Safety Matters When Installing The Hot Melt Adhesive Laminating Machine.

Safety matters when installing the hot melt adhesive laminating machine.


1. When installing the hot 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, without the use of a grounding wire, any hot melt adhesive machine with insulator protection of the components, there may still form a voltage conductor, the risk of electric shock.



2. According to the load required by the hot melt glue machine and its affiliated peripheral equipment, check the power cord used, and insulation protection is in line with the provisions of the conductor load must be higher than the rated power of the hot melt glue machine.



3. make sure the external voltage connected to the hot melt adhesive machine is in line with the hot melt adhesive machine itself, such as 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 single-phase 220v voltage standard hot melt adhesive machine equipment, if the use of less than 220V power supply, can not reach the design performance of the equipment, but also may damage the hot melt adhesive machine, the connection should be to ensure that the power cord is correctly connected to the outside world, and insulation protection. When wiring, make sure the power cord is correctly connected to the position of the external disconnector. 4.



4. ensure that the hot melt adhesive machine in the specified voltage operation, if the voltage used is different from the specified, may cause the hot melt adhesive machine is burned.




Second, the hot melt adhesive laminating machine daily operation of the safety matters


1. avoid operating the hot melt adhesive machine around volatile and explosive materials or gases, hot melt adhesive spraying equipment can not be stored around flammable and explosive substances.



2. Do not operate the hot melt adhesive dispenser without proper protection devices, good insulation or good protection panels, and only professionally trained personnel should disassemble the dispenser for maintenance when it needs to be serviced.



3. Try to use the machine without fast moving air. Because when the hot melt nozzle combination is exposed to fast flowing air, the rapid cooling will affect the flow of hot melt adhesive in the nozzle combination, which will easily produce the phenomenon of wire drawing.



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



5. The amount of supplemental glue shall not exceed eighty percent of the total volume of the hot melt glue pot.




Third, the hot melt adhesive laminating machine in the use of matters to be noted.


1. When operating the hot melt adhesive machine, do not put other sundry objects on the body or use it as a height-padded device. 2.



2. moving or lifting the hot melt adhesive machine, only allowed to use its base as the handling point of gravity, never use the hot melt adhesive machine glue pot cover, electrical box door, control panel on the electrical components or insulation pipe on the joints as an aid to lift the hot melt adhesive machine, non-normal handling will be damaged by hot melt adhesive machine spraying equipment.



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



1, in the maintenance and repair of hot melt adhesive machine before the work, must be the hot melt adhesive machinery on the power supply and connection to the outside world to cut off the total power supply, do not operate with electricity.



2. in the dismantling of maintenance and repair work, it is best not to wear earrings, watches, necklaces, bracelets and other decorations that can be conductive, to prevent accidents.



3. Unless there are other people in the side to assist, and in the event of an accident, due to mechanical damage or injury to the personnel, can immediately give help or first aid, otherwise do not be alone on the hot melt adhesive machine equipment disassembly and maintenance.



5. Do not, under any circumstances, touch wire connectors or other components that may be exposed to the outside world and have wires connected to them that have not been loosened.



6. Disconnect the power supply before disassembling or moving the protective devices or replacing the components of the hot melt dispenser.



7. Wear safety gloves, goggles, and long-sleeved overalls when servicing or repairing the hot melt adhesive dispenser in order to avoid burns from the hot liquid hot melt adhesive, or burns from the hot component surfaces.



8. When loosening or installing pressure fittings, make sure that the pressure of the air supply for the hot melt dispenser has been reduced to zero.



9. Avoid using flaming or sharp hard tools when cleaning the hot melt adhesive cylinder to avoid scratching the Teflon nonstick coating on the inside of the drum.



10. If air pressure or hot melt glue machine leakage occurs, do not continue to operate the hot melt glue machine, first of all, stop the hot melt glue machine work, cut off the power supply, and will operate the pressure down to zero value and then carry out maintenance.
