Description

Technical Field

[0001] This utility model belongs to the field of egg-frying machine technology, specifically relating to an automatic egg-flipping mechanism and an automatic egg-frying machine. Background Technology

[0002] Flipping an egg during cooking is a common operation, traditionally done manually with a spatula. To improve cooking efficiency or automate the process, various egg-flipping mechanisms have been proposed in existing technologies.

[0003] For example, CN202211641165.8 discloses an automatic egg-flipping mechanism, and CN202310011226.0 discloses a cooking device whose core structure includes: a fixed plate, an upper and lower pan (both equipped with egg outlets, with the upper pan's outlet located above the lower pan), an upper spatula and a push plate respectively disposed in the upper and lower pans, and a drive system. Specifically, a drive component (drive cylinder) disposed on one side of the fixed plate links the upper spatula and push plate through a sliding block to realize the pushing and flipping operation of the fried egg.

[0004] In actual operation, the aforementioned patent exhibits a significant timing control issue: after the first side of the egg is cooked in the pan and then flipped over to be placed back in the pan, the second side of the egg begins to cook. At this point, the pan is refilled with oil and egg mixture to begin a new round of cooking. However, due to the rigid linkage design of the spatula and push plate, the cooking time in the second side inevitably exceeds that in the first side, making it difficult to ensure consistent cooking on both sides. Although the patent specification mentions the possibility of using two drive components to drive the spatula and push plate respectively, this improvement would significantly increase equipment costs, and the introduction of multiple electrical components would correspondingly increase the risk of system failure, resulting in significant drawbacks in both practicality and economy. Utility Model Content

[0005] To address the technical problems existing in the prior art, the first aspect of this utility model is to provide an automatic egg-flipping and frying mechanism. Secondly, based on the same inventive concept, this utility model also provides an automatic egg-frying machine based on the aforementioned automatic egg-flipping and frying mechanism.

[0006] In this embodiment of the utility model, the automatic egg-flipping mechanism includes a mounting frame with an upper pan and a lower pan on it. Both the upper and lower pans have egg outlets, with the upper pan's outlet located above the lower pan. The upper pan and mounting frame are rotatably connected via an upper pan pivot, while the lower pan is slidably connected to the mounting frame. The mounting frame also includes a push plate located in the lower pan and a drive mechanism for moving the upper and lower pans. The drive mechanism includes a turntable rotatably connected to the mounting frame, a drive component for rotating the turntable, and a first transmission mechanism and a second transmission mechanism connected to the turntable. The turntable is connected to the upper pan via the first transmission mechanism. Driven by the drive component, the turntable rotates. Under the transmission action of the first transmission mechanism, the upper pan can tilt towards the lower pan, causing the eggs to fall and flip into the lower pan. The turntable is connected to the lower pan via the second transmission mechanism. Driven by the drive component, the turntable rotates. Under the transmission action of the second transmission mechanism, the lower pan moves relative to the push plate, which pushes out the eggs.

[0007] The automatic egg-frying machine of this utility model includes an egg container, an egg conveying device for conveying eggs from the egg container to an egg-breaking station, an egg-breaking mechanism for breaking the shells of the eggs at the egg-breaking station, a cooking mechanism for frying the eggs on both sides located below the egg-breaking station, and an oil supply mechanism for adding edible oil to the cooking mechanism. The cooking mechanism is the automatic egg-flipping and frying mechanism provided in this application.

[0008] Compared with the prior art, the beneficial effects of the superior technical solution of this utility model include:

[0009] 1. Single-drive time-sharing control: Only one drive unit is needed to complete the two actions of tilting the upper pot to dispense eggs and pushing the lower pot to dispense eggs in sequence, which significantly reduces manufacturing costs and system complexity.

[0010] 2. Precise timing adjustment: By controlling the start and stop of the drive components, the rotation angle and pause time of the turntable can be precisely adjusted, thereby independently controlling the timing of putting the eggs into and taking them out of the pan, ensuring that the cooking time for both sides of the eggs is adjustable.

[0011] 3. High structural reliability: Compared with multiple electrical components, mechanical transmission mechanisms reduce the number of failure points and improve long-term stability.

[0012] 4. This utility model ensures the consistency of fried egg quality while taking into account production efficiency and equipment economy, and is suitable for the promotion and application of automated cooking equipment. Attached Figure Description

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] This embodiment provides an automatic egg-flipping mechanism, such as... Figures 1-4 As shown, the egg-frying mechanism includes a mounting rack 41, on which an upper pan 42 and a lower pan 43 are provided. The upper pan 42 and the lower pan 43 are provided with egg outlets. The egg outlet of the upper pan 42 is located above the lower pan 43. The inner surfaces of the upper pan 42 and the lower pan 43 are provided with an anti-stick layer. The structure of the upper pan 42 and the lower pan 43 can adopt existing technology, and this utility model does not make any improvements.

[0021] In this invention, the upper pot 42 is located to the upper left of the lower pot 43, with a height difference of 80 cm between them. The upper pot 42 is rotatably connected to the mounting frame 41 via an upper pot pivot 421. Preferably, an upper pot pivot 421 is fixed to each side of the upper pot 42 in the width direction and rotatably connected to the mounting frame 41, making the movement of the upper pot 42 more stable. The lower pot 43 is slidably connected to the mounting frame 41 longitudinally (in the length direction of the upper pot 42 and the lower pot 43). The mounting frame 41 is also equipped with a push plate 44 located on the left side of the lower pot 43 and extending along the width direction of the lower pot 43, as well as a drive mechanism 45 for driving the movement of the upper pot 42 and the lower pot 43. The drive mechanism 45 includes a turntable 451 rotatably connected to the outer wall of the mounting frame 41, a drive member 452 for driving the turntable 451 to rotate, and a first transmission mechanism 453 and a second transmission mechanism 454 connected to the turntable 451.

[0022] The turntable 451 is connected to the upper pot 42 via a first transmission mechanism 453. Driven by a driving component 452, the turntable 451 rotates. Under the transmission of the first transmission mechanism 453, the upper pot 42 can tilt towards the lower pot 43 (e.g., at an angle of 38°-42°) to allow the eggs to fall and flip into the lower pot 43. The specific method of egg falling and flipping is existing technology, and its process and principle are not detailed here. The turntable 451 is connected to the lower pot 43 via a second transmission mechanism 454. Driven by a driving component 452, the turntable 451 rotates. Under the transmission of the second transmission mechanism 454, the lower pot 43 can move relative to the push plate 44, which pushes the eggs out of the lower pot 43.

[0023] When using this automatic egg-flipping mechanism to fry eggs, first pour cooking oil into the upper pan 42, such as... Figure 3 As shown, initially, the lower pan 43 is empty. Then, the egg mixture is cracked into the upper pan 42. After one side of the egg is cooked in the upper pan 42, the turntable 451 is rotated via the drive component 452. Figure 4 As shown, under the transmission action of the first transmission mechanism 453, the upper pan 42 tilts towards the lower pan 43 to allow the eggs in the upper pan 42 to fall and flip into the lower pan 43, where the other side of the eggs is fried. After the eggs are poured from the upper pan 42 into the lower pan 43, as... Figure 1 As shown, the turntable 451 rotates to return the tilted upper pan 42 to its original position, after which the next egg can be fried in the upper pan 42. Figure 2 As shown, after the eggs are cooked on the second side in the pan 43, the turntable 451 is rotated by the drive component 452. Under the transmission action of the second transmission mechanism 454, the pan 43 moves relative to the push plate 44, and the push plate 44 pushes the eggs out of the pan 43. The pushed eggs fall into the food plate below the pan 43. Figure 3As shown, the turntable 451 then rotates, causing the lower pan 43 to move in the opposite direction to the push plate 44 and reset, waiting for the upper pan 42 to transfer the next egg, which has been fried on one side, into the lower pan 43.

[0024] The egg-frying mechanism adopts a design scheme with a single drive component 452 and timing control. It mainly consists of the drive component 452, a turntable 451, and independent first and second transmission mechanisms 453 and 454. Its working principle is as follows: when the drive component 452 drives the turntable 451 to rotate, the first transmission mechanism 453 controls the upper pan 42 to tilt towards the lower pan 43, realizing the automatic transfer of the fried egg; at the same time, the turntable 451 drives the lower pan 43 to move relative to the push plate 44 through the second transmission mechanism 454, completing the final push of the fried egg.

[0025] Combination Figure 5 As shown, in this utility model, the driving component 452 is a rotary motor. The output shaft of the rotary motor extends along the width direction of the upper pot 42. The output shaft of the rotary motor is coaxially fixed to a transmission shaft 4521. The transmission shaft 4521 passes through the front side wall of the mounting bracket 41 and is coaxially fixed to the turntable 451.

[0026] like Figure 1 As shown, in one embodiment of this utility model, the first transmission mechanism 453 is a cam mechanism. The first transmission mechanism 453 includes a protrusion 4531 eccentrically fixed to the turntable 451 (for example, the protrusion 4531 is fixed to the edge of the turntable 451), and a stop block 4532 fixed to the upper pot 42. By rotating the turntable 451, the rotation of the turntable 451 drives the protrusion 4531 to rotate. The protrusion 4531 can intermittently act on the stop block 4532 to lift the stop block 4532, so that the upper pot 42 rotates around the upper pot rotating shaft 421 and tilts towards the lower pot 43. Specifically, the abutment block 4532 is a strip-shaped block extending along the length of the upper pot 42. One end of the abutment block 4532 is fixedly connected to the upper pot rotating shaft 421. For example, the abutment block 4532 is set on the front side outside the mounting frame 41. The front end of the upper pot rotating shaft 421 passes through the mounting frame 41 and is fixedly connected to the right end of the abutment block 4532. The turntable 451 and the protrusion 4531 are also set on the front side outside the mounting frame 41, and the rotation center of the turntable 451 is located to the lower left of the abutment block 4532.

[0027] Combination Figure 4 As shown, the counterclockwise rotation of turntable 451 drives the protrusion 4531 to rotate, causing the protrusion 4531 and the abutment 4532 to move away from the left end of the upper pot rotating shaft 421, lifting the left end of the abutment 4532. This causes the left end of the abutment 4532 to rotate clockwise around the upper pot rotating shaft 421, and the abutment 4532 to tilt downwards from left to right. Since the upper pot 42 is fixedly connected to the abutment 4532, the upper pot 42 tilts towards the lower pot 43 as the abutment 4532 rotates clockwise around the upper pot rotating shaft 421. Figure 1As shown, after the protrusion 4531 leaves the abutment 4532, the tilted upper pot 42 returns to a horizontal state. The rotation of the turntable 451 drives the protrusion 4531 to rotate. When the protrusion 4531 contacts the left end of the abutment 4532, it can lift the left end of the abutment 4532, causing the upper pot 42 to tilt towards the lower pot 43, thus realizing the intermittent tilting action of the upper pot 42.

[0028] like Figure 1 and Figure 5 As shown, in another preferred embodiment, the left end of the abutment block 4532, away from the upper pot rotating shaft 421, is rotatably connected to a cylindrical abutment post 4533 via a pin 4534. The protrusion 4531 rolls against the abutment post 4533 to lift the left end of the abutment block 4532. This rotating abutment post 4533 structure can effectively reduce frictional resistance and improve energy efficiency.

[0029] Combination Figure 5 As shown, in another preferred embodiment, the left end of the abutment 4532 on the protrusion 4531, away from the upper pot rotating shaft 421, is elastically connected to the mounting bracket 41 via a columnar spring 455. The columnar spring 455 is inclined from left to right and from bottom to top. The upper end of the columnar spring 455 is rotatably connected to the pin 4534 of the abutment 4532, and the lower end of the columnar spring 455 is fixedly connected to the outer wall of the mounting bracket 41. By setting the columnar spring 455, when the protrusion 4531 pushes up the left end of the abutment 4532 to tilt the upper pot 42 towards the lower pot 43, the columnar spring 455 is stretched. Under the tension and buffering effect of the columnar spring 455, the tilt angle of the upper pot 42 can be limited, so that the upper pot 42 tilts at a set angle. After the protrusion 4531 rotates counterclockwise away from the abutment 4532, the stretched columnar spring 455 returns to its deformation, so that the upper pot 42 returns to a horizontal state.

[0030] like Figure 5 As shown, in another preferred embodiment, the mounting bracket 41 has a limiting member 456 at the end of the upper pot 42 away from the lower pot 43 (the left end in the figure). The limiting member 456 is a limiting post that extends along the width direction of the upper pot 42 and is adapted to the shape of the bottom left side of the upper pot 42. Under the tension of the columnar spring 455 of the protrusion 4531, when the upper pot 42 is reset to a horizontal state, the left end of the upper pot 42 away from the lower pot 43 can abut against the limiting member 456 of the protrusion 4531 and be supported by the limiting member 456, so as to ensure the stability of the upper pot 42 in a horizontal state.

[0031] like Figure 1As shown, in this utility model, the second transmission mechanism 454 is a crank-slider 458 mechanism. The second transmission mechanism 454 includes a connecting rod 4541 eccentrically rotatably connected to the turntable 451 (the connecting rod 4541 is rotatably connected to the outer periphery of the cross section of the turntable 451), and a connecting plate 4542 fixedly connected to the lower pot 43 and capable of moving along the length direction of the lower pot 43. The end of the connecting rod 4541 away from the turntable 451 is rotatably connected to the connecting plate 4542. By rotating the turntable 451, the rotation of the turntable 451 causes the connecting plate 4542 to drive the lower pot 43 to reciprocate linearly along its length direction via the connecting rod 4541. When the protrusion 4531 is vertically upward, the left end of the connecting rod 4541 is rotatably connected to the lower right side of the turntable 451. At this time, the connecting rod 4541 tilts from left to right from top to bottom.

[0032] Specifically, when the second side of the egg is cooked in the lower pan 43, the turntable 451 rotates counterclockwise, causing the connecting rod 4541 to drive the connecting plate 4542 to move to the left. The lower pan 43 moves to the left along with the connecting plate 4542, and the push plate 44 pushes the egg in the lower pan 43 out of the egg outlet at the right end of the lower pan 43. As the turntable 451 continues to rotate counterclockwise, the lower pan 43 moves to the right and resets, and the upper pan 42 transfers the next egg with one side cooked to the lower pan 43.

[0033] like Figure 5 As shown, in another preferred embodiment, a slide rail 457 extending along the length of the lower pot 43 is fixedly connected to the outer wall of the mounting bracket 41. A slider 458 fixedly connected to the connecting plate 4542 is slidably connected to the slide rail 457. The slide rail 457 is rigidly connected to the connecting plate 4542 through the slider 458 to form a sliding pair, thereby improving the stability of the movement.

[0034] More preferably, a connecting plate 4542 is fixedly connected to each side of the lower pot 43 in the width direction, and moves along the length direction of the lower pot 43. The two connecting plates 4542 move synchronously along the length direction. A protrusion 4531 slide rail 457 fixedly connected to the mounting bracket 41 is provided on each side of the lower pot 43. A slider 458 fixedly connected to the corresponding connecting plate 4542 is mounted on the slide rail 457. This slide rail 457-slider 458 mechanism provides bidirectional guidance for the reciprocating linear motion of the connecting plate 4542 and the lower pot 43, significantly improving the stability of the motion.

[0035] This embodiment uses Figure 1 Taking the vertically upward position of the protrusion 4531 as the initial state, the process of the turntable 451 rotating counterclockwise one revolution is as follows:

[0036] 1) The second side is cooked: as shown Figure 1 and Figure 2As shown, when the eggs in the lower pan 43 are cooked on the second side, the turntable 451 rotates counterclockwise, driving the lower pan 43 to move to the left, and the push plate 44 pushes the eggs out.

[0037] 2) Reset the pot at 43°C: (e.g.) Figure 3 As shown, after the push plate 44 completes the push-out action, the turntable 451 continues to rotate, and the lower pot 43 moves to the right and resets to the empty pot state.

[0038] 3) Egg transfer: such as Figure 4 As shown, the turntable 451 rotates further, and the protrusion 4531 and the abutment 4532 work together to tilt the upper pot 42, transferring the next egg to the lower pot 43.

[0039] 4) Reset the pot at 42 degrees Celsius and cook simultaneously: (e.g.) Figure 1 As shown, the protrusion 4531 disengages from the abutment 4532 and returns to a vertically upward state, the upper pan 42 returns to a horizontal position, and the next egg is started to be fried. At the same time, the lower pan 43 is used to fry the second side of the previous egg.

[0040] 5) Cycle: Once the second side of the egg (43) is cooked, turntable (451) rotates counterclockwise once more and repeats the above process. Example 2

[0041] This embodiment provides an automatic egg-frying machine, including an egg container, an egg conveying device for transporting eggs from the egg container to an egg-breaking station, an egg-breaking mechanism for breaking the shells of the eggs at the egg-breaking station, a cooking mechanism for frying the eggs on both sides located below the egg-breaking station, and an oil supply mechanism for adding cooking oil to the cooking mechanism. The cooking mechanism is the automatic egg-flipping mechanism of Embodiment 1 of this application. The other components (including the egg container, egg conveying device, egg-breaking mechanism, and oil supply mechanism) can be implemented with reference to existing technologies (such as those disclosed in CN117338183A and CN116473439A) and are not innovative points of this utility model, and will not be described further here.
