[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-6As shown, a finished rice packaging machine includes a conveyor 1. Several bases 2 are equidistantly fixed on the conveyor belt of the conveyor 1. A forming box 3 is positioned above the bases 2. A fixed frame 4 is fixedly connected to the top of the frame of the conveyor 1. An electric push cylinder 5 is fixedly connected to the center of the fixed frame 4. A mounting plate 7 is fixedly connected to the drive end of the electric push cylinder 5. A bagging assembly 6 is installed below the mounting plate 7. The bagging assembly 6 includes four sets of elastically telescopic extrusion rods 61. The top ends of the extrusion rods 61 are fixedly installed at the four corners of the lower surface of the mounting plate 7. The inner wall of the forming box 3 is symmetrically provided with raised layers. 8. The raised layer 8 is triangular. A rice bag 14 is fitted on the outside of the forming box 3. T-shaped limiting posts 15 are respectively installed on both sides of the bottom of the forming box 3. The bottom of the limiting posts 15 is fixedly connected to the base 2. The extrusion rod 61 is located above the four corners of the inner side of the forming box 3. The extrusion rod 61 includes a lower rod body. A spring telescopic rod is fixedly connected to the upper end of the lower rod body. The extrusion rod 61 can elastically contract under the extrusion of the forming box 3 when the forming box 3 is lifted in the future. A rice box 9 containing rice is installed above the conveying device 1. A discharge port is installed at the bottom of the rice box 9. A screw conveyor 10 is fixedly installed at the discharge port.

[0027] Specifically, the limiting post 15 is used to limit the molding box 3 to prevent it from tipping over. The raised layer 8 restricts the rice bag 14 to form V-shaped folds on both sides when it is moved into the molding box 3. In use, the rice bag 14 is first put on the outside of the molding box 3. Then, the molding box 3 with the rice bag 14 is conveyed to the bottom of the fixed frame 4 by the conveying device 1. The electric push cylinder 5 extends and drives the mounting plate 7 to descend, so that the extrusion rod 61 presses down and pushes the upper surface of the rice bag 14 into the molding box 3, thereby setting the rice bag 14 inside the molding box 3, which facilitates the installation of the rice bag 14. Then, the screw conveyor 10 quantitatively conveys rice into the rice bag 14, adding rice into the rice bag 14.

[0028] The bagging assembly 6 also includes two sets of rotating plates 62. Rotating seats 63 are rotatably connected to both sides of the rotating plates 62 via shafts. The bottom end of the rotating seats 63 is fixedly connected to the frame of the conveying equipment 1. A pressure sensor 64 is fixedly connected to the upper surface of one end of the rotating plate 62. The bagging assembly 6 also includes two long rods 65. The top end of the long rods 65 is fixedly connected to the lower surface of the mounting plate 7. A counterweight is provided on the lower side of the rotating plate 62 near the pressure sensor 64 to increase the gravity at that end and make the end of the rotating plate 62 with the pressure sensor 64 tilt downward.

[0029] Specifically, the rotating seat 63 is used to rotate and support the rotating plate 62. When the mounting plate 7 descends, it drives the long rod 65 to descend. When the long rod 65 descends, its bottom end abuts against the rotating plate 62 and pushes the end of the rotating plate 62 on which the pressure sensor 64 is installed to rotate upward and abut against the forming box 3. It also pushes the forming box 3 to slide upward and leave a gap between it and the base 2. Thus, the weight of the rice in the rice bag 14 inside the forming box 3 can be detected by the pressure sensor 64. When the weight reaches a predetermined value, the controller controls the screw conveyor 10 to stop conveying, thereby realizing the quantitative addition of rice.

[0030] The molding box 3 includes a lower box body 31 and an upper box body 32. The upper surface of the protruding layer 8 connected to the inner side of the lower box body 31 is fixedly connected with several positioning holes 33. The lower surface of the protruding layer 8 connected to the inner side of the upper box body 32 is fixedly connected with several positioning posts 34. The protruding layer 8 is made of ferromagnetic material.

[0031] Specifically, by inserting the positioning pin 34 into the positioning hole 33, the lower box 31 and the upper box 32 are connected to form the molded box 3.

[0032] A fixed frame 11 is fixedly connected to the top of the frame of the conveying equipment 1. An electric push cylinder 12 is fixedly connected to the center of the fixed frame 11. A heat sealing assembly 13 is installed at the drive end of the electric push cylinder 12. The heat sealing assembly 13 includes a U-shaped mounting frame 131. The drive end of the electric push cylinder 12 is fixedly connected to the upper surface of the mounting frame 131. A connecting rod 133 is symmetrically fixedly connected to the inner top wall of the mounting frame 131. An electromagnet 134 is fixedly connected to the bottom end of the connecting rod 133. Electric push cylinders 132 are fixedly connected to both sides of the mounting frame 131. A heat sealing plate 135 is fixedly connected to the drive end of the electric push cylinder 132. A heating element is provided inside the heat sealing plate 135 to heat the heat sealing plate 135. Before sealing, the rice bag 14 can be vacuumed by a vacuum device. The vacuum device is existing technology and will not be described in detail here.

[0033] Specifically, after the rice is added, the forming box 3 is conveyed to the bottom of the fixed frame 11 by the conveying device 1. The electric push cylinder 12 extends and pushes the mounting frame 131 down, so that the electromagnet 134 abuts against the raised layer 8. By running the electromagnet 134 to attract the raised layer 8, the electromagnet 134 and the raised layer 8 connected to the upper box 32 are magnetically attracted and connected. Then, the electric push cylinder 12 retracts a certain distance, so that there is a certain gap between the lower box 31 and the upper box 32, and the heat sealing plate 135 moves to the gap. The electric push cylinder 132 extends and pushes the heat sealing plate 135 to move, so that the two heat sealing plates 135 abut against the rice bag 14 to heat seal the rice bag 14. After sealing, the electric push cylinder 132 retracts and returns to its original position. The electric push cylinder 12 extends again to make the positioning post 34 insert and cooperate with the positioning hole 33, and then disconnects the electromagnet 134. Finally, the electric push cylinder 12 retracts and returns to its original position.

[0034] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Furthermore, appropriate controllers should be selected and electrically connected to the electric push cylinder 1 (5), electric push cylinder 2 (12), electric push cylinder 3 (132), pressure sensor 64, conveying equipment 1, electromagnet 134, heat-sealing plate 135, and screw conveyor 10, according to the actual situation, to meet control requirements. The specific connections and control sequence should refer to the working principle described below, where the electrical connections are completed according to the sequential working order of each electrical component. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of the electrical control.

[0035] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0036] Working principle: When in use, the rice bag 14 is first placed on the outside of the forming box 3. Then, the forming box 3 with the rice bag 14 is conveyed to the bottom of the fixed frame 4 by the conveying device 1. The electric push cylinder 5 extends and drives the mounting plate 7 to descend, so that the extrusion rod 61 presses down and pushes the upper surface of the rice bag 14 into the forming box 3, thereby placing the rice bag 14 inside the forming box 3, which facilitates the installation of the rice bag 14. Then, the screw conveyor 10 quantitatively conveys rice into the rice bag 14, adding rice into the inside of the rice bag 14.

[0037] When the mounting plate 7 descends, it drives the long rod 65 to descend as well. When the long rod 65 descends, its bottom end abuts against the rotating plate 62, and pushes the end of the rotating plate 62 on which the pressure sensor 64 is installed to rotate upward and abut against the forming box 3. This pushes the forming box 3 to slide upward, leaving a gap between it and the base 2. Thus, the weight of the rice in the rice bag 14 inside the forming box 3 can be detected by the pressure sensor 64. When the weight reaches a predetermined value, the controller controls the screw conveyor 10 to stop conveying, thereby realizing the quantitative addition of rice.

[0038] After the rice is added, the forming box 3 is conveyed to the bottom of the fixed frame 11 by the conveying device 1. The electric push cylinder 12 extends and pushes the mounting frame 131 down, so that the electromagnet 134 abuts against the raised layer 8. The electromagnet 134 attracts the raised layer 8, so that the electromagnet 134 and the raised layer 8 connected to the upper box 32 are magnetically attracted and connected. Then, the electric push cylinder 12 retracts a certain distance, so that there is a certain gap between the lower box 31 and the upper box 32, and the heat sealing plate 135 moves to the gap. The electric push cylinder 132 extends and pushes the heat sealing plate 135 to move, so that the two heat sealing plates 135 abut against the rice bag 14 to heat seal the rice bag 14. After sealing, the electric push cylinder 132 retracts and returns to its original position. The electric push cylinder 12 extends again to make the positioning post 34 insert and cooperate with the positioning hole 33, and then disconnects the electromagnet 134. Finally, the electric push cylinder 12 retracts and returns to its original position.
