Description

Technical Field

[0001] This utility model relates to the field of coating grinding technology, and in particular to a paint grinding device. Background Technology

[0002] Paint and coating grinding equipment is a specialized device used to process paints and coatings. Its core function is to disperse pigment particles and fillers in materials evenly through the high-frequency impact and shearing action of grinding media, reducing particle size and improving the fineness, gloss, and stability of coatings. Its working principle is based on mechanochemical effects. The motor drives the stirring shaft to rotate the dispersing disc at high speed, causing the media and materials in the grinding chamber to generate strong relative motion, breaking up pigment agglomerates and achieving full mixing of the solid and liquid phases, laying the foundation for subsequent coating processes. According to the differences in grinding methods and structures, they are mainly divided into two categories: sand mills and ball mills. Sand mills adopt a vertical or horizontal closed cavity design, while ball mills drive the grinding balls through a rotating drum. Although the production cycle is longer, these devices are widely used in the fields of coatings, inks, and pigments, especially in the production of high-end coatings. Precise control of grinding parameters can directly affect the performance of the final product, such as the smoothness of the coating of architectural coatings and the color uniformity of metallic paints.

[0003] A search revealed Chinese Patent Publication No. CN215783784U, which discloses a paint grinding machine with a cooling device. This machine belongs to the category of paint grinding equipment and includes a base plate, a scraper / feeding device, a cooling paint tank device, a grinding device, and a loading tank. The scraper / feeding device is mounted on the base plate, and the loading tank is positioned on the base plate below the scraper / feeding device. The cooling paint tank device is mounted above the scraper / feeding device, and the grinding device is mounted on top of the scraper / feeding device and above the cooling paint tank device. This device can grind paint coatings... During the grinding process, the paint coating generates high temperatures. The paint cooling tank device can cool the paint coating. After grinding, the scraper discharge device can discharge the paint coating from the cooled paint coating tank into the loading tank. At the same time, it can scrape off the paint coating remaining on the scraper discharge device to prevent paint coating from accumulating and affecting the subsequent grinding effect. Although this device can scrape off the paint coating remaining on the scraper discharge device to prevent paint coating from accumulating and affecting the subsequent grinding effect, it cannot solve the problems of high energy consumption and rapid wear of the grinding media, which leads to frequent maintenance and replacement.

[0051] Working principle: First, the protective cover 12 is opened, and then the raw material is added into the inside of the cylinder 1 through the feed port 11.

Suitable small particles will fall through the feed port 204, and the remaining particles will continue to be ground. At the same time, the circulating water pump 9 draws out the coolant inside the cooling tower 5 and cools the inside of the cylinder 1 through the water pipe 8. Then the coolant flows back into the inside of the cooling tower 5 through the other end of the water pipe 8. At this time, it is cooled down by the cooling plate 6 inside the cooling tower 5. This realizes the function of quickly grinding the raw material and improving its grinding efficiency through cooling.

[0052] When the raw material falls into the cylinder 1 through the feed port 11, it hits the top of the conical disc 301. Then the conical disc 301 will slide along the limiting post 304. At this time, the conical disc 301 will compress the spring 305 to buffer it. At the same time, the sliding ring 302 at the bottom of the conical disc 301 will slide along the annular groove 303 inside the fixed ring 4. Since the top of the conical disc 301 is inclined, it can effectively prevent the raw material from stacking inside the cylinder 1, thus buffering the raw material, preventing damage to the device, and preventing the raw material from stacking.
