[0004] A novel, precise, automated liquid dispensing device is proposed to address the aforementioned problems. Utility Model Content
[0005] The purpose of this invention is to provide an automatic liquid dispensing device with precise measurement, so as to solve the problem mentioned in the background art that it is impossible to automatically and accurately dispense liquids as much as possible.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic liquid dispensing device for precise metering, comprising a guide box, with support columns fixedly connected to both ends of the bottom sides of the guide box, a base plate fixedly connected to the bottom end of the support columns, a feed inlet fixedly connected to the top end of the guide box, and a metering mechanism for automatic precise metering provided at the top end of the base plate.
[0007] The measuring mechanism includes a weighing scale, with the weighing scale fixedly connected to the top of the base plate, a weighing plate fixedly connected to the top of the weighing scale, a placement groove opened at the top of the weighing plate, and a controller fixedly connected to one end of the weighing scale.
[0008] As a further technical solution of this utility model, the center line of the weighing plate and the center line of the guide box are on the same vertical plane, and the placement slots opened at the top of the weighing plate are arranged at equal intervals.
[0009] As a further technical solution of this utility model, a fixed cylinder is fixedly connected to both sides inside the material guide box, a rotating shaft is movably connected inside the fixed cylinder, a stirring rod is fixedly connected to the outside of the rotating shaft, a reducer is fixedly connected to the left side of the material guide box, and a drive motor is fixedly connected to the left side of the reducer.
[0010] As a further technical solution of this utility model, the output end of the drive motor is fixedly connected to the input end of the reducer, and the output end of the reducer passes through the left side of the guide box and extends into the interior of the fixed cylinder and is fixedly connected to the rotating shaft.
[0011] As a further technical solution of this utility model, the stirring rods outside the rotating shaft are arranged at equal intervals, and the center line of the rotating shaft and the center line of the guide box are on the same vertical plane.
[0012] As a further technical solution of this utility model, a fixed cover is fixedly connected to the bottom end of the guide box, four sets of discharge valves are fixedly connected to the bottom end of the guide box, a discharge pipe is fixedly connected to the bottom end of the discharge valve, a control gear is movably connected to the front end of the discharge valve, a drive shaft is movably connected inside the fixed cover, a drive gear is fixedly connected to the front end of the drive shaft, support sleeves are fixedly connected to the front ends of both sides inside the fixed cover, a transmission gear plate is movably connected inside the support sleeve, and a servo motor is fixedly connected to the front end of the fixed cover.
[0013] As a further technical solution of this utility model, the discharge pipe passes through the bottom end of the fixed cover and extends to the outside of the fixed cover, and the transmission gear plate is meshed with the drive gear and the control gear respectively.
[0014] As a further technical solution of this utility model, the output end of the servo motor passes through the front end of the fixed cover and is fixedly connected to the drive shaft, and the discharge valve is connected to the inside of the guide box.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the automatic liquid distribution device with precise metering not only achieves automatic and precise metering and maintains the fluidity of the liquid, but also achieves automatic control of multiple discharge structures to maintain uniform distribution.
[0016] By setting up a weighing scale, controller, weighing plate, placement tank and servo motor, multiple sets of storage containers are placed inside the placement tank when dispensing liquid. Then, multiple sets of discharge valves are opened at the same time to discharge the liquid. The weighing scale at the bottom can automatically weigh the liquid as it is poured into the container. When the weight of the dispensed liquid reaches the specified value, the controller automatically transmits a signal to the servo motor. The servo motor automatically closes multiple sets of discharge valves to stop dispensing, so that accurate measurement can be achieved during dispensing.
[0017] The system is equipped with a rotating shaft, stirring rod, reducer, drive motor, and fixed cylinder. Before dispensing the liquid, the liquid is added into the feed box through the inlet. Then, the drive motor is started, which drives the rotating shaft to rotate through the reducer. As the rotating shaft rotates, it drives the stirring rod outside the shaft to rotate. The stirring rod can automatically stir the liquid inside the feed box to keep the liquid inside the feed box fluid and prevent the liquid inside the feed box from being too viscous, which would affect the discharge speed. This achieves the goal of maintaining the fluidity of the liquid inside the feed box.
[0018] By incorporating a fixed cover, discharge valve, drive gear, drive shaft, discharge pipe, transmission gear plate, control gear, support sleeve, and servo motor, the system works as follows: When distributing liquid, the servo motor is activated, which drives the drive gear to rotate via the drive shaft. The drive gear, in turn, drives multiple sets of control gears to rotate synchronously via the transmission gear plate. This opens multiple discharge valves simultaneously, allowing liquid to be discharged through the discharge pipe. Once the discharge is complete, the servo motor is activated again to synchronously close the multiple discharge valves, stopping the discharge process and ensuring uniform distribution.

[0026] The measuring mechanism includes a weighing scale 11, a weighing scale 11 is fixedly connected to the top of the base plate 10, a weighing plate 13 is fixedly connected to the top of the weighing scale 11, a placement groove 14 is opened at the top of the weighing plate 13, and a controller 12 is fixedly connected to one end of the weighing scale 11.
[0027] The center line of the weighing plate 13 and the center line of the guide box 1 are on the same vertical plane, and the placement slots 14 opened at the top of the weighing plate 13 are arranged at equal intervals.
[0028] Specifically, such as Figure 1 and Figure 3 As shown, when distributing liquid, multiple sets of storage containers are placed inside the placement tank 14, and then multiple sets of discharge valves 15 are opened simultaneously to discharge liquid. While the liquid is being poured into the containers, the weighing scale 11 at the bottom can automatically weigh it. When the weight of the distributed liquid reaches the specified value, the controller 12 automatically transmits a signal to the servo motor 22, and the servo motor 22 automatically closes the multiple sets of discharge valves 15 to stop discharging, thereby enabling accurate measurement during distribution and achieving automatic and precise measurement.
[0029] The inside of the feed box 1 is fixedly connected to both sides of the fixed cylinder 7, the inside of the fixed cylinder 7 is movably connected to the rotating shaft 2, the outside of the rotating shaft 2 is fixedly connected to the stirring rod 4, the left side of the feed box 1 is fixedly connected to the reducer 5, and the left side of the reducer 5 is fixedly connected to the drive motor 6.
[0030] The output end of the drive motor 6 is fixedly connected to the input end of the reducer 5. The output end of the reducer 5 passes through the left side of the guide box 1 and extends into the interior of the fixed cylinder 7 and is fixedly connected to the rotating shaft 2.
[0031] The stirring rods 4 outside the rotating shaft 2 are arranged at equal intervals, and the center line of the rotating shaft 2 and the center line of the guide box 1 are on the same vertical plane;
[0032] Specifically, such as Figure 1 As shown, before distributing the liquid, the liquid is added into the feed box 1 through the feed inlet 3. Then, the drive motor 6 is started and drives the rotating shaft 2 to rotate through the reducer 5. While the rotating shaft 2 is rotating, it drives the stirring rod 4 outside to rotate. The stirring rod 4 can automatically stir the liquid inside the feed box 1 to keep the liquid inside the feed box 1 fluid and prevent the liquid inside the feed box 1 from being too viscous and affecting the discharge speed. This achieves the goal of maintaining the fluidity of the liquid inside the feed box 1.
[0033] A fixed cover 8 is fixedly connected to the bottom of the guide box 1. Four sets of discharge valves 15 are fixedly connected to the bottom of the guide box 1. A discharge pipe 18 is fixedly connected to the bottom of the discharge valve 15. A control gear 20 is movably connected to the front end of the discharge valve 15. A drive shaft 17 is movably connected inside the fixed cover 8. A drive gear 16 is fixedly connected to the front end of the drive shaft 17. Support sleeves 21 are fixedly connected to the front ends of both sides inside the fixed cover 8. A transmission gear plate 19 is movably connected inside the support sleeve 21.

[0036] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, when distributing liquid, the servo motor 22 is started to drive the drive gear 16 to rotate through the drive shaft 17. The drive gear 16 drives multiple sets of control gears 20 to rotate synchronously through the transmission gear plate 19, thereby opening multiple sets of discharge valves 15 synchronously and discharging the liquid through the discharge pipe 18 at the same time. After the discharge is completed, the servo motor 22 is started again to synchronously close multiple sets of discharge valves 15 and stop the discharge at the same time, so as to maintain uniform distribution and achieve uniform distribution.
[0037] Working Principle: In use, before dispensing the liquid, it is added to the feed box 1 through the inlet 3. Then, the drive motor 6 is started, driving the rotating shaft 2 via the reducer 5. Simultaneously, the rotating shaft 2 rotates, causing the external stirring rod 4 to rotate. The stirring rod 4 automatically stirs the liquid inside the feed box 1, maintaining its fluidity and preventing it from becoming too viscous and affecting the discharge speed. During liquid dispensing, the servo motor 22 is started, driving the drive gear 16 via the drive shaft 17. The drive gear 16, through the transmission gear plate 19, drives multiple sets of control gears 20 to rotate synchronously. Multiple sets of discharge valves 15 are opened simultaneously to discharge material through discharge pipe 18. After discharge is completed, servo motor 22 is started to close multiple sets of discharge valves 15 simultaneously to stop discharge, so as to maintain uniform distribution. When distributing liquid, multiple sets of storage containers are placed inside the placement tank 14, and then multiple sets of discharge valves 15 are opened simultaneously to discharge liquid. While the liquid is being poured into the container, the weighing scale 11 at the bottom can automatically weigh it. When the weight of the distributed liquid reaches the specified value, the controller 12 automatically transmits the signal to the servo motor 22, and the servo motor 22 automatically closes multiple sets of discharge valves 15 to stop discharge, so that accurate measurement can be achieved during distribution.
