Description
Technical Field
[0001] The utility model relates to the technical field of abrasive cloth synthesis, in particular to an air suction device for abrasive cloth synthesis. Background Art
[0002] Emery cloth is a type of abrasive tool made by evenly applying abrasive to a solid cloth base. It is primarily used to remove rust, paint, or burrs from metal surfaces, as well as to polish surfaces. It can also be used to polish non-metallic materials such as bone. Emery cloths vary in grit size and come in different grades to meet different polishing requirements. The base fabric can be made of cotton, which offers strength and flexibility, making it easier to polish curved surfaces. The main difference between emery cloth and sandpaper lies in their base materials and applications. Sandpaper uses abrasive bonded to a paper base with an adhesive, while emery cloth uses abrasive bonded to a cloth base. Sandpaper has a finer abrasive grit, resulting in a more delicate polishing effect, while emery cloth has a coarser abrasive grit, resulting in faster polishing but lower precision. This makes emery cloth primarily used for rough finishing of metal and wood, while sandpaper is suitable for intermediate and fine polishing of metal, wood, painted surfaces, and composite materials.
[0003] The production process of abrasive cloth involves several key steps: first, preparing the required materials, then processing the base cloth, applying abrasive, then curing, and finally finishing the finished product. The key role of the coating step is to evenly apply the graded abrasive to the base cloth. After the abrasive is applied, adhesive is sprayed onto the base cloth to secure the abrasive to the cloth. Next, the coated cloth undergoes a curing process to solidify the adhesive, ensuring its strength and wear resistance. Curing methods for abrasive cloth mainly include drying chamber curing and suction curing. Drying chamber curing involves continuously conveying the abrasive cloth forward using rollers, then continuously baking and heating it within the drying chamber to achieve the desired curing effect. While this manufacturing process offers advantages such as simple equipment and ease of operation, abrasive droplets are unavoidable during the transportation of the coated cloth to the drying chamber, affecting its quality. For this reason, before the emery cloth is sent into the drying room, it is pre-cured using a suction cylinder. The suction cylinder uses a vacuum pump to create a negative pressure environment for the adsorption holes opened by the suction cylinder, so that the emery cloth wrapped on the suction cylinder can be quickly dried. At the same time, because the emery cloth is under negative pressure, it can press the abrasive to the base, thereby improving the quality of the emery cloth synthesis. Since the vacuum pump can only create a negative pressure environment around the adsorption holes, it is impossible to fully cure the emery cloth wrapped in the suction cylinder, so it is difficult to ensure the pre-curing effect of the emery cloth. Therefore, there is room for improvement in the pre-curing of emery cloth in emery cloth production to reduce the occurrence of abrasive falling, thereby improving the quality of emery cloth synthesis.
