Description

Technical Field

[0001] The utility model relates to the technical field of automatic cooking, in particular to an egg shell throwing mechanism and an egg frying machine. Background Art

[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] In the prior art egg frying machine, after the egg shell is broken by the egg shell breaking mechanism, the egg liquid falls downward from the bracket of the egg shell breaking mechanism into the frying pan, and the egg shell is pushed to both sides by the egg shell breaking blade when the egg shell is opened, so that the egg shell falls from both sides of the bracket. However, since the egg shell is adhered to the egg membrane attached to the inner wall of the egg shell when it is broken, the egg membrane cannot be completely torn when the blade opens the egg shell, and then the egg shell is difficult to fall off the bracket when the blade pushes the egg shell to both sides of the bracket. In addition, in order to facilitate the egg liquid to fall from the bracket, a support arm for supporting the egg is respectively arranged on both sides of the bracket. After the egg is placed on the bracket, its two sides are respectively supported by the two support arms, and the bottom of the egg sinks to a height position lower than the support arm. When the blade pushes the eggshell to both sides, the support arm will prevent the eggshell from falling from the side of the bracket, which also constitutes a factor to prevent the eggshell from falling from the side of the bracket. The broken eggshell may even fall from the part between the two support arms onto the frying pan. Utility Model Content

[0030] like Figure 1 , 23, an eggshell throwing mechanism of the utility model comprises a support plate 10, a bracket 20, and a driving assembly. The bracket 20 is located above the support plate 10 and is used to support poultry eggs. The eggshells of the poultry eggs are broken by the eggshell breaking blades of the egg frying machine on the bracket 20, and then the bracket 20 is turned over by the driving assembly to throw out the eggshells; an egg liquid drop opening 12 and an eggshell drop opening 13 located below the bracket 20 are provided on the support plate 10, and an egg liquid drop opening 12 and an eggshell drop opening 13 located below the bracket 20 are provided on the support plate 10. The portion between the egg liquid drop opening 12 and the egg shell drop opening 13 forms a connecting portion 101, and the connecting portion 101 separates the egg liquid drop opening 12 from the egg shell drop opening 13; the bracket 20 includes a first bracket arm 21, a second bracket arm 22 and a back plate 23, the first bracket arm 21 and the second bracket arm 22 are respectively located on both sides of the bracket 20, the back plate 23 is connected between the same ends of the first bracket arm 21 and the second bracket arm 22, and the first bracket arm 21 is rotatably connected to the connecting portion 101 through a pivot. On the part 101, the driving assembly is used to drive the bracket 20 to rotate around the pivot, so that the bracket 20 can swing between a first position located just above the egg liquid falling opening 12 and a second position flipped over to the eggshell falling opening 13. When the bracket 20 is in the first position, the first support arm 21 and the second support arm 22 of the bracket 20 are respectively located on both sides above the egg liquid falling opening 12, so that the groove between the first support arm 21 and the second support arm 22 on the bracket 20 is located just above the egg liquid falling opening 12. When the eggshell is broken, the first support arm 21 and the second support arm 22 respectively support the two sides of the eggshell, and the eggshell is broken from the middle, so that the egg liquid falls downward from between the first support arm 21 and the second support arm 22 through the egg liquid falling opening 12; the bracket 20 is flipped from the first position to the second position by the driving assembly, so that the angle of the flipping of the bracket 20 is greater than 90 degrees, so that the bracket 20 is located above the eggshell falling opening 13, and the eggshell located on the bracket 20 is thrown out from the eggshell falling opening 13.

[0031] Compared with the prior art, in the utility model, the bracket supports the poultry eggs when it is in the first position, and after the eggshell is broken on the bracket, the egg liquid falls from the egg liquid falling port, and then the bracket is driven to flip to the second position by the driving component. When the bracket is flipped to the second position, the bracket drives the eggshell to rotate above the eggshell falling port, so that the eggshell is thrown into the eggshell falling port. Since the eggshell is thrown out by flipping the bracket, after the egg liquid is separated from the eggshell, the eggshell can be quickly thrown into the eggshell falling port, and the eggshell is prevented from falling from the egg liquid falling port. After completing the eggshell throwing action, the bracket is driven by the driving component to flip to the first position, to receive the next poultry egg, and to prepare for the next eggshell breaking and eggshell throwing action.

[0032] The driving assembly of the utility model is located on the side of the egg liquid drop opening 12 away from the egg shell drop opening 13, and includes a linear motor 30 and a connecting rod 31. The body of the linear motor 30 is fixedly connected to the support plate 10, one end of the connecting rod 31 is hinged on the telescopic rod of the linear motor 30, and the other end is connected to the back plate 23 of the bracket 20 through a rotating shaft 32. The rotating shaft 32 is parallel to the above-mentioned pivot and staggered at a certain distance from each other; see Figure 4 As shown, when the bracket 20 is in the first position, the rotating shaft of the linear motor 30 is in a retracted state; Figure 5 As shown, the linear motor 30 is started, and the telescopic rod of the linear motor 30 extends to push the connecting rod 31 to move, and the connecting rod 31 pushes the rotating shaft 32 to rotate the bracket 20 around the pivot to the second position. In order to facilitate the installation of the bracket 20, the above-mentioned pivot includes two bolts 24 respectively screwed on the two ends of the first bracket 21, and bushings 25 respectively sleeved on the two bolts 24, and the two bolts 24 are coaxially arranged; two connecting ears 11 with axial holes are fixed on the connecting part 101, and the two connecting ears 11 are arranged opposite to each other. The two bushings 25 are respectively embedded in the axial holes of the two connecting ears 11, and the bushings 25 and the connecting ears 11 are rotatably matched, so that the bracket 20 can be rotatably installed on the connecting part 101. During assembly, the first bracket 21 is placed between the two connecting ears 11, and the two bolts 24 with the bushings 25 are respectively inserted from the outside of the two connecting ears 11, and then the bolts 24 are screwed to the end of the first bracket 21. See. Figure 1 , 5 As shown, an avoidance recess 311 is provided at the bottom of the connecting rod 31, and the avoidance recess 311 is used to avoid the bolt 24 close to the connecting rod 31 when the bracket 20 is in the second position. When the connecting rod 31 pushes the bracket 20 to swing, the connecting rod 31 itself will swing downward at a certain angle. By providing the avoidance recess 311, the interference between the connecting rod 31 and the bolt 24 can be avoided to ensure that the connecting rod 31 can swing downward at a relatively large angle, thereby ensuring that the bracket 20 can swing outward at a larger angle. Generally speaking, by providing the above-mentioned recess 311, the outward swing angle of the bracket 20 when it is in the second position can be greater than 105°. The bracket 20 with a larger swing angle can ensure that the eggshell is detached from the bracket 20 as much as possible.

[0033] An isolation net is provided below the support plate 10, and the isolation net is located just below the egg liquid drop opening 12. When the egg shell falls abnormally from the egg liquid drop opening 12, the isolation net can be used to catch the egg shell to prevent the egg shell from falling onto the frying pan of the egg frying machine along with the egg liquid.

[0034] A guide groove 14 is provided below the support plate 10 at the eggshell drop opening 13. The guide groove 14 is surrounded by an inclined bottom wall and two side walls. The top of the inclined bottom wall is connected to the bottom of the connecting portion 101, and the inclined bottom wall gradually extends from top to bottom in a direction away from the egg liquid drop opening 12. The two side walls are respectively located on both sides of the inclined bottom wall. The tops of the two side walls are respectively connected to the lower surface of the support plate 10 at positions on both sides of the eggshell drop opening 13. The eggshells thrown out by the bracket 20 are received through the guide groove 14 to facilitate the centralized recovery of the eggshells.

[0035] A circle of upwardly extending barriers 15 is provided on the upper surface of the support plate 10 at the positions of the egg liquid drop opening 12, the egg shell drop opening 13 and the periphery of the connecting portion 101, and the barriers 15 are used to shield the egg liquid drop opening 12, the egg shell drop opening 13 to prevent dust and other impurities from contaminating the egg liquid through the egg liquid drop opening 12.

[0036] In order to better support the poultry eggs, the utility model sets the upper surfaces of the first support arm 21 and the second support arm 22 to a structure that is low in the middle and high on both sides. Taking the first support arm 21 as an example, a block 211 is set above the two ends of the first support arm 21. The two blocks 211 make the positions of the two ends of the upper surface of the first support arm 21 higher, and the part between the two blocks 211 is a concave structure. The second support arm 22 has the same structure as the first support arm 21, and no repeated description is made here; through the above-mentioned structure of the first support arm 21 and the second support arm 22, when the bracket 20 supports poultry eggs, the poultry eggs are prevented from rolling on the bracket 20.

[0037] The driving component of the utility model is not limited to the above-mentioned structure of the linear motor and the connecting rod. It can also include a motor, the output end of the motor is connected to the bracket 20, and the bracket 20 is directly driven to rotate by the motor. In order to increase the torque, a reducer can be installed at the output end of the motor, and the output end of the reducer is connected to the bracket 20.

[0038] The egg frying machine of the utility model comprises the egg shell ejecting mechanism. The other structures of the egg frying machine are the same as those in the prior art and 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.
