[0021] Please also read Figures 1 to 10 The automatic pancake machine provided by the present invention is now described. The automatic pancake machine comprises a frame 1 and a heating plate 11, a spreading plate 12 and a finishing unit 13 arranged on the frame 1 in sequence. The heating plate 11 is rotatably connected to the frame 1 and is used to form pancake skins. A batter supply unit 2 and an egg supply unit 3 are arranged above the heating plate 11. A spreading plate 111 with a plate surface extending in the up-down direction and a separation arc plate 113 that can be translated toward one side of the center of the heating plate 11 to separate the pancake skin from the heating plate 11 are arranged on the side of the spreading plate 12. A spreading unit 4 and a crisp supply unit 5 are arranged above the spreading plate 12. The finishing unit 13 is used to fold the pancake skin to form a pancake. A dragging unit located on the side of the heating plate 11, the spreading plate 12 and the finishing unit 13 is arranged on the frame 1. The dragging unit is used to transfer the pancake skin from the heating plate 11 to the spreading plate 12 or from the spreading plate 12 to the finishing unit 13.

[0022] Compared with the prior art, the automatic pancake machine provided by the present embodiment can automatically sprinkle batter and eggs onto the heating plate 11 in sequence, flatten the pancake with the spreading plate 111, and separate the pancake skin from the heating plate 11 with the help of the separation arc plate 113, and then drag the pancake skin to the spreading plate 12 for spreading and laying crisps by the dragging unit, and then the dragging unit transfers the pancake skin and crisps to the sorting unit 13 for sorting, and folds them into pancakes for customers to eat. The above-mentioned automatic pancake machine eliminates the tedious manual operation, reduces the cost of making pancakes, meets the consumption needs of customers anytime and anywhere, and ensures the safety and hygiene of food.

[0023] In this embodiment, the heating plate 11 is rotatably connected to the frame 1, and can be used to heat the batter and eggs to shape them by electric heating or oil heating. First, a predetermined amount of batter is supplied to the heating plate 11 by the batter supply unit 2, and the spreading plate 111 is connected to the frame 1 through the lifting assembly 112. When it is necessary to spread the batter, the lifting assembly 112 drives the spreading plate 111 to move downward to evenly spread the batter on the heating plate 11. After the batter is formed, the egg supply unit 3 supplies a single egg to the top of the heating plate 11 and breaks it so that the egg liquid falls onto the pancake skin, and then the egg is spread on the pancake skin with the help of the spreading plate 111. After forming, the pancake skin is separated from the heating plate 11 by the separation arc plate 113 moving horizontally and extending between the pancake skin and the heating plate 11.

[0024] Next, the pancake skin is dragged from the heating plate 11 to the spreading plate 12 by the dragging unit, the spreading unit 4 sprinkles the small ingredients on the pancake skin, and the crispy chip supply unit 5 unloads the crispy chips onto the pancake skin. Finally, the pancake skin with the crispy chips is transferred to the sorting unit 13 for sorting and folding by the dragging unit, completing the whole pancake making process.

[0025] Among them, the small ingredients scattered by the scattering unit 4 include sauces, powders, and auxiliary vegetable ingredients such as chopped green onions and coriander, and different types can be selected according to the actual needs of customers.

[0026] The automatic pancake machine can quickly and accurately complete the production and transaction of pancakes, improve service efficiency, reduce waiting time, and enhance consumer experience. At the same time, it can provide personalized services by adding corresponding small ingredients according to the needs and taste preferences of consumers. It is suitable for various environments and scenes, such as shopping malls, schools, stations and other public places, and can also adapt to various climate and weather conditions.

[0027] It should be noted that the rack 1 in the attached drawings can be open or closed. The closed type can improve hygiene and can also be automatically sold by setting an automatic selling program. In order to facilitate the installation of the batter supply unit 2, the egg supply unit 3, the material spreading unit 4 and the crisp supply unit 5, the rack 1 is provided with an upper plate 17 located above the heating plate 11. The batter supply unit 2, the egg supply unit 3, the material spreading unit 4 and the crisp supply unit 5 are installed on the upper plate 17 and extend downward through the upper plate 17.

[0028] In one possible implementation, see Figures 1 to 10 The batter supply unit 2 includes a mixing barrel 21 and a plurality of raw material barrels 22 located above the mixing barrel 21 and used to contain raw materials or water. A feeding pipe 23 for feeding materials into the mixing barrel 21 is provided at the bottom of the raw material barrel 22. A control valve is provided on the feeding pipe 23. A mixing blade for mixing raw materials and water to form batter is rotatably connected in the mixing barrel 21.

[0029] In this embodiment, when making the dough, different raw materials such as millet flour, bean flour and water are respectively contained in a plurality of raw material barrels 22. The different raw materials are fed into the mixing barrel 21 through the feeding pipe 23, and the materials are stirred by the stirring blades in the mixing barrel 21 to achieve the mixing and making of the dough.

[0030] The control valve on the feeding pipe 23 can control the feeding amount of different raw materials. By setting a control unit and setting a preset program in the control unit, the discharge amount of different valves can be controlled to quantitatively add different materials. The stirring blade can rotate to fully stir and mix the above raw materials to form a uniform batter. Before feeding the batter to the heating plate 11 below, the stirring step should be repeated to prevent the batter from precipitating and affecting the molding quality of the pancake skin.

[0031] In one possible implementation, see Figures 1 to 10 The egg supply unit 3 includes an egg box 31, an egg outlet assembly 32, an egg delivery track 33 and an egg beating assembly 7. The egg box 31 is provided with an egg cavity for accommodating a single egg. The egg outlet assembly 32 is arranged below the egg box 31 and is used to block or open the lower opening of any egg cavity. The egg delivery track 33 is located below the egg outlet assembly 32 and is used to receive eggs dropped from the egg cavity. The egg beating assembly 7 is arranged at the lower opening of the egg delivery track 33 and is used to open the eggshell to allow the egg liquid to fall onto the pancake skin.

[0032] In this embodiment, multiple egg cavities in the egg box 31 are used to accommodate individual eggs. The egg discharging assembly 32 can open the lower opening of the egg cavity. Different numbers of eggs are supplied according to the number of eggs required by the customer. The eggs fall onto the egg beating assembly 7 through the egg delivery track 33. The eggs are opened one by one by means of the egg beating assembly 7, so that the egg liquid falls onto the heating plate 11. Afterwards, the eggs are spread on the pancake skin by means of the spreading plate 111 to ensure the uniformity of the spreading and improve the taste of the customers.

[0033] For some examples, see Figures 1 to 10 In a possible implementation, the frame 1 is provided with an egg shell box 8 located below the egg feeding track 33 and a supporting plate 81 connected to the side of the egg shell box 8, the supporting plate 81 is provided with a liquid passage hole for egg liquid to pass through, the egg beating assembly 7 is rotatably connected to the supporting plate 81 through a rotating arm 82, and the output end of the rotating arm 82 is provided with a mounting plate 83 for mounting the egg beating assembly 7, the rotating arm 82 can drive the mounting plate 83 and the egg beating assembly 7 to swing vertically to transfer egg shells into the egg shell box 8, and the mounting plate 83 is provided with a through hole connected to the liquid passage hole.

[0034] In this embodiment, the support plate 81 provided on the frame 1 is used to support the egg beating assembly 7, and the liquid-passing hole provided on the support plate 81 allows the egg liquid to pass through and fall onto the pancake skin below. After the egg beating assembly 7 cracks the egg, the egg liquid falls onto the pancake skin through the through hole and the liquid-passing hole, and the eggshell is driven by the rotating arm 82 to be vertically flipped so that the eggshell can smoothly enter the eggshell box 8 to complete the egg beating process. The eggshell box 8 is provided with an eggshell opening 84 at the top or side to facilitate the entry of the eggshell. This setting can ensure the freshness of the eggs and the accuracy of the quantity. Compared with the traditional method of directly sprinkling egg liquid on the pancake skin, it is more hygienic and can better meet the customer's eating taste.

[0035] Furthermore, a push plate 79 is provided at the end of the middle rod 72, and the push plate 79 can effectively contact the egg shell to ensure effective pushing of the egg. The push plate 79 has an inner concave arc surface that can contact the egg shell to ensure effective pushing of the egg, which is convenient for the subsequent breaking tip 76 to perform egg beating operation.

[0036] For some examples, see Figures 1 to 10The egg beating assembly 7 includes a mounting bar 71, an intermediate rod 72, a linkage rod 73, an articulated arm 74 and a telescopic pusher 75. The mounting bar 71 is connected to the mounting plate 83 in the horizontal direction. The intermediate rod 72 is arranged perpendicular to the direction of the mounting bar 71 and penetrates the mounting bar 71 and is slidably connected to the mounting bar 71. Two articulated arms 74 are symmetrically arranged on both sides of the liquid hole and are hinged to the two ends of the mounting bar 71 in a one-to-one correspondence. Two linkage rods 73 are symmetrically arranged on both sides of the intermediate rod 72. The linkage rod 73 is hinged between the articulated arm 74 and the intermediate rod 72 to drive the two articulated arms 74 to swing synchronously. The articulated arm 74 is connected with a lower support plate 78 located above the through hole and used to support eggs. The ends of the two articulated arms 74 close to the through hole are provided with a crushing tip 76 extending to one side of the through hole. The ends of the two articulated arms 74 close to the through hole are connected by an elastic member 77. The telescopic pusher 75 is arranged at the end of the articulated arm 74 away from the through hole. Among them, under the pushing action of the telescopic pusher 75, the middle rod 72 can push the egg to make it close to the crushing tip 76, and the two crushing tips 76 can separate in the opposite direction to crush the eggshell and allow the egg liquid to fall onto the pancake skin through the through hole and the liquid hole.

[0037] In this embodiment, the middle rod 72 not only satisfies the requirement of pushing the eggs horizontally, but also cooperates with the linkage member to make the two articulated arms 74 change synchronously, eliminating the tediousness of setting two telescopic pushers 75, reducing the structural cost, and facilitating the reasonable distribution of space. The middle parts of the two articulated arms 74 are respectively hinged to the ends of the mounting strip 71, the middle rod 72 is arranged through the mounting strip 71, and the linkage rod 73 connects the middle rod 72 and the articulated arms 74, so that only one telescopic pusher 75 can be provided to form a driving effect on the two articulated arms 74.

[0038] When one of the articulated arms 74 is pushed by the telescopic pusher 75, the two articulated arms 74 move toward each other at one end away from the through hole through the action of the two linkage rods 73, realizing the linkage of the two articulated arms 74 and ensuring the consistency of their actions. The crushing tips 76 extend toward the center of the liquid hole. Under the pushing action of the telescopic pusher 75, the two crushing tips 76 of the two articulated arms 74 move in opposite directions to crush and separate the eggshells, completing the egg beating operation. Afterwards, the two articulated arms 74 are pulled back by the elastic member 77 and return to the initial state where the two crushing tips 76 contact each other.

[0039] In one possible implementation, see Figures 1 to 10 The egg cavities are arranged in a matrix on the egg box 31. The egg discharging assembly 32 includes a gear 34, a rack 35 and a cover strip 36. The gear 34 is meshed with the rack 35 to drive the rack 35 to translate. The cover strip 36 is connected to the rack 35 and is driven by the rack 35 to translate to open the lower openings of the egg cavities in the same row one by one. The frame 1 is also provided with a horizontal push driving member 37 for horizontally pushing the egg box 31 so that any row of egg cavities of the egg box 31 corresponds to the covering strip 36 up and down.

[0040] In this embodiment, in order to increase the number of eggs that can be accommodated, the egg cavities are arranged in a matrix, that is, a structure with multiple rows and columns. The gear 34 is rotated to drive the rack 35 to move, so that the cover strip 36 can be translated under the same row of egg cavities, so that the eggs can fall onto the egg delivery track 33 in sequence. When one row of eggs is used up, the push drive 37 on the frame 1 drives the entire egg tray to translate, so that the next row of egg cavities can correspond to the cover strip 36 up and down, so that the next row of eggs can be used for subsequent pancake making, thereby meeting the continuous supply of eggs.

[0041] In one possible implementation, see Figures 1 to 10 The dragging unit includes a first dragging unit 61 and a second dragging unit 62 arranged on both sides of the spreading unit 4. The first dragging unit 61 is located on the same side of the heating plate 11 and the spreading plate 12, and is used to transfer the pancake skin on the heating plate 11 to the spreading plate 12. The second dragging unit 62 is located on the same side of the spreading plate 12 and the sorting unit 13, and is used to transfer the pancake skin on the spreading plate 12 to the sorting unit 13; Among them, a horizontally extending transverse roller 14 is provided between the heating plate 11 and the spreading plate 12, and the extension direction of the transverse roller 14 is set perpendicular to the dragging direction of the first dragging unit 61. A transition platform 15 for supporting the pancake skin is provided between the spreading plate 12 and the sorting unit 13.

[0042] In this embodiment, two dragging units are provided, which are respectively located on both sides of the spreading tray 12, one for transferring the pancake skin on the heating tray 11 to the spreading tray 12, and the other for transferring the pancake skin on the spreading tray 12 to the sorting unit 13. Since the pancake skin and eggs on the heating tray 11 are in a solidified state after heating, a horizontal roller 14 can be provided between the heating tray 11 and the spreading tray 12 to assist the first dragging unit 61 in supporting the pancake skin and complete the position transfer of the pancake skin. After the pancake skin is sprinkled with small ingredients and crispy chips on the spreading tray 12, in order to prevent the small ingredients and crispy chips from falling, a transition platform 15 is provided between the spreading tray 12 and the sorting unit 13, which can assist the second dragging unit 62 in supporting the fried dough skin and crispy chips and prevent the small ingredients and crispy chips from falling during the transfer process.

[0043] On this basis, a cleaning brush 16 is also provided above the sorting unit 13. The cleaning brush 16 can move horizontally to clean the debris dropped from the sorting plate 131, the lower flap 132 and the side flap 133, ensuring that the surfaces of the above components are clean before sorting each pancake.

[0044] For some examples, see Figures 1 to 10 The first dragging unit 61 and the second dragging unit 62 each include a linear guide rail 63, a clamping cylinder 64 and a flexible clamping strip 65. The output end of the linear guide rail 63 is connected to an extension frame 66 extending horizontally toward a side close to the heating plate 11 and the spreading plate 12. The clamping cylinder 64 is connected to the extension end of the extension frame 66. The clamping cylinder 64 has two clamping claws spaced apart up and down. Two flexible clamping strips 65 are provided, and the two flexible clamping strips 65 are respectively connected to the two clamping claws one by one.

[0045] In this embodiment, the first drag unit 61 and the second drag unit 62 adopt the same structure, and both use the linear guide 63 to push the clamping cylinder 64 to achieve the position change between the heating plate 11, the spreading plate 12 and the sorting unit 13. The two clamping claws of the clamping cylinder 64 are respectively provided with flexible clamping strips 65, which can effectively clamp the edge of the pancake skin and drive it to move horizontally to complete the position transfer. The selection of the flexible clamping strips 65 can avoid damage to the pancake skin and improve the production quality of the pancake skin.

[0046] In one possible implementation, see Figures 1 to 10 The sorting unit 13 includes a sorting plate 131, a lower flap 132 and two side flaps 133. The sorting plate 131 is used to support the pancake skin with crispy chips. The side flaps 133 and the lower flap 132 are respectively arranged on the outer periphery of the sorting plate 131, and the two side flaps 133 are symmetrically located on both sides of the sorting plate 131. The side flap 133 and the lower flap 132 can be swung vertically to fold the corresponding edges of the pancake skin.

[0047] In this embodiment, the lower flap 132 and the side flap 133 are used to assist the sorting plate 131 in supporting the pancake skin and the crispy chips above. The lower flap 132 folds the lower edge of the pancake skin upward to the top of the sorting plate 131, and the side flaps 133 fold the edges on both sides toward the top of the sorting plate 131, so that the pancake skin is covered around the periphery of the crispy chips, making it easier for customers to eat.

[0048] In one possible implementation, see Figures 1 to 10 The crisp supply unit 5 and the spreading unit 4 both include a containing box 41 and a telescopic discharge plate 42.
