Egg tray washing mechanism

Abstract

The application discloses an egg tray cleaning mechanism and relates to the technical field of egg tray cleaning, which comprises a tension spring, a sleeve and a piston tube. A control valve intermittently controls high-pressure atomized liquid to enter the sleeve. The high-pressure atomized liquid is injected into the sleeve, and the sleeve gas pressure becomes larger to push the piston tube to move downward. When the control valve is closed, the tension spring pulls the piston tube to reset. A sealing sleeve, an air-tight pad and a nozzle are arranged. The sealing sleeve is installed on the outer side of the upper end of the piston tube. When the air-tight pad is sealed with the piston tube, the high-pressure atomized liquid pushes the piston tube to move downward. When the air-tight pad is ventilated with the piston tube, the high-pressure atomized liquid enters the piston tube and is discharged from the nozzle. The beneficial effect of the application is that the cleaning liquid is atomized by the high-pressure atomization host, then is injected into the sleeve in a high-pressure mode, and finally is sprayed from the nozzle. The control valve is intermittently opened and closed, so that the piston tube, the hemispherical brush and the nozzle move up and down at a high frequency to clean the surface and the groove position of the egg tray. Meanwhile, the high-pressure atomized liquid is discharged from the nozzle, thereby further improving the cleaning effect.

Description

Technical Field

[0001] This invention relates to the field of egg tray cleaning technology, and more specifically, to an egg tray cleaning mechanism. Background Technology

[0002] Egg trays are a common tool for transporting eggs, especially in food factories that process egg products, such as on a braised egg production line. Plastic egg trays are reusable and require frequent cleaning. In existing technologies, such as the document with application number CN202411831008.2, the egg trays are cleaned using a non-contact method with high-pressure cleaning fluid and a spray nozzle. Although this method can clean the trays, it cannot effectively remove stubborn stains.

[0003] For example, the application with application number CN201811509344.X cleans the egg tray using a cleaning brush, but it uses a roller brush. Due to the structural limitations of the roller brush, when the roller brush rotates, it can only sweep across the upper or lower surface of the egg tray to achieve cleaning; however, it cannot clean the grooves or corners of the egg tray, and the cleaning is not thorough enough. Summary of the Invention

[0004] To address the above deficiencies, this invention provides an egg tray cleaning mechanism, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The egg tray cleaning mechanism includes a support frame, a conveyor belt, egg trays, a hemispherical brush, a high-pressure atomizing unit, and a control valve. The high-pressure atomizing unit generates high-pressure atomized liquid. The side walls of the egg trays are equipped with baffles. The conveyor belt has a pair of baffles placed on it. The mechanism also includes:

[0007] The tension spring, sleeve, and piston tube are connected. The control valve intermittently controls the high-pressure atomizing liquid to enter the sleeve. When the high-pressure atomizing liquid is injected into the sleeve, the air pressure in the sleeve increases and pushes the piston tube downward. When the control valve is closed, the tension spring pulls the piston tube back to its original position.

[0008] The system includes a sealing sleeve, an airtight gasket, and a nozzle. The airtight gasket is installed on the inner side of the upper end of the piston tube, and the sealing sleeve is installed on the outer side of the upper end of the piston tube. When the airtight gasket seals with the piston tube, the high-pressure atomized liquid pushes the piston tube downward. When the airtight gasket and the piston tube are ventilated, the high-pressure atomized liquid enters the piston tube and is discharged from the nozzle. The nozzle is installed at the lower end of the piston tube.

[0009] A hemispherical brush is placed on the surface of the nozzle. The hemispherical brush and the nozzle move up and down at high frequency to clean the surface of the egg tray, while high-pressure atomized liquid is discharged from the nozzle.

[0010] Furthermore, a pair of crossbeams are installed on the support frame, located above and below the conveyor belt respectively. A housing is installed on the crossbeam, and a fixing plate is installed inside the housing. The sleeve passes through the fixing plate and is fixedly connected to the fixing plate. A control valve is installed on the upper end of the sleeve. A connecting pipe is installed on the housing. A diverter pipe is installed at one end of the connecting pipe and is connected to the control valve. The other end of the connecting pipe is connected to the high-pressure atomizing host. One end of the tension spring is connected to the piston tube, and the other end is connected to the housing.

[0011] Furthermore, the inner wall of the sleeve is provided with a limiting groove, and the sealing sleeve is sealed to the limiting groove. The sealing sleeve is hollow and has an air inlet at the upper end. The air inlet is constricted. The airtight pad is in a state of being in contact with or separated from the air inlet. The side wall of the airtight pad is an annular slope. The lower half of the annular slope is provided with a venting notch. A pin is provided below the airtight pad. A three-pronged bracket is installed on the inner wall of the sealing sleeve. A support ring is provided at the center of the three-pronged bracket. The pin is inserted into the support ring. A compression spring is installed between the support ring and the airtight pad. A slow-release component is installed on the airtight pad.

[0012] Furthermore, the sustained-release component includes strip-shaped protrusions disposed on the upper half of the annular inclined surface, the strip-shaped protrusions being arranged radially.

[0013] Furthermore, the slow-release component includes a limiting ring disposed on the side wall of the three-pronged bracket, a tapered rod installed on the lower surface of the airtight pad, and a swing bar hinged to the side wall of the tapered rod, with one side of the swing bar being smooth and the other side being rough.

[0014] Furthermore, a rotating assembly is installed between the nozzle and the piston tube. The rotating assembly includes an inner liner installed at the lower end of the piston tube, a rotating tube installed on the nozzle, the rotating tube penetrating the inner liner, a sealing ring installed at the upper end of the rotating tube, a spiral groove provided on the side wall of the inner liner, an interference block installed on the side wall of the rotating tube, the interference block being inserted into the spiral groove and moving along the spiral groove; a bearing is installed on the outer side of the lower end of the piston tube, and a compression spring is installed between the outer wall of the bearing and the nozzle.

[0015] Furthermore, the nozzle is equipped with a main air passage, which is connected to the piston tube. At the lower end of the main air passage, there are multiple U-shaped air passages, and multiple branch air passages are provided on the U-shaped air passages. The high-pressure atomized liquid is discharged sequentially through the main air passage, the U-shaped air passages, and the branch air passages.

[0016] Furthermore, a hydraulic rod is installed on the crossbeam below the conveyor belt, and a rotary motor is installed on the telescopic end of the hydraulic rod. A plate is installed on the rotating end of the rotary motor, and a protrusion is provided on the upper surface of the plate, which fits against the lower surface of the egg tray. A collection box is installed on the crossbeam above the conveyor belt, and a rectangular opening is opened at the lower end of the collection box. An inclined plate is installed on the rectangular opening, and an annular groove is formed between the inclined plate and the collection box. A limit tube is installed on the upper surface of the collection box, and a squeezing rod is installed inside the limit tube. A compression spring is installed between the squeezing rod and the collection box. A bearing is installed at the lower end of the squeezing rod, and a plate is installed on the outer ring of the bearing. A protrusion is installed on the lower surface of the plate, which fits against the upper surface of the egg tray.

[0017] Furthermore, a pipe is installed inside the box, and the piston tube passes through the pipe.

[0018] The beneficial effects of this invention are: the cleaning liquid is atomized by the high-pressure atomizing host, then injected into the sleeve under high pressure, and finally sprayed out from the nozzle. The control valve opens and closes intermittently, causing the piston tube, hemispherical brush and nozzle to move up and down at high frequency to clean the surface of the egg tray and the groove. At the same time, the high-pressure atomized liquid is discharged from the nozzle, further improving the cleaning effect.

[0019] The slow-release component allows the cavity pressure between the sleeve and the piston tube to be zero, which is beneficial for the complete discharge of the high-pressure atomizing liquid and for the rapid reset of the tension spring.

[0020] The egg tray can be rotated at high speed by the action of hydraulic rods and rotary motors, which shakes off the moisture remaining on the egg tray. Attached Figure Description

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] This application provides an egg tray cleaning service; please refer to [the relevant documentation]. Figures 1-11 The system includes a support frame 1, a conveyor belt 2, an egg tray 3, a hemispherical brush 4, a high-pressure atomizing host 5, and a control valve 6. The high-pressure atomizing host 5 generates high-pressure atomized liquid. The side wall of the egg tray 3 is provided with an orifice-shaped partition 7. The conveyor belt 2 is provided with a pair of orifice-shaped partitions 7, which are placed on the conveyor belt 2.

[0035] The tension spring 8, sleeve 9, and piston tube 10 are connected by the control valve 6, which intermittently controls the high-pressure atomizing liquid to enter the sleeve 9. When the high-pressure atomizing liquid is injected into the sleeve 9, the air pressure in the sleeve 9 increases, pushing the piston tube 10 downward. When the control valve 6 is closed, the tension spring 8 pulls the piston tube 10 back to its original position.

[0036] The sealing sleeve 11, the airtight gasket 12, and the nozzle 13 are provided. The airtight gasket 12 is installed on the inner side of the upper end of the piston tube 10, and the sealing sleeve 11 is installed on the outer side of the upper end of the piston tube 10. When the airtight gasket 12 is sealed with the piston tube 10, the high-pressure atomized liquid pushes the piston tube 10 downward. When the airtight gasket 12 is ventilated with the piston tube 10, the high-pressure atomized liquid enters the piston tube 10 and is discharged from the nozzle 13. The nozzle 13 is installed at the lower end of the piston tube 10.

[0037] A hemispherical brush 4 is placed on the surface of the nozzle 13. The hemispherical brush 4 and the nozzle 13 move up and down at high frequency to clean the surface of the egg tray 3, while high-pressure atomized liquid is discharged from the nozzle 13.

[0038] In practical applications, the conveyor belt 2 is a thin strip used to support the egg tray 3 and can be transported horizontally. The conveyor belt 2, hemispherical brush 4, high-pressure atomizing host 5, and control valve 6 are existing technologies and will not be described in detail. The shape of the hemispherical brush 4 fits the concave position of the egg tray 3. The high-pressure atomizing host 5 can atomize the cleaning liquid to form a high-pressure atomized liquid, which is delivered to the nozzle 13 in a high-pressure state. The control valve 6 can be opened and closed quickly. When closed, the piston tube 10 can be contracted quickly.

[0039] In actual operation, the high-pressure atomizing host 5 works to deliver the high-pressure atomized liquid to the position of the control valve 6;

[0040] Initial state; when control valve 6 is closed, the positive pressure in sleeve 9 is zero, and piston tube 10 is in a state of retraction within sleeve 9 under the action of tension spring 8.

[0041] Step 1: When the control valve 6 is opened, assuming that the high-pressure atomizing liquid generated by the high-pressure atomizing host 5 is 3 MPa, the airtight pad 12 can withstand 2 MPa air pressure, and the tension spring 8 can withstand 1 MPa air pressure.

[0042] The high-pressure atomizing liquid moves into the sleeve 9, and the pressure inside the sleeve 9 rises from 0 MPa to 3 MPa. At this time, the cavity between the sleeve 9 and the piston tube 10 slowly increases.

[0043] Step 2: When the air pressure in the cavity between the sleeve 9 and the piston tube 10 reaches 1.1 MPa, the airtight pad 12 does not open. First, the piston tube 10 is pushed to move towards the egg tray 3. At this time, the elastic force of the tension spring 8 is not enough to resist the piston tube 10, and the piston tube 10 moves downward quickly.

[0044] Piston tube 10 drives nozzle 13 and hemispherical brush 4 to press against egg tray 3. At this time, piston tube 10 is at the bottom dead center position, and the air pressure in the cavity between sleeve 9 and piston tube 10 quickly reaches 3 MPa.

[0045] Step 3: At this time, the airtight pad 12 opens quickly, and the high-pressure atomized liquid moves rapidly to the nozzle 13 and cleans the egg tray 3.

[0046] Step four: After that, control valve 6 is closed, and the pressure in the cavity between sleeve 9 and piston tube 10 gradually decreases;

[0047] When the pressure is less than 2 MPa, the airtight pad 12 closes; when the pressure is less than 1 MPa, the tension spring 8 pulls the piston tube 10 away from the egg tray 3.

[0048] Repeating the above steps, the piston tube 10 can impact the egg tray 3 at a high frequency, and the high-pressure atomized liquid is also sprayed out at a high frequency, achieving contact cleaning and making the cleaning more thorough.

[0049] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A crossbeam 21 is installed on the support 1. There are two crossbeams 21, which are located above and below the conveyor belt 2 respectively. A box 22 is installed on the crossbeam 21. A fixing plate 23 is installed inside the box 22. The sleeve 9 passes through the fixing plate 23 and is fixedly connected to the fixing plate 23. The control valve 6 is installed on the upper end of the sleeve 9. A connecting pipe 24 is installed on the box 22. A diverter pipe 25 is installed at one end of the connecting pipe 24. The diverter pipe 25 is connected to the control valve 6. The other end of the connecting pipe 24 is connected to the high-pressure atomizing host 5. One end of the tension spring 8 is connected to the piston tube 10, and the other end is connected to the box 22.

[0050] In practical applications, the crossbeam 21 is used to fix the box 22, the fixing plate 23 is fixedly connected to the box on all four sides, the sleeve 9 is fixedly connected to the fixing plate 23, and the high-pressure atomizing liquid enters the sleeve 9 through the connecting pipe 24, the diversion pipe 25, and the control valve 6 in sequence.

[0051] Reference Figures 1 to 6 The inner wall of the sleeve 9 is provided with a limiting groove 26. The sealing sleeve 11 is sealed to the limiting groove 26. The sealing sleeve 11 is hollow. The upper end of the sealing sleeve 11 has an air inlet 27. The air inlet 27 is constricted. The airtight pad 12 is in a state of being in contact or separated from the air inlet 27. The side wall of the airtight pad 12 is an annular inclined surface 28. The lower half of the annular inclined surface 28 is provided with a venting notch 29. A pin 291 is provided below the airtight pad 12. A three-pronged bracket 292 is installed on the inner wall of the sealing sleeve 11. A support ring 293 is provided at the center of the three-pronged bracket 292. The pin 291 is inserted into the support ring 293. A compression spring 294 is installed between the support ring 293 and the airtight pad 12. A slow-release component is installed on the airtight pad 12.

[0052] In practical applications, the limiting groove 26 is designed to give the sealing sleeve 11 an upper dead point and a lower dead point, and the air inlet 27 is a constricted shape.

[0053] When the pressure is zero, the elastic force of the compression spring 294 causes the airtight pad 12 to press tightly against the air inlet 27, and the airtight pad 12 is in a stationary state.

[0054] When the pressure can push open the airtight pad 12, the airtight pad 12 and the pin 291 move downward, and the high-pressure atomized liquid is quickly discharged into the piston tube 10 through the vent 29.

[0055] Through the action of the three-pronged bracket 292 and the support ring 293, air can be allowed to pass through while the pin 291 and the airtight pad 12 can slide up and down stably.

[0056] Example 1 of the sustained-release component, refer to Figure 1 , Figure 5 and Figure 6 The slow-release component includes strip-shaped protrusions 401 disposed on the upper half of the annular inclined surface 28, the strip-shaped protrusions 401 being arranged radially.

[0057] In practical applications, if a slow-release component is not provided, when the pressure in the cavity between the sleeve 9 and the piston tube 10 is less than the elastic force of the compression spring 294 (2 MPa in this application), the airtight pad 12 will close with the air inlet 27. At this time, a certain pressure of high-pressure atomized liquid will remain in the cavity between the sleeve 9 and the piston tube 10, and the discharge will be incomplete.

[0058] If the strip protrusion 401 is provided, when the pressure of the high-pressure atomizing liquid is greater than 2 MPa, the high-pressure atomizing liquid will be discharged quickly through the vent 29. When the pressure of the high-pressure atomizing liquid is less than 2 MPa, it will be discharged slowly through the gap between the strip protrusions 401. At this time, the cavity pressure between the sleeve 9 and the piston tube 10 can be equal to zero, which is conducive to the complete discharge of the high-pressure atomizing liquid and the rapid reset of the tension spring 8.

[0059] Example 2 of the sustained-release component, refer to Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 The slow-release component includes a limiting ring 411 disposed on the side wall of the three-pronged bracket 292, a tapered rod 412 mounted on the lower surface of the airtight pad 12, and a swing bar 413 hinged to the side wall of the tapered rod 412. One side of the swing bar 413 is smooth and the other side is rough.

[0060] In practical applications, the force required for the airtight pad 12 to open or close is 2 MPa. When the airtight pad 12 is opened, the smooth side of the swing bar 413 contacts the limiting ring 411, and the tapered rod 412 can be quickly inserted into the limiting ring 411.

[0061] When the airtight pad 12 is closed, the rough side of the swing bar 413 contacts the limiting ring 411. At this time, the reset speed of the conical rod 412 and the airtight pad 12 is slowed down, allowing the high-pressure atomized liquid to be discharged more thoroughly.

[0062] The desired result is that, with the same force, the airtight pad 12 can be opened quickly, but when closing, it needs to be delayed to allow the high-pressure atomized liquid to be discharged.

[0063] Reference Figure 2 , Figure 3 , Figure 4 and Figure 9 A rotating assembly is installed between the nozzle 13 and the piston tube 10. The rotating assembly includes an inner liner 61 installed at the lower end of the piston tube 10, a rotating tube 62 installed on the nozzle 13, the rotating tube 62 passing through the inner liner 61, a sealing ring 63 installed at the upper end of the rotating tube 62, a spiral groove 64 provided on the side wall of the inner liner 61, an interference block 65 installed on the side wall of the rotating tube 62, the interference block 65 being inserted into the spiral groove 64 and moving along the spiral groove 64; a bearing 66 is installed on the outer side of the lower end of the piston tube 10, and a compression spring 67 is installed between the outer wall of the bearing 66 and the nozzle 13.

[0064] In practical applications, in order to improve the cleaning effect, the hemispherical brush 4 can rotate after it is pressed against the egg tray 3. The specific process is as follows:

[0065] After the hemispherical brush 4 presses against the egg tray 3, the piston tube 10 continues to move downward, and the rotating tube 62 moves in the opposite direction to the piston tube 10. The spiral groove 64 on the inner liner 61 drives the interference block 65, the nozzle 13 and the hemispherical brush 4 to rotate. When the piston tube 10 moves upward as a whole, the setting of the compression spring 67 facilitates the rotation tube 62 and the piston tube 10 to move in opposite directions, thereby achieving a reset.

[0066] The bearing 66 causes the compression spring 67 to rotate with the nozzle 13, preventing the compression spring 67 from twisting circumferentially; the sealing ring 63 allows the high-pressure atomized liquid to be discharged through the rotating tube 62, preventing leakage.

[0067] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 10 The nozzle 13 is provided with a main air passage 71, which is connected to the piston tube 10. The lower end of the main air passage 71 is provided with multiple U-shaped air passages 72, and multiple branch air passages 73 are provided on the U-shaped air passages 72. The high-pressure atomized liquid is discharged through the main air passage 71, the U-shaped air passages 72 and the branch air passages 73 in sequence.

[0068] In practical applications, the nozzle 13 and the piston tube 10 are in a connected state, and the high-pressure atomized liquid is discharged through the main air passage 71, the U-shaped air passage 72 and finally through the branch air passage 73.

[0069] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 11 A hydraulic rod 81 is installed on the crossbeam 21 below the conveyor belt 2. A rotary motor 82 is installed on the telescopic end of the hydraulic rod 81. A plate 83 is installed on the rotating end of the rotary motor 82. A protrusion 84 is provided on the upper surface of the plate 83, and the protrusion 84 fits against the lower surface of the egg tray 3. A collection box 85 is installed on the crossbeam 21 above the conveyor belt 2. A rectangular opening 86 is opened at the lower end of the collection box 85. An inclined plate 87 is installed on the rectangular opening 86, and an annular groove 88 is formed between the inclined plate 87 and the collection box 85. A limit tube 89 is installed on the upper surface of the collection box 85. A compression rod 801 is installed inside the limit tube 89. A compression spring 802 is installed between the compression rod 801 and the collection box 85. A bearing 803 is installed at the lower end of the compression rod 801. A plate 804 is installed on the outer ring of the bearing 803. A protrusion 805 is installed on the lower surface of the plate 804, and the protrusion 805 fits against the upper surface of the egg tray 3.

[0070] In practical application, after cleaning, the conveyor belt 2 moves the egg tray 3 to the collection box 85. At this time, the hydraulic rod 81 extends, driving the egg tray 3 to move upward. The first protrusion 84 fits against the lower surface of the egg tray 3. When the egg tray 3 moves upward, it hits the second plate 804, and the compression spring 802 is compressed. At this time, the second plate 804 and the first plate 83 clamp the egg tray 3. The rotary motor 82 rotates, indirectly driving the egg tray 3 to rotate at high speed. Through the action of the first protrusion 84 and the second protrusion 805, the egg tray 3 rotates stably. The excess water on the egg tray 3 is spun off by centrifugal force.

[0071] Excess water is collected in the annular trough 88 and then discharged.

[0072] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A pipe 91 is installed inside the housing 22, and the piston pipe 10 passes through the pipe 91.

[0073] In practical applications, the setting of tube 91 enables the piston tube 10 to slide stably.
