[0031] Wherein, the rice clamping plate I 31 and the rice clamping plate II 32 are internally provided with heating components, the rice clamping plate I 31, the rice clamping plate II 32, the rice blocking plate 51 of the rice blocking plate assembly 5 and the rice feeding plate 41 of the rice feeding plate assembly 4 form a cavity I for accommodating rice, the rice clamping plate II 32 is driven by the driving part I 33 to form a semi-enclosed structure with the L-shaped rice pushing plate 71 of the rice pushing plate assembly 7 for accommodating rice, the L-shaped cutting and scraping plate 61 of the cutting and scraping plate assembly 6 cuts the rice in the cavity I when it vertically descends, and forms a cavity II for extruding and shaping the cut rice when it moves horizontally.

[0032] Working principle:

[0033] Firstly, when the rice serving device starts to work, the blocking plate 51 of the blocking plate assembly 5 on the rack 1 extends between the clamping plate I 31 and the clamping plate II 32, and the front end of the blocking plate 51 abuts against the side wall of the clamping plate II 32. The cavity I for accommodating rice is formed between the blocking plate 51, the clamping plate I 31, the clamping plate II 32, the rice feeding plate 41 and the rice conveying belt 2. The rice in the rice box (not shown in the figure) on the rack 1 falls into the cavity I and forms a preliminary shape. The heating assembly (not shown in the figure) arranged in the clamping plate I 31 and the clamping plate II 32 and the heating plate (not shown in the figure) below the rice conveying belt 2 heat and keep warm the rice in the cavity. At the same time, the blocking plate 51 is retracted inward, the clamping plate II 32 moves forward along the conveying belt by the driving component I 33 arranged thereon, abuts against one side of the L-shaped pushing plate 71 of the pushing plate assembly 7, and forms a semi-enclosed structure. At the same time, the rice in the cavity I moves toward the rice outlet under the action of the rice conveying belt 2. According to the amount of rice clicked by the dining customer through the external screen, the control mechanism on the rack 1 controls the movement distance of the rice conveying belt 2, and then accurately controls the amount of rice. When the rice conveying belt 2 stops moving, the L-shaped cutting and scraping plate 61 of the cutting and scraping plate assembly 6 moves downward to divide the rice in the cavity I. After the division is completed, the L-shaped cutting and scraping plate 61 moves along the direction of the rice outlet on the rice conveying belt 2 and sends the rice to the semi-enclosed structure formed between the L-shaped pushing plate 71 and the clamping plate II 32. At the same time, the L-shaped cutting and scraping plate 61 moves into the semi-enclosed structure to form the cavity II and compresses and shapes the rice in the cavity II. After the compression and shaping of the rice are completed, the L-shaped cutting and scraping plate 61 returns to the initial position through the two-degree-of-freedom mechanism, and the clamping plate II 32 also returns to the initial position through the driving component I 33. Finally, the pushing plate of the pushing plate assembly 7 pushes the shaped rice to the rice outlet to complete a rice serving process. By adopting the cutting and then extruding and shaping mode, the problem of inconsistent texture of the rice is solved, and the mixed rice of the rice that has been compressed and the rice that has not been compressed is avoided. The rice after each cutting is not compressed, and the semi-enclosed structure formed by the L-shaped cutting and scraping plate 61 of the cutting and scraping plate assembly 6, the clamping plate II 32 and the L-shaped pushing plate 71 of the pushing plate assembly 7. After the L-shaped cutting and scraping plate 61 extrudes and shapes the rice in the semi-enclosed structure, the tightness of the rice can be relatively consistent, and the taste and dining experience of the rice are improved.

By adopting this technical method, the food delivery plate assembly 4 drives the food delivery plate 41 to reciprocate in the transmission direction of the rice through the driving component II 42, and the movement speed of the food delivery plate 41 is consistent with the movement speed of the rice conveying belt 2. It is ensured that the rice can continuously and stably advance during the transmission process, and the accumulation or stagnation of the rice on the conveying belt is avoided, so that the smoothness and efficiency of the food delivery process are ensured.
