Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: Figure 1-Figure 4As shown, the utility model provides a technical solution, including a fixed box body 1, an L-shaped plate 2 is fixedly connected to the center of the top surface of the fixed box body 1, a T-shaped slide 3 is opened on the top surface of the fixed box body 1, two parallel T-shaped sliders 4 are slidably connected inside the T-shaped slide 3, and the top surfaces of the two T-shaped sliders 4 are fixedly connected to the movable plates 5, and the two movable plates 5 are provided with a limit mechanism 6 and a weighing assembly 7;

[0023] The limiting mechanism 6 includes two parallel sliding columns 61 and three evenly distributed limiting grooves 67. The two sliding columns 61 are fixedly connected to the top surface of the movable plate 5. The three limiting grooves 67 are all opened on the top surface of the fixed box 1. The top end of the sliding column 61 is coaxially fixedly connected to the limiting plate 62. The outer surfaces of the two sliding columns 61 are slidingly connected to the same movable rod 63. The outer surface of the sliding column 61 is provided with a spring 64. The center of the bottom surface of the movable rod 63 is fixedly connected to an insertion rod 65 that is compatible with the limiting groove 67. The top surface of the movable rod 63 is fixedly connected to a handle 66.

[0024] Further as Figure 1 、 Figure 3 and Figure 4 As shown, it is worth mentioning that the weighing assembly 7 includes two parallel supporting rods 71, both supporting rods 71 are fixedly connected to the top surface of the movable plate 5, the top surfaces of the two supporting rods 71 are fixedly connected to the same fixed annular plate 72, the inner surface of the fixed annular plate 72 is fixedly connected to a fixed cavity 73, the top of the fixed annular plate 72 is fixedly connected to a plurality of circumferentially distributed gravity sensors 74, the top surfaces of the plurality of gravity sensors 74 are fixedly connected to the same movable annular plate 75, the inner surface of the movable annular plate 75 is fixedly connected to a plurality of circumferentially distributed connecting sliders 76, the outer surface of the fixed cavity 73 is penetrated by a plurality of movable grooves 77 for the connecting sliders 76 to move, the plurality of connecting sliders 76 are fixedly connected to the same weighing hopper 78 through the plurality of movable grooves 77, the bottom end of the weighing hopper 78 is fixedly connected to a discharge pipe 79 that passes through the bottom end of the fixed cavity 73, the outer surface of the discharge pipe 79 is provided with a first solenoid valve 710, and the inner surface of the weighing hopper 78 is installed with a metal detector 711.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth mentioning that a storage bin 8 is fixedly connected to the outer wall of one end of the transverse section of the L-shaped plate 2, a discharge pipe 9 is fixedly connected to the bottom end of the storage bin 8, and a second solenoid valve 10 is provided on the outer surface of the discharge pipe 9.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth mentioning that a packaging integrated machine 11 is installed on the outer wall of one end of the fixed box body 1, and a controller 12 is fixedly connected to the outer wall of one side of the fixed box body 1.

[0027] Further as Figure 1、 Figure 2 and Figure 3 As shown, it is worth mentioning that the top and bottom ends of the spring 64 are fixedly connected to the bottom end of the limit plate 62 and the top surface of the moving rod 63 respectively, and the bottom end of the insertion rod 65 slides through the bottom surface of the moving plate 5 and is inserted into the corresponding limit groove 67. The elastic action of the spring 64 pushes the insertion rod 65 into the interior of the limit groove 67.

[0028] Further as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that one of the limit slots 67 located in the middle position is on the same axis as the discharge pipe 9. When a group of weighing components 7 moves to cooperate with the middle limit slot 67, the material flowing out of the discharge pipe 9 can accurately enter the weighing hopper 78. The gravity sensor 74, the first solenoid valve 710, the metal detector 711, the second solenoid valve 10 and the packaging all-in-one machine 11 are all electrically connected to the controller 12, so that the operator can better control the operation of the device.

[0029] In summary: when the device is in use, first turn on the power supply to put the device into working state, and set the gravity sensor 74, the first solenoid valve 710, the metal detector 711, the second solenoid valve 10 and the packaging machine 11 through the controller 12, and then put the material into the storage bin 8. The second solenoid valve 10 allows the material to pass through the discharge pipe 9 into the weighing hopper 78 in one group of weighing components 7. At this time, the material exerts downward pressure on the weighing hopper 78 under the action of gravity. Under the cooperation of the connecting slider 76 and the movable groove 77, the weighing hopper 78 is forced to move downward inside the fixed cavity 73, and at the same time The weighing hopper 78 drives the movable annular plate 75 to move downward, thereby pressing down the multiple gravity sensors 74. The data obtained after the gravity sensors 74 are subjected to force is displayed on the controller 12, thereby realizing the measurement of the material. At the same time, the metal detector 711 arranged inside the weighing hopper 78 performs metal detection on the material to ensure the safety of the material during subsequent packaging. The weighed material flows downward through the discharge pipe 79 under the control of the first solenoid valve 710, and the packaging of the material is completed under the operation of the packaging all-in-one machine 11. The measurement is accurate, which effectively avoids the problem of large quality errors affecting the packaging accuracy during packaging.

[0030] When the metal detector 711 inside a group of weighing hoppers 78 fails, the handle 66 on the movable plate 5 fixing the weighing hopper 78 is pulled upward, and the handle 66 drives the movable rod 63 to move upward on the outer surface of the slide column 61. At this time, the spring 64 on the slide column 61 is forced to shrink, and at the same time, the movable rod 63 drives the insertion rod 65 to separate from the limit groove 67 located in the middle position, releasing the limit of the movable plate 5, and then pushing the movable plate 5 to move toward one side of the fixed box body 1. When the movable plate 5 moves to a limit groove 67 located at one side position, the handle 66 is released and the insertion rod 65 is pushed into the limit groove 67 under the action of elasticity. The above operation is performed on the other group of weighing components 7 in the same way, and the other group of weighing components 7 is moved to the limit groove 67 located in the middle position, ensuring that the metal detector 711 in normal use can detect the material. The operation is simple and effectively avoids the problem that the metal detection equipment is easy to fail and affects the packaging efficiency.
