Description

Technical Field

[0001] This utility model relates to the field of latex paint production technology, specifically to a sanding machine. Background Technology

[0002] Latex paint is a type of water-based coating made by adding pigments, fillers and various additives to synthetic resin emulsion as a base. During the production process, it needs to be ground with a sander to make the latex paint more delicate and uniform.

[0003] Chinese Patent No. CN214599386U discloses a grinding machine for latex paint production, including a chamber. The machine pours latex paint raw materials into the chamber through a feed pipe. A motor drives a rotating rod to rotate, causing a turntable on the outer side of the rod to rotate. The latex paint entering the chamber through the feed pipe falls onto the top of the turntable and flows outward under the centrifugal force generated by the rotation, eventually falling onto the grinding disc below. It then continues to flow downward through a through-hole on the grinding disc to the next turntable, repeating this process until the latex paint reaches the bottom of the chamber. While the latex paint flows between the turntable and the grinding disc, the grinding steel balls on the turntable squeeze and rub the medium flowing between them, achieving a grinding effect. Repeating this grinding process multiple times results in a finer finish for the latex paint, without generating significant noise, achieving excellent performance.

[0004] However, the above technical solution has the following shortcomings: The grinding structure using grinding steel balls and a grinding disc to process latex particles relies on point and line contact between the grinding steel balls and the grinding disc to achieve material grinding, resulting in a very limited effective grinding contact area and low overall grinding efficiency, making it difficult to meet the demands of high-capacity production. Furthermore, the fixed installation positions of the grinding steel balls and the grinding disc in this structure mean that the distance between them cannot be dynamically adjusted according to production needs, causing the equipment to only output grinding products of a single particle size. This makes it difficult to flexibly adapt to multi-specification production requirements, limiting the applicability of the equipment and making it difficult to meet the diverse process needs of modern production.

[0010] Preferably, the adjustment mechanism includes an adjustment box, a partition plate, an adjustment cylinder, a lifting rod, and an adjustment assembly; the adjustment box is fixedly connected to the mounting box, the partition plate is fixedly installed inside the adjustment box, the drive shaft passes through the mounting box and the adjustment box and extends into the adjustment box, the adjustment cylinder is rotatably installed inside the adjustment box and rotatably connected to the partition plate, the adjustment assembly is installed inside the adjustment cylinder, one end of the adjustment assembly is connected to the adjustment cylinder, the other end of the adjustment assembly passes through the adjustment box and extends to the outside of the adjustment box, one end of the lifting rod is installed inside the adjustment cylinder, the other end of the lifting rod passes through the partition plate and is slidably connected to the partition plate, and the lifting rod is rotatably connected to the drive shaft.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This invention utilizes a surface-like contact between the annular grinding seat and the grinding roller to significantly increase the effective contact area during material grinding, reduce grinding dead angles, and rapidly grind latex paint raw materials, thereby significantly improving overall grinding efficiency and better adapting to high-capacity production scenarios. Through the coordinated design of the adjustment mechanism, drive mechanism, and grinding mechanism, the grinding gap can be flexibly changed. Adjustment is achieved simply by rotating the adjusting worm gear, which drives the adjusting cylinder to rotate through meshing, and then the lifting rod pushes the drive shaft up and down, ultimately changing the distance between the grinding roller and the annular grinding seat. This design breaks the limitation of fixed grinding gaps in traditional equipment, allowing for dynamic adjustment of the grinding gap according to production needs, and enabling the output of grinding products with different particle sizes.
