Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint production, in particular to a grinding device for water-based paint production with a pretreatment function. Background Art

[0002] Or natural water-based paints with minerals (such as potassium silicate) and petrochemical water-based paints with synthetic resins (such as acrylic resins). Water-based paints include three types: water-soluble paints, water-dilutable paints, and water-dispersible paints (latex paints). Among them, water-soluble paints use water-soluble resins as film-forming materials, such as polyvinyl alcohol and its various modifications, water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. Water-dilutable paints are paints formulated with emulsified emulsions as film-forming materials, dissolving solvent-based resins in organic solvents, and then with the help of emulsifiers, using strong mechanical stirring to disperse the resin in water to form an emulsion. The resulting paint can be diluted with water during construction.

The partition plate 2 is fixedly connected to both sides of the middle of the cabinet 1 to separate the drying chamber 102 from the grinding chamber 101, thereby ensuring the independence of the two processes. The drying chamber 102 provides a controllable drying environment for the material, ensuring that the material reaches an appropriate degree of dryness before grinding. The bottom of the stirring shaft 402 is rotatably connected to the middle of the partition plate 2, the output end of the motor 1 401 is fixedly connected to the upper surface of the stirring shaft 402, one end of the stirring bar 403 is fixedly connected to the stirring shaft 402, and one side of the stirring blade 404 is fixedly connected to the other end of the stirring bar 403. There are four stirring bars 403 and four stirring blades 404, and the stirring bars 403 are cross-arranged on the stirring shaft 402, which together constitute a stirring system for uniformly mixing materials during the drying process, ensuring that the materials are heated evenly and improving the drying efficiency. The feed opening 201 is opened on both sides of the stirring shaft 402, and the front and rear ends of the rotating plate 501 are rotatably connected to the feed opening 201 through the connecting bar 1 503, and the rotating plate 501 is tightly fitted with the feed opening 201. The feed opening 201 allows materials to enter the grinding chamber 101 from the drying chamber, while the rotating plate 501 and the connecting bar 1 503 ensure the controllability and accuracy of the feed. The handle 502 is fixedly connected to one end of the connecting strip 503, and the electric heating tube 8 is arranged between the outer wall and the inner wall of the drying chamber 102. There are multiple electric heating tubes 8 to provide the heat required for drying. They are fixedly connected between the outer wall and the inner wall of the drying chamber 102 at equal intervals to ensure uniform temperature distribution in the drying chamber 102.

The grinding chamber 101 provides a closed and controllable grinding environment for the material to ensure the stability and efficiency of the grinding process. The bottom of the mixing drum 601 is fixedly connected to the inner bottom surface of the cabinet 1. As the main component of the grinding chamber 101, it contains the materials required for grinding. The annular groove 602 is opened on the inner wall of the mixing drum 601, and the bottom of the rotating block 701 is rotatably connected to the inner bottom surface of the mixing drum 601. The annular placement groove 704 is opened on the outer side of the rotating block 701. There are two groups of annular grooves 602 and annular placement grooves 704, and the annular grooves 602 correspond to the annular placement grooves 704.

The rolling block 702 is connected to the inside of the annular placement groove 704 through the connecting strip 2 703. A plurality of rolling blocks 702 are fixedly connected to the inside of the annular placement groove 704. The outward side of the rolling block 702 is in contact with the inner wall of the annular groove 602. The fine grinding of the material is achieved through the rotation of the rotating block 701 and the rolling action of the rolling block 702.

[0032] Working principle: The water-based paint raw material is put into the drying chamber 102 through the feeding bin 3. The motor 1 401 and the electric heating tube 8 are started. The motor 1 401 is started, driving the stirring shaft 402, the stirring bar 403 and the stirring blade 404 to rotate, stirring the material so that the material is evenly distributed in the drying chamber 102. At the same time, the electric heating tube 8 provides heat to dry the material. By turning the handle 502 to drive the rotating plate 501 to rotate, the discharge port 201 is opened, and the material enters the grinding chamber 101. In the grinding chamber 101, the motor 2 7 is started to drive the rotating block 701 to rotate. The rolling block 702 on the outside of the rotating block 701 rotates accordingly, and cooperates with the annular groove 602 on the inner wall of the mixing drum 601 to finely grind the material. Due to the close cooperation between the rolling block 702 and the annular groove 602, the material is effectively pushed and mixed while being rolled, thereby improving the grinding efficiency and grinding quality. After the grinding is completed, the discharge port of the grinding chamber 101 is opened to collect the ground water-based paint product.
