How to use and daily maintenance of PUR hot melt adhesive laminating machine

How to use and daily maintenance of PUR hot melt adhesive laminating machine:

1. Safety matters during the installation of PUR hot melt adhesive laminating machine:

1. When installing the melt adhesive machine, a correct and effective grounding wire must be connected. Any equipment that uses high-voltage electricity needs to have a grounding wire, and when the grounding wire is not used, there is still a possibility that a voltage conductor may form a voltage conductor and cause a risk of electric shock if the insulator protection element is not used.

2. According to the load required by the hot melt glue machine and its auxiliary peripheral equipment, check whether the power cord used and the insulation protection meet the regulations, and the load of the wire must be higher than the rated power of the hot melt glue machine.

3. Ensure that the voltage connected to the hot melt adhesive machine is in line with the hot melt adhesive machine itself, such as the single-phase 220V voltage standard hot melt adhesive machine equipment, if the use of 380V power supply will damage the hot melt adhesive machine spraying equipment, such as the single-phase 220V voltage standard hot melt adhesive machine equipment, if the power supply is lower than 220V, can not achieve the design performance of the equipment, may also damage the hot melt adhesive machine, when wiring should ensure that the power cord is correctly connected to the position of the external power breaker.

4. Make sure that the melter is operating at the specified voltage, if the voltage used is different from the specified, it may cause the melter to burn out.

2. Safety matters during the daily operation of PUR hot melt adhesive laminating machine

1. Avoid operating the hot melt adhesive machine around volatile and explosive raw materials or gases, and do not store flammable and explosive materials around the hot melt adhesive machine spraying equipment.

2. Do not operate the hot melt adhesive machine without proper protective devices, good insulators or good protective panels, and only professionally trained personnel can disassemble and repair the machine when it needs to be repaired.

3. Do not operate the hot melt adhesive machine in the surrounding 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 flow of air. Because when the hot melt adhesive nozzle combination is exposed to the rapid circulation of air, due to the rapid cooling, the hot melt adhesive flow rate of the nozzle combination will be affected, and it is easy to produce wire drawing.

5. When replenishing hot melt adhesive, at least one-third of the hot melt adhesive should be added before there is still one third of the hot melt adhesive in the melt glue pot, so as to avoid adding glue when there is no hot melt adhesive in the hot melt glue pot, which will affect the normal production.

6. The amount of refill glue shall not exceed 80% of the total volume of the hot melt glue pot.

3. Matters to be paid attention to when using the PUR hot melt adhesive laminating machine:

1. When operating and using the hot melt adhesive machine, do not place other sundries on the machine or use it as a high-level appliance.

2. When moving or lifting the hot melt adhesive machine, only its base is allowed to be used as the handling force, and the hot melt adhesive machine must not be lifted by using the rubber pot cover, electrical box door, electrical components on the control panel or the joints on the insulation pipe of the hot melt adhesive machine, as abnormal handling will damage the spraying equipment of the hot melt adhesive machine.

Fourth, the safety matters during the maintenance and repair of the glue spraying equipment of the hot melt adhesive machine

When maintaining and repairing the hot melt adhesive machine, the following main safety precautions need to be taken:

1. Before the maintenance and repair of the hot melt adhesive machine, the power supply on the hot melt adhesive machine and the total power supply connected to the outside world must be cut off, and the operation must not be lived.

2. When dismantling and repairing work, it is best not to wear earrings, watches, necklaces, bracelets and other ornaments that can conduct electricity to prevent accidents.

3. Do not disassemble and inspect any parts of the melt machine unless you have enough understanding of the performance of the equipment.

4. Do not disassemble and repair the hot melt adhesive machine equipment alone unless there are other personnel to assist, and in the event of an accident, due to mechanical damage or injury to personnel, help or first aid can be given immediately.

5. Only qualified personnel can carry out maintenance work on the hot melt adhesive machine.

6. Under no circumstances should you touch the wire joints or other unloosened components that may be exposed to the outside world.

7. Before disassembling or moving the protective device on the melter or replacing the components, the power supply must be cut off.

8. If possible, try to stand on the plastic blanket for maintenance and repair work. Never perform maintenance work on a melter on a flooded floor or in a very humid environment.

8. When maintaining and repairing the hot melt adhesive machine, you must wear safety gloves, goggles and long-sleeved overalls to avoid being burned by the high-temperature liquid hot melt or the surface of the high-temperature components.

9. When loosening or installing pressure fittings, make sure that the pressure supplying the melter has been reduced to zero.

10. When cleaning the hot melt glue tank, avoid using fireworks or sharp hard tools to avoid scratching the Teflon non-stick coating inside the rubber drum.

11. If there is air pressure or leakage of the hot melt adhesive machine, do not continue to operate and use the hot melt adhesive machine, first stop the hot melt adhesive machine to work, cut off the power supply, and reduce the operating pressure to zero before maintenance.
