Description

Technical Field

[0002] In the egg production and sales industry chain, egg freshness testing is crucial. Traditional egg freshness testing methods mainly rely on manual experience, such as observing the appearance of eggs, shaking eggs and listening to sounds. However, these manual testing methods have many limitations.

The method of shaking eggs and listening to the sound is highly subjective, and the judgment standards of different inspectors vary greatly, resulting in poor accuracy and consistency of test results. Moreover, manual inspection is inefficient. In large-scale egg processing scenarios, such as large chicken farms or egg processing companies, it requires a lot of manpower and time costs, and cannot meet the needs of rapid production and circulation.

[0004] With the continuous improvement of consumers' requirements for food safety and quality, as well as the advancement of the scale and automation development trend of the egg industry, there is an urgent need for an efficient, accurate and non-destructive egg freshness detection technology. Non-destructive testing can accurately judge the freshness of eggs without destroying the physical structure and internal components of eggs, which not only ensures that the quality of eggs is not affected, but also provides a reliable basis for subsequent classification, storage, sales and processing.

[0030] Example:

[0031] Please see attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a non-destructive detection device for egg freshness, such as Figure 1 As shown, the base 1 includes a base 1, which serves as the basic support part of the entire device. A round table 3 is fixedly installed on the middle part of the top through a column 2. The round table 3 is a core component around which various mechanisms are distributed. A loading mechanism 4 is provided on the left side of the round table 3 for completing egg loading. A cleaning mechanism 5 is provided on the rear side of the round table 3 for cleaning the eggs. A detection mechanism 6 is provided on the right side of the round table 3 for detecting the freshness of the eggs. A discharging mechanism 7 is provided on the front side of the round table 3 for discharging the eggs.

[0032] In this embodiment, a rotating shaft 8 is movably installed in the middle of the top of the truncated table 3, and the rotating shaft 8 can rotate flexibly at the top of the truncated table 3. A plurality of bending brackets 9 are fixedly installed on the top of the rotating shaft 8, and the bending brackets 9 play a connecting and supporting role. The ends of the rotating shafts 8 are fixedly installed with annular frames 10, and the middle of the annular frames 10 are movably installed with egg trays 11. The egg trays 11 are the key parts for placing eggs. The middle of the egg trays 11 are fixedly installed with photoelectric switches 12. The photoelectric switches 12 can be used to detect whether the eggs are placed in place and other related signal feedback. The bottom of the egg trays 11 is fixedly connected with aluminum rods 13 made of aluminum.

[0033] Furthermore, a first motor 14 is fixedly installed on the left side of the top of the truncated table 3. The first motor 14 is one of the power sources, and a driving bevel gear 15 is fixedly installed on its driving end. A driven bevel gear 16 is fixedly installed on the lower outer diameter of the rotating shaft 8, and the driven bevel gear 16 and the inner side end of the driving bevel gear 15 are meshed and connected. The driving bevel gear 15 is driven to rotate by the first motor 14, which drives the driven bevel gear 16 and the rotating shaft 8 to rotate, thereby driving all the bending brackets 9 and the egg tray 11 to rotate and move, which is convenient for subsequent loading work and at the same time, the eggs are sent into the cleaning mechanism 5.

[0034] Furthermore, the cleaning mechanism 5 includes a cleaning liquid storage tank 501, which is fixedly installed on the rear side of the top of the truncated table 3 and is used to store cleaning liquid. The bottom ends of the cleaning liquid storage tank 501 are fixedly connected to cylinders 502 on both sides, and pistons 506 are movably installed inside the cylinders 502. A first transmission rod 507 is movably installed on the rear side of the top of the base 1, and a cylinder 508 is fixedly installed on the top of the first transmission rod 507. The outer diameter of the cylinder 508 is provided with an inclined ball groove and the ball groove is provided with a piston 506. An inclined bearing seat 509 is movably installed, and both ends of the inclined bearing seat 509 are fixedly connected with a swing rod 510. The ends of the swing rod 510 are movably installed with a connecting rod 511. The ends of the connecting rod 511 are movably installed at the bottom of the corresponding side piston 506. When the second motor 517 is started, the second motor 517 drives the main shaft 518 to rotate, driving the first worm 519 to rotate. The rotating first worm 519 drives the first transmission rod 507 and the top cylinder 508 to rotate through meshing transmission. There is a certain angle between the ball groove on the outer diameter of 508 and the central axis of the cylinder body 508. When the cylinder body 508 rotates, it will drive the two sides of the oblique bearing seat 509 on the outer diameter to swing back and forth, so that the swing rods 510 on both sides swing along. When the swing rods 510 swing, they will drive the two pistons 506 to move up and down alternately in the corresponding cylinder body 502 through the action of the connecting rod 511. When the piston 506 in the cylinder body 502 moves down, the air pressure in the cylinder body 502 decreases, and the first rubber one-way valve 521 is opened. The cleaning liquid in the cleaning liquid storage box 501 will be sucked into the cylinder 502. When the piston 506 moves up, the air pressure in the cylinder 502 increases, the first rubber one-way valve 521 is closed and the second rubber one-way valve 522 is opened. The cleaning liquid enters the connecting pipe 503, and then is sprayed out through the outlet pipe 504 and the nozzle 505, spraying on the surface of the eggs to clean the surface before testing. The two pistons 506 move back and forth alternately, so that the cleaning liquid can be continuously sprayed on the surface of the eggs.

[0035] Furthermore, the upper sides of the inner ends of the cylinder 502 are fixedly connected to the two sides of the connecting pipe 503, and a water outlet pipe 504 is fixedly installed in the middle of the connecting pipe 503. The end of the water outlet pipe 504 extends to the outside of the cleaning liquid storage tank 501 and is fixedly installed with a nozzle 505. The first rubber one-way valve 521 is fixedly installed on the inner top of the cylinder 502, and the second rubber one-way valve 522 is fixedly installed on both sides of the inside of the connecting pipe 503.

[0036] Furthermore, a second transmission rod 513 is movably installed at the top of the base 1 near the rear side of the first transmission rod 507, a chuck 514 is fixedly installed at the top of the second transmission rod 513, and magnetic bars 515 are fixedly installed on both sides of the top of the chuck 514. When the main shaft 518 rotates, it will also drive the second worm 520 to rotate, and the rotating second worm 520 drives the second transmission rod 513 and the chuck 514 to rotate. The rotating chuck 514 will drive the magnetic bars 515 on both sides of the top to do circular motion. At this time, the aluminum bar 13 at the bottom of the egg tray 11 is located between the two magnetic bars 515. When the magnetic bar 515 rotates, it will drive the magnetic field to rotate, causing the magnetic flux of the aluminum bar 13 to change. At this time, the aluminum cylinder will be affected by the Ampere force and follow the direction of the magnetic field to rotate, thereby driving the egg tray 11 to rotate, driving the eggs to rotate, and cooperating with the spraying work of the nozzle 505 to achieve all-round cleaning of the eggs, improve the accuracy of subsequent detection, and facilitate subsequent packaging work.

[0037] Furthermore, a first worm gear 512 is fixedly mounted on the lower outer diameter of the first transmission rod 507, a second worm gear 516 is fixedly mounted on the lower outer diameter of the second transmission rod 513, a second motor 517 is fixedly mounted on the top rear side of the base 1 near the front side of the first transmission rod 507, a main shaft 518 is fixedly mounted on the driving end of the second motor 517, a first worm 519 is fixedly mounted on the outer diameter of one side of the main shaft 518 and the first worm 519 is meshingly connected to the inner end of the first worm gear 512, a second worm 520 is fixedly mounted on the outer diameter of the other side of the main shaft 518 and the second worm 520 is meshingly connected to the inner end of the second worm gear 516.

[0038] Furthermore, the detection mechanism 6 includes a lifting cylinder 601, which is fixedly installed on the top right side of the base 1. A Z-shaped bending frame 602 is fixedly installed on the driving end of the lifting cylinder 601, and a transparent glass bottle 603 is fixedly installed on the end of the Z-shaped bending frame 602. A detection camera 604 is fixedly installed on the top right side of the truncated table 3. After cleaning, the egg tray 11 continues to be controlled to move into the detection mechanism 6, and the lifting cylinder 601 is started. The lifting cylinder 601 lifts the transparent glass bottle 603 through the Z-shaped bending frame 602, so that the entire egg is immersed in the transparent glass bottle 603. The transparent glass bottle 603 is provided with a detection liquid. Fresh eggs have a small internal air chamber and small buoyancy, so they will sink to the bottom of the detection liquid. Stale eggs have a large internal air chamber and large buoyancy, so they will float on the surface of the detection liquid. The detection camera 604 is used to capture the floating state of the egg, so as to determine whether the egg is fresh. After the detection is completed, the lifting cylinder 601 controls the transparent glass bottle 603 to reset.

[0039] Furthermore, the loading mechanism 4 includes a feeding conveyor belt 401, which is mounted on the left side of the truncated table 3, a first fixed plate 402 is fixedly installed on the side of the feeding conveyor belt 401 away from the truncated table 3, an electric cylinder 403 is movably installed on the top of the first fixed plate 402, a second fixed plate 404 is fixedly installed on the side of the feeding conveyor belt 401 close to the truncated table 3, a swing frame 406 is movably installed on the second fixed plate 404 through a short shaft 405, and the top of the swing frame 406 is movably installed on the end of the electric cylinder 403, a limiting frame 407 is fixedly installed in the middle of the second fixed plate 404, baffles 408 are movably installed on both sides of the swing frame 406, and the ends of the baffles 408 respectively pass through the inner sides of the limiting frame 407 and extend to the top of the feeding conveyor belt 401, firstly, the staff puts the eggs to be tested one by one on the feeding conveyor belt 401, starts the feeding conveyor belt 401, and the feeding conveyor belt 401 transports the eggs to the second fixed plate 404 When the fixed plate 404 is on one side, it will be blocked by the baffle 408 on the left side. At this time, the electric cylinder 403 is started. When the electric cylinder 403 controls the internal telescopic rod to reciprocate and retract, it will drive the swing frame 406 to swing back and forth around the short axis 405. The reciprocating swing frame 406 will drive the baffles 408 on both sides to lift and lower alternately back and forth. When the baffle 408 on the left side rises, the baffle 408 on the right side drops. The first egg will enter between the two baffles 408 through the transportation of the feeding conveyor belt 401 and be blocked by the baffle 408 on the right side. When the baffle 408 on the right side rises, the baffle 408 on the left side drops, and the second egg will be blocked by the baffle 408 on the left side. At the same time, the baffle 408 on the right side releases the blocking effect on the first egg. Through the transportation effect of the feeding conveyor belt 401, the first egg will be sent to the egg tray 11 at the bottom of the bending bracket 9, and the cycle is repeated to achieve intermittent delivery of all eggs to all egg trays 11, which is convenient for subsequent detection work.

[0040] Furthermore, the discharging mechanism 7 includes a discharging conveyor belt 701, which is mounted on the front side of the truncated table 3, a partition plate 702 is fixedly installed in the middle of the discharging conveyor belt 701, a notch 703 is opened on the side of the discharging conveyor belt 701 close to the truncated table 3, a pushing cylinder 704 is fixedly installed on the front side of the top of the truncated table 3, and a pushing plate 705 is fixedly installed on the driving end of the pushing cylinder 704, and the egg tray is continuously controlled to move into the discharging mechanism 7, and the pushing cylinder 704 is started. The pushing cylinder 704 pushes the pushing plate 705 to move outward, and the eggs in the egg tray 11 are sent to the discharging conveyor. When the eggs are fresh, the pushing plate 705 moves outward a short distance, and the eggs are sent to the inner side of the partition plate 702. When the eggs are not fresh, the pushing plate 705 moves outward a long distance, and the eggs are sent to the outer side of the partition plate 702, which is convenient for sorting the eggs.

[0041] Working principle: First, the staff puts the eggs to be tested one by one onto the feed conveyor 401 and starts the feed conveyor 401. When the feed conveyor 401 transports the eggs to the side of the second fixed plate 404, it will be blocked by the baffle 408 on the left. At this time, the electric cylinder 403 is started. When the electric cylinder 403 controls the internal telescopic rod to reciprocate, it will drive the swing frame 406 to swing back and forth around the short axis 405. The reciprocating swinging swing frame 406 will drive the baffles 408 on both sides to alternately rise and fall. When the baffle 408 on the left rises, the baffle 408 on the right falls. The first egg is transported by the feed conveyor 401 and enters between the two baffles 408 and is blocked by the baffle 408 on the right. When the baffle 408 on the right rises, The left baffle plate 408 descends, and the second egg will be blocked by the left baffle plate 408. At the same time, the right baffle plate 408 releases the blocking effect on the first egg. Through the transportation effect of the feeding conveyor belt 401, the first egg will be sent to the egg tray 11 at the bottom of the bending bracket 9. The cycle is repeated to achieve intermittent delivery of all eggs to all egg trays 11, which is convenient for subsequent inspection work. When the egg enters the egg tray 11, the first motor 14 is started, and the driving bevel gear 15 is driven to rotate by the first motor 14, driving the driven bevel gear 16 and the rotating shaft 8 to rotate, thereby driving all the bending brackets 9 and the egg tray 11 to rotate and move, which is convenient for subsequent feeding work. At the same time, the egg is sent to the cleaning mechanism 5, and the second motor 5 is started at this time. 17, the main shaft 518 is driven to rotate by the second motor 517, which drives the first worm 519 to rotate. The rotating first worm 519 drives the first transmission rod 507 and the top cylinder 508 to rotate through meshing transmission. Since there is a certain angle between the ball groove on the outer diameter of the cylinder 508 and the central axis of the cylinder 508, when the cylinder 508 rotates, it will drive the two sides of the oblique bearing seat 509 on the outer diameter to swing back and forth, so that the swing rods 510 on both sides swing along. When the swing rod 510 swings, it will drive the two pistons 506 to reciprocate up and down in the corresponding cylinder 502 through the action of the connecting rod 511. When the piston 506 in the cylinder 502 moves down, the air pressure in the cylinder 502 decreases, and the first rubber one-way valve 521 is opened, clearing The cleaning liquid in the cleaning liquid storage box 501 will be sucked into the cylinder 502. When the piston 506 moves upward, the air pressure in the cylinder 502 increases, the first rubber one-way valve 521 is closed and the second rubber one-way valve 522 is opened, and the cleaning liquid enters the connecting pipe 503, and then is sprayed out through the outlet pipe 504 and the nozzle 505, sprayed on the surface of the eggs to clean the surface of the eggs before testing. The two pistons 506 alternately move back and forth to continuously spray the cleaning liquid on the surface of the eggs. At the same time, when the main shaft 518 rotates, it also drives the second worm 520 to rotate. The rotating second worm 520 drives the second transmission rod 513 and the chuck 514 to rotate. The rotating chuck 514 drives the magnetic bars 515 on both sides of the top to do circular motion.At this time, the aluminum rod 13 at the bottom of the egg tray 11 is located between the two magnetic rods 515. When the magnetic rod 515 rotates, it will drive the magnetic field to rotate, causing the magnetic flux of the aluminum rod 13 to change. At this time, the aluminum cylinder will be affected by the Ampere force and follow the direction of the magnetic field to rotate, thereby driving the egg tray 11 to rotate and the eggs to rotate. In conjunction with the spraying work of the nozzle 505, the eggs can be cleaned in all directions, the accuracy of subsequent inspections can be improved, and subsequent packaging work can be facilitated. After cleaning, the egg tray 11 is continued to be controlled to move into the inspection mechanism 6, and the lifting cylinder 601 is started. The lifting cylinder 601 lifts the transparent glass bottle 603 through the Z-shaped bending frame 602, so that the entire egg is immersed in the transparent glass bottle 603. The transparent glass bottle 603 is provided with an inspection mechanism. Liquid testing, fresh eggs will sink to the bottom of the testing liquid due to their small internal air chamber and small buoyancy, while stale eggs will float on the surface of the testing liquid due to their large internal air chamber and large buoyancy. The detection camera 604 is used to capture the floating state of the eggs, so as to determine whether the eggs are fresh. After the detection is completed, the lifting cylinder 601 controls the transparent glass bottle 603 to reset, and continues to control the egg tray to move into the discharging mechanism 7, and starts the pushing cylinder 704. The pushing cylinder 704 pushes the pushing plate 705 to move outward, and the eggs in the egg tray 11 are sent to the discharging conveyor. When the eggs are fresh, the pushing plate 705 moves outward a short distance, and the eggs are sent to the inner side of the partition 702. When the eggs are not fresh, the pushing plate 705 moves outward a long distance, and the eggs are sent to the outer side of the partition 702, which is convenient for sorting eggs.
