Description

Technical Field

[0001] This application relates to the technical field of soft-boiled egg production lines, and in particular to a soft-boiled egg cooking swing device. Background Technology

[0002] In the industrial production of soft-boiled eggs, after washing, the eggs are typically put into a boiling water tank through a production line for cooking. The cooking time in the boiling water tank is controlled by the conveyor speed of the conveyor equipment to complete the cooking process of soft-boiled eggs.

[0003] Because eggs are conveyed in the boiling water tank using a conveyor belt, although the boiling water slightly agitates the eggs, some eggs still end up with yolks that are not centered after cooking. This not only affects the quality of the eggs but also reduces the amount of runny yolk. Therefore, ideally, the eggs should be kept rolling during the soft-boiled egg cooking process to ensure the yolk remains centered, thus improving the quality of the soft-boiled eggs. Summary of the Invention

[0004] In order to improve the defect that the yolk of a soft-boiled egg is not centered during the cooking process, this application provides a soft-boiled egg cooking swing device.

[0005] The oscillating device for cooking soft-boiled eggs provided in this application adopts the following technical solution: A device for cooking soft-boiled eggs, comprising: Hot water tank, with an opening at the top, and an electric heating device installed inside; The swing frame is rotatably connected inside the hot water tank, and the rotating shaft is driven to swing by a drive device installed outside the hot water tank; The conveying device is a chain plate conveyor belt, which is installed inside the hot water tank and is driven to rotate by a motor installed on the hot water tank through a rotating shaft; The receiving frame has a connecting plate at the bottom, which is rotatably connected to the chain plate of the conveyor device. The axis of rotation is parallel to the axis of rotation of the swing frame. The chain plate of the conveyor device has spring clamps installed on both sides of the connecting plate to keep the receiving frame parallel to the corresponding chain plate. Side panels are installed on both sides of the receiving frame; The swing frame's rotation axis is located below the conveying device. During the rotation of the swing frame, it will abut against the end of the receiving frame and drive the receiving frame to rotate.

[0006] Optionally, the swing frame and the conveying device are both inclined upwards from the front end to the rear end of the hot water tank. The hot water tank is fed from the front end and discharged from the rear end. Multiple receiving frames are grouped together. In the receiving frame group above the conveying device, the receiving frame closest to the rear end of the hot water tank is equipped with a front baffle, and the receiving frame closest to the front end of the hot water tank is equipped with a rear baffle.

[0007] Optionally, the receiving frame is above the water surface of the hot water tank when it moves to the highest point. The hot water tank is equipped with a downward-sloping discharge frame plate at the end. As the receiving frame moves downward, it discharges the eggs into the discharge frame plate.

[0008] Optionally, both the front and rear baffles are provided with multiple clearance holes, and multiple receiving rods are fixed on the top of the discharge frame plate. If the distance between the receiving rods is insufficient for the eggs to pass through, the receiving rods will pass through the clearance holes.

[0009] Optionally, the swing frame is positioned at the front and rear ends of the conveying device to avoid contact with the receiving frame.

[0010] Optionally, in a set of multiple receiving frames, the two ends of the receiving frame where the rear baffle is located are extended to form contact parts, and the swing frame can only abut against the contact parts of the receiving frame. In a set of multiple receiving frames, except for the receiving frame where the rear baffle is located, the other receiving frames are all fixed with lower push blocks at both ends of the side wall near the front baffle. In a set of multiple receiving frames, except for the receiving frame where the front baffle is located, the other receiving frames have lower guide grooves on both ends of the side wall near the rear baffle. The lower guide block can extend into the lower guide groove through the top of the lower guide groove.

[0011] Optionally, a feeding frame is provided at the front end of the hot water tank. The bottom of the feeding frame extends into the water body of the hot water tank and is located above the receiving frame. Multiple intercepting bars are fixed at the bottom of the feeding frame near the front end of the hot water tank. The distance between the intercepting bars is not enough for an egg to pass through. The intercepting bars can pass through the clearance hole. A passage groove is opened at the bottom of the feeding frame near the rear end of the hot water tank for the front baffle and the rear baffle to pass through.

[0012] Optionally, push plates are provided on both sides of the swing frame.

[0013] Optionally, the push plate is tilted so that it faces the rotation axis of the swing frame and has multiple water-permeable holes.

[0014] Optionally, the push plate is provided with multiple pressure relief holes, and a pressure relief valve is rotatably connected to each pressure relief hole; When the pusher plate moves toward the axis of rotation of the swing frame, the pressure relief valve will close the pressure relief hole under the thrust of the water flow. As the pusher plate moves away from the axis of rotation of the swing frame, the pressure-reducing valve opens the pressure-reducing hole under the thrust of the water flow. In summary, this application includes at least one of the following beneficial technical effects: 1. After the eggs are placed in the hot water tank, they fall into the receiving frame and are cooked in the boiling water. During the cooking process, the swinging frame swings and rotates, constantly pressing on both sides of the receiving frame, causing the receiving frame to rotate repeatedly from left to right, causing the eggs on the receiving frame to roll continuously. This method ensures that the yolk of the soft-boiled egg is in the center. 2. The receiving frame is rotatably connected to the chain plate of the conveying device via a connecting plate, enabling the receiving frame to be transported together with the chain plate of the conveying device. It can also rotate repeatedly with the rotation of the swing frame to achieve rolling during the egg cooking and conveying process. Multiple receiving frames are grouped together and form a frame structure together with side plates, front baffles and rear baffles to restrict the movement space of the eggs. In conjunction with the setting of the discharge frame plate, the eggs are automatically cooked, tumbled and conveyed to the next equipment to cooperate with the subsequent production line for shelling processing. The inclined setting of the conveying device can increase the effective water depth of the egg drop part to improve the protection of the eggs. 3. Multiple receiving frames in a group will rotate and reset together through the contact between the lower push block and the lower push groove, effectively reducing the probability of eggs leaking out of the space between the receiving frames. The extended setting of the receiving frame where the rear baffle is located, together with the widening setting of the front and rear ends of the swing frame, can ensure that multiple receiving frames in a group move to the top of the conveying device before rotating with the swing frame, improving the rationality of the structural design and reducing the probability of eggs breaking. The swing frame not only rotates and presses against the receiving frame to make the egg roll repeatedly, but also pushes the water in the hot water tank through the pusher plate to move the water. The water permeable holes reduce the resistance of the pusher plate to improve its protection, and the pressure relief valve pushes more water from the part near the edge of the hot water tank to the other side, reducing the resistance of the other pusher plate and helping to improve the rolling effect of the egg, so as to ensure that the yolk of the soft-boiled egg is centered.

[0017] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0018] This application discloses a swinging device for cooking soft-boiled eggs.

[0019] refer to Figure 1 and Figure 2 The soft-boiled egg cooking device includes a hot water tank 1, a swing frame 2, and a conveying device 3. The hot water tank 1 has an opening at the top and is rectangular in shape. The end where the eggs are fed is the front end of the hot water tank 1; the end where the eggs are removed is the rear end of the hot water tank 1. An electric heating device is installed inside the hot water tank 1 to heat the water inside to boiling.

[0020] The swing frame 2 is rotatably connected inside the hot water tank 1. Its rotation axis extends from the front end to the rear end of the hot water tank 1 and is inclined upwards, with the rotation axis located at its bottom. The rotation axis of the swing frame 2 is driven by a drive device installed outside the hot water tank 1 to swing left and right repeatedly. The drive device includes a servo motor and a reducer, both of which are mounted on the front outer wall of the hot water tank 1. The servo motor drives the swing frame 2 to rotate through the reducer.

[0021] The conveyor device 3 is a chain conveyor belt, installed inside the hot water tank 1, and inclined upwards from the front end to the rear end of the hot water tank 1. The conveyor device 3 is located inside the swing frame 2, and directly above the rotation axis of the swing frame 2. The rotation axis of the swing frame 2 is parallel to the conveying direction of the conveyor device 3.

[0022] The conveyor 3 has a chain plate with a receiving frame 4 that moves the eggs within the hot water tank 1. The swing frame 2 swings the receiving frame 4 to make the eggs roll. The swing frame 2 is equipped with a water-pushing component 7 that pushes the water during the swinging process.

[0023] Eggs are dropped into hot water tank 1 from the front end. A receiving frame 4 catches the eggs as they fall into the tank and, under the movement of a conveyor device 3, transports them to the rear end of the tank. The inclined design of the conveyor device 3 effectively increases the water depth at the point where the eggs fall, improving egg protection. The inclined design also helps to lift the eggs out of the tank. The swinging frame 2, through its contact with the receiving frame 4 during its swinging motion, causes the receiving frame 4 to rotate left and right, making the eggs on it roll and ensuring the yolk of the soft-boiled egg remains centered.

[0024] refer to Figure 3 , Figure 4 and Figure 5 A connecting plate 41 is fixedly installed at the bottom center of the receiving frame 4. The connecting plate 41 is rotatably connected to the center of the chain plate of the conveying device 3, so that the rotation axis of the connecting plate 41 is directly above the rotation axis of the swing frame 2. Spring clamps 31 are installed on both sides of the chain plate of the conveying device 3 at the connecting plate 41. The other end of the spring clamp 31 abuts against the connecting plate 41, keeping the connecting plate 41 in a vertical state. At this time, the receiving frame 4 is parallel to the corresponding chain plate.

[0025] Combined Figure 6 and Figure 7 The receiving frame 4 includes a frame body and multiple receiving rods. The receiving rods are parallel to each other and fixed to the inner wall of the frame. The distance between the receiving rods is insufficient for an egg to pass through, forming a permeable structure. Side plates 42 are fixed to both ends of the upper surface of the receiving frame 4 to intercept the egg during the swinging process. Multiple receiving frames 4 are grouped together; in this embodiment, four are grouped together. In the group of receiving frames 4 above the conveying device 3, the receiving frame 4 closest to the rear end of the hot water tank 1 is provided with a front baffle 43, and the receiving frame 4 closest to the front end of the hot water tank 1 is provided with a rear baffle 44. The height of the front baffle 43 and the rear baffle 44 is the same as that of the side plates 42.

[0026] Both the front baffle 43 and the rear baffle 44 have multiple clearance holes 431 on their tops, with the clearance holes 431 on the front baffle 43 and the rear baffle 44 positioned opposite each other. A downwardly inclined discharge frame plate 5 is mounted at the end of the hot water tank 1. When the receiving frame 4 is at its highest point, it is above the water surface in the hot water tank 1 and above the discharge frame plate 5. Multiple receiving rods 51 are fixed to the top of the discharge frame plate 5. Since the distance between the receiving rods 51 is insufficient for an egg to pass through, the receiving rods 51 will pass through the clearance holes 431. As the receiving frame 4 rotates downwards with the conveyor device 3, it discharges the eggs into the discharge frame plate 5, and then conveys them to the shelling equipment through the discharge frame plate 5.

[0027] A feeding frame 6 is provided at the front end of the hot water tank 1. The bottom of the feeding frame 6 extends into the water body of the hot water tank 1 and is located above the receiving frame 4. Multiple intercepting rods 61 are fixed to the bottom of the feeding frame 6 near the front end of the hot water tank 1. The distance between the intercepting rods 61 is insufficient for an egg to pass through, and the intercepting rods 61 can pass through the clearance hole 431. A passage groove 62 is provided at the bottom of the feeding frame 6 near the rear end of the hot water tank 1, allowing the front baffle 43 and the rear baffle 44 to pass through.

[0028] The swing frame 2 is positioned to avoid contact with the front and rear ends of the conveying device 3, and will not abut against the receiving frames 4 at the front and rear ends of the conveying device 3. The part where the unloading frame 6 is located is directly opposite the widened part at the front end of the swing frame 2. Among the multiple receiving frames 4 in a group, the two ends of the receiving frame 4 where the rear baffle 44 is located are extended to form contact parts 47. The swing frame 2 can only abut against the contact parts 47 of the receiving frame 4. Among the multiple receiving frames 4 in a group, except for the receiving frame 4 where the rear baffle 44 is located, the two ends of the side wall of the other receiving frames 4 near the front baffle 43 are all fixed with lower push blocks 45. Among the multiple receiving frames 4 in a group, except for the receiving frame 4 where the front baffle 43 is located, the two ends of the side wall of the other receiving frames 4 near the rear baffle 44 are all provided with lower push grooves 46, and the lower push blocks 45 can extend into the lower push grooves 46 through the top of the lower push grooves 46.

[0029] Multiple receiving frames 4 within a group intercept the eggs through a frame structure formed by side plates 42, front baffles 43, and rear baffles 44, causing the eggs to roll within the enclosed area and move with the receiving frames 4. As the receiving frames 4 move out of the water and begin to rotate downwards, they discharge the eggs into the discharge frame plate 5, thus automatically discharging the soft-boiled eggs from the hot water tank 1. The clearance hole 431 and the receiving rod 51 allow the front baffles 43 and rear baffles 44 to pass stably through the discharge frame 6, improving the efficiency of eggs being discharged onto the discharge frame plate 5. The discharge frame 6 ensures that the eggs fall stably into the corresponding receiving frames 4, and the intercepting rod 61 does not obstruct the passage of the front baffles and rear baffles 44, preventing the eggs from falling outside the receiving frames 4.

[0030] The lower push block 45 and lower push groove 46 allow multiple receiving frames 4 within a group to rotate together with the receiving frame 4 containing the rear baffle 44. Furthermore, the contact part 47, combined with the widened portion of the swing frame 2, ensures that the receiving frames 4 only rotate after the contact part 47 comes into contact with the swing frame 2. This reduces the probability of eggs leaking out if some receiving frames 4 contact the swing frame 2 first, creating gaps between the receiving frames 4. This improves egg protection and the stability of egg transport. The position of the swing frame 2 prevents the receiving frames 4 under the feeding frame 6 and those discharging eggs from rotating, further enhancing egg protection and reducing leakage.

[0031] refer to Figure 6 and Figure 8 The water-pushing assembly 7 includes a water-pushing plate 71 and a pressure-reducing gate 72. The water-pushing plate 71 is positioned on both sides of the swing frame 2. When the swing frame 2 is horizontal, the space between the water-pushing plate 71 and the receiving frame 4 and the chain plate of the conveying device 3 is opposite. The water-pushing plate 71 is inclined, facing the rotation axis of the swing frame 2. Multiple water-permeable holes 711 are formed on the surface of the water-pushing plate 71 to reduce water resistance. Multiple pressure-reducing holes 712 are spaced apart on the water-pushing plate 71, and the pressure-reducing gate 72 is rotatably connected to the pressure-reducing holes 712. When the water-pushing plate 71 moves towards the rotation axis of the swing frame 2, the pressure-reducing gate 72 closes the pressure-reducing holes 712 under the thrust of the water flow. When the water-pushing plate 71 moves away from the rotation axis of the swing frame 2, the pressure-reducing gate 72 opens the pressure-reducing holes 712 under the thrust of the water flow.

[0032] The pusher plate 71 pushes the water during the rotation of the swing frame 2, causing the water to flow intermittently to both sides, thereby assisting in pushing the egg on the receiving frame 4 and improving the rolling effect of the egg. The pressure relief gate 72 opens and closes during the movement of the swing frame 2, allowing the pusher plate 71 to push the water from one side to the other with less resistance. Because a pusher plate 71 with the pressure relief hole 712 open would push the water directly against the side wall of the hot water tank 1, resulting in poor egg rolling, the pressure relief hole 712 is opened through the pressure relief gate 72 to reduce the rotational resistance of the swing frame 2.

[0033] The implementation principle of this embodiment is as follows: Eggs enter the hot water tank 1 through the feeding frame 6 and fall onto the receiving frame 4, moving with it. During this movement, the swing frame 2 rotates and contacts the contact part 47, causing multiple receiving frames 4 in the corresponding group to rotate, thus rolling the eggs on the receiving frames 4 to one side. Simultaneously, the swing frame 2 also pushes the water to one side through the pusher plate 71, further assisting the eggs in rolling, thereby improving the rolling effect on the receiving frames 4 and ensuring the yolk of the cooked soft-boiled egg is centered, improving product quality.

[0034] When the swing frame 2 separates from the contact part 47, the receiving frame 4 will reset under the action of the spring clamp 31, and when the swing frame 2 abuts against the contact part 47 on the other side, it will drive the receiving frame 4 to rotate to the other side. The eggs will be cooked until soft-boiled in the hot water tank 1, and then removed from the water in the hot water tank 1 by the conveying of the receiving frame 4, and discharged onto the discharge frame plate 5 to enter the peeling equipment for the next step.

[0035] In this embodiment, only eggs are used for illustration. If other types of eggs are to be processed into soft-boiled eggs, the dimensions of the clearance hole 431, the front baffle 43, the rear baffle 44 and the side plate 42, as well as the gaps of the intercepting rod 61 and the receiving rod 51, need to be adjusted.

[0036] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
