Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] See attached document Figures 1-4 The present invention provides a dual-axis variable-speed coating mixing and dispersing device, comprising a mixing tank 100 and a dispersing tank 200. The mixing tank 100 is positioned above the dispersing tank 200. A feed pipe is provided at the top of the outer wall of the mixing tank 100, and a coating discharge pipe is provided at the bottom of the outer wall of the dispersing tank 200. Support rods 310 are fixed at the bottom edge of the outer wall of the mixing tank 100, and the bottom ends of the support rods 310 are fixedly connected to the corresponding positions at the top of the outer wall of the dispersing tank 200. Fixed connecting frames 300 are fixed on both sides of the outer wall of the mixing tank 100, and the bottom ends of the fixed connecting frames 300 are fixedly connected to the corresponding positions on both sides of the outer wall of the dispersing tank 200. The bottom discharge end of the mixing tank 100 and the top feed end of the dispersing tank 200 are connected by a discharge pipe 320. The support rods 310 and the discharge pipe 320 can cooperate to connect and fix the mixing tank 100 and the dispersing tank 200, and can also fix the mixing tank 100 above the top of the outer wall of the dispersing tank 200.

[0024] The mixing tank 100 is equipped with a mixing and stirring component for mixing the coating. The mixing and stirring component includes a mixing and stirring rod 110. The upper and lower ends of the mixing and stirring rod 110 are rotatably connected to the upper and lower sides of the inner wall of the mixing tank 100 through bearing seats. The outer side of the mixing and stirring rod 110 is fixed with mixing and stirring blades 120 for stirring. The mixing and stirring rod 110 can stir the coating added to the mixing tank 100 through the mixing and stirring blades 120 when it rotates, so that the coating can be fully mixed and the quality of the coating after production can be improved.

[0025] The dispersion tank 200 is equipped with a coating dispersion component, which includes a dispersion stirring rod 210. The upper and lower ends of the dispersion stirring rod 210 are rotatably connected to the upper and lower sides of the inner wall of the dispersion tank 200 via bearing seats. Dispersion discs 220 for coating dispersion are provided on the outer wall side of the dispersion stirring rod 210 and inside the dispersion tank 200. The convex surface of the upper dispersion disc 220 faces upward, and the concave surface of the lower dispersion disc 220 faces upward. The outer wall side edges of both sets of dispersion discs 220 are also serrated. Simultaneously, the two sets of dispersion discs... The dispersion disc 220 is designed in this way so that the upper dispersion disc 220 can press the paint downward when rotating, while the lower dispersion disc 220 can feed the paint upward. This improves the dispersion effect of the two sets of dispersion discs 220 on the paint when rotating. The top of the outer wall of the dispersion disc 220 is fixed with dispersion teeth 230. Multiple dispersion teeth 230 are evenly arranged on the top of the outer wall of the dispersion disc 220 in a ring array. The dispersion teeth 230 are designed to cooperate with the rotation of the dispersion disc 220 to disperse the paint.

[0026] The mixing and stirring component and the coating dispersion component are connected by a speed-changing transmission mechanism. This mechanism includes a drive shaft 410, whose upper and lower ends are rotatably connected to the outer walls of the mixing tank 100 and the dispersion tank 200 respectively via bearing seats. The outer wall of the drive shaft 410 is connected to the mixing rod 110 and the dispersion rod 210 via a transmission gear set 420. In the transmission gear set 420, the diameter of the gear connected to the mixing rod 110 is larger than the diameter of the gear mounted on and meshing with it, while the diameter of the gear connected to the dispersion rod 210 is smaller than the diameter of the gear mounted on and meshing with it. This design ensures that the rotational speed of the mixing rod 110 is less than that of the dispersion rod 210. The rotational speed of the dispersing stirring rod 210 is increased, which can effectively improve the dispersion effect of the coating. A drive motor 400 is provided on one side of the outer wall of the dispersion tank 200 and at a position corresponding to the drive shaft 410. The output end of the drive motor 400 is connected to the outer wall of the drive shaft 410 through a synchronous belt pulley mechanism 430. The synchronous belt pulley mechanism 430 includes two synchronous pulleys and a connected synchronous belt. The two synchronous pulleys are respectively installed on the output end of the drive motor 400 and the drive shaft 410. The drive motor 400 is fixed to the left side of the fixed connecting bracket 300 through a bracket, so that the drive motor 400 can be fixed on the left side of the outer wall of the mixing tank 100 and the dispersion tank 200.

[0027] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. The control programs of all electrical equipment are edited by the production personnel in advance before production. This utility model does not make any technical improvements here, but only assumes that it can normally meet the needs of personnel.

[0028] First, personnel can add the raw materials of the coating into the mixing tank 100 through the feeding pipe at the top of the mixing tank 100. Then, the electric drive motor 400 drives the transmission shaft 410 to rotate, so that the transmission shaft 410 drives the mixing rod 110 to rotate through the upper transmission gear set 420. The rotating mixing rod 110 can mix and stir the added coating raw materials through the mixing blade 120. After the coating is mixed, personnel can open the valve on the discharge pipe 320 so that the coating raw materials can be discharged into the dispersion tank 200 through the discharge pipe 320 for subsequent dispersion steps. After the coating is discharged, personnel can add new coating raw materials into the mixing tank 100 to continue mixing.

[0029] When the 510 is rotated, the transmission gear set 420 at the bottom position can drive the dispersing and stirring rod 210 to rotate, so that the dispersing and stirring rod 210 can rotate and disperse the paint added to the dispersing tank 200 through the dispersing plate 220. After the paint is dispersed, it can be discharged by personnel.

[0030] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
