Description

Technical Field

[0001] This invention relates to the field of soybean milk processing equipment technology, and more specifically, to a fine soybean milk pulverizer with a synchronous forward and reverse double-blade structure. Background Technology

[0002] Soy milk processing equipment has become a common household kitchen appliance. Existing soy milk makers generally rely on a single shaft driving a single set of grinding blades to rotate unidirectionally to complete the material crushing operation. The material rotates in the same direction as the blades, forming a directional vortex. The relative cutting speed between the material and the blades is relatively low, resulting in incomplete grinding of soybeans, a high content of soybean residue in the finished product, and difficulty in achieving the desired fineness of the soy milk. To improve the grinding effect, the industry has seen improvements such as double-layer blades and bidirectional rotary cutting. Among these, the existing patent CN202234794U (application number: 201120283369.X) discloses a soy milk maker with high grinding efficiency. This patent design uses two sets of blades, one above the other, rotating in opposite directions to improve grinding performance. However, the transmission structure of this existing patent is located inside the upper part of the soy milk maker's head, with the drive motor and reversing gear all integrated into the head cavity. This encroaches on the internal space of the container, limiting the food filling volume. Furthermore, the gear transmission structure is in a humid and hot steam environment, making it easy for moisture to penetrate the transmission meshing parts along the shaft gaps, leading to a high rate of gear corrosion and jamming failures.

[0003] Meanwhile, the aforementioned comparative patent's double-layer reverse blade body adopts a staggered, split transmission layout, requiring two independent power output shafts and matching transmission mechanisms. This results in a large number of parts, cumbersome assembly processes, and high production costs. Furthermore, since the blade body is mounted on the lower side of the machine head, disassembly and cleaning require separating the machine head from the cup, removing the transmission structure along with the blades. This makes the gears and shafts prone to slurry residue contamination, increasing the difficulty of daily cleaning and maintenance. In addition, this existing patent relies on a built-in motor in the machine head to output power vertically downwards. Constrained by the internal space of the machine head, the gear speed ratio design is limited, making it impossible to flexibly adjust the transmission speed ratio of the upper and lower blades. This leads to poor matching of the cutting linear speeds of the upper and lower blades, causing large particles of bean material to easily accumulate in the gap between the two blades, resulting in insufficient repeated crushing efficiency and a technical defect of not achieving the required fineness.

[0004] In addition, most conventional floor-standing soymilk makers on the market adopt a separate layout where the base supports the crushing tank. However, the single-motor, coaxial, nested, forward and reverse double-blade transmission structure is not yet widely used in floor-standing models. Most floor-standing models still use a single-blade, unidirectional crushing structure. Floor-standing models cannot be combined with forward and reverse double-blade crushing technology, and large-capacity floor-standing soymilk makers have long suffered from the industry pain points of insufficient crushing and large residue output. Based on the above-mentioned defects in the existing technology, this application proposes a fine crushing soymilk maker with a synchronous forward and reverse double-blade structure. Through the structure of the base with a built-in drive component and a double-layer coaxial blade assembly at the bottom of the crushing tank, it solves the technical problems of unreasonable transmission arrangement, poor sealing and protection, inconvenient cleaning, and insufficient crushing fineness in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a fine grinding soybean milk maker with a synchronous forward and reverse double-blade structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a fine grinding soybean milk maker with a synchronous forward and reverse double-blade structure, including a base, on which a grinding tank is installed. A grinding component is installed at the bottom inside the grinding tank. The grinding component adopts a double-layer grinding structure. A forward and reverse drive component is installed inside the base. The forward and reverse drive component drives the double-layer grinding structure of the grinding component to synchronously rotate forward and reverse through layered driving, thereby achieving fine grinding of soybean milk.

[0007] This design integrates the power drive structure inside the base, with the crushing components positioned low at the bottom of the crushing tank. Relying on the synchronous forward and reverse rotation of the double-layer crushing structure, it breaks through the limitations of traditional soymilk makers that use a single blade for unidirectional rotational crushing. This effectively eliminates the problems of materials flowing along the wall and remaining uncrushed, significantly increasing the shearing and crushing frequency of soybean materials, greatly improving the fineness of soymilk crushing, and reducing the content of soybean residue in the finished product.

[0008] Preferably, a pad is installed on the top of the base, and the crushing tank is fixed on the pad.

[0009] This feature uses a pad to isolate the crushing tank from the base, which can buffer the mechanical vibration generated during the crushing operation and avoid noise caused by rigid contact between the crushing tank and the base. At the same time, the pad can also play a role in anti-slip and heat insulation protection, improving the overall stability and safety of the machine.

[0010] Preferably, the crushing assembly includes an inner rotating shaft and an outer sleeve, the outer sleeve is fitted onto the inner rotating shaft, an upper crushing component is installed on the top outer side of the inner rotating shaft, the top height of the outer sleeve is lower than the top height of the inner rotating shaft, and a lower crushing component is installed on the top outer side of the outer sleeve.

[0011] This setup employs a coaxial nested rotating shaft structure to achieve a staggered arrangement of double-layer crushing components. The upper and lower layers of crushing components form a longitudinal stratified crushing zone, which can perform stratified shearing and crushing of materials at different heights within the crushing tank, expanding the material crushing coverage area and avoiding insufficient crushing of local materials. At the same time, the coaxial nested structure is compact, occupies little cavity space, and helps to increase the effective volume of the crushing tank.

[0012] Preferably, the forward and reverse drive assembly includes a servo motor, a drive shaft is mounted on the top output shaft of the servo motor, a first drive gear and a second drive gear are sequentially mounted on the drive shaft, a first driven gear is mounted on the lower end of the inner rotating shaft, the first drive gear meshes with the first driven gear, a second driven gear is mounted on the lower end of the outer sleeve, a transmission gear meshes on one side of the second drive gear, and one side of the transmission gear meshes with the second driven gear, so that when the drive shaft rotates, it drives the inner rotating shaft and the outer sleeve to rotate synchronously in opposite directions.

[0013] This setup utilizes a single servo motor in conjunction with a multi-stage gear meshing transmission structure. It enables the synchronous reverse rotation of the dual-layer crushing structure with only a single power source, eliminating the need for independent dual-motor drives. This simplifies the overall power structure, reduces equipment production costs and energy consumption, and ensures high transmission precision and stable power output. This guarantees the synchronous reversal of the dual-layer crushing components, ensuring a continuous and stable opposing shearing and crushing effect.

[0014] Preferably, the shaft of the transmission gear is rotatably connected to the inner wall of the base via a rotating shaft.

[0015] This feature provides fixed and limiting support for the transmission gears, ensuring that the shaft does not shift or wobble during gear meshing and rotation, maintaining the precise meshing of each gear stage, preventing gear slippage and jamming, and effectively improving the operational stability and service life of the transmission structure.

[0016] Preferably, a control panel is installed on one outer wall of the base, and the control panel controls the operation of the forward and reverse drive components through wiring.

[0017] This setup integrates an independent control structure, enabling intelligent control of equipment start-up and shutdown, and switching of operating modes. The operation is convenient and intuitive, while the centralized control layout facilitates neat wiring, reduces the probability of circuit failure, and improves the ease of equipment operation and safety.

[0018] Preferably, a first annular sealing ring is provided at the gap between the upper part of the inner rotating shaft and the upper end of the outer sleeve, and a second annular sealing ring is provided between the outer side of the outer sleeve and the bottom interface of the crushing tank.

[0019] This design uses a double-layer sealing structure to seal and protect the gap between the rotating shaft and the tank assembly gap, effectively preventing slurry and moisture inside the crushing tank from seeping into the transmission and electrical structures inside the base. This prevents gear corrosion, motor dampness, short circuits, and other malfunctions, significantly improving the equipment's waterproof and dustproof performance and operational reliability.

[0020] Preferably, the upper crushing components are arranged in a ring at equal intervals on the outer side of the inner rotating shaft, and the upper crushing components are elongated structures with a number of crushing teeth evenly installed on the outer side.

[0021] This setup employs a long strip toothed upper crushing structure. The evenly distributed ring layout expands the impact and crushing range of the upper material. The crushing teeth can perform preliminary splitting and crushing of large-particle bean materials, realizing material pre-crushing operations, providing a foundation for the fine cutting and crushing of the lower layer, and improving the overall crushing efficiency.

[0022] Preferably, the lower crushing components are arranged in a ring at equal intervals on the outer side of the outer sleeve, the lower crushing components are flat plate structures, and cutting edges are provided on both sides of the lower crushing components.

[0023] This setup employs a flat, lower-layer crushing structure with double-sided cutting edges, which can finely shear and grind the pre-crushed material in the upper layer. The double-sided cutting edge structure can adapt to both forward and reverse rotary cutting operations, eliminating cutting dead angles, further refining material particles, ensuring the smoothness of the finished soy milk, and effectively reducing residue.

[0024] Preferably, the diameter of the first driven gear is larger than the diameter of the first driving gear, and the diameters of the second driven gear, the transmission gear, and the second driving gear are the same.

[0025] This setup achieves variable speed transmission through differentiated gear diameter ratios, which can increase the output torque of the upper crusher and ensure sufficient power for crushing large particles. At the same time, the matching equal-diameter gear transmission structure ensures stable rotation speed of the lower crusher, realizing a combination of high and low speeds and high torque for layered crushing, balancing crushing force and crushing uniformity, and optimizing the overall crushing effect.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This fine grinding soybean milk maker with a synchronous forward and reverse double-blade structure adopts a structure layout with a built-in drive component in the base and a coaxial double-layer double blade at the bottom of the grinding tank. This is different from the traditional integrated transmission structure of the machine head. It effectively releases the effective volume inside the grinding tank and avoids the problem of the machine head structure occupying the storage space. At the same time, the drive transmission structure is completely housed inside the closed cavity of the base, away from the humid and steamy environment of the grinding tank. This greatly reduces the probability of gear corrosion, jamming, and moisture failure, and significantly improves the overall stability and service life of the machine.

[0027] 2. This finely grinding soy milk maker with a synchronous forward and reverse double-blade structure uses a single motor and gear-driven reversing transmission to achieve synchronous forward and reverse rotation of the coaxial double-layer blades. This eliminates the need for dual power sources or complex split transmission structures found in existing technologies, significantly simplifying the overall machine's component structure and reducing assembly difficulty and manufacturing costs. The staggered, layered blades work in reverse rotation to effectively prevent material from adhering to the wall and increasing the relative shearing speed between the material and the blades. This solves the problems of insufficient grinding, uneven particle size, and large amounts of soy residue found in traditional soy milk makers, effectively improving the fineness of the soy milk and the taste of the finished product.

[0028] 3. This synchronous forward and reverse double-blade fine grinding soy milk maker features a double-layer sealing structure to isolate and seal the gap between the rotating shaft and the tank assembly gap, completely eliminating problems such as soy milk leakage and water vapor backflow. Combined with the independent control structure on the base, the equipment is easy to operate and has excellent waterproof and dustproof performance. At the same time, the differentiated gear ratio achieves layered power matching, balancing crushing torque and grinding uniformity, adapting to large-capacity floor-standing grinding conditions, and making up for the industry shortcoming of existing floor-standing soy milk makers that cannot achieve double-blade forward and reverse fine grinding.

[0031] 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.

[0032] This invention provides a fine grinding soybean milk maker with a synchronous forward and reverse double-blade structure, such as... Figures 1-6 As shown, it includes a base 1, a crushing tank 2 mounted on the base 1, a crushing component 3 installed inside the crushing tank 2, and a forward and reverse drive component 4 arranged inside the base 1.

[0033] The base 1 serves as the basic structure for bearing and encapsulating the entire machine. It supports the crushing tank 2 and houses and fixes the forward and reverse drive assembly 4, providing positioning support and protective isolation for all working structures of the machine. The crushing tank 2 is fixedly installed above the base 1, providing a sealed working chamber for crushing and pulping soybean raw materials. The crushing assembly 3 is assembled inside the lower part of the crushing tank 2, adopting a double-layer crushing structure, for layered shearing and impact crushing of the internal materials. The forward and reverse drive assembly 4 is integrated and installed inside the base 1, serving as the sole power output and reversing transmission structure of the entire machine, for driving the double-layer crushing structure of the crushing assembly 3 to achieve synchronous forward and reverse rotation.

[0034] The base 1 has a hollow cavity structure, which can realize the enclosed storage and installation of the forward and reverse drive component 4. It can effectively isolate external moisture and dust, prevent the transmission structure from getting damp and corroding, and ensure the stable operation of the internal transmission structure.

[0035] The crushing tank 2 is a vertically arranged cavity structure, forming a complete material crushing space inside. It can hold soybean raw materials and water, and together with the bottom crushing component 3, it completes fine crushing and pulping operations. The cavity structure can effectively constrain the movement trajectory of materials and improve the material crushing and circulation effect.

[0036] The crushing component 3 adopts a double-layer split coaxial crushing structure. It forms a multi-stage crushing zone by relying on the crushing components arranged in upper and lower layers, which can crush materials in layers and steps, effectively improving the uniformity and fineness of material crushing.

[0037] By dividing the entire machine into a base 1 bearing structure, a crushing tank 2 cavity structure, a double-layer crushing component 3, and a built-in forward and reverse rotation drive component 4 in the base 1, a modular layout of the entire machine is achieved, with clear structural partitions and convenient assembly and maintenance. Relying on the built-in drive in the base 1 and the low-level crushing structure in the tank, the traditional head transmission layout is changed, effectively avoiding the problem of water vapor erosion of the transmission structure. At the same time, relying on the synchronous forward and reverse rotation of the double-layer crushing structure, the defect of material sticking to the wall and stagnating is eliminated, which greatly improves the fineness of soybean milk crushing and reduces the amount of soybean residue.

[0038] In this embodiment, a pad 11 is fixedly installed on the top of the base 1, and the crushing tank 2 is fixedly assembled on the upper surface of the pad 11 to achieve isolated assembly and installation of the crushing tank 2 and the base 1; the forward and reverse drive assembly 4 is arranged in a closed manner inside the hollow cavity of the base 1, and its power output end passes through the bottom of the base 1 and the crushing tank 2, and is connected to the crushing assembly 3 to achieve low-level power transmission.

[0039] The pad 11 is sandwiched between the base 1 and the crushing tank 2, which can effectively buffer the mechanical vibration generated during the crushing operation, avoid the noise generated by the rigid collision between the crushing tank 2 and the base 1, and at the same time play a role in heat insulation and anti-slip protection, improving the overall stability and safety of the machine. The built-in drive layout of the base 1 can completely isolate the transmission structure from the crushing wet area, prevent slurry and water vapor from entering the gear transmission structure, effectively avoid gear jamming and corrosion failure, and extend the service life of the equipment.

[0040] Specifically, the crushing component 3 includes an inner rotating shaft 31 and an outer sleeve 32 arranged coaxially. The outer sleeve 32 is movably sleeved on the outside of the inner rotating shaft 31. The two form a coaxial double-layer transmission structure that can rotate independently in opposite directions. Different levels of crushing components are respectively assembled at the upper ends of the inner rotating shaft 31 and the outer sleeve 32 to realize double-layer crushing operation.

[0041] The coaxial nested rotating shaft structure has a compact layout, occupies little internal space in the crushing tank 2, and can maximize the retention of the effective volume of the crushing tank 2. At the same time, the two-layer rotating shafts operate independently without interfering with each other, and can stably drive the upper and lower crushing parts to rotate synchronously in opposite directions, providing a stable structural foundation for bidirectional shearing and crushing.

[0042] Furthermore, an upper crushing component 311 is fixedly assembled on the top outer side of the inner rotating shaft 31, the top height of the outer sleeve 32 is lower than the top height of the inner rotating shaft 31, and a lower crushing component 321 is fixedly assembled on the top outer side of the outer sleeve 32, so that the upper crushing component 311 and the lower crushing component 321 form a vertically staggered layered structure.

[0043] The staggered, layered layout of the crushing components creates varying crushing zones within the crushing tank 2, enabling full-coverage crushing of materials at different heights within the tank. This prevents materials from remaining in certain areas for extended periods without being crushed, effectively improving the overall uniformity of material crushing and enhancing the fineness of the pulp.

[0044] Specifically, the forward and reverse drive assembly 4 includes a servo motor 41, a drive shaft 42, a first drive gear 43, a second drive gear 45, a transmission gear 44, a first driven gear 312, and a second driven gear 322. The servo motor 41 is fixedly installed in the internal cavity of the base 1, and the drive shaft 42 is coaxially fixedly mounted on the top output end of the servo motor 41. The first drive gear 43 and the second drive gear 45 are sequentially fixedly installed on the outside of the drive shaft 42 and rotate synchronously with the drive shaft 42.

[0045] Using a single servo motor 41 as the sole power source, combined with a multi-stage gear transmission structure, bidirectional power output can be achieved without the need for dual power equipment, simplifying the overall power structure, reducing equipment energy consumption and production costs. The gear transmission structure has high transmission accuracy and stable power output, ensuring the synchronous operation of the crushed parts.

[0046] Furthermore, a first driven gear 312 is fixedly installed at the lower end of the inner rotating shaft 31, and a first driving gear 43 and a first driven gear 312 form a meshing transmission engagement. A second driven gear 322 is fixedly installed at the lower end of the outer sleeve 32, and a second driving gear 45 meshes with a transmission gear 44 on the side. The other side of the transmission gear 44 meshes with the second driven gear 322 for transmission.

[0047] Through a multi-stage gear meshing reversing transmission structure, the unidirectional rotational power of the servo motor 41 is split into two sets of reverse synchronous power, which drive the inner rotating shaft 31 and the outer sleeve 32 to rotate in opposite directions respectively. The structure has strong linkage and fast transmission response, and can stably realize synchronous forward and reverse operation of the double-layer crushing structure.

[0048] Specifically, a fixed rotating shaft is mounted at the center of the transmission gear 44, and the transmission gear 44 is rotatably connected to a preset mounting point on the inner wall of the base 1 through the rotating shaft, so as to realize the fixed-point limiting rotation of the transmission gear 44.

[0049] The fixed-point limiting installation structure of transmission gear 44 can effectively constrain the rotation axis of transmission gear 44, avoid the problems of misalignment, shaking, and tooth dislodgement during gear meshing, ensure the meshing accuracy of each level of gear, improve the operational stability of the transmission structure, and reduce the probability of equipment failure.

[0050] Furthermore, a control panel 12 is fixedly embedded on the outer wall of the base 1. The control panel 12 is electrically connected to the servo motor 41 inside the base 1 through built-in circuitry, forming a control terminal for the start-up, shutdown and operation condition regulation of the whole machine.

[0051] The external control panel features a well-organized layout and intuitive operation, allowing for precise control of equipment start / stop, crushing time, and working mode. The centralized wiring layout also prevents messy and worn wiring, improving both electrical safety and ease of operation.

[0052] Specifically, an annular first sealing ring 313 is provided at the nesting gap between the upper part of the inner rotating shaft 31 and the upper end of the outer sleeve 32, and an annular second sealing ring 323 is provided at the through assembly gap between the outer wall of the outer sleeve 32 and the bottom of the crushing tank 2, forming a double-layer sealing protection structure.

[0053] The double-layer annular sealing ring can seal the gap between the rotating shaft and the tank assembly gap in all directions, effectively preventing the slurry and water vapor inside the crushing tank 2 from seeping downward into the base 1, preventing the motor from getting damp, the gears from rusting, and the circuit from short-circuiting, and greatly improving the waterproof and dustproof performance and operational reliability of the whole machine.

[0054] Furthermore, the upper crushing components 311 are arranged in a ring at equal intervals along the outer side of the inner rotating shaft 31. The upper crushing components 311 are set as a long strip structure, with several crushing teeth 3111 structures evenly distributed on their outer side, forming a tooth-impact upper crushing structure.

[0055] The ring-shaped, evenly distributed, long strip-shaped toothed crushing structure has a wide impact coverage area, which can initially split, impact, and disperse large-particle bean raw materials, realize the pre-crushing operation of materials, reduce the hardness of large materials, provide a foundation for the subsequent fine shearing and crushing, and improve the overall crushing efficiency.

[0056] Furthermore, the lower crushing components 321 are arranged in a ring at equal intervals along the outer side of the outer sleeve 32. The lower crushing components 321 are configured as a flat plate structure, and cutting edges 3211 are provided on both sides of the lower crushing components 321 to form a double-sided cutting edge shearing structure.

[0057] The flat crushing structure with double-sided cutting blades 3211 can be adapted to bidirectional rotation operation, with no cutting dead angles. It can perform fine shearing and grinding on the fine materials after pre-crushing in the upper layer, further refining the material particles, effectively reducing soybean residue, and improving the smoothness and taste of the finished soy milk.

[0058] Specifically, the diameter of the first driven gear 312 is larger than that of the first driving gear 43, while the diameters of the second driving gear 45, the transmission gear 44, and the second driven gear 322 are consistent, forming a differentiated speed transmission structure.

[0059] Differentiated gear diameter ratios can achieve torque amplification, enhance the crushing power of the upper crusher 311, and ensure that large particles are fully crushed. Equal diameter gear transmission can ensure that the lower crusher 321 rotates at a uniform and stable speed, achieving a layered crushing effect of high torque crushing in the upper layer and uniform speed fine grinding in the lower layer, thus optimizing the overall pulping quality.

[0060] When using this invention, the equipment is first installed and deployed: the pad 11 is fixedly installed on the top of the base 1, and the crushing tank 2 is fixedly assembled on the upper surface of the pad 11 to complete the isolation assembly of the crushing tank 2 and the base 1; the forward and reverse drive assembly 4 is fixedly installed in the internal cavity of the base 1 to ensure that the servo motor 41 and the gears at each stage are assembled in place and mesh accurately; the inner rotating shaft 31 and the outer sleeve 32 of the crushing assembly 3 are installed through the bottom of the crushing tank 2 to complete the assembly of the double-layer crushing structure, and the first sealing ring 313 and the second sealing ring 323 are installed respectively to seal the assembly gap; finally, the external control panel 12 is connected to the internal drive assembly to complete the installation and deployment of the whole machine.

[0061] After the equipment is installed, the equipment debugging work is carried out: start the equipment through the external control panel 12, the servo motor 41 is powered on and runs, driving the drive shaft 42 and the gears of each stage to drive synchronously. Observe whether the inner rotating shaft 31 and the outer sleeve 32 achieve synchronous reverse rotation. Check that the crushed parts run smoothly without jamming or abnormal noise, and that there is no leakage in the sealing structure. After confirming that each transmission structure, control structure and sealing structure is working normally, the equipment debugging is completed and the equipment enters the work preparation state.

[0062] Entering the formal crushing and pulping stage, a certain amount of soybean raw materials and water are put into the crushing tank 2. The crushing program is started through the control panel 12. The servo motor 41 continuously outputs unidirectional rotational power, driving the first drive gear 43 and the second drive gear 45 to operate synchronously. The first drive gear 43 drives the inner rotating shaft 31 and the upper crushing part 311 to rotate forward through the first driven gear 312. The second drive gear 45 drives the second driven gear 322, the outer sleeve 32 and the lower crushing part 321 to rotate in the opposite direction synchronously through the transmission gear 44. The double-layer crushing structure operates at high speed in opposite directions, continuously impacting, shearing and grinding the material in the tank.

[0063] During the crushing process, the upper toothed crusher 311 continuously pre-breaks and crushes large pieces of material, while the lower double-sided blade crusher 321 finely grinds small pieces of material. The bidirectional rotating crushing structure breaks the unidirectional vortex state of the material, allowing the material to continuously circulate and flow within the tank, repeatedly passing through the double-layer crushing zone, which greatly improves the uniformity and fineness of the crushing. The double-layer sealing ring continuously plays a sealing and protective role, preventing slurry moisture from seeping into the base 1 and ensuring the continuous and stable operation of the drive components.

[0064] After the preset grinding time is completed, the equipment will automatically stop running, completing the fine grinding of soy milk. After the operation is completed, turn off the power of the equipment and you can directly take out the finished soy milk from the crushing tank 2. At the same time, you can clean the inside of the crushing tank 2 and the double-layer crushing components 3 with clean water. After cleaning, wipe the equipment dry and store it neatly. The entire operation of the equipment is over.
