Description

Technical Field

[0001] This invention relates to the field of preserved egg production technology, specifically to a preserved egg production cleaning equipment and cleaning method. Background Technology

[0002] The main function of preserved egg cleaning equipment is to remove the lime and ash from the outer shell of preserved eggs to ensure their hygiene and appearance. During the production process, after the yeast fermentation period, a layer of lime and ash adheres to the eggshell surface. These substances not only affect the appearance of the preserved eggs but may also contain bacteria and impurities. This type of preserved egg cleaning equipment mainly consists of a cleaning tank, a cleaning water circulation system, cleaning nozzles, and a cleaning control system. The cleaning tank is the main component, used to hold and clean the preserved eggs. The cleaning water circulation system includes a water pump, water tank, and pipes, responsible for providing cleaning water and maintaining its cleanliness. The cleaning nozzles are installed at the top of the cleaning tank, spraying the cleaning water evenly onto the surface of the preserved eggs. The cleaning control system includes a control panel, sensors, and actuators for operating the equipment and monitoring the cleaning process. The structural principle is to utilize a cleaning water circulation system and cleaning nozzles to remove lime and grass ash from the surface of the preserved eggs using high-pressure water flow. For example, a cleaning device for preserved egg production disclosed in authorization announcement number CN117426329A includes a base plate and water tanks. A support pipe is installed at the upper end of the base plate, and a preserved egg conveyor belt is fixedly installed at one end of the support pipe. The surface of the preserved egg conveyor belt has several elliptical holes. There are two water tanks, and pipes are fixedly installed at the upper end of each water tank. A drive motor is installed at the upper end of each water tank, and a rotating shaft is fixedly connected to the output end of the drive motor. A first bevel gear is fixedly connected to the surface of the rotating shaft. The second bevel gear is engaged, and an elliptical hole is provided at the upper end of the preserved egg conveyor belt to facilitate the fixing of the preserved eggs on the conveyor belt for easy cleaning. By setting cleaning equipment and nozzles on the lower surface of the pipe, the preserved eggs enter the preserved egg conveyor belt and are washed by the corresponding cleaning equipment. However, in the implementation of the above technical solution, the preserved eggs to be cleaned are located in the elliptical hole of the conveyor belt. Since the nozzles spray cleaning liquid from top to bottom, the preserved egg part located inside the conveyor belt will be difficult to be sprayed and rinsed, thus forming a part of the cleaning blind spot. The uneven cleaning effect will result in some areas of the preserved egg surface still having lime soil and grass ash remaining, affecting the hygiene and appearance quality of the preserved eggs. At this time, rewashing is necessary. Summary of the Invention

[0003] The purpose of this invention is to provide a cleaning device and method for producing preserved eggs. Several preserved eggs to be cleaned are placed in a lower egg tray assembly, and an upper lifting egg tray applies pressure to the lower egg tray assembly to ensure the preserved eggs are positioned correctly. A rinsing device is arranged above the device. When the rinsing device sprays cleaning liquid downwards, a lifting unit brings the inverted U-shaped hollow frame and the roller-sweeping multi-point self-rotating cleaning module closer to the preserved eggs, causing the roller-sweeping multi-point self-rotating cleaning module to contact the lower surface of the preserved eggs. At this time, the upper part of the preserved eggs is rinsed, while the lower part is scrubbed. After the preserved eggs have been cleaned for a period of time, a flipping module rotates the upper lifting egg tray and the lower egg tray assembly 180 degrees, and the cleaning continues, thus solving the problems mentioned in the background art.

[0009] Preferably, the face-changing and flipping module includes a gear reduction drive unit installed on the inner wall of one side of the transmission box and a turntable rotatably installed on the outer wall of one side of the transmission box. The gear reduction drive unit is used to drive the turntable to rotate. One of the square-mouthed longitudinal arms is fixed on the outer wall of one side of the turntable. A right-angle seat is welded to the top of the square-mouthed longitudinal arm. An inverted right-angle seat is fixed on the outer wall of one side of the turntable. The right-angle seat and the inverted right-angle seat are bolted to each other.

[0010] Preferably, the lifting unit includes a mountain-shaped guide frame fixed to one side of the top of the base frame and a second Z-axis cylinder mounted on one side of the surface of the mountain-shaped guide frame. The top of the piston rod of the second Z-axis cylinder is fixedly connected to one side of the outer wall of the inverted U-shaped hollow frame.

[0011] Preferably, guide arms are fixed on both sides of the bottom end of the inverted U-shaped hollow frame, and the bottom end of the guide arms extends into the interior of the mountain-shaped guide frame.

[0012] Preferably, the roller-sweeping multi-point self-rotating cleaning module includes longitudinally placed cleaning rollers rotatably mounted on the left and right sides of the bottom end of an inverted U-shaped hollow frame, right-angle shaft frames fixed inside the inverted U-shaped hollow frame on both sides, a secondary drive shaft rotatably mounted inside the right-angle shaft frames, and a gear transmission structure for maintaining power transmission installed at the same end of the two secondary drive shafts. A vertical shaft is rotatably mounted on the top of the right-angle shaft frame, and a bevel gear transmission structure for maintaining power connection is installed between the vertical shaft and the secondary drive shaft. An umbrella-shaped brush roller is fixed to the top of the vertical shaft, and a pulley transmission structure for maintaining power transmission is installed between the longitudinally placed cleaning rollers.

[0013] Preferably, a stepper motor for driving one of the longitudinal cleaning rollers to rotate is installed on one side of the surface of the inverted U-shaped hollow frame, and the output end of the stepper motor and one end of the longitudinal cleaning roller are connected to each other by a coupling.

[0014] Preferably, the bevel gear transmission structure includes a driven bevel gear fixed at the bottom end of the vertical shaft and a driving bevel gear fixed at one end of the surface of the auxiliary transmission shaft. The driven bevel gear and the driving bevel gear mesh with each other, and three umbrella-shaped brush rollers are arranged on the same Y-axis extension line.

[0015] This invention also provides a cleaning method for producing preserved eggs, using the preserved egg production cleaning equipment described above, comprising the following steps:

[0016] S101: A rinsing spray device is arranged above the equipment. The rinsing spray device sprays cleaning liquid downwards. Several preserved eggs to be cleaned are placed in the egg tray assembly until the egg tray assembly is full of preserved eggs. The lifting egg tray limits each preserved egg in the egg tray assembly to ensure that the preserved eggs do not move during the cleaning process.

[0017] S102: The cleaning fluid from the rinsing spray device is sprayed under high pressure to rinse the upper part of the preserved egg first;

[0018] S103: The lifting unit allows the inverted U-shaped hollow frame and the roller-sweeping multi-point self-rotating cleaning module to actively approach the preserved egg, and makes the cleaning end of the roller-sweeping multi-point self-rotating cleaning module contact the lower half of the preserved egg. At this time, the cleaning liquid in the upper half of the preserved egg will flow to the lower half of the preserved egg. Multiple cleaning brushes in the roller-sweeping multi-point self-rotating cleaning module rotate in a multi-point manner, contact the lower surface of the preserved egg and perform scrubbing.

[0019] S104: After a period of cleaning, the flipping module causes the square vertical arm, the lower egg tray assembly, and the upper lifting egg tray to rotate 180 degrees, so that the upper part of the preserved egg turns to the bottom and the lower part turns to the top. The lifting unit causes the roller-sweeping multi-point self-rotating cleaning module to contact the preserved egg again and scrub the lower surface of the preserved egg until the cleaning work is completed.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The preserved egg production and cleaning equipment and its cleaning method have a rinsing device arranged above the equipment. When the rinsing device sprays cleaning liquid downwards, the lifting and raising unit brings the inverted U-shaped hollow frame and the roller-sweeping multi-point self-rotating cleaning module closer to the preserved egg, causing the roller-sweeping multi-point self-rotating cleaning module to contact the lower surface of the preserved egg. At this time, the upper part of the preserved egg is rinsed, while the lower part is scrubbed. After the preserved egg has been cleaned for a period of time, the flipping module causes the upper lifting egg tray and lower egg tray assembly to rotate 180 degrees, and the cleaning continues. The lifting and raising unit allows... The roller-sweeping multi-point self-rotating cleaning module contacts the lower surface of the preserved egg, while the rinsing device sprays cleaning fluid, achieving the purpose of cleaning both the upper and lower surfaces of the preserved egg. This combined cleaning method ensures the uniformity of cleaning the preserved egg surface, avoiding the cleaning blind spots and uneven cleaning problems existing in traditional cleaning methods. The preserved egg can be automatically flipped during the cleaning process without manual intervention, improving cleaning efficiency and saving labor costs. Furthermore, the design of the roller-sweeping multi-point self-rotating cleaning module allows the cleaning brush to cover multiple points on the surface of the preserved egg, thereby achieving all-round cleaning and ensuring the thorough cleaning of the preserved egg.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Example 1, by Figures 1 to 4 The present invention includes a base frame 1, with a transmission box 2 and a second shaft frame 101 fixed on both sides of the top of the base frame 1 respectively. A square-mouthed longitudinal arm 5 is rotatably mounted on the outer wall of the opposite side of the transmission box 2 and the base frame 1. An egg tray assembly 6 is fixed between the two square-mouthed longitudinal arms 5. An upward lifting egg tray 7 for limiting the preserved egg together with the egg tray assembly 6 is installed inside one of the square-mouthed longitudinal arms 5. A face-changing flipping module 4 for driving the square-mouthed longitudinal arm 5, the egg tray assembly 6, and the upward lifting egg tray 7 to rotate is installed inside the transmission box 2.

[0032] The lifting and raising unit 8 is installed on the top of the base frame 1. The movable end of the lifting and raising unit 8 is equipped with a roller-sweeping multi-point self-rotating cleaning module 9. The roller-sweeping multi-point self-rotating cleaning module 9 is installed inside to clean the lower half of the preserved eggs in the lower egg tray assembly 6. A PLC controller 3 is installed on one side of the outer wall of the transmission box 2. The output end of the PLC controller 3 is electrically connected to the input end of the flipping module 4, the upper lifting egg tray 7, the lifting and raising unit 8, and the roller-sweeping multi-point self-rotating cleaning module 9.

[0033] The rinsing spray device (not shown) mainly consists of spray heads, a water supply system, a control device, and a spray frame. The spray heads have multiple small holes inside to spray fine water jets. The water supply system includes a water pump, water pipes, valves, etc., and is used to supply cleaning fluid to the spray heads and maintain a certain pressure. The control device is used to adjust the spray pressure and flow rate of the spray heads to adapt to different cleaning needs. The spray frame supports the spray heads, allowing them to cover all parts of the object to be cleaned. When the device is started, the water pump draws cleaning fluid from the water source to the spray heads, which then spray fine water jets to evenly cover the surface of the object to be cleaned.

[0034] This embodiment describes a cleaning method for producing preserved eggs, using the aforementioned preserved egg production cleaning equipment, which includes the following steps:

[0035] S101: A rinsing spray device is arranged above the equipment. The rinsing spray device sprays cleaning liquid downwards. Several preserved eggs to be cleaned are placed in the egg tray assembly 6 until the egg tray assembly 6 is full of preserved eggs. The lifting egg tray 7 limits each preserved egg in the egg tray assembly 6 to ensure that the preserved eggs will not move during the cleaning process.

[0036] S102: The cleaning fluid from the rinsing spray device is sprayed under high pressure to rinse the upper part of the preserved egg first;

[0037] S103: The lifting unit 8 causes the inverted U-shaped hollow frame 10 and the roller-type multi-point self-rotating cleaning module 9 to actively approach the preserved egg, and causes the cleaning end of the roller-type multi-point self-rotating cleaning module 9 to contact the lower half of the preserved egg. At this time, the cleaning liquid in the upper half of the preserved egg will flow to the lower half of the preserved egg. Multiple cleaning brushes in the roller-type multi-point self-rotating cleaning module 9 rotate in a multi-point manner, contact the lower surface of the preserved egg and perform scrubbing.

[0038] S104: After a period of cleaning, the flipping module 4 causes the square vertical arm 5, the lower egg tray assembly 6, and the upper lifting egg tray 7 to rotate 180 degrees, so that the upper part of the preserved egg turns to the bottom and the lower part turns to the top. The lifting unit 8 causes the roller-sweeping multi-point self-rotating cleaning module 9 to contact the preserved egg again and wipe the lower surface of the preserved egg until the cleaning work is completed.

[0039] Example 2, based on Example 1, is... Figure 5 and Figure 6 The upper lifting egg tray 7 includes a rectangular cutting cavity disposed inside one of the square longitudinal arms 5, a first Z-axis cylinder 701 installed inside the rectangular cutting cavity, and an upper egg tray assembly 702 fixed to the top of the piston rod of the first Z-axis cylinder 701. The upper egg tray assembly 702 and the lower egg tray assembly 6 have the same structure.

[0040] When the preserved eggs are placed in the lower egg tray assembly 6 and the upper lifting egg tray 7 of the device, the preserved eggs are placed in the lower egg tray assembly 6. The first Z-axis cylinder 701 is activated by the PLC controller 3, so that the first Z-axis cylinder 701 actively drives the upper egg tray assembly 702 to move down. The preserved eggs are then clamped by the upper egg tray assembly 702 and the lower egg tray assembly 6. Through limiting and fixing, each preserved egg can maintain the same position and angle during the cleaning process, ensuring that each preserved egg receives a uniform cleaning action. This helps to eliminate the problem of uneven cleaning caused by the position deviation of the preserved eggs, thereby improving the overall cleaning quality. Moreover, because the position of the preserved eggs can be firmly maintained, the damage of the preserved eggs caused by shaking or collision during the cleaning process is reduced, thus reducing the damage rate of the preserved eggs.

[0041] The egg tray assembly 702 includes a plate tray 7021 fixed to the top of the first Z-axis cylinder 701, several conical support rings 7022 arrayed at the bottom of the plate tray 7021, and an arc-shaped hollow groove 7023 on the outer circumference of the conical support rings 7022. The outer diameter of the conical support rings 7022 gradually decreases from one end near the plate tray 7021 to the other end. The structural design of the plate tray 7021 allows the preserved eggs to be evenly distributed, ensuring that each preserved egg has enough space and avoiding mutual compression. The shape of the plate tray 7021 matches the shape of the preserved eggs, allowing the preserved eggs to be firmly placed in the support rings and remain stable whether in a static state or during the movement of the cleaning equipment. The arc-shaped hollow groove 7023 allows part of the preserved egg to be suspended and exposed, thereby allowing the cleaning fluid to flow during the cleaning process and allowing the roller-type multi-point self-rotating cleaning module 9 to contact the preserved eggs while keeping the preserved eggs fixed.

[0042] The flipping module 4 includes a gear reduction drive unit 401 mounted on the inner wall of one side of the transmission box 2 and a turntable 402 rotatably mounted on the outer wall of one side of the transmission box 2. The gear reduction drive unit 401 drives the turntable 402 to rotate. One of the square-shaped longitudinal arms 5 is fixed to the outer wall of one side of the turntable 402. A right-angle seat is welded to the top of the square-shaped longitudinal arm 5. An inverted right-angle seat is fixed to the outer wall of one side of the turntable 402. The right-angle seat and the inverted right-angle seat are bolted to each other. When flipping the lower egg tray assembly 6, the upper lifting egg tray 7, and the preserved egg, the gear reduction drive unit 401 drives the turntable 402 and the square-shaped longitudinal arm 5 to rotate. The gear reduction drive unit 401 provides precise speed control and high-efficiency power conversion through gear transmission to ensure that the flipping module 4 rotates smoothly and evenly and that the preserved egg remains stable during the flipping process.

[0043] Example 3, based on Example 2, by Figure 7 and Figure 8 The lifting unit 8 includes a mountain-shaped guide frame 801 fixed to one side of the top of the base frame 1 and a second Z-axis cylinder 802 mounted on one side of the surface of the mountain-shaped guide frame 801. The top of the piston rod of the second Z-axis cylinder 802 is fixedly connected to one side of the outer wall of the inverted U-shaped hollow frame 10. When the lifting unit 8 is working, the second Z-axis cylinder 802 drives the inverted U-shaped hollow frame 10 and the rolling sweeping multi-point self-rotating cleaning module 9 to move up and down. By controlling the height of the cleaning module, it can be ensured that the cleaning module is in full contact with the lower half of the preserved egg, thereby improving the cleaning efficiency and removing stains and residues from the surface of the preserved egg.

[0044] Guide arms 1001 are fixed on both sides of the bottom end of the inverted U-shaped hollow frame 10. The bottom end of the guide arm 1001 extends into the interior of the mountain-shaped guide frame 801. During the up and down adjustment of the inverted U-shaped hollow frame 10, the guide arm 1001 will slide inside the mountain-shaped guide frame 801. The guide arm 1001 and the mountain-shaped guide frame 801 improve the lifting stability of the inverted U-shaped hollow frame 10 and the rolling sweeping multi-point self-rotating cleaning module 9.

[0045] The multi-point self-rotating cleaning module 9 includes a longitudinally placed cleaning roller 907 rotatably mounted on the left and right sides of the bottom end of the inverted U-shaped hollow frame 10, a right-angle shaft frame 901 fixed inside both sides of the inverted U-shaped hollow frame 10, a secondary drive shaft 902 rotatably mounted inside the right-angle shaft frame 901, and a gear transmission structure 903 for maintaining power transmission mounted at the same end of the two secondary drive shafts 902. A vertical shaft 904 is rotatably mounted on the top of the right-angle shaft frame 901. A bevel gear transmission structure 905 for maintaining power connection is installed between the vertical shaft 904 and the secondary drive shaft 902. The bevel gear transmission structure 905 includes a driven bevel gear fixed at the bottom end of the vertical shaft 904 and a driving bevel gear fixed at one end of the surface of the secondary drive shaft 902. The driven bevel gear and the driving bevel gear mesh with each other.

[0046] An umbrella-shaped brush roller 906 is fixed to the top of the vertical shaft 904. Three umbrella-shaped brush rollers 906 are arranged along the same Y-axis extension line. A belt drive structure 908 for maintaining power transmission is installed between the longitudinal cleaning rollers 907. A stepper motor 909 for driving one of the longitudinal cleaning rollers 907 is installed on one side of the surface of the inverted U-shaped hollow frame 10. The output end of the stepper motor 909 and one end of the longitudinal cleaning roller 907 are connected to each other through a coupling. When the roller-sweeping multi-point self-rotating cleaning module 9 approaches the lower half of the preserved egg, the stepper motor 909... The rotational power of 09 will be transmitted to one of the longitudinal cleaning rollers 907. At this time, the longitudinal cleaning roller 907 will drive the auxiliary drive shaft 902 to rotate through the pulley drive structure 908. The two auxiliary drive shafts 902 are connected by the gear drive structure 903. Then, the auxiliary drive shaft 902 drives the vertical shaft 904 and the umbrella-shaped brush roller 906 to rotate through the bevel gear drive structure 905. During this process, the longitudinal cleaning roller 907 wipes the preserved eggs placed on both sides of the egg tray assembly 6, while the umbrella-shaped brush roller 906 wipes the preserved eggs it contacts by rotating on its own.

[0047] The rotating motion of multiple cleaning points can quickly cover the surface of the preserved egg, removing stains and residues. At the same time, the rotating motion of the module can generate centrifugal force, which helps to separate stains from the surface of the preserved egg, further improving cleaning efficiency. In addition, the downward flow of cleaning liquid further promotes the removal of lime and grass ash from the surface of the preserved egg.

[0048] In this embodiment, the operator first installs a rinsing spray device above the equipment, which sprays cleaning fluid downwards. Then, the operator places several preserved eggs to be cleaned into the egg tray assembly 6 until it is full. At this point, the operator can activate the lifting egg tray 7 via the PLC controller 3. The lifting egg tray 7 limits the movement of each preserved egg in the egg tray assembly 6, ensuring that the eggs do not move during the cleaning process, thus guaranteeing the accuracy of the cleaning and the preservation of the eggs. For safety, when cleaning begins, the PLC controller 3 starts and sends signals to other components to coordinate their operation. Specifically, the cleaning fluid from the rinsing spray device is sprayed under high pressure, first rinsing the upper half of the preserved egg. Simultaneously, the lifting unit 8 starts operating, causing the inverted U-shaped perforated frame 10 and the multi-point rotating cleaning module 9 to actively approach the preserved egg, bringing the cleaning end of the multi-point rotating cleaning module 9 into contact with the lower half of the preserved egg. At this point, the cleaning fluid from the upper half of the preserved egg flows to the lower half. The cleaning fluid from the multi-point rotating cleaning module 9... Multiple cleaning brushes rotate at multiple points, contacting and scrubbing the lower surface of the preserved egg. This structural design ensures effective cleaning of the lower half of the preserved egg. After a period of cleaning, the lifting unit 8 moves the roller-sweeping multi-point rotating cleaning module 9 and the inverted U-shaped hollow frame 10 downwards, creating space for the flipping module 4, the square vertical arm 5, the lower egg tray assembly 6, and the upper lifting egg tray 7 to rotate. The lower egg tray assembly 6 then controls the flipping module 4 to rotate, causing the square vertical arm 5, the lower egg tray assembly 6, and the upper lifting egg tray 7 to rotate 180 degrees, thus cleaning the preserved egg. The upper part rotates to the bottom, and the lower part rotates to the top. After flipping, the PLC controller 3 controls the rinsing spray device to start working again, and the cleaning liquid is sprayed onto the upper part of the preserved egg. At the same time, the lifting unit 8 makes the roller-sweeping multi-point self-rotating cleaning module 9 contact the preserved egg again to scrub the lower surface of the preserved egg. After a period of cleaning, the PLC controller 3 stops the operation of all components. At this time, the upper lifting egg tray 7 will actively move away from the lower egg tray assembly 6, and the staff will take the cleaned preserved egg out of the egg tray. If necessary, subsequent drying or other processing procedures can be carried out.
