Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding technology, specifically to a novel pneumatic grinding machine for central hole seat surfaces. Background Technology
[0002] Sanding is the process of rubbing the surface of an object or coating with abrasive media such as sandpaper, pumice, or fine stone powder. It is an important step in the coating process and is generally done manually, but can also be done with pneumatic or electric equipment. Sanding is an integral part of the entire coating process. Not only do raw materials, priming, and puttying require sanding, but sanding is also necessary after applying the topcoat. Its functions are to remove burrs, loose rust, oil, and dust from the substrate surface; to remove coarse particles and impurities from the coating surface to obtain a smooth surface; and to sand smooth coating surfaces to a certain roughness to enhance coating adhesion. However, existing sanding guns do not have exhaust gas filtration and purification functions during sanding. Secondly, the lack of exhaust gas filtration devices will affect production efficiency and equipment lifespan. If the exhaust gas generated during sanding is not treated in time, it will accumulate in the workshop, affecting the respiratory system and eye health of operators. Long-term exposure may lead to occupational diseases. At the same time, the accumulation of exhaust gas will also affect the normal operation of equipment and reduce production efficiency.

Then, the second electric telescopic rod 19 is started to drive the connecting plate 18 to move forward. The height of the connecting plate 18 is adjusted, which in turn drives the stirring rod 14 to adjust its height. Then, the first electric telescopic rod 17 is activated, which drives the slip ring 13 to move left and right. The left and right movement of the slip ring 13 drives the first motor 16 to move left and right. Then, the first motor 16 is activated, which drives the stirring rod 14 to rotate. The rotation of the stirring rod 14 drives the waste gas and water to purify the water. Then, the delivery pump 20 is activated, which drives the purified air to be transported through the pipeline to the exhaust plate 23. Then, the exhaust plate 23 discharges the waste gas and it undergoes multiple filtration and purification through the filter plate 21.
