Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a one-way release structure, a transmission module 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 apples, pears, and tomatoes, among others. 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, packaging boxes used to hold fruits and vegetables need to pass through a transmission module. The transmission module may include a cross channel, which generally includes a motor-driven conveyor belt. The cross channel includes two input ports and one output port. The packaging boxes enter from the two input ports and exit from the same output port.
[0004] However, when a box moves from one of the two input ports to the output port, the two boxes may collide, causing the output port of the one-way release structure to become blocked. Utility Model Content
[0005] The present invention aims to provide a one-way release structure, a transmission module, and a fruit and vegetable sorting device to solve the technical problem in the prior art where, when a package moves from one of the two input ports to the output port, the two packages may collide, causing the output port of the one-way release structure to become blocked.
[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution:
[0007] A one-way release structure is provided, including:
[0008] Mounting base;
[0009] A first limiting assembly includes a first limiting component and a first elastic reset component. The first limiting component is rotatably connected to the mounting base, and the first elastic reset component is disposed between the first limiting component and the mounting base. The first elastic reset component is used to drive the first limiting component to reset, and the first limiting component extends in a direction away from the rotation axis of the first limiting component.
[0010] The second limiting component includes a second limiting member and a second elastic reset member. The second limiting member is rotatably connected to the mounting base, and the rotation axis of the second limiting member is parallel to the rotation axis of the first limiting member. The second elastic reset member is disposed between the second limiting member and the mounting base. The second elastic reset member is used to drive the second limiting member to reset. The second limiting member extends in a direction away from the rotation axis of the second limiting member. When both the first elastic reset member and the second elastic reset member are reset, the first limiting member and the second limiting member form a preset angle.
[0011] A rotation limiting assembly is mounted on the mounting base. When one of the first limiting component and the second limiting component rotates, it can abut against the rotation limiting assembly, causing the rotation limiting assembly to move to the other and limit the rotation of the other.
[0012] With the above structure, when the packaging box moves to the output end of the first input channel, the packaging box can press against the first limiting component, so that the first limiting component rotates relative to the mounting base. Then, the packaging box located from the first input channel to the output end can flow into the output channel. At the same time, after the first limiting component rotates, it abuts against the rotation limiting component. The rotation limiting component moves to the second limiting component and limits the rotation of the second limiting component. So that during the process of the packaging box located from the first input channel to the output end flowing into the output channel, the packaging box located from the second input channel to the output end will be blocked by the second limiting component, so as to avoid multiple packaging boxes blocking the input end of the output channel.
[0013] In addition, when the packaging box moves to the output end of the second input channel, the packaging box can press against the second limiting component, so that the second limiting component rotates relative to the mounting base. This allows the packaging box located from the second input channel to the output end to flow into the output channel. At the same time, after the second limiting component rotates, it abuts against the rotation limiting component. The rotation limiting component moves to the first limiting component and limits the rotation of the first limiting component. This ensures that during the process of the packaging box from the second input channel to the output end flowing into the output channel, the packaging box from the first input channel to the output end will be blocked by the first limiting component, so as to avoid multiple packaging boxes blocking the input end of the output channel.
[0014] In some embodiments, the first limiting component includes a first limiting rod and a first rotating member. The first limiting rod is connected to the first rotating member, the first rotating member is rotatably connected to the mounting base, and the first elastic reset member is disposed between the first rotating member and the mounting base. The first elastic reset member is used to drive the first rotating member to reset, and the first limiting rod extends in a direction away from the rotation axis of the first rotating member.
[0015] The second limiting component includes a second limiting rod and a second rotating member. The second limiting rod is connected to the second rotating member, which is rotatably connected to the mounting base. The rotation axis of the second rotating member is parallel to the rotation axis of the first rotating member. The second elastic reset member is disposed between the second rotating member and the mounting base. The second elastic reset member is used to drive the second rotating member to reset. The second limiting rod extends in a direction away from the rotation axis of the second rotating member. When both the first and second elastic reset members are reset, the first limiting rod and the second limiting rod form a preset angle.
[0016] With the above structure, the volume and mass of the first limiting rod are relatively small, making it easier to drive the first rotating component to rotate when the packaging box presses against the first limiting rod. This reduces the resistance of the first limiting rod to the packaging box when it presses against the first limiting rod, allowing the packaging box to smoothly enter the output channel from the first input channel.
[0017] In some embodiments, the one-way release structure further includes a third elastic reset member. A first limiting groove is provided on one side of the first rotating member, and a second limiting groove is provided on one side of the second rotating member. The rotating limiting assembly is rotatably connected to the mounting base. The third elastic reset member is disposed between the mounting base and the rotating limiting assembly. The third elastic reset member is used to drive the rotating limiting assembly to reset.
[0018] The rotation limiting component includes a first limiting block and a second limiting block. When both the first rotating member and the second rotating member are reset, the rotation limiting component is reset. The first limiting block is located in the first limiting groove, and the second limiting block is located in the second limiting groove.
[0019] When the first rotating member rotates, the groove wall of the first limiting groove abuts against the first limiting block, causing the rotation limiting assembly to rotate. The first limiting block moves out of the first limiting groove and abuts against the side surface of the first rotating member. When the second rotating member has a rotational tendency, the side surface of the first rotating member can rotate and limit the rotation of the rotation limiting assembly, so that the second limiting block abuts against the groove wall of the second limiting groove and limits the rotation of the second rotating member.
[0020] When the second rotating member rotates, the groove wall of the second limiting groove abuts against the second limiting block, causing the rotation limiting assembly to rotate. The second limiting block moves out of the second limiting groove and abuts against the side surface of the second rotating member. When the first rotating member has a rotational tendency, the side surface of the second rotating member can rotate and limit the rotation of the rotation limiting assembly, so that the first limiting block abuts against the groove wall of the first limiting groove and limits the rotation of the first rotating member.
[0021] With the above structure, when the packaging box moves to the output end of the first input channel, the packaging box can press against the first limiting rod, so that the first limiting component rotates relative to the mounting base, and the packaging box can enter the output channel. At the same time, the groove wall of the first limiting groove abuts against the first limiting block, and the first limiting block moves out of the first limiting groove and abuts against the side surface of the first rotating component. When another packaging box moves to the output end of the second input channel and presses against the second limiting rod, the second rotating component has a rotational tendency, and the side surface of the first rotating component can rotate and limit the rotation of the rotation limiting component, so that the second limiting block abuts against the groove wall of the second limiting groove and rotates and limits the second rotating component, so that the second limiting component can limit the packaging box at the output end of the second input channel.
[0022] In addition, when the packaging box moves to the output end of the second input channel, the packaging box can press against the second limiting rod, so that the second limiting component rotates relative to the mounting base, and the packaging box can enter the output channel. At the same time, the groove wall of the second limiting groove abuts against the second limiting block. The second limiting block moves out of the second limiting groove and abuts against the side surface of the second rotating component. When another packaging box moves to the output end of the first input channel and presses against the first limiting rod, the first rotating component has a rotation tendency. The side surface of the second rotating component can rotate and limit the rotation of the rotation limiting component, so that the first limiting block abuts against the groove wall of the first limiting groove and rotates and limits the first rotating component. This allows the first limiting component to limit the packaging box at the output end of the first input channel to avoid blockage at the intersection of the first input channel, the second input channel and the output channel.
[0023] In some embodiments, the rotation limiting assembly further includes a main body rotatably connected to the mounting base, a third elastic reset member disposed between the mounting base and the main body, and the third elastic reset member being used to drive the main body to reset; the first limiting block is rotatably connected to one end of the main body, and the second limiting block is rotatably connected to the other opposite end of the main body.
[0024] With the above structure, the first limiting block is rotatably connected to one end of the main body. When the groove wall of the first limiting groove abuts against the first limiting block, the first limiting block can more easily drive the main body to rotate. The second limiting block is rotatably connected to the other opposite end of the main body. When the groove wall of the second limiting groove abuts against the second limiting block, the second limiting block can more easily drive the main body to rotate.
[0025] In some embodiments, the walls of the first limiting groove and the second limiting groove are both curved surfaces, and in the horizontal direction, the walls of the first limiting groove and the second limiting groove are both arc-shaped.
[0026] With the above structure, both the first limiting block and the second limiting block are rotatably connected to the main body, and the groove walls of both the first limiting groove and the second limiting groove are curved surfaces. As a result, the first limiting block is more likely to detach from the first limiting groove after being subjected to force, and the second limiting block is also more likely to detach from the second limiting groove after being subjected to force. When one package is transported to the output end of the first input channel and at the same time, one package is transported to the output end of the second input channel. At the same time, one package abuts against the first limiting rod and the other package abuts against the second limiting rod. The first rotating part and the second rotating part rotate slightly. The groove wall of the first limiting groove abuts against the first limiting block, and at the same time, the groove wall of the second limiting groove abuts against the second limiting block. As a result, the main body is balanced by force, and both packages are blocked.
[0027] When the third package is delivered to the output end of the first input channel, the output end of the first input channel has two packages. The pressure of the two packages on the first limit rod increases, causing the first rotating component to rotate further. The groove wall of the first limit groove presses against the first limit block, causing the first limit block to move out of the first limit groove. At this time, the main body rotates further, and the second limit block presses against the groove wall of the second limit groove, causing the second rotating component to reset. The two packages at the output end of the first input channel can be preferentially delivered into the output channel to avoid blockage at the intersection of the first input channel, the second input channel and the output channel.
[0028] In some embodiments, the first elastic reset member includes a tension spring and two annular hooks, the two annular hooks being respectively connected to opposite ends of the tension spring; the first limiting member further includes a mounting strip, the mounting strip having a hanging hole, the mounting strip being connected to one side of the first rotating member, the hanging hole being located at the lower part of the first rotating member, one of the annular hooks being hung on the mounting base, and the other annular hook being hung on the hanging hole.
[0029] With the above structure, one ring hook is hung on the mounting base and the other ring hook is hung on the hanging hole, so that the first elastic reset member can be more stably connected between the mounting base and the first limiting member, so as to prevent the first elastic reset member from falling off relative to the first limiting member and also to prevent the first elastic reset member from falling off relative to the mounting base.
[0030] In some embodiments, the one-way release structure further includes a locking member; the first limiting member includes a first rotating shaft, which passes through the mounting base and is rotatably connected to the mounting base, and the first rotating shaft has a first insertion hole; the second limiting member includes a second rotating shaft, which passes through the mounting base and is rotatably connected to the mounting base, and the second rotating shaft has a second insertion hole.
[0031] When both the first and second elastic reset members are reset, the first insertion hole and the second insertion hole are aligned, and the locking member can be inserted into both the first insertion hole and the second insertion hole simultaneously.
[0032] With the above structure, when the transmission module is not in use or the output channel is suspended, the locking member can be inserted into the first and second plug holes simultaneously, so that neither the first nor the second rotating shaft can rotate, thereby locking the one-way release structure.
[0033] Another embodiment of this utility model provides a transmission module, including the one-way release structure in any of the above embodiments.
[0034] In some embodiments, the transmission module further includes a first input channel, a second input channel, and an output channel, wherein the output end of the first input channel, the output end of the second input channel, and the input end of the output channel intersect at one point, and the mounting base is fixed to the intersection of the output end of the first input channel, the output end of the second input channel, and the output channel;
[0035] When the first elastic reset member is reset, the first limiting member is located at the output end of the first input channel. When the rotation limiting component limits the rotation of the first limiting member, the output end of the first input channel is closed. When the second elastic reset member is reset, the second limiting member is located at the output end of the second input channel. When the rotation limiting component limits the rotation of the second limiting member, the output end of the second input channel is closed.
[0036] Another embodiment of this utility model provides a fruit and vegetable sorting device, including the transmission module in any of the above embodiments.
[0037] Compared to existing technologies, users can place packaging boxes for fruits and vegetables on the first and second input channels, which flow towards the output channel. When the packaging box moves to the output end of the first input channel, it presses against the first limiting component, causing the first limiting component to rotate relative to the mounting base. This allows the packaging box located at the output end of the first input channel to flow into the output channel. Simultaneously, after rotating, the first limiting component abuts against a rotation limiting component. The rotation limiting component then moves to the second limiting component and limits its rotation. This ensures that as the packaging box at the output end of the first input channel flows into the output channel, the packaging box at the output end of the second input channel is blocked by the second limiting component, preventing multiple packaging boxes from blocking the input end of the output channel.
[0038] In addition, when the packaging box moves to the output end of the second input channel, the packaging box can press against the second limiting component, so that the second limiting component rotates relative to the mounting base. Then, the packaging box located at the output end of the second input channel can flow into the output channel. At the same time, after the second limiting component rotates, it abuts against the rotation limiting component. The rotation limiting component moves to the first limiting component and limits the rotation of the first limiting component. So that during the process of the packaging box located at the output end of the second input channel flowing into the output channel, the packaging box located at the output end of the first input channel will be blocked by the first limiting component, so as to avoid multiple packaging boxes blocking the input end of the output channel.

[0048] 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.
[0049] The following description, in conjunction with all the accompanying drawings, details a one-way release structure 100, a transmission module 1000, and a fruit and vegetable sorting device provided in this application through specific embodiments.
[0050] Please refer to Figure 1 and Figure 2One embodiment of this utility model discloses a transmission module 1000, including a one-way release structure 100, a first input channel 200, a second input channel 300, and an output channel 400. The output ends of the first input channel 200, the second input channel 300, and the input ends of the output channel 400 intersect at one point. The one-way release structure 100 is located at the intersection of the output ends of the first input channel 200, the second input channel 300, and the output channel 400.
[0051] Another embodiment of this utility model discloses a one-way release structure 100, including a mounting base 10, a first limiting component 20, a second limiting component 30, and a rotation limiting component 40; the first limiting component 20 includes a first limiting member 22 and a first elastic reset member 24, the first limiting member 22 is rotatably connected to the mounting base 10, the first elastic reset member 24 is disposed between the first limiting member 22 and the mounting base 10, the first elastic reset member 24 is used to drive the first limiting member 22 to reset, and the first limiting member 22 extends in a direction away from the rotation axis of the first limiting member 22.
[0052] The second limiting component 30 includes a second limiting member 32 and a second elastic reset member 34. The second limiting member 32 is rotatably connected to the mounting base 10. The rotation axis of the second limiting member 32 is parallel to the rotation axis of the first limiting member 22. The second elastic reset member 34 is disposed between the second limiting member 32 and the mounting base 10. The second elastic reset member 34 is used to drive the second limiting member 32 to reset. The second limiting member 32 extends in a direction away from the rotation axis of the second limiting member 32. When both the first elastic reset member 24 and the second elastic reset member 34 are reset, the first limiting member 22 and the second limiting member 32 form a preset angle.
[0053] The rotation limiting assembly 40 is installed on the mounting base 10. When one of the first limiting component 22 and the second limiting component 32 rotates, it can abut against the rotation limiting assembly 40, so that the rotation limiting assembly 40 moves to the other and limits the rotation of the other.
[0054] Specifically, the mounting base 10 is fixed at the intersection of the output end of the first input channel 200, the output end of the second input channel 300, and the output channel 400. When the first elastic reset member 24 is reset, the first limiting member 22 is located at the output end of the first input channel 200. When the rotation limiting assembly 40 limits the rotation of the first limiting member 22, the output end of the first input channel 200 is closed. When the second elastic reset member 34 is reset, the second limiting member 32 is located at the output end of the second input channel 300. When the rotation limiting assembly 40 limits the rotation of the second limiting member 32, the output end of the second input channel 300 is closed.
[0055] With the above structure, users can place packaging boxes for fruits and vegetables on the first input channel 200 and the second input channel 300, from which the contents flow to the output channel 400. When the packaging box moves to the output end of the first input channel 200, it presses against the first limiting member 22, causing the first limiting member 22 to rotate relative to the mounting base 10. This allows the packaging box at the output end of the first input channel 200 to flow into the output channel 400. Simultaneously, after rotating, the first limiting member 22 abuts against the rotation limiting component 40, causing the rotation limiting component 40 to move to the second limiting member 32 and rotate to limit the second limiting member 32. This ensures that as the packaging box at the output end of the first input channel 200 flows into the output channel 400, the packaging box at the output end of the second input channel 300 is blocked by the second limiting member 32, preventing multiple packaging boxes from blocking the input end of the output channel 400.
[0056] Additionally, when the packaging box moves to the output end of the second input channel 300, the packaging box can press against the second limiting member 32, so that the second limiting member 32 rotates relative to the mounting base 10. This allows the packaging box located at the output end of the second input channel 300 to flow into the output channel 400. At the same time, after the second limiting member 32 rotates, it abuts against the rotation limiting component 40, causing the rotation limiting component 40 to move to the first limiting member 22 and rotate and limit the first limiting member 22. This ensures that during the process of the packaging box located at the output end of the second input channel 300 flowing into the output channel 400, the packaging box located at the output end of the first input channel 200 will be blocked by the first limiting member 22, so as to avoid multiple packaging boxes blocking the input end of the output channel 400.
[0057] Specifically, in this embodiment, the first input channel 200, the second input channel 300, and the output channel 400 can all be motor-driven conveyor belts. The conveying directions of the first input channel 200 and the second input channel 300 can be perpendicular to each other, and the conveying directions of the first input channel 200 and the output channel 400 are the same. The first input channel 200, the second input channel 300, and the output channel 400 are used to convey carriers of fruits and vegetables, such as fruit frames or packaging boxes. This embodiment uses a packaging box as an example for description.
[0058] Mounting base 10 can be a plate-shaped metal structure resembling a triangle. The lower surface of mounting base 10 can be screwed to the intersection of the output end of the first input channel 200, the output end of the second input channel 300, and the output channel 400. The upper surface of mounting base 10 is used for mounting the first limiting component 20, the second limiting component 30, and the rotation limiting component 40. The first limiting component 22 can have a rod-like structure. The rotation axis of the first limiting component 22 is located on one side of the output end of the first input channel 200. The first elastic reset component 24 is a tension spring. When the first elastic reset component 24 is reset, the first limiting component 22 is perpendicular to the conveying direction of the first input channel 200.
[0059] The second limiting member 32 can have a rod-like structure. The rotation axis of the second limiting member 32 is located on one side of the output end of the second input channel 300. The second elastic reset member 34 is a tension spring. When the second elastic reset member 34 is reset, the second limiting member 32 is perpendicular to the conveying direction of the second input channel 300. The rotation limiting assembly 40 can rotate relative to the mounting base 10. The rotation limiting assembly 40 can be partially embedded in the first limiting member 22 or partially embedded in the second limiting member 32 to limit the first limiting member 22 or the partially embedded second limiting member 32.
[0060] In other embodiments, the first input channel 200, the second input channel 300 and the output channel 400 may be arranged in other ways, such as the included angle between two adjacent channels being 120°; the mounting base 10 may also be of other structures, such as a block structure similar to a cuboid.
[0061] Please refer to Figure 3 In some embodiments, the first limiting component 22 includes a first limiting rod 222 and a first rotating component 224. The first limiting rod 222 is connected to the first rotating component 224, and the first rotating component 224 is rotatably connected to the mounting base 10. A first elastic reset component 24 is disposed between the first rotating component 224 and the mounting base 10. The first elastic reset component 24 is used to drive the first rotating component 224 to reset. The first limiting rod 222 extends in a direction away from the rotation axis of the first rotating component 224.
[0062] The second limiting component 32 includes a second limiting rod 322 and a second rotating component 324. The second limiting rod 322 is connected to the second rotating component 324, and the second rotating component 324 is rotatably connected to the mounting base 10. The rotation axis of the second rotating component 324 is parallel to the rotation axis of the first rotating component 224. The second elastic reset component 34 is disposed between the second rotating component 324 and the mounting base 10. The second elastic reset component 34 is used to drive the second rotating component 324 to reset. The second limiting rod 322 extends in a direction away from the rotation axis of the second rotating component 324. When both the first elastic reset component 24 and the second elastic reset component 34 are reset, the first limiting rod 222 and the second limiting rod 322 form a preset angle.
[0063] With the above structure, the first limiting rod 222 has a smaller volume and mass, making it easier to drive the first rotating part 224 to rotate when the packaging box presses against the first limiting rod 222. This reduces the resistance of the first limiting rod 222 to the packaging box when it presses against the first limiting rod 222, allowing the packaging box to smoothly enter the output channel 400 from the first input channel 200.
[0064] In addition, the second limiting rod 322 is smaller in size and mass, making it easier to drive the second rotating part 324 to rotate when the packaging box presses against the second limiting rod 322. This reduces the resistance of the second limiting rod 322 to the packaging box when it presses against the second limiting rod 322, allowing the packaging box to smoothly enter the output channel 400 from the second input channel 300.
[0065] Specifically, in this embodiment, the first limiting rod 222 includes a first sheet-like metal strip 2222 and a second sheet-like metal strip 2224. The first sheet-like metal strip 2222 is parallel to the horizontal plane and connected to the upper end of the first rotating member 224. The second sheet-like metal strip 2224 is connected to one side of the first sheet-like metal strip 2222 and located on the lower surface of the first sheet-like metal strip 2222. The second sheet-like metal strip 2224 is perpendicular to the horizontal plane. Both the first sheet-like metal strip 2222 and the second sheet-like metal strip 2224 extend in a direction away from the rotation axis of the first rotating member 224. The first sheet-like metal strip 2222 and the second sheet-like metal strip 2224 can improve the strength of the first limiting rod 222.
[0066] The first rotating member 224 can have a cylindrical structure and is hollow. One end of the first elastic reset member 24 is connected to the lower part of the first rotating member 224. The structure of the second limiting component 30 is the same as that of the first limiting component 20.
[0067] In other embodiments, the first limiting rod 222 and the second limiting rod 322 may also be other structures, such as a long cylindrical body parallel to the horizontal plane; the first rotating member 224 may also be other structures, such as a structure similar to a cuboid.
[0068] Please refer to Figure 4 In some embodiments, the one-way release structure 100 further includes a third elastic reset member 50. A first limiting groove 2242 is provided on one side of the first rotating member 224, and a second limiting groove 3242 is provided on one side of the second rotating member 324. The rotation limiting component 40 is rotatably connected to the mounting base 10. The third elastic reset member 50 is disposed between the mounting base 10 and the rotation limiting component 40. The third elastic reset member 50 is used to drive the rotation limiting component 40 to reset.
[0069] The rotation limiting assembly 40 includes a first limiting block 42 and a second limiting block 44. When both the first rotating member 224 and the second rotating member 324 are reset, the rotation limiting assembly 40 is reset, the first limiting block 42 is located in the first limiting groove 2242, and the second limiting block 44 is located in the second limiting groove 3242.
[0070] When the first rotating member 224 rotates, the groove wall of the first limiting groove 2242 abuts against the first limiting block 42, causing the rotation limiting assembly 40 to rotate. The first limiting block 42 moves out of the first limiting groove 2242 and abuts against the side surface of the first rotating member 224. When the second rotating member 324 has a rotational tendency, the side surface of the first rotating member 224 can limit the rotation of the rotation limiting assembly 40, so that the second limiting block 44 abuts against the groove wall of the second limiting groove 3242 and limits the rotation of the second rotating member 324.
[0071] When the second rotating member 324 rotates, the groove wall of the second limiting groove 3242 abuts against the second limiting block 44, causing the rotation limiting assembly 40 to rotate. The second limiting block 44 moves out of the second limiting groove 3242 and abuts against the side surface of the second rotating member 324. When the first rotating member 224 has a rotational tendency, the side surface of the second rotating member 324 can limit the rotation of the rotation limiting assembly 40, so that the first limiting block 42 abuts against the groove wall of the first limiting groove 2242 and limits the rotation of the first rotating member 224.
[0072] With the above structure, when the packaging box moves to the output end of the first input channel 200, the packaging box can press against the first limiting rod 222, so that the first limiting component 22 rotates relative to the mounting base 10, and the packaging box can enter the output channel 400. At the same time, the groove wall of the first limiting groove 2242 abuts against the first limiting block 42, and the first limiting block 42 moves out of the first limiting groove 2242 and abuts against the side surface of the first rotating component 224. When another packaging box moves to the output end of the second input channel 300 and presses against the second limiting rod 322, the second rotating component 324 has a rotational tendency. The side surface of the first rotating component 224 can rotate and limit the rotation of the rotation limiting component 40, so that the second limiting block 44 abuts against the groove wall of the second limiting groove 3242 and rotates and limits the second rotating component 324, so that the second limiting component 32 can limit the packaging box at the output end of the second input channel 300.
[0073] Additionally, when the packaging box moves to the output end of the second input channel 300, the packaging box can press against the second limiting rod 322, so that the second limiting component 32 rotates relative to the mounting base 10, and the packaging box can enter the output channel 400. At the same time, the groove wall of the second limiting groove 3242 abuts against the second limiting block 44, and the second limiting block 44 moves out of the second limiting groove 3242 and abuts against the side surface of the second rotating component 324. When another packaging box moves to the output end of the first input channel 200 and presses against the first limiting rod 222, the first rotating component 224 has a rotational tendency, and the side surface of the second rotating component 324 can rotate and limit the rotation of the rotation limiting component 40, so that the first limiting block 42 abuts against the groove wall of the first limiting groove 2242 and rotates and limits the first rotating component 224, so that the first limiting component 22 can limit the packaging box at the output end of the first input channel 200 to avoid blockage at the intersection of the first input channel 200, the second input channel 300 and the output channel 400.
[0074] Specifically, in this embodiment, the rotation limiting component 40 can be similar to a strip-shaped block structure. The first limiting block 42 and the second limiting block 44 are located on opposite sides of the rotation limiting component 40, and both the first limiting block 42 and the second limiting block 44 protrude above the rotation limiting component 40. The rotation axis of the rotation limiting component 40 is located in the middle of the rotation limiting component 40, and the lower end of the rotation axis of the rotation limiting component 40 is rotatably connected to the mounting base 10. The third elastic reset member 50 can be a torsion spring, and the third elastic reset member 50 can be sleeved on the rotation axis of the rotation limiting component 40.
[0075] In other embodiments, the rotation limiting component 40 may also have other structures, such as an arc-shaped strip structure; the first limiting block 42 and the second limiting block 44 may also be located on the side surface of the rotation limiting component 40.
[0076] In some embodiments, the rotation limiting assembly 40 further includes a main body 46, which is rotatably connected to the mounting base 10. A third elastic reset member 50 is disposed between the mounting base 10 and the main body 46, and the third elastic reset member 50 is used to drive the main body 46 to reset. A first limiting block 42 is rotatably connected to one end of the main body 46, and a second limiting block 44 is rotatably connected to the other opposite end of the main body 46.
[0077] With the above structure, the first limiting block 42 is rotatably connected to one end of the main body 46. When the groove wall of the first limiting groove 2242 abuts against the first limiting block 42, the first limiting block 42 can more easily drive the main body 46 to rotate. The second limiting block 44 is rotatably connected to the other opposite end of the main body 46. When the groove wall of the second limiting groove 3242 abuts against the second limiting block 44, the second limiting block 44 can more easily drive the main body 46 to rotate.
[0078] Specifically, both the first limiting block 42 and the second limiting block 44 can be cylinders. The central axes of the first limiting block 42 and the second limiting block 44 are perpendicular to the horizontal plane and parallel to the rotation axis of the first rotating member 224 and the rotation axis of the second rotating member 324.
[0079] In some embodiments, the groove walls of the first limiting groove 2242 and the second limiting groove 3242 are both curved surfaces, and in the horizontal direction, the groove walls of the first limiting groove 2242 and the second limiting groove 3242 are both arc-shaped.
[0080] With the above structure, the first limiting block 42 and the second limiting block 44 are both rotatably connected to the main body 46, and the groove walls of the first limiting groove 2242 and the second limiting groove 3242 are both curved surfaces. Therefore, the first limiting block 42 is more likely to detach from the first limiting groove 2242 after being subjected to force, and the second limiting block 44 is also more likely to detach from the second limiting groove 3242 after being subjected to force. When a package is transported to the output end of the first input channel 200 and at the same time a package is transported to the output end of the second input channel 300, one package abuts against the first limiting rod 222 and the other package abuts against the second limiting rod 322. The first rotating member 224 and the second rotating member 324 both rotate slightly. The groove wall of the first limiting groove 2242 abuts against the first limiting block 42, and at the same time the groove wall of the second limiting groove 3242 abuts against the second limiting block 44. Therefore, the main body 46 is balanced by force, and both packages are blocked.
[0081] When the third package is delivered to the output end of the first input channel 200, the output end of the first input channel 200 has two packages. The pressure of the two packages on the first limiting rod 222 increases, causing the first rotating member 224 to rotate further. The groove wall of the first limiting groove 2242 presses against the first limiting block 42, so as to drive the first limiting block 42 to move out of the first limiting groove 2242. At this time, the main body 46 rotates further, and the second limiting block 44 presses against the groove wall of the second limiting groove 3242, causing the second rotating member 324 to reset. The two packages at the output end of the first input channel 200 can be preferentially delivered into the output channel 400 to avoid blockage at the intersection of the first input channel 200, the second input channel 300 and the output channel 400.
[0082] Specifically, in a direction parallel to the horizontal plane, the wall of the first limiting groove 2242 can be arc-shaped, and the wall of the second limiting groove 3242 can also be arc-shaped.
[0083] Please see Figure 5 In some embodiments, the first elastic reset member 24 includes a tension spring member 242 and two annular hooks 244, which are respectively connected to opposite ends of the tension spring member 242; the first limiting member 22 also includes a mounting strip 226, which has a hanging hole 2262. The mounting strip 226 is connected to one side of the first rotating member 224, and the hanging hole 2262 is located at the lower part of the first rotating member 224. One annular hook 244 is hung on the mounting base 10, and the other annular hook 244 is hung in the hanging hole 2262.
[0084] With the above structure, one ring hook 244 is hung on the mounting base 10, and the other ring hook 244 is hung on the hanging hole 2262, so that the first elastic reset member 24 can be more stably connected between the mounting base 10 and the first limiting member 22, so as to prevent the first elastic reset member 24 from falling off relative to the first limiting member 22, and also to prevent the first elastic reset member 24 from falling off relative to the mounting base 10.
[0085] Specifically, the mounting strip 226 can be in the shape of a cuboid, the hanging hole 2262 can be a circular through hole that passes through the mounting strip 226, the central axis of the hanging hole 2262 is parallel to the horizontal plane, and there can be multiple hanging holes 2262. All the hanging holes 2262 are evenly distributed on the mounting strip 226 from top to bottom, and the annular hook 244 is hung on the hanging hole 2262 located at the bottom of the mounting strip 226.
[0086] In some embodiments, the device further includes a locking member 60. The first limiting member 22 includes a first rotating shaft 228, which passes through the mounting base 10 and is rotatably connected to the mounting base 10. The first rotating shaft 228 has a first insertion hole 2282. The second limiting member 32 includes a second rotating shaft 326, which passes through the mounting base 10 and is rotatably connected to the mounting base 10. The second rotating shaft 326 has a second insertion hole 3262.
[0087] When both the first elastic reset member 24 and the second elastic reset member 34 are reset, the first insertion hole 2282 and the second insertion hole 3262 are aligned, and the locking member 60 can be inserted into the first insertion hole 2282 and the second insertion hole 3262 at the same time.
[0088] With the above structure, when the transmission module 1000 is not in use, or when the output channel 400 is suspended, the locking member 60 can be inserted into the first insertion hole 2282 and the second insertion hole 3262 at the same time, so that the first rotating shaft 228 and the second rotating shaft 326 cannot rotate, thereby locking the one-way release structure 100.
[0089] Specifically, the locking member 60 can be a bolt. After the locking member 60 is inserted into the first insertion hole 2282 and the second insertion hole 3262, the end of the locking member 60 can be connected to the nut by threads so that the locking member 60 is fixed relative to the first rotating shaft 228 and the second rotating shaft 326.
