Abstract
Description
Technical Field
[0001] This application relates to the field of rice packaging technology, and in particular to a quantitative automated rice packaging device. Background Technology
[0002] Rice is a finished product made from paddy through cleaning, hulling, milling, and finishing processes. Rice contains nearly 64% of the nutrients found in paddy and over 90% of the nutrients required by the human body, and is a staple food for people in most parts of China. Currently, rice is usually packaged before sale. The packaging process typically involves filling rice into bags and then sealing them. However, rice filling is usually controlled by a single solenoid valve, which makes it difficult to uniformly control the amount of rice filled. Furthermore, some rice may spill during filling, hindering subsequent packaging. Therefore, to solve these problems, this application provides a quantitative automated rice packaging device. Utility Model Content
[0003] To address the problem that controlling the filling volume is inconvenient with a single solenoid valve, this application provides a quantitative automated rice packaging device.
[0004] This application provides a quantitative automated rice packaging device, including a storage bin with multiple support legs fixedly connected to its bottom. A feeding hopper is located on one side of the storage bin, and the feeding hopper is connected to the storage bin via a conveying pipe. A first solenoid valve is installed on the conveying pipe. A feeding pipe is fixedly connected to the bottom of the feeding hopper, and a second solenoid valve is installed on the feeding pipe. An automatic filling assembly is provided on the feeding hopper, including a guide rod movably installed inside the feeding hopper. A movable plate is fixedly connected to the bottom of the guide rod, and a limit plate is fixedly connected to the top of the guide rod. A first contact switch is fixedly installed below the limit plate, and a second contact switch is fixedly installed on the top inner side of the feeding hopper.
[0005] Preferably, the injection hopper is located at the bottom of one side of the storage silo, and the inside of the injection hopper is hollow.
[0006] Preferably, the guide rod is vertically disposed inside the injection hopper, and the top end of the guide rod extends to the outside of the injection hopper.
[0007] Preferably, the movable plate is horizontally disposed inside the injection hopper, and the movable plate has multiple through holes.
[0008] Preferably, the end of the injection pipe extends into the inside of the injection hopper, and the injection pipe is located at the middle position of the bottom of the injection hopper.
[0009] In summary, this application includes the following beneficial technical effects:
[0010] By designing an automatic filling component, during rice packaging, rice is fed into the filling hopper through a conveying pipe. This causes a movable plate to move to the top of the inner side of the filling hopper, triggering a second contact switch. At this point, the feeding of rice into the filling hopper stops, and the filling process continues through the conveying pipe. After filling, the movable plate loses its bottom support and moves downward, triggering a first contact switch. This stops the filling process again, and the rice is fed into the filling hopper through the conveying pipe, facilitating the next filling cycle. Compared to existing technologies, this design enables automatic quantitative filling of rice, preventing spillage during filling and simplifying subsequent packaging. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.
[0017] Example:
[0018] A quantitative automated rice packaging device is used for the automatic quantitative packaging of rice, as described above. Figure 1 - Figure 2The device includes a storage silo 1, which facilitates the loading of rice for packaging. Multiple support legs 2 are fixedly connected to the bottom of the storage silo 1, allowing for easy installation of the device. A feeding hopper 3 is located on one side of the storage silo 1, facilitating the loading of pre-packaged rice. The feeding hopper 3 is located at the bottom of one side of the storage silo 1 and is hollow inside. The feeding hopper 3 is connected to the storage silo 1 via a conveying pipe 4, allowing rice from inside the storage silo 1 to flow into the feeding hopper 3 through the conveying pipe 4. The feeding hopper 3 also facilitates subsequent pre-packaged filling. A first solenoid valve 5 is installed on the conveying pipe 4 to control the opening and closing of the conveying pipe 4. A feeding pipe 6 is fixedly connected to the bottom of the feeding hopper 3. The end of the feeding pipe 6 extends into the inside of the feeding hopper 3 and is located in the middle of the bottom of the feeding hopper 3. The feeding pipe 6 facilitates the injection of rice into the packaging bag. A second solenoid valve 7 is installed on the feeding pipe 6 to control the opening and closing of the feeding pipe 6. An automatic filling component is provided on the feeding hopper 3 to facilitate the automatic filling of rice, thereby facilitating subsequent packaging.
[0019] During processing, the rice to be packaged is loaded into the storage silo 1. During subsequent filling, the automatic filling component controls the operation of the equipment, and the rice is fed into the filling hopper 3 through the conveying pipe 4. The first solenoid valve 5 controls the opening and closing of the conveying pipe 4, and the second solenoid valve 7 controls the opening and closing of the filling pipe 6, so that the rice in the filling hopper 3 is quantitatively injected into the packaging bag through the filling pipe 6, thereby completing the automated filling of rice.
[0020] Reference Figure 3 - Figure 4 The automatic filling assembly includes a guide rod 8, which is movably installed inside the filling hopper 3, allowing it to reciprocate within the hopper. The guide rod 8 is vertically positioned inside the filling hopper 3, with its top extending to the outside of the hopper. A movable plate 9 is fixedly connected to the bottom of the guide rod 8, and is horizontally positioned inside the filling hopper 3. The movable plate 9 has multiple through holes 10 for easy handling of rice at the top. A limit plate 11 is fixedly connected to the top of the guide rod 8, limiting its range of motion. A fixed device is installed below the limit plate 11. A first contact switch 12 is installed to control the opening of the first solenoid valve 5 and the closing of the second solenoid valve 7. A second contact switch 13 is fixedly installed on the top inner side of the feeding hopper 3 to control the closing of the first solenoid valve 5 and the opening of the second solenoid valve 7. In the idle part of this device, all the above-mentioned electrical components, which refer to power components, electrical components and matching controllers and power supplies, are connected by wires. For specific connection methods, refer to the working principle below, where the electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are known in the art.
[0021] During filling, rice is fed into the filling hopper 3 through the conveying pipe 4. The rice inside the filling hopper 3 continuously pushes the movable plate 9 and guide rod 8 to move, causing the movable plate 9 to move to the top of the inner side of the filling hopper 3, thereby triggering the second contact switch 13. The second contact switch 13 controls the closing of the first solenoid valve 5 and the opening of the second solenoid valve 7, stopping the feeding of rice into the filling hopper 3, and filling the rice inside the filling hopper 3 through the filling pipe 6. After filling is completed, the movable plate 9 loses its bottom support and moves downward, causing the limiting plate 11 to contact the top of the filling hopper 3, thereby triggering the first contact switch 12. The first contact switch 12 controls the opening of the first solenoid valve 5 and the closing of the second solenoid valve 7, stopping the filling of rice, and feeding rice into the filling hopper 3 through the conveying pipe 4, facilitating the next filling.
[0022] This application discloses a quantitative automated rice packaging device. The working principle is as follows: During processing, the rice to be packaged is loaded into the storage hopper 1. During subsequent filling, the rice is fed into the filling hopper 3 via the conveying pipe 4. The rice fed into the filling hopper 3 continuously pushes the movable plate 9 and guide rod 8, causing the movable plate 9 to move to the top of the inner side of the filling hopper 3, thereby triggering the second contact switch 13. The second contact switch 13 controls the closing of the first solenoid valve 5 and the opening of the second solenoid valve 7, stopping the feeding of rice into the filling hopper 3. The rice is then filled into the filling hopper 3 via the filling pipe 6. After filling, the movable plate 9 loses its bottom support and moves downwards, causing the limiting plate 11 to contact the top of the filling hopper 3, thereby triggering the first contact switch 12. The first contact switch 12 controls the opening of the first solenoid valve 5 and the closing of the second solenoid valve 7, stopping the filling of rice. The rice is then fed into the filling hopper 3 via the conveying pipe 4, facilitating the next filling cycle.
