When cleaning the thermal bonding machine, the hot-melt glue heating plate must be separated from the PUR hot-melt glue bucket first. After the PUR hot-melt glue bucket is separated from the heating plate of the PUR hot-melt glue machine, it should be Cut off all power.

When the thermal bonding machine takes off the barrel, the air pressure charged should be gradually pressurized from small to large. Under any circumstances, it is not allowed to directly use the high-pressure gas to directly take off the barrel to avoid accidents.
When the heating plate of the thermal bonding machine is separated from the polyurethane hot-melt glue bucket, before cleaning the residual glue of the PUR hot-melt glue, the special structure on the pressure plate of the PUR hot-melt glue machine must be used to close the channel between the pressure plate and the pump body. Prevent curing.
When cleaning the heating platen of the thermal bonding machine, the staff must wear special high temperature resistant protective clothing and high temperature resistant gloves. Do not let the skin touch the high temperature parts such as the hot melt adhesive bucket, molten PUR hot melt adhesive and heating plate to avoid burns.
When the thermal bonding machine takes off the barrel, the best way is to fill the 55-gallon hot melt glue barrel with dry nitrogen, and avoid using undried compressed air directly. Dry thoroughly. And often check the use of desiccant.
After the thermal bonding machine is separated from the hot-melt glue bucket, the residual PUR hot-melt glue on the hot-melt glue pressure plate must be thoroughly cleaned immediately. Scratched platen Teflon coating.
When cleaning the pressure plate of a thermal bonding machine with a special structure, the heating plate of the PUR hot melt machine cannot completely clean the residual PUR hot melt adhesive in a short time due to the special structure, so dry nitrogen protection must be used when cleaning the residual PUR hot melt adhesive, and The time for cleaning the residual glue shall not exceed 10 minutes, and no hard tools shall be used to clean the heating plate of the PUR hot melt adhesive machine.
After cleaning the pressure plate of the thermal bonding machine, immediately press the pressure plate into a new PUR hot-melt glue bucket to avoid exposing the pressure plate to the air for a long time. When pressing the heating plate into the plastic bucket, 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.
When the pressure plate of the thermal bonding machine is pressed into the rubber barrel, a small amount of silicone oil can be properly smeared on the sealing ring of the pressure plate for lubrication, so as to produce lubrication between the pressure plate and the rubber barrel and protect the use of the sealing ring.
When the heating platen of the thermal bonding machine is pressed into the new polyurethane hot melt adhesive bucket, the overflow valve should be opened to completely remove the residual air in the plastic bucket, and the PUR hot melt adhesive with air bubbles should be removed to avoid air The polyurethane hot melt adhesive flows into the throat of the pump body hot melt adhesive machine.
After the pressure plate of thermal bonding machine is placed in the polyurethane hot-melt glue barrel and the air is exhausted, the glue overflow valve is tightly locked. At this time, the air pressure in the stroke cylinder can be appropriately increased to make the work smoother.
After replacing the PUR hot melt adhesive, you must wait for the thermal bonding machine to heat for at least 30 minutes before starting the gear pump and motor. If the gear pump and motor are started immediately, it will damage the melter gear pump and reduce the service life of the melter.
