Description

Technical Field

[0001] The invention relates to the technical field of preserved egg production, and in particular to preserved egg production cleaning equipment and a cleaning method thereof. Background Art

[0002] The main function of the preserved egg cleaning equipment is to remove the lime and grass ash on the outer layer of the preserved egg shell to ensure the hygiene and beauty of the preserved egg. During the production process of preserved eggs, after the yeast fermentation period, a layer of lime and grass ash will adhere to the surface of the eggshell. These substances not only affect the appearance of the preserved egg, but may also contain bacteria and impurities. This type of preserved egg cleaning equipment is mainly composed of a cleaning tank, a cleaning water circulation system, a cleaning nozzle and a cleaning control system. The cleaning tank is the main part, which is used to hold the preserved eggs and clean them. The cleaning water circulation system includes a water pump, a water tank and a pipe, which is responsible for providing cleaning water and keeping the cleaning water clean. The cleaning nozzle is installed on the top of the cleaning tank to spray the cleaning water evenly onto the surface of the preserved egg. The cleaning control system includes a control panel, sensors and actuators to operate the equipment and monitor the cleaning process. The structural principle is to utilize a cleaning water circulation system and a cleaning nozzle to remove the lime soil and grass ash on the surface of the preserved eggs through the power of high-pressure water flow; as disclosed in the authorization announcement number CN117426329A, a preserved egg production cleaning device includes a bottom plate and a water storage tank, a support tube is provided at the upper end of the bottom plate, a preserved egg conveyor belt is fixedly installed at one end of the support tube, a plurality of elliptical holes are provided on the surface of the preserved egg conveyor belt, two water storage tanks are provided, a pipeline is fixedly installed at the upper end of the water storage tank, a driving motor is provided at the upper end of the water storage tank, a rotating shaft is fixedly connected to the output end of the driving motor, and a rotating shaft is fixedly connected to the surface of the rotating shaft with a first bevel gear. The meshing second bevel gear is provided with an elliptical hole at the upper end of the preserved egg conveyor belt, so that the preserved eggs can be fixed on the preserved egg conveyor belt for easy cleaning. By arranging cleaning equipment and nozzles on the lower surface of the pipeline, the preserved eggs enter the preserved egg conveyor belt and are washed by the corresponding cleaning equipment. However, during the implementation of the above technical scheme, the preserved eggs to be washed are located in the elliptical holes of the conveyor belt. Since the nozzle sprays the cleaning liquid from top to bottom, the preserved eggs located on the inner side of the conveyor belt will be difficult to be sprayed and rinsed, thereby forming a part of the cleaning blind area. The uneven cleaning effect will cause some areas on the surface of the preserved eggs to still have lime soil and grass ash remaining, affecting the hygiene and appearance quality of the preserved eggs. At this time, only repeated washing can be carried out. Summary of the invention

When the device is started, the water pump pumps the cleaning liquid from the water source to the spray head, and the spray head sprays fine water columns to evenly cover the surface of the object to be cleaned.

[0019] A method for cleaning preserved eggs produced in this embodiment, such as the above-mentioned preserved egg cleaning equipment, comprises the following steps: S101: a flushing spray device is arranged above the equipment, and the flushing spray device sprays a cleaning liquid downward to uniformly place a plurality of preserved eggs to be cleaned in the egg tray assembly 6 until the egg tray assembly 6 is full of preserved eggs, and the upper lifting egg tray 7 limits each preserved egg in the egg tray assembly 6 to ensure that the preserved eggs do not move during the cleaning process; S102: The cleaning liquid of the flushing spray device is sprayed at high pressure to first flush the upper part of the preserved egg; S103: The lifting and lowering unit 8 makes the inverted U-shaped hollow frame 10 and the rolling sweeping type multi-point self-spinning cleaning module 9 actively approach the preserved egg, and makes the cleaning end of the rolling sweeping type multi-point self-spinning cleaning module 9 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, and the multiple cleaning brushes in the rolling sweeping type multi-point self-spinning cleaning module 9 will spin in a multi-point manner, contact the lower surface of the preserved egg and scrub it; S104: After a period of cleaning, the face-changing flipping module 4 flips the square-mouthed longitudinal arm 5, the lower egg tray assembly 6, and the upper lifting egg tray 7 180 degrees, so that the upper half of the preserved egg turns downward and the lower half turns upward, and the lifting and lifting unit 8 makes the rolling sweeping multi-point self-spinning cleaning module 9 contact the preserved egg again to scrub the lower surface of the preserved egg until the cleaning work is completed.

[0020] Embodiment 2, based on embodiment 1, Figure 5 and Figure 6 It is shown that the upper lifting egg tray 7 includes a rectangular cut-out cavity arranged inside one of the square-mouth longitudinal arms 5, a first Z-axis cylinder 701 installed inside the rectangular cut-out cavity, and an upper egg tray assembly 702 fixed to the top end of the piston rod of the first Z-axis cylinder 701, and the upper egg tray assembly 702 and the lower egg tray assembly 6 have the same structure; When the preserved eggs are arranged 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, and the first Z-axis cylinder 701 is turned on by the PLC controller 3 to work, so that the first Z-axis cylinder 701 actively drives the upper egg tray assembly 702 to move downward, and the preserved eggs are 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 is evenly cleaned, which helps to eliminate the problem of uneven cleaning caused by the position deviation of the preserved eggs, thereby improving the overall cleaning quality, and 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, and the damage rate of the preserved eggs is reduced; The upper egg tray assembly 702 includes a plate tray 7021 fixed on the top of the first Z-axis cylinder 701, a plurality of conical support rings 7022 arrayed at the bottom of the plate tray 7021, and an arc-shaped hollow groove 7023 arranged on the outer peripheral surface of the conical support ring 7022. The outer diameter of the conical support ring 7022 gradually decreases from one end close to 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 to avoid mutual squeezing. The plate tray 7021 matches the shape of the preserved eggs, so that the preserved eggs can be firmly placed in the support ring, and can remain stable whether in a stationary state or during the movement of the cleaning device. The arc-shaped hollow groove 7023 allows a part of the preserved eggs to be suspended and exposed, thereby allowing the cleaning liquid to flow during the cleaning process and allowing the rolling sweep type multi-point self-spinning cleaning module 9 to contact the preserved eggs while keeping the preserved eggs fixed; The face-changing and flipping module 4 includes a gear reduction drive unit 401 installed on the inner wall of one side of the transmission box 2 and a turntable 402 rotatably installed on the outer wall of one side of the transmission box 2. The gear reduction drive unit 401 is used to drive the turntable 402 to rotate. One of the square longitudinal arms 5 is fixed on the outer wall of one side of the turntable 402. A right angle seat is welded on the top of the square longitudinal arm 5. An inverted right angle seat is fixed on 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 the lower egg tray assembly 6, the upper lifting egg tray 7 and the preserved egg are turned over, the turntable 402 and the square longitudinal arm 5 are driven by the gear reduction drive unit 401 to rotate. The gear reduction drive unit 401 provides precise speed control and efficient power conversion through gear transmission, ensuring that the face-changing and flipping module 4 rotates smoothly and evenly, and ensuring that the preserved egg remains stable during the flipping process.

[0021] Embodiment 3, based on embodiment 2, Figure 7 and Figure 8 It is given that the lifting and lowering 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 installed 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 the outer wall of one side of the inverted U-shaped hollow frame 10. When the lifting and lowering 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-spinning 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 on the surface of the preserved egg. Guide arms 1001 are fixed on both sides of the bottom of the inverted U-shaped hollow frame 10, and the bottom ends of the guide arms 1001 extend to the inside of the mountain-shaped guide frame 801. During the up and down debugging process of the inverted U-shaped hollow frame 10, the guide arms 1001 will slide inside the mountain-shaped guide frame 801, and the lifting stability of the inverted U-shaped hollow frame 10 and the rolling sweep type multi-point self-spinning cleaning module 9 is improved by the guide arms 1001 and the mountain-shaped guide frame 801; The rolling sweeping multi-point self-spinning cleaning module 9 includes a longitudinal 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 on both sides of the inside of the inverted U-shaped hollow frame 10, a secondary transmission shaft 902 rotatably mounted inside the right-angle shaft frame 901, and a pair of gear transmission structures 903 for maintaining power transmission installed at the same end of the two secondary transmission shafts 902, a vertical shaft 904 is rotatably mounted on the top of the right-angle shaft frame 901, and a bevel gear transmission structure 905 for maintaining power connection is installed between the vertical shaft 904 and the secondary transmission shaft 902, and 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 transmission shaft 902, and the driven bevel gear and the driving bevel gear are meshed with each other; An umbrella-shaped brush roller 906 is fixed to the top of the vertical shaft 904, and three umbrella-shaped brush rollers 906 are arranged on the same Y-axis extension line. A pulley transmission structure 908 for maintaining power transmission is installed between the longitudinal cleaning rollers 907 and the longitudinal cleaning rollers 907. A stepper motor 909 for driving one of the longitudinal cleaning rollers 907 to rotate 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 rolling sweeping multi-point self-spinning cleaning module 9 approaches the lower half of the preserved egg, the stepper motor 9 09's rotational power will be transmitted to one of the longitudinal cleaning rollers 907, at which time the longitudinal cleaning roller 907 will drive the secondary transmission shaft 902 to rotate through the pulley transmission structure 908, and the two secondary transmission shafts 902 will maintain power connection through the gear transmission structure 903, and then the secondary transmission shaft 902 will drive the vertical shaft 904 and the umbrella-shaped brush roller 906 to rotate through the bevel gear transmission structure 905. In this process, the longitudinal cleaning roller 907 scrubs the preserved eggs placed on both sides of the lower egg tray assembly 6, and the umbrella-shaped brush roller 906 scrubs the preserved eggs it contacts by rotating. Through the rotational movement of multiple cleaning points, the surface of the preserved egg can be quickly covered to remove stains and residues. At the same time, the rotational movement of the module can generate centrifugal force to help separate stains from the surface of the preserved egg, further improving the cleaning efficiency, and cooperating with the downward flowing cleaning liquid, further promoting the peeling of lime soil and grass ash on the surface of the preserved egg.

[0022] When the embodiment of the present application is in use, first, the staff arranges a flushing spray device above the equipment, and the flushing spray device sprays the cleaning liquid downward, so that the cleaning liquid is sprayed from top to bottom, and then the staff uniformly places a number of preserved eggs to be cleaned in the egg tray assembly 6, until the egg tray assembly 6 is full of preserved eggs, and then the staff can start the upper lifting egg tray 7 through the PLC controller 3 to work, and the upper 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, thereby ensuring the accuracy of cleaning and the quality of the preserved eggs. Safety, when cleaning starts, the PLC controller 3 starts and sends signals to other components to coordinate the work of each component, that is, the cleaning liquid of the flushing spray device is sprayed through high pressure to flush the upper part of the preserved egg first. While spraying, the lifting and lifting unit 8 starts to work, which makes the inverted U-shaped hollow frame 10 and the rolling and sweeping multi-point self-spinning cleaning module 9 actively approach the preserved egg, and makes the cleaning end of the rolling and sweeping multi-point self-spinning cleaning module 9 contact with the lower part of the preserved egg. At this time, the cleaning liquid in the upper part of the preserved egg will flow to the lower part of the preserved egg, and the rolling and sweeping multi-point self-spinning cleaning module 9 will contact with the lower part of the preserved egg. The multiple cleaning brushes rotate in a multi-point manner, contact with and scrub the lower surface of the preserved egg. This structural design ensures the cleaning effect of the lower half of the preserved egg. After a period of cleaning, the lifting and lifting unit 8 drives the rolling sweeping multi-point self-spinning cleaning module 9 and the inverted U-shaped hollow frame 10 to move downward, reserving space for the flipping of the face-changing and turning module 4, the square-mouthed longitudinal arm 5, the lower egg tray assembly 6, and the upper lifting egg tray 7. Then the lower egg tray assembly 6 controls the face-changing and turning module 4 to move, so that the square-mouthed longitudinal arm 5, the lower egg tray assembly 6, and the upper lifting egg tray 7 are flipped 180 degrees, so that the preserved egg The upper part turns downward and the lower part turns upward. After turning over, the PLC controller 3 controls the flushing and spraying device to start working again, and the cleaning liquid sprays the upper part of the preserved egg. At the same time, the lifting and lifting unit 8 makes the sweeping multi-point self-spinning cleaning module 9 contact the preserved egg again and scrub the lower surface of the preserved egg. After a period of cleaning again, 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 eggs out of the egg tray. If necessary, subsequent drying or other processing steps can be carried out.
