Description

Technical Field

[0001] The present invention belongs to the technical field of sandpaper production, and particularly relates to an automated production and packaging system and a packaging method for environmentally friendly water-based green sandpaper. Background Art

[0002] Environmentally friendly water-based green sandpaper is a product made of environmentally friendly materials and minimizing environmental impact during processing. This kind of sandpaper has various uses and is widely used in fields requiring fine grinding, surface treatment, and high environmental protection requirements. The following are some of the main uses: 1) Home decoration and maintenance: In home decoration projects such as furniture renovation, wooden floor grinding, and door and window trimming, environmentally friendly water-based green sandpaper can provide a delicate grinding effect while reducing the release of harmful dust, protecting the health of residents. 2) Automobile beauty and maintenance: Used for repairing minor scratches on the car body, polishing the paint surface, and fine grinding of plastic parts such as bumpers. Its environmental protection characteristics ensure that while restoring the beauty of the vehicle, it does not cause additional burdens to the environment and users. 3) Art and handicraft production: During the processing of artworks such as wood carving, stone carving, and metal handicrafts, environmentally friendly water-based green sandpaper can help artists achieve fine texture processing and surface smoothness while maintaining a clean and safe working environment. 4) Electronics and precision instrument manufacturing: Suitable for edge treatment of circuit boards, fine grinding of small metal parts, and polishing of non-metal materials such as optical lenses and glass, ensuring high-precision requirements while meeting environmental protection standards during the production process. In short, environmentally friendly water-based green sandpaper plays an important role in multiple fields with its characteristics of environmental protection, high efficiency, and safety, not only improving work efficiency and product quality, but also promoting the dual goals of environmental protection and human health.

[0003] Existing automated production and packaging systems for environmentally friendly water-based green sandpaper have deficiencies. One is that their production and packaging operations are cumbersome, and the production and packaging efficiency is relatively low. The other is that the abrasive is exposed after the sandpaper is packaged, which leads to easy contact and friction between the abrasive and the packaging film, resulting in damage to the packaging film and also easy wear of the abrasive during transportation and other adverse effects. Therefore, it needs to be optimized and improved. Summary of the Invention
