Description

Technical Field

[0001] The invention relates to the technical field of ingredient placement, in particular to a solid particle storage, grinding and spraying device. Background Art

[0002] As the pace of modern life accelerates, people's demand for convenient and efficient kitchen cooking equipment is increasing. As a device that can automatically complete cooking tasks, cooking machines have attracted widespread attention because they can free people's hands and quickly make delicious dishes. Among the many key components of cooking machines, the solid ingredient delivery device is particularly important. It is responsible for accurately delivering solid seasonings such as salt, sugar, and MSG during the cooking process, which directly affects the final taste of the dish.

[0003] However, the existing solid ingredient delivery device has a significant defect: the solid ingredients in the device are easily affected by moisture and deteriorate. The moisture in the air will gradually penetrate into the seasoning storage area, causing the solid seasoning to absorb moisture and agglomerate, which not only affects its fluidity, but may also breed bacteria and mold, thereby affecting the quality and safety of the seasoning. Once the damp and deteriorated seasoning is added to the dish, it will not only destroy the taste of the dish, but may also pose a potential threat to the health of consumers. In addition, the moisture problem of solid ingredients also limits their long-term storage capacity in the cooking machine. Users need to frequently change seasonings, which increases the cost of use and the complexity of operation, and reduces the convenience and practicality of the cooking machine.

[0004] Therefore, how to effectively solve the problem of moisture-proofing of solid ingredients, extend the shelf life of seasonings, and at the same time ensure their accuracy and safety during the cooking process has become a key issue that needs to be urgently solved in the current field of cooking machine technology. Summary of the invention

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

[0006] To achieve the above object, the present invention provides a solid particle storage, grinding and spraying device, comprising:

[0007] A support base, comprising a horizontal base and a vertical orifice plate fixed on the horizontal base;

[0008] A storage and grinding mechanism, the storage and grinding mechanism comprises a first motor fixed on the orifice plate, a storage and grinding bottle connected to the motor output shaft of the first motor, the storage bottle body of the storage and grinding bottle is open downward and is rotatably matched with a grinding head, and the grinding head is positioned on the orifice plate through a fixed bracket; the first motor drives the storage bottle body to rotate relative to the grinding head to achieve grinding of solid particle condiments;

[0009] A weighing mechanism is disposed below the grinding head, comprising a weighing plate, a pressure sensor disposed at the bottom of the weighing plate, and a second motor fixed on the orifice plate for driving the weighing plate to flip sideways;

[0010] A funnel mechanism, comprising a funnel and a funnel bracket for fixing the funnel, wherein the funnel is arranged directly below the weighing plate, and the funnel bracket is fixedly connected to the orifice plate;

[0011] The feeding mechanism is arranged below the funnel mechanism, and comprises a measuring spoon, a fourth motor for driving the spoon to move horizontally, and a third motor for driving the measuring spoon to flip.

[0012] In some optional schemes of the present invention, the storage bottle body of the storage grinding bottle is detachably fixed in a set of rotating clamps, and the rotating clamps are transmission-connected to the first motor through a connecting frame and are driven to rotate by the first motor.

[0013] In some optional solutions of the present invention, the grinding head is detachably fixed in a set of fixing clamps, and the fixing clamps are fixedly connected to the orifice plate via a fixing bracket.

[0014] In some optional schemes of the present invention, the grinding head includes a grinding core, a grinding inner ring, an outer shell and a fine-tuning mechanism, and is used to grind solid particles into powder.

[0015] In some optional solutions of the present invention, a logarithmic conic spiral structure is distributed on the grinding core of the grinding head, and the shape of the logarithmic conic spiral structure is determined by the arc of the logarithmic conic spiral line and its normal plane;

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

[0017]

[0018] Where t is the parameter of the logarithmic conic spiral, and t∈[t1,t2], m g is a parameter related to the spiral radius of the logarithmic conic spiral, n g is a parameter related to the pitch of the logarithmic conic helix.

[0019] According to the equation of the logarithmic conic spiral, a center line can be obtained along the direction of its normal vector. Taking the arc as the scanning section, the center line as the scanning line, and the logarithmic conic spiral as the guide 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 the grinding efficiency and accuracy, ensure the uniform particle size of the ground solid particles, and avoid uneven feeding due to different particle sizes.

[0021] In some alternative embodiments of the present invention, a plurality of storage and grinding mechanisms are arranged at intervals transversely along the orifice plate, and each storage and grinding mechanism corresponds to a kind of fixed solid particle condiment. It can store and grind multiple solid particle condiments simultaneously to meet different cooking requirements. The design of the device has good expandability, and the number of storage and grinding mechanisms can be increased or decreased according to actual needs to adapt to stir-fry machines of different specifications.

[0022] In some alternative embodiments of the present invention, the weighing mechanism further includes a rotating member and a bottom plate. The weighing plate is mounted on the bottom plate through a pressure sensor and a cushion block, and the second motor drives the rotating member to drive the weighing plate to turn over. The weighing mechanism adopts a combination of a pressure sensor and a rotating member, which can real-time feedback the weighing information and accurately control the feeding amount of the solid particle condiment through the control system to ensure the taste consistency of the dish.

[0023] In some alternative embodiments of the present invention, the feeding mechanism further includes a rotating table. The measuring spoon is connected to the third motor through a rotating shaft, and the fourth motor drives the rotating table to move the measuring spoon to the target position.

[0024] In some alternative embodiments of the present invention, a plurality of ventilation holes are opened on the orifice plate. The opening of a plurality of ventilation holes on the orifice plate not only ensures the ventilation inside the device, but also prevents the moisture in the air from accumulating inside the device, further enhancing the moisture-proof effect.

[0025] Furthermore, the storage bottle body and the grinding head of the storage and grinding bottle are detachably connected and sealed by a rubber sealing ring. Both the storage bottle body and the grinding head of the storage and grinding bottle adopt a detachable fixing method, which is convenient for users to replace the solid particle condiment or clean the grinding head, reducing the maintenance cost and operation difficulty of the equipment. By setting a rubber sealing ring between the storage bottle body and the grinding head of the storage and grinding bottle, it can effectively prevent the moisture in the air from penetrating into the condiment storage area, thus avoiding the solid particle condiment from absorbing moisture and caking, solving the problem that solid ingredients are prone to moisture and deterioration in the prior art, and extending the storage period of the solid particle condiment.

[0026] The present invention also provides a stir-fry machine, including a stir-fry execution device, a control system, and a solid particle storage, grinding, and spraying device; the solid particle storage, grinding, and spraying device adopts the solid particle storage, grinding, and spraying device described in any one of the above; the stir-fry execution device includes a cooking stove and a stirring mechanism, and the control system is communicatively connected to the storage and grinding mechanism, the weighing mechanism, the feeding mechanism, and the stir-fry execution device in the solid particle storage, grinding, and spraying device for coordinating the operation timing of each mechanism.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Refer to Figures 1 to 5 As shown, the present invention provides a solid particle storage, grinding, and spraying device, which includes a storage and grinding mechanism 1, a weighing mechanism 2, a funnel mechanism, a feeding mechanism 3, and a support seat for fixing the above mechanisms. Specifically, the support seat includes a horizontal base and a perforated plate 18 vertically fixed on the horizontal base. The perforated plate 18 is vertically arranged and is used to install the storage and grinding mechanism 1 and the weighing mechanism 2. The feeding mechanism 3 is fixed on the horizontal base. A plurality of ventilation holes are provided on the perforated plate 18.

[0040] In a specific embodiment, a plurality of 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 particle seasonings, such as salt, sugar, monosodium glutamate, pepper, etc.

[0041] In this embodiment, two storage and grinding mechanisms 1 are taken as an example for description. As Figure 1 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. The two storage and grinding bottles 9 store common salt and sugar respectively. Each storage and grinding mechanism 1 is fixedly installed on the perforated plate 18 through a first extension frame 4, and the installation positions of the storage and grinding mechanisms 1 are determined according to needs.

[0042] In a specific embodiment, as Figure 2As shown in the figure, the storage and grinding mechanism 1 includes a first motor bracket 5, a first motor 6, a connecting bracket 8, a rotating bracket 16, a storage and grinding bottle 9, a rotating clamp 10, a fixed clamp 13, and a fixed bracket 20. Among them, the storage and grinding bottle 9 includes a storage bottle body and a grinding head 12. The storage bottle body and the grinding head 12 are rotationally matched and sealed by a rubber sealing ring. The storage bottle body can be made of a glass bottle. The first motor 6 is fixed on the first motor bracket 5. The first motor bracket 5 is fixedly installed on the orifice plate 18 through a first extension bracket 4. The fixed bracket 20 is also fixedly installed on the orifice plate 18, and the fixed bracket 20 is fixed directly below the first extension bracket 4. The motor output shaft of the first motor 6 is fixedly connected to the connecting bracket 8. Both ends of the connecting bracket 8 are connected to the rotating bracket 16 through bolts 7. One end of the rotating bracket 16 away from the connecting bracket 8 is connected to the rotating clamp 10 through a bolt 11. The storage bottle body of the storage and grinding bottle 9 is fixedly assembled in the rotating clamp 10. By driving the connecting bracket 8 and the rotating bracket 16 to rotate through the motor, the control of the storage and grinding bottle 9 is realized. The discharge port of the storage bottle body is connected to the grinding head 12 through a sealing rubber ring. The grinding head 12 is then limited and fixed by the fixed clamp 13. The fixed clamp 13 is fixedly installed on the outer peripheral side of the grinding head 12 through bolts, and then the position of the fixed clamp 13 is fixed by the fixed bracket 20. Specifically, one side clamp of the fixed clamp 13 is fixedly connected to a sleeve 19, and the other end of the sleeve 19 is fixedly connected to the fixed bracket 20. The fixing of the grinding head 12 is achieved through the fixed clamp 13. When the first motor 6 drives the storage and grinding bottle 9 to rotate, the storage bottle body and the grinding head 12 rotate relative to each other, realizing grinding and discharging.

[0043] In the above embodiment, the sealing rubber ring cooperates with the storage bottle body to prevent water vapor from entering, keep the solid particle condiment dry, and solve the problem that the solid ingredients in the prior art are prone to moisture and deterioration.

[0044] In the above embodiment, one end of the rotating bracket 16 is connected to the rotating clamp 10 through a bolt 11, and the other end is connected to the motor output shaft through the connecting bracket 8, realizing the linkage of the storage bottle body and the first motor 6, being able to support the storage and grinding bottle 9 and transmit power. The first motor 6 is fixed to the orifice plate 18 through the first motor bracket 5 and the first extension bracket 4. The motor output shaft is connected to the connecting bracket 8 through a set screw, used to drive the storage bottle body to rotate. After the solid particle condiment is ground by the storage and grinding mechanism 1 with the above structure, condiment powder is obtained.

[0045] In the above embodiment, the grinding head 12 and the storage bottle body are fixed by the fixed clamp 13 and the rotating clamp 10 respectively, which is convenient for disassembling and replacing the solid particle condiment. During operation, if it is necessary to replace the new solid particle condiment, only need to loosen the bolts on the fixed clamp 13 and the rotating clamp 10, and remove the storage and grinding bottle 9. After replacing the solid particle condiment, install it in the original position.

[0046] In a specific embodiment, the grinding head 12 includes a grinding core, a grinding inner ring, a housing, and a fine-tuning mechanism for grinding solid particles into powder. The grinding head 12 is connected to the storage bottle body. The grinding head 12 is fixed to the fixed bracket 20 with a fixed clamp 13. The grinding head 12 and the fixed clamp 13 are connected with bolt three 14. The fixed clamp 13 and the fixed bracket 20 are fixed with bolts and a sleeve 19. The fixed bracket 20 is fixedly connected by bolts.

[0047] For a further optimized solution, the tooth profile of the grinding core is as follows:

[0048] The logarithmic spiral bevel gear is based on the polar coordinate equation of the logarithm 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. Taking the axis of the cone as the axis of rotation, the logarithmic function in the two-dimensional plane is projected onto the curved surface of the cone to generate a logarithmic spiral line in space, and this spiral line is used as the center line of the tooth.

[0049] The axis of the cone coincides with the Z-axis of the coordinate system. The equation of the logarithmic spiral line in the space coordinates:

[0050]

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

[0052]

[0053] After determining the center line, an involute logarithmic spiral bevel gear is obtained with the involute gear tooth profile plus the above logarithmic spiral line as the guiding line; where the number of teeth is Z and the angle is 360° / Z.

[0054] In a specific embodiment, in order to accurately convey the ground condiment 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 bracket 24. The funnel bracket 24 is fixed to the hole plate 18 with bolts, and then the funnel 25 is installed on the funnel bracket 24. When multiple storage and grinding mechanisms 1 are installed in the device, the ground condiment powders at different positions can be collected on the measuring spoon 43 through the funnel 25.

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

[0056] In a specific embodiment, as Figure 3As shown in the figure, the weighing mechanism 2 includes a weighing plate 32, a pressure sensor 31, a rotating member 26, and a second motor 23. Specifically, the second motor 23 is fixed on the second motor bracket 22. The second motor bracket 22 is fixedly connected to the orifice plate 18 through a second extension bracket 21. The motor output shaft of the second motor 23 is connected to the rotating member 26. A bottom plate 29 is fixedly installed on the rotating member 26. The weighing plate 32 is fixed above the bottom plate 29, and a pressure sensor 31 and a cushion block 30 are arranged between the two. The funnel 25 is located below the weighing plate 32 and is fixedly installed on the orifice plate 18 through a funnel bracket 24. The second motor 23 drives the rotating member 26 to rotate, driving the weighing plate 32 to turn over by 90°, so that the solid particulate condiment thereon falls into the lower funnel 25 and enters the feeding mechanism 3 through the funnel 25.

[0057] In the above structure, specifically, two rotating members 26 are fixed at both ends of the bottom of the bottom plate 29. One of the rotating members 26 is connected to the second motor 23, and the other rotating member 26 is rotatably connected to the first bearing seat 28 through a first bearing 27. Among them, the first bearing seat 28 is fixedly connected to the orifice plate 18. The two rotating members 26 have the same height and the same front-back distance from the orifice plate 18. The bottom plate 29 is fixed above the two, providing support and rotational driving force for the weighing plate 32. A cushion block 30 is fixed in the center above the bottom plate 29, and a pressure sensor 31 is installed above the cushion block 30. The weighing plate 32 is fixed on the pressure sensor 31 to realize the weighing of the solid particulate condiment. Among them, the length of the weighing plate 32 covers the two storage and grinding mechanisms 1, and can receive the solid particulate condiments falling from the two grinding heads 12 respectively. After weighing, it rotates 90° under the drive of the second motor 23, and pours the solid particulate condiment into the bottom funnel 25. It should be understood that the funnel 25 is a funnel-shaped structure with openings at the top and bottom. The top opening range covers the entire weighing plate 32, so that the solid particulate condiment will not scatter outside the funnel 25 when falling. The bottom opening of the funnel 25 shrinks, and is used to collect the solid particulate condiment into the measuring spoon 43 of the feeding mechanism 3.

[0058] In a specific embodiment, when installing the weighing mechanism 2, first fix the first bearing seat 28 to the orifice plate 18 with cylinder bolts, and install the first bearing 27 on the first bearing seat 28; then install the second motor 23 on the second motor bracket 22, and then use the second extension bracket 21 to fix the second motor bracket 22 to the orifice plate 18; then install the rotating members 26 on the second motor 23 and the first bearing 27 respectively, and fix the bottom plate 29 to the two rotating members 26 with screws as a whole; finally, connect the cushion block 30 and the pressure sensor 31 together with AB glue and fix them to the bottom plate 29 with AB glue, and fix the food-grade weighing plate 32 to the pressure sensor 31 with AB glue.

[0059] It should be understood that in practical applications, the first motor 6 and the second motor 23 are both connected to a control center, and the operation of the two is controlled by the control center so as to grind and weigh the required amount of solid particulate condiments.

[0060] In a specific embodiment, as Figure 4 shown, the feeding mechanism 3 includes a mechanism base 39, a rotating table 35, a fourth motor 38, a coupling 37, a rocker arm 36, a third motor bracket 34, a third motor 33, a rotating shaft 42, a second bearing seat 44, a second bearing 45, and a measuring spoon 43. Among them, the mechanism base 39 is fixed on a horizontal base. The mechanism base 39 is a U-shaped structure with a hollow interior and an open bottom. The fourth motor 38 is fixed inside the mechanism base 39. Its motor output shaft penetrates through the mechanism base 39 and is connected to the rotating table 35 above the mechanism base 39. The third motor 33 and the rocker arm 36 are fixed on the rotating table 35, and there is a second bearing seat 44 above the rocker arm 36. Among them, the motor output shaft of the third motor 33 is connected to the rotating shaft 42. The rotating shaft 42 rotates on the second bearing seat 44 through the second bearing 45. The rotating shaft 42 extends coaxially with the rocker arm 36. One end of the rotating shaft 42 away from the third motor 33 is fixedly connected to the measuring spoon 43. Further, couplings 37 are connected to the motor output shafts of both the third motor 33 and the fourth motor 38.

[0061] During installation, first fix the mechanism base 39 to the horizontal base, and then install the rotating table 35 on the mechanism base 39. Next, install the second bearing seat 44 on the rocker arm 36 of the rotating table 35, and install the second bearing 45 inside the second bearing seat 44. Then, install the third motor 33 on the third motor bracket 34, and then install the third motor bracket 34 on the rotating table 35. At the same time, pass the rotating shaft 42 through the second bearing 45 and connect it to the motor output shaft of the third motor 33 with a coupling 37. Then tie and fix 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, and then connect the motor output shaft of the fourth motor 38 to the rotating shaft of the rotating table 35 with a coupling 37 to complete the installation of the entire feeding mechanism 3.

[0062] The present invention also proposes a cooking machine, which includes a cooking execution device, a control system, and a solid particulate storage, grinding, and spraying device. The cooking execution device includes a cooking stove, a stirring mechanism, etc. The solid particulate 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 seat. The solid particulate storage, grinding, and spraying device is arranged 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 particulate storage, grinding, and spraying device.

[0063] As Figure 5As shown, commands are sent to the cooking machine through the PLC terminal. First, the first motor 6 is controlled to operate. The first motor 6 transmits power through the rotating frame 16 to drive the storage bottle body in the storage and grinding bottle 9 to rotate. Since the grinding head 12 is fixed on the fixed bracket 20, relative rotation occurs between the storage bottle body and the grinding head 12. The solid particle seasonings move downward under the action of gravity and are crushed by the grinding core and the 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 weighing mass reaches the preset threshold, the PLC terminal controls the first motor 6 to stop rotating. At the same time, the second motor 23 is controlled to operate. The second motor 23 drives the weighing plate 32 to rotate and turn over, pouring 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 the reverse direction and return to the initial position, and controls the fourth motor 38 to operate to rotate the measuring spoon 43 above the cooking stove. When the measuring spoon 43 reaches above the cooking stove, the PLC terminal controls the third motor 33 to operate to turn the measuring spoon 43 over, pouring the seasoning powder into the cooking stove. After the above operations are completed, the PLC terminal controls the third motor 33 and the fourth motor 38 to return to the initial position.
