Description

Technical Field

[0001] This invention relates to the field of pizza making equipment technology, and in particular to a pizza forming machine. Background Technology

[0002] Pizza is a food originating in Italy. It's typically made by topping a round, leavened dough with tomato sauce, cheese, and other ingredients, then baking it in an oven. The preparation of the pizza dough is crucial, as its texture determines the overall taste of the pizza. Currently, pizza dough is made by hand, kneading and pressing it into shape. This method is time-consuming, labor-intensive, and inefficient, making it difficult to guarantee the quality and hygiene of the pizza dough.

[0003] Existing pizza dough making equipment typically uses two pressure plates to press the dough together. However, this type of equipment has the following drawbacks: 1. After the dough is pressed by the rigid pressure plates, it often sticks to the plates and is difficult to detach; 2. The rigid pressure plates easily damage the dough and merely flatten it, making it difficult to form a relatively uniform round dough; 3. Pizza dough comes in various thicknesses, depending on the dough ratio and cost, often requiring different thicknesses. Existing pizza dough making equipment struggles to effectively adjust the thickness of the formed dough. Therefore, further improvements are needed. Summary of the Invention

[0009] Optionally, the rotation limit block is an eccentric wheel or a cam structure; the lower platform is provided with an adjustment shaft for rotating the rotation limit block; rotating the rotation limit block changes the contact point between the outer contour of the rotation limit block and the upper swing arm, thereby changing the rotation angle when the upper swing arm abuts against the rotation limit block, which is used to change the position of the middle pull rod when the lower platform is raised to the top position, and thus adjust the distance between the roller assembly and the lower support plate.

[0010] Optionally, the outer side of the lower platform is provided with an adjustment knob connected to the adjustment shaft.

[0011] Optionally, the two ends of the intermediate tie rod are provided with adjusting hinge seats; the adjusting hinge seats are threadedly connected to the ends of the intermediate tie rod; rotating the intermediate tie rod can change the relative position of the two adjusting hinge seats and the intermediate tie rod, so as to lengthen or shorten the relative distance between the two adjusting hinge seats, thereby changing the length and position of the intermediate tie rod when the lower platform is raised to the top position, and thus adjusting the distance between the roller assembly and the lower support plate.

[0012] Optionally, a force-applying platform is provided in the middle of the intermediate tie rod; the outer contour of the force-applying platform has a regular hexagonal shape.

[0016] The beneficial effects of this invention are: 1.

This rolling and pressing process is gentle and uniform, which can naturally stretch the dough into a round shape, effectively avoiding the problems that may be caused by rigid pressing, such as damage to the internal gluten network of the dough, hardening of the texture, or cracking of the edges. This results in a round pizza dough with a uniform texture and regular edges.

[0017] 2. Basic Adjustable Thickness of Dough: The lifting component adopts a hand-cranked lifting structure. By rotating the hand crank, the lower platform and lower support plate are raised and lowered through the linkage structure, thereby adjusting the distance between the lower support plate and the roller assembly. The size of the distance directly corresponds to the thickness of the formed dough.

[0019] 4. Extremely effortless operation and excellent user experience: This component actively provides upward lifting force to balance the gravitational load of the lower platform, dough, and some mechanisms, significantly reducing the force required for the operator to crank the joystick.

[0027] Example Reference Figure 1 and Figure 2 The present invention discloses a pizza forming machine, comprising a housing 10, an upper platform 20, a lower platform 30, a lifting assembly 40, an upper drive assembly 50, a roller assembly 60, and a control center. The upper platform 20 and the lower platform 30 are located on the upper and lower sides of the chassis 10; the upper platform 20 is provided with an upper rotating disk 21, and several roller assemblies 60 are provided on the lower side of the upper rotating disk 21; the upper drive assembly 50 is used to drive the upper rotating disk 21 to rotate. The lower platform 30 is provided with a lower support plate 31; the lifting assembly 40 includes a hand-cranked lifting structure, including a hand crank 41 and a support rod assembly; the support rod assembly includes several hinged connecting rod structures; by rotating the hand crank 41, the lower platform 30 and the lower support plate 31 can be raised through several connecting rods, and the lower support plate 31 can be brought closer to the roller assembly 60 of the upper rotating plate 21; The chassis 10 is provided with an auxiliary upper support assembly 70; the auxiliary upper support assembly 70 is used to lift the lower platform 30 upwards to reduce the torque required to rotate the hand crank 41.

[0028] The beneficial effects of this invention are: 1. High-quality forming without damaging the dough structure: The upper rotating disc 21 drives multiple rolling components 60 to roll and press the dough, replacing the traditional method of direct pressing with a rigid pressing plate. This rolling and pressing process is gentle and uniform, which can naturally stretch the dough into a circle, effectively avoiding the problems that may be caused by rigid pressing, such as damage to the internal gluten network of the dough, hardening of the texture, or cracking of the edges, thus obtaining a round pizza dough with uniform texture and regular edges.

[0029] 2. Basic Adjustable Thickness of Dough: The lifting component 40 adopts a hand-cranked lifting structure. By rotating the hand crank 41, the lower platform 30 and the lower support plate 31 are raised and lowered using the linkage structure, thereby adjusting the distance between the lower support plate 31 and the roller assembly 60. The size of the distance directly corresponds to the thickness of the formed dough. The operation is simple and convenient, and the basic thickness can be adjusted without disassembling the equipment. It is suitable for making dough with different ratios and different cost requirements, solving the defect of inconvenient thickness adjustment in existing equipment.

[0030] 3. Stable structure and convenient operation: The overall structure is reasonably laid out, with the upper platform 20 and the lower platform 30 set in correspondence. The roller assembly 60 is precisely matched with the rotating disk and support disk. The hand-cranked lifting structure is easy to operate. The control center can realize the start and stop of the upper drive assembly 50, speed adjustment, etc., which is suitable for operators with different skill levels and lowers the operation threshold.

[0031] 4. Extremely labor-saving operation and excellent user experience: This component can actively provide an upward lifting force to balance the gravitational load of the lower platform 30, the dough, and some mechanisms, greatly reducing the force required for the operator to crank the hand lever 41. This makes the equipment easy and quick to operate, reducing labor intensity.

[0032] In this embodiment, the support rod assembly includes an upper swing arm 42, a middle tie rod 43, and a lower swing arm 44; a handle connecting seat 11 is provided at the bottom of the chassis 10; the upper swing arm 42 is hinged to the lower platform 30, the lower swing arm 44 is hinged to the handle connecting seat 11, and the upper and lower ends of the middle tie rod 43 are respectively hinged to the upper swing arm 42 and the lower swing arm 44; a hand crank 41 passes through the handle connecting seat 11 and is connected to the lower swing arm 44; the hand crank 41 can rotate the lower swing arm 44 relative to the handle connecting seat 11 and move the middle tie rod 43 and the upper swing arm 42 upward to lift the lower platform 30. The upper swing arm 42, the middle pull rod 43, and the lower swing arm 44 are hinged together to form a stable linkage transmission structure. When the hand crank 41 is turned, the lower swing arm 44 rotates around the handle connecting seat 11, and drives the upper swing arm 42 to rotate synchronously through the middle pull rod 43, thereby smoothly lifting the lower platform 30. Compared with the traditional single pull rod lifting method, the linkage structure can prevent the lower platform 30 from tilting or swaying during the lifting process, ensuring that the distance between the lower support plate 31 and the roller assembly 60 is uniform, thereby ensuring that the thickness of the dough is consistent and avoiding the dough being too thin or too thick in some areas due to platform tilt. In this embodiment, the lower platform 30 is provided with a platform fixing shaft 32; the middle part of the upper swing arm 42 is rotatably connected to the platform fixing shaft 32; a rotation limiting block 33 is provided on one side of the platform fixing shaft 32; the upper end of the middle pull rod 43 is hinged to the end of the upper swing arm 42 away from the rotation limiting block 33; when the middle pull rod 43 moves upward, it can push the upper swing arm 42 to rotate and abut against the rotation limiting block 33; the rotation limiting block 33 restricts the rotation angle of the upper swing arm 42, so that the middle pull rod 43 can only push the upper swing arm 42 upward, so that the lower platform 30 can be raised. The upper swing arm 42 is rotatably connected to the platform fixed shaft 32 in the middle. The platform fixed shaft 32 provides a stable rotation fulcrum for the upper swing arm 42, so that the upper swing arm 42 will not deviate or sway during rotation, thereby ensuring the smoothness of the lower platform 30's lifting and lowering. This prevents the lower support plate 31 from tilting due to the upper swing arm 42's deviation, ensuring that the dough forming thickness is uniform. The rotation limit block 33 is set on one side of the platform fixed shaft 32. The upper end of the middle pull rod 43 is hinged to the end of the upper swing arm 42 away from the rotation limit block 33. When the middle pull rod 43 moves upward to push the upper swing arm 42 to rotate, the upper swing arm 42 will eventually abut against the rotation limit block 33. The rotation limit block 33 can effectively limit the maximum rotation angle of the upper swing arm 42, thereby limiting the highest lifting position of the lower platform 30. This prevents the lower platform 30 from being lifted too high, causing excessive compression between the roller assembly 60 and the lower support plate 31, which could damage the dough or equipment components.

[0033] Specifically, the rotation limit block 33 is an eccentric wheel or cam structure; the lower platform 30 is provided with an adjustment shaft 34 for rotating the rotation limit block 33; rotating the rotation limit block 33 changes the contact point between the outer contour of the rotation limit block 33 and the upper swing arm 42, thereby changing the rotation angle when the upper swing arm 42 abuts against the rotation limit block 33, which is used to change the position of the middle pull rod 43 when the lower platform 30 is raised to the top position, thereby adjusting the distance between the roller assembly 60 and the lower support plate 31. The outer contour of the eccentric wheel or cam structure is non-circular. When the rotating limit block 33 is rotated, the contact point between its outer contour and the upper swing arm 42 will change, thereby changing the rotation angle when the upper swing arm 42 and the rotating limit block 33 are in contact. The change in rotation angle will change the position of the middle pull rod 43 when the lower platform 30 is raised to the top position, and finally adjust the distance between the roller assembly 60 and the lower support plate 31, so as to achieve fine adjustment of the dough thickness. Compared with the traditional fixed limit structure, the thickness can be flexibly adjusted according to actual needs to adapt to the production of pizza dough of different thicknesses.

[0034] Furthermore, an adjustment knob 35 connected to the adjustment shaft 34 is provided on the outer side of the lower platform 30. The adjustment knob 35 is located on the outer side of the lower platform 30, in a position that is easy for the operator to access and observe. During the adjustment process, the change in the distance between the roller assembly 60 and the lower support plate 31 can be observed simultaneously, which facilitates timely adjustment and avoids over-adjustment or under-adjustment, thereby improving the convenience and accuracy of operation.

[0035] In this embodiment, the two ends of the intermediate pull rod 43 are provided with adjusting hinge seats 45; the adjusting hinge seats 45 are threadedly connected to the ends of the intermediate pull rod 43; rotating the intermediate pull rod 43 can change the relative position of the two adjusting hinge seats 45 and the intermediate pull rod 43, so as to lengthen or shorten the relative distance between the two adjusting hinge seats 45, which is used to change the length and position of the intermediate pull rod 43 when the lower platform 30 is raised to the top position, thereby adjusting the distance between the roller assembly 60 and the lower support plate 31. By rotating the intermediate tie rod 43, the relative positions of the two adjusting hinge seats 45 and the intermediate tie rod 43 can be changed through the transmission action of the threaded connection, thereby lengthening or shortening the relative distance between the two adjusting hinge seats 45. This change in distance will change the length and position of the intermediate tie rod 43 when the lower platform 30 is raised to the top position. Thus, the distance between the roller assembly 60 and the lower support plate 31 can be compensated by the adjustment of the eccentric wheel / cam structure, achieving coarse-precision thickness adjustment and dual thickness adjustment, further improving the adjustment flexibility and accuracy.

[0036] Furthermore, a force-applying platform 431 is provided in the middle of the intermediate pull rod 43; the outer contour of the force-applying platform 431 is a regular hexagonal structure. Designing the force-applying platform 431 in the middle of the intermediate pull rod 43 as a regular hexagon makes it easier to use standard wrenches and other tools for rotational adjustment, making the length adjustment operation more labor-saving and precise.

[0037] In this embodiment, the chassis 10 is provided with an auxiliary upper support assembly 70; the auxiliary upper support assembly 70 is used to lift the upper swing arm 42 upwards to reduce the torque required to rotate the hand crank 41. The addition of the auxiliary upper support assembly 70 provides upward assistance, partially offsetting the weight of the lower platform 30 and the dough, significantly reducing the force required to crank the hand crank 41, making the equipment easier to operate, especially suitable for situations requiring frequent adjustments or carrying large dough balls; the auxiliary upper support assembly 70 can share the weight of the lower platform 30 and lower support plate 31 borne by the connecting rod structure, reducing the stress on each hinge point, preventing the connecting rod from bending and the hinge points from wearing out too quickly due to excessive long-term stress, thereby protecting the connecting rod structure, extending the service life of the equipment, and reducing maintenance costs.

[0038] Specifically, the auxiliary lifting assembly 70 includes a weight block 71, an upper pulley 72, a lower pulley 73, and a steel wire cable 74; the end of the upper swing arm 42 is provided with a hook 421; the upper pulley 72 is located on the upper part of the housing 10, and the lower pulley 73 is located on the side of the lower platform 30; one end of the steel wire cable 74 is fixed to the hook 421, passes over the lower pulley 73 and the upper pulley 72, and the other end is fixed to the weight block 71. The steel wire cable 74 passes over the upper pulley 72 and the lower pulley 73, with one end connected to the hook 421 of the upper swing arm 42 and the other end connected to the weight block 71. The weight of the weight block 71 generates a downward pulling force, which is converted into an upward lifting force on the swing arm through the transmission action of the pulley system. The magnitude of the lifting force can be controlled by adjusting the weight of the weight block 71 to adapt to different load requirements, ensuring a stable and reliable auxiliary lifting effect. All components are standardized, with a simple structure and low failure rate. The wire cable 74 can be easily disassembled and replaced, and the weight block 71 can be flexibly increased or decreased according to needs. During later maintenance, there is no need to disassemble the entire equipment; only the worn wire cable 74 or pulley components need to be replaced, resulting in low maintenance costs and high maintenance efficiency. The layout of the pulley block and wire cable 74 is reasonable, without occupying the operating space of the equipment or interfering with the normal operation of the hand crank 41, the lifting and lowering of the lower platform 30, etc. At the same time, the hook lug 421 ensures that the connection between the wire cable 74 and the upper swing arm 42 is firm, preventing it from falling off and improving the safety of equipment operation.

[0039] In this embodiment, a removable lower support cover 36 is provided on the lower support plate 31; the lower support cover 36 is detachably provided with a lower elastic anti-stick pad 37. The elastic pad provides excellent anti-stick performance, making the dough easy to remove; the removable structure greatly facilitates cleaning and maintenance after use, solves the problem of hygiene dead corners, and allows for the replacement of pads with different surface properties to adapt to special doughs.

[0040] Furthermore, the upper platform 20 is equipped with a detachable ground support cover 22; the middle of the upper support cover 22 has a through-hole structure; the upper support cover 22 is detachably equipped with an upper elastic anti-stick pad 23; the rolling assembly 60 abuts against the upper side of the upper elastic anti-stick pad 23. The detachable upper support cover 22 of the upper platform 20, with its through-hole structure in the middle, ensures that the rolling assembly 60 on the upper rotating plate 21 can pass smoothly and contact the dough on the lower support plate 31 to achieve rolling and shaping; the detachable upper elastic anti-stick pad 23 on the upper support cover 22, abutting against the upper side of the rolling assembly 60, can prevent dough fragments from sticking to the surface of the rolling assembly 60 during the rolling process, ensuring the cleanliness and smooth rolling of the rolling assembly 60, thereby ensuring a uniform rolling effect. Meanwhile, the detachable design makes the upper support cover 22 and the upper elastic anti-stick pad 23 easy to remove, clean, and replace. Together with the lower elastic anti-stick pad 37, this further enhances the hygiene, safety, and ease of maintenance of the equipment. The elastic material also helps to cushion the impact, reducing the hard impact of the roller assembly 60 on the dough and protecting its texture. The upper support cover 22 and its upper elastic anti-stick pad 23 form a coordinated anti-stick system. This ensures that even if a small amount of dough rubs against the roller during the rolling process, it will not stick to the upper mechanism. The through-hole structure also ensures smooth installation and operation of the upper rotating disc 21 and the roller assembly 60. The detachable design also facilitates cleaning.

[0041] In this embodiment, the anti-stick pad can be made of food-grade TPU (thermoplastic polyurethane) or food-grade silicone material.

[0042] In this embodiment, the housing 10 is provided with a longitudinal guide rod 12, which passes through the lower platform 30. A linear bearing and / or bushing are provided between the longitudinal guide rod 12 and the lower platform 30. The longitudinal guide rod 12, in conjunction with the linear bearing or bushing, provides precise vertical guidance and a low-friction movement path for the lifting and lowering movement of the entire lower platform 30. This overcomes any lateral forces or gaps that may exist in the lifting assembly, ensuring that the lower platform 30 lifts and lowers smoothly and steadily, thereby guaranteeing the consistency of each molding action and extending the service life of the lifting assembly 40.

[0043] In this embodiment, the upper drive assembly 50 includes a drive motor, a timing belt, and a timing pulley. The drive motor is electrically connected to the control center and rotates the upper rotating disk 21 via the timing belt and timing pulley.

[0044] The operation process of the pizza forming machine of the present invention: Preparation stage: Based on the required thickness of the pizza dough, pre-set the highest lifting position of the lower platform (i.e., the minimum gap between the roller and the anti-stick pad of the lower support plate) by rotating the adjustment knob on the outside of the machine box (changing the angle of the eccentric wheel) or by using a tool to rotate the middle pull rod (changing its length).

[0045] Place the dough: Place the fermented dough ball in the center of the removable non-stick pad on the lower support plate.

[0046] Rolling and Shaping: Start the equipment. The upper drive assembly drives the upper rotating disc to begin rotating at a constant speed. The operator slowly cranks the hand crank, using the linkage mechanism to smoothly lift the lower platform along with the dough on it upwards. When the dough contacts the rotating roller assembly above, the roller, driven by the rotating upper disc, rolls and flattens the dough. As the lower platform continues to rise, the dough gradually expands outwards under the continuous and uniform rolling pressure of multiple rollers, being rolled into a round disc of uniform thickness. Elastic non-stick pads effectively prevent the dough from sticking to the upper and lower metal components.

[0047] Thickness control: When the platform rises to the preset highest position limited by the rotation limit block (eccentric wheel), stop cranking the hand crank. At this point, the dough is exactly crushed to the preset thickness. Throughout the crushing process, the load-bearing block of the auxiliary upper support component applies an auxiliary lifting force to the upper swing arm through steel cables and pulleys, making it very easy to crank the hand crank.

[0048] Removing the dough: After rolling, the control center can be set to rotate the upper turntable for a few more seconds to make the dough shape more uniform, then stop rotating. Slowly crank the hand crank in the opposite direction to lower the lower platform back to its original position. Due to the anti-stick pad, the shaped dough will naturally remain on the lower support cover and can be easily removed for further processing.

[0049] Cleaning and maintenance: After use, the upper and lower support covers along with the anti-stick pads can be removed for cleaning, which is convenient and hygienic.

[0050] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
