TECHNICAL FIELD
[0001] The utility model relates to sandpaper manufacturing technical field, specifically point to a kind of composite gluing mechanism for manufacturing sandpaper. BACKGROUND
[0002] Sandpaper is a tool used for grinding and polishing. It is made by adhering abrasive material to a paper base. The abrasive material, usually silicon carbide, alumina, etc., is highly hard and can effectively grind the surface of an object. The paper base provides support and flexibility, allowing the sandpaper to conform to different shapes of objects. Sandpaper comes in various grades, distinguished by grit size, with higher grit numbers indicating finer sandpaper. For example, 800-grit sandpaper produces a smoother surface than 200-grit sandpaper. It is widely used in woodworking, metalworking, automotive repair, home decoration, and other fields.
[0003] During the production of sandpaper, the base paper needs to be coated with glue before the abrasive particles are attached. Current sandpaper coating structures use a process of coating the glue and then applying a uniform coating process to ensure that one side of the base paper is evenly coated. However, existing uniform coating methods rely heavily on uniform coating rollers. Even so, it is still difficult to ensure absolute uniformity of the coating, and there are often situations where the glue layer in certain areas is thicker. Furthermore, during the uniform coating process, excess glue often flows out of the edges of the base paper. This flowing glue can drip onto the workbench, causing contamination. Once the glue solidifies, it adheres tightly to the workbench, making it extremely difficult to clean. SUMMARY
[0004] The utility model provides a kind of composite gluing mechanism for manufacturing sandpaper, which can coat glue more evenly and facilitate the collection of excess glue.

[0031] Specific implementation of the utility model: firstly, the sandpaper raw paper is introduced into the glue applying table 1 through the guide rollers 2 at the two ends of the glue applying table 1, so that the raw paper passes around the two guide rollers 2, and passes through the glue spraying pipe 4, the glue pushing plate 5 and the bottom of the leveling roller 6 in the middle.
