[0002] In large catering places such as restaurants and canteens, it is difficult to meet the demand by manually cooking fried eggs due to the large flow of people. Therefore, some large catering places use fried egg machines to quickly cook fried eggs instead of manually. The fried egg machine is a complex device that integrates multiple modules such as egg conveying mechanism, egg shell breaking mechanism, automatic frying pan, etc. on one device. Each link is carried out continuously without manual operation, which greatly improves the efficiency of cooking fried eggs.

[0003] The existing egg shell breaking mechanism, when breaking the egg shell to separate the egg liquid from the egg shell, hits the egg shell with a blade. After the egg shell is knocked open, the egg liquid flows downward from the broken gap of the egg shell, thereby achieving the purpose of separating the egg liquid from the egg shell. Although the existing egg shell breaking mechanism can hit the egg shell with a blade to knock the egg shell open, the broken gap of the egg shell is small, resulting in a low rate of downward flow of the egg liquid, resulting in a long time required to separate the egg liquid from the egg shell, thereby affecting the efficiency of the egg frying machine.

[0030] like Figure 1 , 2 , 3, 4, and 5 show an eggshell breaking mechanism of the utility model, which includes a support plate 10, a bracket 20, a movable seat 30, a drive unit, a drive assembly, and two blades 50. The support plate is used to provide a mounting base for the entire mechanism. The bracket 20 is mounted on the support plate 10. A groove 21 is formed on the bracket 20 to prevent eggs from being cut. An opening 22 is formed on the side of the groove 21 facing the movable seat 30. The two blades 50 and the drive assembly are both mounted on the movable seat 30. The drive assembly is used to drive the two blades 50 to move simultaneously so that the two blades 50 can be in a position as shown in the figure. Figure 3 The state of being close to each other as shown, or making the two blades 50 be in a state as shown Figure 4 The driving unit is used to drive the movable seat 30 to move relative to the support plate 10, so that the movable seat 30 can move between a first position away from the bracket 20 and a second position close to the bracket 20. When the movable seat 30 moves from the first position to the second position, the movable seat 30 can drive the two blades 50 mounted thereon to move toward the bracket 20, and then the blades 50 can pass through the opening 22 of the groove 21 of the bracket 20 and extend into the interior of the groove 21. When the blades 50 move in the above manner, the blades 50 can hit the eggs after extending into the interior of the groove 21. The eggshell is broken so that the blade 50 can extend into the egg. Driven by the driving assembly, the two blades 50 that are close to each other open to each other, and the parts on both sides of the eggshell gap can be peeled outward at the gap where the eggshell is broken, so that the eggshell is peeled off, and the egg liquid inside the eggshell flows downward through the gap where the eggshell is peeled off, and falls downward from the egg liquid drop port on the support plate 10 located just below the bracket 20 into the frying pan of the egg frying machine. After completing the eggshell breaking action, the driving unit drives the movable seat 30 to move to the first position, and the driving assembly drives the two blades 50 to move to a state of being close to each other, preparing for the next eggshell breaking action.

[0031] In the utility model, a driving unit is utilized to drive the movable seat to move from a first position to a second position, two blades approaching each other knock open the eggshell, and a driving component drives the two blades to open each other, and the two blades are utilized to peel off the eggshell at the gap where the eggshell is broken. The eggshell has a relatively large gap, so that the egg liquid can flow out smoothly and quickly from the gap where the eggshell is broken, thereby accelerating the separation rate of the egg liquid and the eggshell, and improving the efficiency of the egg frying machine.

[0032] The movable seat 30 is slidably mounted on the support plate 10 through a linear guide pair, so that the movable seat 30 can drive the two blades approaching each other to accurately hit the middle position of the eggshell. Specifically, the linear guide pair includes a linear guide 31 fixedly connected to the support plate 10, and a slider 32 slidably mounted on the linear guide, and the movable seat 30 is fixedly connected to the slider 32. In other embodiments, a slide groove may be provided on the support plate 10, and the movable seat 30 may be slidably mounted in the slide groove to guide the movement of the movable seat 30.

[0033] In a preferred embodiment, the driving assembly includes a driving member, two swinging rods 62, and two connecting rods 61. The ends of the two swinging rods 62 away from the bracket 20 are respectively pivoted on the movable seat 30 through a first rotating shaft 621. The two blades 50 are respectively fixedly connected to the ends of the two swinging rods 62 close to the bracket 20. One end of the two connecting rods 61 is respectively pivoted to the middle of the swinging rods 62 through a second rotating shaft 622. The other ends of the two connecting rods 61 and the output end of the driving member are pivoted together through a third rotating shaft 611 that crosses the three. The output end of the driving member is used to drive the third rotating shaft 611 to move horizontally between a position close to the bracket 20 and a position away from the bracket 20, thereby making the other ends of the two connecting rods 61 (i.e., the ends connected to the third rotating shaft 611) approach or move away from the bracket 20. The driving member can specifically be a linear motor 60. The body of the linear motor 60 is fixed on the movable seat 30. The third rotating shaft 611 crosses the telescopic rod of the linear motor 60 and the other ends of the two connecting rods 61. Figure 3 As shown, the two blades 50 are in a state of being close to each other, the linear motor 60 is started, and the telescopic rod of the linear motor 60 pushes the third rotating shaft 611 to move in the direction close to the bracket 20, and the two connecting rods 61 respectively push the two swinging rods 62 toward the two sides of the movable seat 30, so that the two swinging rods 62 swing away from each other at the same time, and then drive the two blades 50 to gradually open to each other, and finally make the two blades 50 open to the position as shown in FIG. Figure 4 It should be emphasized that the linear motor 60 is used as a driving member to drive the third rotating shaft 611 to translate along a straight line. In other embodiments, the driving member is not limited to the linear motor 60, and it can also be a cylinder, an electromagnetic push rod, etc. that can drive the third rotating shaft 611 to translate along a straight line.

[0034] The swing lever 62 includes a first extension section 623 and a third extension section 624. The blade 50 is fixedly connected to one end of the second extension section 624. The end of the first extension section 623 away from the bracket 20 is pivoted to the movable seat 30 through a first rotating shaft 621. The other end of the second extension section 624 is connected to the end of the first extension section 623 close to the bracket 20 through a bending portion 625. The two swing levers 62 are symmetrically arranged on both sides of the movable seat 30. The swing lever 62 forms an L-shaped structure through the bending portion 625, the first extension section 623 and the second extension section 624. The bending angle at the bending portion 625 is 90° or approximately 90°. When the two blades 50 are in Figure 3 When the two blades 50 are in the state of being close to each other, the first extension section 623 and the second extension section 624 of the swing arm 62 are aligned with the side wall of the movable seat 30 and the end wall close to the bracket 20 respectively. Under the premise of ensuring that the driving assembly can normally drive the two blades 50 to separate or move together, the driving assembly occupies as little space as possible, making the structure of the entire eggshell breaking mechanism more compact and occupying relatively less space inside the egg frying machine, which is beneficial to the space utilization inside the egg frying machine.

[0035] The driving unit is an electromagnetic push rod 40 installed on the support plate 10. The electromagnetic push rod 40 is located on one side of the movable seat 30. The telescopic rod of the electromagnetic push rod 40 is fixedly connected to the movable seat 30 to drive the movable seat 30 to move between the first position and the second position. In order to facilitate assembly, a clamping block 41 is fixedly connected to the telescopic rod of the electromagnetic push rod 40. A connecting arm 33 is protruding from one side of the movable seat 30 close to the electromagnetic push rod 40. The connecting arm 33 is provided with a clamping groove 331. The clamping block 41 is embedded in the clamping groove 331, so that the clamping block 41 and the connecting arm 33 are fixed together by clamping, and then the telescopic rod of the electromagnetic push rod 40 and the connecting arm 33 are fixedly connected together. In other embodiments, the driving unit can also be a component that can drive the movable seat 30 to move between the first position and the second position, such as a cylinder, a linear motor, etc.

[0036] See also Figure 5 As shown, a blade 51 is formed on one side of the blade 50 close to the bracket 20. The blade 51 is in an arc shape with a middle portion concave in a direction away from the bracket 20. When the blade 50 hits the eggshell, the contact area between the arc-shaped blade and the surface of the eggshell is large, and a long gap can be hit on the eggshell. When the two blades 50 are opened, it is helpful to peel off the eggshell and prevent the eggshell from producing a lot of debris mixed into the egg liquid.

[0037] A protective cover 70 is fixedly connected to the movable seat 30. The protective cover 70 is located above the driving assembly and shields the driving assembly. The protective cover 70 provides protection for the movable seat 30 and the driving assembly to ensure that the driving assembly can work continuously and stably.

[0038] The egg frying machine of the utility model comprises the above-mentioned egg shell breaking mechanism, and other structures of the egg frying machine are the same as those in the prior art, which will not be described in detail here.

[0039] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
