallel to the horizontal plane, the vertical segment 44 is arranged perpendicular to the horizontal plane, and the length of the parallel segment 42 is greater than the length of the vertical segment 44; the elastic blocking member 40 is always in a tensioned state.

[0088] In other embodiments, the length of the vertical segment 44 may also be greater than or equal to the length of the parallel segment 42.

[0089] In some embodiments, the frame 10 includes a rotating support roller 14, which abuts against the connection between the vertical section 44 and the parallel section 42. The vertical section 44 is located between the rotating support roller 14 and the loading / unloading assembly 20. The length of the vertical section 44 is less than the length of the parallel section 42.

[0090] With the above structure, a vertical section 44 and a parallel section 42 are formed under the support of the rotating support roller 14. The rotating support roller 14 abuts against the connection between the vertical section 44 and the parallel section 42. During the stretching process of the elastic blocking member 40, the rotating support roller 14 can rotate, and rolling friction is generated between the rotating support roller 14 and the elastic blocking member 40, which reduces the wear of the elastic blocking member 40 and improves the durability of the elastic blocking member 40.

[0091] Specifically, the rotating support roller 14 can have a cylindrical structure, and the rotating support roller 14 can be rotatably connected to the frame 10 via a rotating shaft.
