FURTHER FEATURES

  • Progressive heating & melting: The glue’s heating component is positioned beneath it. Upon heating the melting tank, the bottom layer of the adhesive makes contact with the heat source, causing it to attain its melting point and transform into a liquid state. Simultaneously, no heat is applied to the upper portion of the adhesive container during this stage, which is necessary for production requirements. Consequently, determining an optimal quantity for melting becomes imperative in preventing long-term heat-induced aging and deterioration of the adhesive material.
  • The fluid can be isolated from the air when melting: The use conditions of PUR are guaranteed by a protective O-ring seal that separates the heating cylinder from the cylinder head, preventing any exposure of the melted liquid glue to air.
  • Teflon protective layer: The fluid tank is equipped with a Teflon coating on its outer surface, allowing for effortless removal of the adhesive. This not only prevents carbonization and ensures superior glue performance but also minimizes any potential clogs in the delivery system.
  • Adjustable fluid output: Accurate control of the glue volume output is achieved by utilizing a precision gear metering pump, implementing frequency conversion speed regulation, and ensuring stable motor operation.
  • Intelligent protection is adopted for motor operation: A forced fan is incorporated into the motor to facilitate heat dissipation. If the glue tank temperature doesn’t meet the set threshold, it prevents the motor from operating and ensures greater protection for its equipment.
  • Insufficient glue amount monitoring: The prevention of alarms triggered by insufficient or excessive amounts of glue is ensured by a lone electronic sensor that constantly monitors the quantity of glue present in the glue tank.
