Usage and daily maintenance of PUR hot melt adhesive laminating machine :

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

　　1. When installing the hot melt applicator, 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 component protected by an insulator on the hot melt glue machine may still form a voltage conductor and cause electric shock.

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

　　3. Ensure that the external voltage connected to the hot melt glue machine is in line with the hot melt glue machine itself, such as a single-phase 220v voltage standard hot melt glue machine equipment. If 380V power is used, the hot melt glue machine spraying equipment, such as single phase If the 220v voltage standard hot melt glue machine equipment uses a power supply lower than 220V, the design performance of the equipment cannot be achieved, and the hot melt glue machine may be damaged. When wiring, ensure that the power cord is correctly connected to the location of the external circuit breaker .

　　4. Ensure that the hot melt machine is operated under the specified voltage. If the voltage used is different from the specified voltage, the hot melt machine may be burnt.

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

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

　　2. Do not operate and use the hot melt glue machine without proper protection devices, good insulators or good protection panels. When maintenance is required, only professionally trained personnel can disassemble the machine for maintenance.

　　3. Do not operate the hot melt glue machine in the surrounding environment where the temperature is lower than 0℃ and the temperature is higher than 50℃.

　　4. Try to use it in places without fast flowing air. Because when the hot-melt glue nozzle assembly is exposed to fast-circulating air, the rapid cooling will affect the hot-melt glue flow rate of the nozzle assembly, which is prone to wire drawing.

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

　　6. The amount of replenishing 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 laminating machine:

　　1. When operating the hot melt glue machine, do not place other sundries on the body or use it as a booster.

　　2. When moving or lifting the hot melt glue machine, only its base is allowed to be used as a carrying point. Never use the glue pot cover of the hot melt glue machine, electrical box doors, electrical components on the control panel, or insulation pipes The hot melt glue machine is lifted as an aid by the connector, and abnormal handling will damage the spraying equipment of the hot melt glue machine.

　　4. Safety matters during maintenance and repair of hot melt glue spraying equipment

　　When maintaining the hot melt adhesive machine, the following main safety precautions should be taken:

　　1. Before the maintenance work of the hot melt adhesive machine, the power supply on the hot melt adhesive machine and the main power supply connected to the outside must be cut off, and no live operation is allowed.

　　2. When performing disassembly, maintenance and repair work, it is best for workers not to wear earrings, watches, necklaces, bracelets and other conductive accessories to prevent accidents.

　　3. Do not disassemble, inspect and adjust any parts of the hot melt glue machine at will, unless you have enough knowledge of the equipment's performance.

　　4. Unless there are other people nearby to assist, and in the event of an accident, mechanical damage or personal injury, you can immediately give help or first aid, otherwise do not disassemble and repair the hot melt glue machine equipment alone.

　　5. Only qualified personnel can perform maintenance work on the hot melt glue machine.

　　6. Under any circumstances, do not arbitrarily touch the wire connectors that may be exposed to the outside world or other components that have wire connections and are not loose.

　　7. Before disassembling or moving the protective device on the hot melt glue machine or replacing the components, the power supply must be cut off.

　　8. If possible, try to stand on the plastic blanket for maintenance work. Never perform maintenance work on the hot melt glue machine on a flooded floor or in a very humid environment.

　　8. You must wear safety gloves, goggles and long-sleeved overalls when maintaining and repairing the hot melt glue machine to avoid scalding your body parts by the hot liquid hot melt or burnt by the hot component surface.

　　9. When loosening or installing the pressure joint, it must be determined that the pressure of the pressure air source for the hot melt glue machine 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-sticky coating inside the plastic bucket.

　　11. If air pressure or hot melt glue machine leakage occurs, never continue to operate the hot melt glue machine. First stop the hot melt glue machine, cut off the power supply, and reduce the operating pressure to zero before performing maintenance.
