Description

Technical Field

[0001] This utility model relates to the field of water-based coating production technology, specifically to an intelligent compounding and mixing device for water-based coatings. Background Technology

[0002] The compounding of water-based coatings is a core and essential step in the production process. Its essence lies in scientifically combining components such as resins, additives, pigments, and fillers to address the inherent defects of water-based systems and optimize performance. For example, Chinese patent application CN2023212464995 discloses a water-based coating mixing device that uses a dual-shaft motor as a power source to synchronously drive the first and second rotating rods, thereby causing the mixing tank and the stirring paddle to rotate in opposite directions, thus accelerating the mixing efficiency. However, this solution still has the following technical defects: firstly, the traditional fixed stirring mechanism design makes it easy for water-based coatings to separate, resulting in poor coating compounding uniformity and severely affecting the compounding effect; secondly, the dual-shaft motor needs to simultaneously drive both the stirring paddle and the mixing tank, resulting in a large workload and making the dual-shaft motor prone to damage, leading to high maintenance costs. Therefore, this case arose from in-depth research into these problems. Utility Model Content

The top cover 2 integrates a transmission control component, which, together with the drive control component, can realize the synchronous rotation control of multiple sets of impact stirring components, thereby improving the impact stirring effect of the coating. A liquid temperature probe is installed in the tank 1 to realize real-time monitoring of the temperature of the water-based coating liquid.

[0017] In specific implementation, the aforementioned transmission control assembly includes an annular seat 10, a rotating ring 11, and a gear ring 12. The annular seat 10 is fixedly installed in the annular cavity 3. The outer ring of the rotating ring 11 is fixedly connected to the annular seat 10. The gear ring 12 is nested on the inner ring of the rotating ring 11. A drive gear 13 is installed in the annular cavity 3. The drive gear 13 meshes with the gear ring 12 and is connected to the drive control assembly through a connecting shaft 14. Several output shafts 15 are arranged in annular array in the annular cavity 3. A driven gear 16 is fitted on the output shaft 15. The driven gear 16 meshes with the gear ring 12. The lower end of the output shaft 15 is connected to the impact stirring assembly. The drive control assembly includes a bracket 17, a drive motor 18, and a reducer 19.

In use, the drive motor 18 and the reducer 19 work together to drive the connecting shaft 14. The rotation of the connecting shaft 14 drives the drive gear 13 to rotate. The rotation of the drive gear 13 drives the gear ring 12 to rotate. The rotation of the gear ring 12 drives the output shaft 15 and the driven gear 16 to rotate synchronously.

[0018] In practical implementation, the aforementioned intelligent temperature control structure includes a high-temperature water tank 23, a transition water tank 24, and a cold water tank 25. A three-way inlet valve 26 is installed at the inlet end of the jacket structure. One inlet of the three-way inlet valve 26 is connected to the high-temperature water tank 23 via a booster pump 27, and the other inlet is connected to the cold water tank 25 via a water supply pump 28. The outlet end of the jacket structure is connected to the transition water tank 24 via a three-way drain valve 29, and one outlet of the three-way drain valve 29... The end is connected to the high-temperature water tank 23, which is equipped with a heater 30. A water temperature sensor 31 is installed on one side of the heater 30. A replenishment pump 32 is installed between the high-temperature water tank 23 and the transition water tank 24. When the water-based coating compounding process requires the liquid to be heated to 40-50 degrees Celsius, the water in the high-temperature water tank 23 is heated by the heater 30, and the water temperature is monitored by the water temperature sensor 31. The booster pump 27 is started to pump the high-temperature water through the three-way inlet valve. 26 is injected into the jacket structure, where it exchanges heat with the liquid. The temperature of the liquid is monitored by a temperature probe. After heat exchange, the low-temperature water is returned to the high-temperature water tank 23 via a three-way drain valve 29. The temperature of the water in the jacket structure is monitored by a temperature sensor. The data monitored by the temperature probe, temperature sensor, and water temperature sensor 31 are all transmitted to the controller via electrical signals. The controller controls the heating power of the heater 30 and the water supply power of the booster pump 27, thereby realizing intelligent regulation of the liquid temperature. After the compounding operation is completed, the booster pump 27 stops working and the opening and closing directions of the three-way inlet valve 26 and the three-way drain valve 29 are adjusted. The low-temperature water in the cold water tank 25 is injected into the jacket structure through the water supply pump, thereby achieving rapid cooling of the water-based coating. The heated water flows into the transition water tank 24. The warm water in the transition water tank 24 can be injected into the high-temperature water tank 23 or other equipment such as the boiler water tank through the replenishment pump 32.
