[0021] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
[0022] See also Figure 1-3 The utility model is an automatic weighing and filling device, including a weighing mechanism, a discharging mechanism and a classification mechanism. The weighing mechanism includes an electronic balance 2, a connecting piece and a barrel 6. The electronic balance 2 is connected to the barrel 6 by a connecting piece. The barrel 6 is a hollow structure. The discharging mechanism includes a bracket 4, a first rotary cylinder 9 and a flap 7. The first rotary cylinder 9 is installed at one end of the bracket 4, and the output end of the first rotary cylinder 9 is fixedly connected to one end of the flap 7. The classification mechanism includes a support plate 12, a discharging device, a second rotary cylinder 14, a first discharging hopper 16 and a second discharging hopper 17. The discharging device is rotatably connected to the top of the support plate 12, and the discharging device is located directly below the barrel 6. The first discharging hopper 16 and the second discharging hopper 17 are arranged side by side below the support plate 12. The second rotary cylinder 14 is installed at the bottom of the support plate 12 to drive the discharging device to rotate.
[0023] In this embodiment, the connecting part includes a frame 1 and a connecting rod 3. The frame 1 is a rectangular frame structure. The electronic balance 2 is installed in the middle of the frame 1. One end of the connecting rod 3 is fixedly connected to the bottom of the frame 1, and the other end of the connecting rod 3 is movably connected to the barrel 6. Through the setting of the connecting part, the electronic balance 2 can weigh the material in the barrel 6.
[0024] In this embodiment, a feeding chute 5 is fixedly connected to the top of one side of the barrel 6, so that the chemical material slowly vibrates into the barrel 6 through the feeding chute 5, and the electronic balance 2 weighs the weight of the material in the barrel 6 in real time. When the material weight meets the production requirements, the feeding chute 5 stops vibrating and feeding, and the barrel 6 contains the material required for production. At this time, the flap 7 is in a closed state.
[0025] In some other embodiments, a spring hinge 8 is installed at the bottom of the other side of the barrel 6, and the flap 7 is rotatably connected to the barrel 6 through the spring hinge 8. A counterweight 10 is fixedly connected to the end of the flap 7 away from the barrel 6. When the spring hinge 8 is in the initial state, the bottom of the flap 7 fits seamlessly with the bottom of the barrel 6.
[0026] In this embodiment, the discharger includes a funnel 11 and a base. The funnel 11 is inserted into the top of the base. The base is rotatably connected to the top of the support plate 12. A discharge pipe 15 is fixedly connected to the bottom of the base. One end of the discharge pipe 15 is connected to the bottom of the funnel 11, and the other end of the discharge pipe 15 passes through the bottom of the support plate 12. The output end of the second rotary cylinder 14 is fixedly connected to the bottom of the base through a coupling 13.
[0027] It should be noted that the default position of the discharge pipe 15 is above the second discharge hopper 17. During the production process, in order to prevent the residual material in the upper trough 5 from entering the barrel 6 and causing the material weight to exceed the standard, the electronic balance 2 weighs the material weight again. If the weight meets the production requirements, the second rotary cylinder 14 is activated, the funnel 11 and the discharge pipe 15 are rotated, and the discharge pipe 15 is rotated to the top of the first discharge hopper 16, and then the first rotary cylinder 9 is activated to open the flap 7, so that the qualified material is discharged from the first discharge hopper 16 for collection; if the weight does not meet the production requirements, the second rotary cylinder 14 does not act, and the position of the discharge pipe 15 continues to be above the second discharge hopper 17. At this time, the first rotary cylinder 9 is activated to open the flap 7, so that the unqualified material is discharged from the second discharge hopper 17.
[0028] To sum up, after the raw material weighing and the position confirmation of the discharge pipe 15 are completed, the first rotary cylinder 9 is actuated to rotate the flap 7 from a parallel state to a vertical state. The force of the first rotary cylinder 9 overcomes the elastic force of the spring hinge 8 and the gravity of the counterweight block 10, so that the flap 7 rotates open, and the raw materials in the barrel 6 are poured into the funnel 11. Under the action of gravity, the raw materials are loaded into the first discharge hopper 16 or the second discharge hopper 17 through the discharge pipe 15.
[0029] In addition, the first rotary cylinder 9 and the second rotary cylinder 14 used in the utility model are both MSQB20A rotary cylinders, and the actions of the two cylinders are controlled by a PLC controller. The PLC controller model adopts the S7-1200 model PLC controller. Controlling the cylinder action by a PLC controller belongs to the public prior art.
[0030] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
