When the pur hot melt adhesive machine of the heating plate and the pressure plate is separated from the polyurethane hot melt adhesive barrel, the special mechanism on the pressure plate must use the closing of the pur hot melt adhesive machine, and the remaining pur hot melt adhesive machine of the pressure plate and the pump body before cleaning. Prevent solidification between channels.

4.当清洗加热滚筒的PUR热熔胶机,员工须佩戴特殊的高温防护服和高温手套,和不允许皮肤接触的热熔塑料筒,熔融PUR热熔胶,高温加热板等部件。，以避免烧伤。

4. When cleaning pur hot melt adhesive machine of heating roller, employees must wear special high temperature protective clothing and high temperature gloves, hot melt plastic cylinder which is not allowed to contact with skin, PUR hot melt adhesive, high temperature heating plate and other parts., To avoid burns.

5.PUR热熔胶机卸胶桶时，办法是将5加仑的热熔胶桶装满干燥的氮气，避免直接使用未干燥的压缩空气。如果需要填充压缩空气，压缩空气需要干燥。并经常检查干燥剂的使用情况。

5. When unloading the glue barrel of PUR hot melt glue machine, the method is to fill the 5-gallon hot melt glue barrel with dry nitrogen to avoid direct use of dry compressed air. If compressed air needs to be filled, the compressed air needs to be dried. And often check the use of desiccant.

6.PUR热熔胶机与热熔胶桶分离后，须立即清洗热熔胶压板上剩余的PUR热熔胶。在清洗PUR热熔胶机的热熔胶板时，不要使用任何坚硬的工具，以免刮伤特氟龙涂层的压板。

6. After the pur hot melt adhesive machine is separated from the hot melt adhesive barrel, the remaining pur hot melt adhesive on the hot melt adhesive pressing plate must be cleaned immediately. When cleaning the hot-melt adhesive plate of PUR hot-melt adhesive machine, do not use any hard tools to avoid scratching the Teflon coated pressing plate.

7.清洗时压盘PUR热熔胶机的特殊结构,因为PUR热熔胶机的加热板的特殊结构不能完全清理残余PUR热熔胶在很短的时间内,须清理残余PUR热熔时干。氮气保护，残留胶水的清洗时间不应超过10分钟。不要使用任何坚硬的工具清洁PUR热熔机的加热板。

7. Special structure of press plate pur hot melt adhesive machine when cleaning, because the special structure of the heating plate of PUR hot melt adhesive machine can not completely clean up the residual pur hot melt adhesive. In a very short time, it is necessary to clean up the residual pur hot melt adhesive when it is dry. Nitrogen protection, residual glue cleaning time should not exceed 10 minutes. Do not use any hard tools to clean the heating plate of PUR hot melt machine.

8.清洗完pur热熔胶机的压板后，立即将压板压入新的pur热熔胶桶中，避免让压板长时间暴露在空气中。将加热板压入胶筒时，升降缸的气压应由小到大，不应直接使用高压气体，以免发生事故，并注意操作人员的。

8. After cleaning the pressing plate of PUR hot melt adhesive machine, press the pressing plate into the new pur hot melt adhesive barrel immediately to avoid exposing the pressing plate to the air for a long time. When the heating plate is pressed into the rubber cylinder, the air pressure of the lifting cylinder should be increased from small to large. High pressure gas should not be used directly to avoid accidents, and the safety of operators should be paid attention to.

9.将PUR热熔胶机压板压入胶桶时，在压板密封圈上适当涂抹少量硅油。

9. When pressing the press plate of PUR hot melt adhesive machine into the rubber barrel, apply a small amount of silicone oil on the seal ring of the press plate.

润滑使压板与胶筒之间润滑，以保护密封圈的使用。

Lubrication makes the pressure plate and rubber cylinder lubricated to protect the use of sealing ring.

10.PUR热熔胶机的加热压板压入新型聚氨酯胶桶后，应打开溢流阀，将胶桶内的残余空气完全排出，和带气泡的PUR热熔胶应，以避免带空气的聚氨酯热熔胶流入泵体和热熔胶机喉部。

10. After the heating pressing plate of PUR hot melt adhesive machine is pressed into the new polyurethane adhesive barrel, the overflow valve shall be opened to completely discharge the residual air in the barrel, and the pur hot melt adhesive with bubbles shall be removed, so as to prevent the polyurethane hot melt adhesive with air from flowing into the pump body and the throat of the hot melt adhesive machine.

11.将PUR热熔胶机的压板放入聚氨酯热熔胶桶中，排出空气，然后锁住溢流阀。此时可适当提高行程缸内的气压，使工作更加顺畅。

11. Put the pressure plate of PUR hot melt adhesive machine into the polyurethane hot melt adhesive barrel, exhaust the air, and then lock the relief valve. At this time, the air pressure in the stroke cylinder can be appropriately increased to make the work more smooth.

12.更换PUR热熔胶后，须等待PUR热熔胶机加热少20分钟后才能启动齿轮泵和电机。如果齿轮泵和电机立即启动，会损坏熔炼机的齿轮泵，减少熔炼机的使用。

12. After replacing pur hot melt adhesive, it is necessary to wait for PUR hot melt adhesive machine to heat for at least 20 minutes before starting gear pump and motor. If the gear pump and motor are started immediately, the gear pump of smelting machine will be damaged and the use of smelting machine will be reduced.
