Detailed Implementation

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] Example 1:

[0052] like Figures 1 to 6 As shown, this utility model provides a paint mixing device, including: a mixing bin 1 and a feeding structure arranged on the mixing bin 1 for feeding paint into the mixing bin 1.

[0053] The feeding structure includes a movable frame 2 rotatably mounted on the mixing bin 1, several paint boxes 201 evenly arranged on the movable frame 2 and connected to the mixing bin 1, an annular support frame 202 fixedly mounted on the mixing bin 1, the movable frame 2 movably installed inside the annular support frame 202, a rotating component arranged on the movable frame 2 for controlling the rotation of the movable frame 2, and a feeding component arranged inside the paint box 201 for controlling the falling of the paint in the paint box 201. In use, an appropriate amount of paint is poured into the corresponding paint box 201, and the paint can fall into the mixing bin 1 through the outlet of the paint box 201.

[0054] Specifically, the rotating component includes a motor 203 arranged on one side of the annular support frame 202, a linkage gear 204 arranged on the output end of the motor 203, and a linkage gear ring 205 fixedly sleeved on the movable frame 2. The linkage gear ring 205 meshes with the linkage gear 204. When the motor 203 is turned on, it drives the linkage gear 204 to rotate. When the linkage gear 204 rotates, it can drive the movable frame 2 to rotate slowly through meshing with the linkage gear ring 205. The rotating movable frame 2 can drive the paint box 201 above to move in a circular motion, so that the paint can be evenly sprinkled into the mixing bin 1.

[0055] Specifically, the rotating assembly also includes several pulleys 206 that are uniformly rotated and installed on the movable frame 2, and a guide groove 207 opened inside the annular support frame 202. The pulleys 206 are movably installed in the guide groove 207. The rotating movable frame 2 can drive the pulleys 206 to roll in the guide groove 207. The arrangement of the pulleys 206 and the guide groove 207 can make the movable frame 2 rotate more smoothly.

[0056] Specifically, the material feeding assembly includes a connecting shaft 208 rotatably installed inside the paint tank 201, several material feeding plates 209 evenly arranged on the connecting shaft 208 and in contact with the inner wall of the paint tank 201, a bevel gear 210 arranged at one end of the connecting shaft 208, and a bevel ring 211 arranged on the annular support frame 202 and meshing with the bevel gear 210. When the paint tank 201 moves in a circular motion, it can drive the bevel gear 210 to move in a circular motion through the connecting shaft 208. The bevel gear 210 rotates by meshing with the bevel ring 211, which in turn drives the material feeding plates 209 to rotate and feed the paint through the connecting shaft 208, causing the paint to fall evenly from the paint tank 201.

[0057] The material feeding structure also includes a transparent window 212 arranged inside the paint tank 201, through which the amount of paint in the paint tank 201 can be observed.

[0058] Example 2:

[0059] Based on Example 1, in order to mix the paint material fed into the mixing bin 1, a mixing structure for agitating the paint material in the mixing bin 1 is arranged on the feeding structure.

[0060] The mixing structure includes a connecting plate 3 arranged at one end of the paint tank 201 and rotatably installed inside the mixing chamber 1, several discharge holes 301 evenly opened inside the connecting plate 3, the discharge holes 301 being connected to the discharge port of the paint tank 201, and several mixing rods 302 evenly rotatably installed inside the connecting plate 3. The circular motion of the paint tank 201 can drive the connecting plate 3 to rotate inside the mixing chamber 1, so that the connecting plate 3 drives the mixing rods 302 to move in a circular motion inside the mixing chamber 1 and agitate the paint, for mixing the paint.

[0061] Example 3:

[0062] Based on Example 2, in order to further improve the stirring effect of the stirring rod 302, a linkage structure for controlling the rotation of the stirring structure is arranged on the stirring structure.

[0063] The linkage structure includes a driven gear 4 arranged at one end of the stirring rod 302 and a fixed gear ring 401 arranged on the inner wall of the stirring bin 1 and meshing with the driven gear 4. When the stirring rod 302 moves in a circular motion, it can drive the driven gear 4 to move accordingly, so that the driven gear 4 drives the stirring rod 302 to rotate through meshing with the fixed gear ring 401, thereby improving the stirring effect.

[0064] Working principle: When in use, pour an appropriate amount of paint or raw material into the corresponding paint tank 201. The amount of paint in the paint tank 201 can be observed through the transparent window 212. Then, turn on the motor 203 to drive the linkage gear 204 to rotate. When the linkage gear 204 rotates, it meshes with the linkage gear ring 205, causing the movable frame 2 to rotate slowly. The rotating movable frame 2 causes the paint tank 201 above to rotate, so that the paint tank 201 can drive the bevel gear 210 to rotate via the connecting shaft 208. When the bevel gear 210 rotates, it rotates by meshing with the bevel gear ring 211, thereby driving the connecting shaft 208 and the material-dispensing plate 209 to rotate. The continuous rotation of the material-dispensing plate 209 dispenses the paint, causing it to fall evenly from the paint tank 201. Finally, the paint flows into the mixing bin 1 through the discharge hole 301. During the circular motion of the paint box 201, the paint is evenly sprinkled into the mixing bin 1, which promotes the uniform distribution of the paint in the mixing bin 1. At the same time, the circular motion of the paint box 201 can drive the connecting plate 3 to rotate in the mixing bin 1, so that the connecting plate 3 drives the mixing rod 302 to move in a circular motion in the mixing bin 1 and stir the paint, which is used for mixing the paint. At the same time, the mixing rod 302 can drive the driven gear 4 to move along with it, so that the driven gear 4 can rotate by meshing with the fixed gear ring 401, which in turn can drive the mixing rod 302 to rotate. This allows the mixing rod 302 to rotate while moving in a circular motion, with two motion modes, which improves the mixing effect.

[0065] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
