Description

Technical Field

[0001] The present application relates to the technical field of rice dumpling production equipment, and in particular to an automatic feeding device and method for sandwich rice dumplings. Background Art

[0002] In the food processing industry, especially for the production of traditional festival foods such as zongzi, the application of automated equipment is becoming more and more widespread. This not only improves production efficiency and reduces labor costs, but also significantly improves the consistency and stability of product quality. Zongzi, as a traditional Chinese food, usually needs to wrap rice and other ingredients (such as red bean paste, meat filling, etc.) together to form a unique taste and flavor. However, with the growth of market demand, the traditional manual production method has been difficult to meet the needs of large-scale production. Therefore, the development of efficient and stable automated feeding devices has become an urgent need. At present, there are many automated equipment for zongzi production on the market, mainly focusing on the following aspects: first, automatic packaging of zongzi is achieved through robotic arms or conveyor belts; second, the use of mixers and quantitative distribution systems to achieve uniform mixing and packaging of rice materials; third, the visual inspection system is used to ensure the quality of zongzi. Although these devices can improve production efficiency to a certain extent, there are still some shortcomings in actual applications. For example, some equipment performs poorly in the uniform distribution and precise measurement of rice materials, resulting in unstable quality of the final product; and some equipment cannot achieve fast and accurate multiple feeding when processing sandwich zongzi, affecting the overall production efficiency.

[0003] Existing automatic feeding devices usually use a metering mechanism to complete the entire feeding process, which is particularly inconvenient when processing sandwich rice dumplings. Specifically, after the metering mechanism completes one feeding, it needs to wait for the sandwich raw materials to be put in before feeding a second time. This not only increases the operation time, but may also cause uneven distribution of rice materials, affecting the quality of the rice dumplings. In addition, since each feeding needs to be restarted and stopped, the operating efficiency of the equipment is also limited. Therefore, how to design an automatic device that can quickly and continuously complete two feedings is a technical problem that needs to be solved urgently. Summary of the invention

[0004] In order to help improve the feeding efficiency of packaged stuffed rice dumplings, the present application provides an automatic feeding device for stuffed rice dumplings.

[0016] By adopting the above technical solution, the metering mechanism cooperates with the mounting hole on the side wall of the fuselage through the mounting frame to ensure that the metering hopper is stably set outside the fuselage, which is convenient for feeding and feeding operations. The metering hopper is set correspondingly to the feeding port of the feeding tray to ensure that the rice raw material is accurately fed into the metering hopper.

When the weight of the rice raw material of the zongzi reaches a first preset weight in one of the metering mechanisms, a corresponding feeding mechanism stops feeding; when the weight of the rice raw material of the zongzi reaches a second preset weight in another metering mechanism, another corresponding feeding mechanism stops feeding; S4. The mold cavity of the packaged rice dumplings is placed in one of the feed ports of the metering mechanism, the feed port is opened for the first feeding, the feed port is closed after the first feeding is completed, and a corresponding feeding mechanism starts feeding work until the metering mechanism completes the next cycle of metering work; S5.

[0024] By adopting the above technical scheme, the automatic feeding method can realize efficient feeding of sandwich rice dumplings. Specifically, the stirring mechanism fully stirs the rice raw materials of the rice dumplings to ensure the uniformity and consistency of the raw materials. At the same time, the rice raw materials are evenly pushed to the two feeding ports for feeding through stirring to prevent the rice raw materials from sticking and accumulating at the feeding ports, thereby improving the accuracy of subsequent measurement; the two feeding mechanisms are respectively connected to the two feeding ports and the corresponding metering mechanisms, thereby realizing independent feeding and metering of the two metering mechanisms and improving the feeding efficiency; the feeding is carried out through the feeding mechanism to ensure the uniform transportation of the rice raw materials and further improve the metering accuracy; the weighing sensor in the metering mechanism monitors the weight of the rice raw materials in real time, and when the preset weight is reached, the feeding mechanism stops feeding to ensure accurate control of each feeding; after the first feeding is completed, the sandwich raw materials are immediately placed, followed by the second feeding, and the two feeding processes are closely connected, thereby improving the continuity and efficiency of the entire feeding process; through the interlocking connection method, the actions of each component are ensured to be coordinated and consistent, thus avoiding operating errors and improving the stability and reliability of the system.

[0044] The embodiment of the present application also discloses a method for automatically feeding sandwich rice dumplings.

The feeding actions of the two metering mechanisms are interlocked and connected in sequence. Specifically, one metering mechanism can only feed after one metering mechanism has finished feeding. The feeding mechanism is interlocked with the corresponding metering mechanism. Specifically, the metering mechanism is measuring during the feeding process, and when the preset weight is reached, the feeding mechanism stops feeding.

[0047] The automatic feeding method can realize efficient feeding of sandwich rice dumplings, specifically: the stirring mechanism 2 fully stirs the rice raw materials of the rice dumplings to ensure the uniformity and consistency of the raw materials and improve the accuracy of subsequent measurement; the two feeding mechanisms 4 are respectively connected to the two feeding ports 211 and the corresponding metering mechanisms 3, realizing independent feeding and metering of the two metering mechanisms 3 and improving the feeding efficiency; the feeding is carried out by the feeding mechanism 4 to ensure the uniform transportation of the rice raw materials and further improve the metering accuracy; the weighing sensor 34 in the metering mechanism 3 monitors the weight of the rice raw materials in real time, and when the preset weight is reached, the feeding mechanism 4 stops feeding to ensure accurate control of each feeding; after the first feeding is completed, the sandwich raw materials are placed immediately, followed by the second feeding, and the two feeding processes are closely connected, which improves the continuity and efficiency of the entire feeding process; through the interlocking connection method, it is ensured that the actions of each component are coordinated and consistent, avoiding operating errors and improving the stability and reliability of the system.

[0048] The implementation principle of the automatic feeding device for sandwich rice dumplings in the embodiment of the present application is as follows: the rice raw materials for rice dumplings are uniformly stirred by the stirring mechanism 2, and then the two feeding mechanisms 4 are respectively fed through the two feeding ports 211. The two feeding mechanisms 4 respectively convey the rice raw materials to the two metering mechanisms 3, which accurately meter the rice raw materials to ensure the accuracy of each feeding. The two metering mechanisms 3 feed the same sandwich rice dumplings to be packaged in turn. When one metering mechanism completes the feeding, the sandwich raw materials are placed on the rice raw materials fed in for the first time, and then the other metering mechanism feeds again, so that the two feedings of the same sandwich rice dumplings to be packaged can be completed quickly, and the rice raw materials supplied twice can wrap the sandwich raw materials, thereby improving the feeding efficiency of the sandwich rice dumplings to be packaged. This design not only improves production efficiency, but also ensures the quality and consistency of the rice dumplings.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application in sequence. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
