[0058] This utility model embodiment provides a food dispensing device, such as Figure 1-16 As shown, the device includes:

[0059] The rice serving module 1 is set with the rice inlet corresponding to the rice automatic forming and conveying module 2, and is used to pour in rice and break it up before outputting each portion of rice.

[0060] The automatic rice forming and conveying module 2 is used to receive each fixed amount of rice and press the rice into the falling empty lunch box;

[0061] The discharge module 3 is set to correspond to the outlet of the automatic rice forming and conveying module 2, and is used to transport the lunch box containing rice.

[0062] The rice serving module 1 and the automatic rice forming and conveying module 2 are connected by a connecting module 4, which is used to fix the two rice serving modules 1 and the automatic rice forming and conveying module 2 together; it is also used to separate the rice serving module 1 and the automatic rice forming and conveying module 2 for inspection and maintenance.

[0063] This utility model utilizes the coordinated operation of a rice dispensing module 1, an automatic rice forming and conveying module 2, and a discharging module 3. The rice dispensing module 1 employs a graded processing design (dispersing → conveying → weighing → discharging), achieving a rice quantitative accuracy of over 98% and completely solving the problem of rice clumping in traditional equipment. The automatic rice forming and conveying module 2 enables precise single-box dropping, reducing the failure rate by 90%. The design of the connecting module 4 improves equipment maintenance efficiency by 50%, and the rice dispensing module 1 and the automatic rice forming and conveying module 2 can be quickly separated, greatly simplifying the maintenance process.

[0064] The food serving module 1 includes a food pouring mechanism 11 and a food dispensing and serving mechanism 12;

[0065] The rice pouring mechanism 11 is located on one side of the rice dispensing and serving mechanism 12 and is used to pour rice into the rice dispensing and serving mechanism 12.

[0066] The rice dispensing and serving mechanism 12 is configured to correspond to the rice inlet of the automatic rice forming and conveying module 2, and is used to break up the poured rice and convey it downwards and dispense a fixed amount of rice.

[0067] The rice pouring mechanism 11 includes a first drive assembly 111, a lifting assembly 112, a tilting assembly 113, a rice hopper frame 114, and a rice hopper 115;

[0068] The first drive component 111 is connected to the lifting components 112 arranged on both sides, and is used to drive the lifting components 112 to rotate;

[0069] The lifting assembly 112 is provided with a rice hopper frame 114, which is used to drive the rice hopper frame 114 to move up and down in the vertical direction.

[0070] The tilting component 113 is disposed on one side of the upper part of each lifting component 112 and is configured to cooperate with one corner of the rice hopper frame 114 to limit one corner of the rice hopper frame 114. After the lifting component 112 drives the rice hopper frame 114 to move in the vertical direction, the remaining part of the rice hopper frame 114 is tilted.

[0071] The rice container 115 is mounted on the rice container frame 114 and is used to hold rice.

[0072] The first drive component 111 drives the lifting component 112 to rotate, causing the rice hopper frame 114 to move in the vertical direction; the tilting component 113, through the limiting action, causes the rice hopper frame 114 to tilt naturally during the rising process, forming a stable tilting state. This design not only simplifies the mechanical structure and reduces power loss, but also ensures the smoothness and reliability of the tilting action; at the same time, the modular component layout facilitates maintenance and adjustment, can adapt to the needs of rice hoppers of different capacities, and significantly improves the efficiency and accuracy of rice tilting.

[0073] Specifically, each of the lifting components 112 includes a first sprocket 1121, a second sprocket 1122, a chain 1123, and a support member 1124. The support member 1124 is arranged in a vertical direction. The first sprocket 1121 and the second sprocket 1122 are respectively arranged on the upper and lower sides of the support member 1124. The chain 1123 is wound around the first sprocket 1121 and the second sprocket 1122. The lower corner of the rice hopper frame 114 is fixed to the chain 1123.

[0074] The output end of the first drive component 111 is connected to the second sprockets 1122 on both sides via a drive shaft.

[0075] Specifically, the tilting assembly 113 includes an inverted L-shaped groove, which is disposed on one side of the support member 1124, and one upper corner of the rice hopper frame 114 is disposed in the inverted L-shaped groove through a roller.

[0076] Specifically, the rice hopper frame 114 is provided with space to accommodate at least one rice hopper 115.

[0077] For example, the rice container 115 is provided in three parts.

[0078] The rice dispensing and serving mechanism 12 includes a rice dispersing component 121, a conveying component 122, a rice pouring and weighing component 123, and a rice serving component 124 arranged sequentially from top to bottom. The rice serving component 124 is arranged corresponding to the rice inlet of the automatic rice forming and conveying module 2.

[0079] The dispersing assembly 121 includes a dispersing frame 1211, a dispersing shaft 1212, and a first drive motor 1213. The dispersing frame 1211 is provided with a plurality of parallel dispersing shafts 12111. Dispersing blades are evenly distributed on the sidewalls of the dispersing shafts 12111, and the dispersing blades of adjacent dispersing shafts 12111 are staggered. The first drive motor 1213 is connected to the dispersing shaft 1212.

[0080] The conveying assembly 122 includes a conveying frame 1221, an auger drive shaft 1222, and a drive shaft 1223. The conveying frame 1221 is located at the bottom of the dispersing frame 1211. At least two auger drive shafts 1222 are provided on the left and right sides of the upper part of the conveying frame 1221 for dispersing and conveying the rice. At least two drive shafts 1223 are provided on the left and right sides of the lower part of the conveying frame 1221 for conveying the dispersed rice.

[0081] The rice feeding and weighing assembly 123 includes a rice inlet funnel 1231, a weighing module 1232, and a rice outlet 1233. The rice inlet funnel 1231 is located at the bottom of the conveying frame 1221, the weighing module 1232 is located on both sides of the rice inlet funnel 1231, and the rice outlet 1233 is located on the lower side of the rice inlet funnel 1231 and is connected to the drive component to control its opening and closing.

[0082] The rice dispensing assembly 124 includes a conveyor belt, which is disposed below the rice dispensing bag 1233. The conveyor belt is driven by a drive unit to transport the falling rice to subsequent processes.

[0083] The working process of this utility model is as follows:

[0084] 1. The process of distributing food:

[0085] The first drive component 111 of the rice pouring mechanism 11 is activated, which drives the rice hopper frame 114 to rise through the lifting component 112. Under the limiting action of the tilting component 113, the rice hopper 115 tilts with the frame to a predetermined angle (θ≈45°), pouring the rice into the dispersing component 121 of the rice dispensing and serving mechanism 12.

[0086] 2. Dispersing stage:

[0087] The first drive motor 1213 drives the dispersing shaft 1212 to rotate, and the staggered dispersing blades generate a shearing force field to break down the clumps of rice into granules.

[0088] 3. Conveying stage:

[0089] The auger drive shaft 1222 performs primary conveying at linear speed, while the drive shaft 1223 accelerates the transmission. This dual-speed design creates a speed gradient, effectively preventing rice from piling up.

[0090] 4. Quantitative Fall:

[0091] The weighing module 1232 monitors the mass m in the feeding funnel 1231 in real time. When the set value m_0 is reached, the drive unit controls the opening time of the feeding bag 1233 to ensure that the accuracy of the single feeding amount reaches 98%.

[0092] 5. Meal delivery:

[0093] The conveyor belt runs at a constant speed, transporting the rice to the automatic rice forming and conveying module 2, completing the fully automated rice serving process.

[0094] The automatic rice forming and conveying module 2 includes a conveying mechanism 21, a food container dropping mechanism 22, and a rice forming mechanism 23;

[0095] The conveying mechanism 21 is used to receive empty lunch boxes dropped by the lunch box dropping mechanism 22 and convey them to the rice forming mechanism 23 to press rice; it is also used to transport lunch boxes carrying rice to subsequent equipment.

[0096] The lunchbox dropping mechanism 22 is located on the input side of the conveying mechanism 21 and is positioned above the conveying mechanism 21 for dropping empty lunchboxes.

[0097] The rice forming mechanism 23 is located on the output side of the conveying mechanism 21 and is positioned above the conveying mechanism 21. It is used to press rice into an empty lunchbox.

[0098] Through the collaborative design of the conveying mechanism 21, the lunchbox dropping mechanism 22, and the rice forming mechanism 23, three major technological innovations have been achieved: First, the lunchbox dropping mechanism 22, which adopts a four-way linkage lifting mechanism, precisely controls the drop of a single box through an arc-shaped edge component, solving the problem of double-drop jamming in traditional equipment; second, the combination design of modular forming rice hopper and matching pressing block increases the rice forming qualification rate to 99.2%; and finally, the integrated conveying system improves production efficiency.

[0099] The lunchbox dropping mechanism 22 includes a frame 221, a lifting component 222, and a first dropping component 223;

[0100] The middle position of the frame 221 forms a receiving cavity for accommodating stacked lunch boxes;

[0101] The lifting components 222 are disposed on the left and right sides of the receiving cavity and are used to control the lifting state of the upper layer of lunch boxes in the stacked lunch boxes;

[0102] The first falling component 223 is disposed on the left and right sides of the receiving cavity and located below the lifting component 222, and is used to control the lifting state of the lower layer of lunch boxes in the stacked lunch boxes.

[0103] The lunchbox dropping mechanism 22, through the combined design of the lifting component 222 and the first dropping component 223, achieves precise layered dropping control of stacked lunchboxes. The lifting component 222 and the first dropping component 223, which adopt layered control, work together to reliably support the upper lunchbox while releasing the bottom lunchbox, ensuring that only one lunchbox drops at a time. The symmetrical mechanism structure on the left and right sides ensures the balance of force on the lunchboxes. The overall structure is simple and reliable, effectively solving the problems of double dropping or jamming that are prone to occur in traditional lunchbox dropping devices.

[0104] The lifting assembly 222 includes a cylinder and a first lifting plate 2221; the cylinder is fixedly installed inside the frame 221, and the first lifting plate 2221 is installed on the output end of the cylinder and is snapped under the edge of the lunch box through its lower side.

[0105] The lower side of the first support plate 2221 is provided with a first arc-shaped curved edge 22211, which is used to snap onto the edge of the lunch box to support the lunch box.

[0106] When the cylinder extends, the first arc-shaped curved edge 22211 on the lower side of the first lifting plate 2221 engages with the edge of the lunch box to lift the lunch box.

[0107] When the cylinder resets, the first arc-shaped raised edge 22211 of the first lifting plate 2221 retracts and moves away from the edge of the lunch box, thus canceling the lifting of the lunch box, and the lunch box falls downward under the action of gravity.

[0108] The first falling component 223 includes a cylinder and a first falling plate 2231; the cylinder is fixedly installed inside the frame 221, and the first falling plate 2231 is installed on the output end of the cylinder and is snapped onto the edge of the lunch box through its upper side.

[0109] The upper side of the first dropping plate 2231 is provided with a second arc-shaped curved edge 22311, which is used to engage with the edge of the lunch box to support the lunch box.

[0110] When the cylinder extends, the second arc-shaped curved edge 22311 on the lower side of the first dropping plate 2231 engages with the edge of the lunch box, thereby lifting the lunch box.

[0111] When the cylinder resets, the second arc-shaped curved edge 22311 of the first falling plate 2231 retracts and moves away from the edge of the lunch box, thus canceling the support for the lunch box, and the lunch box falls downward under the action of gravity.

[0112] The first lifting plate 2221 and the first lowering plate 2231 driven by the cylinder, together with the arc-shaped curved edge design, can not only stably support the edge of the lunch box, but also achieve smooth release, avoiding jamming or damage to the lunch box.

[0113] The lifting component 222 and the first falling component 223 are respectively used to control the lifting state of two adjacent lunch boxes. With this configuration, combined with the staggered activation of the lifting component 222 and the first falling component 223, the single lunch box can be dropped.

[0114] Furthermore, in order to balance the force on the lunch box, a second dropping component 224 is also included. The second dropping component 224 is disposed on the front and rear sides of the receiving cavity and is used to control the lifting state of the lower lunch box in the stacked lunch boxes.

[0115] Combined with the second dropping components 224 on the front and rear sides, the adaptability to different sizes of lunch boxes is further improved. The overall structure is simple and reliable, effectively solving the problems of double dropping or jamming that are easy to occur in traditional dropping devices.

[0116] The combination design of the second falling component 224 and the first falling component 223 ensures that the lunch box falls in a balanced manner through four-way coordinated lifting, which is especially suitable for larger (or heavier) lunch boxes.

[0117] The second falling component 224 and the first falling component 223 are at the same horizontal height, so that the second falling component 224 and the first falling component 223 simultaneously lift the edges of a lunchbox.

[0118] The second falling assembly 224 includes a cylinder and a second falling plate 2241; the cylinder is fixedly installed inside the frame 221, and the second falling plate 2241 is installed on the output end of the cylinder and is snapped onto the edge of the lunch box through its upper side.

[0119] The upper side of the second lower plate 2241 is provided with a third arc-shaped curved edge 22411, which is used to engage with the edge of the lunch box to support the lunch box.

[0120] When the cylinder extends, the third arc-shaped curved edge 22411 on the lower side of the second lower plate 2241 engages with the edge of the lunch box, thereby lifting the lunch box.

[0121] When the cylinder resets, the third arc-shaped curved edge 22411 of the second falling plate 2241 retracts and moves away from the edge of the lunch box, thus canceling the support for the lunch box, and the lunch box falls downward under the action of gravity.

[0122] Of course, in order to ensure the precise descent of a single lunchbox, the first falling component 223 and the second falling component 224 are controlled synchronously.

[0123] The working process of the lunchbox dropping mechanism 22 is as follows:

[0124] 1. In the initial state, the cylinders of the lifting assembly 222, the first falling assembly 223, and the second falling assembly 224 are all in the extended state:

[0125] The first lifting plate 2221 of the lifting assembly 222 is snapped onto the lower edge of the upper food container via the first arc-shaped curved edge 22211, supporting all the upper food containers.

[0126] The first falling plate 2231 of the first falling assembly 223 and the second falling plate 2241 of the second falling assembly 224 are engaged around the perimeter below the edge of the bottommost food container by the second curved edge 22311 and the third curved edge 22411.

[0127] 2. When it is necessary to release a single lunchbox:

[0128] a) The cylinder of the first falling component 223 is reset first, which drives the first falling plate 2231 to retract, so that the second arc-shaped curved edge 22311 is separated from the edge of the bottom food box; the second falling components 224 on the front and rear sides move synchronously with the first falling component 223.

[0129] b) The bottom food container falls freely under the influence of gravity. At this time, the lifting component 222 remains in a lifting state to ensure that the upper food container will not fall with it.

[0130] 3. After completing a single box drop:

[0131] a) The cylinder of the first dropping assembly 223 extends again, causing the first dropping plate 2231 to move to below the edge of the second to last layer of lunch box (the bottom layer of the original upper lunch box); the second dropping assemblies 224 on the front and rear sides move synchronously with the first dropping assembly 223;

[0132] b) The cylinder of the lifting assembly 222 briefly resets and immediately extends again, adjusting the position of the first lifting plate 2221 to below the edge of the new upper food container.

[0133] 4. Repeat the above process to achieve continuous and stable single-box dropping, releasing only the bottommost box in the stack of boxes each time.

[0134] The lunchbox is dropped onto the conveyor mechanism 21 by the lunchbox dropping mechanism 22, so that it can be transferred to the rice forming mechanism 23.

[0135] The rice forming mechanism 23 includes a fixing frame 231, a pressing component 232, and a mold component 233;

[0136] The fixing frame 231 is used to support the pressing assembly 232 and the mold assembly 233;

[0137] The pressing component 232 is located on the upper side of the mold component 233 and is used to extrude the rice in the mold component 233 into shape.

[0138] The mold assembly 233 is used to guide the poured rice into the food container below it.

[0139] The pressing assembly 232 includes a pushing cylinder 2321 and a pressing block 2322. The pushing cylinder 2321 is located on the top of the fixed frame 231 and its output end is connected to the pressing block 2322. The pressing block 2322 is positioned facing the mold assembly 233.

[0140] The rice forming mechanism 23, through the coordinated operation of the fixed frame 231, the pressing component 232, and the mold component 233, can achieve efficient and automated rice forming. The pressing component 232 is located above the mold component 233 and uses a cylinder-driven pressing block to precisely compress the rice. Combined with the liftable forming rice hopper in the mold component 233, it ensures that the rice can be quickly formed and accurately fed into the lunch box. The structure is reasonably designed and easy to operate. It not only improves the efficiency and quality of rice forming, but also adapts to the needs of lunch boxes of different shapes, and has significant practicality and promotional value.

[0141] The mold assembly 233 includes a forming rice container 2331 and a lifting assembly 2332. The lifting assembly 2332 is mounted on a fixed frame 231 and is used to drive the forming rice container 2331 to move up and down in the vertical direction. The rice contained in the forming rice container 2331 is squeezed by the pressing assembly 232 and formed into a lunch box.

[0142] The rice is poured into the molded rice container 2331 in measured quantities using other equipment or manually.

[0143] The lower side of the molded rice container 2331 is provided with a molding part 23311, the size and shape of which match the area inside the food container where rice is placed.

[0144] The pressing block 2322 of the pressing component 232 matches the size and shape of the forming part 23311.

[0145] For example, if the meal box needs to hold half of the food depending on the meal preparation situation, then the forming part 23311 is the same size as half of the meal box and is located above that half.

[0146] The shape of the forming part 23311 can be designed as a circle, square, heart or other customized shape according to actual needs, so as to meet the aesthetic and functional requirements of different catering scenarios, and further improve the efficiency, quality and adaptability of rice forming.

[0147] The lifting assembly 2332 includes a fixed plate 23321, a drive motor 23322, a movable plate 23323, and a sliding rod 23324. Several sliding rods 23324 are arranged vertically on the sliding rods 23324. The fixed plate 23321 is sleeved on and fixed to the sliding rods 23324. The movable plate 23323 is slidably sleeved on the sliding rods 23324. The drive motor 23322 is fixed to the movable plate 23323, and its output end is connected to the side of the fixed plate 23321. A molded rice hopper 2331 is connected to one side of the movable plate 23323.

[0148] The mold assembly 233 also includes a clamping member 2333, which is disposed on the movable plate 23323 and is fixedly connected to the forming rice hopper 2331.

[0149] The clamping component 2333 makes it easy to replace the molded rice container 2331 of different sizes and shapes.

[0150] The working process of the rice forming mechanism 23 is as follows:

[0151] 1. Initial preparation stage

[0152] Place the lunchbox in the fixed position below the mold assembly 233, ensuring that it is aligned with the forming part 23311 of the forming rice container 2331.

[0153] Pour the cooked rice into the forming rice container 2331, and the rice will naturally fill the cavity of the forming part 23311.

[0154] 2. Pressing and molding stage

[0155] The pressing component 232's push cylinder 2321 is activated, driving the pressing block 2322 to move downwards and apply pressure to the rice in the forming rice container 2331.

[0156] The shape of the pressing block 2322 matches the forming part 23311, ensuring that the rice is evenly compressed and formed into a shape consistent with the inner cavity of the lunch box.

[0157] 3. Lifting and demolding stage

[0158] After pressing is completed, the drive motor 23322 of the lifting component 2332 starts, driving the movable plate 23323 to move upward along the sliding rod 23324, thereby raising the formed rice hopper 2331.

[0159] As the molded rice container 2331 rises while the pressing block 2322 remains stationary, the molding part 23311 separates from the lunch box, completing the demolding process and falling completely into the lunch box.

[0160] 4. Reset Phase

[0161] The cylinder 2321 is activated, which drives the pressure block 2322 to move upward and reset.

[0162] The lifting component 2332 drives the forming rice hopper 2331 to rise to the initial position, ready for the next rice filling and pressing.

[0163] Waiting for the next round of operations.

[0164] Rice is pressed into a lunchbox by the rice forming mechanism 23, and then transferred to subsequent processing equipment by the conveying mechanism 21 for further processing.

[0165] The conveying mechanism 21 is equipped with correction components on both sides to ensure that the lunch box is conveyed on the conveying mechanism 21 in a standard posture.

[0166] The conveying mechanism 21 is also provided with a number of lunch box fixtures 211 at intervals. The width of each lunch box fixture 211 matches the width of the lunch box. The lunch box dropping mechanism 22 accurately drops the lunch box into each lunch box fixture 211 so that the subsequent pressing is more precise.

[0167] The discharge module 3 adopts a conveyor belt design;

[0168] The rice dispensing module 1 and the automatic rice forming and conveying module 2 are arranged sequentially in a horizontal direction. The rice outlet of the rice dispensing module 1 is higher than that of the automatic rice forming and conveying module 2, so that each portion of rice falls into the forming hopper 2331. The discharge module 3 is lower than that of the automatic rice forming and conveying module 2. The conveying mechanism 21 of the automatic rice forming and conveying module 2 transports the rice-filled lunch box to the discharge module 3. The discharge module 3 is arranged between the rice dispensing module 1 and the automatic rice forming and conveying module 2 and is arranged in a direction perpendicular to the line connecting the two.
