Description

Technical Field

[0001] This utility model relates to the technical field of coating mixing devices, specifically a water-based coating mixing device. Background Technology

[0002] In the production process of water-based coatings, the mixing stage is a critical step that determines product quality. Currently, coating mixing equipment has many drawbacks: manual material changes require frequent disassembly and reassembly of pipelines to switch raw materials, which is cumbersome and easily contaminates the raw materials, making it difficult to adapt to the flexible production needs of multiple formulations and small batches; raw material feeding relies on manual measurement, resulting in large dosage errors, which leads to unstable coating formulation ratios and affects the consistency of product performance.

[0003] With the advancement of environmental protection policies and the increasing market demands for coating quality, enterprises urgently need an intelligent mixing device capable of precise material control and adaptability to multiple formulations. While existing technologies attempt to optimize the mixing structure, they still fall short in terms of raw material classification and storage, and precise dispensing coordination, failing to fundamentally solve the problems of low efficiency and large errors caused by manual intervention. Therefore, those skilled in the art have provided a water-based coating mixing device to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a water-based coating mixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The storage tank is mounted on the top plate and is rotatably connected to the top plate. The storage tank has several storage chambers, each containing a different water-based coating. Each storage chamber has a discharge port 2 at its lower end, and an electrically controlled valve 2 is fixedly installed on each discharge port 2. Each storage chamber has a feed port 2 at its upper end.

With the help of servo motor 2 driven by sprocket-chain transmission, the discharge port 2 of any storage chamber can be accurately rotated to the top of the inlet 1 of the mixing tank. Compared with manual material changing and adding, there is no need to frequently disassemble and reassemble the pipeline. It is suitable for multi-formula production scenarios and improves material changing efficiency and material selection flexibility.

[0013] 2.

Each discharge port 29 is fixedly equipped with an electrically controlled valve 20. Each storage chamber 21 has a feed inlet 22 at its upper end. A central shaft 18 is fixedly connected to the center of the lower end of the storage tank 24. A driven sprocket 17 is provided on the outer wall of the central shaft 18, and the driven sprocket 17 is fixedly connected to the central shaft 18. A servo motor 23 is fixedly installed on the upper end of the top plate 6. A rotating shaft 24 is fixedly connected to the power output end of the servo motor 23, and the rotating shaft 24 is rotatably connected to the top plate 6 and the connecting... On the frame 4, a main sprocket 15 is installed on the outer wall of the rotating shaft 14. The main sprocket 15 is fixedly connected to the rotating shaft 14. A chain 16 is installed between the main sprocket 15 and the driven sprocket 17. One end of the chain 16 is engaged with the main sprocket 15, and the other end is engaged with the driven sprocket 17. A sealing cap 23 is threaded onto the feed inlet 22. A support base 2 is fixedly connected to the upper end of the base 3. A mixing tank 1 is fixedly connected to the upper end of the support base 2. A control device is fixedly installed on one side of the mixing tank 1. The mixing tank 1 and the top plate 6 are fixedly connected by two support rods on the left and right. A servo motor 7 is fixedly installed on the upper end of the mixing tank 1. A rotating shaft 8 is fixedly connected to the power output end of the servo motor 7. Several sets of stirring rods 9 are fixedly connected to the outer wall of the rotating shaft 8. The rotating shaft 8 and the stirring rods 9 are located inside the mixing tank 1. A feed inlet 10 is opened at the upper end of the mixing tank 1, and a discharge outlet 11 is opened at the lower end of the mixing tank 1. An electrically controlled valve 12 is fixedly installed on the discharge outlet 11.

[0023] The working principle of this utility model is as follows: When raw materials are fed in, firstly, the servo motor 13 is started to drive the rotating shaft 14 to rotate. The rotating shaft 14 drives the main sprocket 15 to rotate. The main sprocket 15 drives the driven sprocket 17 to rotate via the chain 16. The driven sprocket 17 drives the central shaft 18 to rotate. The central shaft 18 drives the storage tank 24 to rotate. In this way, the discharge port 19 of any storage chamber 21 in the storage tank 24 can be precisely rotated above the inlet 10 of the mixing tank 1, realizing the orderly preparation for the feeding of different types of water-based coatings. Then, each discharge port 19 of the storage chamber 21 is equipped with an electrically controlled valve 20, which can be individually controlled by sending instructions through the controller 5. The valve opening and closing time, based on the volume of the storage chamber 21 and the valve flow rate characteristics, precisely controls the amount of water-based coating discharged from the storage chamber 21 into the mixing tank 1, meeting the strict requirements of different formulations for raw material ratios. During coating mixing and stirring, the servo motor 7 is started to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the stirring rod 9 to rotate in the mixing tank 1. The stirring rod 9 forms shearing, convection, and diffusion effects through mechanical contact with the coating. The shearing force breaks the interface of the coating liquid layer, promoting the fusion of different components. The convection makes the coating circulate in the tank, eliminating local concentration differences. The diffusion assists in the uniform mixing at the molecular level, ultimately achieving uniform mixing of various water-based coatings and ensuring consistent product quality.
