This design ensures that the two additives are mixed evenly, avoiding local concentrations that are too high or too low, thereby improving the uniformity and stability of the product. The automated stirring process reduces the time and labor costs of manual stirring. A scale 15 is fixedly set on the outer wall of the mixing tank 3, which provides an intuitive liquid level indication. Operators can quickly understand the current liquid level of the materials in the mixing tank 3. This helps to accurately control the amount of materials added, avoiding over- or under-addition, and ensuring the accuracy and stability of the production process. A discharge pump 16 is fixedly connected to one side of the outer wall of the mixing tank 3.

This helps maintain a clean and safe production environment and reduces material waste.

[0033] Please see Figure 1 , Figure 3 and Figure 4A water inlet 19 is fixedly connected to one side of the upper end of the mixing tank 3. A first sealing cap 20 is threadedly connected to the upper end of the water inlet 19. The design of the water inlet 19 not only meets the water addition needs during the production process, but also has a cleaning function. Operators can easily add cleaning solution through the water inlet 19 and start the stirring device to thoroughly clean the inside of the mixing tank 3, keeping the production equipment clean and hygienic, and reducing the risk of material residue and contamination. A feeding port 21 is fixedly connected to one side of the upper end of the two raw material tanks 8. A second sealing cap 22 is threadedly connected to the upper end of the two feeding ports 21. The design of the feeding port 21 allows operators to easily add the required additives into the raw material box 8, ensuring a sufficient supply of additives during production and reducing the difficulty of adding additives.

This helps prevent additive leakage, maintains a clean and safe production environment, and avoids the volatilization and deterioration of additives during storage. A fixing plate 23 is fixedly connected to one side of the base plate 1, and a fixing post 24 is fixedly connected to the upper end of the fixing plate 23. A control console 25 is fixedly connected to the end.

The control console 25 is typically equipped with various control buttons, a display screen, and indicator lights, facilitating real-time monitoring and operation by the operator. The ends of two hoses 11 furthest from the extraction pump 10 are fixedly connected to the feed pipe 4. The hoses 11 act as a bridge connecting the extraction pump 10 and the feed pipe 4, ensuring smooth transport of the additive from the raw material tank 8 to the mixing tank 3 via the extraction pump 10. The precise extraction of the additives and the stable delivery of the hose 11 ensure that the dosage of the additives added to the mixing tank 3 is accurate each time. Since the two hoses 11 are connected to two different raw material tanks 8 respectively, the ratio of the two additives can be easily adjusted. This design allows the device to adapt to different production needs and flexibly adjust the emulsion formulation. The introduction of the hose 11 simplifies the operation process of adding the additives to the mixing tank 3. The operator only needs to start the extraction pump 10, and the additives will automatically enter the mixing tank 3 through the hose 11 and the feed pipe 4 without manual operation or additional equipment.

[0034] In this embodiment, the quantitative feeding device for additives in the production of acrylate emulsions is equipped with two feed pipes 4, each equipped with a flow meter 5 and a first solenoid valve 6. This allows for precise control and monitoring of the amount of each additive added, ensuring that the additive ratio is accurate and consistent in each production run, which helps improve product quality and stability. Through the extraction pipes 9 and extraction pumps 10 in the two raw material tanks 8, and the connected hoses 11, the device can efficiently transport the additives from the raw material tanks 8 to the mixing tank 3. This design reduces manual operation steps and improves production efficiency. By changing or adjusting the additives in the raw material tanks 8, and adjusting the settings of the flow meter 5 and the first solenoid valve 6, it can easily adapt to different production formulas and process requirements.

[0035] It should be noted that the mixing box 3 is made of acrylic material. Acrylic material has the characteristics of high transparency, light weight, good weather resistance and excellent processing performance. In the production process of acrylic emulsion, the high transparency of the mixing box 3 makes it easy for operators to observe the mixing situation and adjust the production parameters in a timely manner. At the same time, the weather resistance and processing performance of acrylic material also ensure the long-term stability and service life of the mixing box 3.

[0036] The working principle of the above embodiments is as follows:

[0037] The operator first adds the required additives to the two raw material tanks 8 through the feeding port 21, ensuring that the second sealing cap 22 is tightly closed to prevent additive leakage. Based on production needs, the operator adjusts the settings of the flow meter 5 and the first solenoid valve 6 via the control console 25 to determine the dosage of each additive. When production begins, the operator starts two extraction pumps 10, which extract the additives from the raw material tanks 8 through the extraction pipe 9. The additives are then transported to the feed pipe 4 via the hose 11. During this process, the flow meter 5 monitors and records the flow rate of the additives in real time to ensure the accuracy of the dosage. When the additives reach the feed pipe 4, the first solenoid valve 6 opens, allowing the additives to enter the mixing tank 3. Simultaneously, the motor 12 starts, driving the rotating shaft 13 and the stirring blades 14 to rotate. The stirring blades 14 then stir the mixture... The additives are thoroughly stirred and mixed inside the mixing tank 3. The operator can observe the liquid level of the material through the scale 15 on the outer wall of the mixing tank 3 to ensure that the amount added meets the production requirements. After mixing is completed, the operator starts the discharge pump 16, which outputs the mixed additives through the discharge pipe 17. The second solenoid valve 18 plays a control role in this process, ensuring that the passage of the discharge pipe 17 is cut off when discharge is not needed to prevent material leakage. Throughout the production process, the operator can monitor and operate the device in real time through the control buttons, display screen and indicator lights on the control console 25. After production is completed, the operator can add cleaning solution through the water inlet 19 and start the stirring device to clean the mixing tank 3 to keep the production equipment clean and hygienic.
