Details of surface cleaning work of hot melt adhesive machine

The hot melt glue machine is equipped with a glue box. After the glue box has been used for a period of time, we can see with the naked eye that there is a layer of black carbonized material on the cylinder wall of the glue barrel. If you do not pay attention and ignore the cleaning of the surrounding environment of the workpiece, the workpiece is in danger of being contaminated when painting. The oil, dust and dirt on the surface of the workpiece of the hot melt glue machine are the enemies of coating construction. If the surface of the workpiece cannot be cleaned before painting, coating failure will be inevitable.

Before cleaning the hot melt glue machine equipment, you first need to heat the machine to the operating temperature, drain the remaining hot melt glue in the machine, and then pour in a special cleaning agent, such as cleaning oil, which is very convenient and quick. Then connect the hot melt glue hose and the hot melt glue gun, pass the cleaning agent through the hot melt glue hose and the hot melt glue gun, and clean the residual glue inside. In addition, the filter screen in the hot melt glue machine and the hot melt glue gun should be taken out and cleaned regularly. For the filter screen that has been used for too long or severely worn, a new filter screen can be replaced.

Please follow the steps below to clean the hot melt glue machine:

1. Wear a scalding shield and gloves.

2. Heat the hot melt glue machine to 130-150 degrees, and release some pressure from the pressure valve of the main machine to avoid excessive pressure and glue scalding people. Then remove the hot melt glue hose to remove the remaining hot melt glue in the glue box. At this time, be sure to use a clean container to catch the glue (the glue can be used again after it dries), but do not mix impurities to block the glue machine.

3. Use tools to remove the filter in the hot melt glue machine equipment and clean it (the maintenance knowledge of the glue has a clear description of the steps on how to clean the main machine filter).

4. Pour the cleaning agent into the glue barrel and add a small amount of hot melt glue to melt and then remove it together.

5. Reinstall the filter in the hot melt glue machine, connect the hot melt glue hose and glue gun, and re-add hot melt glue for use.
