[0039] Example 1:

[0040] Please refer to Figure 1-9 This embodiment provides an automatic egg-breaking and opening structure for an egg-frying machine, including a frame 10, and an egg-breaking rack 20, a movable seat 30, a blade assembly 40, and a drive assembly 50 mounted on the frame 10.

[0041] In this embodiment, the frame 10 mainly serves as a support and connection, through which the egg breaking and opening structure is installed inside the automatic egg frying machine; the frame 10 includes a base plate 11 and a side plate 12.

[0042] The egg-breaking rack 20 has an egg-breaking station 21, which can accommodate one egg.

[0043] The movable seat 30 is slidably connected to the base plate 11. The movable seat 30 has a first position and a second position on the base plate 11. The first position is when the movable seat 30 is moved away from the egg-breaking station 21, and the second position is when the movable seat 30 is moved closer to the egg-breaking station 21. A lever 31 is provided on one side of the movable seat 30. By pushing and pulling the lever 31, the movable seat 30 can be moved back and forth between the first position and the second position.

[0044] The cutting tool assembly 40 is connected to the movable seat 30. The cutting tool assembly 40 includes a slider 41, a lever 42, a first blade 43, and a second blade 44. The lever 42 is connected to the first blade 43 and the second blade 44 via the slider 41. The slider 41 is slidably connected to the movable seat 30. The slider 41 has a third position and a fourth position. When the slider 41 is translated to the third position, the first blade 43 and the second blade 44 are brought together. When the slider 41 is translated to the fourth position, the first blade 43 and the second blade 44 are opened. By pushing and pulling the lever 42, the slider 41 can be driven to move back and forth between the third position and the fourth position, controlling the first blade 43 and the second blade 44 to bring together or open.

[0045] The drive assembly 50 is disposed on one side of the movable seat 30. The drive assembly 50 includes a dial drive 51 and a dial body 52. ​​The dial body 52 is connected to the output end of the dial drive 51.

[0046] Based on the above structure, during use, the dial drive 51 provides power to drive the dial body 52 to rotate. The dial body 52, in conjunction with the lever 31, drives the movable seat 30 to switch between a first and second position, allowing the blade assembly 40 to extend into the egg-breaking station 21 to break the egg. The dial body 52, in conjunction with the lever 42, drives the slider 41 to switch between a third and fourth position, causing the first blade 43 and the second blade 44 to converge or diverge, opening the eggshell in the egg-breaking station 21 to both sides, allowing the egg liquid to fall smoothly into the preset position. In this embodiment, the automatic egg-breaking and opening structure of the egg-frying machine can be controlled sequentially by a single dial drive 51, making the actions between breaking and opening the egg more fluid and stable, and saving energy.

[0047] Specifically, the dial body 52 has a first angle, a second angle, a third angle, and a fourth angle; when the dial body 52 rotates to the first angle, the dial body 52 separates from the lever 31; when the dial body 52 rotates to the second angle, the dial body 52 contacts the lever 31; when the dial body 52 rotates to the third angle, the dial body 52 contacts the dial plate 42; and when the dial body 52 rotates to the fourth angle, the dial body 52 separates from the dial plate 42.

[0048] A first elastic element 32 is provided between the movable seat 30 and the side plate 12. The first elastic element 32 provides an elastic force to drive the movable seat 30 to move from a first position to a second position.

[0049] A second elastic element 45 is provided between the lever 42 and the movable seat 30. The second elastic element 45 provides an elastic force to drive the movable seat 30 to reset from the fourth position to the third position.

[0050] In the initial state, the dial drive 51 drives the dial body 52 to rotate to near the first angle. At this time, the movable seat 30 is moved to the first position, and the first blade 43 and the second blade 44 retract from the egg-breaking station 21. At this time, the slider 41 slides to the third position under the action of the second elastic member 45, and the first blade 43 and the second blade 44 come together. After being fed and corrected by the preceding components, the egg is sent to the egg-breaking station 21 and fixed by the front baffle and the rear pressure plate set in front of and behind the egg-breaking station 21, and is ready to be placed in the egg-breaking station 21. The dial body 52 rotates and separates from the lever 31. The movable seat 30 springs to the second position under the elastic force of the first elastic element 32, driving the gathered first blade 43 and second blade 44 into the egg-breaking station 21 to break the egg ready at the egg-breaking station 21. The dial body 52 continues to rotate to the third angle, and the dial body 52 contacts the lever 42. The lever 42 drives the slider 41 to move horizontally on the movable seat 30, so that the slider 41 moves from the third position to the fourth position. The first blade 43 and second blade 44 gradually open from the initial gathered state, pushing the eggshell of the egg at the egg-breaking station 21 to both sides. When the dial body 52 continues to rotate to the fourth angle, the dial body 52 separates from the lever 42, and the slider 41 returns to the third position under the action of elastic force, and the first blade 43 and second blade 44 gather together. The dial body 52 continues to rotate to the second angle, contacting the lever 31 and causing the lever 31 to translate. This overcomes the elastic force of the first elastic element 32, pushing the movable seat 30 to the first position. The first blade 43 and the second blade 44 retract from the egg-breaking station 21, preparing for the next egg-breaking and opening task. In this embodiment, the egg ready at the egg-breaking station 21 is quickly broken open by the instantaneous force of the first elastic element 32. The fast cutting speed saves power and reduces the generation of eggshell fragments.

[0051] Furthermore, a linear guide rail is provided on the base plate 11, and a guide block is connected to the bottom of the movable seat 30. The movable seat 30 is slidably connected to the base plate 11 by the cooperation of the guide block and the linear guide rail. A limiting part is formed at the bottom of the movable seat 30. When the movable seat 30 slides to the first position, the limiting part abuts against the end of the linear guide rail, restricting the further displacement of the movable seat 30.

[0052] A sliding groove is formed on the movable seat 30, and the slider 41 is disposed in the sliding groove; a plurality of limiting posts 33 are provided on the movable seat 30, and a channel is formed between the plurality of limiting posts 33 to allow the dial plate 42 to pass through, and the dial plate 42 is guided through the channel.

[0053] The tool assembly 40 in this embodiment further includes a first tool holder plate 46 and a second tool holder plate 47; one end of the first tool holder plate 46 is connected to the first blade 43, and the other end forms a first hinge shaft, which is connected to the movable seat 30; one end of the second tool holder plate 47 is connected to the second blade 44, and the other end forms a second hinge shaft, which is connected to the movable seat 30; thereby, both the first tool holder plate 46 and the second tool holder plate 47 can rotate relative to the movable seat 30, causing the first blade 43 and the second blade 44 to converge or diverge.

[0054] The rotation of the first blade holder plate 46 and the second blade holder plate 47 can be driven by a linkage mechanism. However, there is sliding friction at the hinge of this linkage mechanism, and the inertial force of the linkage will cause additional energy loss, resulting in poor transmission efficiency and easy jamming, which leads to poor stability in the egg-opening process. This embodiment has optimized this aspect. Specifically, the first hinge shaft and the second hinge shaft are both formed with a number of first meshing teeth in the circumferential direction.

[0055] The slider 41 is connected to a toothed plate 48, and the toothed plate 48 has second meshing teeth formed on opposite sides; the first meshing teeth are adapted to the second meshing teeth.

[0056] In use, the slider 41 drives the toothed plate 48 to translate. The second meshing teeth on both sides of the toothed plate 48 respectively engage with the first meshing teeth on the first cutter holder plate 46 and the second cutter holder plate 47, causing the first cutter holder plate 46 and the second cutter holder plate 47 to rotate synchronously, so that the first blade 43 and the second blade 44 come together or open. The structure is compact and there is no slippage, ensuring the synchronization of the first blade 43 and the second blade 44.

[0057] In some other embodiments, a positioning sensor 60 is also included, which is used to detect whether the movable seat 30 is close to the second position. A main control board is also included, which is electrically connected to the dial drive 51 and signal-connected to the positioning sensor 60.

[0058] The main control board controls the rotation angle of the dial wheel body 52 by controlling the dial wheel drive 51. When the main control board receives the egg-breaking and egg-opening task, the position sensor 60 is used to detect whether the movable seat 30 is close to the first position. If the movable seat 30 is in position, the dial wheel drive 51 is activated to make the dial wheel body 52 sequentially pass through the first angle, the third angle, the fourth angle, and the second angle to perform the egg-breaking and egg-opening steps. If the movable seat 30 is not in position, the dial wheel drive 51 is activated to make the dial wheel body 52 rotate from the second angle to a position close to the first angle, and the movable seat 30 is moved to the first position to prepare for the egg-breaking and egg-opening task, thus realizing intelligent control.

[0059] The egg in this embodiment is only for the purpose of describing this application and simplifying the description, and should not be construed as a limitation of this application. After adaptive adjustments, the egg breaking and opening structure of this embodiment can also be adapted to the use of duck eggs, goose eggs, quail eggs, wild bird eggs or other special poultry eggs; this will be understood by those skilled in the art.

[0060] Although certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0061] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
