[0002] Paint is applied to the surface of an object to be protected or decorated, forming a thin, continuous film that adheres firmly to the surface. It is typically a viscous liquid composed primarily of resin, oil, or emulsion, with or without pigments and fillers, and additives, and is prepared using organic solvents or water. Some paints require grinding larger bulk materials into powder during production.

[0003] The current paint grinder can only grind the paint once when grinding the paint, and cannot grind the paint in a cycle, so that the paint is not ground thoroughly, which affects the spraying effect of the paint in later use. Therefore, it is necessary to design a paint circulation grinder. Summary of the Invention

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-5 The utility model provides a paint circulation grinder, which includes a support base 1, a turning mechanism 2 is provided at the side end of the support base 1, and a grinding barrel 3 is provided inside the support base 1. The support base 1 is connected to the grinding barrel 3 through the turning mechanism 2. The upper end of the grinding barrel 3 is fixedly connected to the end cover 4, and the upper end surface of the end cover 4 is provided with a feeding port 401. The feeding port 401 is internally threadedly connected to the first sealing cover 6, the upper end of the end cover 4 is fixedly connected to the second motor 5, and the output end of the second motor 5 is fixedly connected to the rotating shaft 12, and the rotating shaft 12 is rotatably connected to the end cover 4. The lower end circumferential surface of the rotating shaft 12 is fixedly connected to the dynamic grinding disc 16; the inner wall of the grinding barrel 3 is fixedly connected to the connecting rod 14, and the end of the connecting rod 14 away from the grinding barrel 3 is fixedly connected to the static grinding disc 15. The static grinding disc 15 is provided with two, and is distributed at the upper and lower ends of the dynamic grinding disc 16; the lower end of the grinding barrel 3 is fixedly connected to the discharge pipe 8, and the circumferential surface of the lower end of the discharge pipe 8 is threadedly connected to the second sealing cover 7.

[0027] Specifically, the paint to be ground is added to the inside of the grinding barrel 3 through the feeding port 401, so that the paint accumulates on the upper end of the dynamic grinding disc 16. After the paint is added, the feeding port 401 is sealed with the first sealing cover 6, and then the second motor 5 is started. At this time, the dynamic grinding disc 16 can be driven to rotate with the cooperation of the rotating shaft 12, and then the paint can be ground with the cooperation of the upper static grinding disc 15. During the grinding process, the ground paint will be thrown out under the action of the centrifugal force of the dynamic grinding disc 16, and then fall along the inner wall of the grinding barrel 3 and fall to the lower end of the grinding barrel 3. After that, the turning mechanism 2 can drive the grinding barrel 3 to turn 180 degrees, so that the ground paint at the lower end is located at the upper end. Since the gap between the static grinding disc 15 and the dynamic grinding disc 16 at the lower end is smaller, the paint at the lower end can be ground with the cooperation of the static grinding disc 15 and the dynamic grinding disc 16 at the lower end, thereby realizing the cyclic grinding of the paint, making the paint grinding more fine, which is beneficial to improving the later spraying effect; after the paint has circulated back and forth many times, the second sealing cover 7 is opened at this time, so that the ground paint is discharged outward through the discharge pipe 8, which is convenient for later use.

[0028] Specifically, if Figure 2 and Figure 4 As shown, the turning mechanism 2 includes a fixed plate 201, a bearing seat 202, a worm 203, a worm gear 204, a connecting shaft 205 and a first motor 206. The left side of the support seat 1 is fixedly connected to the fixed plate 201, and the upper end of the fixed plate 201 is fixedly connected to the bearing seat 202 and the first motor 206. The worm 203 is rotatably connected inside the bearing seat 202, and the worm 203 is fixedly connected to the output end of the first motor 206; the connecting shaft 205 is rotatably connected inside both sides of the support seat 1, and the connecting shaft 205 is fixedly connected to the grinding barrel 3. The left end of the connecting shaft 205 located on the left side is fixedly connected to the worm gear 204, and the worm gear 204 meshes with the worm 203. When working, the first motor 206 works. At this time, the connecting shaft 205 can be driven to rotate with the cooperation of the worm 203 and the worm gear 204. As the connecting shaft 205 rotates, it is convenient to drive the grinding barrel 3 to rotate, thereby facilitating the grinding barrel 3 to flip 180 degrees, which is beneficial for the grinding barrel 3 to cycle and perform grinding operations.

[0029] like Figure 4 As shown, the lower end of the fixed plate 201 is fixedly connected to a reinforcing plate 11, and the reinforcing plate 11 is fixedly connected to the support seat 1. During operation, by setting the reinforcing plate 11, the stability of the connection between the fixed plate 201 and the support seat 1 can be improved under the action of the reinforcing plate 11.

[0030] like Figure 2As shown, a limiting groove 9 is provided on the inner side of the support seat 1, and the limiting groove 9 is semicircular. The limiting groove 9 is slidably connected to the limiting rod 10, and the limiting rod 10 is fixedly connected to the grinding barrel 3. During operation, by setting the limiting groove 9 and the limiting rod 10, when the grinding barrel 3 flips, the limiting rod 10 will be driven to slide inside the limiting groove 9, thereby limiting the grinding barrel 3 and effectively preventing the grinding barrel 3 from flipping excessively.

[0031] like Figure 5 As shown, a crushing rod 17 is fixedly connected to the circumferential surface of the rotating shaft 12. There are multiple crushing rods 17, which are distributed in a circular array. When working, the paint can be crushed under the action of the crushing rods 17 by setting the crushing rods 17, so that the crushed paint is conducive to the grinding operation.

[0032] like Figure 5 As shown, a guide ring 13 is fixedly connected to the inner wall of the grinding barrel 3. Two guide rings 13 are provided and are distributed at the upper and lower ends of the dynamic grinding disc 16. The end face shape of the guide ring 13 is V-shaped. When working, by setting the guide ring 13, under the action of the guide ring 13, the paint is easily gathered together.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
