Operation and maintenance of hot melt adhesive coater

Operation and maintenance of hot melt adhesive coater

I. safety Quan matters during daily Cao operation of hot melt adhesive coater

⒈ avoid using Cao as a hot melt adhesive coater around volatile and explosive raw materials or gases. Flammable and explosive materials cannot be stored around the spraying equipment of the hot melt adhesive coater. 2. Do not use the hot melt adhesive coater without proper protection device, good insulator or good protection panel. Only specially Ye trained personnel can dismantle the coater for maintenance when maintenance is required. 3. Do not use hot melt adhesive coater in the surrounding environment where the temperature is lower than 0 ℃ and higher than 50 ℃. 4. Try to use it when there is no fast flowing air. Because when the hot melt adhesive nozzle combination is exposed to the rapidly circulating air, the rapid cooling will affect the hot melt adhesive flow of the nozzle combination, which is easy to produce wire drawing phenomenon. 5. When adding hot melt adhesive, it should be added before Zui less than one third of the hot melt adhesive in the hot melt adhesive pot, so as to avoid adding adhesive when there is no hot melt adhesive in the hot melt adhesive pot, which will affect the normal production. 7. The amount of supplementary glue shall not exceed 80% of the total volume of the hot-melt glue pot.

2、 Maintenance of hot melt adhesive coater

1. Unless you have the assistance of other personnel, Hot melt adhesive coating machine after the accident, due to mechanical damage or personal injury, you can give immediate help or first aid, or do not disassemble and maintain the hot-melt coater equipment alone.

2. Do not disassemble or inspect any he part of the fuser unless you have enough knowledge of the performance of the equipment.

3. Only qualified personnel can work on the maintenance of the hot melt coater

4. Wear Ann Quan gloves, goggles and long sleeved overalls when maintaining and repairing the hot melt adhesive coater to avoid being scalded by high-temperature liquid hot melt adhesive or burned by high-temperature component surface

5. Under any he circumstances, do not touch the connection of electrical or other components whose wires may be exposed to the outside, and do not relax.

6. Before repairing the hot melt adhesive coater, you must first connect the power supply of the hot melt coater and the external main power supply, cut off and do not work with electricity Cao.

7. When cleaning the hot melt glue cylinder, avoid using fireworks or sharp hard tools to avoid scratching the Teflon non adhesive coating inside the glue barrel.

8. In case of air pressure or glue leakage of the hot melt adhesive coater, Hot melt adhesive coating machine never continue to use the hot melt adhesive coater. First stop the hot melt adhesive coater, cut off the power supply, and reduce the pressure of Cao to zero before maintenance.

9. Never maintain the hot melt adhesive coater in a flooded floor or non Chang humid environment.

10。 Dismantling and maintenance work, workers Zui do not have to wear earrings, watches, necklaces, bracelets and other conductive items, Hot melt adhesive coating machinewhich can prevent accidents.

When loosening or installing the pressure joint, Hot melt adhesive coating machine it must be determined that the pressure of the pressure air supply for the hot melt adhesive coater has been reduced to Zhi zero.
