Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0041] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, article, or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, article, or device comprising the element.

[0042] The embodiment of the present invention provides an automatic rice forming and conveying device, such as Figure 1-8 As shown, the device includes: a conveying mechanism 1, a lunch box dropping mechanism 2, and a rice forming mechanism 3; the conveying mechanism 1 is used to receive the empty lunch boxes dropped by the lunch box dropping mechanism 2 and transfer them to the rice forming mechanism 3 for pressing rice; and is also used to transport the lunch boxes carrying rice to subsequent equipment;

[0043] The lunch box dropping mechanism 2 is located at the input side of the conveying mechanism 1 and is arranged above the conveying mechanism 1, and is used to drop empty lunch boxes;

[0044] The rice forming mechanism 3 is located at the output side of the conveying mechanism 1 and is arranged above the conveying mechanism 1, and is used to press rice into the empty lunch box.

[0045] The present invention achieves three major technological innovations through the coordinated design of the conveying mechanism 1, the lunch box dropping mechanism 2 and the rice forming mechanism 3: first, the lunch box dropping mechanism 2 with four-way linkage lifting accurately controls the drop of a single box through the arc-shaped warping component, solving the double-drop jamming problem of traditional equipment; second, the combined design of the modular forming rice hopper and the matching pressing blocks increases the rice forming qualification rate to 99.2%; finally, the integrated conveying system improves production efficiency.

[0046] The lunch box dropping mechanism 2 includes a frame 201, a lifting component 202, and a first dropping component 203;

[0047] The middle position of the frame 201 forms a receiving cavity for receiving stacked lunch boxes;

[0048] The lifting components 202 are provided on the left and right sides of the accommodating cavity and are used to control the lifting state of the edge of the upper lunch box in the stacked lunch boxes;

[0049] The first falling components 203 are arranged on the left and right sides of the accommodating cavity and are located below the lifting component 202, and are used to control the lifting state of the edge of the lower lunch box in the stacked lunch boxes.

[0050] The lunch box dropping mechanism 2 realizes precise layered dropping control of the stacked lunch boxes through the combined design of the lifting component 202 and the first dropping component 203; the lifting component 202 with layered control works in conjunction with the first dropping component 203, which can reliably support the upper lunch boxes while releasing the bottom lunch boxes, ensuring that only a single lunch box falls at a time; the symmetrical arrangement of the mechanism structure on the left and right sides ensures the force balance of the lunch boxes, the overall structure is simple and reliable, and effectively solves the double-fall or jamming problems that are prone to occur in traditional box dropping devices.

[0051] The lifting assembly 202 includes a cylinder and a first lifting plate 2021; the cylinder is fixedly arranged in the frame 201, and the first lifting plate 2021 is arranged on the output end of the cylinder and is clamped under the edge of the lunch box through its lower side.

[0052] A first arc-shaped edge 20211 is provided on the lower side of the first lifting plate 2021 for being snapped into place under the edge of the lunch box to lift the lunch box.

[0053] When the cylinder extends, the first curved edge 20211 on the lower side of the first lifting plate 2021 is clamped under the edge of the lunch box to lift the lunch box.

[0054] When the cylinder is reset, the first arc-shaped edge 20211 of the first lifting plate 2021 retreats and leaves below the edge of the lunch box, thereby canceling the support for the lunch box, and the lunch box falls downward under the action of gravity.

[0055] The first drop assembly 203 includes a cylinder and a first drop plate 2031 ; the cylinder is fixedly disposed in the frame 201 , and the first drop plate 2031 is disposed on the output end of the cylinder and is clamped under the edge of the lunch box through its upper side.

[0056] A second arc-shaped edge 20311 is provided on the upper side of the first drop plate 2031 for snapping onto the edge of the lunch box to lift the lunch box.

[0057] When the cylinder extends, the second curved edge 20311 on the lower side of the first drop plate 2031 is clamped under the edge of the lunch box to lift the lunch box.

[0058] When the cylinder is reset, the second arc-shaped edge 20311 of the first drop plate 2031 retreats and leaves below the edge of the lunch box, thereby canceling the support for the lunch box, and the lunch box falls downward under the action of gravity.

[0059] The first lifting plate 2021 and the first dropping plate 2031 driven by the cylinder are combined with the arc-shaped warping edge design to firmly support the edge of the lunch box and achieve smooth release to avoid jamming or damage to the lunch box;

[0060] The lifting component 202 and the first falling component 203 are respectively used to control the lifting state of two adjacent lunch boxes. Such an arrangement, combined with the staggered activation of the lifting component 202 and the first falling component 203, can realize the falling of a single lunch box.

[0061] Furthermore, in order to balance the force on the lunch boxes, a second falling assembly 204 is also included. The second falling assembly 204 is arranged on the front and rear sides of the accommodating cavity to control the lifting state of the edge of the lower lunch box in the stacked lunch boxes.

[0062] Cooperating with the second falling components 204 on the front and rear sides, the adaptability to lunch boxes of different specifications is further improved. The overall structure is simple and reliable, and effectively solves the double-drop or jamming problem that is prone to occur in traditional box dropping devices.

[0063] The combined design of the second falling component 204 and the first falling component 203 ensures that the lunch box falls in a balanced manner through four-way coordinated lifting, which is particularly suitable for larger (or heavier) lunch boxes.

[0064] The second falling component 204 and the first falling component 203 are located at the same horizontal height, so that the second falling component 204 and the first falling component 203 can simultaneously lift the four sides of the edge of a lunch box.

[0065] The second drop assembly 204 includes a cylinder and a second drop plate 2041 ; the cylinder is fixedly disposed in the frame 201 , and the second drop plate 2041 is disposed on the output end of the cylinder and is clamped under the edge of the lunch box through its upper side.

[0066] A third arc-shaped edge 20411 is provided on the upper side of the second drop plate 2041 for snapping onto the edge of the lunch box to lift the lunch box.

[0067] When the cylinder is extended, the third curved edge 20411 on the lower side of the second drop plate 2041 is clamped under the edge of the lunch box to lift the lunch box.

[0068] When the cylinder is reset, the third arc-shaped edge 20411 of the second drop plate 2041 retreats and leaves below the edge of the lunch box, thereby canceling the support for the lunch box, and the lunch box falls downward under the action of gravity.

[0069] Of course, in order to ensure the precise drop of a single lunch box, the first drop component 203 and the second drop component 204 are controlled synchronously.

[0070] The working process of the lunch box dropping mechanism 2 is as follows:

[0071] 1. In the initial state, the cylinders of the lifting assembly 202, the first falling assembly 203, and the second falling assembly 204 are all in the extended state:

[0072] The first lifting plate 2021 of the lifting assembly 202 is clamped under the edge of the upper lunch box through the first curved edge 20211 to support all the upper lunch boxes.

[0073] The first drop plate 2031 of the first drop assembly 203 and the second drop plate 401 of the second drop assembly 204 are clamped around the bottom edge of the lunch box through the second curved edge 20311 and the third curved edge 20411.

[0074] 2. When you need to release a single lunch box:

[0075] a) The cylinder of the first drop assembly 203 is reset first, driving the first drop plate 2031 to retract, so that the second curved edge 20311 is separated from the edge of the bottom lunch box; the second drop assemblies 204 on the front and rear sides move synchronously with the first drop assembly 203;

[0076] b) The bottom lunch box falls freely under the action of gravity, and the lifting component 202 remains in the lifting state to ensure that the upper lunch box does not fall with it.

[0077] 3. After completing a single box drop:

[0078] a) The cylinder of the first drop assembly 203 extends again, causing the first drop plate 2031 to move below the edge of the penultimate layer of lunch boxes (the bottom layer of the original upper layer); the second drop assemblies 204 on the front and rear sides move synchronously with the first drop assembly 203;

[0079] b) The cylinder of the lifting assembly 202 is briefly reset and immediately re-extended, adjusting the position of the first lifting plate 2021 to below the edge of the new upper lunch box.

[0080] 4. Repeat the above process to achieve continuous and stable single box falling, releasing only the bottom lunch box in the stack each time.

[0081] The lunch box is dropped onto the conveying mechanism 1 by the lunch box dropping mechanism 2 to be transferred to the rice forming mechanism 3 .

[0082] The rice forming mechanism 3 includes a fixing frame 301, a pressing assembly 302, and a mold assembly 303;

[0083] The fixing frame 301 is used to support the pressing assembly 302 and the mold assembly 303;

[0084] The pressing assembly 302 is located on the upper side of the mold assembly 303 and is used to extrude the rice in the mold assembly 303;

[0085] The mold assembly 303 is used to guide the poured rice into the lunch box below it.

[0086] The pressing assembly 302 includes a pushing cylinder 3021 and a pressing block 3022 . The pushing cylinder 3021 is disposed on the top of the fixing frame 301 , and an output end thereof is connected to the pressing block 3022 . The pressing block 3022 is disposed facing the mold assembly 303 .

[0087] The rice forming mechanism 3 can realize efficient and automatic forming of rice through the coordinated cooperation of the fixed frame 301, the pressing component 302 and the mold component 303. The pressing component 302 is located above the mold component 303, and the rice is accurately squeezed by the cylinder-driven pressing block, and cooperates with the liftable forming rice hopper in the mold component 303 to ensure that the rice can be quickly formed and accurately introduced into the lunch box. The structural design is reasonable and the operation is simple. It not only improves the efficiency and quality of rice forming, but also can adapt to the needs of lunch boxes of different shapes, and has significant practicality and promotion value.

[0088] The mold assembly 303 includes a forming rice hopper 3031 and a lifting assembly 3032. The lifting assembly 3032 is set on the fixed frame 301 and is used to drive the forming rice hopper 3031 to move up and down in the vertical direction. The rice contained in the forming rice hopper 3031 is squeezed by the pressing assembly 302 and formed in the lunch box.

[0089] The rice is quantitatively poured into the rice forming hopper 3031 by other equipment or manually.

[0090] A forming portion 30311 is provided on the lower side of the forming rice hopper 3031 , and the size and shape of the forming portion 30311 match the area for placing rice in the lunch box.

[0091] The pressing block 3022 of the pressing assembly 302 matches the size and shape of the forming portion 30311 .

[0092] For example, according to the meal preparation situation, the lunch box needs to hold half of the rice, so the forming portion 30311 is the same size as half of the lunch box and is located above the half.

[0093] The shape of the forming portion 30311 can be designed to be round, square, heart-shaped or other customized shapes according to actual needs to meet the aesthetic and functional requirements of different dining scenes, and can further improve the efficiency, quality and adaptability of rice forming.

[0094] The lifting assembly 3032 includes a fixed plate 30321, a drive motor 30322, a movable plate 30323, and a sliding rod 30324; the sliding rod 30324 is provided with a plurality of them in the vertical direction, the fixed plate 30321 is sleeved on the sliding rod 30324 and fixed; the movable plate 30323 is slidably sleeved on the sliding rod 30324, the drive motor 30322 is fixed on the movable plate 30323, and the output end is connected to the side of the fixed plate 30321; one side of the movable plate 30323 is connected to the forming rice bucket 3031.

[0095] The mold assembly 303 further includes a clamping member 3033 , which is disposed on the movable plate 30323 and fixedly connected to the rice forming hopper 3031 .

[0096] The clamping piece 3033 can be used to easily replace the formed rice bucket 3031 with different sizes and shapes.

[0097] The working process of the rice forming mechanism 3 is as follows:

[0098] 1. Initial preparation stage

[0099] Place the lunch box in a fixed position below the mold assembly 303, ensuring that it is aligned with the forming portion 30311 of the forming rice hopper 3031.

[0100] Pour the cooked rice into the forming rice hopper 3031 , and the rice will naturally fill the cavity of the forming part 30311 .

[0101] 2. Pressing and forming stage

[0102] The pushing cylinder 3021 of the pressing assembly 302 is started, driving the pressing block 3022 to move downward, applying pressure to the rice in the forming rice hopper 3031.

[0103] The shape of the pressing block 3022 matches the forming portion 30311 to ensure that the rice is evenly squeezed to form a shape consistent with the inner cavity of the lunch box.

[0104] 3. Lifting and demoulding stage

[0105] After the pressing is completed, the driving motor 30322 of the lifting assembly 3032 is started, driving the movable plate 30323 to move upward along the sliding rod 30324, so that the forming rice bucket 3031 is lifted.

[0106] As the forming rice hopper 3031 rises, the pressing block 3022 remains stationary, so that the forming portion 30311 is separated from the lunch box and demoulded, and falls completely into the lunch box.

[0107] 4. Reset phase

[0108] Push the cylinder 3021 to start, driving the pressing block 3022 to move upward and reset;

[0109] The lifting assembly 3032 drives the rice forming hopper 3031 to rise to the initial position, preparing for the next rice filling and pressing.

[0110] Waiting for the next round of operations.

[0111] The rice is pressed into the lunch box by the rice forming mechanism 3 and then transferred to the subsequent process equipment through the conveying mechanism 1 for further processing.

[0112] Correction components are provided on both sides of the conveying mechanism 1 to ensure that the lunch box is conveyed in a standard posture on the conveying mechanism 1.

[0113] The conveying mechanism 1 is also provided with a number of lunch box jigs 101 at intervals. The width of each lunch box jig 101 matches the width of the lunch box. The lunch box is accurately dropped into each lunch box jig 101 by the lunch box dropping mechanism 2 so that subsequent pressing is more accurate.

[0114] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
