[0003] When operators apply a coating to the surface of preserved eggs for preservation, the coating is often done manually. This method increases the labor intensity of the operators, which may reduce the efficiency of the coating and may also cause uneven coating on the surface, thus reducing the quality of the coating. Summary of the Invention

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This type of preserved egg production and processing coating and preservation equipment involves the operator placing the preserved eggs inside the egg tray during daily use. The operator then starts the regulating motor, which causes the rotating shaft to rotate. This rotating shaft drives the sprocket to rotate, which in turn drives the chain to rotate on its surface. The chain then drives the connecting block to slide, which in turn drives the moving plate to slide. Simultaneously, the moving plate causes the egg tray and the preserved eggs inside to slide until they are placed inside the coating chamber. The operator then starts the rotary motor, which rotates the egg tray, thus rotating the preserved eggs for coating. This reduces the operator's workload and improves coating efficiency.
[0013] This type of equipment for coating and preserving preserved eggs involves the operator placing edible liquid paraffin into a constant-temperature material tank through the feed pipe. The operator then starts a self-heating pump, which draws the liquid paraffin from the tank through a connecting pipe. The liquid paraffin flows into the vertical pipe and then into the storage box. Finally, it is sprayed onto the surface of the preserved eggs through nozzles. This method ensures the liquid paraffin is evenly applied to the eggs, resulting in a more uniform wax film thickness and improving the coating quality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution: a coating and preservation device for processing preserved eggs, comprising a base plate 1, with vertical plates 2 fixedly installed at both ends of the top of the base plate 1. Sprockets 3 are rotatably mounted at equal intervals on opposite surfaces of the vertical plates 2. Chains 4 are movably fitted onto the surfaces of the sprockets 3. When the sprockets 3 rotate, they drive the chains 4 to rotate on their surfaces, thereby adjusting the position of the connecting block 7. A rotating shaft 5 is rotatably installed between the vertical plates 2, with its outer surface fixedly connected to the inner surface of the sprockets 3. When the rotating shaft 5 rotates, it drives the sprockets 3 to rotate, thereby driving the chains 4 to rotate. An adjusting motor 6 is fixedly installed at one end of each vertical plate 2. The output end of the adjusting motor 6 passes through the vertical plate 2 and is fixedly connected to one end of the rotating shaft 5. When the adjusting motor 6 operates, it causes the rotating shaft 5 to rotate, thereby improving the adjustment efficiency of the sprockets 3. Connecting blocks 7 are fixedly installed at the top of the chain 4, and movable plates 8 are fixedly installed between the connecting blocks 7. When the chain 4 rotates, it will cause the connecting blocks 7 to slide, which in turn will cause the movable plates 8 to slide. Egg trays 9 are rotatably installed at equal distances on the top of the movable plates 8. Egg trays 9 can hold preserved eggs. When the movable plates 8 slide, they will cause the egg trays 9 to slide. Rotary motors 10 are fixedly installed at equal distances on the bottom of the movable plates 8, and the output end of the rotary motors 10 passes through the movable plates 8 and is fixedly connected to the bottom of the egg trays 9. When the rotary motors 10 are running, they will cause the egg trays 9 to rotate, which will cause the preserved eggs to rotate. A coating chamber 11 is fixedly installed on the top of the base plate 1, and a constant temperature material box 12 is fixedly installed on the top of the coating chamber 11. The constant temperature material box 12 can store liquid paraffin and keep it at a constant temperature.
[0021] A feed pipe 13 is fixedly installed on the top of the constant temperature material tank 12, and the bottom of the feed pipe 13 penetrates the constant temperature material tank 12 and extends to the inner surface of the constant temperature material tank 12. Edible liquid paraffin can be placed inside the constant temperature material tank 12 through the feed pipe 13. Fixed plates 14 are fixedly installed at both ends of the top of the coating chamber 11. A storage box 15 is fixedly installed at the bottom of the fixed plates 14. Due to the design of the fixed plates 14, the storage box 15 is more stable and can store liquid paraffin. Spray nozzles 16 are fixedly installed at equal intervals at the bottom of the storage box 15, and the top of the spray nozzles 16 penetrates the storage box 15 and extends to the inner surface of the storage box 15. The liquid paraffin inside the storage box 15 will be sprayed onto the surface of the preserved egg through the spray nozzles 16, thereby coating it. A self-heating and heat-preserving pump 17 is fixedly installed on the top of the coating chamber 11. A vertical pipe 18 is fixedly installed at the bottom of the base plate 7. The bottom of the vertical pipe 18 passes through the coating chamber 11 and the storage box 15 and extends to the inner surface of the storage box 15. When the self-heating and heat-preserving pump 17 is running, it will place liquid paraffin inside the storage box 15 through the vertical pipe 18. A connecting pipe 19 is fixedly installed at one end of the self-heating and heat-preserving pump 17, and one end of the connecting pipe 19 passes through the constant temperature material box 12 and extends to the inner surface of the constant temperature material box 12. When the self-heating and heat-preserving pump 17 is running, it will draw liquid paraffin inside the constant temperature material box 12 through the connecting pipe 19 and circulate it. A drying chamber 20 located on the right side of the coating chamber 11 is fixedly installed at the top of the base plate 1. Both ends of the drying chamber 20 are fixedly installed with blower dryers 21. The design of the drying chamber 20 and the blower dryers 21 can accelerate the drying of paraffin on the surface of the preserved egg, thereby accelerating the coating efficiency.
[0022] Working principle: First, the operator places edible liquid paraffin into the constant temperature material box 12 through the feed pipe 13. Then, the preserved egg is placed inside the egg tray 9. The regulating motor 6 is then started. The operation of the regulating motor 6 causes the rotating shaft 5 to rotate. At this time, the rotating shaft 5 drives the sprocket 3 to rotate, which in turn drives the chain 4 to rotate on its surface. Subsequently, the chain 4 drives the connecting block 7 to slide, which in turn drives the moving plate 8 to slide. Simultaneously, the moving plate 8 drives the egg tray 9 and the preserved egg inside to slide until it is placed inside the coating chamber 11. Then, the rotary motor 10 is started to rotate... The operation of motor 10 causes egg tray 9 to rotate, and then the self-heating heat preservation pump 17 is started. The operation of self-heating heat preservation pump 17 draws liquid paraffin from the constant temperature material box 12 through connecting pipe 19. At this time, the liquid paraffin flows into the interior of vertical pipe 18, and then enters the interior of storage box 15. It is then sprayed onto the surface of preserved eggs through nozzle 16 to complete the coating work. At the same time, the moving plate 8 and egg tray 9 continue to move the preserved eggs into the drying chamber 20, and then the blower dryer 21 is started. The operation of blower dryer 21 can accelerate the drying of liquid paraffin on the surface of preserved eggs.
