Description

Technical Field

[0001] The utility model relates to the technical field of plastic product polishing devices, in particular to a dustproof polishing device for plastic products. Background Art

[0002] Plastic is a polymer material, usually used as raw material for manufacturing various products. During the production process, there may be burrs, bubbles, bumps and other unevenness on the surface of plastic products. These defects not only affect the aesthetics of plastic products, but also affect their quality. In order to make plastic products have better appearance and performance, polishing and grinding are one of the indispensable processes; mechanical polishing is the most commonly used polishing method at present. Mechanical polishing is a polishing method that relies on cutting and plastic deformation of the material surface to remove the polished convex parts to obtain a smooth surface. Generally, oilstone strips, wool wheels, sandpaper, etc. are used, and manual operation is the main method. For special parts such as the surface of rotating bodies, auxiliary tools such as turntables can be used. For high surface quality requirements, ultra-fine grinding and polishing methods can be used.

[0003] After searching, the Chinese patent number is CN208428098U, which includes a base, a cylinder is fixedly connected to the right side of the top of the base, a rotating motor is fixedly connected to the top of the cylinder, a rotating shaft is fixedly connected to the output shaft of the rotating motor, a fixed block is fixedly connected to the left end of the rotating shaft, a fixing groove is provided on the left side of the fixed block, two support blocks are symmetrically arranged on the top of the base and corresponding to the left side of the cylinder, and the tops of the two support blocks are fixedly connected by threaded sleeves. The utility model achieves a good polishing effect through the cooperation of a rotating motor, a rotating shaft, a fixed block, a fixed groove, a supporting block, a threaded sleeve, a sliding groove, a sliding rod, a slider, a forward and reverse motor, a forward and reverse shaft and a threaded rod. It does not require manual polishing, saves time and effort, and reduces the workload of staff. It not only has high polishing efficiency but also ensures product quality, bringing great convenience to manufacturers. However, there is a problem that when polishing plastic pipes, the surface of multiple plastic pipes cannot be polished at the same time, which reduces the working efficiency of the device. At the same time, a large amount of dust will be generated in the entire polishing process and will directly enter the air, reducing the air quality in the surrounding environment. For this reason, we propose a dust-proof polishing device for plastic products. Utility Model Content
