People who use hot melt adhesive machines all know that after a long period of use, carbon deposits will inevitably form in the hot melt adhesive machines, and these carbon deposits will affect the application process. Therefore, hot melt adhesive machines need to be cleaned regularly. So, how should hot melt adhesive machines be cleaned?
Operation Steps:
1. Empty the residual glue in the glue tank of the hot melt adhesive machine
Set the temperature of the glue tank to 160 degrees Celsius, turn off the heating temperatures of the glue hoses and spray guns (set them to 0 degrees Celsius). When the hot melt adhesive in the glue tank is completely melted, open the glue drainage valve to empty the residual glue and take out the primary filter screen inside the glue tank, directly removing all the hot melt adhesive from the glue tank.
2. Soak and clean the glue tank of the hot melt adhesive machine with Banglin's special cleaning oil
Put in cleaning oil with a volume of about 80% of the capacity of the glue tank, set the temperature at around 120 degrees Celsius, soak for about one hour, and then drain the cleaning oil. If the hot melt adhesive in the glue tank is severely carbonized, you can wrap cotton cloth around a wooden stick to scrub the four walls and the bottom of the glue tank, and then drain the cleaning oil. Repeat the above process again with clean cleaning oil. (The oil drained for the second time can be reserved for the next cleaning to reduce waste.)
Precautions:
1. During the process of cleaning the hot melt adhesive machine, please wear protective glasses and heat-resistant gloves.
2. To ensure that the hot melt adhesive has been completely cleaned, multiple cleanings should be carried out to prevent residues from clogging the nozzles.
3. It is prohibited to mix different brands of hot melt adhesive.
4. Please close the lid of the glue tank during the production process to prevent debris or dust from falling in.
5. Generally, the filter screen is not cleaned but mainly replaced to ensure the stability and smoothness of the glue spraying system pressure.
