[0025] Figure 1 This invention discloses a heat-insulating rice receiving plate assembly for an automatic food vending machine, comprising a pair of rice clamping plates 1 arranged below the rice storage box, a pair of rice blocking plates 13 arranged at the front end of the rice clamping plates 1, and a rice conveying component 6 arranged below the rice clamping plates 1. The rice clamping plates 1, rice blocking plates 13, and rice conveying component 6 form a cavity for accommodating rice in space. The assembly also includes steam components arranged on both sides of the rice clamping plates 1. Each rice clamping plate 1 has a double-layer structure with an internal space for accommodating steam. One side of each rice clamping plate 1 has multiple through holes I2 communicating with the cavity, and the other side of each rice clamping plate 1 has through holes II3 communicating with the steam outlet of the steam component.

[0026] Working principle:

[0027] First, the rice falls from the storage box into the rice clamping plate 1. The rice baffle 13 and the rice conveying component 6 form a cavity to accommodate the rice. Simultaneously, as the rice enters the cavity, the steam component starts operating, generating steam that enters the internal space of the rice clamping plate 1 through the through-hole II3. This steam accumulates in the internal space of the rice clamping plate 1 and flows into the cavity formed by the rice clamping plate 1, the rice baffle 13, and the rice conveying component 6 through the through-hole I2. Because the rice clamping plate 1 has a double-layer structure, the flow and diffusion of steam within the internal space can be effectively controlled, thus achieving uniform heating of the rice.

[0028] As steam flows through the cavity, the rice is heated by the steam, maintaining a certain temperature and humidity. This heating method not only prevents the rice from drying out and hardening due to a drop in temperature during cooking, but also ensures the texture and flavor of the rice.

[0029] The above solution also includes: a rice receiving plate 4, which is disposed between the rice clamping plates 1. The rice receiving plate 4 has a U-shaped structure, passes through the side wall of one side of the rice clamping plate 1, and its front end extends into the space between the rice clamping plates 1. The rear end of the rice receiving plate 4 is connected to the output shaft of the cylinder.

[0030] The rice receiving plate 4 and the rice conveying component 6 are provided with a certain gap in terms of spatial height.

[0031] Using this technology, when the meal serving begins, the rice inside the rice storage box starts to fall downwards. The rice receiving plate 4, driven by the output shaft 5 of the cylinder at the rear, moves forward, creating a space between the rice receiving plate 4 and the rice clamping plate 1 to hold the rice. Simultaneously, there is a certain gap between the rice receiving plate 4 and the rice conveying component 6. After the rice falls into the rice receiving plate 4, the output shaft 5 drives the rice receiving plate 4 to move backwards, causing the rice to fall from the rice receiving plate 4 onto the rice conveying component 6. This effectively avoids the problem of insufficient gap between the rice and the rice conveying component, which could prevent subsequent rice from falling. This design indeed improves the efficiency of rice conveying.

[0032] In the above scheme, the two clamping plates 1 are connected by a connecting component, which includes: ball screws 7 arranged in pairs at the front and rear ends of the clamping plates 1. The front and rear ends of each clamping plate 1 are connected to slider seats 8 on the ball screws 7 via connecting parts. The two ball screws 7 are connected by a synchronous belt 9. The slider seats 8 on the ball screws 7 are arranged opposite each other, and one of the ball screws 7 is connected to the output shaft of the output motor. Using this technical method, firstly, the two ball screws 7 are respectively arranged at the front and rear ends of the clamping plates 1, and are arranged in pairs facing each other. As a high-precision transmission component, the ball screw 7 has excellent straightness and wear resistance, and can provide stable and precise movement control.

[0033] Both ends of the rice clamping plate 1 are connected to the slider seat 8 on the ball screw 7 via connectors. This means that when the ball screw 7 rotates, the slider seat 8 will move linearly along the ball screw 7, thereby driving the rice clamping plate 1 to move accordingly. This connection method ensures both stable movement of the rice clamping plate 1 and precise position control.

[0034] The two ball screws 7 are connected by a synchronous belt 9. The synchronous belt 9 has the advantages of smooth transmission, low noise, and high transmission efficiency, which can ensure that the two ball screws 7 rotate synchronously, thereby ensuring that the movement of the rice clamping plate 1 at both ends is consistent.

[0035] One of the ball screws 7 is connected to the output shaft of the output motor. The output motor provides power to the ball screw 7, and by driving the rotation of the ball screw 7, the rice clamping plate 1 is moved. Because the ball screw 7 has high transmission precision, the movement of the rice clamping plate 1 is also very precise and smooth.

[0036] During operation, when the output motor starts, it drives the connected ball screw 7 to rotate. Through the transmission of the synchronous belt 9, the other ball screw 7 also rotates synchronously. As the ball screw 7 rotates, the slider seat 8 moves linearly along the ball screw 7, thereby causing the rice clamping plate 1 to move accordingly. The direction and speed of movement of the rice clamping plate 1 can be controlled by adjusting the rotation direction and speed of the output motor.

[0037] In the above scheme, the steam component includes: a hot water tank 10 disposed at the bottom of the rice conveying component 6, and a steam nozzle 11 disposed on the frame;

[0038] The hot water tank 10 and the steam nozzle 11 are connected by a rigid connecting pipe 12. The size of the steam nozzle 11 is smaller than the size of the through hole II 3, and the steam nozzle 11 extends into the internal area of ​​each rice clamping plate 1, with a certain gap reserved between them in space. Using this method, the hot water tank 10 is placed at the bottom of the rice conveying component 6 to store heated water. When the water in the hot water tank 10 is heated to boiling, a large amount of steam is generated. This steam then flows to the steam nozzle 11 through the rigid connecting pipe 12.

[0039] The rigid connecting pipe 12 ensures smooth steam flow from the hot water tank 10 to the steam nozzle 11, while reducing steam loss during transmission and improving energy efficiency.

[0040] The steam nozzle 11 is mounted on the frame and its size is smaller than that of the through hole II 3, ensuring that the steam nozzle 11 can pass through the through hole II 3 and extend into the internal space of the rice clamping plate 1. A certain gap is reserved between the steam nozzle 11 and the through hole II 3 to ensure that the steam nozzle 11 and the rice clamping plate 1 will not interfere with each other in terms of spatial position when the rice clamping plate 1 moves left and right, and also to ensure that the steam can be sprayed out from the nozzle evenly and cover the internal space of the rice clamping plate 1.

[0041] When steam is ejected from the steam nozzle 11, it enters the internal space of the rice clamping plate 1 through the through hole II3, heating and moisturizing the rice. Due to the double-layer structure and through-hole design of the rice clamping plate 1, the steam can be evenly distributed around the rice, ensuring that the rice remains hot and moist throughout the sales process.

[0042] In this way, the steam component provides continuous heating and moisture retention for the rice, improving its texture and flavor, while also ensuring that the rice maintains a suitable temperature for an extended period of time.

[0043] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
