[0008] A further improvement of the above-mentioned technical solution of this utility model is that: the cleaning part includes a cleaning plate hinged to the conversion column base, the pancake spreading part includes a pancake spreading frame hinged to the conversion column base, a pancake spreading frame is provided on one side of the pancake spreading frame, and a spreading panel that can move along the length direction of the pancake spreading frame is provided on one side of the pancake spreading frame; wherein, the cleaning plate and the pancake spreading frame are both converted to different states by telescopic rods.

[0009] A further improvement of the present invention is that the extrusion device includes a storage tank that is internally divided into multiple storage troughs by a partition. The bottom of the storage tank is provided with multiple discharge ports that correspond one-to-one with the multiple storage troughs. At the same time, each storage trough is provided with a drive motor, and the output shaft of the drive motor is fixedly connected to an auger extending towards the discharge port.

[0014] A further improvement of the present invention is that the pancake flipper device includes a scraper and a flipping rod located above the rotating baking pan and capable of moving along the timing belt. A pancake clamping device is provided on the side of the scraper facing the flipping rod, which works in conjunction with the scraper to clamp the pancake. The scraper and the flipping rod are located at both ends of the timing belt, and a buffer plate is provided between the scraper and the pancake clamping device to prevent damage to the pancake.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by this utility model includes:

[0016] This invention features a conversion column device that cleans the rotating baking pan and applies oil after cleaning, facilitating subsequent pancake production. Simultaneously, an extrusion device extrudes batter from the oiled pan, and the conversion column evenly spreads the extruded batter onto the pan. The rotating pan then heats and dries the batter until it sets. An egg-opening device transfers egg liquid to the set pancake, while the conversion column spreads the egg liquid evenly. A pancake flipper flips the egg-coated pancake, and the extrusion device applies sauce. Finally, a pancake-rolling device places crispy crackers from the crispy cracker conveyor onto the pancake and folds it into shape, thus achieving fully automated pancake production while eliminating manual labor.

[0017] In this invention, the cleaning plate allows for the cleaning of the rotating baking pan before pancake making. The edible oil in the oil tank is transported to the groove of the oil brush plate via an oil pipe, where it is evenly distributed on the brush, thus spreading the oil onto the rotating baking pan. Furthermore, because the spreading board can move along the length of the spreading frame, it allows for maximum movement within the limited range of the frame, resulting in a more even application of the batter onto the rotating baking pan.

[0018] In this invention, the drive motor and auger enable the batter or sauce in the storage bin to be orderly and quantitatively discharged onto the rotating baking pan.

[0019] In this invention, the egg opener motor, the egg opening wall, and the suction cup work together to hold the egg at the end of the egg slide rail and crack it open. After the egg is opened, the egg liquid falls onto the pancake through the egg liquid slide rail, and the egg shell on the suction cup is placed in the egg shell groove, thereby emptying the suction cup and preparing it to absorb the next egg.

[0020] In this invention, a thin crisp plate is provided for placing the crispy pieces, and a conveyor belt can drive the thin crisp plate to rotate in the vertical direction, so that the crispy pieces on the thin crisp plate fall onto the folding plate in an orderly manner.

[0021] In this invention, a rotary motor drives a gear to rotate, which causes the rack and the support to move horizontally. Through the cooperation of the horizontal movement of the support and the circumferential rotation of the folding plate in the vertical direction, it is convenient to place the falling crispy crackers on the pancake and fold the prepared pancake.

[0022] In this invention, a scraper is designed to separate the pancake from the rotating baking pan. The scraper and the buffer plate work together to clamp the edges of the separated pancake. After clamping the edges of the pancake, the scraper and the flipping stick work together to flip the pancake onto the rotating baking pan. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of this utility model.

[0041] refer to Figure 1 and Figure 2 As can be seen, this utility model includes a rotating baking pan 1, which can be an electrically heated rotating baking pan 1 commonly used in the prior art. In this embodiment, the rotating baking pan 1 is fixedly installed on the base. A conversion column device 2 fixed on the base is provided above the rotating baking pan 1. An extrusion device 3 is provided on one side of the conversion column device 2. An egg-opening device 4, a thin crisp conveying device 5, and a pancake rolling device 6 are arranged sequentially from top to bottom on the other side of the conversion column device 2. This utility model also includes a pancake flipping device 7.

[0042] In operation, this invention first cleans the rotating baking pan 1 using the conversion column device 2, and then applies oil to the rotating baking pan 1 after cleaning. Next, the extrusion device 3 extrudes batter from the oiled rotating baking pan 1, and the conversion column device 2 evenly spreads the extruded batter onto the rotating baking pan 1. The rotating baking pan 1 heats and dries the batter until it sets. Then, the egg-opening device 4 transfers the egg liquid to the set pancake, while the conversion column device 2 evenly spreads the egg liquid onto the pancake. Next, the pancake flipping device 7 flips the pancake with the egg liquid, and the extrusion device 3 applies sauce to the flipped pancake. Finally, the pancake rolling device 6 places the crispy crackers from the crispy cracker conveyor 5 onto the pancake and folds it into shape, completing the fully automated production of the pancake.

[0043] In this utility model, the conversion column device 2 is specifically set up with reference to... Figure 3 It is understood that the conversion column device 2 includes a conversion column base 21 located above the rotating baking pan 1, and the bottom of the conversion column base 21 is provided with a cleaning part 22, an oil conveying part 23, and a pancake spreading part 24. Specifically, in this embodiment, the conversion column base 21 is located above the center of the rotating baking pan 1, and the conversion column base 21 is located at the bottom of the conversion column and can rotate circumferentially. In this embodiment, a top plate is fixedly connected to the top of the conversion column, and the top plate is fixed to the base by a support leg. At the same time, in this embodiment, the rotation of the conversion column base 21 can be achieved by a motor inside the conversion column. Specifically, a motor slot is opened inside the conversion column, and a motor is fixedly connected in the motor slot. The top of the conversion column base 21 extends into the motor slot and is coaxially fixedly connected to the output shaft of the motor, thereby driving the conversion column base 21 to rotate through the motor.

[0044] In this embodiment, the cleaning section 22, the oil delivery section 23, and the pancake spreading section 24 are located at the bottom of the conversion column base 21 and are evenly arranged circumferentially with the center of the conversion column base 21 as the center. Specifically, the cleaning section 22 includes a cleaning plate 222 hinged to the conversion column base 21 via a first connecting rod 221, and the first connecting rod 221 is perpendicular to the cleaning plate 222. The pancake spreading section 24 includes a pancake spreading frame 242 hinged to the conversion column base 21 via a second connecting rod 241, and the second connecting rod 241 is perpendicular to the pancake spreading frame 242. In this embodiment, a spreading frame 243 is fixedly connected to one side of the spreading frame 242, and a spreading panel 244 is provided on the side of the spreading frame 243 away from the spreading frame 242. The spreading panel 244 can move along the length of the spreading frame 243. The movement of the spreading panel 244 can be in various ways (such as pneumatic, electric, or...). (Hydraulic, etc.) In this embodiment, the spreading frame 243 is based on the principle that the pancake spreading frame 242 has a groove 245 along its length on one side. The spreading panel 244 is provided with a slider that cooperates with the groove 245 on the side close to the spreading frame 243. At the same time, a strip groove 246 is fixedly connected to the top of the spreading panel 244. A rocker arm 247 is provided between the strip groove 246 and the top of the spreading panel 244. Specifically, the rocker arm 247 can be an electric push rod commonly used in the prior art. One end of the rocker arm 247 is located in the strip groove 246 and can move along the strip groove 246. The other end of the rocker arm 247 is hinged to the top of the spreading panel 244. By extending and retracting the rocker arm 247, the spreading panel 244 can move along the groove 245, thereby increasing the contact area between the spreading part 24 and the rotating baking tray 1, so that the batter is spread more evenly.

[0045] In this invention, to prevent interference between the cleaning section 22 and the pancake-spreading section 24 during use, both sections are switchable between vertical and horizontal states. When in the horizontal state, both sections are in contact with the rotating baking tray 1. In this embodiment, telescopic rods 25 are hinged between the cleaning plate 222 and the conversion column 21, and between the pancake-spreading frame 242 and the conversion column 21. These telescopic rods 25 can be electric, hydraulic, or pneumatic rods commonly used in the prior art. When the telescopic rod 25 is in the retracted state, the cleaning section 22 and the pancake-spreading section 24 are in a vertical state; when the telescopic rod 25 is in the extended state, the cleaning section 22 and the pancake-spreading section 24 are in a horizontal state and in contact with the rotating baking tray 1.

[0046] refer to Figure 1 and Figure 3As can be seen, the oil conveying part 23 of this utility model includes an oil brush plate 231 connected to the conversion column base 21. The oil brush plate 231 and the conversion column base 21 can be hinged or fixedly connected. When the oil brush plate 231 and the conversion column base 21 are hinged, the connection method between them is the same as the connection method between the cleaning plate 222 and the conversion column base 21, and between the pancake rack 242 and the conversion column base 21. At this time, the oil brush plate 231 also has two states: vertical and horizontal. When the oil brush plate 231 is in the horizontal state, the bottoms of the oil brush plate 231 are in contact. In this embodiment, the oil brush plate 231 is fixedly connected to the conversion column base 21 and is parallel to the rotating baking pan 1. At the same time, an oil brush 232 is fixedly connected to the bottom of the oil brush plate 231. A groove 233 for connecting the oil brush 232 is opened on the oil brush plate 231. The groove 233 is connected to an external oil storage tank containing edible oil through an oil conveying pipe. Furthermore, the oil brush 231 can be fixedly connected to the conversion column base 21 via a vertically arranged telescopic rod 25 (electric rod, hydraulic rod or pneumatic rod). When the telescopic rod 25 is in the retracted state, the oil brush 232 and the rotating baking tray 1 are separated; when the telescopic rod 25 is in the extended state, the oil brush 232 contacts the rotating baking tray 1, and the edible oil in the oil storage tank enters the oil brush 232 through the oil pipe and groove 233. The conversion column base 21 drives the oil brush 232 to rotate, which can evenly brush the edible oil onto the rotating baking tray 1.

[0047] refer to Figure 1 , Figure 2 and Figure 7 As can be seen, the extrusion device 3 of this utility model includes a storage tank 31 located above the rotating baking pan 1. Multiple partitions are fixedly connected inside the storage tank 31, which divide the internal space of the storage tank 31 into multiple storage slots. Different storage slots can hold batter and sauces of different flavors. At the same time, the bottom of the storage slots is provided with discharge ports 32 corresponding to the multiple storage slots. Each storage slot is fixedly connected with a drive motor 33. The output shaft of the drive motor 33 is coaxially fixedly connected to an auger 34 extending from the corresponding discharge port 32. In this embodiment, two storage bins 31 are provided, and each storage bin 31 is fixed to the top plate by a rotating rod 35. The rotating rod 35 can be an electric rotating rod commonly used in the prior art. When the extrusion device 3 is needed, the storage bin 31 is rotated to the upper part of the rotating baking pan 1 by the rotating rod 35; when the extrusion device 3 is not needed, the storage bin 31 is rotated to the outside of the rotating baking pan 1 by the rotating rod 35 to prevent the storage bin 31 from interfering with other components.

[0048] refer to Figure 2 and Figure 10As can be seen, the egg-opening device 4 of this utility model includes an egg slide rail 41 that is inclined downward toward the rotating baking pan 1. The end of the egg slide rail 41 is provided with an egg liquid slide rail 42 that extends toward the rotating baking pan 1. Above the end of the egg slide rail 41, two egg-opening walls 44 controlled by the egg opener motor 43 are arranged in a cross pattern. The end of each egg-opening wall 44 is provided with a suction cup 45 for adsorbing eggshells. At the same time, eggshell grooves 46 that cooperate with the suction cups 45 to place eggshells are provided on both sides of the egg liquid slide rail 42. In order to facilitate the eggshells on the suction cups 45 to enter the eggshell grooves 46, an inclined eggshell slide rail 461 is fixedly connected to the top of the eggshell grooves 46. The eggshells on the suction cups 45 fall onto the eggshell slide rail 461 and slide into the eggshell grooves 46. In this embodiment, the width of the egg slide rail 41 is slightly wider than the egg to avoid damaging the egg and affecting subsequent operations. An L-shaped baffle plate 47 is fixedly connected to the end of the egg slide rail 41. The suction cup 45 can be a pneumatic suction cup commonly used in the prior art. At the same time, the egg opener motor 43 can move up and down and horizontally. Specifically, horizontal plates 48 are fixed above both sides of the egg slide rail 41. Each horizontal plate 48 has an L-shaped groove 481, and the bend of the L-shaped groove 481 is arranged in an arc. The bottom of the egg opener motor 43 is fixedly connected to a bearing rod 431 with both ends located in the L-shaped groove 481. A sliding rod 482 is provided above the egg slide rail 41. Both ends of the sliding rod 482 are located in the horizontal section of the L-shaped groove 481, and the sliding rod 482 is connected to the bearing rod 431 through a third connecting rod 483. Specifically, the third connecting rod 483 is hinged to the sliding rod 482 and the bearing rod 431 respectively. Meanwhile, an electric push rod 49 is provided on the outer side of the horizontal plate 48. The two ends of the electric push rod 49 are respectively hinged to the two ends of the horizontal plate 48 and the slide rod 482. When the electric push rod 49 extends or retracts, it will drive the slide rod 482 to move along the horizontal section of the L-shaped groove 481, thereby driving the bearing rod 431 and the egg opener motor 43 to move along the L-shaped groove 481.

[0049] When the support rod 431 is located in the vertical section of the L-shaped groove 481, the egg opener motor 43 drives the two egg opening walls 44 to open. At this time, the two suction cups 45 move away from each other, and the egg on the egg slide rail 41 slides downwards under the action of gravity, with the lowest egg located on the blocking plate 47. At the same time, when the support rod 431 is located in the vertical section of the L-shaped groove 481, the suction cups 45 are aligned with the egg on the blocking plate 47, and then the egg opener motor 43 drives the two egg opening walls 44 to clamp together. At this time, the two suction cups 45 move closer together until the two suction cups 45 attract the egg on the blocking plate 47. Then, the electric push rod 49 is quickly extended and retracted, and the egg opener motor 43 drives the egg to move up and down along the vertical section of the L-shaped groove 481. When moving downwards, the egg will hit the blocking plate 47, thus breaking the egg. Then, the electric push rod 49 is extended, causing the slide rod 482 to move along the horizontal section of the L-shaped groove 481 towards the conversion column, and the support rod 431 follows the slide rod. 482 moves along the L-shaped groove 481. When the slide rod 482 moves to the end of the horizontal section of the L-shaped groove 481, the bearing rod 431 is located in the horizontal section of the L-shaped groove 481, and the cracked egg is located directly above the egg liquid slide rail 42. At this time, the egg opener motor 43 drives the two egg opening walls 44 to open, and the suction cup 45 breaks the cracked egg open. The egg liquid enters the egg liquid slide rail 42 and is transported to the rotating baking tray 1. At the same time, the inner wall of the egg liquid slide rail 42 is provided with uneven surfaces. The suction cup 45 is positioned above the eggshell groove 46, allowing the egg yolk to pierce the yolk as it flows within the egg yolk slide rail 42. When the suction cup 45 breaks the cracked egg, it is positioned directly above the eggshell groove 46. At this point, the suction cup 45 loses its suction force, and the eggshell falls into the eggshell groove 46, clearing the suction cup 45. Then, the electric push rod 49 retracts to its original position, and the support rod 431 and slide rod 482 also move to their original positions, facilitating the suction of the next egg that rolls onto the baffle plate 47.

[0050] refer to Figure 2 and Figure 9 As can be seen, the crispy crepe conveying device 5 of this utility model includes a vertically arranged conveyor belt 51 located below the egg slide rail 41, and a plurality of crispy crepe plates 52 for placing crispy crepes are evenly arranged on the conveyor belt 51. In this embodiment, the outer side of the conveyor belt 51 is covered with a shell 53. The top of the shell 53 should have a feeding port and the bottom should have a discharging port 32. The crispy crepes can be placed on the crispy crepe plates 52 located on the top of the conveyor belt 51 near the rotating baking tray 1 through the feeding port. Each crispy crepe plate 52 has one crispy crepe. When the crispy crepe plate 52 rotates to the bottom of the conveyor belt 51 and begins to tilt downwards, the crispy crepes on it will fall onto the wrapping device 6.

[0051] refer to Figure 2 and Figure 8As can be seen, the tortilla wrapping device 6 of this utility model includes a folded plate 61 capable of catching dropped thin, crispy pieces. The folded plate 61 is inclined toward the rotating baking pan 1 and can move and rotate in the direction of the rotating baking pan 1. In this embodiment, a support seat 62 is provided below the folded plate 61. The bottom end of the folded plate 61 is hinged to the end of the support seat 62 near the rotating baking pan 1. A push rod cylinder 63 is connected between the top end of the folded plate 61 and the other end of the support seat 62. Specifically, the two ends of the push rod cylinder 63 are respectively hinged to the top end of the folded plate 61 and the other end of the support seat 62. At the same time, a tortilla wrapping seat 64 is provided below the support seat 62. A rack 65 is fixedly connected to one side of the support seat 62 along its length direction. A gear 66 that meshes with the rack 65 is installed on one side of the support seat 62 through a rotary motor. When the crispy crackers fall through the discharge port 32, they land on the folding plate 61. The rotating motor then drives the gear 66 to rotate, causing the rack 65 and the support seat 62 to move towards the rotating baking pan 1. The pusher cylinder 63 then extends, causing the folding plate 61 to rotate clockwise, increasing the tilt angle until the crispy crackers on the folding plate 61 are flipped onto the pancake on the rotating baking pan 1. When the pancake needs to be folded, the tilt angle of the folding plate 61 should first be adjusted by adjusting the length of the pusher cylinder 63, so that the lower end of the folding plate 61 is flush with the top of the rotating baking pan 1. Then, the rotating motor drives the gear 66 to rotate, causing the rack 65 and the support seat 62 to move towards the rotating baking pan 1. At this time, the folding plate 61 lifts the pancake from the rotating baking pan 1. Then, the pusher cylinder 63 extends, causing the folding plate 61 to rotate clockwise, increasing the tilt angle until the pancake on the folding plate 61 is folded. Then, the rotating baking pan 1 drives the pancake to rotate, and the above steps are repeated to fold the folded part of the pancake.

[0052] refer to Figure 2 , Figure 4 , Figure 5 and Figure 6As can be seen, the pancake flipper device 7 of this utility model includes a scraper 71 and a flipping rod 72 located above the rotating baking pan 1. The scraper 71 and the flipping rod 72 are mounted on a synchronous belt 73 and move synchronously. In this embodiment, vertical plates 74 are fixedly connected to the base on both sides of the rotating baking pan 1. One of the vertical plates 74 has an elongated flipping groove 75 on its inner side. One end of the flipping groove 75 is provided with a drive wheel 731, which can be driven by a motor. The other end of the flipping groove 75 is provided with a driven wheel 732. The synchronous belt 73 is driven by the drive wheel 731 and the driven wheel 732. When the scraper 71 is located at one end of the drive wheel 731 of the synchronous belt 73, the flipping rod 72 is located at one end of the driven wheel 732 of the synchronous belt 73. At the same time, both the scraper 71 and the flipping rod 72 are connected to the synchronous belt 73 through a conveyor block 711, and the scraper 71 is facing the pancake. A pancake clamp 76 is provided on one side of the roller 72; at the same time, an annular groove 77 that cooperates with the conveying block 711 is provided on the inner side of another vertical plate 74, and a rail groove 78 that cooperates with the pancake clamp 76 is provided on the inner side of the annular groove 77. One end of the pancake clamp 76 is fixedly connected to a connecting block that can move within the rail groove 78. The distance between the bottom of the rail groove 78 and the bottom of the annular groove 77 is greater than the distance between the top of the rail groove 78 and the top of the annular groove 77. At the same time, a protrusion 781 extending into the annular groove 77 is provided at the bottom of the rail groove 78 corresponding to the position of the driven wheel 732, and a recess 782 extending into the rail groove 78 is provided at the top of the rail groove 78 corresponding to the position of the driving wheel 731.

[0053] Furthermore, in this embodiment, the pancake clamp 76 is connected to the scraper 71 via a limiting rod 712, and the side of the pancake clamp 76 facing the scraper 71 is connected to a buffer plate 79 via a buffer spring 791. In order to protect the pancake, the edges of the buffer plate 79 are all polished into a smooth transition.

[0054] When the pancake needs to be flipped, the scraper 71 is positioned at the bottom of the annular groove 77, corresponding to the drive wheel 731, and flush with the top of the rotating baking pan 1. At this time, the pancake clamp 76 and the buffer plate 79 are positioned at the bottom of the track groove 78, corresponding to the drive wheel 731, and the flipping stick 72 is positioned at the top of the annular groove 77, corresponding to the driven wheel 732. The timing belt 73 rotates counterclockwise, driving the scraper 71 to move to the right side of the rotating baking pan 1. The scraper 71 enters between the pancake and the rotating baking pan, while the flipping stick 72 moves to the left along the top of the annular groove 77 until the scraper 71 moves to the protrusion 781 at the bottom of the annular groove 77, corresponding to the driven wheel 732. At this time, the scraper 76 and the buffer plate 79 move towards the scraper 71 under the action of the protrusion 781, and the buffer spring 791 is compressed, thus... The punch plate 79 and scraper 71 work together to hold the right edge of the pancake in place. Then, the buffer plate 79 and scraper 71 continue to move under the action of the timing belt 73 and move to the left along the top of the annular groove 77. At this time, the flipping stick 72 moves to the bottom of the annular groove 77 and moves to the right. Through the cooperation of the buffer plate 79, scraper 71 and flipping stick 72, the pancake can be flipped on the rotating baking tray 1. When the buffer plate 79 and scraper 71 move to the recess 782 at the top of the annular groove 77 corresponding to the position of the drive wheel 731, the pancake clamp 76 and buffer plate 79 move away from the scraper 71 under the action of the recess 782. The buffer spring 791 is no longer compressed. At this time, the buffer plate 79 and scraper 71 release the clamped pancake, thus completing the entire pancake flipping operation.

[0055] The working principle of the pancake cooking robot in this embodiment is as follows:

[0056] First, the cleaning section 22 is switched to a horizontal position, and the rotating column 21 drives the cleaning section 22 to rotate and clean the rotating baking pan 1. Then, the cleaning section 22 is switched to a vertical position, and the oil conveying section 23 is rotated by the rotating column 21 to evenly spread cooking oil on the rotating baking pan 1. Then, a certain amount of batter is extruded into the rotating baking pan 1 through the extrusion device 3. Then, the pancake spreading section 24 is switched to a horizontal position to spread the batter evenly on the rotating baking pan 1. Then, the pancake spreading section 24 is switched to a vertical position, and the rotating baking pan 1 heats and dries the batter until it sets. Then, the egg liquid in the egg is transported to the set pancake through the egg-opening device 4. At the same time, the pancake spreading section 24 is switched to a horizontal position again to evenly spread the egg liquid on the pancake. Then, the pancake flipping device 7 flips the pancake with egg liquid, and at the same time, the extrusion device 3 spreads sauce on the flipped pancake. Finally, the pancake rolling device 6 places the crispy crisps in the crispy crisp conveying device 5 on the pancake and folds the pancake into shape, completing the fully automatic production of pancakes.

[0057] In the above embodiments, this utility model provides a fully automated pancake cooking robot. The robot features a conversion column device that cleans the rotating baking pan and applies oil after cleaning, facilitating subsequent pancake production. Simultaneously, an extrusion device extrudes batter from the oiled rotating baking pan, and the conversion column device evenly spreads the extruded batter onto the rotating baking pan. The rotating baking pan then heats and dries the batter until it sets. An egg-opening device transfers egg liquid to the set pancake, while the conversion column device evenly spreads the egg liquid onto the pancake. A pancake flipper flips the egg-coated pancake, and the extrusion device applies sauce to the flipped pancake. Finally, a pancake-rolling device places crispy crackers from the crispy cracker conveyor onto the pancake and folds it into shape, thus achieving fully automated pancake production while eliminating manual labor.
