Description

Technical Field

[0001] This application relates to the field of egg tray cleaning technology, and in particular to an egg tray cleaning line. Background Technology

[0002] Egg trays may become contaminated with various stains, bacteria, and microorganisms during use. If these contaminants are not thoroughly cleaned, they may contaminate egg products and pose a threat to consumers' health. Egg tray cleaning devices can effectively remove dirt, bacteria, and viruses from the surface of egg trays through high-pressure water jets, cleaning agents, and disinfectants, ensuring that egg trays meet food-grade hygiene standards.

[0003] In the prior art, the relevant technology for cleaning egg trays can be found in Chinese Patent No. CN216989070U, which discloses a double-sided cleaning device for egg trays. The device includes a cleaning chamber with egg tray conveying devices at both ends, which convey the egg trays from one end to the other. Several cleaning components are linearly arranged inside the cleaning chamber along the conveying direction. Each cleaning component includes an upper cleaning brush roller and a lower cleaning brush roller, which are rotatably arranged vertically within the cleaning chamber. The upper and lower cleaning brush rollers have channels for the egg trays to pass through. A spraying device is provided on one side of each of the upper and / or lower cleaning brush rollers. This invention can efficiently clean the top and bottom of the egg trays while ensuring a cleanliness level. During the development of this application, the inventors discovered the following problems with the prior art:

[0004] The existing egg tray cleaning lines do not have the function of separating and cleaning stacked egg trays individually. In addition, after cleaning, the egg trays often need to be manually stacked, so they do not have the effect of automatic stacking, and they often do not have the function of automatic transfer after stacking. Summary of the Invention

[0005] The purpose of this application is to provide an egg tray cleaning line.

[0006] Firstly, the egg tray cleaning line provided in this application adopts the following technical solution:

[0007] An egg tray cleaning line includes a fixed frame, an egg tray placement rack on one side of the fixed frame, and limit guide rods on both inner walls of the egg tray placement rack. A separation mechanism is provided on the bottom side of the two sets of limit guide rods. The separation mechanism includes a fixed cover, adjusting rollers, a transmission belt, limit protrusions, and a servo motor. The fixed cover is located below the inner walls of both sides of the egg tray placement rack. Adjusting rollers are arranged on the side of the fixed cover away from the inner wall of the egg tray placement rack. The two sets of adjusting rollers are connected to the fixed cover via bearings, and a transmission belt is sleeved on the outer wall of the two sets of adjusting rollers. Limit protrusions are arranged on the surface of the transmission belt. A servo motor is located on the outer wall of one side of the fixed cover. The output end of the servo motor is connected to the adjusting roller on the top side. The servo motor drives the adjusting roller on one side to rotate, thereby causing the transmission belt and the limit protrusions to rotate. The transmission belt drives the adjusting rollers on both sides to rotate synchronously. A transmission chain runs through the middle of the fixed frame, and one end of the transmission chain is located at the bottom of the egg tray placement rack.

[0008] By adopting the above technical solution, the fixed frame provides support. During egg tray cleaning, the egg trays can be placed in the egg tray rack, and the limiting guide rods limit and guide the egg trays. The separation mechanism can separate the stacked egg trays into individual egg trays for transport. The transmission chain acts as a transmission chain for the egg trays, driven by a transmission gear, motor, and reducer. The transmission chain is an existing mechanism and has not been explained in detail. When cleaning the egg trays, the corresponding transmission belts on both sides clamp the egg trays. The limiting protrusions increase the friction with the egg trays. The servo motor drives the adjustment roller on one side to rotate, which in turn drives the transmission belt and the limiting protrusion to rotate. The transmission belt also causes the adjustment rollers on both sides to rotate synchronously. The rotation of the transmission belt guides the stacked egg trays sequentially. Together with the transmission chain at the bottom, it transports a single set of egg trays. After transport, the transmission belt continues to rotate, thus separating the stacked egg trays into individual egg trays for subsequent individual cleaning and improving cleaning efficiency.

[0009] A disinfection water tank is provided on one side of the bottom of the fixed frame. A disinfection hot water inlet is provided at one end of the top of the disinfection water tank, and a disinfection water tank drain outlet is provided on one side of the bottom of the disinfection water tank. A spray hood is provided on the top of the disinfection water tank. The spray hood is fitted in the middle of the fixed frame. An upper spray pipe is provided on the inner wall of the top of the spray hood, and a lower spray pipe is provided on the inner wall of the bottom of the spray hood. The transmission chain is located in the middle of the lower spray pipe and the upper spray pipe.

[0010] By adopting the above technical solution, the disinfectant water in the disinfection tank can be replenished through the disinfection hot water inlet. The egg trays inside the spray hood can be thoroughly cleaned by the cooperation of the upper and lower spray pipes. The spray hood plays a protective role in preventing the sprayed disinfectant water from spraying out of the device.

[0011] A conduit is connected to one side of the outer wall of the disinfection tank. The end of the conduit away from the disinfection tank passes through the spray hood and is connected to the lower and upper spray pipes via a diverter. A water pump is installed in the middle of the conduit. Disinfection nozzles are arranged and connected on the opposite side of the lower and upper spray pipes. A return pipe is connected to the bottom side of the spray hood. The end of the return pipe away from the spray hood is connected to the disinfection tank. A circulating water pump is installed in the middle of the return pipe. A replenishment tank is connected to the top of the disinfection tank. A solenoid valve is installed at the connection between the replenishment tank and the disinfection tank.

[0012] By adopting the above technical solution, when disinfecting and rinsing the egg trays, water is pumped from the disinfection tank and transmitted through conduits to the upper and lower spray pipes. High-pressure disinfection and rinsing is then performed on both sides of the egg trays via disinfection nozzles, achieving comprehensive cleaning. After spraying, the disinfectant water is collected in the spray hood and returned to the disinfection tank via a circulating water pump and return pipe, facilitating continuous spraying of the egg trays and saving water resources. The replenishment tank stores disinfectant and has a replenishment port at the top. When the disinfectant efficiency decreases after a period of disinfection, a solenoid valve is opened to replenish the disinfectant, maintaining continuous and efficient disinfection through water circulation. The solenoid valve can be controlled by the electrical control box to open and close at set times, achieving automatic replenishment. A filter screen is installed at the connection between the return pipe and the spray hood to filter impurities and prevent them from flowing back into the disinfection tank.

[0013] A clean water rinsing hood is provided on one side of the spray hood, and both sides of the clean water rinsing hood are connected to tap water spray pipes. The ends of the tap water spray pipes are connected to clean water nozzles. A water receiving tray is provided at the bottom of the spray hood. A tap water collection tank is provided on one side of the disinfection water tank. The tap water collection tank and the water receiving tray are connected by a water pipe. A sewage drain outlet is provided on one side of the tap water collection tank.

[0014] By adopting the above technical solution, the water rinsing cover plays a role in limiting and supporting protection. The tap water spray pipe can be connected to tap water for rinsing. The water nozzles at the ends of the tap water spray pipes on both sides can rinse the egg trays with clean water, thereby washing away the disinfectant on the surface of the egg trays and improving the cleanliness of the egg trays. The water can be collected by the water receiving tray and then transferred to the tap water collection tank. The sewage in the tap water collection tank can be discharged through the sewage drain outlet for subsequent water treatment. By disinfecting and rinsing the egg trays with clean water after spraying, the cleanliness of the egg trays is improved.

[0015] A dewatering brush is provided on the side of the water rinsing hood away from the spray hood. A drying fan is arranged on one side of the dewatering brush. An electrical control box is provided above one side of the fixed frame. A slide is provided on the side of the fixed frame away from the egg tray rack. An auxiliary cylinder is provided on the bottom side of the slide. A push plate is connected to the output end of the auxiliary cylinder.

[0016] By adopting the above technical solution, the dewatering brush can be driven to rotate by a motor. When the egg tray is conveyed to the dewatering brush by the transmission chain, it can be initially dried by the dewatering brush. Then, multiple sets of drying fans are used to dry the egg tray quickly. After drying, it can be conveyed to the slide by the transmission chain. After the egg tray reaches the slide, it automatically slides onto the surface of the conveyor belt by gravity. At the same time, the push plate pushed by the auxiliary cylinder can provide an auxiliary pushing effect so that the egg tray can be smoothly transferred to the surface of the conveyor belt.

[0017] A conveyor belt is provided on one side of the bottom of the push plate, and an egg tray collection rack is provided on the top of one side of the conveyor belt. Electric telescopic rods are bolted to the middle of the frame on both sides of the egg tray collection rack. A moving block is provided at the bottom of the electric telescopic rod, and a guide rod is connected to the top of the moving block. A connecting ring is connected to the bottom of the electric telescopic rod, and the connecting ring is sleeved on the outer wall of the guide rod.

[0018] By adopting the above technical solution, the conveyor belt, with its existing structure, is driven by a motor to perform the conveying function. After the egg trays fall onto the surface of the conveyor belt, they are transported to the bottom of the egg tray collection rack by the conveyor belt. At the same time, the abutment rod blocks the egg trays to facilitate their stacking. The electric telescopic rod can drive the connecting ring to move up and down. The movement of the connecting ring drives the guide rod, which in turn drives the moving block to move up and down. Meanwhile, the guide rod can slide inside the connecting ring, so that the moving block can reciprocate laterally while moving up and down.

[0019] Both sides of the outer wall of the egg tray collection rack are bolted with abutting inclined blocks. Limiting grooves are provided on the inclined surfaces of the two sets of abutting inclined blocks. A slider is connected to the side surface of the two sets of moving blocks near the abutting inclined blocks on the outer wall. The slider is embedded in the limiting groove. The moving blocks are movably connected to the abutting inclined blocks.

[0020] By adopting the above technical solution, the inclined block acts as a limiting and fixing block. The limiting groove is inclined, and the slider can slide in the limiting groove during the lifting and lowering of the moving block to achieve the limiting effect. Since the limiting groove is inclined, when the moving block rises, the two sets of moving blocks move in the same direction, thereby driving the clamping plate and the buffer plate to move horizontally. This allows the two sets of buffer plates to clamp and lift the egg tray. After rising, the buffer plate lifts the egg tray, so that the new egg tray can move to the bottom center of the egg tray collection rack. Then, the electric telescopic rod drives the moving block to descend. During the descent, the two sets of moving blocks descend and move in opposite directions, thereby driving the clamping plate and the buffer plate to move horizontally outward. This cancels the clamping effect on the top egg tray, allowing the top egg tray to fall naturally above the bottom egg tray, thus realizing the stacking of egg trays. Then, the stacked egg trays are clamped and lifted again, and the automatic stacking of egg trays is realized.

[0021] Both sets of moving blocks are connected to clamping plates on the side away from the slider. Springs are arranged on the surface of the clamping plates, and a buffer plate is provided on the side of the springs away from the clamping plates.

[0022] By adopting the above technical solution, the clamping plate and the buffer plate can clamp and stack the egg trays. At the same time, the spring can prevent the buffer plate from clamping the egg trays too tightly, thereby damaging the egg trays.

[0023] The egg tray collection rack is provided with a limit strip on the side away from the fixed frame. An infrared sensor is provided at the bottom center of the limit strip. Electric push rods are connected to both sides of the bottom of the limit strip. The output ends of the two sets of electric push rods face opposite directions. The output ends of the electric push rods are connected to abutment rods. The electric push rods and the infrared sensor are connected to the electrical control box through wires.

[0024] By adopting the above technical solution, the limiting strip acts as a limit, the abutment rod acts as a blocking limit, and the infrared sensor is model TCRT5000. The infrared emitting tube of the infrared sensor continuously emits infrared light. When the egg tray stack appears in the detection range, the infrared light is reflected, causing the phototransistor to saturate, thus determining that the egg tray has reached the set height. When the egg tray stack reaches one side of the limiting strip, the infrared sensor detects that the egg tray stack has reached the specified height and transmits the signal to the controller inside the electrical control box. The controller inside the electrical control box controls the electric push rod to push to both sides, thereby pushing the abutment rod to move to both sides. This allows the cleaned egg tray stack to be transported to the next process position by the conveyor belt at the bottom, facilitating the transfer of the cleaned egg trays.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When cleaning egg trays, a servo motor drives one side of the adjusting roller to rotate, which in turn drives the transmission belt and the limiting protrusion to rotate. The transmission belt also causes the two side adjusting rollers to rotate synchronously. The rotation of the transmission belt guides the stacked egg trays in sequence. Together with the transmission chain at the bottom, it transports a single set of egg trays. After transport, the transmission belt continues to rotate, thus separating the stacked egg trays into individual egg trays for subsequent individual cleaning and improving cleaning efficiency.

[0027] 2. During stacking, the connecting ring can be raised and lowered by an electric telescopic rod. During the raising and lowering of the moving block, the slider slides in the limiting groove to achieve a limiting effect. Since the limiting groove is inclined, when the moving block rises, the two sets of moving blocks move in the same direction, thereby driving the clamping plate and the buffer plate to move horizontally. This allows the two sets of buffer plates to clamp and lift the egg tray. After rising, the buffer plate lifts the egg tray, allowing the new egg tray to move to the bottom center of the egg tray collection rack. Then, the electric telescopic rod drives the moving block to descend. During the descent, the two sets of moving blocks descend and move in opposite directions, thereby driving the clamping plate and the buffer plate to move horizontally outward. This cancels the clamping effect on the top egg tray, allowing the top egg tray to fall naturally above the bottom egg tray, thus realizing the stacking of egg trays. Then, the stacked egg trays are clamped and raised again, repeating the process to achieve automatic stacking of egg trays.

[0028] 3. The infrared sensor continuously emits infrared rays. When the egg tray stack appears within the detection range, the infrared rays are reflected, causing the phototransistor to saturate, thus determining that the egg tray has reached the set height. When the egg tray stack reaches the limit bar, the infrared sensor detects that the egg tray stack has reached the specified height and transmits the signal to the controller inside the electrical control box. The controller in the electrical control box controls the electric push rod to push to both sides, thereby pushing the abutment rod to move to both sides. This allows the cleaned egg tray stack to be transported to the next process position via the conveyor belt at the bottom, facilitating the transfer of the cleaned egg trays.

[0039] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This application will be described in further detail below.

[0040] Example: An egg tray cleaning line includes a fixed frame 1, an egg tray placement rack 2 is provided on one side of the fixed frame 1, and limit guide rods 3 are provided on both inner walls of the egg tray placement rack 2. A separation mechanism 4 is provided on the bottom side of the two sets of limit guide rods 3. The separation mechanism 4 includes a fixed cover 5, adjusting rollers 6, a transmission belt 7, a limit protrusion 8, and a servo motor 9. The fixed cover 5 is located below the inner walls of both sides of the egg tray placement rack 2. Adjusting rollers 6 are arranged on the side of the fixed cover 5 away from the inner wall of the egg tray placement rack 2. The two sets of adjusting rollers 6 are connected to the fixed cover 5 by bearings, and the outer walls of the two sets of adjusting rollers 6 are fitted with transmission belts 7. The surface of belt 7 is provided with limiting protrusions 8. A servo motor 9 is provided on one outer wall of the fixed cover 5. The output end of the servo motor 9 is connected to the top side adjusting roller 6. The servo motor 9 drives the side adjusting roller 6 to rotate, thereby driving the transmission belt 7 and the limiting protrusions 8 to rotate. The transmission belt 7 drives the two side adjusting rollers 6 to rotate synchronously. A transmission chain 10 is provided through the middle of the fixed frame 1, and one end of the transmission chain 10 is provided at the bottom of the egg tray placement rack 2. The fixed frame 1 provides support. When cleaning the egg trays, the egg trays can be placed in the egg tray placement rack 2, and the egg trays are limited and guided by the limiting guide rod 3. The stacked egg trays can be separated into individual trays for transport via the separation mechanism 4. The transmission chain 10 serves to transport the egg trays, driven by a transmission gear, motor, and reducer. The transmission chain 10 is an existing mechanism and therefore not explained in detail. When cleaning the egg trays, the two transmission belts 7 correspond to each other, thus clamping the ends of the stacked egg trays in the egg tray rack 2. The limiting protrusions 8 increase the friction with the egg trays. The servo motor 9 drives one side of the adjusting roller 6 to rotate, thereby causing the transmission belt 7 and the limiting protrusion 8 to rotate. The transmission belt 7 also causes the two side adjusting rollers 6 to... The synchronous rotation of the drive belt 7 guides the stacked egg trays sequentially. This, combined with the bottom drive chain 10, transports individual egg trays. After transport, the drive belt 7 continues to rotate. During the rotation of both drive belts 7, the egg trays are continuously transported downwards. When an egg tray reaches the bottom of the drive belt 7, it automatically falls onto the surface of the drive chain 10 for further transport. After leaving the bottom of the egg tray rack 2, the drive belt 7 continues to rotate, repeatedly lowering the egg trays. This process separates the stacked egg trays into individual trays for easier subsequent cleaning, improving cleaning efficiency.

[0041] A disinfection water tank 11 is installed on one side of the bottom of the fixed frame 1. A disinfection hot water inlet 111 is installed at the top of the disinfection water tank 11, and a disinfection water tank drain outlet 112 is installed on the bottom of the disinfection water tank 11. A spray hood 14 is installed on the top of the disinfection water tank 11 and is fitted in the middle of the fixed frame 1. An upper spray pipe 15 is installed on the inner wall of the top of the spray hood 14, and a lower spray pipe 16 is installed on the inner wall of the bottom of the spray hood 14. A drive chain 10 is installed in the middle of the lower spray pipe 16 and the upper spray pipe 15. The disinfection water in the disinfection water tank 11 can be replenished through the disinfection hot water inlet 111. The upper spray pipe 15 and the lower spray pipe 16 work together to clean the egg trays inside the spray hood 14. The spray hood 14 plays a protective role to prevent the sprayed disinfection water from spraying out of the device.

[0042] A conduit 12 is connected to one side of the outer wall of the disinfection tank 11. The end of the conduit 12 away from the disinfection tank 11 passes through the spray hood 14 and is connected to the lower spray pipe 16 and the upper spray pipe 15 via a diverter. A water pump 13 is installed in the middle of the conduit 12. Disinfection nozzles 17 are arranged and connected to the opposite sides of the lower spray pipe 16 and the upper spray pipe 15. A return pipe 18 is connected to the bottom side of the spray hood 14. The end of the return pipe 18 away from the spray hood 14 is connected to the disinfection tank 11. A circulating water pump 181 is installed in the middle of the return pipe 18. A replenishment tank 182 is connected to the top of the disinfection tank 11. A solenoid valve 183 is installed at the connection between the replenishment tank 182 and the disinfection tank 11. When disinfecting and rinsing the egg trays, the water in the disinfection tank 11 can be pumped by the water pump 13 and transmitted through the conduit 12 to the upper spray pipe 15 and the lower spray pipe 16 respectively. The egg tray is thoroughly cleaned by high-pressure disinfection and rinsing of both sides through the disinfection nozzle 17. After spraying, the disinfectant water is collected in the spray hood 14 and returned to the disinfection tank 11 via the circulating water pump 181 and the return pipe 18. This facilitates the continuous spraying of the egg tray and saves water resources. The replenishment tank 182 can store disinfectant and has a replenishment port on the top. When the efficiency of the disinfectant decreases after a period of disinfection, the disinfectant is replenished by opening the solenoid valve 183, thus maintaining the continuous and efficient disinfection of the disinfectant water. The solenoid valve 183 can be controlled by the electrical control box 27 to open and close at set times, thereby realizing the automatic replenishment function. At the same time, a filter screen is installed at the connection between the return pipe 18 and the spray hood 14 to filter impurities and prevent impurities from flowing back into the disinfection tank 11.

[0043] A clean water rinsing hood 19 is provided on one side of the spray hood 14. Both sides of the clean water rinsing hood 19 are connected to tap water spray pipes 20. The ends of the tap water spray pipes 20 are connected to clean water nozzles 21. A water receiving tray 22 is provided at the bottom of the spray hood 14. A tap water collection tank 23 is provided on one side of the disinfection water tank 11. The tap water collection tank 23 and the water receiving tray 22 are connected by a water pipe. A sewage drain outlet 24 is provided on one side of the tap water collection tank 23. The clean water rinsing hood 19 serves as a limit and support for protection. The spray pipe 20 can be connected to tap water for rinsing. The water nozzles 21 at the ends of the tap water spray pipes 20 on both sides can rinse the egg tray with clean water, thereby washing away the disinfectant on the surface of the egg tray and improving the cleanliness of the egg tray. The water collected by the water receiving tray 22 can be transferred to the tap water collection tank 23. The wastewater in the tap water collection tank 23 can be discharged through the wastewater drain outlet 24 for subsequent water treatment. The cleanliness of the egg tray is improved by disinfecting and rinsing it with clean water.

[0044] A water-removing brush 25 is provided on the side of the water rinsing hood 19 away from the spray hood 14. A drying fan 26 is arranged on one side of the water-removing brush 25. An electrical control box 27 is provided on the upper side of one side of the fixed frame 1. A slide 28 is provided on the side of the fixed frame 1 away from the egg tray placement rack 2. An auxiliary cylinder 29 is provided on the bottom side of the slide 28. A push plate 291 is connected to the output end of the auxiliary cylinder 29. The water-removing brush 25 can be driven to rotate by a motor. When the egg tray is conveyed to the water-removing brush 25 by the transmission chain 10, it can be initially dried by the water-removing brush 25. Then, multiple sets of drying fans 26 are used to dry the egg tray quickly. After drying, it can be conveyed to the slide 28 by the transmission chain 10. After the egg tray reaches the slide 28, it automatically slides down to the surface of the conveyor belt 30 by gravity. At the same time, the push plate 291 pushed by the auxiliary cylinder 29 can assist in pushing the egg tray so that it can be smoothly transferred to the surface of the conveyor belt 30.

[0045] A conveyor belt 30 is provided on one side of the bottom of the push plate 291. An egg tray collection rack 31 is provided on the top side of one side of the conveyor belt 30. Electric telescopic rods 32 are bolted to the middle of the frame on both sides of the egg tray collection rack 31. A moving block 33 is provided at the bottom of the electric telescopic rod 32. A guide rod 34 is connected to the top of the moving block 33. A connecting ring 35 is connected to the bottom of the electric telescopic rod 32. The connecting ring 35 is sleeved on the outer wall of the guide rod 34. The conveyor belt 30 is an existing structure that is driven by a motor to perform the conveying function. After the egg tray falls onto the surface of the conveyor belt 30, it is transferred to the bottom of the egg tray collection rack 31 by the conveyor belt 30. At the same time, the egg tray is blocked by the abutment rod 45 to facilitate the stacking work. The electric telescopic rod 32 can drive the connecting ring 35 to move up and down. The moving ring 35 moves up and down, which drives the guide rod 34, thereby driving the moving block 33 to move up and down. At the same time, the guide rod 34 can slide inside the connecting ring 35, so that the moving block 33 can slide back and forth laterally while moving up and down.

[0046] Both sides of the egg tray collection rack 31 are bolted with inclined blocks 36. Limiting grooves 37 are provided on the inclined surfaces of the two sets of inclined blocks 36. Slider blocks 38 are connected to the surfaces of the two sets of movable blocks 33 near the inclined blocks 36 on the outer wall. The sliders 38 are embedded in the limiting grooves 37. The movable blocks 33 are movably connected to the inclined blocks 36, which serve as limiting and fixing mechanisms. The limiting grooves 37 are inclined, allowing the sliders 38 to slide within the limiting grooves 37 during the lifting and lowering of the movable blocks 33, thus providing a limiting function. Because the limiting grooves 37 are inclined, the two sets of movable blocks 33 move in similar directions when the movable blocks 33 rise, thereby driving the clamping plate 3. The clamping plate 39 and the buffer plate 41 are moved horizontally, so that the two sets of buffer plates 41 clamp and lift the egg tray. After rising, the egg tray is lifted by the buffer plate 41, so that the new egg tray can move to the bottom center of the egg tray collection rack 31. Then, the electric telescopic rod 32 drives the moving block 33 to descend. During the descent, the two sets of moving blocks 33 descend and move in opposite directions, thereby driving the clamping plate 39 and the buffer plate 41 to move horizontally outward, thereby canceling the clamping effect on the top egg tray and allowing the top egg tray to fall naturally above the bottom egg tray, thus realizing the stacking of egg trays. Then, the stacked egg trays are clamped and lifted again, and the automatic stacking of egg trays is realized.

[0047] Both sets of moving blocks 33 are connected to clamping plates 39 on the side away from slider 38. Springs 40 are arranged on the surface of clamping plates 39. A buffer plate 41 is provided on the side of springs 40 away from clamping plates 39. The clamping plates 39 and buffer plates 41 can clamp and stack egg trays. At the same time, the springs 40 can prevent the buffer plates 41 from clamping the egg trays too tightly, thereby damaging the egg trays.

[0048] A limit strip 42 is provided on the side of the egg tray collection rack 31 away from the fixed frame 1. An infrared sensor 43 is located at the center of the bottom of the limit strip 42. Electric push rods 44 are connected to both sides of the bottom of the limit strip 42. The output ends of the two sets of electric push rods 44 face opposite directions. The output ends of the electric push rods 44 are connected to abutment rods 45. The electric push rods 44 and the infrared sensor 43 are connected to the electrical control box 27 by wires. The limit strip 42 serves as a limit, and the abutment rods 45 serve as a blocking limit. The infrared sensor 43 is a TCRT5000 model, which continuously emits infrared rays through its infrared emitting tube. When the egg tray stack appears within the detection range, the infrared light is reflected, causing the phototransistor to saturate, thus enabling the determination that the egg tray has reached the set height. When the egg tray stack reaches the limit bar 42, the infrared sensor 43 detects that the egg tray stack has reached the specified height and transmits the signal to the controller inside the electrical control box 27. The controller inside the electrical control box 27 controls the electric push rod 44 to push to both sides, thereby pushing the abutment rod 45 to move to both sides, so that the cleaned egg tray stack can be transferred to the next process position via the bottom conveyor belt 30, which facilitates the transfer of the cleaned egg tray.

[0049] The implementation principle of this application embodiment is as follows: First, when cleaning the egg trays, the egg trays can be placed in the egg tray rack 2. The egg trays are limited and guided by the limiting guide rod 3. The separation mechanism 4 can separate the stacked egg trays into individual egg trays for transport. The transmission chain 10 plays the role of transporting the egg trays. It is driven by the transmission gear plate, motor and reducer, etc. The transmission chain 10 is an existing mechanism and is not explained in detail. When cleaning the egg trays, the two transmission belts 7 on both sides correspond to each other to play a certain clamping role on the egg trays. The limiting protrusion can increase the friction with the egg trays. The servo motor 9 drives the adjustment roller 6 on one side to rotate, thereby driving the transmission belt 7 and the limiting protrusion 8 to rotate. The transmission belt 7 makes the adjustment rollers 6 on both sides rotate synchronously. The rotation of the transmission belt 7 plays the role of guiding the stacked egg trays in sequence. With the help of the transmission chain 10 at the bottom, a single set of egg trays is transported. After being transported, the transmission belt 7 continues to rotate, thereby realizing To separate stacked egg trays into individual trays for subsequent individual cleaning and improve cleaning efficiency, water is pumped from the disinfection tank 11 by water pump 13 and transmitted through conduit 12 to the upper spray pipe 15 and the lower spray pipe 16. The disinfection nozzles 17 then spray the upper and lower sides of the egg trays under high pressure, achieving comprehensive cleaning. After spraying, the disinfectant water is collected in the spray hood 14 and returned to the disinfection tank 11 by circulating water pump 181 and return pipe 18, allowing for cyclic spraying of the egg trays and saving water resources. At the same time, a filter screen is installed at the connection between the return pipe 18 and the spray hood 14 to filter impurities and prevent them from flowing back into the disinfection tank 11. The clean water nozzles 21 at the ends of the tap water spray pipes 20 on both sides can rinse the egg trays with clean water, thereby washing away the disinfectant on the surface of the egg trays and improving their cleanliness.

[0050] The sprayed water is collected by the water receiving tray 22 and then transferred to the tap water collection tank 23. Wastewater is discharged from the tap water collection tank 23 through the wastewater drain outlet 24 for subsequent water treatment. The egg trays are disinfected by spraying and then rinsed with clean water, thus improving their cleanliness. The dewatering brush 25, driven by a motor, allows the egg trays to be initially dried as they pass through the transmission chain 10. Multiple drying fans 26 then rapidly dry the egg trays. After drying, the trays are conveyed to the slide 28 via the transmission chain 10. After passing through point 28, the egg tray automatically slides down to the surface of the conveyor belt 30 by gravity. Simultaneously, the auxiliary cylinder 29 pushes the push plate 291 to assist in the transfer of the egg tray to the surface of the conveyor belt 30. During stacking, the electric telescopic rod 32 drives the connecting ring 35 to move up and down. During the lifting and lowering of the moving block 33, the slider 38 slides within the limiting groove 37 to provide a limiting function. Because the limiting groove 37 is inclined, when the moving block 33 rises, the two sets of moving blocks 33 move in similar directions, thereby causing the clamping plate 39 and the buffer plate 41 to move horizontally, thus allowing the two sets of buffer plates 41 to support the egg tray. The clamping mechanism lifts the egg trays, and after lifting, the buffer plate 41 supports the egg trays, allowing the new egg trays to move to the center of the bottom of the egg tray collection rack 31. Then, the electric telescopic rod 32 drives the moving blocks 33 to descend. During descent, the two sets of moving blocks 33 descend and move in opposite directions, causing the clamping plate 39 and the buffer plate 41 to move outwards, thus releasing the clamping effect on the top egg tray and allowing it to fall naturally onto the bottom egg tray, achieving egg tray stacking. The stacked egg trays are then clamped and lifted again in a repetitive motion, achieving automatic egg tray stacking. This is achieved through infrared sensors 43 emitting infrared light... The injection tube continuously emits infrared rays. When the egg tray stack appears within the detection range, the infrared rays are reflected, causing the phototransistor to saturate, thus determining that the egg tray has reached the set height. When the egg tray stack reaches the limit bar 42, the infrared sensor 43 detects that the egg tray stack has reached the specified height and transmits the signal to the controller inside the electrical control box 27. The controller inside the electrical control box 27 controls the electric push rod 44 to push to both sides, thereby pushing the abutment rod 45 to move to both sides. This allows the cleaned egg tray stack to be transported to the next process position via the bottom conveyor belt 30, facilitating the transfer of the cleaned egg tray.
