In the production process of the corrugated cardboard box-gluing machine, the control of the amount of glue applied is a crucial link. The amount of glue applied directly affects the bonding strength, appearance quality and production efficiency of the carton. Therefore, mastering how to control the amount of glue applied by the corrugated cardboard box-gluing machine is of great significance for improving product quality and production efficiency.

1.Factors affecting the amount of glue applied

The amount of glue applied is affected by many factors, including cardboard material, carton shape, glue type, glue application speed, etc. Different materials of cardboard have different abilities to absorb glue, and the shape of the carton will also affect the uniformity and amount of glue applied. In addition, different types of glue have different viscosities and fluidities, which will also affect the amount of glue applied. Therefore, these factors need to be considered comprehensively when controlling the amount of glue applied.

2.How to control the amount of glue applied

Adjust the gap of the glue coating wheel: The glue coating wheel is a key component to control the amount of glue applied. By adjusting the gap between the glue coating wheel and the cardboard, the thickness of the glue can be controlled. If the gap is too large, the amount of glue applied is too little; if the gap is too small, the amount of glue applied is too much. Therefore, it is necessary to adjust the gap of the rubber coating wheel according to the actual production situation to achieve the appropriate glue coating amount.

Control the glue application speed: The speed of glue application will also affect the amount of glue applied. If the glue application speed is too fast, the glue may not be fully applied to the cardboard; if the glue application speed is too slow, it may cause excessive accumulation of glue. Therefore, the glue coating speed needs to be set reasonably according to the production speed and cardboard characteristics.

Choose the right glue: Different types of glue have different viscosities and flow properties. When choosing glue, you need to consider factors such as cardboard material, carton shape, and production environment to select a suitable glue type. At the same time, the glue is tested and replaced regularly to ensure stable glue quality.
