Description

Technical Field

[0001] This invention relates to the field of cake making, and in particular to an integrated device and operating method for intelligent mold switching and automatic forming of multi-flavor layered cakes. Background Technology

[0002] With the continuous development of the food processing industry, consumers have placed higher demands on the diversity of cake flavors, the layering of shapes, and the stability of quality. Multi-layered cakes, due to their rich taste experience, have gradually become one of the mainstream products in the market. However, the production process of multi-layered cakes still faces many technical bottlenecks. Existing production methods are unable to balance production efficiency, product quality, and automation, and cannot meet the needs of large-scale, standardized industrial production.

[0003] Currently, the production of multi-layered cakes mainly relies on manual operation or semi-automated equipment. In the manual production mode, operators need to manually perform processes such as mold assembly, flavor filling, baking and transfer, and demolding. This is not only labor-intensive and inefficient, but also prone to uneven thickness of each layer and blurred flavor boundaries due to human error.

[0004] To address the shortcomings of manual production, some companies have adopted semi-automated production equipment. However, the mold switching and assembly of existing semi-automated equipment mostly rely on manual assistance for positioning, and the connection structure between molds is mostly traditional snap-fit ​​or bolt connection, which is not only cumbersome to disassemble and assemble, but also cannot achieve automated disassembly and assembly.

[0005] To address the aforementioned issues, the industry urgently needs an integrated device capable of intelligent switching, automatic assembly, precise batter injection, and efficient demolding of multi-flavor layered cake molds, in order to meet the high-efficiency, stable, and safe requirements for multi-flavor layered cake production in large-scale food processing scenarios. Summary of the Invention

[0006] To address the shortcomings mentioned above in the background technology, the present invention provides an integrated device and operating method for intelligent mold switching and automatic forming of multi-flavor layered cakes.

[0007] The present invention adopts the following technical solution: A multi-flavor layered cake intelligent mold switching and automatic forming integrated device, characterized in that it includes: The frame is equipped with a workbench and a liftable grouting pipe; The mold includes a mold body and a bottom plate. The mold body has a through hole and a bottom plate at its bottom end. The bottom plate is composed of multiple sub-bottom plates. The sub-bottom plates can move horizontally relative to the mold body to cut off or open the through hole. The inner and outer surfaces of the mold body are provided with clearance openings to allow the sub-bottom plates to move. The driving mechanism, located within the cavity of the mold body, includes a first gear, a second gear, a third gear, a fourth gear, a fifth gear, and a mounting strip. The first gear is an internal gear, located within the cavity and meshing with the second gear. The second gear and the third gear are coaxially arranged. The third gear is fixed within the cavity. The shaft of the second gear passes through the third gear and is fixedly connected to the mounting strip. The third gear meshes with the fifth gear via the fourth gear. Both the fourth gear and the fifth gear are mounted on the mounting strip, and the shaft of the fifth gear is fixedly connected to the dividing plate. The fixture includes a fixture body and a clamping part. The fixture body is movable relative to the frame. The fixture body has an opening for inserting the mold body. Retractable clamping parts are provided on both sides of the opening for clamping the mold body. The lifting section includes a lifting rod and a lifting tray located at the top of the lifting rod. The lifting tray is located below the workbench and is used to lift and eject the cake during demolding. Multiple empty molds are placed on the platform of the machine frame. One of the molds is moved to the worktable by a movable clamp. At this time, the bottom plate inside the mold closes and cuts off the through hole. Cake batter is poured in through the injection pipe. Then, another mold is clamped and moved to the mold that has been filled with batter and stacked together. Another flavor of cake batter is poured in. Then, the combined mold and the poured cake batter are baked and cooled. When demolding, the bottom plate is first opened by the drive mechanism. At this time, the through hole inside the combined mold is connected. The cake is pushed out of the combined mold by the rising lifting tray, and the demolding is completed.

[0008] As a further improvement, the drive mechanism also includes a worm gear and a worm shaft that mesh with each other. The worm gear is coaxially arranged with the first gear and rotates synchronously, and the worm shaft extends out of the surface of the mold body.

[0009] As a further improvement, the worm gear is driven by a rotating tool on the frame, the two being detachably connected, and the rotating tool is movable relative to the frame.

[0010] As a further improvement, the rotating tool is an electric screwdriver, and the end of the worm shaft is hexagonal, which is adapted to the internal hexagonal hole of the electric screwdriver.

[0011] As a further improvement, the fixture is driven to move via a lead screw mechanism on the frame.

[0012] As a further improvement, one side of the workbench is provided with a clamp for holding the combined mold.

[0013] As a further improvement, the grouting pipe is lifted and lowered by a cylinder on the frame.

[0014] A method for an integrated device for intelligent mold switching and automatic forming of multi-flavor layered cakes, characterized by the following steps: Mold preparation: Place multiple empty molds of the same specifications neatly on the mold storage platform of the machine frame, ensuring that the bottom plates of each mold are in a closed state and the through holes are sealed; First injection: The clamp takes and holds one of the empty molds and moves it to the worktable; then, the injection pipe descends to the top opening of the mold and pours the first flavor of cake batter into the mold. After the injection is completed, the injection pipe rises back to its original position. Mold assembly and second layer pouring: The clamp moves again to grab another empty mold and moves it directly above the mold that has been filled with the first flavor of cake batter to stack and assemble it; then, the pouring pipe descends again to pour the second flavor of cake batter into the newly assembled mold above, completing the second layer pouring. If you need to make multi-layer, multi-flavor cakes, you can repeat the above mold assembly and pouring steps until all flavors are poured in layers. Baking and Cooling: After all layers of batter are poured, the assembled mold is moved to the preset baking area for high-temperature baking; after baking, the assembled mold is transferred to the cooling area for natural or forced cooling to room temperature to ensure the cake's shape is stable. Demolding and Recycling: After cooling, the combined mold is transferred back to the worktable; the first gear is rotated, and through the linkage of the second, third, fourth, and fifth gears and the mounting strip, the bottom pieces are driven to rotate and move outward along the clearance opening until all the bottom pieces are fully unfolded and the through holes of the combined mold are connected; finally, the lifting tray rises through the gap between the bottom pieces and enters the through hole, pushing the layered cake out of the combined mold as a whole, completing the demolding; after demolding, the lifting tray descends and resets, and the fixture transfers the empty mold to the recycling area to await subsequent cleaning, completing the entire production process.

[0015] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: Through the collaborative design of multiple components such as the frame, mold, drive mechanism, clamp, lifting part and supporting transmission components, it has the following core advantages: First, it realizes full-process automation of mold switching, grouting, splicing and demolding, greatly reducing manual intervention and improving production efficiency; Second, it adopts a precise screw drive and gear drive structure to ensure the positioning accuracy and motion stability of each component, and improve the uniformity of cake layering and molding quality; Third, the mold adopts a modular design, which is easy to disassemble, clean and replace, and adapts to the production needs of layered cakes of different sizes and flavors; Fourth, it integrates multiple protective structures such as worm gear self-locking, elastic sealing and anti-slip clamping, which improves the safety and reliability of the device operation and is suitable for large-scale and standardized food processing scenarios.

[0024] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] As attached Figure 1 , Figure 3 and Figure 8 As shown, a multi-flavor layered cake intelligent mold switching and automatic forming integrated device is provided. The device mainly includes a frame 1, a mold 2, a drive mechanism 3, a clamp 4, a lifting part 8 and a matching transmission component. All components work together to complete the entire process of cake layering, baking, cooling and demolding.

[0026] As attached Figure 1As shown, the frame 1, as the core load-bearing framework of the entire device, is integrally molded from high-strength aluminum alloy, possessing sufficient structural stability to withstand mechanical vibrations and component loads during production. It integrates key component mounting positions such as the workbench 11, the liftable grouting pipe 7, the cylinder 9, the rotating tool 6 mounting base, and the mold storage platform. Each mounting position is precision-machined to ensure coaxiality and positioning accuracy after component assembly. The workbench 11 is the core operating area for the mold 2, with a non-slip and wear-resistant surface treatment and clearance holes adapted to the lifting part 8, ensuring smooth demolding. The grouting pipe 7 is connected to the cylinder 9 via a guide rail on the top of the frame 1. The cylinder 9 adopts a double-acting design, driving the grouting pipe 7 to smoothly rise and fall vertically. The lifting stroke can be precisely controlled via a limit switch to meet the grouting needs of molds of different heights. The end of the grouting pipe 7 has a flow-controlled grouting port, allowing adjustment of the grouting speed according to the viscosity of the cake batter, preventing grout splashing or accumulation.

[0027] As attached Figures 2 to 6 As shown, mold 2 is crucial for achieving cake layering and flavor separation. Its structural design directly determines the layering accuracy and cake forming quality. It mainly consists of two parts: the mold body 21 and the base plate 23. The mold body 21 is made of food-grade stainless steel, possessing excellent high-temperature resistance and corrosion resistance, adaptable to subsequent baking process requirements. It has through-holes 22 running vertically through the interior, with the inner diameter precisely machined according to the target cake size. The inner walls are polished to reduce cake batter adhesion and facilitate subsequent demolding. The base plate 23 is mounted at the bottom of the mold body 21. This base plate 23 is composed of multiple identical sub-base plates 231 spliced ​​together. The sub-base plates 231 are made of lightweight food-grade alloy material, ensuring both structural strength and ease of movement. To enable flexible movement of the dividing plate 231, the inner and outer surfaces of the mold body 21 are provided with relief openings 211 that are adapted to the dividing plate 231. The size and guiding angle of the relief openings 211 are precisely calculated to ensure that the dividing plate 231 can move smoothly in the horizontal direction, so as to quickly cut off or open the through hole 22. When the dividing plate 231 is closed, it can completely block the through hole 22, providing a closed cavity for grouting; when the dividing plate 231 is unfolded, the through hole 22 is fully connected, providing a channel for demolding.

[0028] To achieve stable stacking of multiple molds 2, the top of the mold body 21 is integrally formed with an annular fixing groove 24, and the bottom is equipped with a fixing ring 25 that perfectly matches the size and shape of the fixing groove 24. Considering that the combined mold 2 needs to be moved to the baking and cooling areas to complete subsequent processes, a high-temperature pneumatic elastic locking connection structure is selected. This structure consists of a high-temperature resistant pneumatic telescopic locking pin (embedded in the inner side of the fixing groove 24, using ceramic seals and stainless steel locking pins that can withstand temperatures above 250°C), a locking hole (opened at the corresponding position of the fixing ring 25), and a built-in miniature high-temperature resistant gas tank. The gas tank is pre-filled with high-pressure gas, which can continuously provide driving force for the locking pin after the mold 2 moves. During assembly, the clamp 4 precisely aligns the upper mold 2 with the lower mold 2. After the fixing ring 25 is embedded in the fixing groove 24, the air tank drives the locking pin to extend and embed into the locking hole, achieving rapid locking. During disassembly, after the combined mold 2 returns to the preset position on the worktable 11, the pneumatic interface on the frame 1 moves and connects with the docking interface on the mold 2. Reverse air pressure is introduced to drive the locking pin to retract, completing automated unlocking. With the clamp 4, adjacent molds 2 can be efficiently disassembled. This structure ensures the coaxiality and sealing of adjacent molds 2 after assembly, preventing grout leakage during grouting. It also maintains stable locking throughout the baking and cooling process, while meeting the requirements for automated disassembly, facilitating the subsequent automated disassembly and recycling of molds 2. The movement of the pneumatic interface is consistent with the movement of the rotating tool 6. The inner wall of the fixing groove 24 is equipped with an elastic sealing gasket, which further improves the sealing performance after assembly and can also buffer the impact force during the assembly of molds 2, protecting the surface of molds 2 from damage.

[0029] As attached Figures 3 to 5 As shown, the drive mechanism 3 is built into the cavity of the mold body 21. It adopts a multi-gear linkage and worm gear transmission design, which can realize the precise and stable movement of the bottom piece 231. It mainly includes the first gear 31, the second gear 32, the third gear 33, the fourth gear 34, the fifth gear 35, the mounting strip 37, the worm gear 36, and the worm 38. The first gear 31 adopts an internal gear structure and is coaxially mounted on the inner wall of the cavity of the mold body 21, forming a meshing transmission with the second gear 32. The second gear 32 and the third gear 33 are coaxially arranged, but they are relatively independent. The third gear 33 is fixed in the cavity of the mold body 21 by a fixed bracket and remains stationary. The rotating shaft of the second gear 32 passes through the central hole of the third gear 33 and is fixedly connected to the mounting strip 37, so as to realize the synchronous rotation of the second gear 32 and the mounting strip 37. The third gear 33 forms a multi-stage meshing transmission through the fourth gear 34 and the fifth gear 35. The fourth gear 34 and the fifth gear 35 are both mounted on the mounting strip 37 by bearings and can rotate flexibly along their own axes. The end of the rotating shaft of the fifth gear 35 is fixed to the dividing plate 231 by a key connection, ensuring that the rotation of the fifth gear 35 can directly drive the rotation of the dividing plate 231.

[0030] To improve the transmission stability and power output accuracy of the drive mechanism 3, the mechanism is also equipped with a meshing worm gear 36 and worm 38. The worm gear 36 is coaxially and fixedly connected to the first gear 31 and can rotate synchronously with the first gear 31. The two ends of the shaft of the worm 38 are mounted to the side wall of the mold body 21 through bearings, and one end extends out of the outer surface of the mold body 21 as the power input end. The worm gear transmission structure has a self-locking function, which can effectively prevent the bottom sheet 231 from moving accidentally due to external force during grouting or baking, thereby improving the safety and reliability of the device operation.

[0031] As attached Figure 1 As shown, the rotating tool 6 provides power input to the drive mechanism 3, using an electric screwdriver as the core power component. It features adjustable speed and stable torque, adaptable to the movement needs of different sized die plates 231. To achieve precise docking between the rotating tool 6 and the worm gear 38, the end of the worm gear 38 extending from the surface of the mold body 21 is designed with a hexagonal structure, precisely matching the internal hexagonal chuck of the electric screwdriver. A detachable connection method facilitates docking of the rotating tool 6 with the worm gear 38 of different molds 2. The rotating tool 6 can move flexibly relative to the frame 1, driven by a lead screw mechanism 5 mounted on the frame 1. This lead screw mechanism 5 employs a two-axis drive design, with the base 51 positioned along the Z-axis (vertical direction) and Y-axis (horizontal forward / backward direction). Through the threaded transmission between the lead screw and the slider 52, the rotating tool 6 achieves precise positioning in the Z-axis and Y-axis directions, enabling rapid docking with the worm gear 38 of molds 2 at different positions, improving work efficiency.

[0032] As attached Figure 1 and Figure 7 As shown, the fixture 4 is mainly used for clamping, moving, and positioning the mold 2, and is the core component for realizing intelligent mold switching. It includes a fixture body 41 and a clamping part 43. The fixture body 41 adopts a rigid structure design, with a U-shaped opening 42 on one side that is adapted to the mold body 21. The size of the opening 42 is slightly larger than the outer diameter of the mold body 21 to ensure that the mold body 21 can be smoothly inserted. Retractable clamping parts 43 are symmetrically mounted on both sides of the opening 42. The clamping parts 43 adopt a cylinder-driven claw structure, and the inner side of the claw is provided with an anti-slip rubber pad, which not only ensures stable clamping of the mold body 21, but also avoids damage to the surface of the mold 2 during clamping. The extension stroke of the clamping part 43 can be precisely controlled by a sensor to adapt to the clamping requirements of molds 2 of different specifications.

[0033] The movement of the clamp 4 is driven by a lead screw mechanism 5 on the frame 1. This lead screw mechanism 5 adopts a three-axis drive design, enabling the clamp 4 to move flexibly in three dimensions: the X-axis (horizontal left-right direction), the Y-axis (horizontal front-back direction), and the Z-axis (vertical direction). The lead screw mechanism 5 includes a base 51 and a slider 52. The three bases 51 are respectively set vertically along the X-axis, Y-axis, and Z-axis. The base 51 in the Z-axis direction is fastened to the frame 1 by bolts, serving as a basic support. A Y-axis base 51 that can slide along the Z-axis base 51 is mounted on the Z-axis base 51, and an X-axis base 51 that can slide along the Y-axis base 51 is mounted on the Y-axis base 51. The clamp body 41 is fixedly connected to the slider 52, which covers the X-axis base 51 and is threadedly connected to the lead screw inside the X-axis base 51. During operation, the servo motor drives the lead screw to rotate, causing the slider 52 to slide along the base 51, thereby enabling the fixture body 41 to move along the corresponding axis. The movement of the X-axis base 51 and Y-axis base 51 is the same as that of the fixture body 41, both achieved by the lead screw driving the slider. The three axes work together to precisely move the fixture 4 to any preset position, completing the gripping, transfer, and positioning of the mold 2. It is worth noting that a separate fixture 4 is provided on one side of the worktable 11 for gripping the combined mold 2. This fixture 4 is independent of the fixture 4 used for gripping and transferring the mold 2. It can stably hold the combined mold 2 during the pouring of cake batter and demolding processes, ensuring that the combined mold 2 will not shift, and providing precise positioning for subsequent grouting, splicing, and demolding operations.

[0034] As attached Figure 1 and Figure 8 As shown, the lifting unit 8 is mounted below the workbench 11. Its core is a cylinder-driven lifting rod 81, with a lifting tray 82 mounted at the top of the lifting rod 81. The surface of the lifting tray 82 is coated with a food-grade non-stick coating to reduce adhesion between the cake and the lifting tray 82. The lifting stroke of the lifting tray 82 can be precisely controlled by a limit switch. Its initial position is completely retracted into the clearance hole of the workbench 11, without affecting the placement of the mold 2. During demolding, the lifting rod 81 rises vertically, and the lifting tray 82 passes through the clearance hole of the workbench 11 and the gap between the unfolded bottom plate 231, entering the through hole 22 of the mold 2, and smoothly ejecting the cake from the mold 2, completing the demolding operation. The lifting speed of the lifting tray 82 can be flexibly adjusted according to the hardness of the cake to avoid deformation or damage to the cake due to excessive lifting speed.

[0035] The core advantage of this device lies in its automated production of multi-flavor layered cakes. Its complete workflow includes five key steps: mold preparation, precise batter injection, mold assembly, baking and cooling, and demolding and recycling. The specific operating steps are as follows: Mold preparation: Place multiple empty molds 2 of the same specifications neatly on the mold storage platform of the frame 1, ensuring that the bottom plates 231 of each mold 2 are in a closed state and the through holes 22 are sealed. At this time, the device control system presets parameters such as the moving path of the clamp 4, the grouting volume, the docking position of the rotating tool 6, and the lifting stroke of the lifting part 8 according to production needs.

[0036] First injection: The control system drives the clamp 4 to move along the preset path to the mold storage platform, and takes one of the empty molds 2 through the opening 42. Then the clamping part 43 extends and retracts to stably clamp the mold body 21. The clamp 4 carries the mold 2 to the preset position of the workbench 11. After precise positioning, the clamping part 43 is released and the mold 2 is placed on the workbench 11. Then, the cylinder 9 drives the injection pipe 7 to descend to the top opening of the mold 2 and pours the first flavor of cake liquid into the mold 2 according to the preset injection volume. After the injection is completed, the injection pipe 7 rises and resets.

[0037] Mold assembly and second grouting: The clamp 4 moves back to the mold storage platform, grabs another empty mold 2, and moves it directly above the mold 2 that has been filled with the first flavor of cake batter. Through the matching of the fixing groove 24 and the fixing ring 25, the newly grabbed mold 2 is stably assembled with the lower mold 2, ensuring that the through holes 22 of the two molds 2 are coaxial after assembly. Then, the grouting pipe 7 descends again, pouring the second flavor of cake batter into the newly assembled upper mold 2, completing the second layer of grouting. To make multi-layered, multi-flavored cakes, the above mold assembly and grouting steps can be repeated until all flavors are layered.

[0038] Baking and Cooling: After all layers of batter are poured, clamp 4 holds the combined mold 2 and moves it to the preset baking area for high-temperature baking; after baking, the combined mold 2 is transferred to the cooling area for natural or forced cooling to room temperature to ensure stable cake formation.

[0039] Demolding and Recycling: After cooling, the clamp 4 transfers the combined mold 2 back to the lifting position on the worktable 11 for precise positioning; the control system drives the rotating tool 6 to move to the worm 38 of the combined mold 2, achieving precise docking between the electric screwdriver and the worm 38; the rotating tool 6 is started, driving the worm 38 to rotate, which in turn drives the worm wheel 36 and the first gear 31 to rotate synchronously; the first gear 31 drives the second gear 32 to rotate through meshing, and since the second gear 32 is fixedly connected to the mounting strip 37, it drives the mounting strip 37 to rotate around the axis of the second gear 32; at this time, the third gear 33 remains fixed and meshes with the fourth gear 34, which rotates around the mounting strip 37. During rotation, the fourth gear 34 rotates under the action of meshing force, and drives the fifth gear 35 meshing with it to rotate synchronously; the fifth gear 35 drives the bottom pieces 231 to rotate and move outward along the relief opening 211 until all the bottom pieces 231 are fully unfolded and the through hole 22 of the combined mold 2 is connected; finally, the lifting rod 81 is activated and rises smoothly in the vertical direction, the lifting tray 82 passes through the gap between the bottom pieces 231 and enters the through hole 22 of the mold 2, and pushes the layered cake out of the combined mold 2 as a whole, completing the demolding; after demolding, the lifting tray 82 descends and resets, and the clamp 4 transfers the empty mold 2 to the recycling area to wait for subsequent cleaning, and the entire production process is completed.

[0040] In summary, the device of this invention, through the collaborative design of multiple components including frame 1, mold 2, drive mechanism 3, clamp 4, lifting part 8, and supporting transmission components, possesses the following core advantages: First, it achieves full automation of mold switching, grouting, splicing, and demolding, significantly reducing manual intervention and improving production efficiency; second, it adopts a precise lead screw and gear transmission structure to ensure the positioning accuracy and motion stability of each component, improving the uniformity of cake layering and molding quality; third, the mold adopts a modular design, facilitating disassembly, cleaning, and replacement, adapting to the production needs of layered cakes of different sizes and flavors; fourth, it integrates multiple protective structures such as worm gear self-locking, elastic sealing, and anti-slip clamping, improving the safety and reliability of the device's operation, making it suitable for large-scale, standardized food processing scenarios.

[0041] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.

Demolding and Recycling: After cooling, the combined mold is transferred back to the worktable; the first gear is rotated, and through the linkage of the second, third, fourth, and fifth gears and the mounting strip, the bottom pieces are driven to rotate and move outward along the clearance opening until all the bottom pieces are fully unfolded and the through holes of the combined mold are connected; finally, the lifting tray rises through the gap between the bottom pieces and enters the through hole, pushing the layered cake out of the combined mold as a whole, completing the demolding; after demolding, the lifting tray descends and resets, and the fixture transfers the empty mold to the recycling area to await subsequent cleaning, completing the entire production process.
