Description

Technical Field

[0001] This invention relates to the field of baking food production equipment technology, specifically a fully automatic cake base turning machine. Background Technology

[0002] In the industrial production of baked goods, cake base demolding is a core process that determines the quality of the finished product and the efficiency of the production line. Fully automatic cake base turning machines, as the core equipment for automated cake base demolding, mainly use a turning mechanism to invert the mold containing the cake base 180°, automating the separation, receiving, and transfer of the cake base. They are widely adaptable to the large-scale continuous production needs of various cake bases, such as chiffon cakes and sponge cakes. The degree of automation in the demolding operation, the precision of motion coordination control, and the stability of finished product receiving directly affect the yield rate of baked goods and the continuous production efficiency of the production line. With the development of large-scale and standardized production in the baking industry, the industry has placed higher demands on the adaptability of fully automatic cake base turning machines to different working conditions, the non-destructive nature of demolding, production cleanliness, and the level of multi-motion coordinated control.

[0003] Existing fully automatic cake dough turning machines cannot achieve synchronized and coordinated control of the cake dough's impact vibration demolding action and the cake dough's supporting action during actual demolding operations. It is difficult to ensure both demolding efficiency and cake dough integrity during demolding. When faced with situations where the cake dough adheres strongly to the inner wall of the mold, increasing the impact vibration force to quickly break the adhesion can easily cause the cake dough to detach instantly and crack, deform, have its surface damaged, and crumble due to the impact of gravity. If the impact force is reduced, the adhesion between the cake dough and the mold cannot be effectively broken, resulting in poor demolding, slow production cycle, and low production efficiency. It cannot meet the stable and damage-free demolding requirements of cake doughs with different textures and adhesion forces in large-scale baking production. Therefore, in view of the above situation, there is an urgent need to develop a fully automatic cake dough turning machine to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic cake base turning machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fully automatic cake base turning machine includes a central demolding support frame, on which multiple step-by-step demolding lifting control components are arranged. These step-by-step demolding lifting control components are mounted on a central turning device, which is used to turn the central demolding support frame 180°. The machine also includes: A cake base demolding platform, located on the middle demolding support frame, is used to receive the cake base on the mold; The cake base demolding platform includes multiple cake base fixed serving plates and cake base movable serving plates. The multiple cake base fixed serving plates and cake base movable serving plates are spaced apart on the intermediate demolding support frame. The cake base fixed serving plates are fixedly connected to the intermediate demolding support frame, and the cake base movable serving plates can move up and down on the intermediate demolding support frame. And a demolding assistance system, which is located near the middle demolding support frame, is used to demold the cake base by impact and vibration, and simultaneously control the raising and lowering of the cake base moving serving plate.

[0006] As a further aspect of the present invention: the intermediate demolding support frame is provided with a sliding limiting part for guiding and sliding the cake base moving serving plate; The intermediate demolding support frame is also fixedly installed with a limiting flange, which is used to limit the movement of the cake base serving plate.

[0007] As a further aspect of the present invention, it also includes: a cake crumb collection hopper, which is fixedly installed on the intermediate demolding support frame. During the cake demolding process, the demolding auxiliary system controls the multiple cake crumb moving and placing plates to move upward. When a gap is formed between the multiple cake base fixed serving plates and the cake base movable serving plates, the crumbs generated during demolding fall into the cake base crumb collection hopper. And a slag discharge port, which is fixedly installed at the lowest end of the cake crumb collection hopper for discharging cake crumbs.

[0008] As a further aspect of the present invention: the demolding assistance system includes: A demolding assist flipping device is provided, which is located near the middle demolding support frame and has an L-shaped support frame fixedly installed on it. The demolding assist flipping device is used to drive the L-shaped support frame to flip. An impact lifting assembly is located on the L-shaped support frame; A multi-functional lifting support plate is provided, which is connected to the impact lifting assembly, and the multi-functional lifting support plate is provided with multiple impact control components. The impact lifting assembly is used to drive the multi-functional lifting support plate to reciprocate and lift. And a power unit, which is connected to the impact control component and the cake base moving serving plate, respectively.

[0009] As a further aspect of the present invention: the power unit includes: A power controller, which is fixedly mounted on the L-shaped support frame; The second flexible tube has one end connected to the power controller and the other end connected to multiple impact control components. And a flexible support tube, one end of which is connected to the power controller, and the other end of which is connected to the cake base moving serving plate through multiple cylinder liners.

[0010] As a further aspect of the present invention: the impact lifting assembly includes: A lifting bracket, which is fixedly connected to the L-shaped support frame; A telescopic cylinder is fixedly installed on the lifting bracket, and the output end of the telescopic cylinder is fixedly connected to the multi-functional lifting support plate. And a lifting port, which is opened on the L-shaped support frame and is used to place multiple impact control components.

[0011] As a further aspect of the present invention, it also includes: a limiting guide seat, which is fixedly installed on the L-shaped support frame, and the limiting guide seat is provided with multiple slots; The end of the multi-functional lifting support plate is fitted into a slot and slidably connected to the slot.

[0012] As a further aspect of the present invention: the impact control element includes: Demolding auxiliary impact sleeve, wherein there are multiple demolding auxiliary impact sleeves, all of which are fixedly installed on the multi-functional lifting support plate, and each demolding auxiliary impact sleeve is provided with a connecting hole; The connecting hole is connected to the flexible branch pipe 2 through the connecting channel provided on the multi-functional lifting support plate; And an impact control module, which is located on the demolding auxiliary impact sleeve and is connected to the connecting hole.

[0013] As a further aspect of the present invention: the impact control module includes: The lifting control cavity and the limiting cavity are both opened inside the demolding auxiliary impact sleeve, and the lifting control cavity and the limiting cavity are connected to each other. A sliding cylinder is slidably installed in the lifting control cavity, and a striking rod is fixedly installed on the sliding cylinder. The striking rod passes through the demolding auxiliary impact sleeve and is slidably connected to the demolding auxiliary impact sleeve. A spring, the spring being located within the limiting cavity, and the spring being sleeved on the striking rod; And an impact part, which is located at the bottom end of the demolding auxiliary impact sleeve.

[0014] As a further aspect of the present invention, the hardness of the impact part is greater than the hardness of the bottom end of the impact rod, which is used to provide different vibration effects when switching impact heads.

[0015] Compared with the prior art, the beneficial effects of the present invention are: It achieves synchronous and coordinated control of impact vibration demolding and cake base step-by-step support. The demolding auxiliary system can synchronously adjust the impact operation mode of the impact control component and the lifting action of the cake base moving plate. While breaking the adhesion between the cake base and the inner wall of the mold, the cake base is stably supported by the cake base fixed plate and the cake base moving plate set at intervals. This avoids the cake base from cracking and deforming due to gravity impact during demolding, and greatly improves the yield and operation stability of cake base demolding. It has dual-mode adaptive impact demolding capability. Through the automatic switching between the impact rod and the impact part in the impact control module, it can adapt to the high-frequency small-amplitude stable demolding under normal adhesion conditions and the large-amplitude strong vibration demolding requirements under strong adhesion conditions. It can flexibly cope with different demolding conditions without manual adjustment of the equipment structure, which significantly improves the equipment's adaptability and automation. It realizes the automated centralized collection and discharge of cake crumbs during the demolding process. By using the gap formed between the raised cake base and the fixed cake base, and the cake crumb collection hopper and discharge port fixed on the middle demolding support frame, the crumbs generated during demolding can be collected and discharged in a centralized manner throughout the process. This not only avoids the crumbs from contaminating the finished product and the production environment, but also reduces the difficulty of cleaning and maintaining the equipment, and ensures the food hygiene and safety of baking production. It improves the operational accuracy and stability of the core operation of the equipment. The sliding limit part and limit flange on the middle demolding support frame provide precise guidance and limit on the lifting and lowering movement of the cake base moving serving plate throughout the process. The limit guide seat on the L-shaped support frame provides double-sided guidance and limit on the reciprocating lifting and lowering of the multi-functional lifting support plate. This can effectively avoid the problems of horizontal deviation and movement jamming of the core operating components, and ensure the accuracy of the demolding operation and the long-term reliability of the equipment. The system adopts a dual-loop synchronous power control mode. Through the power controller and the two independent medium loops formed by the soft branch pipe one and the soft branch pipe two, it can simultaneously realize precise and independent control of the impact control component and the cake base moving plate. The control response speed is fast and the action synchronization is high. Moreover, the whole power system is adapted to food-grade production requirements and fully complies with the standard specifications for clean production of baked goods. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1-10 This invention provides a fully automatic cake base turning machine, including a central demolding support frame 1, on which multiple step-by-step demolding lifting control components 2 are provided. These step-by-step demolding lifting control components 2 are mounted on a central turning device, which is used to turn the central demolding support frame 1 180°. The machine also includes: A cake base demolding platform, located on the middle demolding support frame 1, is used to receive the cake base on the mold; The cake base demolding platform includes multiple cake base fixed serving plates 3 and cake base movable serving plates 4. The multiple cake base fixed serving plates 3 and cake base movable serving plates 4 are spaced apart on the intermediate demolding support frame 1. The cake base fixed serving plates 3 are fixedly connected to the intermediate demolding support frame 1, and the cake base movable serving plates 4 can move up and down on the intermediate demolding support frame 1. And a demolding assistance system, which is located near the middle demolding support frame 1, is used to demold the cake base by impact and vibration, and simultaneously control the lifting and lowering of the cake base moving serving plate 4.

[0030] In the baking industry, cake demolding is a core process that determines the quality of the finished product and production efficiency. Current technology mostly uses manual inverting and tapping of the mold for demolding, which is not only labor-intensive and inefficient, but also very easy to cause the edges of the cake to break and the internal structure to collapse, making it difficult to meet the needs of large-scale baking production. In this embodiment, after the cake is baked, the mold containing the cake base is transferred to the corresponding demolding station (the cake base with the mold can be rotated 180° using an existing flipping mechanism, so that it covers the cake base demolding platform; the demolding auxiliary system flips above the existing flipping mechanism; a pressure sensor is also installed on the cake base demolding platform to detect the cake base's descent in real time). At this time, the cake base fixed holding plate 3 and the cake base moving holding plate 4 in the cake base demolding platform are on the same horizontal reference plane, forming a complete and gapless receiving plane, avoiding the problem of local falling and deformation of the cake base during demolding; then the step-by-step demolding lifting control component 2 works with the demolding auxiliary system to start... The demolding assist system applies impact vibration to the cake base inside the mold, breaking the adhesion between the cake base and the inner wall of the mold (impacting the existing flipping mechanism). Simultaneously, it controls the intermediate demolding support frame 1 and the cake base demolding platform to move up and down in sync (so that the cake base maintains a small height relative to the demolding platform during the gradual detachment process, avoiding damage to the cake base from a large drop at once). This causes the cake base to gradually move downwards with the demolding platform until it is completely demolded. When the adhesion between the cake base and the inner wall of the mold is strong, and the cake base's descent is poor during impact (at which point the cake base no longer moves downwards with the demolding platform), the demolding assist system controls the interval... The relative positions of the fixed cake base plate 3 and the movable cake base plate 4 change. Even if the movable cake base plate 4 is raised, so that there is a slight or very small gap between the multiple movable cake base plates 4 and the cake base (to compensate for the gap when the cake base does not move down with the cake base demolding platform), the impact degree and other parameters controlled by the demolding assistance system are increased to overcome the adhesion between the cake base and the inner wall of the mold. However, under the support of the multiple movable cake base plates 4, the cake base is prevented from falling and causing a large impact that could damage it. In addition, when a gap is formed between the multiple fixed cake base plates 3 and the movable cake base plates 4, the crumbs generated during demolding fall into the cake base crumb collection. Inside the collection hopper 14, waste residue is collected. When the cake base is successfully demolded again after overcoming the adhesion force, the cake base moving holding plate 4 returns to its original position, and the demolding auxiliary system also returns to normal demolding operation until all cake bases are demolded. After demolding, another existing flipping mechanism (such as a conveyor belt with a flipping device) flips to above the cake base demolding platform. The existing flipping mechanism, together with the intermediate flipping device, drives the intermediate demolding support frame 1 and the step-by-step demolding lifting control component 2 to complete a 180° flip, so that the cake base on the cake base demolding platform falls onto the existing flipping mechanism (conveyor belt), thereby completing the demolding of the cake base and subsequent transportation. This will not be elaborated further here.

[0031] Therefore, through the coordinated use of vibration demolding and step-by-step support, it is possible to ensure that the cake base is completely removed from the mold. Furthermore, the alternating support of the cake base fixed placement plate 3 and the cake base moving placement plate 4 prevents the cake base from cracking or deforming due to gravity impact during demolding. This significantly improves the yield and automation of cake base demolding. At the same time, it is suitable for demolding various cake bases such as chiffon cakes and sponge cakes of different sizes and textures, and has strong versatility and operational stability.

[0032] In one embodiment of the present invention, please refer to Figures 1-4 The intermediate demolding support frame 1 is provided with a sliding limiting part 17 for guiding and sliding the cake base moving serving plate 4; The intermediate demolding support frame 1 is also fixedly installed with a limiting flange 18, which is used to limit the movement of the cake base plate 4.

[0033] It also includes: a cake crumb collection hopper 14, which is fixedly installed on the intermediate demolding support frame 1. During the cake demolding process, the demolding auxiliary system controls multiple cake crumb moving and holding plates 4 to move upward. When a gap is formed between the multiple cake base fixed serving plates 3 and the cake base movable serving plate 4, the crumbs generated during demolding fall into the cake base crumb collection hopper 14. And a slag discharge port 15, which is fixedly installed at the lowest end of the cake dough crumb collection hopper 14 for discharging cake dough crumbs.

[0034] In this embodiment, the sliding limit part 17 adopts a lower guide structure composed of a food-grade stainless steel linear guide rail and a matching slider. The slider is fixedly connected to the side of the cake base moving serving plate 4. The guide rail is arranged along the vertical direction of the middle demolding support frame 1. When the demolding auxiliary system drives the cake base moving serving plate 4 to perform lifting, positioning, and resetting operations, the sliding limit part 17 provides precise guidance and sliding limit for the movement trajectory of the cake base moving serving plate 4 throughout the entire process. This ensures that the cake base moving serving plate 4 always moves smoothly back and forth in the vertical direction, avoiding horizontal deviation and jamming of the cake base moving serving plate 4, and ensuring the cake base fixed serving plate 3 and the cake base moving serving plate are in harmony. The gaps between the serving plates 4 are uniform to prevent the cake base from getting stuck in the gaps and causing damage due to uneven gaps. At the same time, the limiting flange 18 fixed on the middle demolding support frame 1 adopts a lower limiting structure composed of food-grade polyurethane buffer blocks and stainless steel limiting seats, which are respectively arranged at the upper and lower ends of the sliding limiting part 17. This can limit the upper and lower limits of the lifting stroke of the cake base moving serving plate 4, preventing the cake base moving serving plate 4 from rising too much and causing rigid collision with the cake base, or falling too much and leaving the guide range of the sliding limiting part 17. At the same time, it can buffer the impact during the start and stop of the cake base moving serving plate 4, ensuring the stability and safety of the equipment operation. When the cake base moving plate 4 moves upward and forms a gap between it and the cake base fixed plate 3 to allow crumbs to pass through, cake crumbs, crust crumbs and other waste that fall off the cake base due to excessive auxiliary impact during demolding (increasing the impact to overcome adhesion, while there are fewer crumbs under normal impact) will fall directly into the cake base crumb collection hopper 14 fixedly installed below under the action of gravity through this gap. The cake base crumb collection hopper 14 adopts a V-shaped inclined lower hopper structure made of food-grade 304 stainless steel in one piece. The inner wall of the hopper is mirror polished, with no dead corners, and fully complies with the hygiene standards of baking food production.

[0035] In existing technologies, cake crumbs generated during demolding tend to scatter randomly, contaminating not only the finished cake base and the production environment but also easily falling into the transmission structure of the equipment, causing wear and jamming. This necessitates frequent shutdowns for cleaning, severely impacting continuous production efficiency. In this embodiment, a cake crumb collection hopper 14 centrally collects the waste generated during demolding, preventing crumbs from contaminating the finished product and equipment, ensuring food hygiene standards, and reducing equipment wear and failure rates. The cake crumb collection hopper 14 features a low-profile, inclined design, allowing collected crumbs to naturally converge at the lowest discharge port 15. The discharge port 15 is equipped with a quick-opening sealing plug, enabling workers to quickly clean and discharge crumbs, significantly reducing the difficulty of equipment cleaning and maintenance and improving continuous production efficiency.

[0036] In one embodiment of the present invention, please refer to Figures 1-10The demolding assistance system includes: A demolding auxiliary flipping device 5 is provided near the intermediate demolding support frame 1, and an L-shaped support frame 6 is fixedly installed on the demolding auxiliary flipping device 5. The demolding auxiliary flipping device 5 is used to drive the L-shaped support frame 6 to flip. Impact lifting assembly, which is located on the L-shaped support frame 6; A multi-functional lifting support plate 10 is connected to the impact lifting assembly, and the multi-functional lifting support plate 10 is provided with a plurality of impact control components. The impact lifting assembly is used to drive the multi-functional lifting support plate 10 to reciprocate lifting motion. And a power unit, which is connected to the impact control component and the cake base moving serving plate 4 respectively.

[0037] In this embodiment, the demolding auxiliary flipping device 5 can adopt a flipping drive module lower structure with a high-precision servo motor and a harmonic reducer. The flipping angle can be steplessly adjusted within the range of 0°-180°, and the repeatability positioning accuracy is ≤±0.02°. After the cake mold is flipped and placed on the cake base demolding platform by the existing flipping mechanism, the demolding auxiliary flipping device 5 can drive the L-shaped support frame 6 to complete the preset angle flipping adjustment, so that the impact lifting component, multi-functional lifting support plate 10 and impact control component on the L-shaped support frame 6 can be accurately flipped to the top of the existing flipping mechanism and accurately aligned with the back of the cake mold to be demolded. It can adapt to the demolding operation requirements of cake molds of different specifications, different placement angles and different numbers of mold positions, without the need for manual adjustment of the mold position, further improving the automation adaptability of the equipment. After the alignment adjustment is completed, the equipment enters the normal demolding working state. The power unit controls the impact rod 19 in the impact control component to be in the extended working state through the power controller 11. At this time, the impact lifting component is started, driving the multi-functional lifting support plate 10 to perform high-frequency small-amplitude reciprocating lifting motion along the preset vertical trajectory, thereby driving the multiple impact control components arranged on the multi-functional lifting support plate 10 to move synchronously. The extended impact rod 19 applies a slight impact to the existing flipping mechanism, and the basic adhesion between the cake base and the inner wall of the mold is broken by small-amplitude vibration, so as to achieve smooth and normal demolding. During this process, the power unit synchronously controls the cake base moving serving plate 4 to be in a stationary state, so that the cake base fixed serving plate 3 and the cake base moving serving plate 4 are always on the same horizontal plane, forming a complete and gapless receiving plane, avoiding local falling and deformation of the cake base. When a strong adhesion between the cake base and the inner wall of the mold is detected, and normal slight impacts cannot achieve smooth demolding (the demolding status of the cake base can be detected by a pressure sensor on the cake base demolding platform), the power unit switches the working mode through the power controller 11. On the one hand, it controls the retraction of the impact rod 19 in the impact control component, so that the harder impact part 23 can be engaged in the impact work (the impact rod 19 adopts a split structure of food-grade 304 stainless steel body and food-grade vapor phase silicone rubber coated impact head, and the impact part 23 is made of food-grade 304 austenitic stainless steel). In conjunction with the impact lifting assembly, it drives the multi-functional lifting support plate. The 10-axis reciprocating lifting mechanism increases the impact on the existing flipping mechanism, quickly breaking the strong adhesive force. On the other hand, it simultaneously controls the cake base moving plate 4 to move upward to fill the gap during the cake base demolding and falling, forming a stable support for the cake base. This avoids the cake base from being damaged or having waste fall due to the increased impact. The power unit realizes the synchronous switching control between the impact working mode and the cake base receiving action, which can not only adapt to the demolding requirements of different adhesive force conditions, but also ensure the cake base is received without damage throughout the process, greatly improving the demolding yield and the adaptability of the equipment to the working conditions.

[0038] In one embodiment of the present invention, please refer to Figures 1-10 The power unit includes: The power controller 11 is fixedly mounted on the L-shaped support frame 6; The second flexible tube 13 is connected at one end to the power controller 11 and at the other end to multiple impact control components. And a flexible support tube 12, one end of which is connected to the power controller 11, and the other end of which is connected to the cake base moving serving plate 4 through multiple cylinder liners.

[0039] Please see Figures 1-10 The impact lifting assembly includes: The lifting bracket 7 is fixedly connected to the L-shaped support frame 6; Telescopic cylinder 8 is fixedly installed on the lifting bracket 7, and the output end of the telescopic cylinder 8 is fixedly connected to the multi-functional lifting support plate 10. And a lifting port 21, which is opened on the L-shaped support frame 6, for placing multiple impact control components.

[0040] It also includes: a limiting guide seat 9, which is fixedly installed on the L-shaped support frame 6, and the limiting guide seat 9 is provided with multiple slots; The end of the multi-functional lifting support plate 10 is fitted into a slot and slidably connected to the slot.

[0041] In the baking food production scenario, food-grade clean production is a core requirement. The power controller 11 in this embodiment can adopt a hydraulic or pneumatic control mode, with priority given to the pneumatic control mode that complies with food production standards. The power controller 11 is a dual-loop control assembly composed of an integrated electric proportional valve group and a PLC control unit, which can independently regulate the on / off state, pressure and flow direction of the two media loops to achieve precise synchronous control of the impact working mode and the cake base receiving action. Specifically, the power controller 11 can adopt an IP65-rated pneumatic dual-loop synchronous control assembly adapted to baking food production scenarios, with the following specific structure: Hardware main body: The control box is made of 304 stainless steel and integrates an air source treatment unit, a dual-circuit electrical proportional valve group, a PLC control unit, an analog input module and a relay output module. It is suitable for humid and dusty production environments and complies with food hygiene standards.

[0042] Air source processing unit: The air inlet is connected in sequence to a food-grade oil-free air filter, a pressure reducing valve and an oil mist separator. The filtration accuracy is ≥5μm and the pressure regulation range is 0.1-0.8MPa. It provides the system with clean and oil-free compressed air to avoid polluting the production environment.

[0043] Dual-circuit valve group configuration: Two independent electro-proportional valves are set up. The first circuit is connected to the drive cylinder liner of the cake base moving plate 4 through the flexible branch pipe 12 to regulate its lifting stroke and pressure holding state. The second circuit is connected to the lifting control chamber 24 of the demolding auxiliary impact sleeve 16 through the flexible branch pipe 23 to regulate the extension and retraction of the impact rod 19 and the output pressure. Each valve is equipped with a two-position three-way solenoid valve to control the on / off of the control circuit and the switching of the medium flow direction.

[0044] Control and signal system: The Siemens S7-200 SMART PLC is used as the core. The analog input module is connected to the pressure sensor signal of the cake base demolding platform to collect the cake base demolding status in real time. The digital output module is connected to the servo drive signal of the two valve groups, the telescopic cylinder 8 and the demolding auxiliary flipping device 5 respectively. The built-in preset program realizes the automatic synchronous switching between normal demolding and strong adhesion demolding.

[0045] Matching operating structure: The external chamber is equipped with a food-grade silicone-sealed operating panel, which allows manual adjustment of pressure, stroke and tilt angle parameters. It is also equipped with an emergency stop button and operating status indicator lights to ensure operational safety.

[0046] Under normal demolding conditions, the power controller 11 delivers a medium with a set pressure to multiple impact control components through the flexible branch pipe 13 of the second medium circuit, driving the impact rod 19 inside the impact control component to extend stably and maintain a slight impact working state. At the same time, the power controller 11 inputs a pressure-holding medium into the cylinder sleeve connected to the cake base moving plate 4 through the flexible branch pipe 12 of the first medium circuit, keeping the cake base moving plate 4 in a stationary locked state, ensuring that the cake base moving plate 4 and the cake base fixed plate 3 are always on the same horizontal plane, forming a stable receiving plane. Both the flexible branch pipe 12 and the flexible branch pipe 13 adopt a flexible pipeline structure of food-grade platinum vulcanized silicone tubing, which can adapt to the reciprocating motion of the components, avoid pipeline pulling and damage, and ensure the long-term sealing and stability of the medium circuit. When the cake base has a strong adhesion and the working mode needs to be switched, the power controller 11 synchronously switches the control state of the dual circuit. The medium is controlled to flow in reverse through the soft branch pipe 13, which drives the impact rod 19 to retract (the spring 26 can be used to rebound). This switches the impact part 23 to the impact working end. At the same time, the driving medium is input into the cylinder liner through the soft branch pipe 12, which pushes the cake base moving plate 4 to move up and fill the position precisely, forming a stable support for the cake base and preventing the cake base from falling quickly due to strong impact, resulting in waste and damage. During the impact operation, the lifting bracket 7 fixed on the L-shaped support frame 6 provides stable vertical support for the telescopic cylinder 8. The telescopic cylinder 8 uses a food-grade stainless steel drive cylinder body, which can accurately drive the multi-functional lifting support plate 10 to perform reciprocating lifting motion with corresponding amplitude, adapting to the stroke requirements of both minor and strong impact modes. The lifting port 21 opened on the L-shaped support frame 6 provides sufficient lifting and avoidance space for the impact control components installed on the multi-functional lifting support plate 10, preventing the impact control components from colliding and interfering with the L-shaped support frame 6 during the lifting process, and ensuring the complete working stroke of the equipment. Meanwhile, the limiting guide seat 9 fixedly installed on the L-shaped support frame 6 adopts a double-sided symmetrical arrangement structure. Its slot is inlaid with a food-grade self-lubricating nylon bushing. The two ends of the multi-functional lifting support plate 10 are engaged in the corresponding slots, which can slide and guide and limit the two ends of the multi-functional lifting support plate 10 throughout the entire process. This ensures that the multi-functional lifting support plate 10 always maintains a horizontal state and lifts and lowers smoothly under the drive of the telescopic cylinder 8, avoiding the multi-functional lifting support plate 10 from tilting or jamming, which would cause the impact control components on it to be misaligned or the impact force to be uneven. This further improves the operating accuracy and operational stability of the equipment. The entire control system fully complies with the hygiene and safety standards for baking food production and is suitable for the needs of large-scale clean production.

[0047] In one embodiment of the present invention, please refer to Figures 1-10 The impact control component includes: Demolding auxiliary impact sleeve 16, there are multiple demolding auxiliary impact sleeves 16, all of which are fixedly installed on the multi-functional lifting support plate 10, and each demolding auxiliary impact sleeve 16 is provided with a connecting hole 22. The connecting hole 22 is connected to the flexible branch pipe 13 through the connecting channel 20 provided on the multifunctional lifting support plate 10. And an impact control module, which is located on the demolding auxiliary impact sleeve 16 and is connected to the connecting hole 22.

[0048] The impact control module includes: The lifting control cavity 24 and the limiting cavity 27 are both opened in the demolding auxiliary impact sleeve 16, and the lifting control cavity 24 and the limiting cavity 27 are connected to each other. A sliding cylinder 25 is slidably installed in the lifting control cavity 24, and a strike rod 19 is fixedly installed on the sliding cylinder 25. The strike rod 19 passes through the demolding auxiliary impact sleeve 16 and is slidably connected to the demolding auxiliary impact sleeve 16. Spring 26, the spring 26 is located in the limiting chamber 27, and the spring 26 is sleeved on the impact rod 19; And an impact part 23, which is located at the bottom end of the demolding auxiliary impact sleeve 16.

[0049] The hardness of the impact part 23 is greater than that of the bottom end of the impact rod 19, which is used to provide different vibration effects when switching impact heads.

[0050] In the cake demolding process, the force and mode of impact vibration directly determine the smoothness of demolding and the integrity of the cake. In this embodiment, under normal demolding conditions, the medium output by the power controller 11 is transported through the flexible branch pipe 13 to the pre-fabricated connecting channel 20 inside the multi-functional lifting support plate 10, and then precisely transported through the connecting holes 22 on the side wall of each demolding auxiliary impact sleeve 16 to the impact control module inside the demolding auxiliary impact sleeve 16. After the medium enters the lifting control cavity 24, it pushes the sliding cylinder 25 to overcome the elastic force of the spring 26 and move along the lifting control cavity 24. The sliding cylinder 8 drives the impact rod 19, which is fixedly connected to the sliding cylinder 25, to extend synchronously to the bottom end of the demolding auxiliary impact sleeve 16, so that the impact end of the impact rod 19 exceeds the working surface of the impact part 23. At this time, the telescopic cylinder 8 drives the multi-functional lifting support plate 10 to perform high-frequency small-amplitude reciprocating lifting and lowering. The extended impact rod 19 applies a slight impact to the existing flipping mechanism, and the basic adhesion between the cake base and the inner wall of the mold is broken by small-amplitude, high-frequency vibration, so as to achieve smooth and damage-free normal demolding. During this process, the cake base moving serving plate 4 is always in a stationary state, forming a complete receiving plane with the cake base fixed serving plate 3. When it is detected that the cake base has a large adhesion to the inner wall of the mold and normal slight impact cannot achieve smooth demolding, the power controller 11 switches the working state of the medium circuit, so that the medium in the lifting control cavity 24 is depressurized, the compressed spring 26 releases its elasticity, and pushes the sliding cylinder 25 and the impact rod 19 to quickly retract into the limiting cavity 27, so that the impact end of the impact rod 19 is completely retracted into the inner side of the impact part 23. At this time, the end face of the impact part 23 with higher hardness is put into operation as the impact working surface. Because the hardness of the impact part 23 is greater than the hardness of the bottom end of the impact rod 19, when the multi-functional lifting support plate 10 makes large-value reciprocating lifting, the impact part 23 can apply a greater degree of impact vibration to the existing flipping mechanism, quickly breaking the strong adhesion between the cake base and the inner wall of the mold. At the same time, the power controller 11 synchronously controls the cake base moving and placing plate 4 to move upward to fill the gap, forming a stable pre-support for the cake base, avoiding the problem of the cake base falling off instantly due to the increased impact degree and generating a gravitational impact, which would lead to the cake base being damaged and a large amount of waste falling off. The impact unit 23 can also adopt a quick-change structure design, allowing for the replacement of impact heads of different materials and hardness according to demolding requirements. This enables flexible switching of different impact vibration effects, adapting to the demolding needs of cake bases with different textures and adhesion strengths. Through pneumatic / hydraulic control, the impact rod 19 and the impact unit 23 can be automatically switched. Combined with the synchronous control of the cake base receiving action, this ensures both stable and damage-free demolding under normal conditions and rapid response to special conditions with strong adhesion. It guarantees the integrity of cake base demolding throughout the process, significantly improving the equipment's adaptability to different operating conditions and the yield of demolded products. Furthermore, all parts in contact with food are made of materials that meet national food safety standards, fully satisfying the hygiene requirements for baked goods production.
