[0002] The gluing device of the water glue machine is a key part of the whole equipment, which is directly related to the coating quality and efficiency of the glue. Generally speaking, the gluing device is composed of a glue tank, a coating roller, a scraper, a glue supply system and other components.

[0003] The glue tank is used to hold glue, and its material usually has good corrosion resistance to adapt to the chemical properties of different glues and ensure that it is not eroded and damaged during long-term use. The coating roller is the core component for achieving uniform glue coating, and its surface process is diverse. Some are treated with special sanding to accurately control the amount of glue adhesion. During rotation, the glue in the glue tank is brought out and evenly coated on the material to be processed. The scraper is arranged next to the coating roller and functions to scrape off the excess glue on the coating roller to make the glue coating thickness accurate to the process requirements. The angle and pressure of the scraper can be flexibly adjusted according to actual gluing needs. The glue supply system is responsible for continuously supplementing glue to the glue tank to ensure the continuity of the gluing operation. It can intelligently control the flow and speed of the glue according to preset parameters. The current existing technology mainly controls the gluing thickness by adjusting the distance between the coating roller and the upper glue roller. The distance between the coating roller and the upper glue roller is usually adjusted by bolts. However, during the operation of the coating roller and the upper glue roller, some vibration will occur, which may cause the bolts to loosen, thereby changing the distance between the coating roller and the upper glue roller.
