Description

Technical Field

[0001] This utility model relates to the field of electroplated aluminum colorant production technology, specifically a precision metering tank for dispensing materials in the production of electroplated aluminum colorants. Background Technology

[0002] In the production of electroplated aluminum colorants, the batching process is one of the key steps affecting product quality. Water, as a crucial component, directly impacts the concentration, stability, and final performance of the colorant through the precision of its addition. Currently, the industry commonly uses metering tanks as the core equipment for batching electroplated aluminum colorant production. These tanks contain, mix, and quantitatively add water and other ingredients, while a stirring structure ensures uniform mixing, providing the foundation for subsequent colorant processing. Due to their integrated batching capabilities, these metering tanks have become standard equipment on electroplated aluminum colorant production lines.

[0003] However, in the actual water addition operation of existing batching and metering tanks in the production of electroplated aluminum colorants, manual control is still the main method. Workers need to judge the water addition progress by observing the water level scale or relying on a single weighing. However, when observing manually, visual errors are easily caused by the influence of light and the concave liquid surface. Even with the aid of weighing, excessive water is often added due to the lag in manually closing the valve. Whether it is insufficient water addition leading to excessively high colorant concentration and affecting the uniformity of coating, or excessive water addition leading to excessively low concentration and reducing the coloring effect, it will disrupt the accurate proportion of the batching, affect the performance of the colorant, make it difficult to meet the production precision requirements, and may also increase the rework rate and interfere with continuous production.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please refer to Figures 1-4 This utility model discloses a precision metering tank for the production of electroplated aluminum colorant, comprising a mixing tank 1 and a base 2. The mixing tank 1 is a mixing structure used for mixing electroplated aluminum colorant, and the base 2 is a bottom structure used for supporting the overall structure. The top of the mixing tank 1 is connected to an inlet, and the bottom side of the mixing tank 1 is connected to an outlet. Both the inlet and outlet are switched by solenoid valves. The ingredients for preparing the colorant and water are added to the mixing tank 1 through the inlet, and discharged through the outlet after mixing is completed. The mixing tank 1 has a rotating spiral blade 13 inside, and a motor 14 is installed on one side of the mixing tank 1. The output end of the motor 14 is connected to the spiral blade 13, and the motor 14 drives the spiral blade 13 to rotate, thereby stirring and mixing the materials inside. The motor 14 is a servo motor, and its speed can be adjusted by an external control system to adapt to the stirring requirements of different materials.

[0019] A first weighing plate 22 is provided on the inner side of the base 2. A protruding post 11 is provided on the inner side of the bottom of the mixing tank 1. The bottom of the protruding post 11 contacts the weighing surface of the first weighing plate 22. Limiting rods 12 are provided around the bottom of the mixing tank 1, and limiting tubes 21 are provided around the top of the base 2. The limiting rods 12 and the limiting tubes 21 are connected in a lifting and sliding manner, so that the mixing tank 1 can be vertically lifted and lowered on the top of the base 2. The protruding post 11 presses against the weighing surface of the first weighing plate 22. Before adding water, the first weighing plate 22 weighs all the structures above in advance, so that the weight of water can be obtained when adding water. A metering component is provided on the upper rear side of the base 2. The metering component includes a mounting groove 23. A second weighing plate 24 is provided on the bottom inner side of the mounting groove 23. The top of the 23 is equipped with a hexagonal column 3 that is lifted and slidably installed. A measuring tank 31 is installed on the top of the hexagonal column 3. The top of the measuring tank 31 is opened and closed by a cover. The bottom of the hexagonal column 3 is in contact with the weighing surface of the second weighing plate 24. That is, the upper structure is weighed in advance by the second weighing plate 24. In order to remove the weight of the cover on the top of the measuring tank 31, the cover on the top of the measuring tank 31 is only closed after water is added. When water is added to the measuring tank 31, the weight of the water in the measuring tank 31 can be obtained. The measuring tank 31 is made of a transparent and corrosion-resistant material, such as polytetrafluoroethylene, so that the staff can directly observe the water volume inside. The inner side of the tank wall is equipped with scale lines, and the scale unit corresponds one-to-one with the weighing weight, which can be used as an auxiliary reference for weighing data. The bottom of the metering tank 31 is connected to an addition pipe 32 and a discharge pipe 34 on its front and rear sides, respectively. The addition pipe 32 and the discharge pipe 34 are switched by a solenoid valve. A flexible hose 33 is connected to the front of the addition pipe 32. A connecting pipe 15 is connected to the top rear of the mixing tank 1. The front of the flexible hose 33 is connected to the addition pipe 32. The capacity of the metering tank 31 can be set to 1 kg of water. If 10 kg of water needs to be added, the weighing weight of the first weighing plate 22 for water is set to 9 kg. When the first weighing plate 22 detects that the water is equal to or exceeds 9 kg, the inlet automatically closes. At this time, water is added to the metering tank 31 and is connected to the first weighing plate 22. The weighing plate 22 fully measures the weight of the water in the mixing tank 1. By subtracting this weight from 10kg, the required amount of water is obtained. Water is then added to the metering tank 31, and the water volume is monitored in real time by the second weighing plate 24. Water addition is stopped when the appropriate amount is reached. Even if too much water is added, the excess water is drained by opening the drain pipe 34. The weight is detected by the second weighing plate 24, and the drain pipe 34 is closed when the appropriate weight is reached. Then, the adding pipe 32 is opened to allow all the water in the metering tank 31 to enter the mixing tank 1, thereby ensuring the accuracy of water addition and avoiding adding too much or too little water.

[0020] A PLC controller is installed on one side above the base 2 to control all electrical equipment. All equipment has been pre-tested, which is a standard technical method for those skilled in the art. The PLC controller is equipped with a touch screen that can display the weighing data of the first weighing plate 22 and the second weighing plate 24 in real time, as well as the working status of each solenoid valve and motor 14. It also supports manual input of the target batching weight. The system automatically completes the batching process, making it easy to operate. The model of the first weighing plate 22 can be AVIC Electric Measurement H3F-100kg, the model of the second weighing plate 24 can be AVIC Electric Measurement H3F-10kg, the model of the motor 14 can be Panasonic MSMD022G1U, the model of the inlet and outlet solenoid valves can be Airtac 2W160-15, the model of the solenoid valves of the adding pipe 32 and the discharging pipe 34 can be Airtac 2W100-10, and the model of the PLC controller can be Siemens S7-1200.

[0021] The working principle of this utility model is as follows: the ingredients for preparing the colorant and water are added to the mixing tank 1 through the feed inlet. The motor 14 drives the spiral blades 13 to rotate, thereby stirring and mixing the internal materials. Before adding water, the first weighing plate 22 weighs all the structures above in advance, so as to obtain the weight of water when adding water. If 10kg of water needs to be added, the weighing weight of the water on the first weighing plate 22 is set to 9kg. When the first weighing plate 22 detects that the water is equal to or exceeds 9kg, the feed inlet is automatically closed. At this time, water is added to the metering tank 31, and the first... Weighing plate 22 fully measures the weight of the water in mixing tank 1. By subtracting this weight from 10kg, the required amount of water is obtained. Water is then added to metering tank 31, and the water volume is monitored in real time by second weighing plate 24. Water addition is stopped when the appropriate amount is reached. Even if too much water is added, the excess water is drained by opening drain pipe 34. The weight is detected by second weighing plate 24, and the drain pipe 34 is closed when the appropriate weight is reached. Then, adding pipe 32 is opened to allow all the water in metering tank 31 to enter mixing tank 1, thereby ensuring the accuracy of water addition and avoiding adding too much or too little water.
