Automatic pizza making machine

Abstract

This invention discloses an automatic pizza-making machine, including a dough forming device, a conveying device, a sauce spreading device, multiple ingredient spreading devices, and a baking oven. The dough forming device presses fermented dough into pizza bases. The conveying device transports the pizza bases formed by the dough forming device to the sauce spreading station, where the sauce spreading devices spread sauce onto the surface of the pizza base. The conveying device then transports the pizza bases from the sauce spreading station to each ingredient spreading station, where the ingredient spreading devices spread their respective ingredients onto the pizza bases. Finally, the conveying device transports the pizza bases from the ingredient spreading stations to the baking oven for baking. This invention uses a mechanical conveying scheme with a bracket and bracket drive mechanism instead of a robotic arm, ensuring standardized pizza production while significantly reducing the manufacturing cost and maintenance difficulty of the pizza-making machine. This design significantly lowers the barrier to entry and operating costs of the pizza-making machine, making it particularly suitable for cost-sensitive small businesses such as fast food restaurants and convenience stores.

Description

Technical Field

[0001] This utility model belongs to the field of pizza making technology, specifically relating to an automatic pizza making machine. Background Technology

[0002] With the fast pace of modern life, fast food has become an important part of people's daily diet due to its convenience and diverse flavor options. Among them, pizza, with its rich combinations—changing sauces, cheeses, and various toppings can present completely different flavor characteristics—satisfies the need for quick satiety and adapts to the personalized preferences of different consumers, thus enjoying widespread popularity around the world.

[0003] Traditional pizza making involves multiple steps, including dough stretching, sauce application, topping, and baking. Manual production is inefficient and inconsistent in quality. Existing automation solutions often rely on high-precision robotic arms for material transfer and processing, such as the CN106170208A batch-production automatic pizza-making machine. While these machines improve production efficiency, their high equipment costs (primarily due to core components like servo systems and precision guide rails) and maintenance complexity make them unaffordable for small and medium-sized restaurant owners or businesses with limited budgets. Furthermore, the maintenance and programming of these robotic arms require specialized technical support, further increasing the barrier to entry and operating costs. Utility Model Content

[0004] To address the technical problems existing in the prior art, this utility model provides an automatic pizza making machine.

[0005] In this embodiment of the invention, an automatic pizza-making machine includes a dough forming device, a conveying device, a sauce spreading device, multiple ingredient spreading devices, and a baking oven. The dough forming device is used to press fermented dough into a pizza base. The conveying device includes a bracket and a bracket driving mechanism that drives the bracket to move. Under the action of the bracket driving mechanism, the bracket can carry the dough on it. The bracket of the conveying device can convey the pizza base made by the dough forming device to the sauce spreading station. The sauce spreading device can spread sauce on the surface of the pizza base at the sauce spreading station. The bracket of the conveying device can convey the pizza base at the sauce spreading station to each ingredient spreading station. The multiple ingredient spreading devices can spread their respective ingredients onto the pizza base at the corresponding ingredient spreading station. The bracket of the conveying device can also convey the pizza base at the ingredient spreading station to the baking oven for baking.

[0006] Compared with the prior art, the beneficial effects of the superior technical solution of this utility model include:

[0007] 1. Cost-optimized design. A mechanical conveying system using a bracket and its drive mechanism replaces the robotic arm, significantly reducing manufacturing costs and maintenance complexity while ensuring standardized pizza production. This design significantly lowers the barrier to entry and operating costs for the pizza-making machine, making it particularly suitable for cost-sensitive small businesses such as fast-food restaurants and convenience stores.

[0008] 2. Ease of operation. Operators only need to place the fermented dough into the dough forming device, and the equipment can automatically complete all subsequent production processes. The finished pizza can be taken directly out of the baking oven. The whole process is simple and efficient, greatly reducing the difficulty of manual operation.

[0009] 3. Optimized spatial layout. All functional modules (dough forming device, sauce spreading device, ingredient spreading device, and baking oven) are arranged in a straight line along the frame, forming a highly efficient integrated production line. This linear layout not only simplifies the structure of the conveying device and reduces equipment costs, but also saves floor space compared to traditional L-shaped production lines.

[0010] 4. Innovative dough pressing and shaping technique. Fermented dough often has irregular shapes and is not perfectly round. To solve this problem, this invention employs a two-stage pressing process: first, the irregular dough is initially pressed into a cylindrical shape by a column pressing component, and then the cylindrical dough is pressed a second time by a pressing component, ultimately forming a round dough with a regular shape and uniform thickness.

[0011] 5. Customized Flavor Solution. By setting up multiple meat slots and slot drive mechanisms, it is possible to quickly switch between various meats, which can meet the customized needs of different flavor pizzas and significantly enhance the diversity of product choices.

[0012] These technological innovations together constitute an efficient, economical, and flexible automated pizza production solution that optimizes production costs and space utilization while ensuring product quality. Attached Figure Description

Detailed Implementation

[0023] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] This embodiment provides an automatic pizza-making machine, such as... Figure 1 As shown, in a preferred embodiment, the pizza making machine includes a dough forming device 20, a conveying device 30, a sauce spreading device 40 located downstream of the dough forming device 20, a plurality of ingredient spreading devices located downstream of the sauce spreading device 40, and a baking oven 80 located downstream of the plurality of ingredient spreading devices.

[0025] In use, workers place the fermented dough into the dough forming device 20, which is used to press the fermented dough into dough sheets. The conveying device 30 includes a bracket 31 and a bracket drive mechanism that drives the bracket 31 to move. Under the action of the bracket drive mechanism, the bracket 31 can carry the dough sheet on it. Specifically, the bracket drive mechanism can drive the bracket 31 to move linearly and rotate horizontally along the frame slide rail 32 to convey the dough sheet to each workstation.

[0026] Specifically, the bracket 31 of the conveying device 30 can convey the dough made by the dough forming device 20 to the sauce spreading station 14. The sauce spreading device 40 can spread sauce, such as tomato sauce or chili sauce, on the surface of the dough at the sauce spreading station 14 as a base sauce. The bracket 31 of the conveying device 30 can convey the dough at the sauce spreading station 14 to each topping station. Multiple ingredient spreading devices can spread their respective ingredients (including cheese, vegetables and meat) onto the dough at the corresponding topping station. The bracket 31 of the conveying device 30 can also convey the dough at the topping station to the baking oven 80 for baking. The worker takes away the pizza baked in the baking oven 80.

[0027] like Figure 1As shown, in this invention, the dough forming device 20, conveying device 30, sauce spreading device 40, ingredient spreading device, and baking oven 80 are mounted on the frame 10. The dough forming device 20, sauce spreading device 40, ingredient spreading device, and baking oven 80 are arranged sequentially along the length (longitudinal) of the frame 10. The first end of the conveying device 30 is located near the dough forming device 20, and the last end of the conveying device 30 is located near the baking oven 80. The sauce spreading device 40 and multiple ingredient spreading devices are located outside the conveying device 30. The various processes of pizza making in this pizza-making machine are all in a straight line. The pizza-making machine is a cuboid, 3m long, 1.7m wide, and 1.8m high, with a small volume, reducing the floor space compared to an L-shaped production line. The bracket drive mechanism includes a linear drive mechanism (not shown in the figure) that drives the bracket 31 to move linearly along the length of the frame 10. Specifically, the linear drive mechanism can adopt a linear motor, electric cylinder, or rotary motor + lead screw structure as used in existing technologies.

[0028] like Figure 4 and Figure 5 As shown, preferably, two parallel frame slide rails 32 extending along the length of the frame 10 are fixedly connected to the frame 10, and a frame slide plate 33 spanning the two frame slide rails 32 is slidably connected to the two frame slide rails 32. The bracket 31 is installed on the frame slide plate 33, and the frame linear drive mechanism drives the frame slide plate 33 to move linearly on the frame slide rails 32 so that the bracket 31 moves along the length of the frame 10.

[0029] like Figures 1-3 As shown, in this utility model, a shell 11 is fixedly connected to the frame 10. The dough forming device 20, conveying device 30, sauce spreading device 40, ingredient spreading device, and baking oven 80 are located inside the shell 11. The shell 11 provides a more aesthetically pleasing enclosure for the various devices, and it can be made of sound-insulating and noise-reducing materials to reduce noise. The top of the shell 40 is open to facilitate the addition of ingredients to the sauce spreading device 40 and the ingredient spreading device. A dough inlet 12 is provided on the side of the shell 11 near the dough forming device 20, through which workers place the fermented dough into the dough forming device 20. A pizza outlet 13 is provided on the side of the shell 11 near the baking oven 80. After the pizza is baked, the baking oven 80 is opened, and the worker removes the baked pizza through the pizza outlet 13. Doors that can be opened and closed can also be provided at the dough inlet 12 and the pizza outlet 13 to improve the sound insulation and noise reduction effect.

[0030] like Figure 4As shown, in a preferred embodiment of this utility model, the dough forming device 20 includes a base plate 21 and a dough pressing assembly 22. The dough pressing assembly 22 includes a flattening block 221 with a cavity, and a dough driving mechanism 222 for driving the flattening block 221 to move vertically to flatten the dough on the base plate 21 into a dough sheet. The dough driving mechanism 222 can be a linear motor, an electric cylinder, or a rotary motor + lead screw structure that extends downward along the output axis and is mounted on the top of the frame 10. Figure 6 As shown, the cavity of the flattened block 221 is open at the lower end, and the top of the cavity has upwardly recessed grooves 223 around its perimeter. The grooves 223 cause the outer periphery of the dough to bulge upwards as the edge of the dough. The size of the base plate 21 is larger than the diameter of the pressed dough, and the inner diameter of the cavity of the flattened block 221 is approximately equal to the outer diameter of the dough.

[0031] The dough is placed on the base plate 21, which is supported by the frame 10. The pressing assembly 22 is located directly above the base plate 21. The pressing block 221 moves downward through the dough driving mechanism 222, pressing the dough on the base plate 21 into a flatbread. The circumference of the cavity of the pressing block 221 makes the pressed flatbread more rounded. The pressed flatbread is then removed by the bracket 31. Specifically, the process of pressing the dough into a flatbread is the same as the stamping process in the prior art, and will not be described in detail here.

[0032] In practice, the surface of the dough is coated with non-stick cooking oil, the inner surface of the cavity of the flattened block 221 is provided with a non-stick layer, which facilitates demolding, and the bracket 31 can remove the dough from the base plate 21.

[0033] Preferably, the flattened block 221 or the base plate 21 is provided with a heating unit (not shown in the figure) that can heat the dough on the base plate 21. The heating unit can be a heating plate or heating wire embedded inside. By heating the soft dough with the heating unit, the dough is shaped, which is convenient for the conveying device 30 to transfer the dough.

[0034] Because the risen dough is irregular in shape and not very round, it is directly pressed into a flatbread by the pressing component 22. The flatbread's outer edge is not round enough and is irregular, affecting its appearance. Figure 7 As shown, in another preferred embodiment, the dough forming device 20 further includes a column pressing component 23 located upstream of the dough pressing component 22. The base plate 21 can be located directly below the column pressing component 23, and the base plate 21 is connected to a base plate driving mechanism 24 that drives it to move below the column pressing component 23 and below the dough pressing component 22. The base plate driving mechanism 24 can employ a linear motor, electric cylinder, or rotary motor + lead screw structure as used in the prior art.

[0035] like Figure 4 and Figure 7As shown, preferably, the frame 10 is provided with two base plate slide rails 241 extending along its length. A base plate slider 242, which is fixed to the bottom of the base plate 21, is slidably connected to the base plate slide rails 241. The base plate drive mechanism 24 drives the base plate 21 to move linearly along the base plate slide rails 241 via the base plate slider 242, so that the base plate 21 moves to below the column pressing assembly 23 and below the pressing cake assembly 22. The end of the base plate slide rail 241 connects to the beginning of the frame slide rail 32, making them a continuous single slide rail.

[0036] The fermented dough is first pressed into a cylindrical shape by the column pressing component 23 (it is flat and the height is less than the diameter), and then the dough pressing component 22 presses the cylindrical dough into a flatbread, so that the flatbread has a more regular round shape.

[0037] like Figure 7 As shown, specifically, the column pressing assembly 23 includes a limiting bowl 231 with an annular sidewall that can be sealed by a base plate 21, a bowl lifting drive mechanism 232 that drives the limiting bowl 231 to move vertically (for example, the limiting bowl 231 is mounted on a bowl support plate 233, and the bowl lifting drive mechanism 232 is an electric cylinder or linear motor that extends downward along the output axis and is connected to the bowl support plate 233 and is fixed to the frame 10), a column pressing block 234 that can be inserted into the limiting bowl 231 from the top and is vertically slidably connected to the inside of the limiting bowl 231, and a column pressing drive mechanism 235 that drives the column pressing block 234 to move vertically to press the dough in the limiting bowl 231 into a column shape (for example, an electric cylinder or linear motor that extends downward along the output axis and is fixed to the frame 10). The diameter of the annular sidewall of the limiting bowl 231 is smaller than the diameter of the dough, for example, 1 / 3 to 1 / 2 of the diameter of the dough.

[0038] Initially, the base plate 21 is located directly below the column pressing assembly 23. The limiting bowl 231 moves downward, its bottom closed by the base plate 21. The base plate 21 and the limiting bowl 231 enclose a mold cavity, with the column pressing block 234 positioned above it, away from the limiting bowl 231. A worker places the fermented dough into the limiting bowl 231 through the dough inlet 12. The column pressing drive mechanism 235 causes the column pressing block 234 to move downward and insert into the limiting bowl 231, pressing the dough in the limiting bowl 231 into a cylindrical shape. The bowl lifting drive mechanism 232 drives the limiting bowl 231 upward to move away from the dough, and the column pressing drive mechanism 235 drives the column pressing block 234 upward to move away from the dough and return to its original position. Because the outer surface of the dough has non-stick edible oil, a non-stick layer can also be provided on the inner surface of the limiting bowl 231 and the lower surface of the column pressing block 234 to facilitate demolding, leaving the cylindrical dough on the base plate 21. The base plate drive mechanism 24 drives the base plate 21 to move with the dough to below the pressing assembly 22, where the pressing assembly 22 presses the cylindrical dough into a flatbread, as described above. After the bracket 31 removes the flatbread from the base plate 21, the base plate drive mechanism 24 drives the base plate 21 to move to below the column pressing assembly 23 and resets it. The bowl lifting drive mechanism 232 drives the limiting bowl 231 to move downward and reset it, and the base plate 21 closes the bottom of the limiting bowl 231.

[0039] Preferably, the upper end of the annular sidewall of the limiting bowl 231 is integrally formed with a larger diameter feed opening, which makes it easier for workers to place the fermented dough into the limiting bowl 231.

[0040] like Figure 4 , Figure 5 and Figure 8 As shown, in another preferred embodiment of this utility model, both the dough forming device 20 and the baking oven 80 are provided with a pin mechanism 25. The pin mechanism 25 has a plurality of pins 251 that can synchronously extend and retract to lift the dough. The bracket 31 has a plurality of insert rods that can be inserted longitudinally (along the length direction of the frame 10) between the pins 251. Specifically, the pin mechanism 25 also includes a pin plate 252 arranged parallel to the base plate 21 below the base plate 21, and a pin plate driving mechanism for driving the pin plate 252 to move vertically (for example, the pin plate driving mechanism is mounted on a bracket fixed to the base plate 21, and is an electric cylinder or linear motor with an upwardly extending output axis arranged vertically). The plurality of pins 251 are fixed to the upper surface of the pin plate 252. The base plate 21 has a plurality of pin holes 211 corresponding to a plurality of pins 251. The pin plate drive mechanism drives the pin plate 252 to move upward, carrying the pins 251. The pins 251 extend through the pin holes 211 and lift the dough on the base plate 21. The pin plate drive mechanism drives the pin plate 252 to move downward, and the pins 251 move downward and retract into or below the pin holes 211. In normal condition, the pins 251 are inserted into the pin holes 211 and their upper ends are flush with the upper surface of the base plate 21 to close the pin holes 211.

[0041] After the dough is pressed into a flatbread by the dough forming device 20, when the flatbread needs to be removed from the base plate 21 of the dough forming device 20, the flatbread is lifted by the ejector pins 251 of the ejector pin mechanism 25. The insert rod of the bracket 31 can be inserted between the ejector pins 251 and located below the flatbread. By retracting the ejector pins 251 of the ejector pin mechanism 25, the flatbread can fall onto the bracket 31, and the bracket 31 removes the flatbread from the base plate 21. When the sauce spreading device 40 spreads sauce and the food spreading device spreads food, the linear drive mechanism drives the bracket 31 to carry the flatbread to the corresponding work position. The flatbread is then spread with sauce and food on the bracket 31. When the dough on the tray 31 needs to be placed in the oven 80 for baking, the tray 31 carries the dough to the top of the ejector mechanism 25 of the oven 80. The ejector pins 251 of the ejector mechanism 25 extend and pass through the inserts of the tray 31 to lift the dough. The inserts of the tray 31 then exit from the gap between the extended ejector pins 251 and leave the oven 80. The ejector pins 251 in the oven 80 retract downwards, and the dough falls onto the baking tray 81 of the oven 80.

[0042] It should be noted that the connection between the ejector pin mechanism 25 in the baking oven 80 and the baking tray 81 is the same as the connection between the base plate 21 and the ejector pin mechanism 25, and will not be described in detail here. The pin plate drive mechanism that drives the ejector pin 251 in the baking oven 80 is located outside the baking oven 80 at the bottom. The output shaft of the pin plate drive mechanism is sealed to the baking oven 80. The sealing method is existing technology and will not be described in detail here.

[0043] In one embodiment of this utility model, the bracket 31 is inserted between the pins 251 of the dough forming device 20 to remove the dough from the base plate 21, and the bracket 31 is inserted between the pins 251 of the baking oven 80 to send the dough into the baking oven 80. Both actions can be accomplished by driving the bracket 31 to move by the linear drive mechanism. At this time, the stroke of the linear movement of the frame slide rail 32 and the bracket 31 should be able to cover the linear movement range of the bracket 31.

[0044] like Figure 4 and Figure 5 As shown, in another preferred embodiment, the bracket 31 is also connected to a bracket rotation drive mechanism 35 that drives its horizontal rotation. The bracket rotation drive mechanism 35 is a rotary motor mounted on the bracket slide plate 33. The output axis of the rotary motor extends upward and is fixedly connected to the mounting plate 311 supporting the bracket 31. Specifically, when it is necessary to remove the dough from the base plate 21 of the dough forming device 20, the bracket rotation drive mechanism 35 drives the bracket 31 to rotate horizontally, so that the insert of the bracket 31 faces the dough forming device 20, and the insert is inserted between the ejector pins 251 on the base plate 21 to remove the dough. Figure 8As shown, when the dough on the bracket 31 at the vegetable filling station 17 needs to be placed in the baking oven 80 for baking, the bracket rotation drive mechanism 35 drives the bracket 31 to rotate horizontally by 180°, so that the insert of the bracket 31 faces the baking oven 80, and the insert of the bracket 31 is inserted longitudinally between the ejector pins 251 in the baking oven 80 to place the dough, and the dough falls on the ejector pins 251.

[0045] The instruction manual states that, depending on the actual situation, after the linear drive mechanism drives the tray 31 to carry the dough to the cheese topping station 15 to spread the cheese, the rotating drive mechanism 35 drives the tray 31 to rotate horizontally by 180°, so that the subsequent spreading of ingredients is carried out on the tray 31 that has rotated 180°.

[0046] like Figure 4 As shown, in this utility model, the sauce application device 40 includes a sauce tank 41 mounted on the frame 10, a sauce brush 42 with a sauce outlet connected to the sauce tank 41 via a conveying pipe, and a sauce delivery pump (not shown in the figure) that conveys the sauce in the sauce tank 41 to the sauce brush 42 via the conveying pipe. The method of conveying the sauce in the sauce tank 41 to the sauce brush 42 via the sauce delivery pump is prior art and will not be described in detail here. The sauce brush 42 is connected to a brush lifting drive mechanism 43 that drives its vertical movement to approach or move away from the dough at the sauce brushing station 14, and a brush lateral drive mechanism (not shown in the figure) that drives it to move along a direction perpendicular to the dough feeding direction. For example, a brush slide rail 44 is fixed to the frame 10, and a brush slider 45 is slidably connected to the brush slide rail 44 laterally (along the width direction of the frame 10). The brush lateral drive mechanism is an electric cylinder or linear motor whose output shaft extends laterally and is connected to the brush slider 45 to drive its lateral movement. The brush lifting drive mechanism 43 is an electric cylinder or linear motor whose output shaft extends downward and is mounted on the brush slider 45. The end of the brush lifting drive mechanism 43 is connected to the sauce brush 42. The brush lifting drive mechanism 43 drives the sauce brush 42 to move vertically to approach or move away from the dough surface, and the brush lateral drive mechanism causes the brush slider 45 to carry the brush lifting drive mechanism 43 laterally, so that the sauce brush 42 moves laterally to brush sauce on the dough surface.

[0047] The tray 31 of the conveying device 30 carries the dough in a longitudinal (length direction of the frame 10, such as the Y-axis) feeding motion, and the brush transverse drive mechanism drives the sauce brush 42 to move laterally (width direction of the frame 10, such as the X-axis). Through the movement in the X and Y directions, the sauce is evenly brushed onto the entire upper surface of the dough.

[0048] like Figure 1As shown, in this utility model, multiple food spreading devices include a cheese spreading device 50, a meat spreading device 60, and a vegetable spreading device 70. The tray 31 of the conveying device 30 can carry the dough to the cheese spreading station 15, the meat spreading station 16, and the vegetable spreading station 17 in sequence. The cheese spreading device 50, the meat spreading device 60, and the vegetable spreading device 70 can spread their respective ingredients onto the dough at the corresponding spreading station.

[0049] like Figure 1 As shown, the cheese spreading device 50 spreads diced cheese or cheese strips, and the vegetable spreading device 70 spreads diced vegetables. For example, two vegetable spreading devices 70 are set along the length of the frame 10 to spread diced green peppers and diced onions respectively (the specific ingredients can be changed according to the taste of the pizza). The cheese spreading device 50 and the vegetable spreading device 70 are located on the same side of the frame 10.

[0050] like Figure 4 and Figure 5 As shown, in this invention, the cheese spreading device 50 includes a container 51 for holding ingredients, a spreading cover 52 for spreading the ingredients, and an ingredient conveying mechanism 53 connected to the container 51 and the spreading cover 52 for conveying the ingredients from the container 51 to the spreading cover 52. The size of the spreading cover 52 is adapted to the size of the dough, and the spreading cover 52 is located directly above and close to the dough, spreading the ingredients on the surface of the dough. The structure of the vegetable spreading device 70 is the same as that of the cheese spreading device 50, and will not be described again.

[0051] Specifically, the food conveying mechanism 53 is a horizontally arranged spiral conveyor. The motor 532 of the spiral conveyor 53 rotates its spiral blades 531 to convey the food from the material container 51 to the spreading cover 52. Using a spiral conveyor 53 to convey materials is not existing technology and will not be described in detail here. A material cylinder 54 is connected to the upper end of the spreading cover 52. The food conveyed by the spiral conveyor 53 enters the spreading cover 52 through the material cylinder 54. A spreading frame 521 is provided inside the spreading cover 52. The spreading frame 521 has multiple downwardly extending material rods arranged circumferentially. The spreading frame 521 is connected to a spreading drive mechanism 522 that drives its rotation to evenly spread the food on the dough (for example, the spreading drive mechanism 522 is a rotary motor with its output shaft extending downwards from the top of the material cylinder 54 into the spreading cover 52). Using a cheese spreading device 50 and a vegetable spreading device 70 to spread the food is existing technology and will not be described in detail here.

[0052] like Figure 1 and Figure 9As shown, the meat spreading device 60 spreads meat slices, and is located on the opposite side of the cheese spreading device 50 and the vegetable spreading device 70. The meat spreading device 60 includes a slicer 61 for slicing meat chunks, a meat slice tray 62 for placing meat slices, a meat slice conveyor belt 63 (preferably the meat slice conveyor belt 63 extends along the length of the frame 10 for a more compact structure) connected to the slicer 61 and the meat slice tray 62, a suction cup assembly 64 for picking up meat slices from the meat slice tray 62, and a suction cup drive mechanism 65 for driving the suction cup assembly 64 to move and transport the meat slices to the meat spreading station 16.

[0053] like Figure 9 As shown, specifically, the suction cup drive mechanism 65 includes a laterally extending horizontal column 651 fixedly connected to the frame 10. A suction cup slider 652 is laterally slidably connected to the horizontal column 651. A suction cup lateral drive mechanism 654 (e.g., an electric cylinder or linear motor with a laterally extending output shaft) connected to the suction cup slider 652 is mounted on the horizontal column 651 to drive its lateral movement. A suction cup lifting drive mechanism 653 (e.g., an electric cylinder or linear motor with a downward extending output shaft) is mounted on the suction cup slider 652. The end of the suction cup lifting drive mechanism 653 is connected to the suction cup assembly 64. The suction cup lifting drive mechanism 653 drives the suction cup assembly 64 to move vertically to pick up and put down meat slices. The suction cup lateral drive mechanism 654 causes the suction cup assembly 64 to move laterally by causing the suction cup slider 652 to carry the suction cup lifting drive mechanism 653 to move laterally.

[0054] In this invention, the slicer 61 can be a meat slicer that can automatically slice meat in the prior art or the structure provided below in this application. The sliced ​​meat pieces fall onto the meat slice conveyor belt 63, where they are laid flat and conveyed by the belt. The conveyor belt 63 has baffles on both sides to prevent the meat pieces from slipping. The meat pieces move along the conveyor belt 63 to its end and fall onto the meat slice tray 62. The suction cup lifting drive mechanism 653 drives the suction cup assembly 64 downwards to contact the meat pieces in the meat slice tray 62. The suction cup assembly 64 picks up the meat slice tray 62 through negative pressure. After picking up the meat slices, the suction cup lifting drive mechanism 653 drives the suction cup assembly 64 upward to move away from the meat slice tray 62. The suction cup lateral drive mechanism 654 drives the suction cup assembly 64 carrying the meat slices to move to the meat spreading station 16. The suction cup assembly 64 is located directly above the dough at the meat spreading station 16. The suction cup lifting drive mechanism 653 drives the suction cup assembly 64 downward to move closer to the dough. The suction cup assembly 64 releases pressure, causing the meat slices on it to fall and spread on the dough. Afterward, the suction cup assembly 64 returns to its initial position.

[0055] like Figure 9As shown, in another preferred embodiment, the meat spreading device 60 further includes a disc rotation drive mechanism 621 that drives the meat slice disc 62 to rotate horizontally so that the meat slices output from the meat slice conveyor belt 63 are evenly spread on the meat slice disc 62, and a disc position drive mechanism 622 that drives the meat slice disc 62 to move back and forth between the lower end of the meat slice conveyor belt 63 and the lower part of the suction cup assembly 64. For example, a longitudinally extending disc slide rail 624 is fixedly connected to the disc support 623 connected to the frame 10, and a disc slider 625 is longitudinally slidably connected to the disc slide rail 624. The disc rotation drive mechanism 621 is a rotary motor mounted on the disc slider 625 that drives the meat slice disc 62 to rotate horizontally, and the disc position drive mechanism 622 is a linear motor or electric cylinder mounted on the disc support 623 that drives the disc slider 625 to move linearly longitudinally.

[0056] Initially, the meat slice tray 62 is located near the end of the meat slice conveyor belt 63, with only a portion of the outer end of the tray below the conveyor belt 63, and the rest outside the belt. The tray rotation drive mechanism 621 drives the meat slice tray 62 to rotate. As the tray rotates, the meat slices output from the conveyor belt 63 are evenly spread on it. Once the tray is full (the number of slices can be determined by time to confirm full coverage), the conveyor belt 63 stops. The tray position drive mechanism 622 then moves the tray 62 to directly below the suction cup assembly 64. After the suction cup assembly 64 picks up the meat slices from the tray 62, the tray position drive mechanism 622 moves the tray 62 back to the end of the conveyor belt 63 to reset it.

[0057] like Figure 9 As shown, in another preferred embodiment of this utility model, the slicer 61 includes a downwardly inclined meat block groove 611 extending along the length direction of the frame 10 for placing meat blocks, a pushing mechanism 612 for pushing the meat blocks in the meat block groove 611 to move obliquely downward, and a blade mechanism 613 for slicing the meat blocks. The pushing mechanism 612 can push a portion of the meat block to extend out of the outlet at the lower end of the meat block groove 611. By moving the meat block in the meat block groove 611 relative to the blade mechanism 613, the portion of the meat block extending outward is cut off (specifically, the meat block groove 611 can move, or the blade mechanism 613 can move to cut off the meat slices through relative movement, similar to slicing meat with a kitchen knife, which is prior art and will not be described in detail here). The cut meat slices fall onto the meat slice conveyor belt 63.

[0058] like Figure 9As shown, preferably, a plurality of meat slots 611 are arranged side by side on the support plate 614. The support plate 614 is connected to a slot drive mechanism 615, which drives the support plate 614 to move along the width direction of the meat slots 611 so that the outlets of the plurality of meat slots 611 can intermittently correspond to the blade mechanism 613. The slot drive mechanism 615 can be a linear motor or electric cylinder with its output shaft extending laterally, mounted on a mounting block 616 connected to the frame 10. Preferably, a transversely colored slot slide rail 617 is fixedly connected to the mounting block 616, and the bottom plate of the support plate 614 is provided with a slot slider that is slidably connected to the slot slide rail 617. The slot drive mechanism 615 drives the support plate 614 to slide on the slot slide rail 617 via the slot slider.

[0059] Figure 9 The diagram shows three meat slots 611, which can be used to hold different meats such as bacon, sausage, and ham, allowing for the creation of pizzas with different meat flavors. For example, for sausage pizza, the slot drive mechanism 615 moves the support plate 614 laterally, precisely positioning the corresponding sausage meat slot 611 at the blade mechanism 613. This design enables rapid switching between various meats, meeting the customized needs of different flavored pizzas and enhancing product diversity.

[0060] like Figure 2 As shown, in another preferred embodiment, the pizza-making machine further includes a control cabinet 90, which is located at one corner of the rectangular pizza-making machine. The housing of the control cabinet 90 is fixed to the outer shell 11. The enable terminals of the dough forming device 20, conveying device 30, sauce spreading device 40, cheese spreading device 50, meat spreading device 60, vegetable spreading device 70, and baking oven 80 are connected to the control terminal of the control cabinet 90. The control cabinet 90 controls the operation of each device, and the operation of each device can be carried out according to the preset program in the control cabinet 90. This is prior art and will not be described in detail here.
