Description

Technical Field

[0001] This utility model relates to the technical field of sea duck egg production and testing equipment, specifically a sea duck egg crack inspection device for turning eggs. Background Technology

[0002] As a highly nutritious food, the quality testing of sea duck eggs is particularly important. During the process of making salted duck eggs from sea duck eggs, cracks are a common quality problem. Cracks not only affect the appearance of the egg but can also lead to bacterial invasion, affecting the egg's safety for consumption and its shelf life.

[0003] Currently, crack detection in sea duck eggs mainly relies on manual light inspection, which involves shining a light on the eggshell to observe for cracks. However, manual light inspection suffers from low efficiency, high labor intensity, and low detection accuracy. Especially when it is necessary to turn the egg over to fully inspect for cracks, manual operation is not only time-consuming but also prone to damaging the egg due to improper handling.

[0004] To improve the efficiency and accuracy of crack detection in sea duck eggs, a device is needed that can automatically flip the egg and work in conjunction with light inspection to achieve efficient and accurate crack detection. Utility Model Content

[0005] The purpose of this invention is to provide an egg-turning device for detecting cracks in sea duck eggs using a light, so as to solve the problems mentioned in the background art.

[0008] Preferably, the egg-turning mechanism includes telescopic cylinders disposed at both ends of the frame, a clutch frame connected to a telescopic rod of the telescopic cylinders, and a transmission belt rotatably disposed in the clutch frame. The transmission belt is driven by a drive motor to rotate cyclically, and the extension movement of the telescopic cylinders causes the transmission belt to press against the rollers to achieve friction transmission.

[0009] Preferably, the telescopic cylinder is a pneumatic cylinder, which is connected to a pneumatic generator, and the pneumatic cylinder has a certain compressibility to reduce transmission damage.

[0010] Preferably, the outer surface of the transmission belt is textured, and the corresponding transmission contact parts of the rollers are knurled to increase transmission friction.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] like Figures 1 to 5 As shown, this utility model is an egg-turning device for detecting cracks in sea duck eggs using a light, used to assist in the manual detection of cracks in sea duck eggs. Specifically, the egg-turning device includes a frame 1, which is installed on a base frame 3 fixed to the ground via connectors 2. At least two chains 4, preferably two chains 4, are installed in the frame 1 and rotate synchronously. Multiple evenly distributed round rods 5 are fixedly connected between the chains 4, and several evenly distributed rollers 6 are rotatably arranged in the round rods 5. The rollers 6 have a rotating structure that is thinner in the middle and thicker at both ends, effectively preventing the egg from slipping during the turning process. An illumination device 7 is provided in the frame 1, located between the upper and lower chains 4 and shining upwards to ensure that cracks in the translucent eggshell can be clearly observed. An egg-turning mechanism 8 is also provided in the frame 1, which is disengaged and driven by the rollers 6 to achieve flexible egg-turning.

[0025] More specifically, such as Figure 3 and Figure 4 As shown, the egg-turning mechanism 8 includes telescopic cylinders 9 disposed at both ends of the frame 1, a clutch frame 10 connected to the telescopic rod of the telescopic cylinders 9, and a transmission belt 11 rotatably disposed in the clutch frame 10. Furthermore, the transmission belt 11 is driven to rotate cyclically by a drive motor 12, and the extension movement of the telescopic cylinders 9 causes the transmission belt 11 to press against the roller 6 to achieve friction transmission.

[0026] As a preferred embodiment, the telescopic cylinder 9 is a pneumatic cylinder, and the cylinder is connected to the air source generator 13. The raising and lowering of the cylinder's telescopic rod can be controlled by adjusting the regulating valve connected between the air source generator 13 and the cylinder. Since gas has a certain compressibility, the cylinder also has a certain compressibility, which reduces damage during transmission, preventing damage when the roller 6 and the transmission belt 11 become jammed. The outer surface of the transmission belt 11 is textured, and the corresponding transmission contact parts of the roller 6 are knurled to increase transmission friction and ensure the stability of the egg-turning operation.

[0027] To fully utilize light and provide uniform light distribution, a reflector 14 is positioned directly below the lighting device 7. The reflector 14 is a convex curved panel that evenly reflects light onto the egg surface, improving the accuracy of crack detection. To further optimize the light-gathering effect, a light shield 15 is positioned above the frame 1. The light shield 15 has openings on both sides to allow workers to observe the cracks in the duck eggs while preventing external light from interfering with the detection process. A maintenance through-hole 16 is formed on the side of the frame 1. This elongated through-hole 16 is used for observing or disassembling the lighting device 7, facilitating equipment maintenance and repair.

[0028] Furthermore, the connector 2 is a concave steel. One end of the concave steel is fixedly connected to the frame 1 by bolts, and the other end is fixedly connected to the base frame 3 by bolts, ensuring the stability and detachability of the device.

[0029] When using the egg-turning device for inspecting sea duck eggs with cracks, the worker places the sea duck eggs to be inspected at the front end of the chain. The chain continuously feeds and arranges the eggs between the rollers 6. The rotating chain 4 drives the rollers 6 to rotate synchronously, slowly turning the eggs. When the eggs reach their designated station, the chain 4 stops, and the lighting device 7 is turned on to illuminate the eggs. The reflector 14 evenly reflects the light onto the egg surface. Workers observe the eggshells for cracks to confirm the quality and remove any defective eggs. During manual observation, the eggshell needs to be rotated once to observe the entire egg. When the egg needs to be turned, the telescopic cylinder 9 extends, and the transmission belt 11 presses against the rollers 6, turning the egg through friction transmission. This allows workers to fully observe the crack situation of the entire egg. After turning, the telescopic cylinder 9 retracts, the transmission belt 11 separates from the rollers 6, and the egg continues to move with the rotating chain 4 for the next round of feeding and inspection.

[0030] When inspection or maintenance is required, staff can observe the condition of the lighting device 7 through the maintenance through-hole 16 or disassemble and replace the lighting device 7 as needed to ensure the normal operation of the equipment.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
