1.Al limpiar elfundidor a granel pur, the heating plate of the glue machine must be separated from the pur hot melt glue barrel, and all power supplies must be cut off while maintaining the pressure in the lifting cylinder. When the fundidor a granel pur is taking off the barrel, the air pressure should be increased slowly from small to large. It is not allowed to use high-pressure gas directly to take off the barrel, which is very dangerous and may cause accidents.


2. When cleaning the heating platen of the fundidor a granel pur, you must wear special high-temperature protective clothing and high-temperature gloves. Do not let the skin contact the hot-melt adhesive barrel, molten pur hot-melt adhesive and heating plate and other high-temperature parts to avoid burns.

3. Cuando la fundición a granel pura se despega del barril, es necesario llenar el barril con aire seco, evitar usar aire comprimido sin secar directamente y verificar el uso de desecante con frecuencia.


4. Después de separar el fusor purbulk del cilindro de cola termofusible, el pegamento termofusible puro que queda en la placa de presión de la máquina de cola termofusible debe limpiarse inmediatamente. Al limpiar la placa de presión de la máquina de pegamento termofusible puro, no se pueden utilizar herramientas duras. , Para evitar rayar la placa de presión Recubrimiento de teflón.


5. After the pressure plate of the fundidor a granel pur is cleaned, a small amount of silicone oil can be properly applied to the sealing ring of the pressure plate for lubrication, and then the pressure plate is immediately pressed into the new pur hot melt adhesive barrel to avoid the pressure plate being exposed for a long time. In the air. When pressing into the heating plate, the air pressure of the lifting cylinder should be from small to large, and high-pressure gas should not be used directly to prevent accidents and pay attention to the safety of operators.


6. When the heating platen of the fundidor a granel pur is pressed into the new rubber bucket, the overflow valve should be opened to completely discharge the residual air in the rubber bucket, and remove the pur hot melt adhesive with air bubbles to avoid The hot melt glue of air flows into the pump body and the throat of the hot melt glue machine. After the air is exhausted, the glue overflow valve is locked.


7. After changing the pur hot melt adhesive, you must wait for the machine to heat up for 20 minutes before starting the gear pump and motor. If the gear pump and motor are started immediately, the polyurethane gear pump will be damaged and the life of the fundidor a granel pur will be reduced.
