Description

Technical Field

[0001] This invention relates to the field of jujube sorting equipment technology, specifically a feeding and sorting mechanism for a visual intelligent jujube sorting machine. Background Technology

[0002] The jujube visual intelligent sorting machine integrates optical, mechanical, electronic and computer technologies. The technical modules include: feeding and sorting mechanism, visual inspection system, grading execution mechanism and control and data processing. It can quickly and accurately sort jujubes without damage. The feeding and sorting mechanism is the throat of the entire sorting system. It feeds the piled-up and disorderly jujubes into the visual inspection area in a single, oriented and evenly spaced manner. The common feeding method often uses multiple rotating rollers, allowing the jujubes to fall between two rotating rollers. Then, the conveyor belt drives the rotating rollers to move, thereby moving the jujubes. The rotation of the rotating rollers also causes the jujubes to rotate, making it easier for the visual detector to observe the state of the jujubes.

[0003] When jujubes fall towards the rotating roller, the roller's movement speed is often faster than the jujubes' falling speed. When the rotating roller moves the jujubes, the instantaneous speed difference will cause the subsequent jujubes to have spacing. When the jujubes come into contact with the fast-moving rotating roller, they may bounce. Some jujubes with more moisture are more elastic and may bounce multiple times. When they fall and come into contact with the rotating roller again, they may bounce multiple times. The bounced jujubes may fall between two unexpected rotating rollers, which may form two parallel or overlapping jujubes. This may cause the visual detector to misjudge the shape of the jujubes and affect the sorting of the jujubes. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a feeding and sorting mechanism for a jujube visual intelligent sorting machine, including a conveyor and a support platform. A visual inspection instrument is fixedly connected to the top of the support platform, four blowing sorting machines are fixedly connected to the top of the support platform, and a separator is fixedly connected to the top of the support platform.

[0005] The main mechanism is rotatably mounted on the inner wall of the support platform and is used to sort red dates;

[0006] A compression mechanism is fixedly mounted on the top of the support platform and is used to compress gas;

[0007] The blocking mechanism is fixedly installed on the inner wall of the divider to block the jumping dates.

[0008] The process involves pouring the dates into a conveyor, which then moves them toward a support platform. The main structure then transports the dates to a vision inspection device, which captures images of the rotating dates and transmits them to a computer for processing and analysis. This process identifies surface defects such as cracks, blemishes, and uneven coloring. Finally, the dates are sorted using a blower.

[0009] Preferably, the main structure includes:

[0010] The drive assembly is rotatably mounted on the inner wall of the support platform via a rotating component.

[0011] The rotating component includes two rotating rods rotatably connected to the inner wall of the support platform, and two conveyor belts are provided on the inner wall of the support platform;

[0012] The conveying assembly is fixedly mounted on top of the conveyor belt by fasteners;

[0013] The fasteners include several fixed sleeves fixedly connected to the outer wall of the conveyor belt, and several rotating rollers are provided on the side wall of the support platform;

[0014] The jujubes transported by the conveyor will fall onto the top of the conveyor assembly. The drive assembly is activated to rotate the conveyor assembly, thereby transporting the jujubes toward the vision inspection instrument.

[0015] Preferably, the compression mechanism includes:

[0016] Storage components are fixedly mounted on the top of the support platform via connectors;

[0017] The connector includes a pneumatic frame fixedly connected to the top of the support platform, and an air pump fixedly connected to the back of the support platform.

[0018] The jet assembly is fixedly mounted on the side wall of the pneumatic frame by a support member;

[0019] The support structure includes eighteen solenoid valves that are connected through the inner wall of the pneumatic frame;

[0020] Preferably, high-pressure gas is generated by starting an air pump and enters the air pressure frame to store the high-pressure gas.

[0021] Preferably, the blocking mechanism includes:

[0022] The damping component is fixedly installed on the inner wall of the partition frame by a limiting member;

[0023] The limiting components include a fixing rod that is fixedly connected to the inner wall of the partition frame, and eighteen inclined baffles are provided on the top of the support platform;

[0024] The diversion component is slidably disposed on the inner wall of the inclined baffle.

[0025] When the jujube bounces and comes into contact with the deceleration component, it will block the jujube. At the same time, the gas ejected by the jet component will push the jujube to fall again, limiting the jujube's bounce.

[0026] Preferably, the drive assembly includes a motor fixedly connected to the back of the support platform, the output end of the motor being fixedly connected to the back of a rotating rod located on the left side, and the outer walls of both rotating rods being rotatably connected to the inner walls of the two conveyor belts.

[0027] The starter motor drives the rotating rod located on the left to rotate, which in turn drives the conveyor belt to rotate.

[0028] Preferably, the conveying assembly includes gears fixedly connected to the front of several rotating rollers, and the inner walls of the several rotating rollers are rotatably connected to the inner walls of several fixed sleeves.

[0029] A rack is fixedly connected to the inner wall of the support platform, and the top of the rack meshes with the outer wall of several gears.

[0030] As the conveyor belt rotates, multiple fixed sleeves and rotating rollers move towards the vision inspection instrument. During this movement, the rotating rollers drive the gears and racks to mesh, causing the gears to rotate clockwise and drive the rotating rollers to rotate. The dates conveyed by the conveyor eventually fall between the two rotating rollers and are separated by a separator. Because the rotating rollers move at a high speed, they cause the dates to move quickly, and the resulting instantaneous speed difference increases the distance between the dates. In addition, the rotating rollers rotate, and the dates located between the two rotating rollers are affected by friction, causing them to rotate as well.

[0031] As the rotating rollers continue to move, they will move the jujubes to the position of the vision inspection device. The vision inspection device will capture images of the rotating jujubes and transmit them to the computer for processing and analysis. It will identify surface defects such as cracks, bad spots, and uneven color, and output judgment signals to multiple blow-test sorting machines. When the jujubes move to the position of the blow-test sorting machine that sorts different defects, the blow-test sorting machine will start and blow the jujubes into the sorting channel to complete the sorting of the jujubes.

[0032] Preferably, the storage component includes an air supply pipe that is connected through to the side wall of the air pressure frame, the top output end of the air pump is connected through to the bottom of the air supply pipe, and a spring ball joint is slidably connected to the inner wall of the air supply pipe.

[0033] The process involves starting the air pump to generate high-pressure gas, which then enters the gas delivery pipe. This pushes the spring ball joint to separate from the inclined surface of the gas delivery pipe, allowing the high-pressure gas to enter the air pressure frame and be stored.

[0034] Preferably, the jet assembly includes a jet pipe that is connected through to the inner wall of the solenoid valve, and eighteen inclined jet frames are fixedly connected to the inner wall of the separator, with the inner walls of the eighteen inclined jet frames all being connected through to the outer walls of the eighteen jet pipes.

[0035] Preferably, the mitigation assembly includes eighteen inclined baffles fixedly connected to the inner wall of the partition frame, the inner walls of the eighteen inclined baffles being rotatably connected to the outer wall of the fixed rod, and sensors being fixedly connected to the top of the eighteen inclined baffles.

[0036] When a jujube with strong elasticity comes into contact with the rapidly moving rotating roller and bounces, the rotating roller moves towards the vision inspection instrument and rotates clockwise, giving the jujube a force to the right, causing it to bounce to the right. When the bouncing jujube comes into contact with the inclined baffle, it pushes the inclined baffle to rotate. After the inclined baffle rotates, the sensor will detect the change in the position of the inclined baffle and transmit a signal through the sensor to briefly open the solenoid valve.

[0037] The gas inside the air pressure frame enters the jet pipe, then flows into the inclined jet frame. It is then sprayed out along the slope of the inclined baffle towards the jujubes, causing them to move towards the rotating rollers. As the jujubes fall, they bounce again upon contact with the rotating rollers. Because the jujubes tend to bounce to the right, they are blocked by the bottom of the diverting component, limiting their bounce. Finally, the jujubes land between the two rotating rollers, where they are moved further. Jujubes near the separator contact the inclined surface of the guide plate, guiding them towards the center of the rotating rollers. By limiting the bounce and ensuring the jujubes are positioned in the center, this process effectively prevents large bounces and positional changes that could occur when the jujubes contact the rapidly moving rollers. Overlapping or paralleling of jujubes between the rollers could cause the visual inspection instrument to misjudge their shape, affecting the sorting process.

[0038] Preferably, the diversion assembly includes two flow channels formed on the inner wall of the inclined baffle, eighteen blocks are slidably connected to the inner wall of the separator, the top of each of the eighteen blocks is fixedly connected to a sliding rod, and the outer wall of each of the eighteen sliding rods is slidably connected to the inner wall of the inclined baffle.

[0039] When the jujube bounces again upon contact with the rotating roller, it will come into contact with the bottom of the stop block. The stop block will block the jujube. When airflow is ejected from the inclined jet frame, some of the airflow will flow along the inclined surface of the baffle. The airflow will enter the two guide channels and flow between the baffle and the bottom of the inclined baffle, splitting the airflow into multiple streams. This will reduce the thrust of the subsequent airflow on the jujube after the jujube moves away from the inclined jet frame, effectively preventing the jujube from falling back into contact with the rotating roller. The subsequent strong airflow would have a strong impact on the jujube, which may cause the jujube to fall horizontally between the two rotating rollers, affecting the jujube's rotation and making it difficult for the visual inspection instrument to fully identify the overall shape of the jujube.

[0040] The present invention has the following beneficial effects:

[0041] (1) In this invention, the jujubes are moved by starting a conveyor, and then the jujubes are moved to the position of the vision inspection instrument by the drive component and the conveying component. The vision inspection instrument is then started to capture images of the jujubes. Finally, the jujubes are sorted by a blower. After that, the air pump is started to generate high-pressure gas, which is introduced into the air pressure frame through the air pipe. When the fresh jujubes with strong elasticity come into contact with the fast-moving rotating roller, they bounce. The bouncing jujubes will push the inclined baffle to rotate. The sensor transmits a signal to briefly open the solenoid valve. The gas inside the air pressure frame enters the inclined air jet frame through the jet pipe and is sprayed out towards the jujubes along the inclined baffle. This causes the jujubes to move towards the rotating rollers. As the jujubes fall, they are blocked by the bottom of the diversion component, limiting their jumping and ensuring that each jujube is placed between the two rotating rollers. This effectively prevents the jujubes from jumping too much when they come into contact with the rapidly moving rotating rollers, which could change their position and cause the jujubes between the two rotating rollers to overlap or run parallel. This could lead to the visual inspection instrument misjudging the shape of the jujubes and affecting the sorting of the jujubes.

[0042] (2) When the jujube bounces again when it comes into contact with the rotating roller, it will come into contact with the bottom of the baffle. The baffle blocks the jujube. When the airflow is sprayed out from the inclined jet frame, some of the airflow will flow along the inclined surface of the baffle. The airflow will enter the two guide grooves and flow between the baffle and the bottom of the inclined baffle, splitting the airflow into multiple streams. After the jujube moves away from the inclined jet frame, the thrust of the subsequent airflow on the jujube is reduced, which effectively prevents the jujube from falling down and coming into contact with the rotating roller again. The subsequent strong airflow will have a strong impact on the jujube, which may cause the jujube to fall horizontally between the two rotating rollers, affecting the rotation of the jujube and making it difficult for the visual inspection instrument to fully identify the overall shape of the jujube.

[0043] (3) The present invention diverts the gas through the guide channel, which reduces the thrust of the airflow on the inclined baffle. At the same time, when some airflow flows in the guide channel, it will exert a downward squeezing force on the inclined baffle, which effectively prevents the gas from being ejected from the inclined baffle and causing the inclined baffle to rotate too much, which would easily lead to the inclined baffle returning to its original position and making it difficult to block the next jujube from jumping in time.

[0044] (4) When part of the airflow flows at the top of the baffle, the jujube is pushed by the airflow to the bottom of the baffle. When the jujube bounces and contacts the baffle again, it will push the baffle to rise. The airflow at the top of the baffle will increase the resistance of the baffle to rise, thereby increasing the resistance of the jujube to move upward, consuming the kinetic energy of the jujube, reducing the number of times the jujube bounces again, and effectively preventing the jujube from bouncing multiple times between the baffle and the rotating roller, which can easily cause damage to the surface of the jujube.

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Example 1, please refer to Figures 1-7 The present invention is a feeding and sorting mechanism for a jujube visual intelligent sorting machine, including a conveyor 13 and a support platform 14. A visual inspection instrument 15 is fixedly connected to the top of the support platform 14, four blow-testing sorting machines 16 are fixedly connected to the top of the support platform 14, and a separator 17 is fixedly connected to the top of the support platform 14. The specific model of the visual inspection instrument 15 is Teledyne DALSA.

[0059] Main mechanism 1 is rotatably mounted on the inner wall of support platform 14 for sorting red dates;

[0060] Compression mechanism 2 is fixedly installed on the top of support platform 14 and is used to compress gas;

[0061] The blocking mechanism 3 is fixedly installed on the inner wall of the partition frame 17 to block the jumping red dates.

[0062] The process involves pouring the jujubes to be sorted into the conveyor 13, then starting the conveyor 13 to move the jujubes toward the support platform 14, and then conveying the jujubes to the position of the vision inspection instrument 15 through the main body mechanism 1. The vision inspection instrument 15 then captures images of the rotating jujubes and transmits them to the computer for processing and analysis to identify surface defects such as cracked fruit, bad spots, and uneven color. Finally, the jujubes are sorted by the blow-testing sorting machine 16.

[0063] Main body 1 includes:

[0064] Drive assembly 11 is rotatably mounted on the inner wall of support platform 14 via a rotating component;

[0065] The rotating component includes two rotating rods 111 rotatably connected to the inner wall of the support platform 14, and two conveyor belts 113 are provided on the inner wall of the support platform 14;

[0066] Conveying assembly 12 is fixedly mounted on top of conveyor belt 113 by fasteners;

[0067] The fasteners include several fixed sleeves 121 fixedly connected to the outer wall of the conveyor belt 113, and several rotating rollers 122 are provided on the side wall of the support platform 14.

[0068] The red dates conveyed by the conveyor 13 will fall onto the top of the conveyor assembly 12. The drive assembly 11 will be activated to rotate the conveyor assembly 12, thereby conveying the red dates toward the vision inspection instrument 15.

[0069] Compression mechanism 2 includes:

[0070] Storage component 21 is fixedly mounted on the top of support platform 14 via connectors;

[0071] The connector includes a pneumatic frame 211 fixedly connected to the top of the support platform 14, and an air pump 212 fixedly connected to the back of the support platform 14. The specific model of the air pump 212 is: OX-0.66 / 8.

[0072] The jet assembly 22 is fixedly mounted on the side wall of the pneumatic frame 211 by a support member;

[0073] The support components include eighteen solenoid valves 222 that are connected through the inner wall of the pneumatic frame 211. The specific model of the solenoid valve 222 is ZBF22Q-6.

[0074] High-pressure gas is generated by activating air pump 212 and enters air pressure frame 211 to store high-pressure gas.

[0075] The blocking mechanism 3 includes:

[0076] The damping component 31 is fixedly installed on the inner wall of the partition frame 17 by a limiting member;

[0077] The limiting component includes a fixing rod 311 fixedly connected to the inner wall of the partition frame 17, and eighteen inclined baffles 312 are provided on the top of the support platform 14;

[0078] Diverting component 32 is slidably disposed on the inner wall of inclined baffle 312;

[0079] When the jujube bounces and comes into contact with the slowing component 31, it will block the jujube. At the same time, the gas ejected by the jet component 22 will push the jujube to fall again, thus limiting the bouncing of the jujube.

[0080] Example 2, please refer to Figures 3-9 The present invention is a feeding and sorting mechanism for a jujube visual intelligent sorting machine. Based on Example 1, the driving component 11 includes a motor 112 fixedly connected to the back of the support platform 14. The output end side wall of the motor 112 is fixedly connected to the back of the rotating rod 111 located on the left side. The outer walls of the two rotating rods 111 are rotatably connected to the inner walls of the two conveyor belts 113.

[0081] The starter motor 112 drives the rotating rod 111 located on the left to rotate, thereby driving the conveyor belt 113 to rotate.

[0082] The conveying assembly 12 includes gears 123 fixedly connected to the front of a plurality of rotating rollers 122, and the inner walls of the plurality of rotating rollers 122 are rotatably connected to the inner walls of a plurality of fixed sleeves 121.

[0083] A rack 124 is fixedly connected to the inner wall of the support platform 14, and the top of the rack 124 is meshed with the outer wall of several gears 123.

[0084] As the conveyor belt 113 rotates, multiple fixed sleeves 121 and rotating rollers 122 are conveyed to move towards the vision inspection instrument 15. During the movement, the rotating rollers 122 drive the gears 123 and racks 124 to contact and mesh. The gears 123 rotate clockwise during the movement, causing the rotating rollers 122 to rotate. The red dates conveyed by the conveyor 13 will eventually fall between the two rotating rollers 122 and be separated by the separator 17. Because the rotating rollers 122 move at a high speed, they will cause the red dates to move quickly. The instantaneous speed difference will increase the distance between the red dates. The rotating rollers 122 will also rotate. The red dates located between the two rotating rollers 122 will be affected by friction and will rotate.

[0085] As the rotating roller 122 continues to move, it will move the jujubes to the position of the vision inspection instrument 15. The vision inspection instrument 15 will capture images of the rotating jujubes and transmit them to the computer for processing and analysis. It will identify surface defects such as cracked fruit, bad spots, and uneven color, and output judgment signals to multiple blow-sorting machines 16. When the jujubes move to the position of the blow-sorting machine 16 that sorts different defects, the blow-sorting machine 16 will start and blow the jujubes into the sorting channel to complete the sorting of the jujubes.

[0086] The storage component 21 includes an air supply pipe 213 that is connected through to the side wall of the air pressure frame 211, the top output end of the air pump 212 is connected through to the bottom of the air supply pipe 213, and a spring ball joint rod 214 is slidably connected to the inner wall of the air supply pipe 213.

[0087] The process involves starting the air pump 212 to generate high-pressure gas, which enters the gas delivery pipe 213 and pushes the spring ball head rod 214 to separate from the inclined surface of the gas delivery pipe 213, allowing the high-pressure gas to enter the air pressure frame 211 for storage.

[0088] The jet assembly 22 includes a jet pipe 221 that is connected through the inner wall of the solenoid valve 222. Eighteen inclined jet frames 223 are fixedly connected to the inner wall of the partition frame 17. The inner walls of the eighteen inclined jet frames 223 are all connected through the outer walls of the eighteen jet pipes 221.

[0089] The mitigation assembly 31 includes eighteen inclined baffles 313 fixedly connected to the inner wall of the partition frame 17. The inner walls of the eighteen inclined baffles 312 are rotatably connected to the outer wall of the fixed rod 311. The top of each of the eighteen inclined baffles 313 is fixedly connected to a sensor 314. The specific model of the sensor 314 is GP1S50.

[0090] When a jujube with strong elasticity comes into contact with the rapidly moving rotating roller 122 and bounces, the rotating roller 122 moves towards the vision detector 15 and rotates clockwise, giving the jujube a force to the right, causing it to bounce to the right. When the bouncing jujube comes into contact with the inclined baffle 312, it pushes the inclined baffle 312 to rotate. After the inclined baffle 312 rotates, the sensor 314 will sense the change in the position of the inclined baffle 312 and transmit a signal through the sensor 314 to briefly open the solenoid valve 222.

[0091] The gas inside the air pressure frame 211 enters the jet pipe 221, then flows through the jet pipe 221 into the inclined jet frame 223. It is then sprayed out along the inclined surface of the inclined baffle 312 towards the jujubes, causing them to move towards the rotating roller 122 and fall. When the falling jujubes come into contact with the rotating roller 122 again, they bounce. Because the jujubes bounce to the right, they are blocked by the bottom of the diverting component 32, limiting their bounce. Finally, the jujubes fall between the two rotating rollers 122, causing the rotating rollers 122 to move them closer to the separator. The jujubes at position 17 will come into contact with the inclined surface of the inclined guide plate 313, guiding them towards the middle position of the rotating roller 122. By limiting the bouncing of the jujubes and ensuring that they are positioned in the middle of the rotating roller 122, this effectively prevents large bouncing amplitudes when the jujubes come into contact with the rapidly moving rotating roller 122, which could change the position of the jujubes and cause them to overlap or run parallel between the two rotating rollers 122. This could lead to the vision inspection instrument 15 misjudging the shape of the jujubes and affecting the sorting of the jujubes.

[0092] The diversion assembly 32 includes two guide channels 321 opened on the inner wall of the inclined baffle 312, eighteen blocks 322 are slidably connected to the inner wall of the separator 17, and a sliding rod 323 is fixedly connected to the top of each of the eighteen blocks 322. The outer walls of the eighteen sliding rods 323 are slidably connected to the inner wall of the inclined baffle 312.

[0093] When the jujube bounces again upon contact with the rotating roller 122, it will come into contact with the bottom of the stop block 322. The stop block 322 blocks the jujube. When airflow is ejected from the inclined jet frame 223, some of the airflow will flow along the inclined surface of the inclined baffle 312. The airflow will enter the two guide grooves 321 and flow between the stop block 322 and the bottom of the inclined baffle 312, splitting the airflow into multiple streams. This reduces the thrust of the subsequent airflow on the jujube after the jujube moves away from the inclined jet frame 223, effectively preventing the jujube from falling again and contacting the rotating roller 122. The subsequent strong airflow would then have a strong impact on the jujube, potentially causing it to fall laterally between the two rotating rollers 122. Figure 9 As shown in the position of G, it affects the rotation of the jujube, making it difficult for the visual inspection instrument 15 to fully identify the overall shape of the jujube.

[0094] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0095] A specific application of this embodiment is as follows: When using this invention, the red dates to be sorted are poured into the conveyor 13. Then, the conveyor 13 is started to transport the red dates toward the support platform 14. At the same time, the motor 112 is started to drive the rotating rod 111 on the left to rotate, thereby driving the conveyor belt 113 to rotate and transport multiple fixed sleeves 121 and rotating rollers 122 toward the vision inspection instrument 15. During the movement, the rotating rollers 122 will drive the gears 123 and racks 124 to contact and mesh. The gears 123 will rotate clockwise during the movement, causing the rotating rollers 122 to rotate. The red dates transported by the conveyor 13 will finally fall between the two rotating rollers 122 and be separated by the separator 17. Since the rotating rollers 122 move at a relatively fast speed, they will drive the red dates to move quickly. The instantaneous speed difference will increase the distance between the red dates. The rotating rollers 122 will also rotate. The red dates located between the two rotating rollers 122 will be affected by friction and will rotate.

[0096] As the rotating roller 122 continues to move, it will drive the jujubes to the position of the vision inspection instrument 15. The vision inspection instrument 15 will capture the image of the rotating jujubes and transmit it to the computer for processing and analysis. It will identify surface defects such as cracked fruit, bad spots, and uneven color, and output judgment signals to multiple blow-sorting machines 16. When the jujubes move to the position of the blow-sorting machine 16 that sorts different defects, the blow-sorting machine 16 will start and blow the jujubes into the sorting channel to complete the sorting of the jujubes.

[0097] Simultaneously, the air pump 212 is activated to generate high-pressure gas, which enters the gas delivery pipe 213, pushing the spring ball head rod 214 to separate from the inclined surface of the gas delivery pipe 213, removing the obstruction to the gas, and allowing the high-pressure gas to enter the air pressure frame 211 to store the high-pressure gas. When the jujube with strong elasticity comes into contact with the rapidly moving rotating roller 122 and bounces, the rotating roller 122 moves towards the vision detector 15 and also rotates clockwise, giving the jujube a force to the right, causing the jujube to bounce to the right. When the bouncing jujube comes into contact with the inclined baffle 312, it will push the inclined baffle 312 to rotate. After the inclined baffle 312 rotates, the sensor 314 will sense the change in the position of the inclined baffle 312 and transmit a signal through the sensor 314 to briefly open the solenoid valve 222.

[0098] The gas inside the air pressure frame 211 enters the jet pipe 221, then flows through the jet pipe 221 into the inclined jet frame 223. It is then sprayed out along the inclined surface of the inclined baffle 312 towards the jujubes, causing them to move towards the rotating roller 122 and fall. When the falling jujubes come into contact with the rotating roller 122 again, they bounce. Because the jujubes bounce to the right, they are blocked by the bottom of the diverting component 32, limiting their bounce. Finally, the jujubes fall between the two rotating rollers 122, causing the rotating rollers 122 to move them closer to the separator. The jujubes at position 17 will come into contact with the inclined surface of the inclined guide plate 313, guiding them towards the middle position of the rotating roller 122. By limiting the bouncing of the jujubes and ensuring that they are positioned in the middle of the rotating roller 122, this effectively prevents large bouncing amplitudes when the jujubes come into contact with the rapidly moving rotating roller 122, which could change the position of the jujubes and cause them to overlap or run parallel between the two rotating rollers 122. This could lead to the vision inspection instrument 15 misjudging the shape of the jujubes and affecting the sorting of the jujubes.

[0099] Secondly, when the jujubes bounce again upon contact with the rotating roller 122, they will come into contact with the bottom of the stop block 322. The stop block 322 blocks the jujubes. When airflow is ejected from the inclined jet frame 223, some of the airflow will flow along the inclined surface of the inclined baffle 312. The airflow will enter the two guide channels 321 and flow between the stop block 322 and the bottom of the inclined baffle 312, splitting the airflow into multiple streams. This keeps the jujubes away from the inclined jet frame 223, reducing the subsequent airflow's thrust on the jujubes and effectively preventing the jujubes from falling back into contact with the rotating roller 122. In such cases, the subsequent strong airflow would have a strong impact on the jujubes, potentially causing them to fall laterally between the two rotating rollers 122. Figure 9 As shown in the position of G, it affects the rotation of the jujube, making it difficult for the visual inspection instrument 15 to fully identify the overall shape of the jujube;

[0100] Secondly, by diverting the gas through the guide channel 321, the thrust of the airflow on the inclined baffle 312 will be reduced. At the same time, when some airflow flows in the guide channel 321, it will exert a downward squeezing force on the inclined baffle 312, which effectively prevents the inclined baffle 312 from rotating too much when the gas is ejected from the inclined surface of the inclined baffle 312. This would easily cause the inclined baffle 312 to return to its original position with lag, making it difficult to stop the next jujube from jumping in time.

[0101] Secondly, when some airflow flows at the top of the baffle 322, the jujube is pushed by the airflow to the bottom of the baffle 322. When the jujube comes into contact with the rotating roller 122 again and bounces, it will push the baffle 322 upward. The airflow that flows at the top of the baffle 322 will increase the resistance of the baffle 322 to rise, thereby increasing the resistance of the jujube to move upward, consuming the kinetic energy of the jujube, reducing the number of times the jujube bounces again, and effectively preventing the jujube from bouncing multiple times between the baffle 322 and the rotating roller 122, which could easily cause damage to the surface of the jujube.

[0102] The solenoid valve 222 opens briefly and then closes, causing the airflow that pushes the jujubes to disappear. Since the center of gravity of the inclined baffle 312 is close to the bottom, it will rotate back to its original position due to its own weight.
