Description

Technical Field

[0001] This invention relates to the field of dairy beverage technology, and in particular to a fully automated milk beverage mixing production equipment with zoned processing function and a method for enhancing meshing transmission. Background Technology

[0002] With rising living standards, consumers' demands for milk beverage flavors are becoming increasingly diversified. Single-flavor milk beverages can no longer satisfy consumers' ever-growing expectations for new tastes. Developing mixed-flavor milk beverages can provide richer flavor combinations, meeting the needs of consumption upgrading. Mixed-flavor milk beverages have higher added value and premium pricing power, enabling them to stand out in fierce market competition and capture a larger market share. However, any new product faces certain market development risks in its initial stages, with initial sales often being low. Furthermore, new products require multiple trials and adjustments to find the optimal mixing ratio and production process.

[0003] Current mixing methods utilize multiple independent mixing tanks, with the mixture transported via pipelines. Overall, the mixing tanks are large in volume, and the pipeline transport distances are long, resulting in low mixing production efficiency and significant resource waste. A typical material mixing device, such as the one disclosed in patent announcement number 219355932U, represents the characteristics of traditional mixing equipment. Furthermore, different milk beverage ingredients often require customized stirring methods to achieve good mixing results, which a single mixing device can hardly meet. Multiple sets of equipment not only incur high investment costs but also fail to achieve resource sharing, thus not meeting economic efficiency requirements.

[0004] Therefore, developing a new type of highly integrated, efficient, and multifunctional mixing production equipment suitable for small-batch or new product trial production can not only improve the production capacity and quality of mixed milk beverages and achieve standardized production, but also significantly reduce investment and operating costs. This multifunctional, small-scale mixing equipment is ideal for dairy companies developing new products or producing in small batches, effectively reducing trial production costs and shortening the new product launch cycle. This is of great significance for dairy companies to expand into the mixed-flavor milk beverage market and upgrade their products, and will also strongly promote the rapid development of the mixed-flavor milk beverage industry, enriching the public's food choices. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a fully automated milk beverage mixing and production equipment with zoned processing capabilities. Through the innovative design of the zoned transmission mechanism, this equipment achieves precise control over each processing zone, significantly improving the equipment's intelligence level and production efficiency.

[0006] The objective of this invention is achieved through the following technical solution: a fully automated milk beverage mixing and production equipment with zoned processing function, comprising:

[0007] Support frame;

[0008] A compartmentalized mixer is fixedly installed in the support frame. The compartmentalized mixer consists of an outer shell and an inner core, and has multiple independent mixing chambers inside.

[0009] A hollow main drive shaft runs through the compartmentalized mixer, and the main drive shaft is provided with multiple axially spaced extension holes.

[0010] Multiple sub-drive shafts are slidably nested with the main drive shaft through axially extending holes on the main drive shaft;

[0011] A drive coupling is fixedly connected to the sub-drive shaft and sleeved on the outer periphery of the main drive shaft, the lower end of the drive coupling having locking teeth;

[0012] The impeller is installed in the corresponding mixing chamber and is fixed to the outer periphery of the main drive shaft and rotates with it.

[0013] A driven connecting member fixed to the stirring impeller and engaging with the locking teeth of the driving connecting member;

[0014] The engagement and locking of the driving coupling and the driven coupling enables the driving force of the main drive shaft to be selectively transmitted to the stirring impeller, thereby driving the stirring action in the corresponding stirring chamber.

[0015] Preferably, the bottom of the compartmentalized mixer is equipped with a gas delivery system for conveying hot and cold media. The system can perform directional cooling or heating, improving the accuracy of ambient temperature measurement.

[0016] Preferably, an actuator is provided between the sub-drive shaft and the main drive shaft to allow them to slide relative to each other. The actuator can accurately control the sliding of the sub-drive shaft relative to the main drive shaft, thereby improving the precision of transmission control.

[0017] As a preferred option, the implementing agency includes:

[0018] A rotating component fixed to the outer end of each of the sub-drive shafts;

[0019] A lifting rod hinged to the rotating component;

[0020] A support platform that supports the lifting rod;

[0024] The convex arc segment is located at the upper end of the corresponding independent mixing chamber;

[0025] An annular groove and rollers are provided at the lower end of the meshing reinforcement component, wherein the annular groove can cooperate with the convex arc segment;

[0026] When the meshing reinforcement component rotates, the rollers roll on the convex arc segment, causing the meshing reinforcement component to move upward, so that the meshing reinforcement component enters the locking teeth and meshes with the outer ring teeth of the driven connector. This can enhance the meshing between the driven connector and the driving connector during transmission, improving transmission reliability.

[0027] Preferably, the meshing reinforcement component has a flange at its upper end; the corresponding independent stirring chamber has a limiting shell at its upper end, and the lower part of the limiting shell has a positioning ring that can accommodate the flange. This achieves limiting protection for the meshing reinforcement component and avoids malfunctions caused by excessive slippage.

[0028] Preferably, the drive connector has a spring pin on its circumferential surface that faces the opening of the positioning ring. The inner end face of the spring pin is a double-beveled surface, wherein the upper bevel can abut against the lower edge of the flange to support the engagement reinforcement component when the drive connector moves downward. This also serves as a limiting and protective mechanism for the engagement reinforcement component, improving system reliability.

[0029] Preferably, pulleys are provided at both ends of the main drive shaft, which is connected to the drive motor via belt drive. The use of a flexible connection avoids axial impact forces and improves transmission smoothness.

[0030] Preferably, the sub-drive shaft movement control mechanism is an electric actuator, including a screw motor and its driven lead screw and slider mechanism, to achieve precise stepping control of the sub-drive shaft. This enables high-precision stepping motion control and improves the system control accuracy.

[0031] To address the aforementioned problems, this invention also provides a method for enhancing the meshing transmission of a fully automated milk beverage mixing production equipment, comprising the following steps:

[0032] 1) An engagement enhancement component is provided above the outer ring teeth of the driven connector, allowing it to slide axially relative to the driven connector;

[0033] 2) A convex arc section is set at the upper end of the corresponding mixing chamber;

[0034] 3) An annular groove and rollers are provided at the lower end of the meshing reinforcement component, the annular groove being compatible with the convex arc segment;

[0035] 4) When the meshing enhancement component rotates, the roller rolls on the convex arc section, causing the meshing enhancement component to move upward, so that the meshing enhancement component enters the locking teeth of the drive connector and meshes with the outer ring teeth of the driven connector, thereby enhancing the meshing transmission.

[0036] 5) A flange is provided at the upper end of the meshing enhancement component;

[0037] 6) A limiting shell is provided at the upper end of the corresponding independent stirring chamber. The lower part of the limiting shell has a positioning ring that can accommodate the flange, so as to realize the limiting protection of the meshing enhancement component.

[0038] In summary, the present invention has the following advantages compared with the prior art:

[0039] This equipment utilizes a compartmentalized mixer to achieve zoned processing of different types of milk beverages, significantly improving production efficiency. Simultaneously, each compartment can be independently temperature-controlled, resulting in more precise temperature control. The equipment employs a main drive shaft and sub-drive shafts, allowing selective driving of different mixing chambers and enabling zoned control of different milk beverage types. Furthermore, a meshing lifting mechanism is incorporated, dynamically adjusting the meshing relationship during transmission, significantly enhancing transmission reliability. The addition of a sliding actuator allows for accurate control of sliding motion, improving transmission control precision. The use of electric actuators enables precise stepping motion control, further enhancing system control accuracy. Limit protection for key meshing components also improves reliability. Additionally, the use of soft connections enhances transmission smoothness. It can be seen that this invention, through the coordinated operation of various key mechanisms, achieves precise automated control of the entire milk beverage production process, enabling milk beverage production equipment to develop towards greater intelligence and precision, significantly improving production efficiency and product quality.

[0040] This invention also proposes a method for enhancing meshing transmission. By incorporating a meshing enhancement component, the meshing relationship can be dynamically adjusted during transmission, significantly strengthening the meshing strength between the driven and driving components and improving transmission reliability. The method utilizes the cooperation of a convex arc segment and an annular groove to achieve precise axial movement of the meshing enhancement component, making motion control more accurate.

Detailed Implementation

[0051] The present invention will now be further described with reference to the embodiments illustrated in all the accompanying drawings:

[0052] Example 1:

[0053] This embodiment describes a fully automated milk beverage mixing and production equipment that showcases an innovative technology designed to meet the growing market demand for diverse milk beverage flavors. The following is a detailed description of this equipment, and further explores its potential applications and advantages.

[0054] First, the load-bearing part of this equipment is its support frame 1A, which uses a high-strength stainless steel frame to ensure the stability and durability of the equipment, enabling it to perform excellently in industrial production environments.

[0055] The core component, mounted within support frame 1A, is the compartment mixer 2A. Vertically fixed within support frame 1A, the mixing tank is constructed of 30A4 stainless steel, featuring an outer shell 21A and an inner core 22A structure with a high degree of polishing (Ra ≤ 0.4μm) to ensure food hygiene and quality. The outer shell is also equipped with a 50mm polyurethane insulation layer to help maintain the required temperature conditions. The mixing tank contains multiple functional chambers, each capable of independent operation, allowing for the processing of various flavors of milk beverages within the same unit. This flexible multi-chamber design is a major innovation of this equipment. A gas delivery system 200 is located at the bottom of the compartment mixer 2A.

[0056] The core transmission system of the equipment includes a hollow main drive shaft 3A that runs through the mixing tank and multiple sub-drive shafts 5A. The main drive shaft 3A has multiple axially extending holes 31A spaced apart on its side wall; it is connected to an external power unit 4A and driven by a chain speed reducer. The multiple sub-drive shafts can slide and nest within the main drive shaft and can be selectively locked axially with it, thereby driving the stirring system in the corresponding chamber. The locking of the sub-drive shafts is controlled by a cylinder-driven actuator 10A. This transmission method achieves power distribution and precise control between different stirring chambers.

[0057] Each mixing chamber is equipped with an impeller 7A, and the impellers adopt a modular design for easy replacement. The impellers are driven by the engagement between the drive coupling 6A and the driven coupling 8A. In this way, even if the impeller needs to be replaced, the continuity of the transmission system will not be affected.

[0058] Compared to existing parallel mixing methods with multiple mixing tanks, the coaxial compartment design of this equipment effectively reduces equipment size and costs. Simultaneously, multiple mixing systems share the main shaft power and low-temperature environment, achieving rational resource utilization. Furthermore, the independent control of the working sequence of each mixing chamber allows for flexible organization of the mixing and production of various milk beverages.

[0059] The sub-drive shaft 5A features a clever structural design to achieve zoned drive control of different mixing chambers. Specifically, one end of the sub-drive shaft 5A corresponds to one of the axial extension holes 31A on the main drive shaft. The two shafts are axially locked together via a fixed or detachable connector, allowing the rotation of the main shaft to be transmitted to the sub-shaft. Simultaneously, the sub-drive shaft and the main drive shaft 3A can slide axially, with the sliding range limited by the size of the axial extension hole. This achieves both transmission and ensures the relative independence of the sub-drive shafts. At the other end, each sub-drive shaft 5A protrudes outside the main shaft, with gaps between them to allow for connecting devices at the outer end of each sub-drive shaft 5A, enabling external power to drive its movement.

[0060] In this embodiment, three sub-drive shafts of different lengths are provided, namely the first, second, and third sub-drive shafts, which are nested together using a coaxial sleeve arrangement. The first sub-drive shaft 5A1 has three sections of different diameters, and the second sub-drive shaft 5A2 has two sections of different diameters. The middle section of the first sub-drive shaft 5A1 is fitted into the lower section of the second sub-drive shaft 5A2, and the upper section of the first sub-drive shaft 5A1 is fitted into the upper section of the second sub-drive shaft 5A2. The second sub-drive shaft 5A2 is then fitted into the third sub-drive shaft 5A3. This series-nested design allows the different sub-drive shafts to rotate relatively independently while making reasonable use of the limited axial space, demonstrating the compactness and flexibility of the transmission system.

[0061] The drive coupling 6A, corresponding to each sub-drive shaft 5A, is a key component for realizing transmission. The drive coupling is fitted onto the outer circumference of the main drive shaft 3A in the form of a sliding sleeve, and is made of stainless steel, possessing high axial load capacity.

[0062] Each drive coupling 6A is fixedly connected to its corresponding sub-drive shaft 5A, allowing the drive coupling 6A to slide up and down with the sub-shaft and transmit the rotation of the sub-drive shaft 5A to the drive coupling. The lower end of the drive coupling 6A has a toothed engagement portion 6A2, which meshes with the matching teeth of the driven coupling 8A on the impeller 7A, forming a mechanical locking transmission, thereby driving the rotation of the impeller.

[0063] Through this connection method, the drive connector 6A not only transmits the rotation of the sub-shaft, but also selectively engages with the driven connector 8A to control the stirring action of the corresponding stirring chamber. This flexible and controllable drive method is an important part of the innovation of this equipment.

[0064] Below each drive coupling 6A is a corresponding stirring impeller 7A for the stirring chamber. It is fixed to the outer periphery of the main drive shaft 3A in a set form and is tightly fitted with the main drive shaft to achieve relative rotation.

[0065] The impeller 7A consists of a stainless steel frame 7A1 and multiple detachable blades 7A2 in the middle. The blades are detachably mounted to the frame by bolts or other means, so that even if the blades need to be replaced, it can be done quickly and easily.

[0066] By engaging the drive coupling 6A and the driven coupling 8A, the rotation of the main drive shaft can be precisely transmitted to the stirring impeller, causing the blades to rotate and thus stirring the liquid in the container. This modular design not only improves the versatility of the stirring system but also facilitates maintenance.

[0067] Fixed to the upper end face of the central shaft of each impeller 7A, and also fitted around the outer periphery of the main drive shaft 3A, is the driven coupling 8A. The driven coupling 8A achieves a tight rotatable fit with the main shaft.

[0068] The driven connector 8A has a toothed structure on its top surface that matches the locking teeth 6A2 on the drive connector 6A. When the drive connector 6A moves downward, the teeth of the two engage, so that the rotation of the drive connector 6A can be accurately transmitted to the driven connector 8A and the impeller 7A, driving them to rotate for stirring.

[0069] The engagement of the driven coupling 8A and the driving coupling 6A is key to achieving zoned drive control of each independent stirring system. When the sub-drive shaft 5A moves upward, the two couplings disengage, and the corresponding stirring system stops working. This flexible engagement method is an important part of the innovation of this equipment.

[0070] To achieve separate mixing of different flavored milk drinks, an independent mixing chamber 9A is provided on the outer periphery of each mixing impeller 7A. The mixing chamber 9A is fixed to the inner wall of the inner core 22A by a connecting piece 9A1.

[0071] The mixing chamber 9A has a detachable structure at at least one end, which allows for easy disassembly, maintenance, or replacement of the internal mixing impeller 7A. The mixing chamber 9A has corresponding inlet and outlet ports, which can be connected to an external pipeline system to realize the introduction of raw materials and the discharge of products.

[0072] This independent chamber design allows for the isolated mixing of products with different flavors, preventing cross-contamination and significantly improving product quality stability. Simultaneously, each chamber can be individually cleaned and disinfected, reducing the workload of disassembling the equipment.

[0073] The equipment is equipped with an actuator 10A that can be moved independently by applying force along the axial direction of the sub-drive shaft 5A. The actuator 10A includes:

[0074] (1) Ball pin rotating components 11, respectively fixed to the exposed end of each sub-drive shaft 5A;

[0075] (2) A lifting rod 12 pivotally connected to each rotating component 11;

[0076] (3) A support 13 for independently hinged one end of each lifting rod 12;

[0077] (4) A propulsion cylinder 14 that provides power to each lifting rod 12.

[0078] When the propulsion cylinder 14 applies force, the lifting rod 12 can drive the rotating component 11 and the sub-drive shaft 5A to move axially upward or downward, thereby disengaging or engaging the active and driven connecting parts, and thus controlling the start and stop of the corresponding stirring system.

[0079] The actuator 10A can also employ other existing technologies such as motor drive to achieve precise control of the sub-shaft movement. This flexible operation method is an important means of achieving zoned control of each independent mixing system.

[0080] After all equipment components are assembled, the power unit 4A is started to drive the main drive shaft 3A to rotate. At the same time, the ambient temperature inside the compartment mixer 2A is controlled through the cold or hot air delivery pipes.

[0081] Different types of materials to be mixed are injected into separate independent mixing chambers 9A. Then, for each mixing chamber, the corresponding cylinder 14 is controlled to exert thrust, causing the lifting rod 12 to rotate and pushing the corresponding sub-drive shaft 5A downward. In this way, the meshing teeth 6A2 of the drive connector 6A and the driven connector 8A are engaged and locked. At this time, the sub-drive shaft 5A drives the stirring impeller 7A to rotate through the main drive shaft 3A, thus mixing the materials in that chamber.

[0082] To stop stirring, release cylinder 14, return lifting rod 12 to its original position, move sub-drive shaft 5A upward, disengage the meshing teeth of the two connecting parts, and stop the stirring system from working.

[0083] This structural design and precise control enable selective mixing of materials within each independent mixing chamber. Simultaneously, different mixing chambers can share resources such as the power unit (4A) and low-temperature environment, achieving economical and efficient multi-mixing operations. Furthermore, if remixing of materials from different chambers is required, fluid transport can be directly utilized from the nearest point between the upper and lower chambers, simplifying operation and reducing the risk of quality loss.

[0084] To improve the meshing reliability between the meshing teeth 6A2 of the drive coupling 6A and the driven coupling 8A, a meshing lifting mechanism 100 was designed, the structure of which includes:

[0085] 1. The driven coupling 8A and the locking tooth 6A2 adopt a rectangular tooth design and have a certain axial height extension;

[0086] 2. A meshing reinforcement component 20A is fitted onto the outer ring teeth of the driven connecting member 8A. This component can slide up and down but does not rotate.

[0087] 3. A convex arc segment 30A is added to the upper center of the independent mixing chamber 9A, with a smooth transition between high and low points;

[0088] 4. The lower end of the meshing reinforcement component 20A has an annular groove 40A, which can be fitted with the convex arc section 30A; rollers 50A are radially arranged inside the annular groove;

[0089] 5. When the meshing reinforcement assembly 20A is not rotating, its own weight causes the annular groove 40A to intersect with the raised section 30A, and the roller 50A is located at the lowest point;

[0090] 6. When the meshing reinforcement assembly 20A rotates, the roller 50A rolls on the protruding section 30A, causing the meshing reinforcement assembly 20A to move upward as a whole;

[0091] 7. At this time, the meshing enhancement component 20A enters the locking tooth 6A2 and meshes with the outer ring tooth of the driven connector 8A.

[0092] This structural design allows the meshing parts to work together to drive the three components, greatly improving meshing strength and stability, which is an innovation of this equipment.

[0093] To ensure that the engagement enhancement assembly 20A can remain stably in the working position, the following additional structural design was implemented:

[0094] 1. An annular flange 21 is provided on the outer ring of the upper end of the meshing reinforcement component 20A;

[0095] 2. A limiting shell 60A is added to the upper center of the independent mixing chamber 9A, with an opening at the top and a recessed positioning ring 61 at the bottom;

[0096] 3. Multiple spring pins 70A are spaced apart on the circumferential surface of the drive connector 6A. The outer end of each pin is rounded and can fall into the positioning ring 61.

[0097] 4. The inner end of the spring pin 70A features a double-bevel design 71, with the upper bevel abutting against the lower edge of the flange 21;

[0098] 5. When the drive connector 6A moves downward, the round head enters the positioning ring 61, the spring pin 70A extends in, and the upper inclined surface abuts against the flange 21;

[0099] 6. At this time, the meshing enhancement component 20A is supported by the double inclined plane 71, so it will not fall even if the thrust of the cylinder 14 fails.

[0100] With this design, the meshing enhancement component 20A can remain stably in the working position, avoiding meshing failure when the cylinder thrust is insufficient, and also reducing the noise impact during operation.

[0101] Example 2:

[0102] Based on Example 1, the drive system is improved as follows:

[0103] 1. The transmission method of the main drive shaft 3A is changed to belt drive. Pulleys are added to both ends of the main drive shaft, and the shaft is connected to the drive motor via belts to achieve smoother and more efficient main shaft rotation;

[0104] 2. The movement control method of the sub-drive shaft 5A has been changed to an electric actuator, using a screw motor to drive the lead screw and slider mechanism to achieve precise step control of the sub-shaft movement, while reducing the maintenance cost of the pneumatic system.

[0105] 3. Add a frequency converter to adjust the spindle speed and the lifting speed of each sub-shaft, so as to achieve precise control of the stirring speed and time to meet the production needs of products of different specifications.

[0106] 4. Closed-loop feedback control is adopted to adjust the equipment operating parameters in real time according to parameters such as impeller speed and motor current to ensure the mixing effect.

[0107] Example 3:

[0108] Based on Example 1, the stirring system is improved as follows:

[0109] 1. The blades 7A2 of the impeller 7A are connected by magnetic adsorption, which enables quick blade replacement and reduces production transition time.

[0110] 2. The hydrodynamic design of the 7A2 blade was optimized by adopting a composite curved blade shape, which improved the stirring efficiency.

[0111] 3. Add a temperature measuring device and a sampling port to enable real-time monitoring of temperature and sample during the stirring process.

[0112] 4. Install multiple sets of 7A agitator impellers of different specifications, which can be quickly replaced according to production needs, thereby improving the applicability of the equipment.

[0113] 5. An independent electric temperature control device is added to the independent mixing chamber 9A to control the temperature changes during the mixing process.

[0114] The specific embodiments described herein are merely illustrative examples illustrating the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined in the appended technical solutions.
