[0047] Figure 1 The automatic rice serving unit of the meal continuous serving vending machine of the present application is shown, which comprises a rack 1, a rice storage device 2 arranged on the rack 1, a rice distribution device 3 arranged below the rice storage device 2, a conveying belt 4 arranged below the rice distribution device 2 for conveying rice, and further comprising:

[0048] A rice shaping device 5 arranged at the end of the conveying belt 4;

[0049] Steam components 6 arranged on both sides of the rice distribution device 3 to keep the rice in the rice distribution device 3 at a constant temperature, the steam components 6 being in communication with a constant temperature heating water tank 61, and the rice shaping device 5 and the rice distribution device 3 cooperating with each other in space;

[0050] The rice shaping device 5 comprises a rice cup assembly 51 arranged below the end of the rice distribution device 3 and having a space for accommodating rice, a rice scraping plate assembly 52 arranged above the end of the rice distribution device 3, and a rice shaping assembly 53 arranged above the rice cup assembly 51 and having its lower end extending into the rice cup assembly 51 to shape the rice.

[0051] Working principle: The automatic rice serving unit of the meal vending machine provided by the present application is provided with an operation screen, and the required amount of rice is set on the operation screen. The system mainly comprises a rack 1, a rice storage device 2, a rice distribution device 3, and a rice shaping device 5.

[0052] The rice storage device 2 is arranged on the rack 1 and is used to store the rice to be distributed. The rice distribution device 3 is located below the rice storage device 2, and a certain amount of rice falls from the rice outlet at the bottom of the rice storage device 2 into the space between the rice distribution device 3. The rice in the rice distribution device 3 is conveyed to the rice shaping device 5 through the conveying belt 4.

[0053] The rice distributing device 3 conveys loose rice into the rice shaping device 5. The shaping device is composed of a rice cup assembly 51, a cutting and scraping plate assembly 52, and a rice shaping assembly 53. The rice cup assembly 51 is located at the end of the rice distributing device 3, providing a space to hold the rice. The cutting and scraping plate assembly 52 is located above the rice distributing device 3, used to cut and scrape the loose rice into the rice cup assembly 51. The rice shaping assembly 53 is located above the rice cup assembly 51, with its lower end extending into the rice cup assembly 51, to perform the final shaping of the rice, ensuring the rice is shaped neatly and aesthetically. The cutting amount of the rice is determined by the distance the conveying belt 4 carries the rice, and the distance the conveying belt 4 carries the rice can be adjusted according to the set rice amount.

[0054] In addition, the system is also equipped with steam components 6 installed on both sides of the rice distributing device 3. These steam components 6 can continuously inject steam into the cavity of the rice distributing device 3, keeping the rice at a constant temperature during distribution and conveying, ensuring the taste and freshness of the rice.

[0055] The entire system achieves automatic distribution, conveying, and shaping of rice through the coordinated work of each component, greatly improving the automation level and work efficiency of the vending machine. At the same time, the constant temperature control function also ensures the taste and freshness of the rice, improving the dining experience of the users.

[0056] In the above scheme, the rice dividing device 3 comprises: a pair of rice clamping plates 31 arranged below the rice storage device 2, two rice blocking plates 39 arranged at the front ends of the rice clamping plates 31 respectively, a rice receiving plate component slidingly arranged through a side wall of one of the rice clamping plates 31, and the conveying belt 4 located below the rice clamping plates 31; the rice clamping plates 31, the rice blocking plates 39 and the conveying belt 4 form a cavity for conveying rice in space; the rice receiving plate component comprises a U-shaped rice receiving plate 34 for shaping and limiting the amount of falling rice in space, one end of the U-shaped rice receiving plate 34 penetrating through the side wall of one of the rice clamping plates 31 and abutting against the other rice clamping plate 31, and the other end connected with the output shaft of the air cylinder; wherein a certain gap is reserved between the rice receiving plate and the conveying belt 4 in terms of spatial height position. By using this technical method, first, the air cylinder drives the front end of the U-shaped rice receiving plate 34 to slide to a predetermined position on one side of the rice clamping plate 31. At this time, the rice in the rice storage device 2 begins to fall. As the rice falls, they enter the cavity formed by the rice clamping plates 31, the rice blocking plates 39 and the conveying belt 4. In this process, the rice blocking plates 39 prevent the rice from falling off the front end of the rice clamping plates 31, and when the space inside the U-shaped rice receiving plate 34 is filled with rice, the air cylinder starts to drive the U-shaped rice receiving plate 34 to slide to one side. Since the shape and size of the U-shaped rice receiving plate 34 are fixed, the rice falls from the U-shaped rice receiving plate 34 to the conveying belt 4, and the conveying belt 4 starts to convey the rice to the next process for further processing at a predetermined speed and direction. The rice receiving plate and the conveying belt 4 have a certain gap, and when the rice falls into the rice receiving plate, the output shaft 35 of the air cylinder drives the U-shaped rice receiving plate 34 to move backward, and the rice falls from the rice receiving plate to the conveying belt 4, which avoids the problem that there is no gap between the rice and the rice conveying component, causing the subsequent rice to fail to fall. Such design can improve the efficiency and quantitative distribution of rice conveying. According to the demand of personnel for rice, the movement distance of the conveying belt 4 can be adjusted to control the weight of the rice conveyed to the next process. The air cylinder continuously drives the U-shaped rice receiving plate 34 to reciprocate, thereby realizing continuous and quantitative distribution of rice.

[0057] In the above scheme, each sandwich plate 31 is a double-layer structure, and the inner space has a region for accommodating steam. Each sandwich plate 31 has a plurality of through holes I 32 on one side that are in communication with the cavity, and a plurality of through holes II 33 on the other side that are in communication with the steam component 6 outlet. The two sandwich plates 31 are connected by a connecting component, which includes: a pair of ball screws 36 arranged at the front and rear ends of the sandwich plate 31. The front and rear ends of each sandwich plate 31 are connected to the slide block seat 37 on the ball screw 36 through a connecting piece. The two ball screws 36 are drivingly connected by a synchronous belt 38. The slide block seats 37 on the ball screws 36 are oppositely arranged, and one of the ball screws 36 is drivingly connected to the output shaft of the output motor. With this technical method, when the rice enters the cavity, the steam component 6 starts to work, and it will generate steam from the constant-temperature heating tank 61 and enter the inner space of the sandwich plate 31 through the through holes II 33. These steams accumulate in the inner space of the sandwich plate 31 and flow into the cavity formed by the sandwich plate 31, the blocking plate 39, and the conveying belt 4 through the through holes I 32. Since the sandwich plate 31 is a double-layer structure, the flow and diffusion of the steam in the inner space can be effectively controlled, thereby achieving uniform heating of the rice. The two ball screws 36 are arranged at the front and rear ends of the sandwich plate 31 and oppositely arranged in pairs. As a high-precision transmission device, the ball screw 36 has excellent straightness and wear resistance, and can provide stable and precise movement control.

[0058] The front and rear ends of the sandwich plate 31 are connected to the slide block seat 37 on the ball screw 36 through a connecting piece. This means that when the ball screw 36 rotates, the slide block seat 37 will move linearly along the ball screw 36, thereby driving the sandwich plate 31 to move accordingly. This connection mode not only ensures the stable movement of the sandwich plate 31, but also realizes precise position control.

[0059] The two ball screws 36 are drivingly connected by a synchronous belt 38. The synchronous belt 38 has the advantages of stable transmission, low noise, and high transmission efficiency, and can ensure that the two ball screws 36 rotate synchronously, thereby ensuring that the movement of the sandwich plate 31 at the front and rear ends remains consistent.

[0060] One of the ball screws 36 is drivingly connected to the output shaft of the output motor. The output motor provides power for the ball screw 36, and drives the rotation of the ball screw 36 to realize the movement of the sandwich plate 31. Since the ball screw 36 has high transmission precision, the movement of the sandwich plate 31 will also be very precise and stable.

[0061] In operation, when the output motor is started, it drives the ball screw 36 connected thereto to rotate. Through the transmission of the synchronous belt 38, the other ball screw 36 also rotates synchronously. With the rotation of the ball screw 36, the slider seat 37 moves linearly along the ball screw 36, thereby driving the rice plate 31 to move correspondingly. The moving direction and speed of the rice plate 31 can be realized by controlling the rotating direction and speed of the output motor.

[0062] In the above scheme, the steam component 6 comprises a plurality of steam nozzles 62 arranged on the frame 1;

[0063] Wherein, the constant temperature heating water tank 61 and each steam nozzle 62 are communicated through a hard connecting pipe 63, the size of each steam nozzle 62 is smaller than the size of the through hole II 33, and the steam nozzle 62 extends into the internal region of the rice plate 31, and a certain gap is reserved in the spatial position. With this technical method, the constant temperature heating water tank 61 is used to store heated water. When the water in the constant temperature heating water tank 61 is heated to a high temperature, steam is generated. According to different needs, the temperature of the water in the constant temperature heating water tank 61 can be adjusted to control the amount of steam generated, and these steam flows to the steam nozzle 62 through the hard connecting pipe 63. The hard connecting pipe 63 ensures the smooth flow of steam from the constant temperature heating water tank 61 to the steam nozzle 62, reduces the loss of steam in the transmission process, and improves the energy utilization efficiency.

[0064] The steam nozzle 62 is arranged on the frame 1, and its size is smaller than the size of the through hole II 33, so that the steam nozzle 62 can pass through the through hole II 33 and extend into the internal space of the rice plate 31. A certain gap is reserved between the steam nozzle 62 and the through hole II 33 to ensure that the steam nozzle 62 and the rice plate 31 do not interfere with each other in space position when the rice plate 31 moves left and right, and also to ensure that the steam can be uniformly sprayed from the nozzle to cover the internal space of the rice plate 31.

[0065] When the steam is sprayed from the steam nozzle 62, it enters the internal space of the rice plate 31 through the through hole II 33 to heat and moisturize the rice. Due to the double-layer structure of the rice plate 31 and the through hole design, the steam can be uniformly distributed around the rice, ensuring that the rice always maintains a hot and moist state during the sale process.

[0066] In this way, the steam component 6 provides continuous heating and moisturizing effect for the rice, improves the taste and flavor of the rice, and also ensures that the rice can maintain an appropriate temperature for a long time.

[0067] In the above scheme, the rice shaping assembly 53 includes a transmission component 531 arranged above the ends of the pair of rice clamping plates 31, a connecting rod 532 with a hollow structure extending into the interior of the rice cup assembly 51, a transmission shaft 534 arranged inside the connecting rod 532 and connected to the motor shaft inside the transmission component 531, a shaping cover 533 arranged at the bottom of the connecting rod 532 for rice shaping, and the transmission component 531 is in transmission connection with the upper end of the connecting rod 532 to make the connecting rod 532 move up and down in space. The lower end of the transmission shaft 534 inside the transmission component 531 is connected to the arc-shaped scraper 535 below the shaping cover 533, and the arc-shaped scraper 535 is rotated left and right by the transmission shaft 534. With this technical method, the transmission component 531 drives the connecting rod 532 to move up and down in space by the motor. The connecting rod 532 has a hollow structure, with a transmission shaft 534 arranged inside and connected to the clicking shaft, and a shaping cover 533 arranged at the bottom. When the transmission component 531 drives the connecting rod 532 to move down, the shaping cover 533 will extend into the interior of the rice cup assembly 51. First, the loose rice is pressed into a semicircle by the extrusion of the shaping cover 533, and then the arc-shaped scraper 535 is rotated by the transmission shaft 534. The main function of the arc-shaped scraper 535 is to make the surface of the rice in the rice cup assembly 51 more flat by rotating. When the transmission component 531 drives the connecting rod 532 to descend and the arc-shaped scraper 535 contacts the rice, the transmission shaft 534 starts to work and drives the arc-shaped scraper 535 to rotate in the interior of the rice cup assembly 51. The rotating action of the arc-shaped scraper 535 will drive the movement and redistribution of the rice. The rotation of the arc-shaped scraper 535 can also break the clumps and uneven parts in the rice, making it more loose and uniform. This uniformly distributed rice is easier to be compacted and shaped by the shaping cover 533, resulting in a more beautiful and compact rice shape. The upper surface of the rice is scraped to be flat, and finally the shaping cover 533 completes the final pressing. After the shaping is completed, the transmission component 531 drives the connecting rod 532 to move up again, and the shaping cover 533 is withdrawn from the rice cup assembly 51. Through appropriate pressure and shape adjustment, the rice shaping assembly 53 compacts and flattens the rice, making it present a beautiful and attractive appearance. This step not only improves the appearance of the dish, but also ensures the compactness and taste of the rice.

[0068] In the above scheme, the rice cup assembly 51 includes: a rice cup 511 arranged above the rice receiving plate, a cylinder component I 502 connected to one side above the rice cup 511 to move the rice cup 511 up and down in space; wherein the width between the pair of rice clamping plates 31 is greater than the width of the rice cup 511. By using this technical method, first of all, the cylinder component I 502 in the rice cup assembly 51 plays a key role. The cylinder component I 502 is connected to one side above the rice cup 511, which can control the rice cup 511 to move up and down in space. This design makes the rice cup 511 can be lifted according to the needs, in order to work with the pair of rice clamping plates 31 and the cutting and scraping plate assembly 52.

[0069] In the above scheme, the cutting and scraping plate assembly 52 includes: a cutting and scraping plate 521 arranged above the rice conveying belt assembly in L shape, a cylinder component II 522 connected to one side of the cutting and scraping plate 521 to move the cutting and scraping plate 521 up and down in space, a connecting block 523 connected to the cylinder component II 522, and a longitudinal driving component to move the cylinder component II 522 longitudinally in space. By using this technical method, first of all, the cylinder component II 522 is started, which drives the lower end of the cutting and scraping plate 521 to be in close contact with the rice conveying device. Then, the longitudinal driving component starts to work, which drives the cutting and scraping plate 521 to move towards the rice cup 511, so that it can scrape the rice into the rice cup 511. After the rice scraping is completed, the cylinder component II 522 drives the cutting and scraping plate 521 to move upwards, and the longitudinal driving component can drive the cylinder component II 522 to move back to the initial position again. The next round of rice scraping operation is carried out.

[0070] In the above scheme, the longitudinal driving component includes: a connecting block 523 connected to the cylinder component II 522, and one side of the connecting block 523 is connected to the output shaft of the longitudinal driving cylinder 524. By using this technical method, first of all, the cylinder component II 522 is connected to one side of the cutting and scraping plate 521, which is responsible for controlling the cutting and scraping plate 521 to move up and down in space. The cutting and scraping plate 521 can be lifted according to the needs, when the pair of rice clamping plates 31 clamps and moves the rice above the rice cup assembly 51, the cylinder component II 522 drives the cutting and scraping plate 521 to move downwards, so that it is in close contact with the pair of rice clamping plates 31.

[0071] Then the longitudinal driving cylinder 524 starts to work. It drives the cylinder component II 522 to move longitudinally in space, which ensures that the cutting and scraping plate 521 can accurately scrape all the rice between the pair of rice clamping plates 31 into the rice cup 511.

[0072] Since the cutting and scraping plate assembly 52 has two degrees of freedom in space, it not only can move up and down under the drive of the cylinder component II 522, but also can move laterally under the control of other driving components. In this way, the cutting and scraping plate 521 can move along the surface of the rice clamping plate 31, and the rice can be uniformly scraped into the rice cup 511.

[0073] When the rice is completely scraped into the rice bowl 511, the cylinder part II 222 works again, driving the cutting and scraping plate 521 to move upward, returning to the initial position, preparing for the next rice scraping operation.

[0074] In the above scheme, the shaping cover 533 is composed of two parts, the upper and lower parts. A plurality of connecting holes 61 are arranged on the two side surfaces of the upper and lower parts of the shaping cover 533. The upper part of the shaping cover 533 has a boss 65 structure. The upper end of the boss 65 is connected with the connecting rod 532 through a quick locking buckle.
