[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, a sanding mechanism for a paint-making sand mill includes a body 1. The body 1 includes a grinding cylinder 2, a drive assembly 3, and a grinding assembly 4. The drive assembly 3 is located on one side of the body 1, and its output end is connected to the grinding assembly 4. The grinding assembly 4 is installed inside the grinding cylinder 2. The grinding cylinder 2 has a feed inlet 5 at its top and a discharge outlet 6 at its bottom. The drive assembly 3 includes a drive motor 7 installed on the outside of the grinding cylinder 2 and a reducer 8 connected to the output end of the drive motor 7. The output end of the reducer 8 passes through the side wall of the grinding cylinder 2 and is connected to the grinding assembly 4. The grinding assembly 4 includes a rotating spindle 9 fixed to the output end of the reducer 8. At least two sets of grinding discs 10 are axially spaced on the rotating spindle 9. Each grinding disc 10 includes a grinding base 11 and a grinding head 12. Several sets of grinding heads 12 are provided, and each grinding head 12 is detachably installed on the outer ring of the grinding base 11. Grinding teeth 13 are fixedly provided on the surface of each grinding head 12.

[0024] Furthermore, a movable connecting component is provided between the grinding head 12 and the grinding base 11. The movable connecting component includes a connecting block 14 and a movable block 15. One end of the connecting block 14 is fixedly installed on the outside of the grinding base 11 by a threaded connection.

[0025] In this embodiment, the grinding head 12 can swing at a certain angle relative to the grinding base 11 through the movable connecting component. During the grinding process, when encountering paint particles of different shapes and sizes, the grinding head 12 can automatically adjust the angle according to the actual situation, thereby making better contact with the paint particles and improving the uniformity and efficiency of grinding.

[0026] Furthermore, the other end of the connecting block 14 is hinged to the movable block 15, and the other end of the movable block 15 is fixedly connected to the grinding head 12.

[0027] In this embodiment, the hinged connection between the connecting block 14 and the movable block 15 provides the grinding head with greater freedom of movement. When the paint grinding mill is running to grind paint, the grinding head can more flexibly change its angle to fully conform to paint particles of different shapes and sizes when faced with complex and diverse paint particles.

[0028] Furthermore, a cleaning mechanism is installed inside the grinding cylinder 2. The cleaning mechanism includes a booster water pump 16 and a cleaning water pipe 17. A hollow channel is opened inside the rotating spindle 9, and the cleaning water pipe 17 is installed inside the hollow channel.

[0029] In this embodiment, by setting a cleaning mechanism inside the grinding cylinder, after the paint grinding mill completes the paint grinding work, the booster water pump 16 can be started. The booster water pump 16 pressurizes the cleaning water and delivers it to the cleaning water pipe 17. The water in the cleaning water pipe 17 is delivered to each nozzle 18 through the hollow channel inside the rotating spindle 9. The nozzle 18 sprays water evenly on the inner wall of the grinding cylinder 2 to wash away the paint residue adhering to the inner wall of the grinding cylinder 2 and the grinding components 4. This effectively avoids the impact of paint residue on subsequent grinding work, while also reducing the labor intensity of manual cleaning and improving the cleaning efficiency and ease of use of the equipment.

[0030] Furthermore, one end of the cleaning water pipe 17 passes through the side wall of the grinding cylinder 2 and is connected to the booster water pump 16, which is fixedly installed on the outside of the grinding cylinder 2.

[0031] In this embodiment, this installation method ensures the stability of the connection between the cleaning water pipe 17 and the booster water pump 16. At the same time, installing the booster water pump 16 on the outside of the grinding cylinder 2 facilitates the daily maintenance and repair of the booster water pump 16. When the booster water pump 16 malfunctions, it can be repaired or replaced quickly and conveniently, reducing equipment downtime and ensuring the continuity of production.

[0032] Furthermore, a number of nozzles 18 are provided on the outside of the rotating spindle 9, and one end of the nozzle 18 is connected to the cleaning water pipe 17.

[0033] In this embodiment, several sets of nozzles 18 are evenly distributed on the outside of the rotating spindle 9, which can spray water onto the inner wall of the grinding cylinder 2 and the grinding assembly 4 from different angles and positions during the cleaning process, ensuring that there are no dead corners in the cleaning, so that the inside of the grinding cylinder 2 is thoroughly cleaned, further improving the cleaning effect, and ensuring that the inside of the equipment is clean before each grinding operation, thereby ensuring the quality of paint grinding.

[0034] Furthermore, the grinding cylinder 2 is provided with a cooling mechanism, which includes a cooling jacket 19 sleeved on the outside of the grinding cylinder 2. The cooling jacket 19 has a cooling water inlet 22 at the top and a cooling water outlet 23 at the bottom.

[0035] In this embodiment, the cooling jacket 19 forms an independent cooling space. Cooling water enters the cooling jacket 19 from the cooling water inlet 22 at the top. During the flow in the cooling chamber 20, it absorbs the heat emitted by the grinding cylinder 2 and then flows out from the cooling water outlet 23 at the bottom. Through this circulating flow, the heat generated during the grinding process can be carried away in a timely and effective manner, preventing the paint raw materials from deteriorating due to excessive temperature.

[0036] Furthermore, a sealed cooling cavity 20 is formed between the inner wall of the cooling jacket 19 and the outer wall of the grinding cylinder 2. The cooling cavity 20 is provided with a plurality of flow guide baffles 21, which are distributed in a spiral shape.

[0037] In this embodiment, the sealed cooling chamber 20 ensures that the cooling water will not leak, thus ensuring a stable cooling effect. The spirally distributed flow guide baffles 21 can guide the cooling water to flow in the cooling chamber 20 along a specific spiral path, increasing the flow path and time of the cooling water in the cooling chamber 20, allowing the cooling water to fully contact the outer wall of the grinding cylinder 2, thereby more effectively absorbing the heat generated during the grinding process and improving the cooling efficiency.

[0038] Furthermore, a filter assembly is installed on the discharge port 6, the filter assembly including a filter sleeve 24 and a filter screen 25 embedded in the filter sleeve 24.

[0039] In this embodiment, when the ground paint flows out of the outlet 6, it first passes through the filter assembly. The filter screen 25 can intercept the impurities remaining in the paint, making the flowing paint purer and improving the quality of the paint.

[0040] Furthermore, the top of the filter sleeve 24 is threaded to the outer wall of the feed inlet 5, and the filter screen 25 is made of a high-strength, corrosion-resistant material.

[0041] In this embodiment, the filter sleeve 24 is connected to the outer wall of the feed inlet 5 by a threaded connection. This connection method is simple and reliable, and facilitates the installation and disassembly of the filter assembly. When the filter screen 25 needs to be cleaned or replaced after a period of use, the filter sleeve 24 can be easily unscrewed from the outer wall of the feed inlet 5 for the corresponding operation.

[0042] The working principle of this utility model is as follows: In use, the paint to be ground is poured into the grinding cylinder 2 through the feed inlet 5. Then, the drive motor 7 is started, which drives the reducer 8 to operate. The reducer 8 then transmits power to the rotating spindle 9, causing the rotating spindle 9 to start rotating. The rotating spindle 9 drives at least two sets of grinding discs 10, which are spaced apart on it, to rotate together. During the rotation, the grinding heads 12 on the grinding discs 10 come into contact with and rub against the paint particles. Since the grinding heads 12 are connected to the grinding base 11 through a movable connecting component, the grinding heads 12 can automatically adjust their angle according to the shape and size of the paint particles, thereby making better contact with the paint particles and achieving uniform grinding of the paint.

[0043] During the grinding process, the cooling mechanism starts working. Cooling water enters the cooling chamber 20 from the cooling water inlet 22 at the top of the cooling jacket 19, flows along the spiral path guided by the spirally distributed guide baffles 21, fully absorbs the heat emitted by the grinding cylinder 2, and then flows out from the cooling water outlet 23 at the bottom, thus circulating to prevent the paint raw materials from deteriorating due to excessive temperature. After the grinding work is completed, the booster water pump 16 is started. The booster water pump 16 pressurizes the cleaning water and delivers it to the cleaning water pipe 17. The water in the cleaning water pipe 17 is delivered to each nozzle 18 through the hollow channel inside the rotating spindle 9. The nozzles 18 spray water evenly on the inner wall of the grinding cylinder 2 to wash away the paint residue adhering to the inner wall of the grinding cylinder 2 and the grinding components 4.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.
