DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0022] As Figures 1-4 shown, an embodiment of the utility model provides a mixing and stirring device for processing paint, including:

[0023] Mixing cylinder 1, a drain pipe 3 is installed through the lower end on one side of the mixing cylinder 1, and a valve is installed in the drain pipe 3, which can stably support the mixing cylinder 1; among them, a hinge is installed at the upper end of the outer wall of the mixing cylinder 1, and a cover plate 4 is installed on the hinge. When mixing and stirring, the cover plate 4 can be covered to prevent liquid from splashing out. A drain pipe 3 is installed through the lower end on one side of the mixing cylinder 1, and a valve is installed in the drain pipe 3 to discharge the mixed liquid;

[0024] Mixing and stirring assembly; the mixing and stirring assembly includes a short pipe 13 that penetrates the bottom of the mixing cylinder 1 and is rotatably arranged. The upper end of the short pipe 13 is fixedly connected to a connecting plate 6 that slidably abuts against the inner bottom of the mixing cylinder 1. In this way, when the connecting plate 6 rotates, it can scrape the inner bottom of the mixing cylinder 1 to prevent sediment accumulation; a plurality of stirring plates 8 with different inclination angles are fixed at the upper end of the connecting plate 6, and a plurality of diversion holes 9 are provided through the stirring plates 8. Since the inclination angles of the stirring plates 8 are different, the directions of the diversion holes 9 are also different. When the liquid flows through the diversion holes 9, the flow direction of the liquid can be changed under the action of the diversion holes 9, so that the paint can be better mixed; a vertical rod 5 is rotatably installed in the short pipe 13, the vertical rod 5 penetrates the connecting plate 6 and is rotatably connected to it, and a plurality of stirring rods 7 are fixed on the vertical rod 5;

[0025] A driving mechanism for driving the vertical rod 5 and the short pipe 13 to rotate is installed at the bottom of the mixing cylinder 1. The driving mechanism includes an installation box 10 fixed at the bottom of the mixing cylinder 1. A motor 12 is installed in the installation box 10. The output end of the motor 12 is fixedly connected with a first bevel gear 14. Second bevel gears 15 are fixed on both the vertical rod 5 and the short pipe 13. The first bevel gear 14 meshes with the two second bevel gears 15. A vertical plate 11 is installed in the installation box 10, and the motor 12 is installed on the vertical plate 11.

[0026] The detailed working process of the present utility model is as follows:

[0027] 1. Open the cover plate 4, add raw materials into the mixing cylinder 1, then cover the cover plate 4 and start the motor 12;

[0028] 2. The motor 12 works to drive the first bevel gear 14 and the two second bevel gears 15 to rotate. The two second bevel gears 15 rotate in opposite directions, so as to realize that the rotation directions of the short pipe 13 and the vertical rod 5 are opposite. The rotation of the short pipe 13 drives the connecting plate 6 and the stirring plates 8 to rotate. Since the angles of the stirring plates 8 are different, the disturbance of the liquid during their rotation is different and the liquid passes through the diversion holes 9 in different directions, and its flow direction also changes, so that the liquid paint can be more effectively and efficiently mixed; since the connecting plate 6 slidably abuts against the inner bottom of the mixing cylinder 1, the rotation of the connecting plate 6 can scrape the inner bottom of the mixing cylinder 1 to prevent sediment accumulation;

[0029] 3. Meanwhile, the rotation of the vertical rod 5 drives the rotation of the stirring rod 7, and the rotation direction of the stirring rod 7 is opposite to that of the connecting plate 6 and the stirring plate 8. Therefore, the liquid can be further disturbed in different directions, which can further improve the efficiency and effect of mixing the liquid paint.

[0030] 4. After the mixing is completed, the valve can be opened to discharge the mixed liquid through the drain pipe 3.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
