[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0020] like Figures 1 to 3As shown, a specific embodiment of the present invention discloses a mixing impeller for paint processing, including a support plate 100, wherein a plurality of first stirring blades 110 and a plurality of second stirring blades 120 are fixedly provided on the outer wall of the support plate 100; the first stirring blades and the second stirring blades are arranged in an array around the central circumference of the support plate, and the first stirring blades and the second stirring blades are staggered and spaced apart; a feed port 111 is provided on the first stirring blade 110, and a side of the second stirring blade 120 is provided corresponding to the feed port 111; a butt joint is fixedly provided on the middle part of the top surface of the support plate, and a pin hole is provided on the butt joint for connecting with the end of the drive shaft to facilitate disassembly and assembly;

[0021] The above-mentioned mixing impeller for paint processing adopts a two-group stirring blade structure of a first stirring blade and a second stirring blade, which can increase the contact area with the material, thereby effectively stirring the material; wherein, the first stirring blade is provided with a feeding port, and one side of the second stirring blade is provided corresponding to the feeding port. The feeding port provides a position for the material to pass through, limits the movement of part of the material, and then the second stirring blade is used to cut and stir this part of the material. The overall coordination can accelerate the flow and mixing of the material, thereby strengthening the vortex effect formed, and further enhancing the overall stirring and mixing quality.

[0022] Furthermore, the first stirring blade 110 is tilted away from the axis of the support plate 100, and the inclined surface provides a force-releasing effect, thereby reducing the rotational stirring resistance, so that the entire blade 110 can rotate at a high speed and effectively stir the material.

[0023] Furthermore, the second stirring blade 120 is tilted away from the axis of the support plate 100; the tilting direction of the second stirring blade 120 is opposite to the tilting direction of the first stirring blade 110, and the higher tilted side of the second stirring blade 120 corresponds to the position of the feed port 111; the second stirring blade is also an inclined structure, which can also reduce the rotational stirring resistance, and its tilting direction is different from that of the first stirring blade, which can further stir the material and improve the mixing effect; and the second stirring blade is set corresponding to the feed port, and the material passing through the feed port will be cut and broken up by the second stirring blade, thereby accelerating the mixing of the material, and is also conducive to the formation of vortexes, thereby improving the overall mixing quality.

[0024] Furthermore, the lower inclined side of the second stirring blade 120 is located in the middle position of the two adjacent first stirring blades 110; the higher inclined side is close to the upstream position in the rotation direction; this structural design makes the second stirring blade closer to the side of the material passing through ...

[0025] Furthermore, the higher inclined side of the second stirring blade 120 is higher than the middle of the feeding port 111 and lower than the top of the feeding port; since the higher inclined end of the first stirring blade is closer to the second stirring blade on the downstream side, part of the material moving along the inclined surface of the first stirring blade will fall back from above the second stirring blade. The higher inclined end of the second stirring blade is in this position, which can stir the material above and passing through the feeding port, thereby effectively enhancing the overall mixing effect.

[0026] Furthermore, an outwardly flared column 121 is provided on the lower inclined side of the second stirring blade 120, and the connection between the column and the second stirring blade is smoothly rounded. The column design can change the direction or stir the material moving along the wall of the second stirring blade to a certain extent. During high-speed rotation, it forms a transverse V-shaped cutting effect on the material, so that the material is better mixed. In addition, the column design can strengthen the structural strength of the second stirring blade to prevent easy breakage and damage.

[0027] Furthermore, a plurality of insertion holes are provided on the side wall of the support plate, and the insertion holes are distributed in a circular array around the axis of the support plate; an insertion rod is fixedly provided on the wall surface of the column bar close to the support plate, and the shape of the insertion rod is adapted to the shape of the insertion hole; the insertion rod is inserted into the insertion hole, and the wall surface of the second stirring blade is arranged close to the outer wall of the support plate and fixedly connected by welding; the provided insertion rod and insertion hole can facilitate the alignment installation of the second stirring blade, and it is easy to arrange it to the required installation position.

[0028] Furthermore, one side of the feed port 111 extends through the end of the first stirring blade 110, and pressure plates 112 are fixed on both sides of the end of the feed port 111. The spacing between the two pressure plates 112 is adapted to the thickness of the support plate 100, and the two pressure plates are fixedly connected to the upper and lower wall surfaces of the edge of the support plate; wherein, the top and bottom edges of the support plate are provided with a plurality of snap positions for adapting and placing the pressure plates for alignment installation, so as to facilitate the arrangement of multiple second stirring blades to the desired positions; the fixed connection method includes but is not limited to bolt connection and welding fixation, preferably welding fixation, to provide a stable connection and prevent loosening problems.

[0029] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application are also within the scope of protection of the present invention.
