[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following.

[0023] Embodiment 1

[0024] As Figures 1 to 3As shown in the figure, a two-color roller includes a cylinder body 1 and a partition leaf 3. The partition leaf 3 is arranged inside the cylinder body 1 to divide the interior of the cylinder body 1 into two chambers 9. The partition leaf 3 is of a spiral structure. A number of penetration holes 2 are evenly formed on the side wall of the cylinder body 1. Side plates 8 are arranged on both sides of the cylinder body 1. Two pigment inlets respectively communicating with the two chambers 9 are formed on one of the side plates 8. A sealing plug 7 is arranged on the side plate 8 to seal the pigment inlets. A sponge 11 is arranged outside the cylinder body 1. The sponge 11 is adhered to the outside of the cylinder body 1 by glue. A grip 5 is further included. One end of the grip 5 is provided with a bracket 4. The bracket 4 is in a Y shape, and connecting rings 15 are arranged at the two ends of the bracket 4. Threaded connection holes are formed on the side plate 8. The side plate 8 is threadedly connected with a mounting buckle 6 through the threaded connection holes. The connecting ring 15 is rotatably connected with the mounting buckle 6. In this embodiment, a partition leaf 3 along the axial direction of the cylinder body 1 is arranged inside the cylinder body 1 to divide the space inside the cylinder body 1 into two chambers 9. The two chambers 9 are isolated from each other. During use, different-color pigments are respectively injected into the two chambers 9 through the two pigment inlets, and then the sealing plug 7 is inserted into the pigment inlets to seal the pigment inlets. Then, an operator holds the grip 5, so that the grip 5 drives the bracket 4 and the cylinder body 1 to move along the position where the warning line needs to be painted. At this time, the pigments inside the cylinder body 1 penetrate into the sponge 11 through the penetration holes 2, and then the warning line is painted at the position where the warning line needs to be painted through the sponge 11. Two colors can be directly painted, and the two colors are evenly distributed.

[0025] Furthermore, the partition leaf 3 extends to the outside of the cylinder body 1. In this embodiment, in order to make the two different-color pigments mix together when oozing from the penetration holes 2 into the sponge 11, the partition leaf 3 is extended out of the cylinder body 1 to separate the sponge 11, so that the two pigments cannot mix together, ensuring the quality of the warning line painting.

[0026] Embodiment Two

[0027] As Figures 1 to 4As shown in the figure, based on the first embodiment, a partition 10 is provided in the middle of the cylinder body 1 to divide the chamber 9 into a left chamber and a right chamber. The other side plate 8 is also provided with two pigment injection ports respectively communicating with the two chambers. In this embodiment, the partition 10 is coaxially arranged with the cylinder body 1. The partition 10 divides the chamber storing pigments of the same color into a left chamber and a right chamber, and two pigment injection ports are also provided on the other side plate 8. Since the cylinder body 1 will keep rolling during painting, and the spiral partition leaf 3 will cause uneven distribution of pigments in the cylinder body 1 when the cylinder body 1 rolls. This is because the spiral partition leaf 3 and the cylinder body 1 actually form a conveying structure similar to an auger, and when the cylinder body 1 rotates, the pigments in the cylinder body 1 will be conveyed in one direction, resulting in uneven distribution of pigments. By injecting pigments into the left chamber and the right chamber through the pigment injection ports on the two side plates 8, and setting a partition 10 in the middle, the conveying of pigments can be blocked, so that the pigments can be evenly distributed in the cylinder body 1.

[0028] Embodiment Three

[0029] As Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown in the figure, based on the second embodiment, a plurality of baffles 12 coaxially arranged with the cylinder body 1 are evenly arranged in the cylinder body 1. Liquid leakage holes 13 are provided on the baffles 12. A sealing column 14 is provided on the sealing plug 7. The sealing column 14 is inserted into the cylinder body 1 and extends into the liquid leakage holes 13 on the baffles 12 to seal the liquid leakage holes 13. In this embodiment, in order to enable the roller to paint a warning line on a vertical wall, by arranging a plurality of baffles 12 in the cylinder body 1, the left chamber and the right chamber are further divided into a plurality of liquid storage chambers. After the pigments are injected into the left chamber and the right chamber, the sealing column 14 is inserted to block the liquid leakage holes 13 on the baffles 12, so that the pigments can be stored in each liquid storage chamber. When painting on a vertical wall, the pigments in the liquid storage chambers seep out from the corresponding penetration holes 2, so as to ensure that pigments can overflow in each area along the axial direction of the cylinder body 1, so that painting can be carried out on a vertical wall. In order to ensure the painting quality, it can be reversed for use after being used for a period of time to ensure even painting.

[0030] The above is only the preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention. Therefore, any changes, modifications, equivalent changes and modifications made to the above embodiments according to the technical solution of the present invention without departing from the content of the technical solution of the present invention all fall within the protection scope of this technical solution.
