Description

Technical Field

[0001] This utility model relates to the field of ingredient dispensing technology, and in particular to a solid particle storage, grinding and spraying device. Background Technology

[0002] With the fast pace of modern life, people's demand for convenient and efficient kitchen cooking equipment is increasing. As a device that can automatically complete cooking tasks, the stir-fry machine has received widespread attention because it frees up people's hands and quickly produces delicious dishes. Among the many key components of a stir-fry machine, the solid ingredient dispensing device is particularly important. It is responsible for accurately dispensing solid seasonings such as salt, sugar, and MSG during the cooking process, thus directly affecting the final taste of the dish.

[0003] However, existing solid ingredient dispensing devices have a significant drawback: the solid ingredients inside are prone to moisture absorption and spoilage. Moisture in the air gradually seeps into the seasoning storage area, causing the solid seasonings to absorb moisture and clump together. This not only affects their flowability but can also breed bacteria and mold, thus impacting the quality and safety of the seasonings. Once damp and spoiled seasonings are added to dishes, they not only ruin the flavor but may also pose a potential threat to consumers' health. Furthermore, the moisture problem of solid ingredients limits their long-term preservation in the cooking machine. Users need to frequently replace seasonings, increasing operating costs and operational complexity, and reducing the convenience and practicality of the cooking machine.

[0004] Therefore, how to effectively solve the problem of moisture prevention for solid ingredients, extend the shelf life of seasonings, and ensure the accuracy and safety of their addition during cooking has become a key issue that urgently needs to be addressed in the current technology of cooking machines. Utility Model Content

[0005] The purpose of this invention is to provide a solid particle storage, grinding, and spraying device to solve the aforementioned technical problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a solid particle storage, grinding, and spraying device, comprising:

[0007] The support includes a horizontal base and a vertical perforated plate fixed to the horizontal base;

[0008] A storage and grinding mechanism includes a first motor fixed to the perforated plate and a storage and grinding bottle connected to the output shaft of the first motor. The storage and grinding bottle has a downward-facing opening and is rotatably fitted with a grinding head. The grinding head is positioned on the perforated plate by a fixed bracket. The first motor drives the storage bottle to rotate relative to the grinding head to grind solid granular seasonings.

[0009] The weighing mechanism, located below the grinding head, includes a weighing plate, a pressure sensor located at the bottom of the weighing plate, and a second motor fixed to the perforated plate for driving the weighing plate to tilt.

[0010] A funnel mechanism includes a funnel and a funnel support for fixing the funnel, wherein the funnel is located directly below the weighing plate and the funnel support is fixedly connected to the orifice plate.

[0011] The feeding mechanism, located below the funnel mechanism, includes a measuring spoon, a fourth motor that drives the measuring spoon to move horizontally, and a third motor that drives the measuring spoon to flip.

[0012] In some optional embodiments of this utility model, the storage bottle body of the storage grinding bottle is detachably fixed in a set of rotating clamps, and the rotating clamps are connected to the first motor through a connecting frame and driven to rotate by the first motor.

[0013] In some alternative embodiments of this utility model, the grinding head is detachably fixed in a set of fixing clamps, and the fixing clamps are fixedly connected to the perforated plate through a fixing bracket.

[0014] In some alternative embodiments of this utility model, the grinding head includes a grinding core, a grinding inner ring, a shell, and a fine-tuning mechanism, used to grind solid particles into powder.

[0015] In some alternative embodiments of this utility model, the grinding core of the grinding head is provided with a logarithmic conical spiral structure, the shape of which is determined by the logarithmic conical spiral and the arc of its normal plane.

[0016] Specifically, the equation for the logarithmic conic spiral is:

[0017]

[0018] In the formula, t is a parameter of the logarithmic conic spiral, and t∈[t1,t2], m g n is a parameter related to the helix radius of the logarithmic conic helix. g These are parameters related to the pitch of the logarithmic conical helix.

[0019] According to the equation of the logarithmic conic spiral, a centerline can be obtained along the direction of its normal vector. Using the circular arc as the scanning section, the centerline as the scanning line, and the logarithmic conic spiral as the guiding line, the logarithmic conic spiral structure is obtained.

[0020] In the above scheme, the logarithmic conical spiral structure distributed on the grinding core can improve grinding efficiency and accuracy, ensure that the particle size of the ground solid particles is uniform, and avoid uneven feeding caused by different particle sizes.

[0021] In some optional embodiments of this utility model, multiple storage and grinding mechanisms are arranged laterally along the perforated plate, each corresponding to a type of fixed solid granular seasoning. This allows for the simultaneous storage and grinding of multiple solid granular seasonings to meet diverse cooking needs. The device design offers good scalability; the number of storage and grinding mechanisms can be increased or decreased according to actual requirements to adapt to different sizes of cooking machines.

[0022] In some optional embodiments of this utility model, the weighing mechanism further includes a rotating component and a base plate. The weighing plate is mounted on the base plate via a pressure sensor and a pad. The second motor drives the rotating component to tilt the weighing plate. The weighing mechanism, employing a combination of a pressure sensor and a rotating component, can provide real-time feedback of weighing information. The control system precisely controls the amount of solid particulate seasoning added, ensuring consistent flavor in the dishes.

[0023] In some alternative embodiments of this utility model, the feeding mechanism further includes a rotary table, the measuring spoon is connected to a third motor via a rotating shaft, and the fourth motor drives the rotary table to move the measuring spoon to the target position.

[0024] In some optional embodiments of this utility model, the perforated plate has a plurality of ventilation holes. The presence of ventilation holes on the perforated plate ensures ventilation inside the device while preventing moisture from accumulating inside, further enhancing the moisture-proof effect.

[0025] Furthermore, the storage bottle and grinding head are detachably connected and sealed with a rubber sealing ring. Both the storage bottle and grinding head are detachably fixed, facilitating user replacement of solid granular seasonings or cleaning of the grinding head, reducing equipment maintenance costs and operational difficulty. By installing a rubber sealing ring between the storage bottle and grinding head, moisture in the air can be effectively prevented from penetrating into the seasoning storage area, thus avoiding moisture absorption and clumping of the solid granular seasonings. This solves the problem of solid ingredients easily becoming damp and deteriorating in existing technologies, extending the shelf life of solid granular seasonings.

[0026] This utility model also provides a cooking machine, including a cooking execution device, a control system, and a solid particle storage, grinding, and spraying device; the solid particle storage, grinding, and spraying device adopts any of the above-mentioned solid particle storage, grinding, and spraying devices; the cooking execution device includes a stove and a stirring mechanism; the control system is communicatively connected to the storage and grinding mechanism, weighing mechanism, feeding mechanism, and cooking execution device in the solid particle storage, grinding, and spraying device, and is used to coordinate the operating sequence of each mechanism.

[0027] By coordinating the operation sequence of each mechanism through the control system, the automatic grinding, weighing and dispensing of solid granular seasonings are achieved, reducing manual intervention and improving cooking efficiency and precision.

[0028] Compared with the prior art, the present invention discloses at least the following beneficial effects:

[0029] This invention, through its innovative structural design and automated control system, effectively solves the problems of moisture absorption, uneven grinding, and inaccurate weighing in existing solid granule seasoning dispensing devices for cooking machines.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Reference Figures 1 to 5 As shown, this utility model provides a solid particle storage, grinding, and spraying device, including a storage and grinding mechanism 1, a weighing mechanism 2, a funnel mechanism, a feeding mechanism 3, and a support base for fixing the above mechanisms. Specifically, the support base includes a horizontal base and a perforated plate 18 vertically fixed on the horizontal base. The perforated plate 18 is vertically arranged and used to install the storage and grinding mechanism 1 and the weighing mechanism 2. The feeding mechanism 3 is fixed on the horizontal base. The perforated plate 18 has several ventilation holes.

[0040] In one specific embodiment, multiple storage and grinding mechanisms 1 are arranged at intervals along the width direction of the perforated plate 18. Each storage and grinding mechanism 1 can be used to store and grind different solid granular seasonings, such as salt, sugar, monosodium glutamate, pepper, etc.

[0041] In this embodiment, two storage and grinding mechanisms 1 are used as an example for description, such as... Figure 1 As shown, two storage and grinding mechanisms 1 are fixed on the perforated plate 18. Each storage and grinding mechanism 1 includes a storage and grinding bottle 9, which stores commonly used salt and sugar, respectively. Each storage and grinding mechanism 1 is fixedly installed on the perforated plate 18 via a first extension bracket 4, and the installation position of each storage and grinding mechanism 1 is determined as needed.

[0042] In one specific embodiment, such as Figure 2As shown, the storage and grinding mechanism 1 includes a first motor frame 5, a first motor 6, a connecting frame 8, a rotating frame 16, a storage and grinding bottle 9, a rotating clamp 10, a fixed clamp 13, and a fixed bracket 20. The storage and grinding bottle 9 includes a storage bottle body and a grinding head 12, which are rotatably fitted and sealed by a rubber sealing ring. The storage bottle body can be made of glass. The first motor 6 is fixed to the first motor frame 5, which is fixedly installed to the perforated plate 18 via a first extension frame 4. The fixed bracket 20 is also fixedly installed to the perforated plate 18, and is fixed directly below the first extension frame 4. The output shaft of the first motor 6 is fixedly connected to the connecting frame 8. Both ends of the connecting frame 8 are connected to the rotating frame 16 via bolt 7. The end of the rotating frame 16 away from the connecting frame 8 is connected to the rotating clamp 10 via bolt 11. The storage bottle body of the storage grinding bottle 9 is fixedly assembled in the rotating clamp 10. The motor drives the connecting frame 8 and the rotating frame 16 to rotate, thus controlling the storage grinding bottle 9. The discharge port of the storage bottle body is connected to the grinding head 12 via a sealing rubber ring. The grinding head 12 is limited and fixed by a fixing clamp 13. The fixing clamp 13 is fixedly installed on the outer periphery of the grinding head 12 by bolts, and the position of the fixing clamp 13 is fixed by a fixing bracket 20. Specifically, one side of the fixing clamp 13 is fixedly connected to a sleeve 19, and the other end of the sleeve 19 is fixedly connected to the fixing bracket 20. The fixing clamp 13 fixes the grinding head 12. When the first motor 6 drives the storage grinding bottle 9 to rotate, the storage bottle body and the grinding head 12 rotate relative to each other, achieving grinding and discharging.

[0043] In the above embodiments, the sealing rubber ring cooperates with the storage bottle body to prevent moisture from entering, keeping the solid granular seasoning dry and solving the problem that solid ingredients are prone to moisture and deterioration in the prior art.

[0044] In the above embodiment, one end of the rotating frame 16 is connected to the rotating clamp 10 via bolt 2 11, and the other end is connected to the motor output shaft via the connecting frame 8, realizing the linkage between the storage bottle body and the first motor 6, which can support the storage and grinding bottle 9 and transmit power. The first motor 6 is fixed to the perforated plate 18 via the first motor frame 5 and the first extension frame 4, and the motor output shaft is connected to the connecting frame 8 via a set screw, which is used to drive the storage bottle body to rotate. After the solid granular seasoning is ground by the storage and grinding mechanism 1 with the above structure, seasoning powder is obtained.

[0045] In the above embodiment, the grinding head 12 and the storage bottle are fixed by the fixing clamp 13 and the rotating clamp 10, respectively, which facilitates the disassembly and replacement of the solid granular seasoning. During operation, if it is necessary to replace the solid granular seasoning, simply loosen the bolts on the fixing clamp 13 and the rotating clamp 10, remove the storage grinding bottle 9, and reinstall it in its original position after replacing the solid granular seasoning.

[0046] In one specific embodiment, the grinding head 12 includes a grinding core, an inner grinding ring, a outer shell, and a fine-tuning mechanism, used to grind solid particles into powder. The grinding head 12 is connected to the storage bottle body and is fixed to the fixed bracket 20 by a fixing clamp 13. The grinding head 12 and the fixing clamp 13 are connected by bolts 14. The fixing clamp 13 is fixed to the fixed bracket 20 by bolts and sleeves 19. The fixed bracket 20 is fixedly connected by bolts.

[0047] The tooth profile of the grinding core is further optimized as follows:

[0048] Logarithmic spiral bevel gears are based on the logarithmic polar equation r = ae bθ ; r is the distance from the point to the axis of rotation, θ is the rotation angle, and a and b are constants. The logarithmic function of the two-dimensional plane is projected onto the surface of the cone using the cone's axis of rotation as the axis of rotation, generating a logarithmic spiral in space. This spiral is then used as the centerline of the gear teeth.

[0049] The axis of the cone coincides with the Z-axis of the coordinate system. The equation of the logarithmic spiral in spatial coordinates is as follows:

[0050]

[0051] In the formula, m = sinαcotβ, α is the half-cone angle, φ is a variable (rotation angle in the xoy plane), and α, β, and r0 are constants. The parametric equation for the tooth profile of the logarithmic spiral bevel gear is:

[0052]

[0053] After determining the centerline, an involute logarithmic spiral bevel gear is obtained by using the involute gear tooth profile plus the above-mentioned logarithmic spiral as the guide line; where the number of teeth is Z and the angle is 360° / Z.

[0054] In one specific embodiment, in order to accurately deliver the ground seasoning powder to the feeding mechanism 3, a funnel mechanism is provided below the storage and grinding mechanism 1. The funnel mechanism includes a funnel 25 and a funnel support 24. The funnel support 24 is fixed to the perforated plate 18 with bolts, and then the funnel 25 is installed on the funnel support 24. When multiple storage and grinding mechanisms 1 are installed at the same time, the seasoning powder ground at different positions can be collected on the measuring spoon 43 through the funnel 25.

[0055] During the process of collecting the ground seasoning powder onto the measuring spoon 43, it is often necessary to precisely control the amount of seasoning powder. Therefore, a weighing mechanism 2 is added between the storage and grinding mechanism 1 and the feeding mechanism 3.

[0056] In one specific embodiment, such as Figure 3As shown, the weighing mechanism 2 includes a weighing plate 32, a pressure sensor 31, a rotating component 26, and a second motor 23. Specifically, the second motor 23 is fixed on a second motor frame 22, which is fixedly connected to the perforated plate 18 via a second extension frame 21. The output shaft of the second motor 23 is connected to the rotating component 26. A base plate 29 is fixedly mounted on the rotating component 26. The weighing plate 32 is fixed above the base plate 29, and a pressure sensor 31 and a pad 30 are placed between them. A funnel 25 is located below the weighing plate 32 and is fixedly mounted on the perforated plate 18 via a funnel bracket 24. The second motor 23 drives the rotating component 26 to rotate, causing the weighing plate 32 to tilt 90°, allowing the solid granular seasoning on it to fall into the funnel 25 below, and then into the feeding mechanism 3 through the funnel 25.

[0057] In the above structure, specifically, two rotating parts 26 are fixed at both ends of the bottom of the base plate 29. One rotating part 26 is connected to the second motor 23, and the other rotating part 26 is rotatably connected to the first bearing seat 28 through the first bearing 27. The first bearing seat 28 is fixedly connected to the perforated plate 18. The two rotating parts 26 are at the same height and have the same front-to-back distance from the perforated plate 18. The base plate 29 is fixed above them to provide support and rotational driving force for the weighing plate 32. A pad 30 is fixed in the center above the base plate 29, and a pressure sensor 31 is installed above the pad 30. The weighing plate 32 is fixed to the pressure sensor 31 to weigh the solid granular seasoning. The length of the weighing plate 32 covers the two storage and grinding mechanisms 1, and can collect the solid granular seasoning that falls from the two grinding heads 12. After weighing, it rotates 90° under the drive of the second motor 23 to pour the solid granular seasoning into the funnel 25 at the bottom. It should be understood that the funnel 25 is a funnel-shaped structure with an opening at the top and bottom. The opening at the top covers the entire weighing plate 32, so that the solid granular seasoning will not scatter outside the area when it falls. The opening at the bottom of the funnel 25 is narrowed to collect the solid granular seasoning into the measuring spoon 43 of the feeding mechanism 3.

[0058] In one specific embodiment, during the installation of the weighing mechanism 2, the first bearing seat 28 is first fixed to the orifice plate 18 with cylindrical bolts, and the first bearing 27 is installed on the first bearing seat 28; then the second motor 23 is installed on the second motor frame 22, and the second extension frame 21 is used to fix the second motor frame 22 to the orifice plate 18; then the rotating parts 26 are respectively installed on the second motor 23 and the first bearing 27, and the base plate 29 is fixed to the two rotating parts 26 as a whole with screws; finally, the pad 30 and the pressure sensor 31 are connected together with AB glue and fixed to the base plate 29 with AB glue, and the food-grade weighing plate 32 is fixed to the pressure sensor 31 with AB glue.

[0059] It should be understood that in practical applications, both the first motor 6 and the second motor 23 are connected to the control center, which controls their operation so that the required amount of solid granular seasoning can be ground and weighed.

[0060] In one specific embodiment, such as Figure 4 As shown, the feeding mechanism 3 includes a base 39, a rotary table 35, a fourth motor 38, a coupling 37, a rocker arm 36, a third motor frame 34, a third motor 33, a rotating shaft 42, a second bearing seat 44, a second bearing 45, and a measuring spoon 43. The base 39 is fixed to a horizontal base and has a hollow, downward-facing U-shaped structure. The fourth motor 38 is fixed inside the base 39, and its output shaft passes through the base 39 and connects to the rotary table 35 above it. The third motor 33 and the rocker arm 36 are fixed on the rotary table 35, and the second bearing seat 44 is located above the rocker arm 36. The output shaft of the third motor 33 is connected to the rotating shaft 42, which rotates on the second bearing seat 44 via the second bearing 45. The rotating shaft 42 extends coaxially with the rocker arm 36, and the end of the rotating shaft 42 away from the third motor 33 is fixedly connected to the measuring spoon 43. Furthermore, couplings 37 are connected to the output shafts of both the third motor 33 and the fourth motor 38.

[0061] During installation, first, fix the mechanism base 39 onto the horizontal base, then install the rotary table 35 onto the mechanism base 39. Next, install the second bearing housing 44 onto the rocker arm 36 of the rotary table 35, and install the second bearing 45 inside the second bearing housing 44. Then, install the third motor 33 onto the third motor frame 34, and then install the third motor frame 34 onto the rotary table 35. Simultaneously, pass the rotating shaft 42 through the second bearing 45 and connect it to the motor output shaft of the third motor 33 using a coupling 37. Next, secure the measuring spoon 43 to the rotating shaft 42 with a rubber band. Finally, push the fourth motor 38 into the bottom of the support and fix it to the horizontal base with screws. Then, connect the motor output shaft of the fourth motor 38 to the rotating shaft of the rotary table 35 using a coupling 37, completing the installation of the entire feeding mechanism 3.

[0062] This utility model also proposes a cooking machine, including a cooking execution device, a control system, and a solid particle storage, grinding, and spraying device. The cooking execution device includes a stove, a stirring mechanism, etc. The solid particle storage, grinding, and spraying device includes a storage and grinding mechanism 1, a weighing mechanism 2, a funnel mechanism, a feeding mechanism 3, and a support base. The solid particle storage, grinding, and spraying device is located on one side of the cooking execution device. The control system includes a PLC terminal for controlling the coordinated operation of the cooking execution device and the solid particle storage, grinding, and spraying device.

[0063] like Figure 5As shown, the PLC terminal sends a command to the cooking machine, firstly controlling the first motor 6 to run. The first motor 6 transmits power through the rotating frame 16, causing the storage bottle 9 in the grinding bottle to rotate. Since the grinding head 12 is fixed on the fixed bracket 20, the storage bottle and the grinding head 12 rotate relative to each other. The solid granular seasoning moves downward under the action of gravity and is crushed by the grinding core and inner grinding ring in the grinding head 12. The crushed seasoning powder falls onto the weighing plate 32 through the grinding head 12. The pressure sensor 31 feeds back the weighing information to the PLC terminal in real time. When the weighed mass reaches the preset threshold, the PLC terminal controls the first motor 6 to stop. The PLC terminal stops the rotation and simultaneously controls the second motor 23 to run. The second motor 23 drives the weighing plate 32 to rotate and tilt, introducing the seasoning powder into the funnel 25. The seasoning powder is collected in the measuring spoon 43 through the funnel 25. At this time, the PLC terminal controls the second motor 23 to run in reverse, returning to the initial position, and controls the fourth motor 38 to run, rotating the measuring spoon 43 above the stove. When the measuring spoon 43 reaches the top of the stove, the PLC terminal controls the third motor 33 to run, causing the measuring spoon 43 to flip and pour the seasoning powder into the stove. After completing the above operations, the PLC terminal controls the third motor 33 and the fourth motor 38 to return to the initial position. 。
