1. Safety matters during installation of PUR hot melt adhesive compound machine
1. When installing the PUR hot melt adhesive compound machine, a correct and effective grounding wire must be connected. Any equipment that uses high voltage electricity needs to have a grounding wire. When the grounding wire is not used, any PUR hot melt adhesive compound machine has insulator protection components, which may still form a voltage conductor and cause the risk of electric shock.
2. According to the load required by the PUR hot-melt adhesive compound machine and its auxiliary peripheral equipment, check whether the power cord used and the insulation protection meet the regulations. The load of the wire must be higher than the rated power of the PUR hot-melt adhesive compound machine.
3. Make sure that the voltage connected to the PUR hot-melt adhesive compound machine from the outside world is consistent with the PUR hot-melt adhesive compound machine itself. For example, if the single-phase 220v voltage standard PUR hot-melt adhesive compound machine equipment uses 380V power supply, the PUR hot-melt adhesive will be damaged. Composite machine spraying equipment, such as single-phase 220v voltage standard PUR hot-melt adhesive compound machine equipment, if the power supply is lower than 220V, the equipment design performance cannot be achieved, and the PUR hot-melt adhesive compound machine may be damaged. When wiring, ensure that its power supply The line is correctly connected to the position of the external circuit breaker.
4. Make sure that the PUR hot-melt adhesive compound machine is operated at the specified voltage. If the voltage used is different from the specified voltage, it may cause the PUR hot-melt adhesive compound machine to be burned.
2. Safety matters during daily operation of PUR hot melt adhesive compound machine
1. Avoid operating the PUR hot melt adhesive compound machine around volatile and explosive raw materials or gases. Inflammable and explosive materials cannot be stored around the spraying equipment of the PUR hot melt adhesive compound machine.
2. Do not operate the PUR hot melt adhesive compound machine without proper protective devices, good insulators or good protective panels. Only professionally trained personnel can disassemble and repair the machine when maintenance is required.
3. Do not operate the PUR hot melt adhesive laminating machine in an environment where the temperature is lower than 0°C and the temperature is higher than 50°C.
4. Try to use it in places where there is no fast flowing air. Because when the hot-melt adhesive nozzle assembly is exposed to the fast-circulating air, the rapid cooling will affect the hot-melt adhesive flow of the nozzle assembly, and it is easy to cause stringing.
5. When adding hot melt adhesive, it should be added before there is at least one-third of the hot melt adhesive in the melt adhesive pot, so as to avoid adding glue when there is no hot melt adhesive in the hot melt adhesive pot, which will affect normal production.
6. The amount of supplementary glue shall not exceed 80% of the total volume of the hot melt glue pot.
3. Matters needing attention when using PUR hot melt adhesive compound machine
1. When operating the PUR hot-melt adhesive compound machine, do not place other sundries on the machine body or use it as a heightening device.
2. When moving or lifting the PUR hot-melt adhesive compound machine, only its base is allowed to be used as a moving point. Never use the plastic pot cover, electrical box door, and electrical components on the control panel of the PUR hot-melt adhesive compound machine. Or the joint on the insulation pipe is used as an auxiliary to lift the PUR hot melt adhesive compound machine. Abnormal handling will damage the PUR hot melt adhesive compound machine spraying equipment.
4. Safety matters during maintenance and repair of PUR hot melt adhesive compound machine spraying equipment
When maintaining and repairing the PUR hot melt adhesive compound machine, the following main safety precautions should be taken:
1. Before maintenance and repair of the PUR hot-melt adhesive compound machine, the power supply on the PUR hot-melt adhesive compound machine and the total power supply connected to the outside world must be cut off first, and no live operation is allowed.
2. When disassembling, maintaining and repairing, workers should not wear earrings, watches, necklaces, bracelets and other conductive decorations to prevent accidents.
3. Do not disassemble, check and adjust any parts on the PUR hot melt adhesive compound machine unless you have sufficient understanding of the performance of the equipment.
4. Do not disassemble and repair the PUR hot melt adhesive compound machine alone unless there are other people assisting, and in the event of an accident, mechanical damage or personal injury, immediate help or first aid can be given.
5. Only qualified personnel can perform maintenance work on the PUR hot melt adhesive compound machine.
6. In any case, do not touch the wire connectors that may be exposed to the outside world or other components that have wires connected and are not loose.
7. Before removing or moving the protective device on the PUR hot melt adhesive compound machine or replacing components, the power supply must be cut off first.
8. If possible, try to stand on the plastic blanket for maintenance and repair work. Never perform maintenance work on the PUR hot melt adhesive laminating machine with flooded floors or in very humid environments.
9. Safety gloves, goggles and long-sleeved overalls must be worn when maintaining and repairing the PUR hot-melt adhesive compound machine to avoid body parts being burned by high-temperature liquid hot-melt glue or burned by high-temperature component surfaces.
10. When loosening or installing the pressure joint, it must be confirmed that the pressure of the pressure source for the PUR hot melt adhesive compound machine has been reduced to zero.
11. When cleaning the PUR hot melt glue tank, avoid using fireworks or sharp hard tools to avoid scratching the Teflon non-stick coating inside the glue tank.
12. If air pressure or PUR hot melt adhesive compound machine leakage occurs, do not continue to use the PUR hot melt adhesive compound machine, first stop the PUR hot melt adhesive compound machine, cut off the power supply, and reduce the operating pressure to zero value and then overhaul.
