Technical Field
[0001] This utility model belongs to the field of automatic rice weighing technology, and in particular relates to an automatic rice weighing and packaging device. Background Technology
[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, milling, and finishing. It is a staple food for people in southern China. Rice packaging is a very important step in the rice production process. During the packaging process, the rice bags need to be tightened, and the amount of rice needs to be quantitatively controlled to prevent overfilling.
[0003] The publication (announcement) number CN220577545U discloses an automatic rice weighing and packaging device, including a main body, a mounting frame, and a support frame. A servo motor is fixedly connected to one side of the front end of the mounting frame, and a drive roller is rotatably connected to one side of the front end of the mounting frame. Multiple driven rollers are rotatably connected to the side of the front end of the mounting frame away from the drive roller. In this utility model, a rice-filled packaging bag is placed inside the storage box, and the electromagnetic control valve of the discharge pipe is opened to fill the bag with rice. When enough rice is filled, the servo motor is activated to rotate the drive roller, and the driven rollers rotate synchronously with the drive roller via a drive belt, thereby driving the storage box forward. At the same time, a heating rod and a heat-conducting plate are used to heat-seal the packaging bag, thus making the automatic rice weighing and packaging device more stable during the rice filling process and preventing the rice from spilling.
[0004] The automatic rice weighing and packaging device works by placing a storage box 14 on the conveyor and placing the rice bags inside the storage box 14 to prevent the rice bags from spilling during transport. While this method solves the problem of rice bags spilling during transport, after the bags are sealed, the rice bags need to be removed from the storage box 14 and the storage box 14 needs to be placed back in front of the conveyor for transport again, resulting in low rice packaging efficiency. Therefore, an automatic rice weighing and packaging device needs to be designed to solve the above problems. Utility Model Content

[0007] Preferably, the inner cavity of the roller conveyor is connected to multiple rollers via a belt pulley drive. The bottom of the roller conveyor is provided with a base plate, and multiple connecting rods are welded to the bottom of the clamping plate. Sliding rods are slidably connected to the front and rear sides of the top of the base plate. The connecting rods extend through the gaps between the rollers to the bottom of the roller conveyor and are welded to the top of the sliding rods.
[0008] Preferably, multiple guide rails are symmetrically installed on both the front and rear sides of the top of the base plate, and a roller is installed at the bottom of the sliding rod, and the roller rolls on the surface of the guide rail.
[0009] Preferably, a sliding block is slidably connected to the top of the base plate, and a plurality of rotating rods are rotatably connected to the surface of the sliding block, with the end of the rotating rod away from the sliding block rotatably connected to the bottom of the sliding rod.
[0010] Preferably, a threaded rod is rotatably connected at the center of the top of the base plate, and the sliding block is threadedly connected to the surface of the threaded rod.
[0011] Preferably, a motor is fixedly installed on the top of the base plate, and the output shaft of the motor is fixedly connected to the threaded rod.
[0012] The beneficial effects of this utility model are:
[0013] 1. This utility model uses the combination of clamping plates and guide rollers.

[0020] In the following description, embodiments of the automatic rice weighing and packaging device of the present invention will be described with reference to the accompanying drawings.
[0021] Figure 1-2 This invention illustrates an embodiment of an automatic rice weighing and packaging device, comprising an automatic rice weighing machine 1 and a roller conveyor device 2. The automatic rice weighing machine 1 is located at the left end of the roller conveyor device 2, and a packaging bag sealing machine 4 is installed at the right end of the roller conveyor device 2. Clamping plates 5 are provided on both the front and rear sides of the top of the roller conveyor device 2, and multiple guide rollers 6 are installed on the top of the clamping plates 5. Multiple rollers 3 are connected to the inner cavity of the roller conveyor device 2 via a belt pulley. A base plate 7 is provided at the bottom of the roller conveyor device 2, and multiple connecting rods 8 are welded to the bottom of the clamping plates 5. Sliding rods 9 are slidably connected to both the front and rear sides of the top of the base plate 7. The connecting rods 8 extend through the gaps between the rollers 3 to the bottom of the roller conveyor device 2 and are welded to the top of the sliding rods 9. Multiple guide rails 10 are symmetrically installed on both the front and rear sides of the top of the base plate 7. A roller 11 is installed at the bottom and rolls on the surface of the guide rail 10. A sliding block 12 is slidably connected to the top of the base plate 7. Multiple rotating rods 13 are rotatably connected to the surface of the sliding block 12. The end of the rotating rod 13 away from the sliding block 12 is rotatably connected to the bottom of the sliding rod 9. Through the cooperation of the sliding block 12 and the rotating rod 13, the two sliding rods 9 can be pulled to slide symmetrically on the top of the base plate 7, thereby driving the clamping plate 5 to slide symmetrically on the top of the roller conveyor device 2, so that the guide roller 6 can center and clamp the rice packaging bag for easy sealing operation of the rice packaging bag sealing machine 4. A threaded rod 14 is rotatably connected to the center of the top of the base plate 7. The sliding block 12 is threadedly connected to the surface of the threaded rod 14. A motor 15 is fixedly installed on the top of the base plate 7. The output shaft of the motor 15 is fixedly connected to the threaded rod 14.
[0022] Working Principle: When using this utility model, the user places the rice packaging bag at the bottom of the discharge port of the automatic rice weighing machine 1. The clamping mechanism in the automatic rice weighing machine 1 clamps the packaging bag, and then the discharge port releases rice into the packaging bag. Afterwards, the roller 3 in the roller conveyor device 2 rotates, driving the rice packaging bag from the left end of the roller conveyor device 2 to the right end of the packaging bag sealing machine 4 for sealing. At this time, the guide roller 6 on the top of the clamping plate 5 clamps it to prevent the rice packaging bag from tipping over. When the size of the rice packaging bag changes, the motor 15 drives the threaded rod 14 to rotate on the top of the base plate 7, thereby driving the sliding block 12 to slide to the right. Then, the rotating rod 13 pulls the two sliding rods 9 to slide towards each other on the top of the guide rail 10. At this time, the clamping plate 5 will slide towards each other on the top of the roller conveyor device 2. Adjusting the distance between the two clamping plates 5 will adjust the distance between the two side guide rollers 6, realizing the clamping and conveying of rice packaging bags of different sizes.
[0023] In summary, this automatic rice weighing and packaging device, through the combined use of clamping plate 5 and guide roller 6, allows the guide roller 6 to clamp and guide the rice packaging bag when the roller conveyor 2 conveys and seals it, preventing it from tipping over. Furthermore, the sliding connection of clamping plate 5 enables the clamping and conveying of rice packaging bags of different sizes.
