The quality of the road marking paint directly affects important indicators such as the durability, visibility, and anti-skid performance of the markings.
[0003] In the production process of traditional road marking paint, the raw materials often need to be finely ground to achieve a suitable particle size distribution, thereby ensuring the various properties of the paint.
[0004] For example, Chinese utility model patent with announcement number CN221471938U provides a grinding device for the production of road marking paint. This device controls the rotation of the first grinding roller and the second grinding roller on the screen to perform secondary grinding of the raw material, and filters the raw material through the screen, thereby improving grinding efficiency and grinding quality, and avoiding the situation where the grinding effect is affected by the change of grinding gap.
[0005] However, existing grinding devices, which grind the paint on a filter screen, are prone to clogging and loss of filtration function, and can also damage the filter screen, reducing its filtration efficiency. Therefore, a marking paint grinding device is proposed to solve the above-mentioned technical problems. Utility Model Content
[0006] In view of the shortcomings of the existing technology, this utility model proposes a road marking paint grinding device to solve the technical problems mentioned in the background art, that the existing grinding devices, by grinding on the filter screen, are prone to causing the filter screen to become clogged and lose its filtering function, and are also prone to damaging the filter screen and reducing its filtering effect.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a marking paint grinding device, comprising:
[0008] A shielding shell, wherein a receiving shell is provided at the bottom of the shielding shell, and an annular filter screen is provided on the receiving shell;
[0009] A grinding mechanism is disposed within the shielding housing. The grinding mechanism includes a receiving plate fixedly disposed within the shielding housing and a rotatable grinding wheel, as well as a drive assembly for driving the grinding wheel to rotate.
[0010] A guiding component, disposed on the grinding wheel, converts the rotation of the grinding wheel into guiding powder into the filter screen.
[0011] In a preferred embodiment, the shielding shell is further provided with a feeding hopper that extends into the grinding wheel, and the bottom of the receiving shell is provided with a discharge port that communicates with the inner side of the filter screen.
[0012] In a preferred embodiment, the guiding component includes:
[0013] The connecting frame is fixedly mounted on the grinding wheel;
[0014] A guide scraper is disposed on the connecting frame. The bottom surface of the guide scraper abuts against the receiving shell, and one end of the guide scraper abuts against the filter screen. The angle between the side of the guide scraper facing its direction of movement and the tangent of the filter screen is less than 90°.
[0015] In a preferred embodiment, the grinding wheel is further provided with a dredging component, which converts the rotation of the grinding wheel into dredging of the filter screen.
[0016] In a preferred embodiment, the unblocking component includes:
[0017] The connecting frame is fixedly mounted on the grinding wheel;
[0018] A screening grid is disposed at the end of the connecting frame, and its bottom surface abuts against the receiving shell. The receiving shell has a communicating slag discharge trough. The angle between the side of the screening grid facing its direction of movement and the tangent of the filter screen is greater than 90°.
[0019] The connecting rod is hinged at one end to the screening grid and has a brush at the other end, which is attached to the filter screen.
[0020] In a preferred embodiment, the connecting rod is connected to the screening grid by a tension spring, the outer circumferential surface of the filter screen is arranged with multiple sets of protrusions, and the connecting rod is provided with a guide post, which abuts against the protrusions.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] In use, the marking paint to be ground is added to the grinding mechanism. The drive component controls the grinding wheel to rotate on the receiving wheel, grinding the marking paint. The ground material falls into the receiving shell, and during the rotation of the grinding wheel, a guide component directs the material from the receiving shell into the inner side of the annular filter screen.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.
[0030] Example:
[0031] like Figure 1 , 2 As shown, this utility model provides a marking paint grinding device, including a shielding shell 1, a receiving shell 3 at the bottom of the shielding shell 1, an annular filter screen 7 on the receiving shell 3, a grinding mechanism inside the shielding shell 1, the grinding mechanism including a receiving plate 15 fixedly installed inside the shielding shell 1 and a rotatable grinding wheel 6, and a driving component for driving the grinding wheel 6 to rotate, a feeding hopper 2 on the shielding shell 1, the feeding hopper 2 extending into the grinding wheel 6, and a discharge port 5 at the bottom of the receiving shell 3, the discharge port 5 communicating with the inner side of the filter screen 7.
[0032] In use, the raw material for the road marking paint to be ground is fed into the grinding wheel 6 through the feed hopper 2. The grinding wheel 6 is rotated by the drive component to grind the raw material. It can be understood that the drive component can be directly driven by a motor or other drive methods. The ground powder falls onto the receiving shell 3 through the gap between the grinding wheel 6 and the receiving plate 15, and is then filtered through the filter screen 7 and discharged from the device through the discharge port 5.
[0033] like Figure 2 , 3 As shown, in this embodiment, a guiding component is provided on the grinding wheel 6, which converts the rotation of the grinding wheel 6 into guiding the powder into the filter screen 7. The guiding component includes a connecting frame 9 fixedly mounted on the grinding wheel 6, and a guiding scraper 10 is provided on the connecting frame 9. The bottom surface of the guiding scraper 10 abuts against the receiving shell 3, and one end of it abuts against the filter screen 7.
[0034] As the grinding wheel 6 rotates, the guide scraper 10 moves on the receiving shell 3 to scrape the powder on the receiving shell 3. And because the angle between the side of the guide scraper 10 facing its direction of movement and the tangent of the filter screen 7 is less than 90°, the powder can move along the guide scraper 10 to the filter screen 7 and be filtered by the filter screen 7.
[0035] like Figure 2 , 3 As shown, in this embodiment, the grinding wheel 6 is also equipped with a clearing component, which converts the rotation of the grinding wheel 6 into clearing of the filter screen 7. The clearing component includes a connecting frame 9 fixedly mounted on the grinding wheel 6. A screening grid 11 is provided at the end of the connecting frame 9. The bottom surface of the screening grid 11 abuts against the receiving shell 3. A slag discharge groove 4 is provided on the receiving shell 3. One end of the connecting rod 12 is hinged to the screening grid 11, and the other end is provided with a brush 13, which is attached to the filter screen 7.
[0036] During the rotation of the grinding wheel 6, the brush 13 moves on one side of the filter screen 7 to clean the filter screen 7 and prevent it from becoming clogged. The brush 13 can also separate the particles that do not meet the size requirements on the receiving shell 3 and the outside of the filter screen 7 through the screening grid 11. Since the angle between the side of the screening grid 11 facing its direction of movement and the tangent of the filter screen 7 is greater than 90°, it can move the insufficiently ground raw materials to the end of the screening grid 11 away from the filter screen 7, until they are discharged through the slag discharge trough 4.
[0037] like Figure 2 , 3As shown, in this embodiment, the connecting rod 12 is connected to the screening grid 11 by a tension spring 14. Multiple sets of protrusions 8 are arranged circumferentially on the outer surface of the filter screen 7. A guide post 16 is provided on the connecting rod 12, and the guide post 16 abuts against the protrusions 8. During its movement, the brush 13 remains in contact with the filter screen 7 under the action of the tension spring 14. The cooperation between the protrusions 8 and the guide post 16 causes the brush 13 to swing back and forth on one side of the filter screen 7, extending the bristles into the filter screen 7 to clear blockages, thereby improving the clearing efficiency of the filter screen 7.
[0038] The specific usage and beneficial effects of this utility model are as follows:
[0039] In use, the marking paint to be ground is added to the grinding mechanism. The grinding wheel 6 is controlled by the drive component to rotate on the receiving wheel to grind the marking paint. The ground material falls into the receiving shell 3, and during the rotation of the grinding wheel 6, the guide component guides the material on the receiving shell 3 into the inner side of the annular filter screen 7. This effectively prevents direct grinding on the filter screen 7, which would cause clogging and reduced grinding efficiency. It also prevents damage to the filter screen 7, reducing the frequency of device maintenance. Furthermore, the vibrating brush 13 automatically unclogs the filter screen 7, improving the filtration effect of the ground material.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
