It should be noted that the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] An emulsifying device for the production of polyurethane coatings for furniture, as Figures 1 - 4As shown in the figure, it includes an emulsifying tank 1, a mounting cross beam 21, a servo motor 3, a rotating shaft 22, a first bevel gear 23, a shaft rod 24, a stirring plate 25 and a second bevel gear 26. The upper left side of the emulsifying tank 1 is provided with a feed pipe with an in-built control valve. Inside the emulsifying tank 1, there are two vertically opposite mounting cross beams 21. Between the middles of the two mounting cross beams 21, there is a rotating shaft 22 driven by a servo motor 3. The servo motor 3 is installed on the upper part of the emulsifying tank 1. On the lower sides of the middles of the two mounting cross beams 21, there are first bevel gears 23 connected through mounting brackets and surrounding the rotating shaft 22 with the rotating shaft 22 as the center. On the rotating shaft 22, there are two shaft rods 24 both perpendicular to the rotating shaft 22. On the shaft rods 24, there are stirring plates 25 for stirring the polyurethane coating to emulsify it. By controlling the servo motor 3 to drive the rotating shaft 22 to rotate, the rotating shaft 22 will drive the shaft rods 24 to revolve, and the shaft rods 24 will drive the stirring plates 25 to revolve. In this way, the coating in the emulsifying tank 1 is circumferentially rotated and stirred by the revolving shaft rods 24 and stirring plates 25. On one side of the stirring plate 25, there is a second bevel gear 26 meshing with the first bevel gear 23 and surrounding the shaft rod 24. The revolution of the stirring plate 25 will also drive the second bevel gear 26 to revolve and mesh with the first bevel gear 23. The second bevel gear 26 will drive the revolving stirring plate 25 to rotate automatically under the meshing action of the first bevel gear 23. In this way, on the basis of revolving and stirring, the emulsifying tank 1 is automatically and synchronously stirred up and down, and only through the drive of the servo motor 3 and the transmission of the first bevel gear 23 and the second bevel gear 26 can the operations of revolving and stirring and up and down stirring be completed. The structure is simple, and the automation and synchronism are high.

[0023] As Figure 3 shown in the figure, it further includes a stirring frame 27. On the shaft rod 24, there is a stirring frame 27 surrounding the stirring plate 25. The stirring frame 27 is parallel to the emulsifying tank 1 and perpendicular to the rotating shaft 22. The rotation of the rotating shaft 22 will drive the stirring frame 27 to revolve around the stirring plate 25 through the shaft rod 24. In this way, on the basis of the revolution and rotation of the stirring plate 25, the stirring area is increased through the stirring frame 27, and the emulsifying efficiency is improved.

[0024] As Figure 4 shown in the figure, it further includes stirring rods 41. On the lower part of the stirring frame 27, on the side close to the inner wall of the emulsifying tank 1, there are a plurality of uniformly spaced stirring rods 41. The revolution of the stirring frame 27 will drive the stirring rods 41 to revolve, and the stirring rods 41 are suitable for stirring the coating in the emulsifying tank 1.

[0025] As Figures 3 - 5As shown in the figure, it further includes a wedge block 42. The stirring rod 41 is made of an elastic material. A circle of wedge blocks 42 is connected to the inner wall of the emulsifying tank 1. The stirring rod 41 is adapted to be in contact and cooperation with the wedge block 42. During the rotation of the stirring rod 41, the stirring rod 41 will collide with the wedge block 42. Under the elastic action of the stirring rod 41, the stirring rod 41 will be forced to cross over the wedge block 42 and generate vibrations, thereby further mixing the paint in the emulsifying tank 1 and fully emulsifying the paint.

[0026] As Figure 6 shown in the figure, it further includes a discharge pipe and a spiral blade 5. The lower part of the emulsifying tank 1 is in an inverted conical shape, which is convenient for the discharge of the emulsified paint. The emulsifying tank 1 is provided with a discharge pipe with an internal valve at the lower end. The lower end of the rotating shaft 22 extends above the inner bottom of the emulsifying tank 1. A spiral blade 5 is connected to the lower end of the rotating shaft 22. The spiral blade 5 corresponds to the upper part of the discharge pipe on the emulsifying tank 1. If it is necessary to discharge the emulsified paint, the valve in the discharge pipe on the emulsifying tank 1 is opened, and the rotating shaft 22 is rotated. The rotating shaft 22 will drive the spiral blade 5 to rotate. The spiral blade 5 will accelerate the flow rate of the paint in the emulsifying tank 1 and make the paint quickly discharged downward.

[0027] As Figure 6 shown in the figure, it further includes a tank end cover 11. The emulsifying tank 1 has a detachable tank end cover 11. The tank end cover 11 is installed at the upper end of the emulsifying tank 1. The servo motor 3 is installed on the tank end cover 11. A rhombic rod that is slidably matched with the rotating shaft 22 is connected to the output shaft of the servo motor 3. The servo motor 3 drives the rotating shaft 22 through the rhombic rod. By removing the tank end cover 11 and the servo motor 3, it is convenient to clean the inner wall of the emulsifying tank 1, and at the same time, it is also convenient to perform maintenance and replacement operations.
