Description

Technical Field

[0001] This invention belongs to the field of food machinery technology, and specifically relates to a rice dispensing machine. Background Technology

[0002] When we get our food in a cafeteria or restaurant, the rice is manually scooped into containers. This manual method makes it difficult to accurately control the amount of rice served. Furthermore, the rice is not always properly compacted, affecting its shape within the container. Traditional manual rice serving is inefficient.

[0003] Patent application CN201210342871.2 discloses an automatic rice serving machine, including a frame. From top to bottom, the frame includes a squeezing mechanism, a rice hopper, at least three sets of quantitative rice dispensing devices, a rice outlet trough, a plate positioning device, and a rice serving machine control system. The squeezing mechanism includes a motor, a screw, and a pressure block. One end of the screw is connected to the motor, and the other end is connected to the pressure block. Each set of quantitative rice dispensing devices includes a quantitative rice trough, a blade, a pusher, and a cylinder. The piston rod of the cylinder is connected to the pusher, which slides at one end of the quantitative rice trough. The blade is placed above the quantitative rice trough and flush with the opening above it, with one end fixed to the pusher. The plate positioning device includes cylinders placed around a platform, with a push plate installed at the end of the piston rod of each cylinder. By employing the squeezing mechanism, quantitative rice dispensing devices, and plate positioning device, and connecting to the rice serving machine control system, an unattended self-service system is achieved, improving rice serving efficiency and ensuring the accuracy of each serving's portion size.

[0004] The rotational motion of the motor is converted into the downward movement of the pressing block. Under the pressure of the pressing block, the rice is forced through the outlet of the rice hopper into the quantitative rice trough. The amount of rice in the quantitative rice trough is the amount required by the diner. Then, the piston rod of the cylinder pushes the pusher to push the rice out of the quantitative rice trough and into the rice outlet trough. Finally, the rice falls into the plate from the outlet of the rice outlet trough.

[0005] The aforementioned device cannot shape the rice, which causes the rice to spill easily during the falling process and affects the appearance. Summary of the Invention

[0006] In order to solve the above-mentioned problems in the existing technology, the purpose of the present invention is to provide a rice dispensing machine that can dispense rice in a quantitative manner and shape the rice.

[0007] The technical solution adopted in this invention is as follows: A meal dispensing machine includes a housing, a meal storage box at the top of the housing, a dispersing mechanism corresponding to the meal storage box inside the housing, a quantitative shaping device and an opening and closing drive mechanism for driving the quantitative shaping device to open and close inside the housing; the quantitative shaping device includes a frame fixed inside the housing, a quantitative unit and a shaping unit located below the quantitative unit inside the frame, and the output end of the opening and closing drive mechanism drives the quantitative unit and the shaping unit to open and close respectively.

[0008] In this invention, after the rice in the storage box falls into the dispersing mechanism, the dispersing mechanism disperses the rice. The opening and closing drive mechanism drives the metering unit to open, allowing the dispersed rice to fall into the metering unit. The opening and closing drive mechanism then closes the metering unit, thus separating a fixed amount of rice within the metering unit. The opening and closing drive mechanism then opens the shaping unit, allowing the fixed amount of rice to fall into the shaping unit. The opening and closing drive mechanism then closes the shaping unit, allowing the inner cavity of the shaping unit to compress the rice into a specific rice ball shape. Finally, after the opening and closing drive mechanism opens the shaping unit, the shaped rice falls directly into the container. The specific shaped rice balls do not spill during the falling process, ensuring the aesthetic appearance of the rice contained in the container.

[0009] In a preferred embodiment of the present invention, the rice storage box includes a box body, inside which is a rice storage hopper that is wider at the top and narrower at the bottom. A pull-out bottom plate for sealing the bottom of the rice storage hopper is inserted into the lower part of the box body, and a cover plate is provided on the top of the box body. A heating unit is installed in the space between the box body and the rice storage hopper. The box body can be removed from the shell and is used to hold rice. When rice is not needed, the box body serves as a container for storing rice, and the heating unit inside the box can keep the rice warm. When rice needs to be served, the box body filled with rice is installed on the top of the shell, the pull-out bottom plate is pulled out, and the rice falls into the dispersing mechanism.

[0010] In a preferred embodiment of the present invention, a positioning pin hole is provided at the bottom of the box body, and a positioning pin is provided at the top of the shell body, with the positioning pin engaging with the positioning pin hole. When the food storage box is placed on top of the shell body, the positioning pin at the top of the shell body inserts into the positioning pin hole at the bottom of the box body, ensuring accurate installation of the food storage box.

[0011] In a preferred embodiment of the present invention, the dispersing mechanism includes a dispersing chamber fixed within the housing, corresponding to the rice storage box. A plurality of dispersing shafts are rotatably connected within the dispersing chamber, each shaft having a plurality of dispersing teeth. A transmission gear is fixed to each dispersing shaft, with the transmission gears on adjacent dispersing shafts meshing. A dispersing drive mechanism is installed within the housing, and its output end is connected to a drive gear, which meshes with one of the transmission gears. The dispersing drive mechanism drives the drive gear to rotate, which in turn drives the plurality of transmission gears to rotate. This causes the dispersing shafts to rotate within the dispersing chamber, and the dispersing teeth on the shafts evenly disperse the rice, preventing it from clumping and ensuring that the rice falls smoothly into the metering unit.

[0012] In a preferred embodiment of the present invention, the metering unit includes an upper metering guide plate and a lower metering guide plate fixed to the frame, with a metering cylinder connected between the upper and lower metering guide plates. A rice receiving hopper is fixed to the upper side of the upper metering guide plate. An upper metering opening / closing plate for opening and closing the upper opening of the metering cylinder is fitted inside the upper metering guide plate, and a lower metering opening / closing plate for opening and closing the lower opening of the metering cylinder is fitted inside the lower metering guide plate. The output end of the opening / closing drive mechanism is connected to the upper and lower metering opening / closing plates respectively. When the upper metering opening / closing plate is open, the lower metering opening / closing plate is closed, allowing rice to fall smoothly into the metering cylinder. After the metering cylinder is full of rice, the upper metering opening / closing plate closes, and the lower metering opening / closing plate and the shaping unit open, allowing rice to fall smoothly into the shaping unit.

[0013] As a preferred embodiment of the present invention, the shaping unit includes a shaping lower guide plate fixed on the frame; a shaping upper connecting plate is also sleeved inside the shaping lower guide plate, and a shaping lower connecting plate is sleeved inside the shaping lower guide plate. The output end of the opening and closing drive mechanism is connected to the shaping upper connecting plate and the shaping lower connecting plate respectively. A shaping upper opening and closing mold is connected to the shaping upper connecting plate, and a shaping lower opening and closing mold is connected to the shaping lower connecting plate. The shaping upper opening and closing mold and the shaping lower opening and closing mold form a rice ball shape.

[0014] Both the lower metering plate and the upper shaping plate are fitted inside the lower metering guide plate, and they can open and close synchronously. When the lower metering plate and the upper shaping plate are open, the lower shaping mold is closed, and the rice in the metering cylinder falls into the lower shaping mold. After the upper shaping mold is closed, the rice is compressed into a specific rice ball shape. Finally, the lower shaping mold is opened, and the rice falls into the container below.

[0015] As a preferred embodiment of the present invention, the opening and closing drive mechanism includes an opening and closing drive unit installed in the housing. The output end of the opening and closing drive unit is connected to a transmission unit. The output end of the transmission unit is connected to three shift forks connected in sequence. Actuating shafts are connected between the quantitative upper opening and closing plate, the quantitative lower opening and closing plate and the shaping upper connecting plate, and the shaping lower connecting plate. The three shift forks and the three actuating shafts are matched one-to-one.

[0016] The opening and closing drive unit drives the transmission unit, which in turn drives three shift forks to rotate. As the shift forks rotate, they push and pull the actuating shaft, thereby driving the upper and lower quantitative opening and closing plates, the upper and lower shaping connecting plates. Using shift forks as the drive mechanism reduces the space occupied by the opening and closing mechanism, which is beneficial for miniaturizing the meal dispensing machine.

[0017] As a preferred embodiment of the present invention, the transmission unit includes a drive shaft connected to the output end of the opening and closing drive unit, a fixed shaft connected inside the housing, three drive arms rotatably connected to the fixed shaft, a rolling wheel rotatably connected to the other end of the drive arm, three cam disks fixed on the drive shaft, cam grooves provided in the cam disks, the rolling wheel being provided in the cam grooves, and the three drive arms and three shift forks being fixed in a one-to-one correspondence.

[0018] The opening and closing drive unit drives the drive shaft to rotate, and the cam disk on the drive shaft rotates accordingly. As the rolling wheel on the drive arm rolls along the cam groove on the cam disk, the rotation of the cam disk will drive the drive arm to swing back and forth at specific time points. When the drive arm swings back and forth, it drives the shift fork to swing back and forth, so that the shift fork can drive the shift shaft to move, thereby realizing the driving of the quantitative upper opening and closing plate, the quantitative lower opening and closing plate, the shaping upper connecting plate, and the shaping lower connecting plate.

[0019] As a preferred embodiment of the present invention, there are two quantitative upper opening and closing plates, two quantitative lower opening and closing plates, two shaping upper connecting plates, and two shaping lower connecting plates. Both sides of the frame are provided with a shift fork, a drive shaft, and a fixed shaft. The drive shaft is rotatably connected to the housing. Synchronous gears are fixed on both drive shafts, and the synchronous gears on the two drive shafts mesh.

[0020] The two drive shafts are driven by synchronous gears, which in turn drive the shift forks on both sides of the frame to move synchronously. The quantitative upper opening and closing plate, quantitative lower opening and closing plate, shaping upper connecting plate, and shaping lower connecting plate on both sides all move synchronously to ensure reliable opening and closing.

[0021] As a preferred embodiment of the present invention, the bottom of the housing is provided with a support plate for placing a rice bowl, and the front side of the housing is provided with an opening and closing door.

[0022] The beneficial effects of this invention are as follows: In this invention, after the rice in the storage box falls into the dispersing mechanism, the dispersing mechanism disperses the rice. The opening and closing drive mechanism drives the metering unit to open, allowing the dispersed rice to fall into the metering unit. The opening and closing drive mechanism then closes the metering unit, thus separating a fixed amount of rice within the metering unit. The opening and closing drive mechanism then opens the shaping unit, allowing the fixed amount of rice to fall into the shaping unit. The opening and closing drive mechanism then closes the shaping unit, allowing the inner cavity of the shaping unit to compress the rice into a specific rice ball shape. Finally, after the opening and closing drive mechanism opens the shaping unit, the shaped rice falls directly into the container. The specific shaped rice balls do not spill during the falling process, ensuring the aesthetic appearance of the rice contained in the container. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the invention can be combined with each other.

[0027] like Figures 1-12 As shown, the rice dispenser of this embodiment includes a housing 1, a rice storage box 2 is provided on the top of the housing 1, a dispersing mechanism 3 corresponding to the rice storage box 2 is provided inside the housing 1, a quantitative shaping device 4 and an opening and closing drive mechanism 5 for driving the quantitative shaping device 4 to open and close are installed inside the housing 1; the quantitative shaping device 4 includes a frame 41 fixed inside the housing 1, a quantitative unit 42 and a shaping unit 43 located below the quantitative unit 42 are provided inside the frame 41, and the output end of the opening and closing drive mechanism 5 drives the quantitative unit 42 and the shaping unit 43 to open and close respectively; a support plate 12 for placing rice bowls is provided at the bottom of the housing 1, and an opening and closing door 13 is provided on the front side of the housing 1.

[0028] After the rice in the storage box of this invention falls into the dispersing mechanism 3, the dispersing mechanism 3 disperses the rice. The opening and closing drive mechanism 5 drives the metering unit 42 to open, and the dispersed rice falls into the metering unit 42. The opening and closing drive mechanism 5 then closes the metering unit 42, thus separating a fixed amount of rice within the metering unit 42. The opening and closing drive mechanism 5 opens the shaping unit 43, and the fixed amount of rice falls into the shaping unit 43. The opening and closing drive mechanism 5 then closes the shaping unit 43, and the inner cavity of the shaping unit 43 can compress the rice into a specific rice ball shape. Finally, after the opening and closing drive mechanism 5 opens the shaping unit 43, the shaped rice falls directly into the container. The specific shaped rice balls will not spill during the falling process, and the aesthetic appearance of the rice in the container is ensured.

[0029] Specifically, the rice storage box 2 includes a box body 21, inside which is a rice storage hopper 22 that is wider at the top and narrower at the bottom. A pull-out bottom plate 23 for sealing the bottom of the rice storage hopper 22 is inserted into the lower part of the box body 21. A cover plate 24 is provided on the top of the box body 21. A heating unit is installed in the space between the box body 21 and the rice storage hopper 22. The box body 21 can be removed from the shell 1 and is used to hold rice. When rice is not needed, the box body 21 serves as a container for storing rice, and the heating unit inside the box body 21 can keep the rice warm. When rice needs to be served, the box body 21 filled with rice is installed on the top of the shell 1, the pull-out bottom plate 23 is pulled out, and the rice falls into the dispersing mechanism 3.

[0030] The bottom of the box body 21 is provided with a positioning pin 11 hole, and the top of the shell 1 is provided with a positioning pin 11, which cooperates with the positioning pin 11 hole. When the food storage box 2 is placed on top of the shell 1, the positioning pin 11 on the top of the shell 1 is inserted into the positioning pin 11 hole on the bottom of the box body 21 to ensure accurate installation of the food storage box 2.

[0031] Specifically, the dispersing mechanism 3 includes a dispersing chamber 31 fixed inside the housing 1, which corresponds to the rice storage box 2. Several dispersing shafts 32 are rotatably connected inside the dispersing chamber 31. Several dispersing teeth are provided on each dispersing shaft 32, and transmission gears 33 are fixed on each dispersing shaft 32. The transmission gears 33 on adjacent dispersing shafts 32 mesh with each other. A dispersing drive mechanism 34 is installed inside the housing 1. The output end of the dispersing drive mechanism 34 is connected to a drive gear, which meshes with one of the transmission gears 33. The dispersing drive mechanism 34 drives the drive gear to rotate, which in turn drives the several transmission gears 33 to rotate. This causes the several dispersing shafts 32 to rotate within the dispersing chamber 31. The dispersing teeth on the dispersing shafts 32 evenly disperse the rice, preventing it from clumping and ensuring that the rice falls smoothly into the metering unit 42.

[0032] Specifically, the metering unit 42 includes an upper metering guide plate 421 and a lower metering guide plate 422 fixed to the frame 41. A metering cylinder 423 is connected between the upper metering guide plate 421 and the lower metering guide plate 422. A rice receiving hopper 424 is fixed to the upper side of the upper metering guide plate 421. An upper metering opening and closing plate 425 for opening and closing the upper opening of the metering cylinder 423 is sleeved inside the upper metering guide plate 421. A lower metering opening and closing plate 426 for opening and closing the lower opening of the metering cylinder 423 is sleeved inside the lower metering guide plate 422. The output end of the opening and closing drive mechanism 5 is connected to the upper metering opening and closing plate 425 and the lower metering opening and closing plate 426 respectively. When the upper metering opening and closing plate 425 is open, the lower metering opening and closing plate 426 is closed, so the rice can fall smoothly into the metering cylinder 423. After the measuring cylinder 423 is filled with rice, the upper measuring plate 425 closes and the lower measuring plate 426 and the shaping unit 43 open, allowing the rice to fall smoothly into the shaping unit 43.

[0033] Specifically, the shaping unit 43 includes a shaping lower guide plate 431 fixed on the frame 41; a shaping upper connecting plate 432 is also sleeved inside the quantitative lower guide plate 422, and a shaping lower connecting plate 433 is sleeved inside the shaping lower guide plate 431. The output end of the opening and closing drive mechanism 5 is connected to the shaping upper connecting plate 432 and the shaping lower connecting plate 433 respectively. A shaping upper opening and closing mold 434 is connected to the shaping upper connecting plate 432, and a shaping lower opening and closing mold 435 is connected to the shaping lower connecting plate 433. The shaping upper opening and closing mold 434 and the shaping lower opening and closing mold 435 form a rice ball shape.

[0034] The lower quantitative opening and closing plate 426 and the upper shaping connecting plate 432 are both fitted inside the lower quantitative guide plate 422, and can open and close synchronously. When the lower quantitative opening and closing plate 426 and the upper shaping connecting plate 432 are open, the lower shaping mold 435 is in the closed state, and the rice in the quantitative cylinder 423 falls into the lower shaping mold 435. After the upper shaping mold 434 is closed, the rice can be squeezed into a specific rice ball shape. Finally, the lower shaping mold 435 is opened, and the rice can fall into the container below.

[0035] Specifically, the opening and closing drive mechanism 5 includes an opening and closing drive unit 51 installed in the housing 1. The output end of the opening and closing drive unit 51 is connected to a transmission unit 52. The output end of the transmission unit 52 is connected to three shift forks 53 connected in sequence. Actuating shafts 54 are connected between the quantitative upper opening and closing plate 425, the quantitative lower opening and closing plate 426 and the shaping upper connecting plate 432, and the shaping lower connecting plate 433. The three shift forks 53 and the three actuating shafts 54 are matched one-to-one.

[0036] The opening and closing drive unit 51 drives the transmission unit 52 to operate. The transmission unit 52 drives the three shift forks 53 to rotate respectively. When the shift forks 53 rotate, they push and pull the actuating shaft 54, thereby driving the upper quantitative opening and closing plate 425, the lower quantitative opening and closing plate 426, the upper shaping connecting plate 432, and the lower shaping connecting plate 433. By using the shift forks 53 to drive the mechanism, the space occupied by the opening and closing drive mechanism 5 can be reduced, which is beneficial to the miniaturization of the meal dispensing machine.

[0037] The transmission unit 52 includes a drive shaft 521 connected to the output end of the opening and closing drive unit 51. A fixed shaft 522 is connected inside the housing 1. Three drive arms 523 are rotatably connected to the fixed shaft 522. A rolling wheel 524 is rotatably connected to the other end of the drive arm 523. Three cam disks 525 are fixed on the drive shaft 521. A cam groove 526 is provided in the cam disk 525. The rolling wheel 524 is provided in the cam groove 526. The three drive arms 523 are fixed in correspondence with the three shift forks 53.

[0038] The opening and closing drive unit 51 drives the drive shaft 521 to rotate, and the cam disk 525 on the drive shaft 521 rotates accordingly. Since the rolling wheel 524 on the drive arm 523 rolls along the cam groove 526 on the cam disk 525, the rotation of the cam disk 525 will drive the drive arm 523 to swing back and forth at specific time points. When the drive arm 523 swings back and forth, it drives the shift fork 53 to swing back and forth, so that the shift fork 53 can drive the shift shaft 54 ​​to move, thereby realizing the driving of the upper quantitative opening and closing plate 425, the lower quantitative opening and closing plate 426, the upper shaping connecting plate 432, and the lower shaping connecting plate 433.

[0039] In this embodiment, there are two quantitative upper opening and closing plate 425, two quantitative lower opening and closing plate 426, two shaping upper connecting plate 432, and two shaping lower connecting plate 433. Both sides of the frame 41 are provided with a fork 53, a drive shaft 521, and a fixed shaft 522. The drive shaft 521 is rotatably connected to the housing 1. Synchronous gears 527 are fixed on both drive shafts 521, and the synchronous gears 527 on the two drive shafts 521 mesh.

[0040] Two drive shafts 521 are driven by synchronous gears 527, which drive the shift forks 53 on both sides of the frame 41 to move synchronously. The quantitative upper opening and closing plate 425, quantitative lower opening and closing plate 426, shaping upper connecting plate 432, and shaping lower connecting plate 433 on both sides all move synchronously to ensure reliable opening and closing.

[0041] It should be noted that: The cam grooves 526 on the bottom and top cam discs 525 have identical shapes and positions, thus ensuring that the actions of the quantitative upper opening and closing plate 425 and the shaping lower opening and closing mold 435 are completely synchronized. The quantitative lower opening and closing plate 426 and the shaping upper connecting plate 432 are connected by a toggle shaft 54, which is driven by a toggle fork 53, ensuring that the actions of the quantitative lower opening and closing plate 426 and the shaping upper opening and closing mold 434 are completely synchronized.

[0042] Based on the timing requirements of the quantitative upper opening and closing plate 425, the quantitative lower opening and closing plate 426, the shaping upper opening and closing mold 434, and the shaping lower opening and closing mold 435, the shape of the cam groove 526 on each layer of cam disk 525 is designed. Ultimately, the quantitative and shaping device 4 cycles through four states: State 1, quantitative upper opening and closing plate 425 is open, quantitative lower opening and closing plate 426 and shaping upper opening and closing mold 434 are closed, and shaping lower opening and closing mold 435 is open; State 2, quantitative upper opening and closing plate 425, quantitative lower opening and closing plate 426, shaping upper opening and closing mold 434, and shaping lower opening and closing mold 435 are all closed; State 3, quantitative upper opening and closing plate 425 is closed, quantitative lower opening and closing plate 426 and shaping upper opening and closing mold 434 are open, and shaping lower opening and closing mold 435 is closed; State 4, quantitative upper opening and closing plate 425, quantitative lower opening and closing plate 426, shaping upper opening and closing mold 434, and shaping lower opening and closing mold 435 are all closed. This allows the quantitative and shaping processes to be performed continuously.
