Description

Technical Field

[0001] This utility model relates to the field of liquid filling technology, and in particular to a liquid weighing and filling device. Background Technology

[0002] The liquid weighing filling system is an automated device used for quantitative filling of liquids in industries such as edible oil, lubricating oil, wine, beverages, and chemicals. Based on the fact that the density of these liquids remains constant, a strong correlation is established between weight and volume. During filling, the filling container is weighed in real time by a weighing platform. Filling stops once the specified weight has been reached, thus obtaining the corresponding volume of liquid.

[0003] Currently, the filling process described above mainly involves filling the liquid into the corresponding container from top to bottom. For example, the "real-time weighing liquid filling equipment" proposed in Chinese Utility Model No. CN222411033U includes: a filling platform; an automatic weighing platform, set on the filling platform, suitable for holding the filling barrel to obtain and send the weight data of the filling barrel in real time; a lifting mechanism, set on the filling platform; a filling nozzle, installed on the lifting mechanism, suitable for approaching the mouth of the filling barrel through the lifting mechanism; a material conveying component, connected to the filling nozzle; and a control module, electrically connected to the automatic weighing platform and the material conveying component respectively; wherein the filling nozzle is provided with a dust cover, suitable for covering the mouth of the filling barrel during filling; the control module is suitable for controlling the material conveying component to fill the filling barrel with material, and controlling the material conveying component to stop filling material when the obtained weight data reaches a threshold.

[0004] However, when filling from top to bottom, the liquid falling from the top will have an additional impact on the filling barrel due to gravity and the difference in height. This will cause the automatic weighing platform to be affected by the aforementioned impact when weighing in real time. This usually results in the weighing value being greater than the actual weight, which is not conducive to accurate weighing and quantitative filling. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a liquid weighing and filling device that can improve filling accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquid weighing and filling device, comprising a main liquid storage tank, a first conveying assembly, a liquid storage sub-tank, a second conveying assembly, a filling nozzle, a filling platform, and a control module; The filling platform has a barrel placement position for placing filling barrels. The filling platform is equipped with a first mounting frame, and the first mounting frame is equipped with a vertical moving track for the sub-tanks. The liquid storage sub-tanks are slidably mounted on the vertical moving track for the sub-tanks. The first mounting frame is also equipped with an automatic weighing platform; the automatic weighing platform is suitable for supporting and weighing the liquid storage tanks that are moving down from the tank vertical track, so as to obtain and send the weight data of the liquid storage tanks in real time. The main storage tank is connected to the sub-storage tank via the first conveying assembly, and the sub-storage tank is connected to the filling nozzle via the second conveying assembly. The filling nozzle is located above the container placement position. The control module is electrically connected to the first material conveying component, the second material conveying component, and the automatic weighing platform, respectively.

[0007] Further technical solution of this utility model: The first material conveying component includes a liquid supply pump, a first liquid supply pipe, and a second liquid supply pipe. One end of the liquid supply pump is connected to the main liquid storage tank through the first liquid supply pipe, and the other end of the liquid supply pump is connected to the sub-liquid storage tank through the second liquid supply pipe. The liquid supply pump is electrically connected to the control module.

[0008] A further technical solution of this utility model: the second liquid supply pipe is a flexible tube.

[0009] A further technical solution of this utility model: the first feeding assembly also includes a first solenoid valve, which is disposed on the second liquid supply pipe and used to control the opening / closing of the inside of the second liquid supply pipe; The first solenoid valve is electrically connected to the control module.

[0010] A further technical solution of this utility model: the filling nozzle is connected to the tank body of the liquid storage tank.

[0011] Further technical solution of this utility model: The second conveying component includes a conveying pipe and a second solenoid valve. One end of the conveying pipe is connected to the bottom of the liquid storage tank. The conveying pipe is arranged vertically. The other end of the conveying pipe is connected to the filling nozzle. The second solenoid valve is arranged on the conveying pipe and is used to control the opening / closing of the inside of the conveying pipe. The second solenoid valve is electrically connected to the control module.

[0012] Further technical solution of this utility model: The second conveying assembly also includes a pressure relief pipe and a third solenoid valve. The inner top of the liquid storage tank is connected to the outside of the liquid storage tank through the pressure relief pipe. The third solenoid valve is installed on the pressure relief pipe and is used to control the opening / closing inside the pressure relief pipe. The third solenoid valve is electrically connected to the control module.

[0013] Compared with the prior art, the beneficial effects of this technical solution are as follows: when filling the filling barrel, the automatic weighing platform obtains the weight of the liquid storage tank accordingly. When the liquid storage tank outputs liquid through the filling nozzle to fill the filling barrel, the fluctuation of the liquid outflow to the liquid storage tank is low, and the weight reduction output by the liquid storage tank can be determined more accurately. Correspondingly, even if the liquid impacts the filling barrel when it falls, the weight of the liquid filled into the filling barrel can be controlled better. That is, under the condition that the liquid density remains unchanged, the volume of liquid filled into the filling barrel can be controlled better.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0017] 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 protection scope of the present utility model.

[0018] Please see Figure 1 A liquid weighing and filling device includes a main liquid storage tank 1, a first conveying assembly, a secondary liquid storage tank 2, a second conveying assembly, a filling nozzle 3, a filling platform 4, and a control module.

[0019] The filling platform 4 has a barrel placement position 5 for placing filling barrels (not shown). The filling platform 4 is provided with a first mounting frame 6, and the first mounting frame 6 is provided with a tank vertical moving track 7. The liquid storage tank 2 is slidably mounted on the tank vertical moving track 7.

[0020] The first mounting frame 6 is also equipped with an automatic weighing platform 8; the automatic weighing platform 8 is suitable for supporting and weighing the liquid storage tank 2 as it moves down from the tank vertical moving track 7, so as to obtain and send the weight data of the liquid storage tank 2 in real time.

[0021] The main storage tank 1 is connected to the sub-storage tank 2 via the first conveying assembly, and the sub-storage tank 2 is connected to the filling nozzle 3 via the second conveying assembly. The filling nozzle 3 is located above the barrel placement position 5.

[0022] The control module is electrically connected to the first material conveying component, the second material conveying component, and the automatic weighing platform 8, respectively.

[0023] The control module (not shown) is adapted to control the first feeding component to feed materials into the liquid storage tank 2, and to control the first feeding component to stop feeding materials when the acquired weight data rises to the feeding threshold.

[0024] The control module is adapted to control the second feeding component to output material to the filling nozzle 3, and to control the second feeding component to stop outputting material when the acquired weight data drops to the filling threshold.

[0025] When filling the filling barrel, the automatic weighing platform 8 obtains the weight of the liquid storage tank 2. When the liquid storage tank 2 outputs liquid through the filling nozzle 3 to fill the filling barrel, the fluctuation of the liquid outflow to the liquid storage tank 2 is low, and the weight reduction output by the liquid storage tank 2 can be determined more accurately. Correspondingly, even if the liquid impacts the filling barrel when it falls, the weight of the liquid filled into the filling barrel can be controlled better. That is, with the liquid density remaining constant, the volume of liquid filled into the filling barrel can be controlled better.

[0026] In some embodiments, the filling nozzle is connected to the tank body of the liquid storage tank.

[0027] In some embodiments, the first feeding assembly includes a liquid supply pump 9, a first liquid supply pipe 10, and a second liquid supply pipe 11. One end of the liquid supply pump 9 is connected to the main liquid storage tank 1 through the first liquid supply pipe 10, and the other end of the liquid supply pump 9 is connected to the sub-liquid storage tank 2 through the second liquid supply pipe 11.

[0028] In some embodiments, the second supply tube 11 is a flexible tube.

[0029] In some embodiments, the first feeding assembly further includes a first solenoid valve 12, which is disposed on the second liquid supply pipe 11 and is used to control the opening / closing of the inside of the second liquid supply pipe 11.

[0030] In some embodiments, the second conveying assembly includes a conveying pipe 13 and a second solenoid valve 14. One end of the conveying pipe 13 is connected to the bottom of the liquid storage tank 2. The conveying pipe 13 is arranged vertically. The other end of the conveying pipe 13 is connected to the filling nozzle 3. The second solenoid valve 14 is arranged on the conveying pipe 13 and is used to control the opening / closing of the inside of the conveying pipe 13.

[0031] In some embodiments, the second conveying assembly further includes a pressure relief pipe 15 and a third solenoid valve 16. The inner top of the liquid storage tank 2 is connected to the outside of the liquid storage tank through the pressure relief pipe 15. The third solenoid valve 16 is disposed on the pressure relief pipe 15 and is used to control the opening / closing of the inside of the pressure relief pipe 15.

[0032] In this embodiment, the control module is electrically connected to the liquid supply pump 9, the first solenoid valve 12, the second solenoid valve 14, and the third solenoid valve 16.

[0033] During material distribution, the control module can control the operation of the liquid supply pump 9 and control the first solenoid valve 12 to open the second liquid supply pipe 11. The liquid supply pump 9 then delivers the liquid from the main storage tank 1 to the distribution tank 2. When the acquired weight data rises to the material delivery threshold, the control module stops the liquid supply pump 9 from delivering liquid and controls the first solenoid valve 12 to close the second liquid supply pipe 11. After the filling barrel is placed on the barrel placement position 5 of the filling platform, the control module can control the second solenoid valve 14 to open the inside of the conveying pipe 13 and control the third solenoid valve 16 to open the inside of the pressure relief pipe 15, so that the liquid storage tank 2 can fill the filling barrel; when the acquired weight data drops to the filling threshold, the second solenoid valve 14 is controlled to close the inside of the conveying pipe 13 and the third solenoid valve 16 is controlled to open the inside of the pressure relief pipe 15, so that the liquid storage tank 2 stops filling the filling barrel.

[0034] The difference between the feeding threshold and the filling threshold is the required filling weight.

[0035] In some embodiments, the control module has an operation interface that allows setting the aforementioned feeding threshold and filling threshold.

[0036] In some embodiments, the automated weighing platform may be, for example, an electronic scale.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
