1. When the press plate of PUR hot melt glue machine is removed from the barrel, the air pressure filled should be slowly pressurized from small to large, and the hot melt glue machine is not allowed to directly use high pressure gas directly from the barrel in any case to avoid accidents.
2, cleaning PUR hot melt glue machine heating pressure plate, the staff must wear special high-temperature hot melt glue machine protective clothing, with high-temperature gloves, do not let the skin contact hot melt glue barrel, molten PUR hot melt glue and heating plate and other high-temperature parts, to avoid burns.
3. After the press plate of the PUR hot melt adhesive machine is separated from the hot melt adhesive barrel, the residual PUR hot melt adhesive on the hot melt adhesive press plate must be cleaned immediately. When cleaning the hot glue plate of the PUR hot melt adhesive machine, no hard tools can be used to prevent scratching the Teflon coating of the press plate. The cleaning time of PUR glue should not exceed 10 minutes.
4. After cleaning the press plate of the PUR hot melt glue machine, the press plate should be pressed into the new PUR hot melt glue barrel immediately to avoid exposing the press plate in the air for a long time. When pressing the press disc of PUR hot melt glue machine into the rubber bucket, a small amount of silicone oil can be applied to the sealing ring of the press disc to lubricate it, so that the lubrication between the press disc and the rubber bucket can be generated to protect the use of the seal ring. When the heating disc is pressed into the rubber barrel, the air pressure of the lifting cylinder should be from small to large, and high pressure gas should not be directly used to prevent accidents and pay attention to the safety of the operator.
5, when the PUR hot melt rubber machine heating pressure plate is pressed into the new polyurethane rubber barrel, the overflow valve should be opened to discharge the residual air in the rubber barrel, and the PUR hot melt rubber with air bubbles should be removed clean, to avoid the polyurethane hot melt rubber with air into the pump body and the hot melt rubber machine pipe. After the PUR hot melt glue press plate is placed into the polyurethane hot melt glue barrel and the air is removed, the overflow valve is locked, and the air pressure in the stroke cylinder can be appropriately increased at this time to make the work more smooth.
6, after replacing the PUR hot melt glue, you must wait for the PUR hot melt glue machine to heat at least 20 minutes before starting the gear pump and motor, such as immediately starting the gear pump and motor will cause damage to the gear pump of the rubber machine and reduce the service life of the rubber machine.
